FrogHeart’s 2024 comes to an end as 2025 comes into view

Leave a reply

First, thank you to anyone who’s dropped by to read any of my posts. Second, I didn’t quite catch up on my backlog in what was then the new year (2024) despite my promises. (sigh) I will try to publish my drafts in a more timely fashion but I start this coming year as I did 2024 with a backlog of two to three months. This may be my new normal.

As for now, here’s an overview of FrogHeart’s 2024. The posts that follow are loosely organized under a heading but many of them could fit under other headings as well. After my informal review, there’s some material on foretelling the future as depicted in an exhibition, “Oracles, Omens and Answers,” at the Bodleian Libraries, University of Oxford.

Human enhancement: prosthetics, robotics, and more

Within a year or two of starting this blog I created a tag ‘machine/flesh’ to organize information about a number of converging technologies such as robotics, brain implants, and prosthetics that could alter our concepts of what it means to be human. The larger category of human enhancement functions in much the same way also allowing a greater range of topics to be covered.

Here are some of the 2024 human enhancement and/or machine/flesh stories on this blog,

Other species are also being rendered ‘machine/flesh’,

The year of the hydrogel?

It was the year of the hydrogel for me (btw, hydrogels are squishy materials; I have more of a description after this list),

As for anyone who’s curious about hydrogels, there’s this from an October 20, 2016 article by D.C.Demetre for ScienceBeta, Note: A link has been removed,

Hydrogels, materials that can absorb and retain large quantities of water, could revolutionise medicine. Our bodies contain up to 60% water, but hydrogels can hold up to 90%.

It is this similarity to human tissue that has led researchers to examine if these materials could be used to improve the treatment of a range of medical conditions including heart disease and cancer.

These days hydrogels can be found in many everyday products, from disposable nappies and soft contact lenses to plant-water crystals. But the history of hydrogels for medical applications started in the 1960s.

Scientists developed artificial materials with the ambitious goal of using them in permanent contact applications , ones that are implanted in the body permanently.

For anyone who wants a more technical explanation, there’s the Hydrogel entry on Wikipedia.

Science education and citizen science

Where science education is concerned I’m seeing some innovative approaches to teaching science, which can include citizen science. As for citizen science (also known as, participatory science) I’ve been noticing heightened interest at all age levels.

Artificial intelligence

It’s been another year where artificial intelligence (AI) has absorbed a lot of energy from nearly everyone. I’m highlighting the more unusual AI stories I’ve stumbled across,

As you can see, I’ve tucked in two tangentially related stories, one which references a neuromorphic computing story ((see my Neuromorphic engineering category or search for ‘memristors’ in the blog search engine for more on brain-like computing topics) and the other is intellectual property. There are many, many more stories on these topics

Art/science (or art/sci or sciart)

It’s a bit of a surprise to see how many art/sci stories were published here this year, although some might be better described as art/tech stories.

There may be more 2024 art/sci stories but the list was getting long. In addition to searching for art/sci on the blog search engine, you may want to try data sonification too.

Moving off planet to outer space

This is not a big interest of mine but there were a few stories,

A writer/blogger’s self-indulgences

Apparently books can be dangerous and not in a ‘ban [fill in the blank] from the library’ kind of way,

Then, there are these,

New uses for electricity,

Given the name for this blog, it has to be included,

  • Frog saunas published September 15, 2024, this includes what seems to be a mild scientific kerfuffle

I’ve been following Lomiko Metals (graphite mining) for a while,

Who would have guessed?

Another bacteria story,

New crimes,

Origins of life,

Dirt

While no one year features a large number of ‘dirt’ stories, it has been a recurring theme here throughout the years,

Regenerative medicine

In addition to or instead of using the ‘regenerative medicine’ tag, I might use ’tissue engineering’ or ’tissue scaffolding’,

To sum it up

It was an eclectic year.

Peering forward into 2025 and futurecasting

I expect to be delighted, horrified, thrilled, and left shaking my head by science stories in 2025. Year after year the world of science reveals a world of wonder.

More mundanely, I can state with some confidence that my commentary (mentioned in the future-oriented subsection of my 2023 review and 2024 look forward) on Quantum Potential, a 2023 report from the Council of Canadian Academies, will be published early in this new year as I’ve almost finished writing it.

As for more about the future, I’ve got this, from a December 3, 2024 essay (Five ways to predict the future from around the world – from spider divination to bibliomancy) about an exhibition by Michelle Aroney (Research Fellow in Early Modern History, University of Oxford) and David Zeitlyn (Professor of Social Anthropology, University of Oxford) in The Conversation (h/t December 3, 2024 news item on phys.org), Note: Links have been removed

Some questions are hard to answer and always have been. Does my beloved love me back? Should my country go to war? Who stole my goats?

Questions like these have been asked of diviners around the world throughout history – and still are today. From astrology and tarot to reading entrails, divination comes in a wide variety of forms.

Yet they all address the same human needs. They promise to tame uncertainty, help us make decisions or simply satisfy our desire to understand.

Anthropologists and historians like us study divination because it sheds light on the fears and anxieties of particular cultures, many of which are universal. Our new exhibition at Oxford’s Bodleian Library, Oracles, Omens & Answers, explores these issues by showcasing divination techniques from around the world.

…

1. Spider divination

In Cameroon, Mambila spider divination (ŋgam dù) addresses difficult questions to spiders or land crabs that live in holes in the ground.

Asking the spiders a question involves covering their hole with a broken pot and placing a stick, a stone and cards made from leaves around it. The diviner then asks a question in a yes or no format while tapping the enclosure to encourage the spider or crab to emerge. The stick and stone represent yes or no, while the leaf cards, which are specially incised with certain meanings, offer further clarification.

…

2. Palmistry

Reading people’s palms (palmistry) is well known as a fairground amusement, but serious forms of this divination technique exist in many cultures. The practice of reading the hands to gather insights into a person’s character and future was used in many ancient cultures across Asia and Europe.

In some traditions, the shape and depth of the lines on the palm are richest in meaning. In others, the size of the hands and fingers are also considered. In some Indian traditions, special marks and symbols appearing on the palm also provide insights.

Palmistry experienced a huge resurgence in 19th-century England and America, just as the science of fingerprints was being developed. If you could identify someone from their fingerprints, it seemed plausible to read their personality from their hands.

…

3. Bibliomancy

If you want a quick answer to a difficult question, you could try bibliomancy. Historically, this DIY [do-it-yourself] divining technique was performed with whatever important books were on hand.

Throughout Europe, the works of Homer or Virgil were used. In Iran, it was often the Divan of Hafiz, a collection of Persian poetry. In Christian, Muslim and Jewish traditions, holy texts have often been used, though not without controversy.

…

4. Astrology

Astrology exists in almost every culture around the world. As far back as ancient Babylon, astrologers have interpreted the heavens to discover hidden truths and predict the future.

…

5. Calendrical divination

Calendars have long been used to divine the future and establish the best times to perform certain activities. In many countries, almanacs still advise auspicious and inauspicious days for tasks ranging from getting a haircut to starting a new business deal.

In Indonesia, Hindu almanacs called pawukon [calendar] explain how different weeks are ruled by different local deities. The characteristics of the deities mean that some weeks are better than others for activities like marriage ceremonies.

Oracles, Omens and Answers

6 December 2024 – 27 April 2025
ST Lee Gallery, Weston Library

The Bodleian Libraries’ new exhibition, Oracles, Omens and Answers, will explore the many ways in which people have sought answers in the face of the unknown across time and cultures. From astrology and palm reading to weather and public health forecasting, the exhibition demonstrates the ubiquity of divination practices, and humanity’s universal desire to tame uncertainty, diagnose present problems, and predict future outcomes.

