With their slender bodies and long front legs, Miracinonyx trumani—often nicknamed the "American cheetah"—was long thought to be a North American analog of the African big cat. But in a new study published in the journal Current Biology, researchers reveal that the extinct cat
As the electronics in our technology keep shrinking, traditional silicon-based chips are approaching their fundamental physical limits. Yet the wires connecting them might be able to shrink beyond conventional dimensions, as scientists have created one of the longest
The Pantone color of the year for 2026 is white. It's called Cloud Dancer, which is described as a "lofty white." This choice reflects a growing trend away from color in our visual world.
Using more than 15 years of observations from the Parkes radio telescope, astronomers detected three rotational glitches in the pulsar PSR J1637−4642—a young neutron star that had shown no signs of glitches since its discovery. The three glitches included one that changed its
Autocracy wasn’t inevitable in early civilizations. But when riches were there to monopolize, strongmen and inequalities emerged
Several space missions are searching for extraterrestrial life, which could come in the form of microbes The post Many Space Missions Are Searching for Life Beyond Earth—But Are We Prepared for the Fallout If They Succeed? appeared first on Nautilus .
Collectively intelligent bricks figure out if they’re in a boat, chair or guitar
Germany's Isar Aerospace launched a rocket into orbit from Norway on Saturday as Europe races to boost its ability to economically send satellites into space independently of the United States.
Indonesia’s dangerous peat fires are surging early in the 2026 fire season as a strengthening El Niño and severe drought dry out wetlands that can burn underground for months. These slow smoldering fires are especially destructive because they release far more fine particles
Acrid smoke hung heavily over the Malaysian town of Serian, seeping into homes and cloaking roadside stalls, as residents navigated an air-quality emergency fueled by transboundary haze from Indonesia's raging fires.
Princeton researchers have tested an AI system that can monitor and control fusion plasma in milliseconds, reacting far faster than a human operator. In one experiment, it predicted a damaging instability about 200 milliseconds before it appeared and adjusted the plasma to stop
Researchers may have found a new way to weaken glioblastoma’s defenses against treatment. Blocking a protein called SET prevented tumors from forming in preclinical models, while targeting related proteins made cancer cells more vulnerable to radiation. The strategy works by
Scientists used Earth’s magnetic field and atmosphere as a planet-sized detector to search for some of the lightest proposed forms of dark matter. The approach dramatically improved limits on ultralight axions and uncovered several intriguing dark photon signals that still need
Archaeologists have identified tiny 80,000-year-old projectile points in Uzbekistan that may have been used like arrowheads. Their size, design, and impact damage closely resemble weapons found much later at a Homo sapiens site in France. The discovery suggests sophisticated
Heart disease and chronic kidney disease can accelerate one another, but new guidelines say simple screening and early treatment could substantially reduce the risks. Blood and urine tests, combined with proven heart and kidney therapies, may help catch problems sooner and
A common frog found across Ecuador and Colombia has finally been recognized as its own species after more than a century of mistaken identity. Museum specimens from the 1800s helped scientists reveal that Pristimantis milpe had been hiding in plain sight all along.
Scientists have found evidence that vulnerability to rheumatoid arthritis may begin before birth. Finger joints commonly affected by the disease develop with different tissue structures and larger populations of specialized fibroblasts than joints that are usually spared. Those
Conformational changes in proteins are vital to their function yet remain challenging for state-of-the-art artificial intelligence, such as AlphaFold3, to predict. Researchers at the Institute for Molecular Science (IMS), and the Graduate University for Advanced Studies,
A study led by the University of Jyväskylä in Finland evaluated, for the first time, an ecological threshold for the amount of clearcutting in boreal forests. According to the results, maintaining populations of bird species specialized in old-growth forests requires either a
Scientists in Japan have identified a natural compound found in blueberries, grapes, and other berries that may help muscle cells burn excess fat instead of storing it. The compound, pterostilbene, reduced abnormal fat buildup in cultured mouse muscle cells by boosting fat
Astronomers have found two clouds of hydrogen near the Whirlpool galaxy that appear to contain almost no stars. The clouds, discovered with China's FAST radio telescope, each contain roughly 3 million times the mass of the sun in hydrogen but have no detectable optical
The human-animal bond is often so strong that pet owners may delay or forgo medical treatment or leave a health care facility against medical advice if they have no one to care for their pet at home. A perspective paper published in the New England Journal of Medicine explains
Here's a novel idea for countering the painful side effects of chemotherapy: Beforehand, take the hallucinogenic drug found in magic mushrooms.
In 1974, Stephen Hawking made a prediction that transformed our understanding of black holes. Black holes, he showed, are not truly black: They slowly lose energy through a quantum process now known as Hawking radiation. The lighter the black hole, the faster it evaporates.
New research has found that tree species diversity can play a crucial role in protecting forests from the growing threat of extreme climate events. The study analyzed data from 88,116 separate forest plots across the United States to investigate the impact of "compound climate
