River buries permafrost carbon at sea

A new study found that Arctic rivers, such as the Mackenzie River, are responsible for burying large amounts of organic carbon from thawing permafrost at sea. This process locks away carbon dioxide and helps stabilize the earth's CO2 levels over time, providing a potential natural sink for excess greenhouse gas emissions.

Gastric bypass surgery lowers women's alcohol tolerance

A new study published in JAMA Surgery found that gastric bypass surgery can alter how the body metabolizes alcohol, leading to higher and more rapid blood-alcohol levels. Women who underwent the surgery experienced changes similar to those seen in men, with a significant increase in blood-alcohol content after consuming just two drinks.