Through plagues, wars and political turmoil, divination, or the practice of seeking knowledge of the future or the unknown, has remained an integral part of society. Historically, royals and politicians would consult with diviners to guide decision-making and incite action. People have continued to seek comfort and guidance through divination in uncertain times — the COVID-19 pandemic saw a rise in apps enabling users to generate astrological charts or read the Yijing [I Ching], alongside a growth in horoscope and tarot communities on social media such as ‘WitchTok’. Many aspects of our lives are now dictated by algorithmic predictions, from e-health platforms to digital advertising. Scientific forecasters as well as doctors, detectives, and therapists have taken over many of the societal roles once held by diviners. Yet the predictions of today’s experts are not immune to criticism, nor can they answer all our questions.

Curated by Dr Michelle Aroney, whose research focuses on early modern science and religion, and Professor David Zeitlyn, an expert in the anthropology of divination, the exhibition will take a historical-anthropological approach to methods of prophecy, prediction and forecasting, covering a broad range of divination methods, including astrology, tarot, necromancy, and spider divination.

Dating back as far as ancient Mesopotamia, the exhibition will show us that the same kinds of questions have been asked of specialist practitioners from around the world throughout history. What is the best treatment for this illness? Does my loved one love me back? When will this pandemic end? Through materials from the archives of the Bodleian Libraries alongside other collections in Oxford, the exhibition demonstrates just how universally human it is to seek answers to difficult questions.

Highlights of the exhibition include: oracle bones from Shang Dynasty China (ca. 1250-1050 BCE); an Egyptian celestial globe dating to around 1318; a 16th-century armillary sphere from Flanders, once used by astrologers to place the planets in the sky in relation to the Zodiac; a nineteenth-century illuminated Javanese almanac; and the autobiography of astrologer Joan Quigley, who worked with Nancy and Ronald Reagan in the White House for seven years. The casebooks of astrologer-physicians in 16th- and 17th-century England also offer rare insights into the questions asked by clients across the social spectrum, about their health, personal lives, and business ventures, and in some cases the actions taken by them in response.

The exhibition also explores divination which involves the interpretation of patterns or clues in natural things, with the idea that natural bodies contain hidden clues that can be decrypted. Some diviners inspect the entrails of sacrificed animals (known as ‘extispicy’), as evidenced by an ancient Mesopotamian cuneiform tablet describing the observation of patterns in the guts of birds. Others use human bodies, with palm readers interpreting characters and fortunes etched in their clients’ hands. A sketch of Oscar Wilde’s palms – which his palm reader believed indicated “a great love of detail…extraordinary brain power and profound scholarship” – shows the revival of palmistry’s popularity in 19th century Britain.

The exhibition will also feature a case study of spider divination practised by the Mambila people of Cameroon and Nigeria, which is the research specialism of curator Professor David Zeitlyn, himself a Ŋgam dù diviner. This process uses burrowing spiders or land crabs to arrange marked leaf cards into a pattern, which is read by the diviner. The display will demonstrate the methods involved in this process and the way in which its results are interpreted by the card readers. African basket divination has also been observed through anthropological research, where diviners receive answers to their questions in the form of the configurations of thirty plus items after they have been tossed in the basket.

Dr Michelle Aroney and Professor David Zeitlyn, co-curators of the exhibition, say:

Every day we confront the limits of our own knowledge when it comes to the enigmas of the past and present and the uncertainties of the future. Across history and around the world, humans have used various techniques that promise to unveil the concealed, disclosing insights that offer answers to private or shared dilemmas and help to make decisions. Whether a diviner uses spiders or tarot cards, what matters is whether the answers they offer are meaningful and helpful to their clients. What is fun or entertainment for one person is deadly serious for another.

Richard Ovenden, Bodley’s [a nickname? Bodleian Libraries were founded by Sir Thomas Bodley] Librarian, said:

People have tried to find ways of predicting the future for as long as we have had recorded history. This exhibition examines and illustrates how across time and culture, people manage the uncertainty of everyday life in their own way. We hope that through the extraordinary exhibits, and the scholarship that brings them together, visitors to the show will appreciate the long history of people seeking answers to life’s biggest questions, and how people have approached it in their own unique way.

The exhibition will be accompanied by the book Divinations, Oracles & Omens, edited by Michelle Aroney and David Zeitlyn, which will be published by Bodleian Library Publishing on 5 December 2024.

From AI to Ancient Greece; the 2024-25 theatre season at Concordia University (Montréal, Québec)

Leave a reply

An October 30, 2024 Concordia University news release by Vanessa Hauguel announces the upcoming theatre season, which features a focus on how current technology and historical narratives intersect, Note: Links have been removed,

The Concordia Department of Theatre recently announced its 2024-25 season, featuring a diverse lineup of scripted and devised works. The program delves into themes relevant to today’s world, from artificial intelligence (AI) and deepfakes to the timeless human experiences and societal change.

Two upcoming productions highlight the department’s wide range of creative approaches. The first is Concord Floral by Jordan Tannahill, directed by Emma Tibaldo. The second is a devised adaptation of La vida es sueño (Life is a Dream), based on Pedro Calderón de la Barca’s classic play, directed by Peter Farbridge.

While these two productions kick off the season, additional performances are planned throughout the year until April 2025, continuing the department’s exploration of contemporary and classic themes. Directors Farbridge and Tibaldo, as well as this season’s artistic producer, Noah Drew, share the creative vision behind the shows and the thematic connections between them.

Modern ghost story

Concord Floral, by Canadian playwright Tannahill, is a modern ghost story set in an abandoned greenhouse where a group of teenagers face a buried secret. Directed by Tibaldo, a Concordia theatre graduate, 99, and artist-in-residence, it incorporates cutting-edge technology to navigate themes of guilt, adolescence and the weight of collective silence.

“Concord Floral is a play that sticks with you,” Tibaldo explains. “It speaks to growing up, discovering yourself and grappling with your accountability to others. The haunting or ‘plague’ in the play is represented through movement, lighting and sound, creating a visceral embodiment of guilt and regret.”

The play draws on The Decameron as a point of reference, adding a sense of timelessness to the teenage experience. “During our teen years, we often react or make impulsive decisions, as we’re discovering or aiming to break boundaries, and sometimes they come with lasting consequences,” Tibaldo says. “This play will resonate strongly with many, as it captures that intense, confusing period of early adulthood.”

La vida es sueño: mixing AI, deepfakes & philosophy

Meanwhile, La vida es sueño offers a reimagining of Calderón de la Barca’s work, making allusions to contemporary issues like AI deepfakes. Farbridge, MA 22, explores the philosophical themes of illusion and reality in this adaptation, examining how modern technology manipulates perception.

“At the heart of the play is the idea that our lives are shaped by false narratives, a timeless concept that feels increasingly relevant in today’s world,” Farbridge says.

“Our adaptation looks at how political systems manipulate truth on a massive scale. And the deeper question we’re asking is, if belief in what we see and hear in online media collapses, where will we land?”

Farbridge’s production will use a combination of video screens, shadow-play and physical performance to explore these themes. “We’re experimenting with form and trying to find new ways of engaging with the audience. It’s an exciting process, and unnerving too, as we won’t know the full impact of it until the public is in the theatre with us..”

