News about an entire brain-machine interface (BMI) on a chip comes from an August 26, 2024 École Polytechnique Fédérale de Lausanne (EPFL) press release (also on EurekAlert), Note: Links have been removed,

Brain-machine interfaces (BMIs) have emerged as a promising solution for restoring communication and control to individuals with severe motor impairments. Traditionally, these systems have been bulky, power-intensive, and limited in their practical applications. Researchers at EPFL have developed the first high-performance, Miniaturized Brain-Machine Interface (MiBMI), offering an extremely small, low-power, highly accurate, and versatile solution. Published in the latest issue of the IEEE Journal of Solid-State Circuits and presented at the International Solid-State Circuits Conference, the MiBMI not only enhances the efficiency and scalability of brain-machine interfaces but also paves the way for practical, fully implantable devices. This technology holds the potential to significantly improve the quality of life for patients with conditions such as amyotrophic lateral sclerosis (ALS) and spinal cord injuries.

The MiBMI’s small size and low power are key features, making the system suitable for implantable applications. Its minimal invasiveness ensures safety and practicality for use in clinical and real-life settings. It is also a fully integrated system, meaning that the recording and processing are done on two extremely small chips with a total area of 8mm2. Thisis the latest in a new class of low-power BMI devices developed at Mahsa Shoaran’s Integrated Neurotechnologies Laboratory (INL) at EPFL’s IEM and Neuro X institutes. 

“MiBMI allows us to convert intricate neural activity into readable text with high accuracy and low power consumption.This advancement brings us closer to practical, implantable solutions that can significantly enhance communication abilities for individuals with severe motor impairments,” says Shoaran.  

Brain-to-text conversion involves decoding neural signals generated when a person imagines writing letters or words. In this process, electrodes implanted in the brain record neural activity associated with the motor actions of handwriting. The MiBMI chipset then processes these signals in real-time, translating the brain’s intended hand movements into corresponding digital text. This technology allows individuals, especially those with locked-in syndrome and other severe motor impairments, to communicate by simply thinking about writing, with the interface converting their thoughts into readable text on a screen.

“While the chip has not yet been integrated into a working BMI, it has processed data from previous live recordings, such as those from the Shenoy lab at Stanford [Stanford University in California, US}, converting handwriting activity into text with an impressive 91% accuracy,” says lead author Mohammed Ali Shaeri. The chip can currently decode up to 31 different characters, an achievement unmatched by any other integrated systems. “We are confident that we can decode up to 100 characters, but a handwriting dataset with more characters is not yet available,” adds Shaeri. 

Current BMIs record the data from electrodes implanted in the brain and then send these signals to a separate computer to do the decoding. The MiBMI chips records the data but also processes the information in real time—integrating a 192-channel neural recording system with a 512-channel neural decoder. This neurotechnological breakthrough is a feat of extreme miniaturization that combines expertise in integrated circuits, neural engineering, and artificial intelligence. This innovation is particularly exciting in the emerging era of neurotech startups in the BMI domain, where integration and miniaturization are key focuses. EPFL’s MiBMI offers promising insights and potential for the future of the field.

To be able to process the massive amount of information picked up by the electrodes on the miniaturized BMI, the researchers had to take a completely different approach to data analysis. They discovered that the brain activity for each letter, when the patient imagines writing it by hand, contains very specific markers, which the researchers have named distinctive neural codes (DNCs). Instead of processing thousands of bytes of data for each letter, the microchip only needs to process the DNCs, which are around a hundred bytes. This makes the system fast, accurate, and with low-power consumption.  This breakthrough also allows for faster training times, making learning how to use the BMI easier and more accessible. 

Collaborations with other teams at EPFL’s Neuro-X and IEM Institutes, such as with the laboratories of Grégoire Courtine, Silvestro Micera, Stéphanie Lacour, and David Atienza promise to create the next generation of integrated BMI systems. Shoaran, Shaeri and their team are exploring various applications for the MiBMI system beyond handwriting recognition. “We are collaborating with other research groups to test the system in different contexts, such as speech decoding and movement control. Our goal is to develop a versatile BMI that can be tailored to various neurological disorders, providing a broader range of solutions for patients,” says Shoaran.

Sprayable gels could protect buildings during wildfires

This seems like a good idea especially for those of us who live in areas where wildfires have become commonplace, from an August 22, 2024 news item on ScienceDaily,

As climate change creates hotter, drier conditions, we are seeing longer fire seasons with larger, more frequent wildfires. In recent years, catastrophic wildfires have destroyed homes and infrastructure, caused devastating losses in lives and livelihoods of people living in affected areas, and damaged wildland resources and the economy. We need new solutions to fight wildfires and protect areas from damage.

Researchers at Stanford have developed a water-enhancing gel that could be sprayed on homes and critical infrastructure to help keep them from burning during wildfires [emphasis mine]. The research, published Aug. 21 [2024] in Advanced Materials, shows that the new gels last longer and are significantly more effective [emphasis mine] than existing commercial gels.

An August 21, 2024 Stanford University news release (also on EurekAlert but published August 22, 2024), which originated the news item, delves further into the research, Note: Links have been removed,

“Under typical wildfire conditions, current water-enhancing gels dry out in 45 minutes,” said Eric Appel, associate professor of materials science and engineering in the School of Engineering, who is senior author of the paper. “We’ve developed a gel that would have a broader application window – you can spray it further in advance of the fire and still get the benefit of the protection – and it will work better when the fire comes.

Long-lasting protection

Water-enhancing gels are made of super-absorbent polymers – similar to the absorbent powder found in disposable diapers. Mixed with water and sprayed on a building, they swell into a gelatinous substance that clings to the outside of the structure, creating a thick, wet shield. But the conditions in the vicinity of a wildfire are extremely dry – temperatures can be near 100 degrees, with high winds and zero percent humidity – and even water locked in a gel evaporates fairly quickly.

