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 [...]
