Cotton that glows ‘naturally’

Interesting, non? This is causing a bit of excitement but before first, here’s more from the Sept. 14, 2017 American Association for the Advancement of Science (AAAS) news release on EurekAlert,

Cotton that’s grown with molecules that endow appealing properties – like fluorescence or magnetism – may one day eliminate the need for applying chemical treatments to fabrics to achieve such qualities, a new study suggests. Applying synthetic polymers to fabrics can result in a range of appealing properties, but anything added to a fabric can get washed or worn away. Furthermore, while many fibers used in fabrics are synthetic (e.g., polyester), some consumers prefer natural fibers to avoid issues related to sensation, skin irritation, smoothness, and weight. Here, Filipe Natalio and colleagues created cotton fibers that incorporate composites with fluorescent and magnetic properties. They synthesized glucose derivatives that deliver the desirable molecules into the growing ovules of the cotton plant, Gossypium hirsutum. Thus, the molecules are embedded into the cotton fibers themselves, rather than added in the form of a chemical treatment. The resulting fibers exhibited fluorescent or magnetic properties, respectively, although they were weaker than raw fibers lacking the embedded composites, the authors report. They propose that similar techniques could be expanded to other biological systems such as bacteria, bamboo, silk, and flax – essentially opening a new era of “material farming.”

Robert Service’s Sept. 14, 2017 article for Science explores the potential of growing cotton with new properties (Note: A link has been removed),

You may have heard about smartphones and smart homes. But scientists are also designing smart clothes, textiles that can harvest energy, light up, detect pollution, and even communicate with the internet. The problem? Even when they work, these often chemically treated fabrics wear out rapidly over time. Now, researchers have figured out a way to “grow” some of these functions directly into cotton fibers. If the work holds, it could lead to stronger, lighter, and brighter textiles that don’t wear out.

Yet, as the new paper went to press today in Science, editors at the journal were made aware of mistakes in a figure in the supplemental material that prompted them to issue an Editorial Expression of Concern, at least until they receive clarification from the authors. Filipe Natalio, lead author and chemist at the Weizmann Institute of Science in Rehovot, Israel, says the mistakes were errors in the names of pigments used in control experiments, which he is working with the editors to fix.

That hasn’t dampened enthusiasm for the work. “I like this paper a lot,” says Michael Strano, a chemical engineer at the Massachusetts Institute of Technology in Cambridge. The study, he says, lays out a new way to add new functions into plants without changing their genes through genetic engineering. Those approaches face steep regulatory hurdles for widespread use. “Assuming the methods claimed are correct, that’s a big advantage,” Strano says.

Sam Lemonick’s Sept. 14, 2017 article for forbes.com describes how the researchers introduced new properties (in this case, glowing colours) into the cotton plants,

His [Filipe Natalio] team of researchers in Israel, Germany, and Austria used sugar molecules to sneak new properties into cotton. Like a Trojan horse, Natalio says. They tested the method by tagging glucose with a fluorescent dye molecule that glows green when hit with the right kind of light.

They bathed cotton ovules—the part of the plant that makes the fibers—in the glucose. And just like flowers suck up dyed water in grade school experiments, the ovules absorbed the sugar solution and piped the tagged glucose molecules to their cells. As the fibers grew, they took on a yellowish tinge—and glowed bright green under ultraviolet light.

Glowing cotton wasn’t enough for Natalio. It took his group about six months to be sure they were actually delivering the fluorescent protein into the cotton cells and not just coating the fibers in it. Once they were certain, they decided to push the envelope with something very unnatural: magnets.

This time, Natalio’s team modified glucose with the rare earth metal dysprosium, making a molecule that acts like a magnet. And just like they did with the dye, the researchers fed it to cotton ovules and ended up with fibers with magnetic properties.

Both Service and Lemonwick note that the editor of the journal Science (where the research paper was published) Jeremy Berg has written an expression of editorial concern as of Sept. 14, 2017,

In the 15 September [2017] issue, Science published the Report “Biological fabrication of cellulose fibers with tailored properties” by F. Natalio et al. (1). After the issue went to press, we became aware of errors in the labeling and/or identification of the pigments used for the control experiments detailed in figs. S1 and S2 of the supplementary materials. Science is publishing this Editorial Expression of Concern to alert our readers to this information as we await full explanation and clarification from the authors.

The problem seems to be one of terminology (from the Lemonwick article),

… Filipe Natalio, lead author and chemist at the Weizmann Institute of Science in Rehovot, Israel, says the mistakes were errors in the names of pigments used in control experiments, which he is working with the editors to fix.

These things happen. Terminology and spelling aren’t always the same from one country to the next and it can result in confusion. I’m glad to see the discussion is being held openly.

Carbon nanotubes for water desalination

In discussions about water desalination and carbon nanomaterials,  it’s graphene that’s usually mentioned these days. By contrast, scientists from the US Department of Energy’s Lawrence Livermore National Laboratory (LLNL) have turned to carbon nanotubes,

There are two news items about the work at LLNL on ScienceDaily, this first one originated by the American Association for the Advancement of Science (AAAS) offers a succinct summary of the work (from an August 24, 2017 news item on ScienceDaily,

At just the right size, carbon nanotubes can filter water with better efficiency than biological proteins, a new study reveals. The results could pave the way to new water filtration systems, at a time when demands for fresh water pose a global threat to sustainable development.

A class of biological proteins, called aquaporins, is able to effectively filter water, yet scientists have not been able to manufacture scalable systems that mimic this ability. Aquaporins usually exhibit channels for filtering water molecules at a narrow width of 0.3 nanometers, which forces the water molecules into a single-file chain.

Here, Ramya H. Tunuguntla and colleagues experimented with nanotubes of different widths to see which ones are best for filtering water. Intriguingly, they found that carbon nanotubes with a width of 0.8 nanometers outperformed aquaporins in filtering efficiency by a factor of six.

These narrow carbon nanotube porins (nCNTPs) were still slim enough to force the water molecules into a single-file chain. The researchers attribute the differences between aquaporins and nCNTPS to differences in hydrogen bonding — whereas pore-lining residues in aquaporins can donate or accept H bonds to incoming water molecules, the walls of CNTPs cannot form H bonds, permitting unimpeded water flow.

