18,000-year-old shelter may be the oldest evidence of human occupation in the Americas
Archaeologists have unearthed the oldest stone tools buried under thick volcanic ash in a rock shelter in Southern Oregon in the US. The radiocarbon dating suggests that these ancient artifacts were last used roughly 18,000 years ago. The excavation work at the Rimrock Draw Rockshelter was carried out by a team of archeologists from the…

Sensors show ‘silent hazard’ is swelling the ground beneath cities by up to 12mm
For the first time, scientists have quantified the effects of a silent hazard known as ‘underground heat islands’ beneath major global cities, according to new research published in Nature Communications Engineering on July 11. While the study highlights long-term damage to structures, it also sees an opportunity to capture underground waste heat— using geothermal technologies— as an…

James Webb Space Telescope examines massive kilonova explosion for first time
When two neutron stars crash together, they produce a big and bright explosion known as a kilonova. A neutron star is the condensed remnant of incredibly massive stars that have undergone gravitational collapse. The orbiting neutron stars collide at tremendous speeds, and in this process emit gamma-ray bursts (GRBs), which are brief bursts of extremely…