A season of learning and innovating

As this season’s artistic producer, Drew sees the productions as essential learning experiences for students. “A big part of students’ education has to come from ‘stage time’ — those moments when a live audience is experiencing their work,” the associate professor says.

“These two productions offer a chance to engage with classic stories radically reinvented —Concord Floral reinterprets The Decameron, while La vida es sueño rethinks a Spanish Golden Age play. I hope it gives students the opportunity to see how historical narratives can connect with today’s issues, and grasp a deeper, more personal understanding of how history loops and cycles.”

Drew also points out the importance of technology in both productions.

“Lighting, sound and video are used all the time in many forms of art and entertainment media. What’s special about their use in theatre is that audiences get to see them in a real three-dimensional space interacting with our species’ original ‘technology’ — the human body. This liveness and immediacy can create almost-hallucinatory images that make audiences rub their eyes and wonder if the haunting moments in Concord Floral or the manipulations of truth in La vida es sueño are illusions or are really happening.”

Reflecting on the broader significance of theatre, Drew believes that storytelling plays a vital role in addressing the challenges of today’s rapidly changing world.

“We live in a time of war, climate crises, political polarization, flawed AI, and many forms of injustice,” he says. “Theatre can help us step outside of our routines, wake up, and yearn for more. It’s a way to make sense of a complicated world and spark inspiration.”

La vida es sueño (Life is a Dream) runs from November 14 to 16 [2024] in room 240 of the Molson (MB) Building, 1450 Guy Street.

Concord Floral runs November 27 to 30 [2024] at the Concordia Theatre in the Henry F. Hall (H) Building, 1455 Boulevard De Maisonneuve West.

Happy Canada Day! Breakdancing at the 2024 Paris Summer Olympics: physics in action + heat, mosquitoes, and sports

Leave a reply

Happy July 1, 2024, also known as, Canada Day!

Onto breakdancing (or breaking), which for the first time will be an official event at the 2024 Paris Summer Olympics. Amy Pope, principal lecturer, physics and astronomy, Clemson University (South Carolina, US), has written a June 12, 2024 essay for The Conversation that describes breakdancing as physics in action, (h/t June 13, 2024 news item in phys.org), Note: Links have been removed,

Two athletes square off for an intense dance battle. The DJ starts spinning tunes, and the athletes begin twisting, spinning and seemingly defying gravity, respectfully watching each other and taking turns showing off their skill.

The athletes converse through their movements, speaking through a dance that celebrates both athleticism and creativity. While the athletes probably aren’t consciously thinking about the physics behind their movements, these complex and mesmerizing dances demonstrate a variety of different scientific principles.

Breaking, also known as breakdancing, originated in the late 1970s in the New York City borough of the Bronx. Debuting as an Olympic sport in the 2024 Summer Olympics, breaking will showcase its dynamic moves on a global stage. This urban dance style combines hip-hop culture, acrobatic moves and expressive footwork.

Since its inception, breaking has evolved into a competitive art form. An MC narrates the movements, while a DJ mixes songs to create a dynamic atmosphere. The Olympics will feature two events: one for men, called B-boys, and one for women, called B-girls. In these events, athletes will face off in dance battles.

… Success in this sport requires combining dance moves from three basic categories: top rock, down rock and freeze.

…

And now for the physics of it all, from Pope’s June 12, 2024 essay, Note: Links have been removed,

…

Top rock moves [emphasis mine] are performed while standing up, focusing on fancy footwork and hand movements. These movements are reminiscent of hip-hop dancing.

Top rock moves rely on having lots of friction between an athlete’s shoes and the floor. Friction is the force [emphasis miine] that resists when you slide something across a surface.

This friction allows the athlete to take very quick steps and to stop abruptly. The dancers must intuitively understand inertia, or the fact that their bodies will continue in the direction they’re moving unless they are acted upon by an external force. To stop abruptly, athletes need to engage their muscles, getting their shoes to grip the ground to stop themselves from continuing forward.

…

Down rock moves [emphasis mine] are performed while on the floor. Athletes may spin in circles with their head, back, elbows or shoulders touching the ground and their feet in the air. B-boys and B-girls rely heavily on an internal knowledge of physics to complete these moves.

Consider the physics of a backspin. A backspin occurs when the athlete is on their back with their feet lifted in the air, rotating around a specific area of their back.

Sitting on the floor, the athlete’s left foot stays in contact with the floor while they spread their right leg wide, gathering linear momentum [emphasis mine] as they sweep their right leg toward their left foot in a wide arc. Then, they release their left leg from contact with the ground and roll onto their back.

Now that only their back is in contact with the ground, the linear momentum from their leg turns into angular momentum [emphasis mine], which rotates the athlete around an axis that extends upward from their back’s contact point with the ground. This move turns magical when they bring their legs and arms inward, toward the axis of rotation. This principal is called conservation of angular momentum.

When an athlete brings their mass in more closely to the axis of rotation, the athlete’s rotations speed up. Extending their legs and arms once again and moving their mass away from the axis of rotation will cause the competitor to slow their rotation speed down. Once they slow down, they can transition to another move.

…

Freeze [emphasis mine] occurs when athletes come to a stop in a funky pose, often occurring in time to the music and in an upside-down position. To freeze effectively, the athlete must have full control over their center of mass, placing it right above the point of their body that is in contact with the floor. The center of mass is the average position of all the parts of an athlete, weighted according to their masses. The “balance point” where the entire mass of the athlete seems to be concentrated is the center of mass.

Athletes are most stable when their center of mass is as close to the ground as possible. You will see many competitors freeze with arms bent in an effort to lower their center of mass. This lowered center of mass reduces their distance from the floor and minimizes the tendency of their body to rock to one side or the other due to torque.

Torque is a twisting force [emphasis mine], like the force used to turn a wrench. The torque depends on two things: the amount of force you apply, and how far from the pivot point you apply the force. With an athlete’s center of mass closer to the ground, the athlete decreases the distance between the pivot point – the ground – and where the force of gravity is applied – the athlete’s center of mass.

Athletes need great strength to halt their motion mid-movement because they have to apply a force to resist the change in inertia.

…

It’s not just about the moves, clothing is a factor, Pope’s June 12, 2024 essay,

Many sports require a specific uniform. Breaking doesn’t – an athlete can wear whatever they want – but the right outfit will maximize their chance of success.

The athlete wants a shirt that minimizes the friction between their body and the ground during a spin. Lettering or images on the back of the shirt will add friction, which hinders an athlete’s ability to perform some down rock moves. An athlete may choose to wear long sleeves if they plan to slide on their elbows, as bare skin in contact with the floor provides more friction.

Athletes also have to think about the headgear they wear. …

There’s a bit more information about the breakdancing competition on the 2024 Olympics website.I cannot find a full list of athletes for the August 9, 2024 (B-Girls) and August 10, 2024 (B-Boys) competitions. There is this June 2, 2024 article (from the Associated Press) on the CBC (Canadian Broadcasting Corporation) online news website,

…

Victor Montalvo (B-boy Victor), United States: A breaker who describes himself as a student of old school b-boys from the founding era of hip-hop, the 30-year-old Montalvo, who is from Kissimmee, Florida, qualified for Paris by besting all other b-boys at the 2023 WDSF World Breaking Championship in Belgium.

Sunny Choi (B-girl Sunny), United States: The 35-year-old Choi, a cheerful Queens, New York-bred breaker, has long been an ambassador for b-girls globally. She qualified for the Paris Games with her win at the 2023 Pan American Games in Chile.

Philip Kim (B-boy Phil Wizard), Vancouver, Canada: Consistently ranked in the top three b-boys in the international breaking competitive community, Kim secured a spot for Paris when he came out on top at last year’s Pan American Games.

