A dinosaur, possibly a young Tyrannosaurus rex, excreted a bird 66 million years ago, and one of its feathers is exquisitely preserved in the fossilised dropping
Wrinkles on the surface of Mercury have revealed that the closest planet to the sun is shrinking faster than scientists thought.

Scientists have directly observed how two negatively charged DNA molecules can pair up despite normally repelling each other. Positively charged metal ions appear to bridge the gap, helping matching D...
A newly identified link between amino acid metabolism and cholesterol production may help prostate tumors adapt to hormone therapy. Prostate cancer can find ways around treatments designed to deprive ...
About 66 million years ago, a dinosaur—maybe a T. rex or a Nanotyrannus—ate a bird. The record of that meal, in the form of fossilized poop, has survived to today, preserving the best example of a fea...
Since OpenAI announced its solution to one of the prestigious Millennium Prize Problems, mathematicians have been urgently trying to unpick what it means
Mars is a terrible place to build a house. It's bitterly cold, blasted by radiation and a near vacuum. Not to mention that the building materials, even for a modest shelter, could spend months hurtlin...
The joint BepiColombo mission of the European Space Agency (ESA) and the Japan Aerospace Exploration Agency (JAXA) is settling into orbit around Mercury after an eight-year journey. In early September...
In drought-prone regions of Ethiopia, growing more food could start with something as simple as keeping more rainwater in the ground.
Nitrogen is a key ingredient in the biomolecules that form the building blocks of life. Yet as an unbonded gas, it is far more likely to drift into space than to lock itself into solid compounds, maki...
Europe's climate monitor said Thursday that August was the hottest month ever recorded worldwide and warned of worse to come as an unprecedented El Niño pattern grows stronger.
In 2025, associate professor Christian Busch's Palisades home burned down in one of the most destructive wildfires in Los Angeles history. Busch says the disaster wasn't blind bad luck; it was a clear...
An ancient cave in southwestern China has revealed new evidence about how Denisovans—an ancient human relative—lived, survived and adapted over more than 100,000 years.
Superconductors are materials that carry electricity with zero resistance below specific temperatures. Many of these materials become superconducting at very low temperatures, yet some enter supercond...
As cost-of-living pressures increase and the rental crisis worsens, many families are moving more often.
Lots of animals use mimicry to survive. Some copy the appearance of threatening predators, and others have evolved to resemble plants or rocks so they can blend into the background and avoid being att...
