Earthquakes create a spark in quartz that can form massive gold nuggetsScientists have figured out why up to 75 per cent of all the gold ever mined forms inside quartz in areas with a long history of earthquakes. Chris Voisey, a Canadian geologist at Monash University in Australia, said he was trying to solve how gold arose inside quartz. In his study in the journal Nature Geoscience, he found that earthquake stress on quartz crystals generates an electrical voltage that causes dissolved gold to precipitate into a solid that can grow into the largest nuggets ever found.Ice Age Teens went through puberty just like today’s kidsA new analysis of the bones of teenagers from 25,000 years ago shows they experienced puberty in much the same way as teens today. An international team of researchers including Paleolithic archaeologist April Nowell analyzed the bones of 13 teens found across Europe, and by looking at particular markers in the bones, they were able to see which stage of puberty the teens were in when the