In the gel designed by Appel and his colleagues, the water is just the first layer of protection. In addition to a cellulose-based polymer, the gel contains silica particles, which get left behind when the gels are subjected to heat. “We have discovered a unique phenomenon where a soft, squishy hydrogel seamlessly transitions into a robust aerogel shield under heat, offering enhanced and long-lasting wildfire protection. This environmentally conscious breakthrough surpasses current commercial solutions, offering a superior and scalable defense against wildfires,” said the lead author of the study, Changxin “Lyla” Dong.

“When the water boils off and all of the cellulose burns off, we’re left with the silica particles assembled into a foam,” Appel said. “That foam is highly insulative and ends up scattering all of the heat, completely protecting the substrate underneath it.”

The silica forms an aerogel – a solid, porous structure that is a particularly good insulator. Similar silica aerogels are used in space applications because they are extremely lightweight and can prevent most methods of heat transfer.

The researchers tested several formulations of their new gel by applying them to pieces of plywood and exposing them to direct flame from a gas hand-torch, which burns at a considerably higher temperature than a wildfire. Their most effective formulation lasted for more than 7 minutes before the board began to char. When they tested a commercially available water-enhancing gel in the same way, it protected the plywood for less than 90 seconds.

“Traditional gels don’t work once they dry out,” Appel said. “Our materials form this silica aerogel when exposed to fire that continues to protect the treated substrates after all the water has evaporated. These materials can be easily washed away once the fire is gone.”

A serendipitous discovery

The new gels build off of Appel’s previous wildfire prevention work. In 2019, Appel and his colleagues used these same gels as a vehicle to hold wildland fire retardants on vegetation for months at a time. The formulation was intended to help prevent ignition in wildfire-prone areas.

“We’ve been working with this platform for years now,” Appel said. “This new development was somewhat serendipitous – we were wondering how these gels would behave on their own, so we just smushed some on a piece of wood and exposed it to flames from a torch we had laying around the lab. What we observed was this super cool outcome where the gels puffed up into an aerogel foam.”

After that initial success, it took several years of additional engineering to optimize the formulation. It is now stable in storage, easily sprayable with standard equipment, and adheres well to all kinds of surfaces. The gels are made of nontoxic components that have already been approved for use by the U.S. Forest Service, and the researchers conducted studies to show that they are easily broken down by soil microbes.

“They’re safe for both people and the environment,” Appel said. “There may need to be additional optimization, but my hope is that we can do pilot-scale application and evaluation of these gels so we can use them to help protect critical infrastructure when a fire comes through.”

Back to school: Stanford University (California) brings nanoscience to teachers and Ingenium brings STEAM to school

I have two stories that fit into the ‘back to school’ theme, one from Stanford University and one from Ingenium (Canada’s Museums of Science and Innovation).

Stanford, nanoscience, and middle school teachers

h/t to Google Alert of August 27, 2024 (received via email) for information about a Stanford University programme for middle school teachers. From an August 27, 2024 article in the Stanford Report, Note: Links have been removed,

Crafting holographic chocolate, printing with the power of the sun, and seeing behind the scenes of cutting-edge research at the scale of one-billionth of a meter, educators participating in the Nanoscience Summer Institute for Middle School Teachers (NanoSIMST) got to play the role of students, for a change.

Teachers hailed from the Bay Area and Southern California – one had even come all the way from Arkansas – for the professional development program. NanoSIMST, run by nano@stanford, is designed to connect middle school teachers with activities, skills, and knowledge about science at the scale of molecules and atoms so they can incorporate it into their curriculum. NanoSIMST also prioritizes teachers from Title I schools, which are low-income schools with low-income student populations that receive federal funding to improve academic achievement.

Debbie Senesky, the site investigator and principal researcher on the nano@stanford project, highlighted the importance of nanoscience at the university. “It’s not just about focusing on research – we also have bigger impacts on entrepreneurs, start-ups, community colleges, and other educators who can use these facilities,” said Senesky, who is also an associate professor of aeronautics and astronautics and of electrical engineering. “We’re helping to train the next generation of people who can be a workforce in the nanotechnology and semiconductor industry.”

The program also supports education and outreach, including through NanoSIMST, which uniquely reaches out to middle school teachers due to the STEM education outcomes that occur at that age. According to a 2009 report by the Lemelson-MIT InvenTeam Initiative, even among teens who were interested in and felt academically prepared in their STEM studies, “nearly two-thirds of teens indicated that they may be discouraged from pursuing a career in science, technology, engineering or mathematics because they do not know anyone who works in these fields (31%) or understand what people in these fields do (28%).”

A teacher from the Oakland Unified School District, Thuon Chen, connected several other teachers from OUSD to attend NanoSIMST as a first-time group. He emphasized that young kids, especially in middle school, have a unique way of approaching new technologies. “Kids have this sense where they’re always pushing things and coming up with completely new uses, so introducing them to a new technology can give them a lot to work with.”

Over the course of four days in the summer, NanoSIMST provides teachers with an understanding of extremely small science and technology: they go through tours of the nano facilities, speak with scientists, perform experiments that can be conducted in the classroom, and learn about careers in nanotechnology and the semiconductor industry.

Tara Hodge, the teacher who flew all the way from Arkansas, was thrilled about bringing what she learned back with her. “I’m not a good virtual learner, honestly. That’s why I came here. And I’m really excited to learn about different hands-on activities. Anything I can get excited about, I know I can get my students excited about.”

They have provided a video,

One comment regarding the host, Daniella Duran, the director of education and outreach for nano@stanford, she comments about nano being everywhere and, then, says “… everything has a microchip in it.” I wish she’d been a little more careful with the wording. Granted those microchips likely have nanoscale structures.