Dominika Banevič (B-girl Nicka), Lithuania: Banevič was the youngest in her category at last year’s WDSF World Breaking Championship, when she punched her ticket to Paris. Banevič turns 17 this month.

…

I thought the competition would be dominated by Americans and certainly wasn’t expecting to see a Lithuanian (Dominika Banevič or ‘Nicka’) listed as a competitor to watch. The Canadian (Philip Kim or ‘Phil Wizard’) is also a surprise. Who knew Vancouver was home to a leading B-boy?

Two comments: heat and mosquitoes (dengue and other fevers)

The organizers of the Paris 2024 Summer Olympics are to be complimented for their work towards making the games ‘green’ but that is a complex process.

Heat

For example, the Canadian Broadcasting Corporation (CBC) ran a news item on The National news telecast on June 17, 2024 (see telecast for embedded video clip) regarding concerns about and preparations for heat,

Preparing for extreme heat at the Paris Olympics

Paris Olympic organizers plan to make this summer’s games the greenest ever, but that includes offering less air conditioning to cut down on energy use. [emphases mine] As temperatures rise globally, some suggest the organizers should take extreme heat into account when awarding cities with the next big Olympic games.

Some of the reporting in the CBC news item is based on information from a June 18, 2024 University of Portsmouth (UK) press release, Note: Links have been removed,

Leading athletes are warning that intense heat at the Paris Olympics in July-August 2024 could lead to competitors collapsing and in worst case scenarios dying during the Games. [emphasis mine]

Eleven Olympians, including winners of five World Championships and six Olympic medals, have come together with climate scientists and leading heat physiologists Professor Mike Tipton and Dr Jo Corbett from the University of Portsmouth to unpack the serious threat extreme heat poses for athletes in a new Rings of Fire report.

Dr Corbett, Associate Professor of Environmental Physiology in the School of Sport, Health and Exercise Science at the University of Portsmouth, said: “A warming planet will present an additional challenge to athletes, which can adversely impact on their performance and diminish the sporting spectacle of the Olympic Games,. Hotter conditions also increase the potential for heat illness amongst all individuals exposed to high thermal stress, including officials and spectators, as well as athletes.”

“For athletes, from smaller performance-impacting issues like sleep disruption and last-minute changes to event timings, to exacerbated health impacts and heat related stress and injury, the consequences can be varied and wide-ranging. With global temperatures continuing to rise, climate change should increasingly be viewed as an existential threat to sport,” said Lord Sebastian Coe, President of World Athletics and four-time Olympic medallist.

The Tokyo Games became known as the “hottest in history,” with temperatures exceeding 34°C and humidity reaching nearly 70 per cent, leading to severe health risks for competitors. The Paris Games have the potential to surpass that, with climate change driven by the burning of fossil fuels contributing to record heat streaks during the past months.

2023 was the hottest year on record according to the EU’s [European Union] Copernicus Climate Change Service and 2024 has continued this streak. April 2024 was warmer globally than any previous April in the record books, said experts at Copernicus.

The Rings of Fire report discusses the deadly heatwave in France in 2003 – which killed over 14,000 people – and subsequent years of record-breaking temperatures, exceeding 42°C. It underscores the heightened risk of extreme heat during the Paris Olympics, especially considering the significant rise in the region’s temperatures since the city last hosted the Games a century ago.

Mosquitoes and dengue and other fevers

Obviously, the world is changing as you can see in this June 18, 2024 Institut Pasteur press release (also on EurekAlert),

Olympics: how many days does it take for mosquitoes in Greater Paris to transmit arboviruses, and what preventive measures are needed?

The number of imported cases of dengue in the Greater Paris region increased significantly in the first few months of 2024. In the run-up to the Olympic Games, with huge numbers of international visitors set to come to Paris – especially from endemic dengue countries –, we need to be vigilant. Scientists from the Institut Pasteur, in collaboration with the Regional Mosquito Control Agency (ARD) and the National Reference Center for Arboviruses (Inserm-Irba), have demonstrated that the tiger mosquito, now present in Greater Paris, is capable of transmitting five viruses (West Nile, chikungunya, Usutu, Zika and dengue) within different time frames ranging from 3 to 21 days, at an external temperature of 28°C. These results highlight the importance of stepping up surveillance of imported cases of arboviruses this summer. The study was published on May 16 [2024] in Eurosurveillance.

Between January 1 and April 19, 2024, 1,679 imported dengue cases were reported in mainland France, 13 times more than the number reported over the same period the previous year (source SPF). It is likely that this number will increase during the Olympic Games, as more people come to Paris from countries that are endemic regions for other arboviruses. The vector for dengue transmission is Aedes albopictus, more commonly known as the tiger mosquito. Arboviruses are transmitted when a female mosquito bites a virus carrier and ingests viral particles. One particular feature of arboviruses is that they can replicate in mosquitoes (unlike other viruses such as influenza, which are destroyed when ingested by mosquitoes). The viral particles multiply and spread within the mosquito, reaching the salivary glands in a few days. When the female mosquito bites another human, she injects the virus while taking her blood meal.

The tiger mosquito is now present in 78 départements in mainland France, and this together with other climate change-related factors is facilitating vector-borne transmission. Scientists from the Institut Pasteur’s Arboviruses and Insect Vectors Unit, in collaboration with the Regional Vector Control Agency (ARD) and the National Reference Center for Arboviruses (Inserm-Irba), therefore decided to analyze the ability of Aedes albopictus in Greater Paris to transmit five arboviruses at a temperature of 28°C, which is likely in the region at this time of year, and counted the number of days between initial infection and the possibility of the virus being transmitted through a further mosquito bite. As well as the dengue, chikungunya and Zika viruses, which we already know can be transmitted by the tiger mosquito, the scientists studied the Usutu and West Nile viruses, which are naturally transmitted by another mosquito species, Culex pipiens (known as the “common mosquito”). Culex pipiens mosquitoes transmit viruses to humans after feeding on birds, which act as viral reservoirs.

Tiger mosquito susceptible to five arboviruses

Working in a BSL3 laboratory, the scientists studied the ability of tiger mosquitoes to transmit these five viruses and determined the extrinsic incubation period required for the virus to reach the mosquito’s salivary glands in sufficient quantities to infect a human. At 28°C, West Nile virus needs three days before it can be transmitted to humans by mosquitoes. The incubation period is 3 to 7 days for chikungunya and Usutu, and 14 to 21 days for dengue and Zika.(1) 

This information is crucial to gage the additional risk represented by the upcoming Olympic Games in Paris, which will see significant intermingling of populations combined with the return of travelers from endemic regions and a season conducive to mosquito proliferation. The findings can also be used to develop suitable control strategies.

“If a case of dengue is detected in the Greater Paris region, we now know that disinsection is required within 21 days. We can use these results to adjust our time frame for action and optimize our approach,” explains Anna-Bella Failloux, Head of the Institut Pasteur’s Arboviruses and Insect Vectors Unit, who led the study. “Depending on the temperatures we experience in and around Paris this summer, our findings will be essential for adjusting control measures as needed.”

What precautions should be taken in the run-up to the Olympics?

Health care professionals are trained to detect the symptoms of arboviruses if people indicate that they have recently been to an endemic country. The difficulty of surveillance is that many cases are asymptomatic: although dengue is a notifiable disease, up to 80% of cases lead to few or no symptoms. If a diagnosis of one of these diseases is confirmed, an inquiry is carried out by France’s Regional Health Agencies to determine where the individuals live or spent time in the days before the diagnosis, so that they can identify the areas where disinsection is needed. Anyone coming back from a foreign trip who experiences fever or aches is advised to see their family physician immediately and indicate the region they recently returned from.

