It’s always questionable to blog about something that is gaining attention because it’s illegal, but that’s the case with the latest crop of articles about open access in popular media.  While the scientific community has been debating the merits of open access for a while now, the business behind scientific publishing is getting a lot more attention lately because of Alexandra Elbakyan, a graduate student from Kazakhstan who has hacked into hundreds of scholarly journals.

Elbakayn leaked millions of documents, opening a (albeit illegal) door for the public to freely access just about every scientific paper ever published.

To some, Elbakyan is a hero – taking a stand for the public’s right to know. To others, she is a criminal.

“Realistically only scientists at really big, well-funded universities in the developed world have full access to published research,” said Michael Eisen, a professor at the University of California, Berkeley, and a longtime champion of open access. “The current system slows science by slowing communication of work, slows it by limiting the number of people who can access information and quashes the ability to do the kind of data analysis” that is possible when articles aren’t “sitting on various siloed databases.”

This from The New York Times:

Journal publishers collectively earned $10 billion last year, much of it from research libraries, which pay annual subscription fees ranging from $2,000 to $35,000 per title if they don’t buy subscriptions of bundled titles, which cost millions. The largest companies, like Elsevier, Taylor & Francis, Springer and Wiley, typically have profit margins of over 30 percent.

A recent pistachio recall is bringing Salmonella and other foodborne illnesses back into the national spotlight. The popularity of the in-shell pistachio brands recalled paired with the long shelf-life of the nut has health experts concerned for the potential of the foodborne illness to spread rapidly. Many are again asking: how can we better control food safety?

Shin Horikawa and his team at Auburn University believe their novel biosensor technology could resolve many of the current issues surrounding the spread of foodborne illnesses. As the principal scientist for a concept hand-picked for the FDA’s Food Safety Challenge, Horikawa is looking to make pathogen detection faster, more specific, and cheaper.

Faster, cheaper, smarter

“The current technology to detect Salmonella takes a really long time, from a few days to weeks. Our first priority is to shorten this detection time. That’s why we came up with a biosensor-based detection method,” Horikawa, Postdoctoral researcher at Auburn University and member of ECS, says.

Horikawa and his team’s concept revolves around the placement of a tiny biosensor—a sensor so small that it’s nearly invisible to the human eye—on the surface of fresh fruits and vegetables to detect the presence of pathogenic organisms such as Salmonella. This on-site, robust detection method utilizes magnetoelastic (ME) materials that can change their shape when a magnetic field is applied. The materials respond differently to each magnetic field, changing their shapes accordingly. This allows the researchers to detect if a specific pathogen—such as Salmonella—has attached to the biosensor.

Here at ECS, we love at things science, technology, engineering, and math. With that said, it’s only fitting that we pay a little homage to everyone’s favorite mathematical constant on its name day.

Pi is an irrational and transcendental number, continuing infinitely without repetition or pattern. It’s been calculated our as far as over one trillion digits beyond its decimal point, with Japanese memory master Akira Haraguchi having recited the first 100,000 digits of Pi in public. (However, we only need 39 digits of Pi to be able to measure the circumference of the observable universe, but we won’t tell him that.)

So what happens on Pi Day (aside from math enthusiasts around the world uniting)? Well, the San Francisco-based museum that started the celebration throws an annual party, MIT will let you know if you made their acceptance cut, and you can probably find local pizza shops that will give you a discount.

And don’t forget, Pi Day also coincides with Albert Einstein’s birthday (he’d be 137 years old today).

Celebrate today by learning more about Pi!

Together with his team, ECS member Wolfgang Schuhmann develops new electrodes, for the production of hydrogen.

New research out of Ruhr Universitaet Bochum is showing big gains for water electrolysis, with new efficiency levels double that of previous efforts.

By applying a layer of copper atoms in conventional platinum electrodes, researchers were able to desorption easier for the catalyst surface. This system then generated twice the amount of hydrogen than a platinum electrode without a copper layer.

This breakthrough could help water electrolysis gain a better reputation as a method for hydrogen production. Prior to this breakthrough, too much energy was lost in the process to prove it efficient. Now, the efficiency level has been doubled.

This from Ruhr Universitaet Bochum:

The researchers modified the properties of the platinum catalyst surface by applying a layer of copper atoms. With this additional layer, the system generated twice the amount of hydrogen than with a pure platinum electrode. But only if the researchers applied the copper layer directly under the top layer of the platinum atoms. The group observed another useful side effect: the copper layer extended the service life of the electrodes, for example by rendering them more corrosion-resistant.

“To date, hydrogen has been mainly obtained from fossil fuels, with large CO2 volumes being released in the process,” said Wolfgang Schuhmann, ECS member and lead author of the study. “If we succeeded in obtaining hydrogen by using electrolysis instead, it would be a huge step towards climate-friendly energy conversion. For this purpose, we could utilize surplus electricity, for example generated by wind power.”

Measuring the pH level of a solution is usually a relatively simple process. However, that process begins to get more complicated as things get smaller.

Examining changes in acidity or alkalinity at the nanoscale, for example, has been a nearly impossible feat for researchers. Now, a team from the Polish Academy of Sciences in Warsaw, including 11 year ECS member Gunter Wittstock, has developed a novel method of pH measurement at the nanoscale.

The group has developed a nanosensor with the ability to continuously monitor changes in pH levels.

This from the Polish Academy of Sciences in Warsaw:

Used as a scanning electrochemical microscope probe, it allows for the precise measurement of changes in acidity/alkalinity occurring over very small fragments of the surface of a sample immersed in a solution. The spatial resolution here is just 50 nm, and in the future, it can be reduced even further.

Read the full article.

“The ability to monitor changes in the acidity or alkalinity of solutions at the nanoscale, and thus over areas whose dimensions can be counted in billionths of a meter, is an important step toward better understanding of many chemical processes. The most obvious examples here are various kinds of catalytic reactions or pitting corrosion, which begins on very small fragments of a surface,” said Marcin Opallo, lead author in the study.

The team hopes that this new method could lead to monitoring of pH changes taking place in the vicinity of individual chemical molecules.

Nikola Tesla is undoubtedly one of the most recognizable scientists in history, unfortunately much of his groundbreaking research lived in the shadows for the majority of his life. His pioneering contributions to science included alternating current, hydroelectricity, cryogenic engineering, the remote control, neon lighting, and wireless communication just to name a few.

While Tesla may have died around 30 years before the first call made made via a wireless cellphone, his advances in science helped make that reality achievable.

The statue is the brainchild of Dorrian Porter, and entrepreneur that finds likeness with Tesla in that they were both immigrant that found scientific success in the U.S.

“This unique project… is also intended to inspire the entrepreneurs who come to the Silicon Valley to think big and selflessly—as Tesla did,” says Porter. “The free exchange of information and affordable access to sustainable energy have the potential to solve the critical issues of poverty and education, and inspire peace.”
