Scientists have used ultrafast high-intensity lasers to superheat gold to 14 times its melting point without turning the solid metal into a liquid. The record-breaking experiment, which was described in a study published July 23 in the journal Nature, smashed a decades-old theory about the stability of solids and is the first reliable method to precisely measure the temperature of …

Linda Hogan has spoken out following the death of her ex-husband, Hulk Hogan, on Thursday. Responding to an Instagram post she initially shared on July 19, when she reminisced about the “good old days,” Linda said Monday, “It’s so hard to know he’s just gone.” “I had no idea he would pass away this soon,” Linda, 65, wrote. “We all …

Gold remains perfectly solid when briefly heated beyond previously hypothesized limits, a new study reports, which may mean a complete reevaluation of how matter behaves under extreme conditions. The international team of scientists behind the study used intense, super-short laser blasts to push thin fragments of gold past a limit known as the entropy catastrophe; the point at which a …

Credit: Greg Stewart/SLAC National Accelerator Laboratory It’s not easy to surprise physicists with a phase change. Yet when Tom White first reviewed the data from a new experiment that used lasers to heat gold, he had to pause and double-check his results. He had good reason to be skeptical. White and his colleagues had just observed solid gold reaching an …

Researchers have been able to heat up a sample of solid gold to over 14 times its melting temperature for a fraction of a second, bypassing a theoretical limit known as the entropy catastrophe. The approach, known as superheating, might lead to a better understanding of how substances change phase at a fundamental level and even to improved production of …

Scientists are warning that glaciers melting due to global warming could trigger explosive — and potentially deadly — volcanic eruptions around the world. As detailed in a new study presented at the Goldschmidt international geochemistry conference this week and due to be peer-reviewed later this year, researchers from the University of Wisconsin-Madison analyzed six volcanoes in southern Chile to study …

The effects of climate change could awaken hundreds of volcanoes worldwide – which in turn could worsen the effects of climate change. According to recent models predicting changes in the magma beneath Patagonia’s glaciers, the retreat of ice has the power to shake subglacial volcanoes out of their slumber. The world isn’t at imminent risk of volcanic bombardment, but the …
