American Association for the Advancement of Science 2016 Mass Media Fellows program is open for submissions

Before getting to the latest information for applying, Matt Miller has written an exuberant and enticing  description of his experiences as a 2016 American Association for the Advancement of Science (AAAS) Mass Media Fellow for Slate.com in his Oct. 17, 2016 article for them (Note: Links have been removed),

If you’ve ever wanted to write for Slate (or other major media organizations), now is your chance—provided you’re a graduate student or postdoc in science, math, engineering, or medicine [enrolled in a university and with a US citizenship or visa that allows you to receive paymet for work].* The American Association for the Advancement of Science will soon be opening applications for its 2017 Mass Media Fellowship. Along with Slate, publications like Wired, Scientific American, NPR [National Public Radio], and the Los Angeles Times will be hosting fellows who will work as science writers for 10 weeks starting in June of next year.

..

While many of my classmates were drawing blood and administering vaccines [Miller is a student in a School of Veterinary Medicine], I flew up to New York and started learning how to be a journalist. In Slate’s Brooklyn office, I read the abstracts of newly released journal articles and pitched countless story ideas. I drank lots of coffee, sat in on editorial meetings, and interviewed scientists from almost every field imaginable (entomologists are the best). Perhaps the highlight of the whole summer was being among the first to cover the rising cost of EpiPens, a scandal that has recently led to a congressional hearing.

A large part of what I did this summer involved explaining the scientific fundamentals behind the research and making the findings more accessible and exciting to a general audience. Science writing involves a great deal of translation; scientists often get so tied up in the particulars of their research—exactly how an enzyme cleaves this protein, or whether a newly discovered bird is technically a new species—that they forget to talk about the wider societal implications their research might have on culture and civilization. But science writing also matters for the same reason all journalism matters. Science journalism can play the important role of watchdog, holding the powerful accountable and airing out things that don’t quite seem right.

You can find the application here. Don’t forget to read the eligibility rules (no students enrolled in English, journalism, science journalism, or other non-technical fields need apply).

Good luck!

Café Scientifique (Vancouver, Canada) October 18, 2016 talk: At the intersection of Space and Genetics

Vancouver’s (Canada) Café Scientifique seems to have settled in at Yagger’s Downtown (433 W. Pender), which is hosting (for the third time in four months) an upcoming 2016 Café Scientifique talk. From the October 17, 2016 notice received via email,

We are pleased to announce that this month’s event will be a collaboration with the American Society of Human Genetics (ASHG).  The café will be held tomorrow (Tuesday October 18th) at 7:30pm in the back room at Yagger’s Downtown, 433 W Pender.  Please note that this date is one week earlier than usual to coincide with the ASHG Annual Meeting.  Our speaker for the evening will be Dr. Ting Wu, from the Department of Genetics at Harvard Medical School. The title of her talk is:

At the intersection of Space and Genetics

Ting (C.-ting) Wu, Ph.D., is a Professor of Genetics at Harvard Medical School. She is also the Director of the Consortium for Space Genetics, the Director of the Personal Genetics Education (pgEd.org) Project, and a recipient of an NIH Director’s Pioneer Award. Her laboratory investigates how chromosome organization influences genome function, inventing and applying technologies for imaging the genome as well as studying how a very puzzling set of sequences, called ultraconserved elements (UCEs), have managed to resist change for a stunning 300 million years. These studies have led her group to consider the potential of their findings for protecting astronauts from the extreme conditions of long-term travel in space. The Wu laboratory also houses the Personal Genetics Education Project, which works to raise public awareness and discourse regarding personal genetics, aiming to make that awareness equal across all communities, regardless of socioeconomic, ethnic, educational, and religious influences.

Have a lovely time!

Phenomen: a future and emerging information technology project

A Sept. 19, 2016 news item on Nanowerk describes a new research project incorporating photonics, phononics, and radio frequency signal processing,

HENOMEN is a ground breaking project designed to harness the potential of combined phononics, photonics and radio-frequency (RF) electronic signals to lay the foundations of a new information technology. This new Project, funded though the highly competitive H2020 [the European Union’s Horizon 2020 science funding programme] FET [Future and Emerging Technologies]-Open call, joins the efforts of three leading research institutes, three internationally recognised universities and a high-tech SME. The Consortium members kick-offed the project with a meeting on Friday September 16, 2016, at the Catalan Institute of Nanoscience and Nanotechnology (ICN2), coordinated by ICREA Research Prof Dr Clivia M. Sotomayor-Torres, of the ICN2’ Phononic and Photonic Nanostructures (P2N) Group.

