The Juno spacecraft’s first closeup views of Jupiter’s Great Red Spot are here. The spacecraft flew just 9,000 kilometers above the famous storm on July 10. Scientists had expected the images to take until at least the night of July 13 to download because the spacecraft’s antenna was pointed away from Earth. But the first […]

Ravens have passed what may be their toughest tests yet of powers that, at least on a good day, let people and other apes plan ahead. Lab-dwelling common ravens (Corvus corax) in Sweden at least matched the performance of nonhuman apes and young children in peculiar tests of advanced planning ability. The birds faced such […]

Walls can’t talk, but scientists can now read stories written in their subatomic particles. And that could make it harder to store radioactive material in secret. Nuclear radiation rearranges the electrons in insulators such as brick, glass and porcelain. So comparing the positions of electrons in atoms at different spots on walls, windows and floors […]

Rowa Mohammed Assayaghi teaches people how to wash their hands. In Yemen, that’s life-saving work. The Middle Eastern country is facing the world’s largest cholera outbreak, with nearly 409,000 suspected cases and 1,885 deaths from late April to late July, the World Health Organization reports. That tally is higher than 2015’s worldwide reported cholera deaths. […]

The star of any solar eclipse is, of course, the sun. And total eclipses give the sun’s wispy, tenuous atmosphere the spotlight. This region, called the corona, is normally too dim to observe directly. But with the moon blocking the sun’s bright disk, the corona comes into view. And the view is dazzling. The corona’s […]

Take a bow, Cassini. It’s been a marathon performance: 20 years in space, more than 200 orbits around Saturn, and hundreds of thousands of images of the giant planet, its splashy rings and its many moons. On September 15, the veteran spacecraft will use its last burst of fuel to plunge into the sixth planet […]

Islamic militants and their fiercest opponents fight and die for intensely spiritual reasons, a new report finds. Islamic State (also known as ISIS) soldiers and Kurds who have fiercely battled them sacrifice themselves for sacred, nonnegotiable values, says a team led by anthropologist Scott Atran of the University of Michigan in Ann Arbor. These soldiers’ […]

Very subtle control of artificial limbs by means of a tiny electronic device may become possible.… [The] electronic device … [is] designed to be injected into a muscle through a thick hypodermic needle. A tiny package strapped to the outside of the limb will beam radio waves at the device, which will return them, modified […]

“The strangest place in the whole universe might just be right here.” So says actor Will Smith, narrating the opening moments of a new documentary series about the wonderful unlikeliness of our own planet, Earth. One Strange Rock, premiering March 26 on the National Geographic Channel, is itself a peculiar and unlikely creation. Executive produced […]
