A cheap and effective new catalyst can generate hydrogen fuel from water just as efficiently as platinum, currently the best — but also most expensive — water-splitting catalyst out there.The catalyst, which is composed of nanometer-thin sheets of metal carbide, is manufactured using a self-assembly process that relies on a surprising ingredient: gelatin, the material that gives Jell-O its jiggle.
Neuroscientists have used data from the human brain connectome — a publicly available ‘wiring diagram’ of the human brain based on data from thousands of healthy human volunteers — to reassess the findings from neuroimaging studies of patients with Alzheimer’s disease.
Hundreds of dams are being proposed for Mekong River basin in Southeast Asia. The negative social and environmental consequences — affecting everything from food security to the environment — greatly outweigh the positive changes of this grand-scale flood control, according to new research.
On Nov. 26, NASA’s InSight mission knew the spacecraft touched down within an 81-mile-long (130-kilometer-long) landing ellipse on Mars. Now, the team has pinpointed InSight’s exact location using images from HiRISE, a powerful camera onboard another NASA spacecraft, Mars Reconnaissance Orbiter (MRO).
A new study found that while exercise — in this case, a 16-minute conditioning class — generally improved women’s mood and body satisfaction, women felt even better if the instructor made motivational comments that focused on strength and health instead of on losing weight or changing the appearance of one’s body.
In 1994, Chinese university student Zhu Ling began experiencing stomach pain, hair loss and partial paralysis. By the time doctors diagnosed Ling with thallium poisoning about four months later, she was in a coma. Two decades after the poisoning, mass spectrometry has been used to analyze several of Ling’s hairs collected in 1994 and 1995 and established a timeline of her poisoning.
