A lethal pulse of ultraviolet (UV) radiation may have played a role in Earth’s biggest mass extinction event, fossilized pollen grains reveal. Pollen that dates to the time of the Permian-Triassic mass extinction event, roughly 250 million years ago, produced “sunscreen” compounds that shielded against harmful UV-B radiation, the analysis found. At that time, approximately … Read more

Ancient microbial life on Mars could have destroyed the planet’s atmosphere through climate change, which ultimately led to its extinction, new research has suggested. The new theory comes from a climate modeling study that simulated hydrogen-consuming, methane-producing microbes living on Mars roughly 3.7 billion years ago. At the time, atmospheric conditions were similar to those … Read more
