The student headlines that matter, in one email every morning. Free.
For decades, discussions and decisions about access to contraception, abortion, maternal health care, HIV prevention and treatment, comprehensive sexuality education, gender equity and protection from sexual violence have largely flowed in one direction: from the Global North to
The interstellar comet 3I/ATLAS carries a chemical clue to conditions in the planetary system of its origin, locked away long before it reached our sun. Its methane signature is unusually rich in heavy hydrogen, suggesting that the comet's frozen ingredients took shape in an inte
Scientists at the University of Virginia have developed a promising new strategy to fight glioblastoma, one of the deadliest and most difficult-to-treat forms of brain cancer. Their experimental approach combines focused ultrasound, tiny nanoparticles, and genetic molecules calle
Many have voiced concerns that artificial intelligence will take jobs away from humans. But assistant professor of chemistry Zhongyue (John) Yang, along with his former doctoral student Qianzhen Shao (now a postdoc at Stanford) and other team members, has created an AI tool that
Spatial mapping reveals how human urogenital organs codevelop during organogenesis and more — today's student signal.
A new study has mapped human urogenital development in its native spatial context, revealing how neighboring organs coordinate their development through cellular communication and molecular signaling during embryogenesis.
Scientists have recreated a primordial state of matter from the dawn of the universe by colliding oxygen nuclei at nearly the speed of light. The surprising results show that this exotic substance can form in smaller, lower-energy collisions than previously demonstrated, challeng
College students say they use AI mostly for learning and don't use it to cut corners but think that their peers do, according to the inaugural Dartmouth AI Survey, a new multiyear survey on how AI is shaping students' learning and career readiness.
Every day, two NASA space instruments known as the Orbiting Carbon Observatory-2 and -3 (OCO-2 and OCO-3) capture more than a million observations of sunlight reflecting off Earth's surface. Using the physics of how light travels through the air, an algorithm converts these raw d
Offer your employees money to quit and the ones who say no will work harder as a result. Researchers at the University of Waterloo, Wilfrid Laurier University and McMaster University set out to test whether pay-to-quit programs work as intended. Their results confirmed they do an
Grades from compulsory school determine which pupils are accepted into popular upper secondary programs. A new thesis from Uppsala University shows that pupils at for-profit independent schools have, on average, higher grades than would statistically be expected given their backg
African cuckoo finches (Anomalospiza imberbis) are very deceptive birds, or at least the mothers are. They sneak into the nests of other birds, such as prinias and cisticolas, to lay their eggs, then slip away and leave the hosts to raise the chicks.

When we hear that climate change is damaging natural environments, it conjures images of rising seas eroding coastlines, or heat waves bleaching the Great Barrier Reef. But what about deserts?
A University of Bath–led study has estimated that the carbon dioxide produced by humans as our bodies turn food into energy rose by 74% between 1985 and 2015, reaching 2.05 billion metric tons a year. Researchers say the findings could help scientists better understand where carb
Tucked away among its sensors, cameras and navigation tools, NASA's Mars rover Perseverance is wearing small swatches of spacesuit material. A rover doesn't need a spacesuit, but the swatches—each less than a square inch (6.5 square centimeters) in size—serve an important purpose
Authorities in New Delhi stepped up anti-pollution measures on Sunday, including higher parking fees and work-from-home orders, seeking to curb toxic smog in one of the world's most polluted capitals.
Long dubbed an "air-conditioned nation," Singapore is experimenting with cooling alternatives from chilled beams to "passive displacement" to curb its thirst for energy-guzzling air conditioning.
Guided by the beam of a flashlight, Tino Marolo follows his dog Stella through the darkness of a Piedmont woodland, searching for one of Italy's most prized culinary treasures hidden beneath the soil.
Nowhere in the Iberian Peninsula or the Balearic Islands has a tropical climate—for this to be the case, the average temperature in the coldest month would have to be 18°C (64 degrees Fahrenheit) or higher. The contrast between Spain's winters and summers, and the low temperature
In a study spanning 192 sites and four continents, researchers have discovered that conifers planted in the Southern Hemisphere grow up to four times faster and are more drought-resistant than those growing in their native ranges.
Sleep is fundamental to well-being. Decisions to end semiannual clock changes and remain on permanent daylight saving time (DST) in British Columbia, the Northwest Territories, Alberta, Manitoba and northwestern Ontario have consequences for many Canadians due to potential sleep
