The hailstone is so massive it even stunned meteorologists. “It’s incredible,” said meteorologist Matthew Kumjian from Penn State University in the US. “This is the extreme upper end of what you’d expect from hail.” The hefty ice lump smashed down from a supercell thunderstorm in Argentina two years ago, in the heavily populated town Villa Carlos

A single tail from one of the largest and most enigmatic dinosaur species looks to have solved a longstanding mystery about these extinct creatures: whether they could swim. The discovery of a giant fossilised tail belonging to the theropod Spinosaurus aegyptiacus suggests these huge predators were aquatic animals after all, using tail-propelled locomotion to swim

It’s been a busy week for astrophysicist Michel Mayor. On Tuesday, he won a Nobel Prize for his work detecting exoplanets. Then, on Wednesday, he crushed the dreams of anyone hoping to one day colonize those planets. “If we are talking about exoplanets,” Mayor told Agence France-Presse when asked about off-world colonization, “things should be clear: we will not migrate there.”

Unlike some creatures, humans can’t regenerate their limbs – but a new study suggests we do have a hidden ‘salamander-like’ ability to regrow cartilage in the body, a finding which could help treatment for joint injuries and even arthritis. Using mass spectrometry techniques on 18 specimens, researchers were able to identify a mechanism by which

At its heart, climate change denial is a conflict between facts and values. People deny the climate crisis because, to them, it just feels wrong. As I’ve argued elsewhere, acknowledging climate change involves accepting certain facts. But being concerned about climate change involves connecting these facts to values. It involves building bridges between the science

Scientists have observed a quantum vibration at normal room temperature for the first time, a phenomenon that usually requires ultra-cold, carefully calibrated conditions – bringing us another step closer to understanding the behaviour of quantum mechanics in common materials. The team was able to spot a phonon, a quantum particle of vibration generated from high-frequency

Our diets can have a big environmental impact. The greenhouse gas emissions involved in producing and transporting various foods has been well researched, but have you ever thought about the water-scarcity impacts of producing your favourite foods? The answers may surprise you. In research recently published in the journal Nutrients, we looked at the water