A Sept. 16, 2016 ICN2 press release, which originated the news item, provides more detail,

Most information is currently transported by electrical charge (electrons) and by light (photons). Phonons are the quanta of lattice vibrations with frequencies covering a wide range up to tens of THz and provide coupling to the surrounding environment. In PHENOMEN the core of the research will be focused on phonon-based signal processing to enable on-chip synchronisation and transfer information carried between optical channels by phonons.

This ambitious prospect could serve as a future scalable platform for, e.g., hybrid information processing with phonons. To achieve it, PHENOMEN proposes to build the first practical optically-driven phonon sources and detectors including the engineering of phonon lasers to deliver coherent phonons to the rest of the chip pumped by a continuous wave optical source. It brings together interdisciplinary scientific and technology oriented partners in an early-stage research towards the development of a radically new technology.

The experimental implementation of phonons as information carriers in a chip is completely novel and of a clear foundational character. It deals with interaction and manipulation of fundamental particles and their intrinsic dual wave-particle character. Thus, it can only be possible with the participation of an interdisciplinary consortium which will create knowledge in a synergetic fashion and add value in the form of new theoretical tools,  develop novel methods to manipulate coherent phonons with light and build all-optical phononic circuits enabled by optomechanics.

The H2020 FET-Open call “Novel ideas for radically new technologies” aims to support the early stages of joint science and technology research for radically new future technological possibilities. The call is entirely non-prescriptive with regards to the nature or purpose of the technologies that are envisaged and thus targets mainly the unexpected. PHENOMEN is one of the 13 funded Research & Innovation Actions and went through a selection process with a success rate (1.4%) ten times smaller than that for an ERC grant. The retained proposals are expected to foster international collaboration in a multitude of disciplines such as robotics, nanotechnology, neuroscience, information science, biology, artificial intelligence or chemistry.

The Consortium

The PHENOMEN Consortium is made up by:

  • 3 leading research institutes:
  • 3 universities with an internationally recognised track-record in their respective areas of expertise:
  • 1 industrial partner:

Largest database of elemental crystal surfaces and shapes in the world

A Sept. 13, 2016 news item on Nanowerk describes the database,

Nanoengineers at the University of California San Diego [UCSD], in collaboration with the Materials Project at Lawrence Berkeley National Laboratory (Berkeley Lab), have created the world’s largest database of elemental crystal surfaces and shapes to date. Dubbed Crystalium, this new open-source database can help researchers design new materials for technologies in which surfaces and interfaces play an important role, such as fuel cells, catalytic converters in cars, computer microchips, nanomaterials and solid-state batteries.

A Sept. 13, 2016 UCSD news release reveals more about the goals for the database and the database itself (Note: Links have been removed),

“This work is an important starting point for studying the material surfaces and interfaces, where many novel properties can be found. We’ve developed a new resource that can be used to better understand surface science and find better materials for surface-driven technologies,” said Shyue Ping Ong, a nanoengineering professor at UC San Diego and senior author of the study.

For example, fuel cell performance is partly influenced by the reaction of molecules such as hydrogen and oxygen on the surfaces of metal catalysts. Also, interfaces between the electrodes and electrolyte in a rechargeable lithium-ion battery host a variety of chemical reactions that can limit the battery’s performance. The work in this study is useful for these applications, said Ong, who is also part of a larger effort by the UC San Diego Sustainable Power and Energy Center to design better battery materials.

“Researchers can use this database to figure out which elements or materials are more likely to be viable catalysts for processes like ammonia production or making hydrogen gas from water,” said Richard Tran, a nanoengineering PhD student in Ong’s Materials Virtual Lab and the study’s first author. Tran did this work while he was an undergraduate at UC San Diego.

The work, published Sept. 13 [2016] in the journal Scientific Data, provides the surface energies and equilibrium crystal shapes of more than 100 polymorphs of 72 elements in the periodic table. Surface energy describes the stability of a surface; it is a measure of the excess energy of atoms on the surface relative to those in the bulk material. Knowing surface energies is useful for designing materials that perform their functions primarily on their surfaces, like catalysts and nanoparticles.

The surface energies of some elements in their crystal form have been measured experimentally, but this is not a trivial task. It involves melting the crystal, measuring the resulting liquid’s surface tension at the melting temperature, then extrapolating that value back to room temperature. This process also requires that the sample have a clean surface, which is challenging because other atoms and molecules (like oxygen and water) can easily adsorb to the surface and modify the surface energy.

Surface energies obtained by this method are averaged values that lack the facet-specific resolution that is necessary for design, Ong said. “This is one of the areas where the ’virtual laboratory’ can create the most value—by allowing us to precisely control the models and conditions in a way that is extremely difficult to do in experiments.”