“The alert system in France is effective. The applicable procedure and measures are already well established because France’s overseas territories in endemic regions have provided us with expertise in these diseases and know-how on epidemiological monitoring. My team is affiliated with the Arbo-France network, and we are contacted as soon as an arbovirus is detected,” continues Anna-Bella Failloux.

Since 2006, vector control measures in France have led to increased surveillance of tiger mosquitoes between May 1 and November 30 each year. This involves monitoring mosquito populations in areas where they are likely to be present; disease surveillance coordinated by Santé publique France based on reporting of viruses such as dengue, chikungunya and Zika by health care professionals; and raising awareness among people living in areas where mosquitoes have been reported. France’s Regional Health Agencies (ARS) and their operators are responsible for managing reporting, monitoring the presence of mosquitoes and taking rapid action in response to human cases of infection (vector control).

This research, which focused on mosquitoes in the Greater Paris region for this first study, will soon be extended to the rest of mainland France. Extrinsic incubation periods vary from one tiger mosquito population to the next because of differences in their genetic makeup and in local temperatures.

I covered the movement of dengue fever and malaria into the Northern Hemisphere in an August 10, 2023 posting,

…

The World Health Organization (WHO) notes that dengue fever cases have increased exponentially since 2000 (from the March 17, 2023 version of the WHO’s “Dengue and severe dengue” fact sheet),

Global burden

The incidence of dengue has grown dramatically around the world in recent decades, with cases reported to WHO increased from 505 430 cases in 2000 to 5.2 million in 2019. A vast majority of cases are asymptomatic or mild and self-managed, and hence the actual numbers of dengue cases are under-reported. Many cases are also misdiagnosed as other febrile illnesses (1).

One modelling estimate indicates 390 million dengue virus infections per year of which 96 million manifest clinically (2). Another study on the prevalence of dengue estimates that 3.9 billion people are at risk of infection with dengue viruses.

The disease is now endemic in more than 100 countries in the WHO Regions of Africa, the Americas, the Eastern Mediterranean, South-East Asia and the Western Pacific. The Americas, South-East Asia and Western Pacific regions are the most seriously affected, with Asia representing around 70% of the global disease burden.

Dengue is spreading to new areas including Europe, [emphasis mine] and explosive outbreaks are occurring. Local transmission was reported for the first time in France and Croatia in 2010 [emphasis mine] and imported cases were detected in 3 other European countries.

…

The researchers from the University of Central Florida (UCF) couldn’t have known when they began their project to study mosquito bites and disease that Florida would register its first malaria cases in 20 years this summer, …

It seems pretty clear that there’s increasing concern about mosquito-borne diseases no matter where you live.

It looks like mega-sports events attract more visitors than you might expect.

Climate measurements as music

Leave a reply

Given that it was Earth Day yesterday (April 22, 2024), this seems like a good second act. From an April 18, 2024 news item on phys.org,

A geo-environmental scientist from Japan has composed a string quartet using sonified climate data. The 6-minute-long composition—titled “String Quartet No. 1 “Polar Energy Budget”—is based on over 30 years of satellite-collected climate data from the Arctic and Antarctic and aims to garner attention on how climate is driven by the input and output of energy at the poles.

…

This is a little longer video than I usually like to embed here at 6 mins. 29 secs. and it is one of the more aesthetically pleasing I’ve heard,

An April 18, 2024 Cell Press press release, which originated the news item, describes the data sonification work and its application to art/science projects, Note: A link has been removed,

“I strongly hope that this manuscript marks a significant turning point, transitioning from an era where only scientists handle data to one where artists can freely leverage data to craft their works,” writes author and composer Hiroto Nagai, a geo-environmental scientist at Rissho University.

Scientist-composer Hiroto Nagai asserts that music, as opposed to sound, evokes an emotional response and posits that “musification” (as opposed to sonification) of data requires some intervention by the composer to build tension and add dynamics. For this reason, Nagai was more liberal in adding a “human touch” compared to previous data-based musical compositions, aiming to meld sonification with traditional music composition.

“As a fundamental principle in music composition, it is necessary to combine temporal sequences from tension-building to resolution in various scales, from harmonic progressions to entire movements,” Nagai writes. “So far, there haven’t been published attempts and open discussion on sonification-based music composition, nor attempts to demonstrate the methodology required to intentionally affect the audience’s emotions with an artistic piece.”

To do this, he first used a program to sonify environmental data by assigning sounds to different data values. The publicly available data was collected from four polar locations between 1982 and 2022: an ice-core drilling site in the Greenland ice sheet, a satellite station in Norway’s Svalbard archipelago, and two Japanese-owned research stations in the Antarctic (Showa Station and Dome Fuji Station). For each of the sites, Nagai used data on monthly measurements of short- and longwave radiation, precipitation, surface temperature, and cloud thickness.

In the next step, he transformed this collection of sounds into a musical composition to be played by two violins, a viola, and a cello. This process involved many steps, including manipulating the pitch of different datapoints and assigning sections of data to the different instruments, overlaying passages created from different data, and introducing musical playing techniques such as pizzicato and staccato. Nagai also intervened in more artistic ways by introducing rhythm, deliberately removing certain sounds, and introducing handwritten (non-data derived) parts into the composition.

The quartet’s premiere live performance was shared at Waseda University in Tokyo in March 2023 followed by a panel discussion. A filmed performance of the piece by PRT Quartet, a Japanese professional string quartet, was also released on YouTube in March 2023.

“Upon listening, my initial reaction was like, ‘What is this?’ It felt like a typical contemporary piece,” said Haruka Sakuma, the professional violinist who performed 2nd violin. “The flow of the music was a bit hard to memorize quickly, and it was quite challenging at first.”

Nagai says that, in contrast to graphical representations of data, music elicits emotion before intellectual curiosity and suggests that using graphical and music representations of data in conjunction might be even more powerful.

“It grabs the audiences’ attention forcefully, while graphical representations require active and conscious recognition instead,” Nagai writes. “This reveals the potential for outreach in the Earth sciences through music.”

How can ballet performances become more accessible? Put a sensor suit on the dancers*

Leave a reply

Take a look,

While this December 20, 2023 news item on phys.org is oriented to Christmas, it applies to much more,

Throughout the festive season, countless individuals delight in the enchantment of ballet spectacles such as “The Nutcracker.” Though the stories of timeless performances are widely known, general audiences often miss the subtle narratives and emotions dancers seek to convey through body movements—and they miss even more when the narratives are not based on well-known stories.

This prompts the question: how can dance performances become more accessible for people who are not specialists? [emphasis mine]

Researchers think they have the answer, which involves putting dancers in sensor suits.

…

Putting dancers into sensor suits would not have been my first answer to that question.

A December 20, 2023 Loughborough University (UK) press release, which originated the news item, describes the international research project, the Kinesemiotic Body, and its sensor suits Note: A link has been removed,

Loughborough University academics are working with the English National Ballet and the University of Bremen [Germany] to develop software that will allow people to understand the deeper meanings of performances by watching annotated CGI [computer-generated imagery] videos of different dances.

Leading this endeavour is former professional ballerina Dr Arianna Maiorani, an expert in ‘Kinesemiotics – the study of meaning conveyed through movement – and the creator of the ‘Functional Grammar of Dance’ (FGD), a model that deciphers meaning from dance movements.