The nCNTPs in this study maintained permeability exceeding that of typical saltwater, only diminishing at very high salt concentrations. Lastly, the team found that by changing the charges at the mouth of the nanotube, they can alter the ion selectivity. This advancement is highlighted in a Perspective [in Science magazine] by Zuzanna Siwy and Francesco Fornasiero.

The second Aug. 24, 2017 news item on ScienceDaily offers a more technical  perspective,

Lawrence Livermore scientists, in collaboration with researchers at Northeastern University, have developed carbon nanotube pores that can exclude salt from seawater. The team also found that water permeability in carbon nanotubes (CNTs) with diameters smaller than a nanometer (0.8 nm) exceeds that of wider carbon nanotubes by an order of magnitude.

The nanotubes, hollow structures made of carbon atoms in a unique arrangement, are more than 50,000 times thinner than a human hair. The super smooth inner surface of the nanotube is responsible for their remarkably high water permeability, while the tiny pore size blocks larger salt ions.

There’s a rather lovely illustration for this work,

An Aug. 24, 2017 LLNL news release (also on EurekAlert), which originated the second news item, proceeds

Increasing demands for fresh water pose a global threat to sustainable development, resulting in water scarcity for 4 billion people. Current water purification technologies can benefit from the development of membranes with specialized pores that mimic highly efficient and water selective biological proteins.

“We found that carbon nanotubes with diameters smaller than a nanometer bear a key structural feature that enables enhanced transport. The narrow hydrophobic channel forces water to translocate in a single-file arrangement, a phenomenon similar to that found in the most efficient biological water transporters,” said Ramya Tunuguntla, an LLNL postdoctoral researcher and co-author of the manuscript appearing in the Aug. 24 [2017]edition of Science.

Computer simulations and experimental studies of water transport through CNTs with diameters larger than 1 nm showed enhanced water flow, but did not match the transport efficiency of biological proteins and did not separate salt efficiently, especially at higher salinities. The key breakthrough achieved by the LLNL team was to use smaller-diameter nanotubes that delivered the required boost in performance.

“These studies revealed the details of the water transport mechanism and showed that rational manipulation of these parameters can enhance pore efficiency,” said Meni Wanunu, a physics professor at Northeastern University and co-author on the study.

“Carbon nanotubes are a unique platform for studying molecular transport and nanofluidics,” said Alex Noy, LLNL principal investigator on the CNT project and a senior author on the paper. “Their sub-nanometer size, atomically smooth surfaces and similarity to cellular water transport channels make them exceptionally suited for this purpose, and it is very exciting to make a synthetic water channel that performs better than nature’s own.”

This discovery by the LLNL scientists and their colleagues has clear implications for the next generation of water purification technologies and will spur a renewed interest in development of the next generation of high-flux membranes.

Enhanced water permeability and tunable ion selectivity in subnanometer carbon nanotube porins by Ramya H. Tunuguntla, Robert Y. Henley, Yun-Chiao Yao, Tuan Anh Pham, Meni Wanunu, Aleksandr Noy. Science 25 Aug 2017: Vol. 357, Issue 6353, pp. 792-796 DOI: 10.1126/science.aan2438

And, Northeastern University issued an August 25, 2017 news release (also on EurekAlert) by Allie Nicodemo,

Earth is 70 percent water, but only a tiny portion—0.007 percent—is available to drink.

As potable water sources dwindle, global population increases every year. One potential solution to quenching the planet’s thirst is through desalinization—the process of removing salt from seawater. While tantalizing, this approach has always been too expensive and energy intensive for large-scale feasibility.

Now, researchers from Northeastern have made a discovery that could change that, making desalinization easier, faster and cheaper than ever before. In a paper published Thursday [August 24, 2017] in Science, the group describes how carbon nanotubes of a certain size act as the perfect filter for salt—the smallest and most abundant water contaminant.

Filtering water is tricky because water molecules want to stick together. The “H” in H2O is hydrogen, and hydrogen bonds are strong, requiring a lot of energy to separate. Water tends to bulk up and resist being filtered. But nanotubes do it rapidly, with ease.

A carbon nanotube is like an impossibly small rolled up sheet of paper, about a nanometer in diameter. For comparison, the diameter of a human hair is 50 to 70 micrometers—50,000 times wider. The tube’s miniscule size, exactly 0.8 nm, only allows one water molecule to pass through at a time. This single-file lineup disrupts the hydrogen bonds, so water can be pushed through the tubes at an accelerated pace, with no bulking.

“You can imagine if you’re a group of people trying to run through the hallway holding hands, it’s going to be a lot slower than running through the hallway single-file,” said co-author Meni Wanunu, associate professor of physics at Northeastern. Wanunu and post doctoral student Robert Henley collaborated with scientists at the Lawrence Livermore National Laboratory in California to conduct the research.

Scientists led by Aleksandr Noy at Lawrence Livermore discovered last year [2016] that carbon nanotubes were an ideal channel for proton transport. For this new study, Henley brought expertise and technology from Wanunu’s Nanoscale Biophysics Lab to Noy’s lab, and together they took the research one step further.

In addition to being precisely the right size for passing single water molecules, carbon nanotubes have a negative electric charge. This causes them to reject anything with the same charge, like the negative ions in salt, as well as other unwanted particles.

“While salt has a hard time passing through because of the charge, water is a neutral molecule and passes through easily,” Wanunu said. Scientists in Noy’s lab had theorized that carbon nanotubes could be designed for specific ion selectivity, but they didn’t have a reliable system of measurement. Luckily, “That’s the bread and butter of what we do in Meni’s lab,” Henley said. “It created a nice symbiotic relationship.”

“Robert brought the cutting-edge measurement and design capabilities of Wanunu’s group to my lab, and he was indispensable in developing a new platform that we used to measure the ion selectivity of the nanotubes,” Noy said.

The result is a novel system that could have major implications for the future of water security. The study showed that carbon nanotubes are better at desalinization than any other existing method— natural or man-made.

To keep their momentum going, the two labs have partnered with a leading water purification organization based in Israel. And the group was recently awarded a National Science Foundation/Binational Science Foundation grant to conduct further studies and develop water filtration platforms based on their new method. As they continue the research, the researchers hope to start programs where students can learn the latest on water filtration technology—with the goal of increasing that 0.007 percent.