Also, the surface energy is not just a single number for each crystal because it depends on the crystal’s orientation. “A crystal is a regular arrangement of atoms. When you cut a crystal in different places and at different angles, you expose different facets with unique arrangements of atoms,” explained Ong, who teaches the course NANO106 – Crystallography of Materials at UC San Diego.

To carry out this ambitious project, Ong and his team developed highly sophisticated automated workflows to calculate surface energies from first principles. These workflows are built on the popular open-source Python Materials Genomics library and FireWorks workflow codes of the Materials Project, which were co-authored by Ong.

“The techniques for calculating surface energies have been known for decades. The major accomplishment is the codification of how to generate surface models and run these complex calculations in a robust and efficient manner,” Tran said. The surface model generation software code developed by the team has already been extended by others to study substrates and interfaces. Powerful supercomputers at the San Diego Supercomputer Center and the National Energy Research Scientific Computing Center at the Lawrence Berkeley National Lab were used for the calculations.

Ong’s team worked with researchers from the Berkeley Lab’s Materials Project to develop and construct Crystalium’s website. Co-founded and directed by Berkeley Lab scientist Kristin Persson, the Materials Project is a Google-like database of material properties calculated by supercomputers.

“The Materials Project was designed to be an open and accessible tool for scientists and engineers to accelerate materials innovation,” Persson said. “In five years, it has attracted more than 20,000 users working on everything from batteries to photovoltaics to thermoelectrics, and it’s extremely gratifying to see scientists like Ong providing lots of high quality computed data of high interest and making it freely available and easily accessible to the public.”

The researchers pointed out that their database is the most extensive collection of calculated surface energies for elemental crystalline solids to date. Compared to previous compilations, Crystalium contains surface energies for far more elements, including both metals and non-metals, and for more facets in each crystal. The elements that have been excluded from their calculations are gases and radioactive elements. Notably, Ong and his team have validated their calculated surface energies with those from experiments, and the values are in excellent agreement.

Moving forward, the team will work on expanding the scope of the database beyond single elements to multi-element compounds like alloys, which are made of two or more different metals, and binary oxides, which are made of oxygen and one other element. Efforts are also underway to study the effect of common adsorbates, such as hydrogen, on surface energies, which is key to understanding the stability of surfaces in aqueous media.

“As we continue to build this database, we hope that the research community will see it as a useful resource for the rational design of target surface or interfacial properties,” said Ong,

Move objects by playing a melody

At this point, moving objects by playing a melody is a laboratory experiment but who knows, perhaps one day you’ll be able to sing your front door open. A Sept. 9, 2016 news item on ScienceDaily announces the research on acoustic waves,

Researchers of Aalto University have made a breakthrough in controlling the motion of multiple objects on a vibrating plate with a single acoustic source. By playing carefully constructed melodies, the scientists can simultaneously and independently move multiple objects on the plate towards desired targets. This has enabled scientists, for instance, writing words consisting of separate letters with loose metal pieces on the plate by playing a melody.

A Sept. 9, 2016 Aalto University press release (also on EurekAlert), which originated the news item, describes the research in more detail,

Already in 1878, the first studies of sand moving on a vibrating plate were done by Ernst Chladni, known as the father of acoustics. Chladni discovered that when a plate is vibrating at a frequency, objects move towards a few positions, called the nodal lines, specific to that frequency. Since then, the prevailing view has been that the particle motion is random on the plate before they reached the nodal line. “We have shown that the motion is also predictable away from the nodal lines. Now that the object does not have to be at a nodal line, we have much more freedom in controlling its motion and have achieved independent control of up to six objects simultaneously using just one single actuator. We are very excited about the results, because this probably is a new world record of how many independent motions can be controlled by a single acoustic actuator,” says Professor Quan Zhou.

The objects to be controlled have been placed on top of a manipulation plate, and imaged by a tracking camera. Based on the detected positions, the computer goes through a list of music notes to find a note that is most likely to move the objects towards the desired directions. After playing the note, the new positions of the objects are detected, and the control cycle is restarted. This cycle is repeated until the objects have reached their desired target locations. The notes played during the control cycles form a sequence, a bit like music.

The new method has been applied to manipulate a wide range of miniature objects including electronic components, water droplets, plant seeds, candy balls and metal parts. “Some of the practical applications we foresee include conveying and sorting microelectronic chips, delivering drug-loaded particles for pharmaceutical applications or handling small liquid volumes for lab on chips,” says Zhou. “Also, the basic idea should be transferrable to other kinds of systems with vibration phenomena. For example, it should be possible to use waves and ripples to control floating objects in a pond using our technique.”

