Not every volcanic eruption is a Mount Vesuvius-like catastrophe, with rivers of fire and flying rock that rains down on unsuspecting Pompeiians. Sometimes, volcanoes’ summits collapse, forming miles-wide depressions called calderas, which are peppered by eruptive vents. When rivulets of magma force their way out of these vents, those small eruptions can spew dangerous amounts

Scientists have just discovered something new about gold. When extreme crushing pressure is applied quickly, over mere nanoseconds, the element’s atomic structure changes, becoming more similar to metals harder than gold. It’s the first time this structural state has ever been observed in gold, suggesting properties that could help scientists refine their understanding of how

Researchers have developed artificial cells that can respond to external chemical forces, just like real ones do. This exciting step could get us closer to using synthetic biological structures in real-world situations, such as targeted drug delivery or cleaning up pollution. In this proof-of-principle study, scientists have succeeded in getting artificial cells to glow with

Indian tiger numbers are up, according to one of the most detailed wildlife surveys ever conducted. Tiger populations have risen by 6 percent, to roughly 3,000 animals. The massive survey may set a new world standard in counting large carnivores. The encouraging results validate India’s impressive investments in tiger conservation. A mammoth effort Large, solitary

Over 200 Svalbard reindeer have been found dead on the Norwegian archipelago of Svalbard. That’s one of the highest recorded death tolls since population monitoring commenced in 1978, and scientists believe climate change played a key role. According to a report on the Norwegian Polar Institute’s website, the reindeer (Rangifer tarandus platyrhynchus) suffered a lean

If you think climate change is only gradually affecting our natural systems, think again. Our research, published in Frontiers in Marine Science, looked at the large-scale impacts of a series of extreme climate events on coastal marine habitats around Australia. We found more than 45 percent of the coastline was already affected by extreme weather