As is usual in these cases there’s a fair degree of repetition but there’s always at least one nugget of new information, in this case, a link to Israel. As I noted many times, the Middle East is experiencing serious water issues. My most recent ‘water and the Middle East’ piece is an August 21, 2017 post about rainmaking at the Masdar Institute in United Arab Emirates. Approximately 50% of the way down the posting, I mention Israel and Palestine’s conflict over water.

Machine learning programs learn bias

The notion of bias in artificial intelligence (AI)/algorithms/robots is gaining prominence (links to other posts featuring algorithms and bias are at the end of this post). The latest research concerns machine learning where an artificial intelligence system trains itself with ordinary human language from the internet. From an April 13, 2017 American Association for the Advancement of Science (AAAS) news release on EurekAlert,

As artificial intelligence systems “learn” language from existing texts, they exhibit the same biases that humans do, a new study reveals. The results not only provide a tool for studying prejudicial attitudes and behavior in humans, but also emphasize how language is intimately intertwined with historical biases and cultural stereotypes. A common way to measure biases in humans is the Implicit Association Test (IAT), where subjects are asked to pair two concepts they find similar, in contrast to two concepts they find different; their response times can vary greatly, indicating how well they associated one word with another (for example, people are more likely to associate “flowers” with “pleasant,” and “insects” with “unpleasant”). Here, Aylin Caliskan and colleagues developed a similar way to measure biases in AI systems that acquire language from human texts; rather than measuring lag time, however, they used the statistical number of associations between words, analyzing roughly 2.2 million words in total. Their results demonstrate that AI systems retain biases seen in humans. For example, studies of human behavior show that the exact same resume is 50% more likely to result in an opportunity for an interview if the candidate’s name is European American rather than African-American. Indeed, the AI system was more likely to associate European American names with “pleasant” stimuli (e.g. “gift,” or “happy”). In terms of gender, the AI system also reflected human biases, where female words (e.g., “woman” and “girl”) were more associated than male words with the arts, compared to mathematics. In a related Perspective, Anthony G. Greenwald discusses these findings and how they could be used to further analyze biases in the real world.

There are more details about the research in this April 13, 2017 Princeton University news release on EurekAlert (also on ScienceDaily),

In debates over the future of artificial intelligence, many experts think of the new systems as coldly logical and objectively rational. But in a new study, researchers have demonstrated how machines can be reflections of us, their creators, in potentially problematic ways. Common machine learning programs, when trained with ordinary human language available online, can acquire cultural biases embedded in the patterns of wording, the researchers found. These biases range from the morally neutral, like a preference for flowers over insects, to the objectionable views of race and gender.

Identifying and addressing possible bias in machine learning will be critically important as we increasingly turn to computers for processing the natural language humans use to communicate, for instance in doing online text searches, image categorization and automated translations.

“Questions about fairness and bias in machine learning are tremendously important for our society,” said researcher Arvind Narayanan, an assistant professor of computer science and an affiliated faculty member at the Center for Information Technology Policy (CITP) at Princeton University, as well as an affiliate scholar at Stanford Law School’s Center for Internet and Society. “We have a situation where these artificial intelligence systems may be perpetuating historical patterns of bias that we might find socially unacceptable and which we might be trying to move away from.”

The paper, “Semantics derived automatically from language corpora contain human-like biases,” published April 14  [2017] in Science. Its lead author is Aylin Caliskan, a postdoctoral research associate and a CITP fellow at Princeton; Joanna Bryson, a reader at University of Bath, and CITP affiliate, is a coauthor.

As a touchstone for documented human biases, the study turned to the Implicit Association Test, used in numerous social psychology studies since its development at the University of Washington in the late 1990s. The test measures response times (in milliseconds) by human subjects asked to pair word concepts displayed on a computer screen. Response times are far shorter, the Implicit Association Test has repeatedly shown, when subjects are asked to pair two concepts they find similar, versus two concepts they find dissimilar.

Take flower types, like “rose” and “daisy,” and insects like “ant” and “moth.” These words can be paired with pleasant concepts, like “caress” and “love,” or unpleasant notions, like “filth” and “ugly.” People more quickly associate the flower words with pleasant concepts, and the insect terms with unpleasant ideas.

The Princeton team devised an experiment with a program where it essentially functioned like a machine learning version of the Implicit Association Test. Called GloVe, and developed by Stanford University researchers, the popular, open-source program is of the sort that a startup machine learning company might use at the heart of its product. The GloVe algorithm can represent the co-occurrence statistics of words in, say, a 10-word window of text. Words that often appear near one another have a stronger association than those words that seldom do.

The Stanford researchers turned GloVe loose on a huge trawl of contents from the World Wide Web, containing 840 billion words. Within this large sample of written human culture, Narayanan and colleagues then examined sets of so-called target words, like “programmer, engineer, scientist” and “nurse, teacher, librarian” alongside two sets of attribute words, such as “man, male” and “woman, female,” looking for evidence of the kinds of biases humans can unwittingly possess.

In the results, innocent, inoffensive biases, like for flowers over bugs, showed up, but so did examples along lines of gender and race. As it turned out, the Princeton machine learning experiment managed to replicate the broad substantiations of bias found in select Implicit Association Test studies over the years that have relied on live, human subjects.

For instance, the machine learning program associated female names more with familial attribute words, like “parents” and “wedding,” than male names. In turn, male names had stronger associations with career attributes, like “professional” and “salary.” Of course, results such as these are often just objective reflections of the true, unequal distributions of occupation types with respect to gender–like how 77 percent of computer programmers are male, according to the U.S. Bureau of Labor Statistics.

Yet this correctly distinguished bias about occupations can end up having pernicious, sexist effects. An example: when foreign languages are naively processed by machine learning programs, leading to gender-stereotyped sentences. The Turkish language uses a gender-neutral, third person pronoun, “o.” Plugged into the well-known, online translation service Google Translate, however, the Turkish sentences “o bir doktor” and “o bir hem?ire” with this gender-neutral pronoun are translated into English as “he is a doctor” and “she is a nurse.”

“This paper reiterates the important point that machine learning methods are not ‘objective’ or ‘unbiased’ just because they rely on mathematics and algorithms,” said Hanna Wallach, a senior researcher at Microsoft Research New York City, who was not involved in the study. “Rather, as long as they are trained using data from society and as long as society exhibits biases, these methods will likely reproduce these biases.”

