Tiny silver catalysts work differently when solid oxide cells generate electricity and when they produce hydrogen, revealing a potential route to more efficient clean energy systems. Solid oxide cells can generate electricity or use electricity to split water and produce hydrogen. Silver nanocatalysts, tiny silver particles that speed up chemical reactions, can improve their performance [...]

An experiment comparing falling and stationary rubidium atomic waves found a quantum phase difference consistent with Einstein’s equivalence principle. A rubidium atom can behave as a wave that researchers can split between two paths. This allows the same atom to effectively follow both paths at once, without being broken into pieces. Physicists have now used [...]

The findings offer new insights that could help guide the development of future therapies. A protein called human resistin may help flip on one of the immune system’s most powerful inflammatory switches. Researchers at Johns Hopkins Medicine found that resistin can activate a pathway involved in chronic inflammation, a process linked to conditions including cardiovascular [...]

The study reveals the biology behind why the disease appeared so different after spreading to cows and offers a framework for recognizing new forms of the disease more quickly. H5N1 bird flu caused severe infections in cows’ udders while largely sparing their lungs when it began spreading among U.S. dairy cattle in early 2024. That [...]

Hair thinning reported with Ozempic-like drugs may not be explained by rapid weight loss alone, as a new genetic study points to the GLP-1 pathway itself. Hair thinning reported by people taking drugs such as Ozempic, Wegovy, and Zepbound has often been attributed to the rapid weight loss these medications can produce. A new genetic [...]
