A foundational chemistry concept found in textbooks for almost 100 years may have been taught incorrectly. Researchers say the inductive effect in neutral molecules appears to extend only across one chemical bond, rather than gradually weakening over ...

A wearable device has revealed nighttime hormone surges that may expose a frequently missed cause of high blood pressure. The discovery could help explain why primary aldosteronism often escapes standard blood tests and point toward a more accurate . ...

Captive-raised saltwater crocodiles released into Bangladesh's Sundarbans surprised scientists by settling into the wild rather than trying to return to their breeding facility. The result suggests that releasing larger, mature captive crocodiles ...

A World War I submarine wreck off Denmark is leaking TNT into the surrounding water, seabed, and marine life more than a century after it sank. Scientists warn that thousands of similar wrecks could pose growing environmental risks as they continue . ...

Low vitamin D levels may make recovery from breast cancer surgery more painful, according to a study of 184 women undergoing mastectomy. Patients with vitamin D deficiency were three times more likely to experience moderate to severe pain during the ...

Scientists discovered that aging cells can use malfunctioning mitochondria to unlock inflammatory genes and keep the immune system stuck in a prolonged state of alert. Blocking one part of this process reduced inflammation and improved healthy aging ...

Mount Etna's ancient eruptions followed radically different paths, with some magma lingering near the surface for weeks while other magma raced upward from nearly 30 kilometers deep in just hours. Scientists traced the difference to volcanic gases .. ...

Scientists have found that Arctic cyclones become especially destructive when several strike one after another. These storm clusters cause about twice as much sea ice loss as isolated cyclones, with impacts that persist roughly two and a half times . ...

Sucralose, the artificial sweetener used in Splenda, came under scrutiny after a study found that a related chemical damaged DNA and weakened the gut barrier in laboratory experiments. But later findings have complicated that alarming picture.

Scientists found that the 3D organization of DNA is disrupted in several types of brain cells affected by Alzheimer's disease, altering how important genes are switched on and off. The discovery reveals a previously underexplored layer of the disease ...