Another objectionable example harkens back to a well-known 2004 paper by Marianne Bertrand of the University of Chicago Booth School of Business and Sendhil Mullainathan of Harvard University. The economists sent out close to 5,000 identical resumes to 1,300 job advertisements, changing only the applicants’ names to be either traditionally European American or African American. The former group was 50 percent more likely to be offered an interview than the latter. In an apparent corroboration of this bias, the new Princeton study demonstrated that a set of African American names had more unpleasantness associations than a European American set.

Computer programmers might hope to prevent cultural stereotype perpetuation through the development of explicit, mathematics-based instructions for the machine learning programs underlying AI systems. Not unlike how parents and mentors try to instill concepts of fairness and equality in children and students, coders could endeavor to make machines reflect the better angels of human nature.

“The biases that we studied in the paper are easy to overlook when designers are creating systems,” said Narayanan. “The biases and stereotypes in our society reflected in our language are complex and longstanding. Rather than trying to sanitize or eliminate them, we should treat biases as part of the language and establish an explicit way in machine learning of determining what we consider acceptable and unacceptable.”

Toronto tickets are going faster than Ottawa tickets.

I’m feeling just a bit indignant; there are not just two Canadian satellite marches as you might expect given how this notice is written up. There are 18! Eight provinces are represented with marches in Calgary (Alberta), Montréal (Québec), Prince George (British Columbia), Vancouver (British Columbia), Edmonton (Alberta), Winnipeg (Manitoba), Halifax (Nova Scotia), London (Ontario), Windsor (Ontario),  Hamilton (Ontario), Ottawa (Ontario), Toronto (Ontario), Victoria (British Columbia), Lethbridge (Alberta), St. John’s (Newfoundland and Labrador), Kitchener-Waterloo (Ontario), Sudbury (Ontario), and Saskatoon (Saskatchewan). Honestly, these folks in Ontario seem to have gotten quite insular. In any event, you can figure out how to join in by clicking here.

For those who might appreciate some cogent insight into the current science situation in the US (and an antidote to what I suspect will be a great deal of self-congratulation on these April 18, 2017 CSPC panels), there’s an April 14, 2017 article by Jason Lloyd for Slate.com (Note: Links have been removed),

The most prominent response to the situation will come April 22 [2017], as science advocates—including members of major organizations like the Union of Concerned Scientists, the American Geophysical Union, and the American Association for the Advancement of Science—“walk out of the lab and into the streets” for the first-ever March for Science. Modeled in part on January’s record-breaking Women’s March, organizers have planned a march in Washington and satellite marches in more than 400 cities across six continents. The March for Science is intended to be the largest assemblage of science advocates in history.

Too bad it will likely undermine their cause.

The goals of organizers and participants are varied and worthy, but its critics—most prominently the president himself—will smear the march as simply anti-Trump or anti-Republican partisanship. Whether that’s true is beside the point, and scientists who are keen to participate ought to do so without worrying that they’re sullying their objectivity. The many communities distressed by the actions of this administration should of course exercise their right to protest, and the March for Science may inspire deeper social and political engagement.

But participants must understand that the social and political context in which this march takes place means that it cannot produce the outcomes intended by its organizers. The officially nonpartisan march embodies in miniature the larger challenges that confront the scientific enterprise in its relationship with a society that’s undergoing profound and often distressing changes.

Let’s start by looking at what the largest representative of the scientific community, the American Association for the Advancement of Science, intends by endorsing the march. According to the AAAS’s statement of support, the march will help:

…  protect the rights of scientists to pursue and communicate their inquiries unimpeded, expand the placement of scientists throughout the government, build public policies upon scientific evidence, and support broad educational efforts to expand public understanding of the scientific process.

In other words, scientists want support for instructing—not involving—the public in the scientific process, a greater influence on policymaking, and no political accountability. That’s a pretty audacious power play, and it’s easy to see how critics might cast the march’s intent as a privileged group seeking to protect and enhance its privileges. The thing is, they wouldn’t be entirely wrong.

As science policy journalist Colin Macilwain points out in Nature, scientists and other members of the technocratic class have generally enjoyed stable, middle-class employment and society’s respect and admiration for most of the past 70 years. They have benefited from scientific and technological progress while mostly remaining insulated from the collateral damage wrought by creative destruction. Federal funding has remained generous under progressive and conservative governments and through economic booms and busts. Scientists possess a variety of relatively comfortable perches from which they can express their ideas and shape public policy.

But there are a lot of people to whom the past seven decades have not been nearly so kind. They’ve struggled to find and keep well-paying jobs in a world in which technological advancement has decoupled economic growth from employment opportunities. They’ve lost a sense of having their voices heard in policymaking, as governance and regulation becomes increasingly complex. To see a select group of people and institutions profit from this complexity has, understandably, bred resentment throughout post-industrial countries.

So what should scientists do to safeguard and support their community instead? A good first step would be to acknowledge the scope and depth of the problem. The biggest issue confronting science is not a malicious and incompetent executive, or a research enterprise that might receive less generous funding than it’s enjoyed in the past. The critical challenge—and one that will still be relevant long after Donald Trump has gone back to making poor real estate decisions—is figuring out how scientists can build an enduring relationship with all segments of the American public, so that discounting, defunding, or vilifying scientists’ important work is politically intolerable.

This does not excuse whatever appalling policies Trump will no doubt seek to implement, against which scientists should speak out forcefully in the language of public values like free speech. They did this successfully against requests for the names of Department of Energy employees who attended U.N. climate talks and the clampdown on federal agencies’ external communications. But over the longer term, scientists need to improve their connection to the public and articulate their importance to society in a way that resonates with all Americans.

Academia can also challenge the insularity of scientific practice (and not just in the sciences). Instead of an overriding focus on publishing and grants, renewed attention to teaching could train more students in academic rigor and critical appraisal of, among other things, the false claims of a populist demagogue. With research universities scattered throughout the country, academics should be incentivized to improve ties with people who might otherwise consider scientists to be condescending eggheads who only give them bad news about the climate or the economy. University medical centers and military bases provide great models for these types of strong local relationships.

Finally, scientists and technologists must also attend to the social implications of their research. This includes anticipating and mitigating the socioeconomic effects of their innovations (here’s looking at you, Silicon Valley) by allocating resources to address problems they may exacerbate, such as inequality and job loss. The high-level discussion around CRISPR, the revolutionary gene-editing technology, is a good example of both the opportunity for and difficulty of responsible innovation. This process might be made more effective by bringing the public into scientific practice and policymaking using the tools of citizen science and deliberative democracy, rather than simply telling people what scientists are doing or explaining what policymakers have already decided.

