Science, engineering, and discovery — the research and breakthroughs that matter.

Ruthenium dioxide (RuO2) is a metal oxide that commonly serves as an important metallic conductor, quantum material and industrial electrocatalyst. While there have been debates surrounding the magnetic properties of RuO2, it is generally thought to be nonmagnetic in its bulk for

Ant parenting may have evolved from the same brain systems that once controlled hunger. Researchers found that two chemical signals push clonal raider ants toward either caring for larvae or leaving to forage, with the balance changing as the ants grow older. Similar signals are

Xenophagocytosis is a natural immune process that limits interspecies organ generation by eliminating living donor cells, researchers at the Institute of Science Tokyo, Japan, report. By uncovering how embryonic macrophages eliminate living donor cells, the researchers developed

Strengthening El Nino 'adding fuel to a planet already on fire': UN chief and more — today's student signal.

A strengthening El Niño that could shatter all-time records is "adding fuel to a planet already on fire" and pushing the world into "uncharted territory," U.N. Secretary-General Antonio Guterres warned Friday.

Finding water on the moon may only be a matter of detecting the right vibrations.

New wildfires fed by strong winds broke out in Greece on Friday, giving firefighters little respite and forcing Civil Protection officials to order the partial evacuation of part of a suburb west of Athens.

A new Concordia study has demonstrated a greener way to produce an important class of catalytic materials with promising potential for cleaner energy technologies that rely more on acoustic energy than water and chemicals. The work is published in the journal Advanced Synthesis &

They're wriggly black grubs more commonly tossed to backyard hens than served at the dinner table, but black soldier fly larvae could soon play a key role in building a more sustainable food system, according to new research from Adelaide University.

The modern workday unfolds largely indoors. Long hours spent commuting, sitting in meetings and staring at screens can make time outdoors feel like a luxury. Finding time for nature in an already packed workday can feel impossible, especially if you think nature only "counts" whe

Temporary anxiety can often surface before the first day of school. Sometimes, that can help kids get in the right mindset for a big day. But when anxiety becomes a constant feature of children's and teenagers' days, that stress doesn't switch off when they leave the classroom or

Along the Gulf Coast, black skimmers have long been a familiar sight—gliding just above the water with their bright orange beaks slicing through the surface to feed.

Researchers at Technical University of Darmstadt and the GSI Helmholtz Center for Heavy Ion Research have succeeded for the first time in decelerating highly charged ions from the GSI accelerator to low energies and subsequently storing them in a Penning trap. They were also succ

NYU researchers have made microscopic oil droplets in water do something usually reserved for living cells: change shape in complex, controllable ways and even engulf their surroundings.

Thick smoke from massive wildfires has been spreading in North America and Europe once again in 2026. The health impacts of breathing this particle-filled air are becoming well known, but wildfires' influence on the weather is less widely recognized.

For archaeologists, the Coëby cemetery in Brittany, France, is a gold mine for research. It contains several prehistoric stone monuments and earth mounds. In a new study of two unusually large mounds, scientists may have stumbled upon a rare style of funerary monument.

Strict regulations have prevented continental U.S. beekeepers from participating in the lucrative organic honey market, but new research finds that bees' actual habits make certain rules too extreme. The findings potentially provide evidence for federal agencies to ease restricti

The ancient Egyptian god of the moon had two very different faces: a crescent-beaked white bird and a silver-coated baboon. Now, researchers think they may have found the common thread connecting them all.

A brewing "super" El Nino cycle is poised to unleash heat waves, floods and drought worldwide, with the effects amplified by long-term human-caused climate change.

NASA’s Curiosity rover has entered a Martian valley covered by an astonishing “sea” of tiny polygon-shaped fractures. The honeycomb patterns, each only a few inches wide, stretch across the landscape and even wrap around a nearby 20-foot-tall butte.

Primordial black holes may occasionally pass through white dwarf stars and trigger enormous Type Ia supernova explosions. Researchers found that these events could explain chemical patterns seen in supernova remnants, nearby explosions, and stars across the Milky Way.

Researchers at Baylor College of Medicine and the Texas Department of State Health Services have reported a likely case of soft tick-borne relapsing fever (STRF) in an Austin-area resident. Now, they highlight the growing risk of exposure to infected ticks in urban and residentia
