Deadliest Period in Earth’s History Was Also the Stinkiest – Toxic Microbe Burps Caused Mass Extinction

Volcanos Mass Extinction

Volcanos in present-day Siberia kickstarted the world’s biggest mass extinction event. Tiny microbes belching toxic gas helped cause — and prolong — the biggest mass extinction in Earth’s history, a new study suggests. Generally, scientists believe Siberian volcanos spitting greenhouse gases primarily drove the mass extinction event about 250 million years ago, at the end … Read more

Himalayan Glaciers Melting at “Exceptional Rate” – Water Supply for Millions of People Threatened

Khumbu Glacier tongue. Credit: Duncan Quincey, University of Leeds The accelerating melting of the Himalayan glaciers threatens the water supply of millions of people in Asia, new research warns. The study, led by the University of Leeds, concludes that over recent decades the Himalayan glaciers have lost ice ten times more quickly over the last … Read more

How the Female Brain Responds to Genital Touch – And How It Varies Among Women

Female Brain Analysis Neuroscience Concept

By Society for Neuroscience December 20, 2021 The thickness of the cortical region varies among women, associated with its use. The exact location of the brain area representing genital touch varies among women. The new research in JNeurosci also found the region was thicker the more frequently the participants engaged in sexual intercourse. The somatosensory … Read more

Measuring a Quantum Computer’s Power Just Got Faster and More Accurate

Futuristic Computer Concept

Scientists at Sandia National Labs invent new yardstick for benchmarking performance. What does a quantum computer have in common with a top draft pick in sports? Both have attracted lots of attention from talent scouts. Quantum computers, experimental machines that can perform some tasks faster than supercomputers, are constantly evaluated, much like young athletes, for … Read more