If you have the time, please read Lloyd’s piece in its entirety. The piece has certainly generated a fair number of comments (121 when I last looked).

I have run a couple of posts which feature some well-meaning advice for our southern neighbours from Canadians along with my suggestion that they might not be as helpful as we hope.

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!

Science and the 2016 US presidential campaign

An Aug. 10, 2016 American Association for the Advancement of Science (AAAS) news release (received via email and issued on behalf of ScienceDebate.org) has elicited an interesting response from David Bruggeman on his Pasco Phronesis blog. But first, here’s more about the announcement from over 50 science societies and organizations in the US regarding their list of 20 questions about science for the four 2016 US presidential candidates,

A blue-ribbon coalition of fifty-six leading U.S. nonpartisan organizations, representing more than 10 million scientists and engineers, are calling on U.S. Presidential candidates to address a set of twenty major issues in science, engineering, technology, health and the environment, and encouraging journalists and voters to press the candidates on them during the 2016 U.S. Presidential election season.

“Taken collectively, these twenty issues have at least as profound an impact on voters’ lives as those more frequently covered by journalists, including candidates’ views on economic policy, foreign policy, and faith and values,” said ScienceDebate.org chair Shawn Otto, organizer of the effort. A 2015 national poll commissioned by ScienceDebate.org and Research!America revealed that a large majority of Americans (87%) say it is important that candidates for President and Congress have a basic understanding of the science informing public policy issues.

The group crowd sourced and refined hundreds of suggestions, then submitted “the 20 most important, most immediate questions” to the Presidential campaigns of Hillary Clinton, Donald Trump, Gary Johnson, and Jill Stein, “along with an invitation to the candidates to answer them in writing and to discuss them on television,” said Otto. The questions and answers will be widely distributed to the science community, journalists, and the general public to help voters make well-informed decisions at the ballot box this November.

The list of organizations is a who’s who of the American science enterprise. “Sometimes politicians think science issues are limited to simply things like the budget for NASA or NIH, and they fail to realize that a President’s attitude toward and decisions about science and research affect the public wellbeing, from the growth of our economy, to education, to public health. Voters should have a chance to know where the Presidential candidates stand,” said Rush Holt, chief executive officer of the American Association for the Advancement of Science (AAAS) and executive publisher of the Science family of journals. “We want journalists and voters to ask these questions insistently of the candidates and their campaign staff.”

An Aug. 10, 2016 article by Brady Dennis for the Washington Post explains that while ScienceDebate.org organizers would prefer a debate they feel they are more likely to get responses to a list of questions they provide the candidates,

Climate change. Mental health. Space exploration. Vaccinations. The health of the oceans. Antibiotic-resistant superbugs.

These are not the typical meat-and-potatoes topics of presidential debates. Often, the candidates and people who ask them questions skip over such topics entirely.

But dozens of non-partisan groups that represent millions of scientists and engineers across the country are eager to change that. For the third consecutive presidential election, the folks behind ScienceDebate.org are asking candidates to hold a debate exclusively about major issues in science, engineering, health and the environment. Since that almost certainly won’t happen (it didn’t in 2008 or 2012, either), the organizers have put together 20 questions they are asking candidates to address in writing.

You can find the group’s list of 20 questions here.

As for David Bruggeman’s response, in an Aug. 11, 2016 posting on his Pasco Phronesis blog, there’s this (Note: Links have been removed),

A point of blog history worth noting – I’m no fan of ScienceDebate, so you can guess the emphasis of the writing to come.

Yesterday ScienceDebate released the questions it wants the Presidential candidates to answer.  While it still makes the motions toward an in-person debate, past experience suggests it won’t do any better than receiving answers from the campaigns.

Of course, it wouldn’t hurt if the organizers actually engaged with the Presidential Commission on Debates, which sponsors the debates (for the general election) and sets everything up several months in advance.  While I doubt they would be immediately open to having a debate focused solely on science, they might be persuaded to make those questions a significant portion of a debate focused on domestic policy.

I recommend reading David’s post in its entirety for his speculations as to why ScienceDebate has not approached the Presidential Commission on Debates. Btw, thank you David for the information about the commission on debates. It certainly changed my take on the situation.

Canadian science petition and a science diplomacy event in Ottawa on June 21, 2016*

The Canadian science policy and science funding scene is hopping these days. Canada’s Minister of Science, Kirsty Duncan, announced a new review of federal funding for fundamental science on Monday, June 13, 2016 (see my June 15, 2016 post for more details and a brief critique of the panel) and now, there’s a new Parliamentary campaign for a science advisor and a Canadian Science Policy Centre event on science diplomacy.

Petition for a science advisor

Kennedy Stewart, Canadian Member of Parliament (Burnaby South) and NDP (New Democratic Party) Science Critic, has launched a campaign for independent science advice for the government. Here’s more from a June 15, 2016 announcement (received via email),

After years of muzzling and misuse of science by the Conservatives, our scientists need lasting protections in order to finally turn the page on the lost Harper decade.

I am writing to ask your support for a new campaign calling for an independent science advisor.

While I applaud the new Liberal government for their recent promises to support science, we have a long way to go to rebuild Canada’s reputation as a global knowledge leader. As NDP Science Critic, I continue to push for renewed research funding and measures to restore scientific integrity.

Canada badly needs a new science advisor to act as a public champion for research and evidence in Ottawa. Although the Trudeau government has committed to creating a Chief Science Officer, the Minister of Science – Dr. Kirsty Duncan – has yet to state whether or not the new officer will be given real independence and a mandate protected by law.

Today, we’re launching a new parliamentary petition calling for just that: https://petitions.parl.gc.ca/en/Petition/Sign/e-415

Can you add your name right now?

Canada’s last national science advisor lacked independence from the government and was easily eliminated in 2008 after the anti-science Harper Conservatives took power.

That’s why the Minister needs to build the new CSO to last and entrench the position in legislation. Rhetoric and half-measures aren’t good enough.

Please add your voice for public science by signing our petition to the Minister of Science.

