A dramatic view of Tropical Storm Barry unlike any you may have seen before

Posted on Categories Discover Magazine

An animation of GOES-16 satellite imagery acquired in the infrared reveals the evolution of Tropical Storm Barry on Friday, July 12, 2019. The crackling white and blue areas are indicative of lightning activity. (Source: RAMMB/CIRA GOES-16/17 Loop of the Day) Tropical Storm Barry is now expected to make landfall as a hurricane. As I'm writing this Thursday afternoon, July 12, Barry is churning slowly over the northern Gulf of Mexico, strengthening as it tarries over warm water. As it nea ...read more

Scientists Made a Microbe-Boosting Diet to Help Malnourished Kids Grow

In developing countries, the number can be as high as one in three. The problem? Malnutrition. Now scientists have developed a diet that can boost key colonies of gut bacteria in malnourished kids. The finding is important because past research has shown these bacteria are essential for healthy growth and development. The study paves the way for a new ...read more

What Are Intermediate-Mass Black Holes?

Posted on Categories Discover Magazine

The hunt for intermediate-mass black holes (IMBH) has picked up over recent years, and there are now dozens of promising candidates. This artist's concept depicts a 2,200 solar mass IMBH suspected to reside in the heart of the globular cluster 47 Tucanae, located some 15,000 light-years from Earth. (Credit: B. Kiziltan/T. Karacan) Black holes have long served as fodder for science fiction — and for good reason. These unimaginably dense objects contain so much matter trapped in such a sm ...read more

NASA Built Rock Climbing Robots to Scale Cliffs on Mars and Beyond

LEMUR can climb walls with special gripping feet, and is only one of a suite of climbing NASA robots. (Credit: NASA/JPL-Caltech) NASA has built many adventurous robots that can fly in space, land on alien planets, roll across Martian and lunar terrain, and even fly helicopter-style across far-off worlds. But the next big challenge is climbing and clambering across rough or steep terrain, a common sight whether on rocky Mars or icy Enceladus. To that end, NASA’s Jet Propulsion Labora ...read more

Are These Supermassive Black Holes on a Collision Course?

Posted on Categories Discover Magazine

This galaxy, which sits about 2.5 billion light-years away, hosts two supermassive black holes (inset), visible because of the heated gas, dust, and stars around them. The two black holes are on a collision course, but astronomers still aren't sure whether they will - or can - merge. (Credit: A.D. Goulding et al./Astrophysical Journal Letters 2019) By now, merging black holes and the gravitational waves they produce are a scientific surety. Astronomers have observed several black hole merger ...read more
