Chemists have known how to use electricity to split water into hydrogen and oxygen for more than 200 years. Nonetheless, because the electrochemical route is inefficient, most of the hydrogen made nowadays comes from natural gas. Seh et al. review recent progress in electrocatalyst development to accelerate water-splitting, the reverse reactions that underlie fuel cells, and related oxygen, nitrogen, and carbon dioxide reductions.

First-row, earth-abundant metals offer an inexpensive and sustainable alternative to precious-metal catalysts. As such, iron and cobalt catalysts have garnered interest as replacements for alkene and alkyne hydrofunctionalization reactions. However, these have required the use of air- and moisture-sensitive catalysts and reagents, limiting both adoption by the non-expert as well as applicability, particularly in industrial settings.

A team of scientists has compositionally modified magnetite to capture visible sunlight and convert this light energy into electrical current. This current may be useful to drive the decomposition of water into hydrogen and oxygen. The team generated this material by replacing one third of the iron atoms with chromium atoms. The team is from Pacific Northwest National Laboratory (PNNL) and includes researchers from EMSL, the Environmental Molecular Sciences Laboratory, a DOE Office of Science user facility, and Argonne National Laboratory.

President Trump ordered a mandatory freeze on a wide range of pending Obama administration rules over the weekend ... The freeze could have an immediate effect on a number of non-final rules from agencies like the Department of Agriculture, the Department of Energy, U.S. EPA, the Department of Transportation, among others, according to federal records.

A team led by University of Washington’s David Baker in collaboration with researchers at the U.S. Department of Energy Joint Genome Institute (DOE JGI) has reported that structural models have been generated for hundreds of protein families that had previously had no structural information available.

Pairing two catalysts in a single, illuminated reaction flask proves to be a light-bulb moment for organic synthesis. The light from a standard electric light bulb is the key to a simple, green version of the C-H activation reaction, and as researchers at KAUST have shown, this is one of the hottest new reactions for assembling complicated chemical structures.

US President Donald Trump is fond of taking pokes at China, but the anti-China message doesn’t seem to have gotten through to the Department of Energy. Last week the agency took in a 5 million [dollar] donation that will help ensure that the heart of a climate change research collaboration between the US and China keeps beating.

Ronke Olabisi once dreamed of becoming an astronaut. Now she’s conducting research that could help space travelers and Earth-dwellers heal faster and stay healthy. "If healing people faster on Earth is going to be helpful, then it’s really going to be helpful in space," said Olabisi, an assistant professor in Rutgers’ Department of Biomedical Engineering. "Spaceflight affects every single system."

Stanford researchers are collaborating to create nanoparticles that emit light in response to a force stimulus. They hope to use these nanoparticles as sensors to study the miniscule, previously ignored forces governing many biological processes. Currently, they are testing these sensors in the digestive systems of millimeter-long worms called nematodes.

Tiny drones could scout high-rise buildings and underground tunnels for possible threats to US troops in cities of the future. But instead of spending years cooking up the necessary drone technologies in military research labs, the Pentagon might be better off shopping for the latest civilian drones coming soon to stores.

To move the needle on workforce health, employers need to establish and maintain comprehensive, multi-component, evidence-based health promotion programs that improve organizational health (discussed below) alongside individual health. So, how does an employer build a culture of health that is broader than any individual wellness program component?

A late-night drive-thru, a quick stop on a road trip, busy families with little time to exercise. Obesity has become an epidemic - especially in the United States, where the convenience of food and lack of time often outweigh healthy habits. What qualifies a person as being "obese?"

Brian Nosek had pretty much given up on finding a funder. For two years he had sent out grant proposals for his software project. ... Like a number of up-and-coming researchers in his generation, Nosek was troubled by mounting evidence that science itself-through its systems of publication, funding, and advancement-had become biased toward generating a certain kind of finding: novel, attention grabbing, but ultimately unreliable.