Thank you for your support,

Breakfast session on science diplomacy

One June 21, 2016 the Canadian Science Policy Centre is presenting a breakfast session on Parliament Hill in Ottawa, (from an announcement received via email),

“Science Diplomacy in the 21st Century: The Potential for Tomorrow”
Remarks by Dr. Vaughan Turekian,
Science and Technology Adviser to Secretary of State John Kerry

Event Information
Tuesday, June 21, 2016, Room 238-S, Parliament Hill
7:30am – 8:00am – Continental Breakfast
8:00am – 8:10am – Opening Remarks, MP Terry Beech
8:10am – 8:45am – Dr. Vaughan Turekian Remarks and Q&A

Dr. Turekian’s visit comes during a pivotal time as Canada is undergoing fundamental changes in numerous policy directions surrounding international affairs. With Canada’s comeback on the world stage, there is great potential for science to play an integral role in the conduct of our foreign affairs.  The United States is currently one of the leaders in science diplomacy, and as such, listening to Dr.Turekian will provide a unique perspective from the best practices of science diplomacy in the US.

Actually, Dr. Turekian’s visit comes before a North American Summit being held in Ottawa on June 29, 2016 and which has already taken a scientific turn. From a June 16, 2016 news item on phys.org,

Some 200 intellectuals, scientists and artists from around the world urged the leaders of Mexico, the United States and Canada on Wednesday to save North America’s endangered migratory Monarch butterfly.

US novelist Paul Auster, environmental activist Robert F. Kennedy Jr., Canadian poet [Canadian media usually describe her as a writer] Margaret Atwood, British writer Ali Smith and India’s women’s and children’s minister Maneka Sanjay Gandhi were among the signatories of an open letter to the three leaders.

US President Barack Obama, Canadian Prime Minister Justin Trudeau and Mexican President Enrique Pena Nieto will hold a North American summit in Ottawa on June 29 [2016].

The letter by the so-called Group of 100 calls on the three leaders to “take swift and energetic actions to preserve the Monarch’s migratory phenomenon” when they meet this month.

In 1996-1997, the butterflies covered 18.2 hectares (45 acres) of land in Mexico’s central mountains.

It fell to 0.67 hectares in 2013-2014 but rose to 4 hectares this year. Their population is measured by the territory they cover.

They usually arrive in Mexico between late October and early November and head back north in March.

Given this turn of events, I wonder how Turekian, given that he’s held his current position for less than a year, might (or might not) approach the question of Monarch butterflies and diplomacy.

I did a little research about Turekian and found this Sept. 10, 2016 news release announcing his appointment as the Science and Technology Adviser to the US Secretary of State,

On September 8, Dr. Vaughan Turekian, formerly the Chief International Officer at The American Association for the Advancement of Science (AAAS), was named the 5th Science and Technology Adviser to the Secretary of State. In this capacity, Dr. Turekian will advise the Secretary of State and the Under Secretary for Economic Growth, Energy, and the Environment on international environment, science, technology, and health matters affecting the foreign policy of the United States. Dr. Turekian will draw upon his background in atmospheric chemistry and extensive policy experience to promote science, technology, and engineering as integral components of U.S. diplomacy.

Dr. Turekian brings both technical expertise and 14 years of policy experience to the position. As former Chief International Officer for The American Association for the Advancement of Science (AAAS) and Director of AAAS’s Center for Science Diplomacy, Dr. Turekian worked to build bridges between nations based on shared scientific goals, placing special emphasis on regions where traditional political relationships are strained or do not exist. As Editor-in-Chief of Science & Diplomacy, an online quarterly publication, Dr. Turekian published original policy pieces that have served to inform international science policy recommendations. Prior to his work at AAAS, Turekian worked at the State Department as Special Assistant and Adviser to the Under Secretary for Global Affairs on issues related to sustainable development, climate change, environment, energy, science, technology, and health and as a Program Director for the Committee on Global Change Research at the National Academy of Sciences where he was study director for a White House report on climate change science.

Turekian’s last editorial for Science & Diplomacy dated June 30, 2015 features a title (Evolving Institutions for Twenty-First Century [Science] Diplomacy) bearing a resemblance to the title for his talk in Ottawa and perhaps it provides a preview (spoilers),

Over the recent decade, its treatment of science and technology issues has increased substantially, with a number of cover stories focused on topics that bridge science, technology, and foreign affairs. This thought leadership reflects a broader shift in thinking within institutions throughout the world about the importance of better integrating the communities of science and diplomacy in novel ways.

In May, a high-level committee convened by Japan’s minister of foreign affairs released fifteen recommendations for how Japan could better incorporate its scientific and technological expertise into its foreign policy. While many of the recommendations were to be predicted, including the establishment of the position of science adviser to the foreign minister, the breadth of the recommendations highlighted numerous new ways Japan could leverage science to meet its foreign policy objectives. The report itself marks a turning point for an institution looking to upgrade its ability to meet and shape the challenges of this still young century.

On the other side of the Pacific, the U.S. National Academy of Sciences released its own assessment of science in the U.S. Department of State. Their report, “Diplomacy for the 21st Century: Embedding a Culture of Science and Technology Throughout the Department of State,” builds on its landmark 1999 report, which, among other things, established the position of science and technology adviser to the secretary of state. The twenty-seven recommendations in the new report are wide ranging, but as a whole speak to the fact that while one of the oldest U.S. institutions of government has made much progress toward becoming more scientifically and technologically literate, there are many more steps that could be taken to leverage science and technology as a key element of U.S. foreign policy.

These two recent reports highlight the importance of foreign ministries as vital instruments of science diplomacy. These agencies of foreign affairs, like their counterparts around the world, are often viewed as conservative and somewhat inflexible institutions focused on stability rather than transformation. However, they are adjusting to a world in which developments in science and technology move rapidly and affect relationships and interactions at bilateral, regional, and global scales.

At the same time that some traditional national instruments of diplomacy are evolving to better incorporate science, international science institutions are also evolving to meet the diplomatic and foreign policy drivers of this more technical century. …

It’s an interesting read and I’m glad to see the mention of Japan in his article. I’d like to see Canadian science advice and policy initiatives take more notice of the rest of the world rather than focusing almost solely on what’s happening in the US and Great Britain (see my June 15, 2016 post for an example of what I mean). On another note, it was disconcerting to find out that Turekian believes that we are only now moving past the Cold War politics of the past.

Unfortunately for anyone wanting to attend the talk, ticket sales have ended even though they were supposed to be open until June 17, 2016. And, there doesn’t seem to be a wait list.

