Using the Chandra X-ray spacecraft, astronomers have seen a jet from a feeding supermassive black hole churning gas surrounding a galaxy nicknamed the "red potato."
Unsweetened sparkling water may offer a tooth-friendlier alternative to sugary soda, according to a small preliminary study tracking how different drinks change mouth acidity. Soda caused the strongest and longest drop in salivary pH, while sparkling water produced only a tempora
Animals are constantly moving to find food, water, suitable habitats, mates and safe places to rest. Because moving requires substantial energy, animals often rely on various biological and behavioral strategies to reduce unnecessary costs while seeking available resources.
Early humans in England crafted a rare piece of elephant bone into a reusable hammer for sharpening stone tools nearly 500,000 years ago. The extraordinary find reveals that ancient toolmakers were resourceful, skilled, and capable of surprisingly advanced planning.
Black holes represent some of the most extreme environments in the universe. They are the sources of the strongest gravitational fields, allowing us to test Einstein's theory of general relativity to an extent impossible with small objects. But we are also reaching the limit of w
There are countless cultures and societies around the world, spanning thousands of years. One thing they all have in common is that death is a part of everybody's life. Examining how different societies commemorate their dead can give archaeologists and anthropologists insight in
Searching for extraterrestrial intelligence has so far primarily meant focusing on one particular type of signal—and that signal has normally been based on our own current cutting-edge technology. But what if that's the wrong way to look for signs of alien intelligence? What if a
A new study published in Nature Physics reports the first direct experimental evidence of a Floquet topological state, a novel light-induced phase of matter that, until now, has existed only on paper and in simulations. Topological insulators can conduct electricity along their s
Scientists have pinned down why a sprinkler spins when it sucks in water instead of spraying it out — a problem that stumped Richard Feynman and has divided physicists for nearly a century.
The U.S. Federal Communications Commission (FCC) can single-handedly approve space projects that will change the night sky around the world. The international community can do very little against it.
One of the challenges of searching for technosignatures (i.e., signs that intelligent life somewhere in the universe has created technology) is understanding what to look for. Technology is a very broad area, and different types would show up as different features. One of the mos
Les États-Unis connaissent leur pire épidémie de rougeole depuis 35 ans, avec plus de 2.300 cas recensés depuis le début de l'année. La maladie, considérée comme éradiquée depuis 2000, fait son retour sur fond de recul de la vaccination et de défiance croissante envers les vaccin
