Astronomers have detected one of the most powerful ultra-fast outflows ever seen from a distant supermassive black hole. Using XMM-Newton and NuSTAR, a team studied a hyper-luminous quasar at cosmic noon and found two distinct ...

Genes aren't just transferred from parents to their offspring. Nature has found other ways to pass on genetic information, even between different species. And a new study, published in the journal Proceedings of the National ...

Could the secret to preventing dangerous falls be surprisingly simple? For older adults, these unexpected tumbles are a leading cause of injury, affecting roughly 1 in 4 people 65 and older each year. What if the key isn't ...

Many quantum effects can be observed only when a small number of particles is studied—individual atoms, molecules or photons, for example, carefully shielded from the rest of the world. But what about macroscopic objects, ...

Digital matching platforms—from professional networking to ride-sharing and accommodation services—add value by bringing supply and demand into balance. But deep-seated asymmetries can prove difficult to expunge, causing ...

People who are hesitant to try insect-based foods may enjoy the experience more than they expect—and can become more open to expanding their diets in the future, according to research published by the American Psychological ...

Most people have experienced a heat wave on land. But heat waves can strike in the ocean too. And as the planet continues to warm, marine heat waves are growing longer and deadlier, hurting the seafood supply that billions ...

AI is growing fast, and keeping up means building more data centers, manufacturing advanced chips and powering the tech behind it. All of that comes with a carbon cost. AI advocates claim that in the long run, AI will save ...

Between the mid-1970s and early 1980s, two physicists, Michael Hart and Frank Tipler, published a controversial series of papers arguing that extraterrestrial intelligence didn't exist. As they argued, the likelihood that ...

An international study of infant remains from 50,000–75,000 years ago has provided new evidence about the developmental trajectory of our evolutionary "cousins," Neanderthals.

Physicists have long been drawn to the nonlinear Hall effect: a subtle variant of the classical Hall effect, in which an electric voltage appears perpendicular to a current flowing through a material. Unlike its classical ...

Goats appear to have a rare ability not shared by many in the animal kingdom, and that is being able to follow the direction of a human voice to locate hidden objects. While dogs have been shown to do this, even our closest ...