You may want to try arriving at the door and hoping that people have cancelled or fail to arrive therefore acquiring a ticket. Should you be an MP (Member of Parliament), Senator, or guest of the Canadian Science Policy Conference, you get a free ticket. Should you be anyone else, expect to pay $15, assuming no one is attempting to scalp (sell one for more than it cost) these tickets.

*’ … on June’ in headline changed to ‘ … on June 21, 2016’ on June 17, 2016.

Science (magazine) investigates Sci-Hub (a pirate site for scientific papers)

Sci-Hub, a pirate website for scientific papers, and its progenitor, Alexandra Elbakyan, have generated a couple of articles and an editorial in Science magazine’s latest issue (April 28, 2016?). An April 29, 2016 article by Bob Yirka for phys.org describes one of the articles (Note: Links have been removed),

A correspondent for the Science family of journals has published an investigative piece in Science on Sci-Hub, a website that illegally publishes scholarly literature, i.e. research papers. In his article, John Bohannon describes how he made contact with Alexandra Elbakyan, the founder of what is now the world’s largest site for pirated scholarly articles, data she gave him, and commentary on what was revealed. Bohannon has also published another piece focused exclusively on Elbakyan, describing her as a frustrated science student. Marcia McNutt, Editor-in-Chief of the Science Family also weighs in on her “love-hate” relationship with Sci-Hub, and explains in detail why she believes the site is likely to cause problems for scholarly publishing heading into the future.

An April 28, 2016 American Association for the Advancement of Science (AAAS) news release provides some detail about the number of downloads from the Sci-Hub site,

In this investigative news piece from Science, contributing correspondent John Bohannon dives into data from Sci-Hub, the world’s largest pirate website for scholarly literature. For the first time, basic questions about Sci-Hub’s millions of users can be answered: Where are they and what are they reading? Bohannon’s statistical analysis is based on server log data supplied by Alexandra Elbakyan herself, the neuroscientist who created Sci-Hub in 2011. After establishing contact with her through an encrypted chat system, Bohannon and Elbakyan worked together to create a data set for public release: 28 million Sci-Hub download requests going back to 1 September 2015, including the digital object identifier (DOI) for every paper and the clustered locations of users based on their Internet Protocol address. In his story, Bohannon reveals that Sci-Hub usage is highest in China with 4.4 million download requests over the 6-month period, followed by India and Iran. But Sci-Hub users are not limited to the developing world, he reports; the U.S. is the fifth largest downloader and some of the most intense Sci-Hub activity seems to be happening on US and European university campuses, supporting the claim that many users could be accessing the papers through their libraries, but turn to Sci-Hub for convenience.

Bohanon’s piece appears to be open access. Here’s a link and a citation,

Who’s downloading pirated papers? Everyone by John Bohannon. Science (2016). DOI: 10.1126/science.aaf5664 Published April 28, 2016.

Comments

The analysis of the data is fascinating but I’m not sure why this is being billed as an ‘investigative’ piece. Generally speaking I would expect an investigative piece to unearth new information which has likely been hidden. At the very least, I would expect some juicy inside information (i.e., gossip).

Bohannon certainly had no difficulty getting information (from the April 28, 2016 Science article),

For someone denounced as a criminal by powerful corporations and scholarly societies, Elbakyan was surprisingly forthcoming and transparent. After establishing contact through an encrypted chat system, she worked with me over the course of several weeks to create a data set for public release: every download event over the 6-month period starting 1 September 2015, including the digital object identifier (DOI) for every paper. To protect the privacy of Sci-Hub users, we agreed that she would first aggregate users’ geographic locations to the nearest city using data from Google Maps; no identifying internet protocol (IP) addresses were given to me. (The data set and details on how it was analyzed are freely accessible)

Why would it be surprising that someone who has made a point of freeing scientific research and making it accessible also makes the data from her Sci-Hub site freely available? The action certainly seems consistent with her raison d’être.

Bohannon steers away from making any serious criticisms of the current publishing régimes although he does mention a few bones of contention while laying them to rest, more or less. This is no great surprise since he’s writing for one of the ‘big three’, a journal that could be described as having a vested interest in maintaining the status quo. (For those who are unaware, there are three journal considered the most prestigious or high impact for scientific studies: Nature, Cell, and Science.)

Characterizing Elbakyan as a ‘frustrated’ student in an April 28, 2016 profile by John Bohannon (The frustrated science student behind Sci-Hub) seems a bit dismissive. Sci-Hub may have been borne of frustration but it is an extraordinary accomplishment.

The piece has resulted in at least one very irate librarian, John Dupuis, from an April 29, 2016 posting on his Confessions of a Science Librarian blog,

Overall, the articles are pretty good descriptions of the Sci-Hub phenomenon and relatively even-handed [emphasis mine], especially coming from one of the big society publishers like AAAS.

There was one bit in the main article, Who’s downloading pirated papers? Everyone, that really stuck in my craw. Basically, Sci-Hub — and all that article piracy — is librarians’ fault.

And for all the researchers at Western universities who use Sci-Hub instead, the anonymous publisher lays the blame on librarians for not making their online systems easier to use and educating their researchers. “I don’t think the issue is access—it’s the perception that access is difficult,” he says.

Fortunately it was countered, in the true “give both sides of the story” style of mainstream journalism, by another quote, this time from a librarian.

“I don’t agree,” says Ivy Anderson, the director of collections for the California Digital Library in Oakland, which provides journal access to the 240,000 researchers of the University of California system. The authentication systems that university researchers must use to read subscription journals from off campus, and even sometimes on campus with personal computers, “are there to enforce publisher restrictions,” she says.

But of course, I couldn’t let it go. Anderson’s response is perfectly fine but somehow there just wasn’t enough rage and exasperation in it. So I stewed about it over night and tweeted up a tweetstorm of rage this morning, with the idea that if the rant was well-received I would capture the text as part of a blog post.

As you may have guessed by my previous comments, I didn’t find the article quite as even-handed as Dupuis did. As for the offence to librarians, I did notice but it seems in line with the rest of the piece which dismisses, downplays, and offloads a few serious criticisms while ignoring how significant issues (problematic peer review process,  charging exorbitant rates for access to publicly funded research, failure to adequately tag published papers that are under review after serious concerns are raised, failure to respond in a timely fashion when serious concerns are raised about a published paper, positive publication bias, …) have spawned the open access movement and also Sci-Hub. When you consider that governments rely on bibliometric data such as number of papers published and number of papers published in high impact journals (such as one of the ‘big three’), it’s clear there’s a great deal at stake.

