Scientists discovered a hidden gut-brain network that can change cravings when the body needs more protein. The body has a remarkable ability to recognize when it is missing important nutrients and adjust behavior accordingly. New research shows that the gut plays a much larger role in this process than previously understood, actively detecting protein shortages [...]

Scientists discovered that Antarctica’s ice sheet became dramatically more climate-sensitive after crossing a critical threshold one million years ago. A new study published in Nature Geoscience suggests that Antarctica’s massive ice sheet underwent a major change about one million years ago, becoming far more responsive to shifts in Earth’s climate. The research, led by scientists [...]

A newly discovered molecule disrupts cancer cells’ ability to repair DNA by triggering the breakdown of key proteins. Cancer cells can survive by repairing damage to their DNA—even damage that would normally be fatal. A key defense mechanism is homologous recombination, a highly accurate repair process that fixes broken DNA using proteins such as RAD51 [...]