Dr Maiorani believes the FGD – which is informed by linguistics and semiotics (the study of sign-based communication) theories – can help create visualisations of ‘projections’ happening during dance performances to help people understand what the dance means.

“Projections are like speech bubbles made by movement”, explains Dr Maiorani, “They are used by dancers to convey messages and involve extending body parts towards significant areas within the performance space.

“For example, a dancer is moving towards a lake, painted on the backdrop of a stage. They extend an arm forward towards the lake and a leg backwards towards a stage prop representing a shed. The extended arm means they are going to lake, while the leg means they are coming from shed.

“Using the Functional Grammar of Dance, we can annotate dances –filling the projection speech bubbles with meaning that people can understand without having background knowledge of dance.”

Dr Maiorani and a team of computer science and technology experts – including Loughborough’s Professor Massimiliano Zecca, Dr Russell Lock, and Dr Chun Liu – have been creating CGI videos of English National Ballet dancers to use with the FGD.

This involved getting dancers – including First Soloist Junor Souza and First Artist Rebecca Blenkinsop – to perform individual movements and phrases while wearing sensors on their head, torso, and limbs.

Using the FGD, they decoded the conveyed meanings behind different movements and annotated the CGI videos accordingly.

The researchers are now investigating how these videos can facilitate engagement for audiences with varying levels of dance familiarity, aiming to eventually transform this research into software for the general public.

Of the ultimate goal for the research, Dr Maiorani said: “We hope that our work will improve our understanding of how we all communicate with our body movement, and that this will bring more people closer to the art of ballet.”

The Loughborough team worked with experts from the University of Bremen including Professor John Bateman and Ms Dayana Markhabayeva, and experts from English National Ballet. The research was funded by the AHRC-DFG and supported by the LU Institute of Advanced Studies.

They are also looking at how the FDG can be used in performance and circus studies, as well as analysing character movements within video games to determine any gender biases.

You can find the Kinesemiotic Body here, where you’ll find this academic project description, Note: Links have been removed,

The Kinesemiotic Body is a joint research project funded by Deutsche Forschungsgemeinschaft (DFG) and  Arts & Humanities Research Council  (AHRC) in cooperation with the English National Ballet (ENB). The project brings together an interdisciplinary group of researchers with the aim of evaluating whether a description of dance discourse informed by multimodal discourse analysis and visualised through enriched videos can capture the way dance communicates through a flow of choreographed sequences in space, and whether this description can support the interpretative process of nonexpert audiences. The theoretical framework of the research project is based on an extended dynamic theory called segmented discourse representation theory (SDRT) and on the Functional Grammar of Dance Movement created by Project Investigator Maiorani. Project’s long-term goal is to develop an interdisciplinary area of research focusing on movement-based communication that can extend beyond the study of dance to other movement-based forms of communication and performance and foster the creation of partnerships between the academia and the institutions that host and promote such disciplines.

It’s been a while since I’ve had a piece that touches on multimodal discourse.

Overall winner of the 2024 global Dance Your PhD: Kangaroo Time (Club Edit)

Leave a reply

I can’t resist the dance. First, the submission for the American Association for the Advancement of Science (AAAS) Dance Your Ph.D. competition on Youtube and then, the video,

Science and Artistic Rationale:

In our 2024 AAAS [American Association for the Advancement of Science]/Science Magazine Dance Your Ph.D. Contest submission, we explore kangaroo behavior through dance and promote diversity. The performance, titled “Kangaroo Time”, is based on my [Weliton Menário Costa] Ph.D. field research at Wilsons Promontory National Park, Australia, conducted at the Australian National University in collaboration with the University of Sherbrooke, Canada. My thesis, “Personality, Social Environment, and Maternal-Level Effects: Insights from a Wild Kangaroo Population”, is accessible here: https://openresearch-repository.anu.e…. I am honored to have worked under the expert supervision of Prof Loeske Kruuk and Prof Marco Festa-Bianchet. We delve into animal personality, defined as consistent behavior that distinguishes individuals, and social plasticity, the extent to which behavior changes in response to the social environment. We explain how both personality traits and social environment influence kangaroo behavior, including responses to stimuli like a remote-controlled car, and we demonstrate the role of personality on social dynamics. The diversity of the dancers, ranging from classical to urban styles, reflects the variations in kangaroo personality, e.g. bolder to shier. These dancers, unchoreographed, improvise their movements, responding to cues and interacting with each other. The dance thus serves as a visual narrative, capturing how kangaroos react based not only on their instincts but also on their social context. This approach demonstrates that kangaroo decisions are a complex interplay of intrinsic tendencies (personality) and social awareness leading to adjustment (plasticity). I hope this performance makes the scientific concepts both accessible and engaging for the audience. I completed my Ph.D. at the Australian National University, Canberra, in 2021, and worked as a Research Officer. Now, I’m pursuing music, having released my debut EP “Yours Academically, Dr. WELI” and the single “Kangaroo Time (Club Edit),” featured in the video. This project represents a fusion of my scientific work and my foray into performance and creative arts, combining animal behavior with artistic expression.

A February 26, 2024 Australian National University (ANU) press release on EurekAlert provides more detail about the researcher and about his work with kangaroos, Note: Links have been removed,

Dr Weliton Menário Costa, a PhD graduate from The Australian National University (ANU), has been announced the overall winner of the 2024 global Dance Your PhD contest after wowing judges with his wickedly creative and quirky dance submission, ‘Kangaroo Time (Club Edit)’.

One of the world’s leading researchers in kangaroo behaviour, he is the first person from ANU to win the Dance Your PhD competition, and just the fourth person from an Australian institution to do so since its inception in 2008. Better known as ‘WELI’, the singer-songwriter, creator and biologist weaves together a funky beat, original songwriting, drag queens and Brazilian funk dancers to create something that’s both entertaining and educational; the final product is something that looks like it’s been plucked straight out of The Adventures of Priscilla, Queen of the Desert.

WELI stars in and directs the music video, which draws on his Brazilian roots to illustrate the distinct and varying personality traits of kangaroos using the powerful mediums of song and dance. The original and club mixes have been played more than 7,000 times on Spotify, and the song has already featured in clubs, festivals, dance classes and radio stations.

“Winning this contest is the equivalent of winning Eurovision for me. I think it not only shows the incredible might of the research conducted here in Australia, but also how creative we are as a nation. Even us scientists!” he said.

Reflecting on the success of ‘Kangaroo Time’ and the global mark it’s made on the scientific community and further afield, WELI notes that at the core of his video is a message of inclusivity and diversity – something he hopes will be one of the main takeaways that viewers hold onto.

“As a queer immigrant from a linguistically diverse developing country, I understand the challenges of feeling disconnected in certain environments,” he said.

“One of the main messages I wanted to convey through this piece of work is that differences lead to diversity, and this is evident throughout the entire video. It’s evident with the different dancers that herald from various cultures and backgrounds.

“I think it’s extremely important that we celebrate diversity and creating a video explaining kangaroo personality was an excellent medium for me to do this.”

In 2017, WELI relocated from his home country of Brazil to Canberra to undertake a PhD in animal behaviour at the ANU Research School of Biology, which he finished in 2021.

Armed with a remote-controlled car, the ANU graduate spent more than three years studying the spectrum of behavioural differences of a group of more than 300 wild eastern grey kangaroos in Victoria.

“We found that kangaroos like to socialise in groups but prefer smaller social circles. Like humans, kangaroo personalities manifest early in life. Mothers and their offspring have similar personalities, and so do siblings,” he said.

