Prospecting for pluripotency Prospecting for pluripotency, Published online: 22 June 2018; doi:10.1038/s41576-018-0030-1 Unlike most organisms, planaria maintain pluripotent stem cells (PSCs) beyond embryogenesis. A new study reports the prospective identification and isolation of a neoblast subpopulation containing adult PSCs, characterization of which should help uncover the mechanisms underlying pluripotency and tissue regeneration.

The curvature of empty space caused by an entire galaxy has now been pinned down with unprecedented precision, demonstrating Einstein’s theory of general relativity still rules on a super-sized scale. Not that anybody is seriously surprised. But on the off chance the results had failed to meet expectations, they might have provided insight into some

A city-size asteroid or comet is thought to be responsible for that mass extinction. The impact, called the Chicxulub event, triggered global cooling and volcanic eruptions that transformed Earth. In the 1980s, Richard Muller,

The central section of the San Andreas Fault in California is moving in an unexpected way, scientists say, creating a series of ‘slow earthquakes’ that increase the likelihood of a major quake striking in the future. It was previously thought that slow and steady movements in this area were safely releasing pent-up energy along the faultline,
