Scientists may have found a powerful new way to hunt for alien life — not by searching for specific molecules, but by looking for hidden patterns in how those molecules are organized. Researchers discovered that living systems leave behind a kind of chemical “fingerprint” in
Hubble has revealed a giant planet-forming disk unlike anything astronomers have seen before. Nicknamed “Dracula’s Chivito,” the enormous structure appears turbulent and oddly lopsided, with towering filaments visible on only one side. The disk contains enough material to
Astronomers using NASA’s James Webb Space Telescope have created the clearest map yet of the universe’s “cosmic web” — the enormous hidden structure that connects galaxies across space. By analyzing more than 164,000 galaxies through the massive COSMOS-Web survey, researchers
Isotope analysis of gas from geothermal springs in Zambia could show that a new continental rift is forming, scientists say. Unexpectedly high helium isotope ratios indicate that a weakness in Earth's crust has broken through to reach the mantle beneath. This rift could
The search for Earth 2.0 has begun in earnest. But there's a huge variety of exoplanets out there, so narrowing down the search to focus valuable telescope time on only the best candidates is critical. One variable of a planet that will have a huge impact on its habitability is
Birds of prey and vultures (raptors) play a vital role in ecosystems, both as top predators and key scavengers. However, compared to many other bird species, raptor populations are declining faster. This is because they need large areas to live in, have low population
Identifying and analyzing climate risks is a necessary function of governments, but researchers at Adelaide University's Environment Institute argue such processes will not lead to effective action without taking additional steps to understand which risks are considered
In early phases of drug development, new active substances are tested in animals—alongside numerous other experimental methods. Researchers face a dilemma: on the one hand, for ethical reasons, they aim to keep the number of animals used in an experiment as low as possible. On
A recent study published in the International Journal of Osteoarchaeology documented skeletal changes linked to scurvy in Late Holocene archaeological sites in California (500 BCE–1834 CE). The change observed shows the cascading impacts of dietary practices on skeletal
Staying strong may be one of the biggest secrets to living longer — especially for older women. A major study of more than 5,000 women found that simple signs of muscle strength, like a firm hand grip or the ability to quickly stand up from a chair, were strongly linked to
