Physicists have directly measured a long- predicted quantum phase acquired when an atomic wave packet falls freely under gravity while a second part remains stationary relative to Earth. The measured phase matches the prediction obtained...

Cosmic star formation has fallen by a factor of about 2.46 over the past 4.5 billion years, but the density of neutral atomic hydrogen has declined far less. FAST and DESI observations of roughly 2.5 million galaxies show that...
LUX- ZEPLIN recorded one high- energy nuclear recoil that researchers have not been able to match convincingly to known detector backgrounds. The event has a global statistical significance of 2.6 sigma, intriguing enough for...