Unbreakable encrypted message with key that’s shorter than the message

A Sept. 5, 2016 University of Rochester (NY state, US) news release (also on EurekAlert), makes an intriguing announcement,

Researchers at the University of Rochester have moved beyond the theoretical in demonstrating that an unbreakable encrypted message can be sent with a key that’s far shorter than the message—the first time that has ever been done.

Until now, unbreakable encrypted messages were transmitted via a system envisioned by American mathematician Claude Shannon, considered the “father of information theory.” Shannon combined his knowledge of algebra and electrical circuitry to come up with a binary system of transmitting messages that are secure, under three conditions: the key is random, used only once, and is at least as long as the message itself.

The findings by Daniel Lum, a graduate student in physics, and John Howell, a professor of physics, have been published in the journal Physical Review A.

“Daniel’s research amounts to an important step forward, not just for encryption, but for the field of quantum data locking,” said Howell.

Quantum data locking is a method of encryption advanced by Seth Lloyd, a professor of quantum information at Massachusetts Institute of Technology, that uses photons—the smallest particles associated with light—to carry a message. Quantum data locking was thought to have limitations for securely encrypting messages, but Lloyd figured out how to make additional assumptions—namely those involving the boundary between light and matter—to make it a more secure method of sending data.  While a binary system allows for only an on or off position with each bit of information, photon waves can be altered in many more ways: the angle of tilt can be changed, the wavelength can be made longer or shorter, and the size of the amplitude can be modified. Since a photon has more variables—and there are fundamental uncertainties when it comes to quantum measurements—the quantum key for encrypting and deciphering a message can be shorter that the message itself.

Lloyd’s system remained theoretical until this year, when Lum and his team developed a device—a quantum enigma machine—that would put the theory into practice. The device takes its name from the encryption machine used by Germany during World War II, which employed a coding method that the British and Polish intelligence agencies were secretly able to crack.

Let’s assume that Alice wants to send an encrypted message to Bob. She uses the machine to generate photons that travel through free space and into a spatial light modulator (SLM) that alters the properties of the individual photons (e.g. amplitude, tilt) to properly encode the message into flat but tilted wavefronts that can be focused to unique points dictated by the tilt. But the SLM does one more thing: it distorts the shapes of the photons into random patterns, such that the wavefront is no longer flat which means it no longer has a well-defined focus. Alice and Bob both know the keys which identify the implemented scrambling operations, so Bob is able to use his own SLM to flatten the wavefront, re-focus the photons, and translate the altered properties into the distinct elements of the message.

Along with modifying the shape of the photons, Lum and the team made use of the uncertainty principle, which states that the more we know about one property of a particle, the less we know about another of its properties. Because of that, the researchers were able to securely lock in six bits of classical information using only one bit of an encryption key—an operation called data locking.

“While our device is not 100 percent secure, due to photon loss,” said Lum, “it does show that data locking in message encryption is far more than a theory.”

The ultimate goal of the quantum enigma machine is to prevent a third party—for example, someone named Eve—from intercepting and deciphering the message. A crucial principle of quantum theory is that the mere act of measuring a quantum system changes the system. As a result, Eve has only one shot at obtaining and translating the encrypted message—something that is virtually impossible, given the nearly limitless number of patterns that exist for each photon.

The paper by Lum and Howell was one of two papers published simultaneously on the same topic. The other paper, “Quantum data locking,” was from a team led by Chinese physicist Jian-Wei Pan.

“It’s highly unlikely that our free-space implementation will be useful through atmospheric conditions,” said Lum. “Instead, we have identified the use of optic fiber as a more practical route for data locking, a path Pan’s group actually started with. Regardless, the field is still in its infancy with a great deal more research needed.”

Sniffing for art conservation

The American Chemical Society (ACS) has produced a video titled, “How that ‘old book smell’ could save priceless artifacts” according to their Sept. 6, 2016 news release on EurekAlert,

Odor-detecting devices like Breathalyzers have been used for years to determine blood-alcohol levels in drunk drivers. Now, researchers are using a similar method to sniff out the rate of decay in historic art and artifacts. By tracking the chemicals in “old book smell” and similar odors, conservators can react quickly to preserve priceless art and artifacts at the first signs of decay. In this Speaking of Chemistry, Sarah Everts explains how cultural-heritage science uses the chemistry of odors to save books, vintage jewelry and even early Legos. …

Innovation and two Canadian universities

I have two news bits and both concern the Canadian universities, the University of British Columbia (UBC) and the University of Toronto (UofT).

