Why some young ants start hunting and caring for others early
Some insects, including honeybees and ants, live in highly organized colonies where individuals take on specific roles. In many ant societies, young adult workers typically care for developing young inside the nest before beginning to forage, or search for food, outside it.
New catalyst enables lower-temperature methane conversion with sustained performance
Oxidative coupling of methane (OCM) is a chemical reaction that directly converts methane and oxygen, the main components of natural gas, into higher-value hydrocarbons such as ethane and ethylene. However, the reaction presents a fundamental selectivity challenge.
Why Old Dogs Might Be Able to Teach Alzheimer’s Researchers New Tricks
Most people know someone with Alzheimer’s disease . When I was growing up, my grandmother struggled with dementia, and I saw firsthand how difficult that was for our family. That experience was one reason I became a neurotoxicologist who studies how misshapen proteins and

Mountaineer: 'Tenzing biopic made me wonder what he would think if he could return to the mountain today'
Seventy-three years ago, Tenzing Norgay stood on top of Everest, known as Chomolungma in Tibetan, which roughly translates as "Goddess Mother of the World."
Geologists uncover evidence of a missing Late Cretaceous magmatic arc in northwestern Iran
Mountains preserve evidence of ancient oceans, moving continents and tectonic processes that have shaped Earth over millions of years. Later deformation, erosion and burial, however, can obscure important parts of this geological record. An international research team led by
Food testing reveals how diet can add to exposure to 'forever chemicals'
Per- and polyfluoroalkyl substances (PFAS)—a vast family of chemicals used largely for their nonstick, water-repellent and grease-resistant properties—are called "forever chemicals" because of their remarkable resistance to degradation. They are now ubiquitous in our environment.

Three quantum-inspired cores leave opposite fingerprints on the ringing of black holes
Every black hole hides a question at its center. Einstein's theory predicts that whatever falls in is crushed into a singularity, a point of infinite density where the theory itself breaks down. Most physicists expect quantum gravity to replace that point with something finite.
Major earthquake strikes Panama—damage and injuries are expected
The quake was a strike-slip event, and strong aftershocks could follow
Aspens 'remember' past drought in their leaves, 3-year experiment finds
Drought is written into trees, appearing as narrow bands in their annual growth rings. But aspen may go farther, creating "functional memories" of previous dry years reflected in the chemistry of their leaves, according to new research by University of Utah biologists.
NASA advances LISA mission contributions with new test telescope
NASA has taken the next step in the process of developing a new all-glass telescope for the LISA (Laser Interferometer Space Antenna) mission, a space observatory designed to detect ripples in space-time called gravitational waves.