For more details about the sisters and the performance, Marilyn R. Wilson has written up a February 21, 2024 interview with both sisters for her Olio blog,

Can you share a little bit about your background, the life, work, experiences that led you to who you are today?
Kayla: I’m a visual artist with a focus on fashion design, and textile development. I like to explore ways to create wearable art with minimal waste produced in the process. I studied painting at Azadehgan School of Art in Iran and fashion design & technology at Wilson School of Design in Vancouver. My interest in fashion is rooted in creating functional art. I enjoy the business aspect of fashion however, I want to push boundaries of how fashion can be seen as art rather than solely as production.

Kimia: I’m a composer of acoustic and electronic music, I perform and build instruments, and a lot of times I combine these components together. Working with various disciplines is also an important part of my practice. I studied piano performance at Tehran Music School before moving to Vancouver to study composition at Simon Fraser University. I am currently a doctorate candidate in music composition at Stanford University. I love electronic music, food, and sports! My family, partner, and friends are a huge part of my life!

You have your premier event called “Interweave” coming up on March 21st at The Kent Gallery in Vancouver. What can guests attending expect this evening?

Kayla & Kimia: Interweave is a multidisciplinary performance that bridges fashion, music, technology, and dance. Our dancers will be performing in garments designed by Kayla, that are embedded with microcontrollers and sensors developed by Kimia. The dancers control various musical parameters through their movements and their interaction with the sensors that are incorporated within the garments. Along with works for movement and dance, there will be a live electronic music performance made for costume-made instruments. So far we have received an amazing amount of support and RSVP’s from the art industry in Vancouver and look forward to welcoming many local creative individuals.

We’d love to know about the team of professionals who are working hard to create this unique experience. 

Kayla & Kimia: We are working with the amazing choreographers/dancers Anya Saugstad and Daria Mikhailiuk. We are thankful for Laleh Zandi’s help for creating a sculpture for one of our instruments which will be performed by Kimia. Celeste Betancur and Richard Lee have been our amazing audio tech assistants. We are very appreciative of everyone involved in FXE’s premiere and can’t wait to showcase our hard work.

I have a bit more about Kimia Koochakzadeh-Yazdi and her work in music from a February 27, 2024 profile on the SFU School for the Contemporary Arts website, Note: Links have been removed,

Please introduce yourself.

I’m a composer of acoustic and electronic music, I perform and build instruments, and a lot of times, I combine these components together. Working with various disciplines is also an important part of my practice. I studied piano performance at Tehran Music School before moving to Vancouver to study composition at Simon Fraser University, graduating from the SCA in 2020. I am currently a doctoral student in music composition at Stanford University, where I spend most of my time.

Tell us about your current studies.

I’m in the third year of the DMA (Doctor of Musical Arts) program at Stanford University. I do the majority of my work at the Center for Computer Research in Music and Acoustics (CCRMA). I’m currently trying to learn and to experiment as much as possible! The amount of resources and ideas that I have been exposed to during the last couple of years has been quite significant and wonderful. I have been taking courses in subjects that I never thought I would study, from classes in the computer science and the mechanical engineering departments, to ones in education and theatre. I’m grateful to have been given a supportive platform to truly experiment and to learn.

As for my compositions, they are more melodic than before, and that currently makes me happy. I have started to perform more again (piano and electronics), and it makes me question: why did I ever stop…?

Koochakzadeh-Yazdi’s mention of building instruments reminded me of Icelandic musician, Bjork and Biophilia, which was an album, various art projects, and a film (Biophilia Live), which featured a number of musical instruments she created.

Getting back to Interweave, it’ s on March 21, 2024 at The Kent, specifically the gallery, which has,

… 14 foot ceilings boasts 50 track lights with the ability to transform the vacuous hall from candlelight to daylight. The lights are fully dimmable in an array of playful hues, according to your whim.   A full array of DMX Lighting and control systems live alongside the track light system and our recently installed (Vancouvers only) immersive projection system [emphasis mine] is ready for your vision.  This is your show.

I wonder if ‘multi-sensory’ includes an immersive experience.

Don’t forget, you have to RSVP for Interweave, which is free.

Using measurements to generate quantum entanglement and teleportation

interesting approach to illustrating a complex scientific concept! This October 18, 2023 news item on phys.org describes the measurement problem,

Quantum mechanics is full of weird phenomena, but perhaps none as weird as the role measurement plays in the theory. Since a measurement tends to destroy the “quantumness” of a system, it seems to be the mysterious link between the quantum and classical world. And in a large system of quantum bits of information, known as “qubits,” the effect of measurements can induce dramatically new behavior, even driving the emergence of entirely new phases of quantum information.

This happens when two competing effects come to a head: interactions and measurement. In a quantum system, when the qubits interact with one another, their information becomes shared nonlocally in an “entangled state.” But if you measure the system, the entanglement is destroyed. The battle between measurement and interactions leads to two distinct phases: one where interactions dominate and entanglement is widespread, and one where measurements dominate, and entanglement is suppressed.

An October 18, 2023 Google Quantum AI news release, which originated the news item, on EurekAlert provides more information about a research collaboration between Google and Stanford University,

As reported today [October 18, 2023] in the journal Nature, researchers at Google Quantum AI and Stanford University have observed the crossover between these two regimes — known as a “measurement-induced phase transition” — in a system of up to 70 qubits. This is by far the largest system in which measurement-induced effects have been explored. The researchers also saw signatures of a novel form of “quantum teleportation” — in which an unknown quantum state is transferred from one set of qubits to another — that emerges as a result of these measurements. These studies could help inspire new techniques useful for quantum computing.

One can visualize the entanglement in a system of qubits as an intricate web of connections. When we measure an entangled system, the impact it has on the web depends on the strength of the measurement. It could destroy the web completely, or it could snip and prune selected strands of the web, but leave others intact. 

To actually see this web of entanglement in an experiment is notoriously challenging. The web itself is invisible, so researchers can only infer its existence by seeing statistical correlations between the measurement outcomes of qubits. Many, many runs of the same experiment are needed to infer the pattern of the web. This and other challenges have plagued past experiments and limited the study of measurement-induced phase transitions to very small system sizes. 

