Do Earth-like exoplanets have magnetic fields? Far-off radio signal is promising sign
Earth's magnetic field does more than keep everyone's compass needles pointed in the same direction. It also helps preserve Earth's sliver of life-sustaining atmosphere by deflecting high energy particles and plasma regularly blasted out of the sun......»»
Biologists develop new record bright red fluorescent protein
To understand why a cell divides, secretes hormones or transmits a signal to another cell, biologists often use a trick. They attach colored lights to the proteins of interest, so that they can follow the movements and interactions of those proteins.....»»
The search for the missing gravitational signal
Every year, hundreds of thousands of pairs of black holes merge in a cosmic dance that emits gravitational waves in every direction. Since 2015, the large ground-based LIGO, Virgo and KAGRA interferometers have made it possible to detect these signal.....»»
