The latest discoveries were made by Webb's Mid-Infrared Instrument (MIRI) instrument as part of the James Webb Observations of Young ProtoStars (JOYS+) program and revealed key chemical ingredients astronomers are looking for in the search for distant worlds that could be home to life.Given that they are young protostars, IRAS 2A and IRAS 23385 do not appear to have planets in orbits around them yet. However, the detections of organic molecules around them are promising indicators for regions of future habitability.Along with the detection of ethanol, MIRI has also detected what astronomers believe is probably acetic acid, an ingredient commonly...

Monkeys in modern-day Thai forests create stone artifacts uncannily similar to those crafted by early humans — challenging the established narrative of human cultural evolution. A new study published on Friday in Science Advances suggests the possibility that a critical hallmark of human tool use happened by accident — potentially blurring the line between tool use by early humans and our primate relatives. - snip - In an abandoned oil palm plantation on a national park site, the monkeys would create nut-cracking ‘stations’ beneath the feral trees. There they break open the palm fruit’s oil-rich pit between hand-wielded hammer rocks...

Marine archaeologists began studying the 39-foot-long vessel—nicknamed the "Zambratija boat" because of its location in the Bay of Zambratija—after hearing reports from local fishermen in 2008. Researchers were surprised to learn the vessel dated to between the 12th and 10th centuries B.C.E, which they say makes it the oldest entirely hand-sewn boat in the Mediterranean.Workers painstakingly constructed the vessel by using flexible fibers to stitch together pieces of wood. While that technique was popular around the world both before and after the introduction of metal components, researchers say the Zambratija boat is unique because it's a rare surviving example of...
