Archaeologists associate the site with the Gravettian culture, hunter-gatherers known for their Venus figurines.In 2021, researchers found a toolkit consisting of 29 blades and bladelets grouped together as if once wrapped in animal skin. The collection included spear points, scrapers, drills, and blanks for making additional tools. Some had been sharpened or repaired, and the materials — including flint, chert, and even one piece of opal — came from as far as 50 to 80 miles away.“Normally when they find tools, they’re scattered — one here, one there,” said Johnson, Radio Catskill’s resident science contributor. “These were all together in a group, like somebody set down their kit and never picked it back up.”For archaeologists, the find offers more than cultural context; it offers a glimpse of one individual’s life 30 millennia ago. “The fact that these things were found together and likely from one person connects us to an individual,” Johnson said. “That gives us some insight into what life may have been like 30,000 years ago.”New Hydrogel May Boost FarmingA second story, published in June in the American Chemical Society’s Agricultural Science and Technology Journal, highlights a new hydrogel developed at the Italian Institute of Technology in Genoa.Hydrogels are water-absorbing polymers already used in...","thumbnail_url":"https://img.transistorcdn.com/q7XXsnSXT_u4mZLCn3chUorwDmUD_kWiB272D6emB18/rs:fill:0:0:1/w:400/h:400/q:60/mb:500000/aHR0cHM6Ly9pbWct/dXBsb2FkLXByb2R1/Y3Rpb24udHJhbnNp/c3Rvci5mbS80N2Uy/OGY5MWUwZThkYTEw/NDVkZGM2ZGZkZDIw/ZjliOS5wbmc.webp","thumbnail_width":300,"thumbnail_height":300}
