Virginia Tech researchers are investigating how overloaded mitochondria in the brain’s memory circuits may spark early Alzheimer’s damage. Their work focuses on calcium signaling and how it might trigger breakdowns in the entorhinal cortex. ​Virginia Tech researchers are investigating how overloaded mitochondria in the brain’s memory circuits may spark early Alzheimer’s damage.

Scientists at the University of Pennsylvania have shown for the first time that it’s possible to detect dormant cancer cells in breast cancer survivors and eliminate them with repurposed drugs, potentially preventing recurrence. In a clinical trial, existing medications cleared these hidden cells in most participants, leading to survival rates above 90%. The findings open …

Snowfall shortages are now destabilizing some of the world’s last resilient glaciers, as shown by a new study in Tajikistan’s Pamir Mountains. Using a monitoring station on Kyzylsu Glacier, researchers discovered that stability ended around 2018, when snowfall declined sharply and melt accelerated. The work sheds light on the Pamir-Karakoram Anomaly, where glaciers had resisted …
