Since the discovery of graphene in 2004, there’s been a proliferation of strange new two-dimensional materials. In all of them, scientists have been chasing one invaluable property – magnetism, which is crucial for data storage, medical devices, and electricity generators. After years of searching, many suspected that true two-dimensional magnets might not actually exist. But

Scientists have uncovered the earliest hints of human-caused changes in Earth’s geological processes, and they suggest that we’ve been impacting the planet’s climate and ecosystems for up to 11,500 years. Based on core samples dug up from the Dead Sea, erosion rates in the area were completely incompatible with what was going on elsewhere during

Some 5,000 light-years from Earth, there’s a bizarre and mysterious nebula that clocks an average temperature of just 1 Kelvin (−272.15 °C or −457.87 °F), making it the coldest natural object in the known Universe. For decades, scientists have struggled to explain how this otherwise unremarkable cloud of gas maintains temperatures colder than empty space

For every ten people hit by lightning, nine will survive. But what are the lasting effects of being exposed to hundreds of millions of volts? Sometimes they’ll keep the clothing, the strips of shirt or trousers that weren’t cut away and discarded by the doctors and nurses. They’ll tell and retell their story at family
