Astronomers report the discovery of a new ultra-metal-poor star as part of the Southern Photometric Local Universe Survey (S-PLUS). The newly found star, designated SPLUS J210428.01−004934.2, turns out to have the lowest ...
As the size of modern technology shrinks down to the nanoscale, weird quantum effects—such as quantum tunneling, superposition, and entanglement—become prominent. This opens the door to a new era of quantum technologies, ...

An international team of astronomers reports the detection of a new planetary system by observing a nearby star known as HD 18599 (or TOI-179). It appears that this star is orbited by a Neptune-mass exoplanet and a massive ...
An experiment outlined by a UCL (University College London)-led team of scientists from the UK and India could test whether relatively large masses have a quantum nature, resolving the question of whether quantum mechanical ...
