About 66 million years ago, the Chicxulub asteroid smashed into Earth, kicking up tsunamis and dropping hot debris that annihilated non-avian dinosaurs and many other species. But not everything it left in its wake was destructive. This space rock hit what is now the partially submerged Yucatan Peninsula, and at the bottom of the ocean, ..

Most implants like pacemakers and insulin pumps work in isolation. To help them coordinate with each other, a team of Georgia Tech researchers built a networking system that sends signals through body tissue instead of antennas and radio waves. Radio problems Implants that communicate today mostly rely on radio protocols like Bluetooth Low Energy or ..
The first in a new class of space telescopes is on track to reach the launch pad in the early 2030s, NASA announced this week. The PRIMA mission will be the first of NASA’s Probe Explorers, a new line of observatories intended to do more science for less money. The agency’s space telescopes typically fall ..
For a long time, sleep research has treated the cerebral cortex as a passive follower reacting to signals from the deep brain. “Usually, sleep is associated with being controlled by subcortical regions,” said Geoffrey Terral, a neuroscientist at the Albert Einstein College of Medicine in New York. The cortex is where the slow rhythms of ..

The International Meteor Organization, the nonprofit that coordinates and publishes amateur and professional observations of meteor phenomena, said its infrastructure has suffered a “critical blow” from a cyberattack. “We recently suffered a cyberattack that dealt a critical blow to aging infrastructure, taking much of our site offline,” a static page on its website on Wednesday ..
In recent years, there has been a lot of excitement about the potential for studying human diseases in what are called “organoids.” These small patches of tissue, formed using stem cells, appear to produce many of the same cell types and at least some of the structures normally formed in actual organs, and thus can ..
The Vesuvius Challenge is an ongoing project that combines “digital unwrapping” with crowdsourced machine learning to decipher the so-called Herculaneum scrolls, badly charred 2,000-year-old papyri too fragile to be physically unrolled. The effort just got an additional boost. A team of researchers created their own contemporary model papyrus scrolls—charring them just like the originals—to validate ..
Our basic understanding of core-collapse supernovae hasn’t changed in decades. Large stars burn through all the fuel at their cores and start creating heavier elements in reactions that consume energy. The lack of energy from these reactions allows gravity to pull the interior of the star in on itself, collapsing it into a neutron star ..
On the heels of the hottest summer on record and a United Nations report warning that global temperatures are likely to push climate risks to “increasingly dangerous heights,” the Trump administration overturned most of a Biden-era rule limiting climate pollution from power plants, the second-largest source of greenhouse gas emissions. The Environmental Protection Agency announced ..
