A distant star has captured astronomers' attention over the past decade, teasing them with indications that it will soon explode as a supernova. But new research shows that something else entirely is behind the star's outbursts. Rather than an impending catastrophic explosion, a previously unseen companion may be responsible for the star's behavior.
Researchers at the Department of Energy's Oak Ridge National Laboratory (ORNL) have developed an artificial intelligence framework that helps researchers use atomic force microscopes to identify important nanoscale features while autonomously targeting the most informative areas of a sample for closer study.
The surface of Mercury is filled with craters, ridges and steep cliffs. Over billions of years, as the planet's interior cooled, the planet also shrank. Just as the skin of a drying fruit wrinkles when what is inside it shrinks, Mercury's rocky surface crumpled into ridges and cliffs as its interior cooled and the planet contracted. Mercury has quite literally grown smaller with age.
Cell membranes and the proteins within them control many vital processes and play a key role in health and disease. But studying them in 3D images of cells has so far meant slow, manual work. A team from Helmholtz Munich, the Technical University of Munich (TUM) and the Biozentrum of the University of Basel has developed MemBrain v2, an AI tool that automates this task—cutting work that once took weeks down to a few hours. The study is published in Nature Methods.
Saltwater isn't something most people associate with English farmland. But in parts of eastern England, it's becoming a growing problem, not just for crops but for farm incomes too.
Deep within an ancient sinkhole lie the remains of dozens of mammoths, prehistoric wanderers who waded into the warm springs to their deaths. These deaths had long been accepted as having occurred roughly 26,000 years ago, but new dates published in the journal Quaternary Research suggest these ice-age giants were more than 160,000 years old.
Solo travel is surging—and an industry still largely built for two is taking note. Google reported in April 2026 that online searches involving "solo travel" hit an all-time high this year, with queries for "women solo travel" reaching a 15-year peak. Hilton's 2026 trends report found that 26% of travelers planned to take a trip alone this year and that nearly half said they planned to add solo days to the front or back of a family trip.
Black holes are regions of spacetime where gravity is so strong that nothing, not even light, can escape. When two black holes orbit each other and merge, they produce gravitational waves (i.e., ripples in spacetime) that can resemble those emitted by mergers involving other exotic compact objects.
Many of the drugs that target human brain chemistry, such as antidepressants, are still biologically active when they leave the body. These substances and their metabolites can persist in wastewater and eventually end up in the sea, rivers or other aquatic environments.
An eye surgeon with a passion for space since childhood predicts that as astronauts start to make journeys to the moon and Mars in the near future, eye surgery in space will eventually become a necessity.