To address these challenges, the researchers used a few experimental sleights of hand. First, they rearranged the order of operations so that all the measurements could be made at the end of the experiment, rather than interleaved throughout, thus reducing the complexity of the experiment. Second, they developed a new way to measure certain features of the web with a single “probe” qubit. In this way, they could learn more about the entanglement web from fewer runs of the experiment than had been previously required. Finally, the probe, like all qubits, was susceptible to unwanted noise in the environment. This is normally seen as a bad thing, as noise can disrupt quantum calculations, but the researchers turned this bug into a feature by noting that the probe’s sensitivity to noise depended on the nature of the entanglement web around it. They could therefore use the probe’s noise sensitivity to infer the entanglement of the whole system.

The team first looked at this difference in sensitivity to noise in the two entanglement regimes and found distinctly different behaviors. When measurements dominated over interactions (the “disentangling phase”), the strands of the web remained relatively short. The probe qubit was only sensitive to the noise of its nearest qubits. In contrast, when the measurements were weaker and entanglement was more widespread (the “entangling phase”) the probe was sensitive to noise throughout the entire system. The crossover between these two sharply contrasting behaviors is a signature of the sought-after measurement-induced phase transition.

The team also demonstrated a novel form of quantum teleportation that emerged naturally from the measurements: by measuring all but two distant qubits in a weakly entangled state, stronger entanglement was generated between those two distant qubits. The ability to generate measurement-induced entanglement across long distances enables the teleportation observed in the experiment.

The stability of entanglement against measurements in the entangling phase could inspire new schemes to make quantum computing more robust to noise. The role that measurements play in driving new phases and physical phenomena is also of fundamental interest to physicists. Stanford professor and co-author of the study, Vedika Khemani, says, “Incorporating measurements into dynamics introduces a whole new playground for many-body physics where many fascinating and new types of non-equilibrium phases could be found. We explore a few of these striking and counter-intuitive measurement induced phenomena in this work, but there is much more richness to be discovered in the future.” 

Before getting to the citation for and link to the paper, I have an interview with some of the researchers that was written up by Holly Alyssa MacCormick (Associate Director of Public Relations. Science writer and news editor for Stanford School of Humanities and Sciences) in an October 18, 2023 article for Stanford University, Note 1: Some of this will be redundant; Note 2: Links have been removed,

Harnessing the “weirdness” of quantum mechanics to solve practical problems is the long-standing promise of quantum computing. But much like the state of the cat in Erwin Schrödinger’s famous thought experiment, quantum mechanics is still a box of unknowns. Similar to the solid, liquid, and gas phases of matter, the organization of quantum information, too, can assume different phases. Yet unlike the phases of matter we are familiar with in everyday life, the phases of quantum information are much harder to formulate and observe and as a result have been only a theoretical dream until recently.

Measurements are arguably the weirdest facet of quantum mechanics. Intuition tells us that a state has some definite property and measurement reveals that property. However, measurements in quantum mechanics produce intrinsically random results, and the act of measurement irreversibly changes the state itself. Unlike laptops, smartphones, and other classical computers that rely on binary “bits” to code in the state of 0 (off) or 1 (on), quantum computers use “qubits” of information that can be in the state of 0, 1, or 0 and 1 at the same time, a concept known as superposition. The act of measurement doesn’t just extract information, but also changes the state, randomly “collapsing” a superposition into a specific value (0 or 1).

Moreover, this collapse affects not just the qubit that was measured, but also potentially the entire system—an effect described by Einstein as “spooky action at a distance.” This is due to “entanglement,” a quantum property that allows multiple particles in different places to jointly be in superposition, which is a key ingredient for quantum computing. The collapse of an entangled state can also enable spooky phenomena such as “teleportation,” thereby irretrievably altering the “arrow of time” (the concept that time moves in one forward direction) that governs our everyday experience.

In other words, measurements can be used to fundamentally reorganize the structure of quantum information in space and time.

Now, a new collaboration between Stanford and Google Quantum AI investigates the effect of measurements on quantum systems of many particles on Google’s quantum computer and has obtained the largest experimental demonstration of novel measurement-induced phases of quantum information to date. The study was co-led by Jesse Hoke, a physics graduate student and fellow at Stanford’s Quantum Science and Engineering initiative (Q-FARM), Matteo Ippoliti, a former postdoctoral scholar in the Department of Physics, and senior author Vedika Khemani, associate professor of physics at the Stanford School of Humanities and Sciences and Q-FARM. Their results were published Oct. 18 in the journal Nature.

Here, Hoke, Ippoliti, and Khemani discuss how they observed measurement-induced phases of quantum information—a feat once thought to be beyond the realm of what could be achieved in an experiment—and how their new insights could help pave the way for advancements in quantum science and engineering.

Question: What distinguishes the phases investigated in this study from one another, and what is teleportation?

Ippoliti: In the simplest case, there are two phases. In one phase, the structure of quantum information in the system forms a strongly connected web where qubits share a lot of entanglement, even at large spatial distances and/or temporal separations. In the other, the system is weakly connected, so correlations like entanglement decay quickly with distance or time. These are the two phases that we probed in our experiment. The strongly entangled phase enables teleportation, which occurs when the state of one qubit is instantly transmitted, or “teleported,” to another far away qubit by measuring all but those two qubits.

Question: How did you control when a phase transition occurred

Khemani: The competing forces at play are the interactions between qubits, which tend to build entanglement, and measurements of the qubits, which can destroy it. This is the famous “wave function collapse” of quantum mechanics—think of Schrödinger’s cat “collapsing” into one of two states (dead or alive) when we open the box. However, because of entanglement, the collapse is not restricted to the qubit we directly measure but affects the rest of the system too. By controlling the strength or frequency of measurements on the quantum computer, we can induce a phase transition between an entangled phase and a disentangled one.

Question: What were some of the challenges your team needed to overcome to measure quantum states, and how did you do it?

