Strange, sinuous gullies etched into the dunes of Mars are finally giving up their secrets. These gouges, new experiments reveal, are carved by the explosive sublimation of dry ice, burrowing down the slopes like a mole and blasting away sand as it goes. The new results finally account for all the curious features of Mars’ mysterious squiggles. “It felt like …

Two Russian cosmonauts are back inside the International Space Station after conducting a spacewalk to install a semiconductor materials experiment, as well as retrieve and jettison a no-longer-needed camera from the exterior of the orbiting complex. Expedition 73 commander Sergey Ryzhikov and flight engineer Alexey Zubritsky, both with Russia’s federal space corporation Roscosmos, marked the end of their first extravehicular …

A strange new phase of ice has been discovered during experiments with the world’s largest X-ray laser. Meet ice XXI, a bizarre phase that forms at room temperature, under extreme pressure. The solidified water we’re most familiar with here on Earth is technically known as ice I, but it’s just the tip of the iceberg – for instance, aliens on …

Scientists in Wales have built the world’s most sensitive table-top interferometer, which is a miniature, ultra-precise instrument capable of measuring distortions in space-time smaller than a trillionth of a human hair. The research team at Cardiff University took a bold step toward understanding the quantum nature of gravity by setting new limits on the existence of very high-frequency gravitational waves. …

You think a billion dollars is cool? To offer a Taylor Swift-specific paraphrase of The Social Network, you know what’s cool? Two billion dollars. Hot on the heels of her latest album release, The Life of a Showgirl, already a success on the charts, Bloomberg updated their estimate of Swift’s wealth and announced that, since they added her to their …

Fortunately, there are many ways you can prove to yourself that the Earth is indeed an oblate spheroid (or a sphere that bulges slightly at the equator). These range from the simple – looking at photos of the Earth from space, or simply at the stars – to using a few sticks and some shadows. But for some, that isn’t …

In a first-of-its-kind experiment, doctors in China transplanted a lung from a genetically modified pig into a brain-dead person. Similar experiments involving brain-dead patients have previously taken place in the U.S., but they involved different pig organs, such as kidneys and hearts, and a previous experiment in China involved a pig liver. These experiments have paved the way to transplants …

Study design We conducted a countrywide, prospective, longitudinal physical activity study of US residents that evaluated their physical activity levels within the context of the walkability of their built environments before and after relocation (‘participants’). We leveraged the naturally occurring physical activity data that was captured by a health app on participants’ phones to compare each person’s physical activity levels …
