Climate Change May Be Speeding Up Ocean Circulation

Winds are picking up worldwide, and that is making the surface waters of the oceans swirl a bit faster, researchers report. A new analysis of the ocean’s kinetic energy, measured by thousands of floats around the world, suggests that surface ocean circulation has been accelerating since the early 1990s. Some...

Drones Help Scientists Weigh Whales At Sea

Weighing a whale is a beast of a challenge. Scientists who study these majestic mammals can’t just hoist them out of the water and plop them onto some scale. But researchers now have a method to estimate a whale’s weight without disturbing it. The approach uses drone imagery of the animals at...

Generating Electricity from the Cold Night Sky

Generating Electricity from the Cold Night Sky

A new device works like a solar panel, except it doesn’t harvest energy from the sun. It captures energy from the cold night sky. A prototype of the device produced enough electricity at night to power a small light bulb. A bigger version might one day light rooms or charge phones. It...

Latest Claim of Turning Hydrogen into A Metal May Be the Most Solid Yet

Latest Claim of Turning Hydrogen into A Metal May Be the Most Solid Yet

Physicists are crushing it — hydrogen, that is. Squeezing the chemical element to extremely high pressure transforms it into a metal, a trio of researchers claims. The purported metallic hydrogen appeared at a pressure more than 4 million times that of Earth’s atmosphere, the scientists report June 13 at arXiv.org. If confirmed,...

Mosquitoes can hear up to 10 meters away

Mosquitoes can hear up to 10 meters away

Mosquitoes can hear over distances much greater than anyone suspected, according to researchers at Cornell and Binghamton University. Their findings were published in the journal Current Biology. Until now, scientists believed that organisms required eardrums for long-range hearing, and that the feathery antennae with fine hairs that mosquitoes and some insects...

Your Gut Is Directly Connected to Your Brain

Your Gut Is Directly Connected to Your Brain

The human gut is lined with more than 100 million nerve cells—it’s practically a brain unto itself. And indeed, the gut actually talks to the brain, releasing hormones into the bloodstream that, over the course of about 10 minutes, tell us how hungry it is, or that we shouldn’t have...

Big Data Reveals Hints of How, When and Where Mental Disorders Start

Big Data Reveals Hints of How, When and Where Mental Disorders Start

Psychiatric disorders’ many complexities have stymied scientists looking for clear genetic culprits. But a new giant dataset holds clues to how, when and where these brain disorders begin. Called PsychENCODE, the project’s first large data release has revealed intricate insights into the behavior of genes and the stretches of genetic...

Artificial intelligence could improve predictions for where quake aftershocks will hit

A new artificial intelligence is turning its big brain to mapping earthquake aftershocks. Scientists trained an artificial neural network to study the spatial relationships between more than 130,000 main earthquakes and their aftershocks. In tests, the AI was much better at predicting the locations of aftershocks than traditional methods that many seismologists...

Smart Windows Could Block Brightness And Harness Light

Who needs curtains? One day, you could block out afternoon glare and heat with changeable windows that absorb sunshine to charge your electronics. A high-tech prototype panel described online January 22 in Nature Materials, switches between transparent pane and dark-tinted solar cell. The layer in the panel that’s responsible for soaking up...
