A hundred years ago, Einstein predicted the existence of gravity waves. Today, for the first time, scientists announced that they’ve actually been detected. Here’s what the discovery might mean for our understanding of the universe.
About a decade ago, several of Greenland’s biggest glaciers suddenly began melting. A decade later, two groups of scientists are trying to unlock the secrets behind a scientific mystery story with potentially big consequences for the future of the island’s rapidly-melting ice sheet.
Minorities are historically underrepresented in science, technology, engineering and math fields. John Dimandja is a Congolese chemist on the faculty of Spelman College who’s pointing the way into STEM careers for students of color.
Iceland is — geologically speaking — a crazy place. The local language, for instance, includes a specific word to describe the phenomenon for a volcano detonating beneath a glacier and triggering a flash flood. And now our changing planet may be setting a new geological domino effect in motion.
Scientists at MIT have embedded slices of brain in the absorbent material found in diapers, which swells 4-5 times its normal size. And when they look at the expanded result using an ordinary light microscope, they see an unprecedented view of nerve fibers, cells, and proteins. It’s the deepest look into the brain we’ve ever had.
Trees are nature’s tool for pulling carbon dioxide out of the air, but there aren’t enough trees in the world to suck up all the CO2 humans are putting there. That’s why researchers are pushing to create artificial leaves to help fight climate change. I visit with two teams of researchers pursuing different approaches to the formidable challenge.
