Some benefits of exercise stem from the immune system
Research in mice shows that the anti-inflammatory properties of exercise may arise from immune cells mobilized to counter exercise-induced inflammation. Immune cells prevent muscle damage by lowering levels of interferon, a key driver of chronic inflam…
Seeing the unseen: How butterflies can help scientists detect cancer
There are many creatures on our planet with more advanced senses than humans. Turtles can sense Earth’s magnetic field. Mantis shrimp can detect polarized light. Elephants can hear much lower frequencies than humans can. Butterflies can perceive a broa…
Milestone moment toward development of nuclear clock
Physicists have started the countdown on developing a new generation of timepieces capable of shattering records by providing accuracy of up to one second in 300 billion years, or about 22 times the age of the universe.
Scientists map loss of groundwater storage around the world
Global water resources are stretched by climate change and human population growth, and farms and cities are increasingly turning to groundwater to fill their needs. Unfortunately, the pumping of groundwater can cause the ground surface above to sink, …