Ippoliti: Measurements in quantum mechanics are inherently random, which makes observing these phases notoriously challenging. This is because every repetition of our experiment produces a different, random-looking quantum state. This is a problem because detecting entanglement (the feature that sets our two phases apart) requires observations on many copies of the same state. To get around this difficulty, we developed a diagnostic that cross-correlates data from the quantum processor with the results of simulations on classical computers. This hybrid quantum-classical diagnostic allowed us to see evidence of the different phases on up to 70 qubits, making this one of the largest digital quantum simulations and experiments to date.

Hoke: Another challenge was that quantum experiments are currently limited by environmental noise. Entanglement is a delicate resource that is easily destroyed by interactions from the outside environment, which is the primary challenge in quantum computing. In our setup, we probe the entanglement structure between the system’s qubits, which is destroyed if the system is not perfectly isolated and instead gets entangled with the surrounding environment. We addressed this challenge by devising a diagnostic that uses noise as a feature rather than a bug—the two phases (weak and strong entanglement) respond to noise in different ways, and we used this as a probe of the phases.

Khemani: In addition, we used the fact that the “arrow of time” loses meaning with measurement-induced teleportation. This allowed us to reorganize the sequence of operations on the quantum computer in advantageous ways to mitigate the effects of noise and to devise new probes of the organization of quantum information in space-time.

Question: What do the findings mean?

Khemani: At the level of fundamental science, our experiments demonstrate new phenomena that extend our familiar concepts of “phase structure.” Instead of thinking of measurements merely as probes, we are now thinking of them as an intrinsic part of quantum dynamics, which can be used to create and manipulate novel quantum correlations. At the level of applications, using measurements to robustly generate structured entanglement is inspiring new ways to make quantum computing more robust against noise. More generally, our understanding of general phases of quantum information and dynamics is still nascent, and many exciting surprises await.

Frog pants?

How would you go about tracking these frogs?

Six images of tiny frogs wearing little plastic trackers attached to wire harnesses on their back legs.
Researchers have fitted tiny trackable radio-pants to three species of South American frogs to test their ability to navigate through the rainforest. (Submitted by Andrius Pašukonis)

You can see how tiny they are when you compare one of the frogs to a leaf visible in one of the images (top left or top right).

The answer to the question, as you may have guessed, are frog pants (or G-strings).

Sheena Goodyear’s June 13, 2023 article for the CBC’s (Canadian Broadcasting Corporation) As It Happens radio show explores the question and the research and includes an embedded 6:20 radio interview with researcher, Andrius Pašukonis,

How do you track a bunch of teeny-weeny frogs across the vast rainforests of South America? By putting teeny-weeny trackers on their teeny-weeny underwear, of course.

Biologist Andrius Pašukonis and his colleagues wanted to study the navigational capabilities of poisonous frogs that are too small for most animal tracking devices.

So he designed a Speedo-like harness that wraps around their back legs and props a tiny radio tracker on their backsides. The research team dubbed the invention “frog pants” — though Pašukonis says that’s “a bit of a misnomer.”

“My French colleagues like to call it a telemetric G-string,” Pašukonis, a senior scientist at Lithuania’s Vilnius University, told As It Happens host Nil Köksal.

“It’s a lot of fine motor skills and a lot of practice in handling tiny frogs and sewing little frog harnesses. But we go find them in the rainforest, and we catch them, and we put the tags on.”

My favourite part is “… sewing little frog harnesses.” Note: The following video features a commercial and then, moves onto a 2:22 interview,

More from Goodyear’s June 13, 2023 article, Note: A link has been removed,

Pašukonis was a PhD student at the University of Vienna when he first started experimenting with the frog pants design, and later put it to use while working as a postdoctoral fellow at Stanford University in California.

He and is colleagues used the tracker pants to study the spatial skills of three frog species that range from three to five centimetres in length — diablito poison frogs in Ecuador, and brilliant-thighed poison frogs and dyeing poison frogs in French Guiana. The findings were published late last year in the journal e-Life [sic].

“The only way to study movements of animals is to be able to track them and follow them around, which nobody has managed to do or even tried to do with these tiny, tiny frogs in the rainforest,” he said.

“So that became my goal and challenge, where I spent a good part of my PhD trying different versions of different tags and different attachment methods, trial and error, to finally get to be able to put tags on and track them and study their behaviour.”

The frogs, he admits, didn’t particularly like the pants. But they didn’t seem to mind too much, and the team removed the trackers after four to six days. 

“Like any animal, they might scratch a little bit afterwards … like a dog with a new collar,” he said. “And then they just go on with their business.”

Other scientists have tried to track tiny frogs, from Goodyear’s June 13, 2023 article, Note: Links have been removed,

The design caught the eye of Richard Essner, a biologist at Southern Illinois University Edwardsville who studies animal locomotion, and has a particular interest in little frogs.

“Tracking small frogs with radio telemetry is not an easy thing to do,” Essner, who wasn’t involved in the Stanford research, told CBC in an email. 

About a decade ago, he says his lab attempted to use radio telemetry to track the movement of the threatened Illinois chorus frog using a transmitter attached via an elastic belt around the waist.

“Unfortunately, we had to abandon the study because we found that the transmitter apparatus was interfering with locomotion. If the belt was too tight, it caused abrasion. If it was too loose it slid down around the legs and left the frog immobilized and vulnerable to predation,” he said.

The frog pants, he says, seem to offer a solution to this conundrum. 

Lea Randall, a Calgary Zoo and Wilder Institute ecologist who specializes in amphibians and reptiles, ran into similar obstacles while trying to track northern leopard frogs at a reintroduction site in B.C. 

Like the Stanford researchers, her team experimented with several different designs before landing on one that worked — a belt-like attachment with some “very stylish” smooth glass beads to prevent abrasion. 

“Unfortunately, due to the weight of the radio transmitters at the time we couldn’t study smaller individuals,” she said. 

