For nearly fifty years, mathematicians have puzzled over a deceptively simple question: how small can you make a Möbius strip without it intersecting itself? Now, Richard Schwartz, a mathematician at Brown University, has proposed an elegant solution to this problem, which was originally posed by mathematicians Charles Weaver and Benjamin Halpern in 1977. In their

When strong hurricanes hit land, the uprooted trees, destroyed homes, and other devastation are highly visible. What happens in the marine environments where they churn water and disrupt sediment isn’t always as obvious. A vast array of marine life lives along the Florida peninsula, the US state where hurricanes make landfall most often. The Florida

Climate change has sharply boosted the risk of fast-spreading wildfires, according to a Californian study published Wednesday that offers lessons for prevention after recent disasters in Canada, Greece and Hawaii. Scientists at the Breakthrough Institute, a non-profit research centre, found that human-caused warming increased the frequency of “extreme” wildfires by 25 percent on average compared

Sea ice loss in Antarctica during 2022’s emperor penguin breeding season resulted in the complete failure of four out of the five breeding colonies in the Bellingshausen Sea. Satellite imagery shows none of the chicks from those sites survived. The devastating event is the first recorded widespread breeding failure of emperor penguins (Aptenodytes forsteri); but,

A research team in France found the Nile crocodile reacts to the distress cries of many different baby mammals, including humans. Their response is sensitive to specific acoustic details, which may help the predators gauge the severity of their prey’s distress before attacking. By playing recordings of crying bonobos (Pan paniscus), chimpanzees (Pan troglodytes), and

“A diamond is forever.” That iconic slogan, coined for a highly successful advertising campaign in the 1940s, sold the gemstones as a symbol of eternal commitment and unity. But our new research, carried out by researchers in a variety of countries and published in Nature, suggests that diamonds may be a sign of break up
