Loss of the Y chromosome in aging men is widespread and increasingly linked to serious diseases, challenging assumptions that the Y has little biological importance beyond sex determination. As men age, some of their cells gradually lose the Y chromosome. For a long time, researchers assumed this change had little medical importance because the Y [...]
A rare massive star system is producing something far smaller than expected. New data from NASA’s James Webb Space Telescope reveal what astronomers did not see coming.
Hundreds of millions of animals are killed on our roads each year. Now, scientists have revealed how these deaths could play an unexpected role advancing wildlife science and conservation.

Scientists have built a massive cellular atlas showing how aging reshapes the body across 21 organs. Studying nearly 7 million cells, they found that aging starts earlier than expected and unfolds in a coordinated way throughout the body. About a quarter of cell types change in number over time, and many of these shifts differ between males and females. The research also highlights shared genetic “hotspots” that could become targets for anti-aging therapies.
