In computer simulations of the Big One—a large-magnitude earthquake that may occur along the San Andreas Fault in California—seismic waves ripple from the epicenter of a magnitude 7.8 earthquake near the Salton Sea into the ...

Before buying a product, booking a hotel or streaming a movie, many people check online reviews. But not every glowing recommendation or one-star takedown reflects a genuine customer experience.

When scientists study bacteria that are not in a Petri dish or a test tube but in environments that more closely mimic their actual microbial habitats, they often find delightfully unexpected behaviors. For Sujit Datta, a ...

Separating things and then putting them back together is a common principle in industrial food production. Agricultural raw materials are broken down into their individual constituents, such as proteins, starches and fats, ...

The universe has been having fewer and fewer stellar "babies." Over the past 4.5 billion years, the rate of star birth has crashed to less than half of what it once was. But here's the twist: the most essential "fuel" for ...

Data from many sources, including NASA, have shown a significant decrease in Arctic sea ice since 1979. However, the processes driving the melting and freezing of sea ice are complex, and fluctuations occur throughout the ...

For nearly 80 years, physicists have relied on a thought experiment created by Richard Feynman to predict how quantum particles behave. For the first time, researchers in China have tested this trick directly in the lab.

Europe is no stranger to powerful windstorms, but some storms capable of causing serious damage have an unusual origin. Tropical cyclones can occasionally travel north from lower latitudes and reach Europe, where they can ...

Astronomers using the James Webb Space Telescope have identified one of the most distant exploding stars ever confirmed. The supernova, SN 2023aeaf, was found at a redshift of 3.195—so far away that its light has been traveling ...

Astronomers may have finally solved the mystery behind a nearly two-decade-old cosmic explosion that seemed to break the rules of physics. The energy output of a powerful gamma-ray burst, GRB 061201, discovered in 2006, did ...

The ancient Romans were a deeply religious and superstitious people, worshiping dozens of cults—some official and others secretive. One of these was dedicated to Sabazios, a deity from Thrace and Phrygia (regions spanning ...

A new study led by Flinders University has flipped the historical narrative about Australia's thylacine, finding the native apex predator known as the "Tasmanian tiger" was significantly different from the wolves and wild ...