Creative Destruction Lab – West

First, the Creative Destruction Lab, a technology commercialization effort based at UofT’s Rotman School of Management, is opening an office in the west according to a Sept. 28, 2016 UBC media release (received via email; Note: Links have been removed; this is a long media release which interestingly does not mention Joseph Schumpeter the man who developed the economic theory which he called: creative destruction),

The UBC Sauder School of Business is launching the Western Canadian version of the Creative Destruction Lab, a successful seed-stage program based at UofT’s Rotman School of Management, to help high-technology ventures driven by university research maximize their commercial impact and benefit to society.

“Creative Destruction Lab – West will provide a much-needed support system to ensure innovations formulated on British Columbia campuses can access the funding they need to scale up and grow in-province,” said Robert Helsley, Dean of the UBC Sauder School of Business. “The success our partners at Rotman have had in helping commercialize the scientific breakthroughs of Canadian talent is remarkable and is exactly what we plan to replicate at UBC Sauder.”

Between 2012 and 2016, companies from CDL’s first four years generated over $800 million in equity value. It has supported a long line of emerging startups, including computer-human interface company Thalmic Labs, which announced nearly USD $120 million in funding on September 19, one of the largest Series B financings in Canadian history.

Focusing on massively scalable high-tech startups, CDL-West will provide coaching from world-leading entrepreneurs, support from dedicated business and science faculty, and access to venture capital. While some of the ventures will originate at UBC, CDL-West will also serve the entire province and extended western region by welcoming ventures from other universities. The program will closely align with existing entrepreneurship programs across UBC, including, e@UBC and HATCH, and actively work with the BC Tech Association [also known as the BC Technology Industry Association] and other partners to offer a critical next step in the venture creation process.

“We created a model for tech venture creation that keeps startups focused on their essential business challenges and dedicated to solving them with world-class support,” said CDL Founder Ajay Agrawal, a professor at the Rotman School of Management and UBC PhD alumnus.

“By partnering with UBC Sauder, we will magnify the impact of CDL by drawing in ventures from one of the country’s other leading research universities and B.C.’s burgeoning startup scene to further build the country’s tech sector and the opportunities for job creation it provides,” said CDL Director, Rachel Harris.

CDL uses a goal-setting model to push ventures along a path toward success. Over nine months, a collective of leading entrepreneurs with experience building and scaling technology companies – called the G7 – sets targets for ventures to hit every eight weeks, with the goal of maximizing their equity-value. Along the way ventures turn to business and technology experts for strategic guidance on how to reach goals, and draw on dedicated UBC Sauder students who apply state-of the-art business skills to help companies decide which market to enter first and how.

Ventures that fail to achieve milestones – approximately 50 per cent in past cohorts – are cut from the process. Those that reach their objectives and graduate from the program attract investment from the G7, as well as other leading venture-capital firms.

Currently being assembled, the CDL-West G7 will be comprised of entrepreneurial luminaries, including Jeff Mallett, the founding President, COO and Director of Yahoo! Inc. from 1995-2002 – a company he led to $4 billion in revenues and grew from a startup to a publicly traded company whose value reached $135 billion. He is now Managing Director of Iconica Partners and Managing Partner of Mallett Sports & Entertainment, with ventures including the San Francisco Giants, AT&T Park and Mission Rock Development, Comcast Bay Area Sports Network, the San Jose Giants, Major League Soccer, Vancouver Whitecaps FC, and a variety of other sports and online ventures.

Already bearing fruit, the Creative Destruction Lab partnership will see several UBC ventures accepted into a Machine Learning Specialist Track run by Rotman’s CDL this fall. This track is designed to create a support network for enterprises focused on artificial intelligence, a research strength at UofT and Canada more generally, which has traditionally migrated to the United States for funding and commercialization. In its second year, CDL-West will launch its own specialist track in an area of strength at UBC that will draw eastern ventures west.

“This new partnership creates the kind of high impact innovation network the Government of Canada wants to encourage,” said Brandon Lee, Canada’s Consul General in San Francisco, who works to connect Canadian innovation to customers and growth capital opportunities in Silicon Valley. “By collaborating across our universities to enhance our capacity to turn the scientific discoveries into businesses in Canada, we can further advance our nation’s global competitiveness in the knowledge-based industries.”

The Creative Destruction Lab is guided by an Advisory Board, co-chaired by Vancouver-based Haig Farris, a pioneer of the Canadian venture capitalist industry, and Bill Graham, Chancellor of Trinity College at UofT and former Canadian cabinet minister.

“By partnering with Rotman, UBC Sauder will be able to scale up its support for high-tech ventures extremely quickly and with tremendous impact,” said Paul Cubbon, Leader of CDL-West and a faculty member at UBC Sauder. “CDL-West will act as a turbo booster for ventures with great ideas, but which lack the strategic roadmap and funding to make them a reality.”