Other Sci-Hub pieces here

My last piece about Sci-Hub was a February 25, 2016 posting titled,’ Using copyright to shut down easy access to scientific research‘ featuring some of the discussion around Elsevier and its legal suite against Sci-Hub.

NISE Net, the acronym remains the same but the name changes

NISE Net, the US Nanoscale Informal Science Education Network is winding down the nano and refocussing on STEM (science, technology, engineering, and mathematics). In short, NISE Net will now stand for National Informal STEM Education Network. Here’s more from the Jan. 7, 2016 NISE Net announcement in the January 2016 issue of the Nano Bite,

COMMUNITY NEWS

NISE Network is Transitioning to the National Informal STEM Education Network

Thank you for all the great work you have done over the past decade. It has opened up totally new possibilities for the decade ahead.

We are excited to let you know that with the completion of NSF funding for the Nanoscale Informal Science Education Network, and the soon-to-be-announced NASA [US National Aeronautics and Space Administration]-funded Space and Earth Informal STEM Education project, the NISE Network is transitioning to a new, ongoing identity as the National Informal STEM Education Network! While we’ll still be known as the NISE Net, network partners will now engage audiences across the United States in a range of STEM topics. Several new projects are already underway and others are in discussion for the future.

Current NISE Net projects include:

  • The original Nanoscale Informal Science Education Network (NISE Net), focusing on nanoscale science, engineering, and technology (funded by NSF and led by the Museum of Science, Boston)
  • Building with Biology, focusing on synthetic biology (funded by NSF and led by the Museum of Science with AAAS [American Association for the Advancement of Science], BioBuilder, and SynBerc [emphases mine])
  • Sustainability in Science Museums (funded by Walton Sustainability Solutions Initiatives and led by Arizona State University)
  • Transmedia Museum, focusing on science and society issues raised by Mary Shelley’s Frankenstein (funded by NSF and led by Arizona State University)
  • Space and Earth Informal STEM Education (funded by NASA and led by the Science Museum of Minnesota)

The “new” NISE Net will be led by the Science Museum of Minnesota in collaboration with the Museum of Science and Arizona State University. Network leadership, infrastructure, and participating organizations will include existing Network partners, and others attracted to the new topics. We will be in touch through the newsletter, blog, and website in the coming months to share more about our plans for the Network and its projects.

In the mean time, work is continuing with partners within the Nanoscale Informal Science Education Network throughout 2016, with an award end date of February 28, 2017. Although there will not be a new NanoDays 2016 kit, we encourage our partners to continue to engage audiences in nano by hosting NanoDays events in 2016 (March 26 – April 3) and in the years ahead using their existing kit materials. The Network will continue to host and update nisenet.org and the online catalog that includes 627 products of which 366 are NISE Net products (public and professional), 261 are Linked products, and 55 are Evaluation and Research reports. The Evaluation and Research team is continuing to work on final Network reports, and the Museum and Community Partnerships project has awarded 100 Explore Science physical kits to partners to create new or expanded collaborations with local community organizations to reach new underserved audiences not currently engaged in nano. These collaborative projects are taking place spring-summer 2016.

Thank you again for making this possible through your great work.

Best regards,

As noted in previous posts, I’m quite interested in the synthetic biology focus the network has established in the last several months starting in late Spring 2015 and the mention of two (new-to-me) organizations, BioBuilder and Synberc piqued my interest.

I found this on the About the foundation page of the BioBuilder website,

What’s the best way to solve today’s health problems? Or hunger challenges? Address climate change concerns? Or keep the environment cleaner? These are big questions. And everyone can be part of the solutions. Everyone. Middle school students, teens, high school teachers.

At BioBuilder, we teach problem solving.
We bring current science to the classroom.
We engage our students to become real scientists — the problem solvers who will change the world.
At BioBuilder, we empower educators to be agents of educational reform by reconnecting teachers all across the country with their love of teaching and their own love of learning.

Synthetic biology programs living cells to tackle today’s challenges. Biofuels, safer foods, anti-malarial drugs, less toxic cancer treatment, biodegradable adhesives — all fuel young students’ imaginations. At BioBuilder, we empower students to tackle these big questions. BioBuilder’s curricula and teacher training capitalize on students’ need to know, to explore and to be part of solving real world problems. Developed by an award winning team out of MIT [Massachusetts Institute of Technology], BioBuilder is taught in schools across the country and supported by thought leaders in the STEM community.

BioBuilder proves that learning by doing works. And inspires.

As for Synberc, it is the Synthetic Biology Engineering Research Center and they has this to say about themselves on their About us page (Note: Links have been removed),

Synberc is a multi-university research center established in 2006 with a grant from the National Science Foundation (NSF) to help lay the foundation for synthetic biology Our mission is threefold:

develop the foundational understanding and technologies to build biological components and assemble them into integrated systems to accomplish many particular tasks;
train a new cadre of engineers who will specialize in engineering biology; and
engage the public about the opportunities and challenges of engineering biology.

Just as electrical engineers have made it possible for us to assemble computers from standardized parts (hard drives, memory cards, motherboards, and so on), we envision a day when biological engineers will be able to systematically assemble biological components such as sensors, signals, pathways, and logic gates in order to build bio-based systems that solve real-world problems in health, energy, and the environment.

In our work, we apply engineering principles to biology to develop tools that improve how fast — and how well — we can go through the design-test-build cycle. These include smart fermentation organisms that can sense their environment and adjust accordingly, and multiplex automated genome engineering, or MAGE, designed for large-scale programming and evolution of cells. We also pursue the discovery of applications that can lead to significant public benefit, such as synthetic artemisinin [emphasis mine], an anti-malaria drug that costs less and is more effective than the current plant-derived treatment.

The reference to ‘synthetic artemisinin’ caught my eye as I wrote an April 12, 2013 posting featuring this “… anti-malaria drug …” and the claim that the synthetic “… costs less and is more effective than the current plant-derived treatment” wasn’t quite the conclusion journalist, Brendan Borrell arrived at. Perhaps there’s been new research? If so, please let me know.
