Scientists are taking a closer look at the pill forms of Wegovy and Ozempic. In an animal study, the ingredient SNAC, which helps semaglutide survive the stomach and enter the bloodstream, was associated with changes in gut bacteria, inflammation ...

Scientists have built a massive cellular atlas showing how aging reshapes the body across 21 organs. Studying nearly 7 million cells, they found that aging starts earlier than expected and unfolds in a coordinated way throughout the body. About a ...

Drug-resistant bacteria are becoming harder to treat, pushing scientists to look for new antibiotic targets. Researchers have now discovered that several unrelated viruses disable a key bacterial protein called MurJ, which is essential for building . ...

Scientists at Texas A&M are turning an everyday pick-me-up into a high-tech medical switch. By combining caffeine with CRISPR gene editing, researchers have created a system that allows cells to be programmed in advance -- and then activated simply . ...

Researchers found that cutting two amino acids common in animal protein--methionine and cysteine--made mice burn significantly more energy. The boost in heat production was nearly as powerful as constant exposure to cold temperatures. The mice didn't ...

Researchers at Nagoya University have created a more efficient iron-based photocatalyst that could reduce the need for rare and expensive metals in advanced chemistry. Unlike earlier designs, the new catalyst uses far fewer costly chiral ligands ...

Scientists have unveiled a breakthrough way to turn natural gas--long burned as fuel--into valuable chemical building blocks for medicines and other high-demand products. By designing a clever iron-based catalyst powered by LED light, researchers ...

Heart disease is on track to tighten its grip on American women. New projections from the American Heart Association warn that over the next 25 years, cardiovascular disease will rise sharply, driven largely by a surge in high blood pressure, ...

A massive study of more than 270,000 people has uncovered a surprising link between a common amino acid and how long men live. Researchers found that higher levels of tyrosine--an amino acid found in protein-rich foods and often marketed as a focus . ...

Biomolecular condensates were long believed to be simple liquid blobs inside cells. Researchers have now uncovered that some are actually supported by fine protein filaments forming an internal scaffold. When this structure is disrupted, cells fail . ...