CDL-West launched its competitive application process for the first round of ventures that will begin in January 2017. Interested ventures are encouraged to submit applications via the CDL website at: www.creativedestructionlab.com

It’s good to see a couple of successful (according to the news release) local entrepreneurs on the board although I’m somewhat puzzled by Mallett’s presence since, if memory serves, Yahoo! was not doing that well when he left in 2002. The company was an early success but utterly dwarfed by Google at some point in the early 2000s and these days, its stock (both financial and social) has continued to drift downwards. As for Mallett’s current successes, there is no mention of them.

Reuters Top 100 of the world’s most innovative universities

After reading or skimming through the CDL-West news you might think that the University of Toronto ranked higher than UBC on the Reuters list of the world’s most innovative universities. Before breaking the news about the Canadian rankings, here’s more about the list from a Sept, 28, 2016 Reuters news release (receive via email),

Stanford University, the Massachusetts Institute of Technology and Harvard University top the second annual Reuters Top 100 ranking of the world’s most innovative universities. The Reuters Top 100 ranking aims to identify the institutions doing the most to advance science, invent new technologies and help drive the global economy. Unlike other rankings that often rely entirely or in part on subjective surveys, the ranking uses proprietary data and analysis tools from the Intellectual Property & Science division of Thomson Reuters to examine a series of patent and research-related metrics, and get to the essence of what it means to be truly innovative.

In the fast-changing world of science and technology, if you’re not innovating, you’re falling behind. That’s one of the key findings of this year’s Reuters 100. The 2016 results show that big breakthroughs – even just one highly influential paper or patent – can drive a university way up the list, but when that discovery fades into the past, so does its ranking. Consistency is key, with truly innovative institutions putting out groundbreaking work year after year.

Stanford held fast to its first place ranking by consistently producing new patents and papers that influence researchers elsewhere in academia and in private industry. Researchers at the Massachusetts Institute of Technology (ranked #2) were behind some of the most important innovations of the past century, including the development of digital computers and the completion of the Human Genome Project. Harvard University (ranked #3), is the oldest institution of higher education in the United States, and has produced 47 Nobel laureates over the course of its 380-year history.

Some universities saw significant movement up the list, including, most notably, the University of Chicago, which jumped from #71 last year to #47 in 2016. Other list-climbers include the Netherlands’ Delft University of Technology (#73 to #44) and South Korea’s Sungkyunkwan University (#66 to #46).

The United States continues to dominate the list, with 46 universities in the top 100; Japan is once again the second best performing country, with nine universities. France and South Korea are tied in third, each with eight. Germany has seven ranked universities; the United Kingdom has five; Switzerland, Belgium and Israel have three; Denmark, China and Canada have two; and the Netherlands and Singapore each have one.

You can find the rankings here (scroll down about 75% of the way) and for the impatient, the University of British Columbia ranked 50th and the University of Toronto 57th.

The biggest surprise for me was that China, like Canada, had two universities on the list. I imagine that will change as China continues its quest for science and innovation dominance. Given how they tout their innovation prowess, I had one other surprise, the University of Waterloo’s absence.

Scientific evidence and certainty: a controversy in the US Justice system

It seems that forensic evidence does not deliver the certainty that television and US prosecutors (I wonder if Canadian Crown Attorneys or Crown Counsels concur with their US colleagues?) would have us believe. The US President’s Council of Advisors on Science and Technology (PCAST) released a report (‘Forensic Science in Criminal Courts: Ensuring Scientific Validity of Feature-Comparison Methods‘ 174 pp PDF) on Sept. 20, 2016 that amongst other findings, notes that more scientific rigour needs to be applied to the field of forensic science.

Here’s more from the Sept. 20, 2016 posting by Eric Lander, William Press, S. James Gates, Jr., Susan L. Graham, J. Michael McQuade, and Daniel Schrag, on the White House blog,

The study that led to the report was a response to the President’s question to his PCAST in 2015, as to whether there are additional steps on the scientific side, beyond those already taken by the Administration in the aftermath of a highly critical 2009 National Research Council report on the state of the forensic sciences, that could help ensure the validity of forensic evidence used in the Nation’s legal system.

PCAST concluded that two important gaps warranted the group’s attention: (1) the need for clarity about the scientific standards for the validity and reliability of forensic methods and (2) the need to evaluate specific forensic methods to determine whether they have been scientifically established to be valid and reliable. The study aimed to help close these gaps for a number of forensic “feature-comparison” methods—specifically, methods for comparing DNA samples, bitemarks, latent fingerprints, firearm marks, footwear, and hair.