“Kangaroos are very socially aware and will adjust their behaviour based off cues from other roos.

“The diversity of the dancers, from classical ballet to twerking, and the urban street dancers to the Brazilian dancing styles, reflect the variations in kangaroo personality across the full spectrum, from bolder types to shier roos.”

On the surface, ‘Kangaroo Time’ is an effective display of science communication that expertly utilises the creative arts medium. It’s engaging, quirky and niche. But WELI admits the decision to incorporate the words kangaroo time into the video’s title acts as a double entendre of sorts.

“The use of kangaroo time is not just to explain my research studying kangaroo personality – it’s also about my time living and studying in Australia as a whole,” he said.

“It’s been a time of exploration for me, a time where I’ve been able to reconnect with and grow my passion for music, dance and the creative arts.

“Working on this project was the spark I needed to encourage me to take that next step with my music. It’s made me realise I want to focus on my music for the next little while and put my scientific career on the backburner.

“Speaking of which, I’m about to release a new EP called ‘Yours Academically, Dr WELI’!”

WELI will continue working at ANU as a Visiting Fellow until early 2025.

The Dance Your PhD contest challenges researchers from across the globe to explain their PhD in a simple, effective and engaging way – bridging the gap between the scientific community and the general public.

There’s more about WELI in George Booth’s February 27, 2024 article (‘It’s like winning Eurovision’: an ANU graduate’s journey from kangaroo whisperer to global dance sensation) for ANU Reporter.

It was nice to stumble across a ‘Dance your PhD contest’ story. Unfortunately, that doesn’t happen often. I have two previous postings (from 2011and 2018) about the contest. Strangely, both are Canadian-centric,

Enjoy!

Poinsettia frogs and a Merry 2023 Christmas

A new (!) fanged frog in Indonesia

This is not the tiny Indonesian fanged frog but it does show you what a fanged frog looks like, from the December 21, 2023 “What Are Fanged Frogs?” posting on the Vajiram and Ravi IAS Study Center website,

Not an Indonesian fanged frog. h/t Vajiram and Ravi IAS Study Center [downloaded from https://vajiramias.com/current-affairs/what-are-fanged-frogs/658416a9f0e178517404afda/]

If you don’t have much time and are interested in the latest fanged frog, check out the December 21, 2023 “What Are Fanged Frogs?” posting as they have relevant information in bullet point form.

On to the specifics about the ‘new’ fanged frog from a December 21, 2023 news item on ScienceDaily,

In general, frogs’ teeth aren’t anything to write home about — they look like pointy little pinpricks lining the upper jaw. But one group of stream-dwelling frogs in Southeast Asia has a strange adaptation: two bony “fangs” jutting out of their lower jawbone. They use these fangs to battle with each other over territory and mates, and sometimes even to hunt tough-shelled prey like giant centipedes and crabs. In a new study, published in the journal PLOS [Public Library of Science] ONE, researchers have described a new species of fanged frog: the smallest one ever discovered.

“This new species is tiny compared to other fanged frogs on the island where it was found, about the size of a quarter,” says Jeff Frederick, a postdoctoral researcher at the Field Museum in Chicago and the study’s lead author, who conducted the research as a doctoral candidate at the University of California, Berkeley.

…

A December 20, 2023 Field Museum news release (also on EurrekAlert), which originated the news item, adds more detail,

“Many frogs in this genus are giant, weighing up to two pounds. At the large end, this new species weighs about the same as a dime.”

In collaboration with the Bogor Zoology Museum, a team from the McGuire Lab at Berkeley   found the frogs on Sulawesi, a rugged, mountainous island that makes up part of Indonesia. “It’s a giant island with a vast network of mountains, volcanoes, lowland rainforest, and cloud forests up in the mountains. The presence of all these different habitats mean that the magnitude of biodiversity across many plants and animals we find there is unreal – rivaling places like the Amazon,” says Frederick.

While trekking through the jungle, members of the joint US-Indonesia amphibian and reptile research team noticed something unexpected on the leaves of tree saplings and moss-covered boulders: nests of frog eggs.

Frogs are amphibians, and they lay eggs that are encapsulated by jelly, rather than a hard, protective shell. To keep their eggs from drying out, most amphibians lay their eggs in water. To the research team’s surprise, they kept spotting the terrestrial egg masses on leaves and mossy boulders several feet above the ground. Shortly after, they began to see the small, brown frogs themselves.

“Normally when we’re looking for frogs, we’re scanning the margins of stream banks or wading through streams to spot them directly in the water,” Frederick says. “After repeatedly monitoring the nests though, the team started to find attending frogs sitting on leaves hugging their little nests.” This close contact with their eggs allows the frog parents to coat the eggs with compounds that keep them moist and free from bacterial and fungal contamination.

Closer examination of the amphibian parents revealed not only that they were tiny members of the fanged frog family, complete with barely-visible fangs, but that the frogs caring for the clutches of eggs were all male. “Male egg guarding behavior isn’t totally unknown across all frogs, but it’s rather uncommon,” says Frederick.

Frederick and his colleagues hypothesize that the frogs’ unusual reproductive behaviors might also relate to their smaller-than-usual fangs. Some of the frogs’ relatives have bigger fangs, which help them ward off competition for spots along the river to lay their eggs in the water. Since these frogs evolved a way to lay their eggs away from the water, they may have lost the need for such big imposing fangs. (The scientific name for the new species is Limnonectes phyllofolia; phyllofolia means “leaf-nester.”)

“It’s fascinating that on every subsequent expedition to Sulawesi, we’re still discovering new and diverse reproductive modes,” says Frederick. “Our findings also underscore the importance of conserving these very special tropical habitats. Most of the animals that live in places like Sulawesi are quite unique, and habitat destruction is an ever-looming conservation issue for preserving the hyper-diversity of species we find there. Learning about animals like these frogs that are found nowhere else on Earth helps make the case for protecting these valuable ecosystems.”

Fatal attraction to … frog noses?

Bob Yirka in a November 28, 2023 article published on phys.org describes research into some unusual mosquito behaviour, Note: Links have been removed,

A pair of environmental and life scientists, one with the University of Newcastle, in Australia, the other the German Center for Integrative Biodiversity Research, has found that one species of mosquito native to Australia targets only the noses of frogs for feeding. In their paper published in the journal Ethology, John Gould and Jose Valdez describe their three-year study of frogs and Mimomyia elegans, a species of mosquito native to Australia

As part of their study of frogs living in a pond on Kooragang Island, the pair took a lot of photographs of the amphibians in their native environment. It was upon returning to their lab and laying out the photographs that they noticed something unique—any mosquito feeding on a frog’s blood was always atop its nose. This spot, they noted, seemed precarious, as mosquitos are part of the frog diet.

Sheena Goodyear posted a December 13, 2023 article containing an embedded Canadian Broadcasting Corporation (CBC) As It Happens radio programme audio file of an interview with researcher John Gould, Note: A link has been removed,

…

So why risk landing on the nose of something that wants to eat you, when there are so many other targets walking around full of delicious blood?

“In all of the occasions that we observed, it seems as if the frog didn’t realize that it had a mosquito on top of it…. They were actually quite happy, just sitting idly, while these mosquitoes were feeding on them,” Gould said.

“So it might be that the area between the eyes is a bit of a blind spot for the frogs.”

It’s also something of a sneak attack by the mosquitoes.

“Some of the mosquitoes first initially landed on the backs of the frogs,” Gould said. “They might avoid being eaten by the frogs by landing away from the head and then walking up to the nostrils to feed.

