Toxic “forever chemicals” found in 95% of beers tested in the U.S.

Leave a Comment / News / By

Forever chemicals known as PFAS have turned up in an unexpected place: beer. Researchers tested 23 different beers from across the U.S. and found that 95% contained PFAS, with the highest concentrations showing up in regions with known water contamination. The findings reveal how pollution in municipal water supplies can infiltrate popular products, raising concerns …

These dinosaur eggs survived 85 million years. What they reveal is wild

Leave a Comment / News / By

Dating dinosaur eggs has always been tricky because traditional methods rely on surrounding rocks or minerals that may have shifted over time. Now, for the first time, scientists have directly dated dinosaur eggs by firing lasers at tiny eggshell fragments. The technique revealed that fossils in central China are about 85 million years old, placing …

Strange “heavy” electrons could be the future of quantum computing

Leave a Comment / Technology / By

Scientists in Japan have uncovered a strange new behavior in “heavy” electrons — particles that act as if they carry far more mass than usual. These electrons were found to be entangled, sharing a deep quantum link, and doing so in ways tied to the fastest possible time in physics. Even more surprising, the effect …
