Researchers at Weill Cornell Medicine and Birkbeck, University of London, have identified a site where a commonly used anesthetic binds to sodium ion channels, revealing a molecular mechanism that may explain how these drugs dampen communication between neurons. Ion channels are

Skeletal muscles—responsible for movement, joint stabilization and postural support—are highly metabolically active and heavily reliant on oxygen during physical activity. However, conditions such as high-intensity exercise or sustained exertion frequently expose skeletal muscles

Dietary supplements must be better regulated to protect public health, says the American College of Physicians (ACP). In a new paper, "Modernizing the Regulatory Framework for Dietary Supplements: A Position Paper from the American College of Physicians" published today in Annals

Up to 4,000 community banks fear looming legislation to regulate digital cash will deprive rural firms and farmers of $850bn-worth of loansOn a quiet summer morning, above a small mid-western town, an American flag is waving in the breeze. The camera cuts to a father helping his

Exercise doesn't just make the heart stronger. It also rewires the nerves that regulate it, a discovery that could pave the way for more personalized treatments for common heart conditions such as arrhythmias and angina.

For decades, scientists thought royal jelly was the secret ingredient that turned an ordinary honeybee larva into a queen. New research reveals the process is far more remarkable: young worker bees create special “royal cribs” made from customized wax, carefully regulate warmth a

For decades, the rivers of the Murray-Darling Basin have been heavily regulated by dams and irrigation networks. As a result, the volume of water entering the ocean is about 60% smaller than 100 years ago. But nature broke through during massive floods over the summer of 2022–23,

Microscopic plankton are among the most important organisms on Earth. Phytoplankton produce around half of the oxygen we breathe, while plankton as a whole underpin marine food webs, support fisheries, help regulate carbon and sustain life across the ocean.

A new study published in the Proceedings of the National Academy of Sciences has offered insight into how Staphylococcus aureus, a major human pathogen, fine-tunes its internal machinery to survive stress and potentially cause infection. The research uncovers new details about th

Plants need nitrogen to grow. Many legumes meet this need through a symbiotic relationship: They harbor bacteria that fix atmospheric nitrogen and make it available to the plant. Until now, it was largely unclear how a perennial plant regulates this symbiosis without destroying i