In the course of its year-long study, PCAST compiled and reviewed a set of more than 2,000 papers from various sources, educated itself on factual matters relating to the interaction between science and the law, and obtained input from forensic scientists and practitioners, judges, prosecutors, defense attorneys, academic researchers, criminal-justice-reform advocates, and representatives of Federal agencies.

A Sept. 23, 2016 article by Daniel Denvir for Salon.com sums up the responses from some of the institutions affected by this report,

Under fire yet again, law enforcement is fighting back. Facing heavy criticism for misconduct and abuse, prosecutors are protesting a new report from President Obama’s top scientific advisors that documents what has long been clear: much of the forensic evidence used to win convictions, including complex DNA samples and bite mark analysis, is not backed up by credible scientific research.

Although the evidence of this is clear, many in law enforcement seem terrified that keeping pseudoscience out of prosecutions will make them unwinnable. Attorney General Loretta Lynch declined to accept the report’s recommendations on the admissibility of evidence and the FBI accused the advisors of making “broad, unsupported assertions.” But the National District Attorneys Association, which represents roughly 2,5000 top prosecutors nationwide, went the furthest, taking it upon itself to, in its own words, “slam” the report.

Prosecutors’ actual problem with the report, produced by some of the nation’s leading scientists on the President’s Council of Advisors on Science and Technology, seems to be unrelated to science. Reached by phone NDAA president-elect Michael O. Freeman could not point to any specific problem with the research and accused the scientists of having an agenda against law enforcement.

“I’m a prosecutor and not a scientist,” Freeman, the County Attorney in Hennepin County, Minnesota, which encompasses Minneapolis, told Salon. “We think that there’s particular bias that exists in the folks who worked on this, and they were being highly critical of the forensic disciplines that we use in investigating and prosecuting cases.”

That response, devoid of any reference to hard science, has prompted some mockery, including from Robert Smith, Senior Research Fellow and Director of the Fair Punishment Project at Harvard Law School, who accused the NDAA of “fighting to turn America’s prosecutors into the Anti-Vaxxers, the Phrenologists, the Earth-Is-Flat Evangelists of the criminal justice world.”

It has also, however, also lent credence to a longstanding criticism that American prosecutors are more concerned with winning than in establishing a defendant’s guilt beyond a reasonable doubt.

“Prosecutors should not be concerned principally with convictions; they should be concerned with justice,” said Daniel S. Medwed, author of “Prosecution Complex: America’s Race to Convict and Its Impact on the Innocent” and a professor at Northern University School of Law, told Salon. “Using dodgy science to obtain convictions does not advance justice.”

Denvir’s article is lengthier and worth reading in its entirety.

Assuming there’s an association of forensic scientists, I find it interesting they don’t appear to have responded.

Finally, if there’s one thing you learn while writing about science it’s that there is no real certainty. For example, if you read about the Higgs boson discovery, you’ll note that the scientists involved the research never stated with absolute certainty that it exists but rather they ‘were pretty darn sure’ it does (I believe the scientific term is 5-sigma). There’s more about the Higgs boson and 5-sigma in this July 17, 2012 article by Evelyn Lamb for Scientific American,

In short, five-sigma corresponds to a p-value, or probability, of 3×10-7, or about 1 in 3.5 million. This is not the probability that the Higgs boson does or doesn’t exist; rather, it is the probability that if the particle does not exist, the data that CERN [European Particle Physics Laboratory] scientists collected in Geneva, Switzerland, would be at least as extreme as what they observed. “The reason that it’s so annoying is that people want to hear declarative statements, like ‘The probability that there’s a Higgs is 99.9 percent,’ but the real statement has an ‘if’ in there. There’s a conditional. There’s no way to remove the conditional,” says Kyle Cranmer, a physicist at New York University and member of the ATLAS team, one of the two groups that announced the new particle results in Geneva on July 4 [2012].

For the interested, there’s a lot more to Lamb’s article.

Getting back to forensic science, this PCAST report looks like an attempt to bring forensics back into line with the rest of the science world.

Teleporting photons in Calgary (Canada) is a step towards a quantum internet

Scientists at the University of Calgary (Alberta, Canada) have set a distance record for the teleportation of photons and you can see the lead scientist is very pleased.

Wolfgang Tittel, professor of physics and astronomy at the University of Calgary, and a group of PhD students have developed a new quantum key distribution (QKD) system.

Wolfgang Tittel, professor of physics and astronomy at the University of Calgary, and a group of PhD students have developed a new quantum key distribution (QKD) system.

A Sept. 21, 2016 news item on phys.org makes the announcement (Note: A link has been removed),

What if you could behave like the crew on the Starship Enterprise and teleport yourself home or anywhere else in the world? As a human, you’re probably not going to realize this any time soon; if you’re a photon, you might want to keep reading.

