Roman leader Julius Caesar is said to have kept a stock of it in the treasury. Ancient writer Pliny the Elder says Rome's Emperor Nero owned the last stalk of it. And some have suggested rampant extra...
Seeing Earth from space changes your perspective. And this "overview effect" is magnified when you're looking back from beyond the moon, according to Artemis 2's Christina Koch.
A new University at Buffalo study finds that people in the United States generate similar amounts of plastic packaging waste regardless of income, education level or where they live. Yet wealthier and...
The Artemis II astronauts—three Americans and one Canadian—hurtled deeper into space than any other humans during a moon flyby Monday that marks NASA's lunar comeback.
Still aglow from their triumphant lunar flyby, the Artemis II astronauts made more history Tuesday: calling their friends aboard the International Space Station hundreds of thousands of miles away as ...
Research in New Phytologist shows that plants can acquire nutrients not only from the soil but also from atmospheric dust that settles and dissolves on their leaves, releasing elements such as phospho...
A bizarre, record-breaking neutrino detected in 2023 may have originated from an exploding primordial black hole—a relic from the early universe. Scientists suggest these black holes could carry a mys...
Planetary exploration may be about to get a major speed boost. Researchers tested a semi-autonomous robot that can move from rock to rock, analyzing each without waiting for human instructions. The sy...
Last year Kenya Wildlife Service warned of a growing demand for garden ants in Europe and Asia, where some people view them as exotic pets. An attempt to smuggle over 2,000 garden ants out of the coun...
Quantum computers struggle with a major flaw: their information vanishes unpredictably. Scientists have now created a new method that can measure this loss over 100 times faster than before. By tracki...
A new paper in Molecular Biology and Evolution, finds that changes in animal development induced by climate shock persist generations after the initial event. The escalating effects of climate change ...
A massive, old caldera and more recently formed craters shape the landscape in the eastern Sierra Nevada.
Leo is a prominent sight for stargazers in April. Its famous sickle, punctuated by the bright star Regulus, draws many a beginning stargazer’s eyes, inviting deeper looks into some of Leo’s celestial ...
A team of university and Tribal researchers has developed a blueprint for creating research agreements that enable respectful research with Tribes and on Tribal lands. The guidance was developed to ad...
Florida is among the wettest U.S. states, but that doesn't mean it is drought-free. Nearly all of Florida faced at least "moderate" drought, and nearly 80% faced "extreme" conditions in April 2026, ac...
Scientists have zoomed in on how phosphoric acid moves electrical charges so efficiently in both biology and technology. By freezing a key molecular pair to extremely low temperatures, they found it f...
A famous “oldest octopus” fossil has been exposed as a case of mistaken identity. Advanced imaging revealed hidden teeth showing it was actually related to a nautilus, not an octopus. The confusion ca...
Differences of opinion on climate change among the Dutch have not increased over the past 40 years; in fact, they have decreased, according to a study conducted by sociologists Anuschka Peelen and Joc...
Researchers have developed a cutting-edge technique that uses RNA “barcodes” to map how neurons connect, capturing thousands of links with single-synapse precision. The method transforms brain mapping...