“We didn’t use leg straps, but I can see the advantages of that to help keep the transmitters in place. The creative thinking and problem solving that goes into developing these kinds of studies always amazes me.”

Finally, frogs may be smarter than we think, from Goodyear’s June 13, 2023 article,

When it comes to animal cognition and behaviour, Pašukonis says frogs are understudied —  and he believes, underestimated — compared to birds and mammals.

The poisonous rainforest frogs, he says, may be only a few centimetres in size, but when they breed, they carry their tadpoles between 200 to 300 metres across the rainforest to find them the perfect puddle to grow in.

Then they turn right around, and make their way home again. 

“How could a little frog — frogs typically are not thought to be very smart — learn to navigate on such a big scale? And how do they find their way around more on a fundamental scientific level?” Pašukonis said.

“We’re uncovering that overall amphibians, for example, might be smarter or have more complicated cognitive abilities than we thought.”

International conference “Living Machines” dedicated to technology inspired by nature in Genoa, Italy (July 10 – 13, 2023)

I love the look and the theme for this “Living Machines” conference, which seems to be water,

A June 28, 2023 Istituto Italiano di Tecnologia (IIT) press release (also on EurekAlert) provides more detail about the conference,

Now in its twelfth year, the international conference “Living Machines”, organised by Istituto Italiano di Tecnologia (Italian Institute of Technology, IIT), returns to Italy and comes to Genoa for the first time, from 10 to 13 July. Around one hundred experts from all over the world are expected, and they will present their achievements in the field of bio-inspired science and technology. The conference will take place in an exceptional venue, the Acquario di Genova (Genoa Aquarium), which, having reached its 30th birthday, is the ideal location at which to bring together various subject areas, from biology to artificial intelligence and robotics, with a focus on sustainability and environmental protection.

The scientific organiser of the event is Barbara Mazzolai, Associate Director for Robotics and head of the Bioinspired Soft Robotics Lab at IIT, along with Fabian Meder, researcher in the Bioinspired Soft Robotics Lab group and co-chair of the conference programme.

The conference will include two events open to the public: an exhibition area, which will be accessible from 11 to 13 July in the afternoon (from 2 to 4.30 pm); and a scientific café, which will take place on the 12 July at 5 pm. The conference will be an opportunity for international guests to appreciate the region’s beauty and talents, and it will also include the participation of students from the Niccolò Paganini Conservatory of Music. In addition, a satellite event of the conference will be the ISPA – Italian Sustainability Photo Award – exhibition, which will open at Palazzo Ducale on 10 July at 6 p.m.

The “Living Machines” conference is the landmark event for the international scientific community which bases its research on living organisms, such as human beings and other animal species – terrestrial, marine, and airborne – in addition to plants, fungi, and bacteria, in order to create so-called “living machines”, in other words, forms of technology capable of replicating their structure and mechanisms of operation.

“The conference is rooted in the union between robotics and neuroscience, using man and other animal species as a model for the study of intelligence and control systems,” said Barbara Mazzolai, Associate Director for Robotics at IIT. “This year the conference will focus on the role of biomimicry in the creation of robots that are more sustainable, with applications for the challenges of environmental protection and human health. Discussions will revolve around the development of robots with a lower energy impact, made using recyclable and biodegradable materials, and that can be used in emergency situations or extreme environments, such as deep sea, soil, space, or environmental disasters, but also for precision agriculture, environmental surveillance, infrastructure monitoring, human care and medical-surgical assistance.

In the conference programme, experts will take part in a first day of parallel workshop and tutorial sessions (on 10 July), during which the topics of bioinspiration and biohybrid technology in the fields of medicine and the marine environment will be addressed. This first day will be followed by three days of plenary sessions, featuring talks by internationally-renowned scientists. More specifically: Oussama Khatib, one of the pioneers of robotics and director of the Robotics Laboratory at Stanford University; Marco Dorigo, professor at the Université Libre de Bruxelles and one of the pioneers of collective intelligence; Peter Fratzl, director of the Max Planck Institute of Colloids and Interfaces, working on research into osteoporosis and tissue regeneration; Eleni Stavrinidou, coordinator of the “Electronic Plants” group at Linköping University and an expert in bioelectronic and biohybrid systems; Olga Speck, Principal Researcher at the University of Freiburg, specialising in biomimetic materials and the regenerative capabilities of plants; and Kyu-Jin Cho, director of the Research Centre for Soft Robotics and the Biorobotics Laboratory at Seoul National University, one of the world’s leading experts on soft robotics.

For conference participants only, the programme includes: a visit to the Acquario, guided by the facility’s scientific staff, who will illustrate the work and practices needed for the protection and conservation of marine species and the undergoing research projects; an exhibition area for prototypes and products by research groups and companies operating in this field; and a dinner at Villa Lo Zerbino, with a musical contribution by students from the Niccolò Paganini Conservatory.

Open to the general public, on 12 July from 5 p.m. to 6 p.m. there will be a round table entitled “Living Machines: The Origin and the Future” chaired by science journalist Nicola Nosengo, Chief Editor of Nature Italy. Speakers will include Cecilia Laschi from the National University of Singapore, Vickie Webster-Wood from Carnegie Mellon University, Thomas Speck from the University of Freiburg and Paul Verschure from Radboud University Nijmegen.

A satellite initiative of the conference will be the exhibition for ISPA, the Italian Sustainability Photo Award, which will open at Palazzo Ducale on 10 July at 6.00 p.m. ISPA is the photographic award created by the Parallelozero agency in cooperation with the main sponsor PIMCO, to raise public awareness of environmental, social, and governance sustainability issues, encapsulated in the acronym ESG. The works of the winning photographers and finalists in the last three editions will be on display in Genoa: a selection of images that depict the emblematic stories of Italy, a nation moving towards a more sustainable future, a visual narrative that makes it easier to understand the country’s progress in research and innovation.

