At the end of its life, the enigmatic star will shine like a beacon in the sky First it was the strange dimming of Betelgeuse. Now it’s a gravitational wave that once again has astronomers scratching their heads over this enigmatic star found in the constellation Orion. Betelgeuse has been grabbing a few headlines lately, as the normally…

A new semiconductor made from lithium, indium, phosphorus, and selenium could lead the way to hand-held, portable, sensitive neutron detectors (Nature 2020, DOI: 10.1038/s41586-019-1886-8). Such instruments can spot nuclear materials and play key roles in national security, nuclear medicine, and scientific research. Neutron detectors rely on the neutron-absorbing properties of a small number of nuclides…

Albert Einstein famously said that quantum mechanics should allow two objects to affect each other’s behaviour instantly across vast distances, something he dubbed “spooky action at a distance”1. Decades after his death, experiments confirmed this, but to this day, it remains unclear exactly how much coordination nature allows between distant objects. Now, five researchers say…

Shortly after the Solar System formed, astronomers think it went through what’s known as the Great Divide – a splitting up of the planets into two distinct groups. We weren’t around to experience this cosmic schism, but a new study has put forward an intriguing hypothesis on how it would have occurred. Put simply, the Great…