It’s a plausible theory, says amphibian expert Lea Randall, a Calgary Zoo and Wilder Institute ecologist who wasn’t involved in the research. 

“Frogs have amazing vision, and any mosquito that approached from the front would likely end up as a tasty snack for a frog,” she said.

“Landing on the back and making your way undetected to the nostrils is a good strategy.”

And the reward may just be worth the risk. 

“I could also see the nostrils as being a good place to feed as the skin is very thin and highly vascularized, and thus provides a ready source of blood for a hungry mosquito,” Randall said.

…

Gould admits his friends and loved ones have likely grown weary of hearing him “talking about frogs and nostrils.” But for him, it’s more than a highly specific scientific obsession; it’s about protecting frogs.

His earlier research has suggested that mosquitoes may be a vector for transmitting amphibian chytrid fungus, which is responsible for declines in frog populations worldwide. 

That’s why he had been amassing photos of frogs and mosquitoes in the first place.

“Now that we know where the mosquito is more likely to land, it might give us a better impression about how the infection spreads along the skin of the frog,” he said.

…

But more work needs to be done. His frog nostril research, while it encompasses three years’ of fieldwork, is a natural history observation, not a laboratory study with controlled variables.

“It would be quite interesting to know whether this particular type of mosquito is transferring the chytrid fungus, and also how the fungus spreads once the mosquito has landed,” Gould said.

…

A December 14, 2023 news item on phys.org describes some intriguing research from Hungary,

All dog owners think that their pups are special. Science now has documented that some rare dogs are even more special. They have a talent for learning hundreds of names of dog toys. Due to the extreme rarity of this phenomenon, until recently, very little was known about these dogs, as most of the studies that documented this ability included only a small sample of one or two dogs.

A December 18,2023 Eötvös Loránd University (ELTE) press release (also on EurekAlert but published December 14, 2023), which originated the news item, delves further into the research,

In a previous study, the scientists found that only very few dogs could learn the names of object, mostly dog toys. The researchers wanted to understand this phenomenon better and, so they needed to find more dogs with this ability. But finding dogs with this rare talent was a challenge! For five years, the researchers tirelessly searched across the world for these unique Gifted Word Learner (GWL) dogs. As part of this search, in 2020, they launched a social media campaign and broadcasted their experiments with GWL dogs, in the hope of finding more GWL dogs.

“This was a citizen science project” explains Dr. Claudia Fugazza, team leader. “When a dog owner told us they thought their dog knew toy names, we gave them instructions on how to self-test their dog and asked them to send us the video of the test”. The researchers then held an online meeting with the owners to test the dog’s vocabulary under controlled conditions and, if the dog showed he knew the names of his toys, the researchers asked the owners to fill out a questionnaire. “In the questionnaire, we asked the owners about their dog’s life experience, their own experience in raising and training dogs, and about the process by which the dog came to learn the names of his/her toys” explains Dr. Andrea Sommese, co-author.

VIDEO ABSTRACT ABOUT THE RESEARCH

The researchers found 41 dogs from 9 different countries: the US, the UK, Brazil, Canada, Norway, Netherlands, Spain, Portugal and Hungary. Most of the previous studies on this topic included Border collies. So, while object label learning is very rare even in Border collies, it was not surprising that many of the dogs participating in the current study (56%) belonged to this breed. However, the study documented the ability to learn toy names in a few dogs from non-working breeds, such as two Pomeranians, one Pekingese, one Shih Tzu, a Corgi, a Poodle, and a few mixed breeds.

“Surprisingly, most owners reported that they did not intentionally teach their dogs toy names, but rather that the dogs just seemed to spontaneously pick up the toy names during unstructured play sessions,” says Shany Dror, lead researcher. In addition, the vast majority of owners participating in the study had no professional background in dog training and the researchers found no correlations between the owners’ level of experience in handling and training dogs, and the dogs’ ability to select the correct toys when hearing its names.

“In our previous studies we have shown that GWL dogs learn new object names very fast” explains Dror. “So, it is not surprising that when we conducted the test with the dogs, the average number of toys known by the dogs was 29, but when we published the results, more than 50% of the owners reported that their dogs had already acquired a vocabulary of over 100 toy names”.

“Because GWL dogs are so rare, until now there were only anecdotes about their background” explains Prof. Adam Miklósi, Head of the Ethology Department at ELTE and co-author. “The rare ability to learn object names is the first documented case of talent in a non-human species. The relatively large sample of dogs documented in this study, helps us to identify the common characteristics that are shared among these dogs, and brings us one step closer in the quest of understanding their unique ability”.

This research is part of the Genius Dog Challenge research project which aims to understand the unique talent that Gifted Word Learner dogs have. The researchers encourage dog owners who believe their dogs know multiple toy names, to contact them via the Genius Dog Challenge website.

The End with an origin story NORAD’s Santa Tracker and some tap dancing

At the height of Cold War tensions between the US and Russia, the red phone (to be used only by the US president or a four star genera) rang at the North American Aerospace Defense Command (NORAD). Before the conversation ended, the colonel in charge had driven a child to tears and put in motion the start of a beloved Christmas tradition.

There’s a short version and a long version and if you want all the details read both,

As for the tap dancing, I have three links:

  1. “Irish Dancers Face Off Against American Tap Dancers To Deliver EPIC Performance!” is an embedded 8 mins. dance off video (scroll down past a few paragraphs) in Erin Perri’s September 1, 2017 posting for themix.net. And, if you scroll further down to the bottom of Perri’s post, you’ll see an embedded video of Sammy Davis Jr.

…

In the video …, along with his dad and uncle, Sammy performs at an unbelievable pace. In the last 30 seconds of this routine, Sammy demonstrates more talent than other dancers are able to cram into a lifelong career! You can see these three were breakdancing long before it became a thing in the 1980s and they did it wearing tap shoes!

..

2. “Legendary Nicholas Brothers Dance Routine Was Unrehearsed and Filmed in One Take” embedded at the end of Emma Taggart’s October 4, 2019 posting on mymodernmet.com

3. Finally, there’s “Jill Biden releases extravagant dance video to celebrate Christmas at the White House” with a video file embedded (wait for it to finish loading and scroll down a few paragraphs) in Kate Fowler’s December 15, (?) 2023 article for MSN. It’s a little jazz, a little tap, and a little Christmas joy.

Joyeux Noël!

The World Cultural Council is soliciting nominations for two awards, one for science and one for the arts. Before giving a few details about the call for awards nominations, here’s a few about the organization, from the World Cultural Council’s About Us webpage,

The World Cultural Council is a non-profit international organization, founded in Mexico, whose objectives are to promote culture, values and goodwill throughout the world. One of the means by which it strives to do so is by granting the Albert Einstein World Award of Science, the José Vasconcelos World Award of Education and the Leonardo da Vinci World Award of Arts to outstanding personalities whose work has had a significantly positive impact on the cultural legacy of mankind. The members of the Council include several Nobel laureates.

It was in 1982, on the inspiration of 124 distinguished scholars, university presidents and organization executives from the world over, that the WCC was founded and, in 1984, the first Award Ceremony took place.

The World Cultural Council is composed of a directing body headed by an Honorary President, Vice-president, Executive Director, Secretary General and an Interdisciplinary Committee made up of outstanding scientific, artistic and educational personalities.

The Interdisciplinary Committee evaluates annually the candidates nominated to participate in the “Albert Einstein“, the “José Vasconcelos” and the “Leonardo da Vinci” Awards