The organisations supporting the event include, in addition to the principal organiser Istituto Italiano di Tecnologia (Italian Institute of Technology), the international Convergent Science Network [emphasis mine], the Office of Naval Research, Radboud University Nijmegen, and the Living, Adaptive and Energy-autonomous Materials Systems Cluster of Excellence in Freiburg.

I was particularly struck by this quote, “The conference is rooted in the union between robotics and neuroscience [emphasis mine], using man and other animal species as a model for the study of intelligence and control systems,” from Barbara Mazzolai as I have an as yet unpublished post for a UNESCO neurotechnology event coming up on July 13, 2023. These events come on the heels of a May 16, 2023 Canadian Science Policy Centre panel discussion on responsible neurotechnology (see my May 12, 2023 posting).

Need to improve oversight on chimeric human-animal research

It seems chimeras are of more interest these days. In all likelihood that has something to do with the fellow who received a transplant of a pig’s heart in January 2022 (he died in March 2022).

For those who aren’t familiar with the term, a chimera is an entity with two different DNA (deoxyribonucleic acid) identities. In short, if you get a DNA sample from the heart, it’s different from a DNA sample obtained from a cheek swab. This contrasts with a hybrid such as a mule (donkey/horse) whose DNA samples show a consisted identity throughout its body.

A December 12, 2022 The Hastings Center news release (also on EurekAlert) announces a special report,

A new report on the ethics of crossing species boundaries by inserting human cells into nonhuman animals – research surrounded by debate – makes recommendations clarifying the ethical issues and calling for improved oversight of this work.

The report, “Creating Chimeric Animals — Seeking Clarity On Ethics and Oversight,” was developed by an interdisciplinary team, with funding from the National Institutes of Health. Principal investigators are Josephine Johnston and Karen Maschke, research scholars at The Hastings Center, and Insoo Hyun, director of the Center for Life Sciences and Public Learning at the Museum of Life Sciences in Boston, formerly of Case Western Reserve University.

Advances in human stem cell science and gene editing enable scientists to insert human cells more extensively and precisely into nonhuman animals, creating “chimeric” animals, embryos, and other organisms that contain a mix of human and nonhuman cells.

Many people hope that this research will yield enormous benefits, including better models of human disease, inexpensive sources of human eggs and embryos for research, and sources of tissues and organs suitable for transplantation into humans. 

But there are ethical concerns about this type of research, which raise questions such as whether the moral status of nonhuman animals is altered by the insertion of human stem cells, whether these studies should be subject to additional prohibitions or oversight, and whether this kind of research should be done at all.

The report found that:

Animal welfare is a primary ethical issue and should be a focus of ethical and policy analysis as well as the governance and oversight of chimeric research.

Chimeric studies raise the possibility of unique or novel harms resulting from the insertion and development of human stem cells in nonhuman animals, particularly when those cells develop in the brain or central nervous system.

Oversight and governance of chimeric research are siloed, and public communication is minimal. Public communication should be improved, communication between the different committees involved in oversight at each institution should be enhanced, and a national mechanism created for those involved in oversight of these studies. 

Scientists, journalists, bioethicists, and others writing about chimeric research should use precise and accessible language that clarifies rather than obscures the ethical issues at stake. The terms “chimera,” which in Greek mythology refers to a fire-breathing monster, and “humanization” are examples of ethically laden, or overly broad language to be avoided.

“The Heart’s Knowledge: Science and Empathy in the Art of Dario Robleto” from Jan. 27 to July 9, 2023 at The Block Museum of Art (Northwestern University, Chicago, Illinois)

I’m sorry to be late. Thankfully this show extends into July 2023, so, there’s still plenty of time to get to Chicago’s The Block Museum of Art (at Northwestern University) art/science exhibition. I found this on the museum’s exhibition page for “The Heart’s Knowledge: Science and Empathy in the Art of Dario Robleto” show,

What do we owe to the memories of one another’s hearts?

For American artist Dario Robleto (b. 1972), artists and scientists share a common aspiration: to increase the sensitivity of their observations. Throughout the history of scientific invention, instruments like the cardiograph and the telescope have extended the reach of perception from the tiniest stirrings of the human body to the farthest reaches of space. In his prints, sculptures, and video and sound installations, Robleto contemplates the emotional significance of these technologies, bringing us closer to the latent traces of life buried in the scientific record.

The Hearts Knowledge concentrates on the most recent decade of Robleto’s creative practice, a period of deepening engagement with histories of medicine, biomedical engineering, sound recording, and space exploration. The exhibition organizes the artist’s conceptually ambitious, elegantly wrought artworks as a series of multisensory encounters between art and science.  Each work seeks to attune viewers to the material traces of life at scales ranging from the intimate to the universal, returning always to the question: Does empathy extend beyond the boundaries of time and space?

Here’s more from a January 27, 2023 Northwestern University news release (received via email),

Exhibition searches for meaning at the limits of science and perception

“The Heart’s Knowledge: Science and Empathy in the Art of Dario Robleto” is on view Jan. 27 to July 9 [2023] at The Block Museum of Art

  • Works are informed by dialogue with Northwestern Engineering researchers during five-year residency  
  • Exhibition a tribute to NASA Golden Record creator, ‘whose heart has left the solar system’
  • Opening conversation with the artist will take place at 2 p.m. on [Saturday] Feb. 4 [2023]

American artist Dario Robleto (b. 1972) believes artists and scientists share a common aspiration: to increase the sensitivity of their observations.

From understanding the human body’s pulses and brainwaves to viewing the faintest glimmers of light from the edge of the observable universe, groundbreaking science pushes the limits of perception. Similarly, the perceptive work of artists can extend the boundaries of empathy and understanding.

Since 2018, Robleto served as an artist-at-large at the McCormick School of Engineering. This unique partnership between The Block Museum and McCormick gave the artist an open “hall pass” to learn from, collaborate with and question scientists, engineers and experts from across the University.

