Hubble has captured a spectacular view of LH 95, where about 2,500 young stars are still on their journey to becoming full-fledged stars. Scientists discovered these growing stars can keep pulling in gas and dust for millions of years, extending an important stage of stellar deve
Mini monitor measures artificial heartbeat
An international team, including the University of Tokyo, has created a sensor inspired by the lateral line in fish—their "sixth sense" organ—which measures the pulse of lab-grown 3D heart tissue (cardiac organoids). The device, called a biomechanical well plate, looks like a sma

The galaxy’s coldest “stars” may actually be alien megastructures
Scientists have identified new clues that could help astronomers spot one of the most famous hypothetical alien megastructures: a Dyson sphere. The study finds that red dwarfs and white dwarfs are the most promising stars to examine, since advanced civilizations could potentially