Through a collaboration between the University of Calgary, The City of Calgary and researchers in the United States, a group of physicists led by Wolfgang Tittel, professor in the Department of Physics and Astronomy at the University of Calgary have successfully demonstrated teleportation of a photon (an elementary particle of light) over a straight-line distance of six kilometres using The City of Calgary’s fibre optic cable infrastructure. The project began with an Urban Alliance seed grant in 2014.

This accomplishment, which set a new record for distance of transferring a quantum state by teleportation, has landed the researchers a spot in the prestigious Nature Photonics scientific journal. The finding was published back-to-back with a similar demonstration by a group of Chinese researchers.

A Sept. 20, 2016 article by Robson Fletcher for CBC (Canadian Broadcasting News) online provides a bit more insight from the lead researcher (Note: A link has been removed),

“What is remarkable about this is that this information transfer happens in what we call a disembodied manner,” said physics professor Wolfgang Tittel, whose team’s work was published this week in the journal Nature Photonics.

“Our transfer happens without any need for an object to move between these two particles.”

A Sept. 20, 2016 University of Calgary news release by Drew Scherban, which originated the news item, provides more insight into the research,

“Such a network will enable secure communication without having to worry about eavesdropping, and allow distant quantum computers to connect,” says Tittel.

Experiment draws on ‘spooky action at a distance’

The experiment is based on the entanglement property of quantum mechanics, also known as “spooky action at a distance” — a property so mysterious that not even Einstein could come to terms with it.

“Being entangled means that the two photons that form an entangled pair have properties that are linked regardless of how far the two are separated,” explains Tittel. “When one of the photons was sent over to City Hall, it remained entangled with the photon that stayed at the University of Calgary.”

Next, the photon whose state was teleported to the university was generated in a third location in Calgary and then also travelled to City Hall where it met the photon that was part of the entangled pair.

“What happened is the instantaneous and disembodied transfer of the photon’s quantum state onto the remaining photon of the entangled pair, which is the one that remained six kilometres away at the university,” says Tittel.

City’s accessible dark fibre makes research possible

The research could not be possible without access to the proper technology. One of the critical pieces of infrastructure that support quantum networking is accessible dark fibre. Dark fibre, so named because of its composition — a single optical cable with no electronics or network equipment on the alignment — doesn’t interfere with quantum technology.

The City of Calgary is building and provisioning dark fibre to enable next-generation municipal services today and for the future.

“By opening The City’s dark fibre infrastructure to the private and public sector, non-profit companies, and academia, we help enable the development of projects like quantum encryption and create opportunities for further research, innovation and economic growth in Calgary,” said Tyler Andruschak, project manager with Innovation and Collaboration at The City of Calgary.

“The university receives secure access to a small portion of our fibre optic infrastructure and The City may benefit in the future by leveraging the secure encryption keys generated out of the lab’s research to protect our critical infrastructure,” said Andruschak. In order to deliver next-generation services to Calgarians, The City has been increasing its fibre optic footprint, connecting all City buildings, facilities and assets.

Timed to within one millionth of one millionth of a second

As if teleporting a photon wasn’t challenging enough, Tittel and his team encountered a number of other roadblocks along the way.

Due to changes in the outdoor temperature, the transmission time of photons from their creation point to City Hall varied over the course of a day — the time it took the researchers to gather sufficient data to support their claim. This change meant that the two photons would not meet at City Hall.

“The challenge was to keep the photons’ arrival time synchronized to within 10 pico-seconds,” says Tittel. “That is one trillionth, or one millionth of one millionth of a second.”

Secondly, parts of their lab had to be moved to two locations in the city, which as Tittel explains was particularly tricky for the measurement station at City Hall which included state-of-the-art superconducting single-photon detectors developed by the National Institute for Standards and Technology, and NASA’s Jet Propulsion Laboratory.

“Since these detectors only work at temperatures less than one degree above absolute zero the equipment also included a compact cryostat,” said Tittel.

Milestone towards a global quantum Internet

This demonstration is arguably one of the most striking manifestations of a puzzling prediction of quantum mechanics, but it also opens the path to building a future quantum internet, the long-term goal of the Tittel group.

The Urban Alliance is a strategic research partnership between The City of Calgary and University of Calgary, created in 2007 to encourage and co-ordinate the seamless transfer of cutting-edge research between the university and The City of Calgary for the benefit of all our communities. The Urban Alliance is a prime example and vehicle for one of the three foundational commitments of the University of Calgary’s Eyes High vision to fully integrate the university with the community. The City sees the Alliance as playing a key role in realizing its long-term priorities and the imagineCALGARY vision.