Robleto’s five-year residency concludes with the exhibition “The Heart’s Knowledge: Science and Empathy in the Art of Dario Robleto.” Co-presented by The Block Museum and McCormick, the exhibition is on view from Jan. 27 to July 9 [2023] at The Block Museum, 40 Arts Circle Drive on Northwestern’s Evanston campus. [emphasis mine]

A free opening conversation with the artist will take place at 2 p.m. on Saturday, Feb. 4 [2023], in Norris University Center’s McCormick Auditorium, 1999 Campus Drive in Evanston.

About the Exhibition: “The Heart’s Knowledge”

Throughout the history of scientific invention, instruments like the cardiograph and the telescope have extended the reach of perception from the tiniest stirrings of the human body to the farthest reaches of space.

Robleto’s prints, sculptures and video and sound installations contemplate the emotional significance of these technologies, bringing viewers closer to the latent traces of life buried in the scientific record.

“The Heart’s Knowledge” represents a decade of Robleto’s creative practice, from 2012 to 2022, a period marked by a deepening engagement with science, including astronomy, synthetic biology and exobiology, and a widening embrace of new materials and creative forms, from 3D-printed objects to film.

Robleto dedicates the exhibition to Ann Druyan, the creative director of NASA’s Golden Record for the Voyager 1 and 2 projects. The record includes Druyan’s brainwaves and heartbeats, recorded as she reflected on her secret love for famed astronomer and future husband Carl Sagan. The act of sneaking “love on board the Voyager” inspired Robleto to compose a love letter to the only human whose “heart has left the solar system.”

Robleto sees Druyan’s act to include her emotions on the record as the central inspiration of his work. “I consider it the greatest work of subversive, avant-garde art not yet given its due,” Robleto said. “The Golden Record and Ann’s radical act brought us all together to think about what it means to be human — to one another and to unknown beings on other worlds.”

The exhibition organizes the artist’s conceptually ambitious, elegantly wrought artworks as a series of multisensory encounters between art and science. Each asks viewers to seek out the material traces of life in scales ranging from the intimate to the universal, and to question: Does empathy extend beyond the boundaries of time and space?

“Whether he’s addressing the most minute phenomena of the body or the horizons of the known universe, Robleto binds the rigor of scientific inquiry with artistic expression,” said exhibition curator Michael Metzger, The Block’s Pick-Laudati Curator of Media Arts.

“Straining at the bounds of observation, Robleto discovers unity at the limits; the common endeavor of art and science to achieve a form of knowledge that language alone cannot speak,” Metzger said.

The exhibition includes three sections:

Heartbeats
Rooted in the artist’s longstanding fascination with the clinical and cultural history of the human heart, “Heartbeats” draws inspiration from 19th-century pioneers of cardiography, whose instruments graphically measured heart activity for the first time, leaving behind poignant records of human subjectivity. In “The First Time, the Heart (A Portrait of Life 1854-1913)” (2017), Robleto transforms early measurements of heartbeats into photolithographs executed on paper hand-sooted with candle flames. For the installation “The Pulse Armed with a Pen (An Unknown History of the Human Heartbeat)” (2014), Robleto collaborated with sound historian Patrick Feaster to digitally resurrect these heartbeats in audio form, giving visitors access to intimate pulses of life recorded before the invention of sound playback.

Wavelengths
Robleto has recently embraced digital video to create works that narrate transformational episodes in the recording and study of wave phenomena. “Wavelengths” comprises two hour-long immersive video installations. “The Boundary of Life is Quietly Crossed” (2019) is inspired by NASA’s Voyager Golden Record, a gold-plated phonographic disc launched into space onboard the Voyager I and II space probes in 1977. In “The Aorta of an Archivist” (2020-2021), Robleto investigates three breakthroughs in the history of recording: the first recording of a choral performance made with an Edison wax cylinder, the first heartbeat captured while listening to music and the first effort to transcribe the brain wave activity of a dreaming subject.

Horizons
In the final section, “Horizons,” Robleto evokes the spirit of the Hubble telescope and the search for extraterrestrial life, gazing out at the boundaries of the observable universe. Inspired by his time as an artist-in-residence at the SETI Institute (Search for Extraterrestrial Intelligence) and as artistic consultant to the Breakthrough Initiatives, his intricate sculptures, such as “Small Crafts on Sisyphean Seas” (2018), give shape to the speculative search for intelligent life in the universe. Other works like “The Computer of Jupiter” (2019) are framed as “gifts for extraterrestrials” offering an alternative view of the best way to begin a dialogue with alien intelligences.

The Artist-at-Large Program at Northwestern

Lisa Corrin, the Ellen Philips Katz Executive Director of The Block Museum of Art, and Julio M. Ottino, dean of McCormick School of Engineering, envisioned the possibilities of this unconventional partnership between scientist and artist when they launched the artist-at-large initiative together. The work is part of an ongoing Art + Engineering initiative and a part of the whole-brain engineering philosophy at Northwestern Engineering.

“Here, a university’s school of engineering and its art museum come together in the shared belief that transformative innovation can happen at the intersections of usually distinct academic disciplines and modes of creativity and inquiry,” Corrin said. “We had faith that something meaningful would emerge organically if we merely provided structures in which informal interactions might take place.”

“We wanted to model for young engineers the value of embracing uncertainty as part of the journey that leads to innovation and opens pathways within the imagination — as artists do,” Ottino said. “We are grateful to Dario Robleto for accepting our invitation to come to Northwestern and to enter the unknown with us. He has taught us that our shared future resides in our capacity for compassion and for empathy, the ethos at the heart of his work that holds the most promise for those at the forefront of science in the interest of humankind.”

More information about Robleto’s residency can be found in the article “Dario is our Socrates” on the Block Museum website and by viewing the Northwestern Engineering video “Artist-at-Large Program: Dario Robleto.”

Exhibition Events

“The Heart’s Knowledge” will include six months of events and dialogues that will illuminate the intersections in Robleto’s practice. All events are free and open to the public. For current program information, visit The Block Museum website.
