An international team of astronomers has achieved a first in probing the early universe, using the James Webb Space Telescope (JWST), detecting a supernova—the explosive death of a massive star—at an unprecedented cosmic distance. [...]
Artificial intelligence is everywhere. In fact, each reader of this article could have multiple AI apps operating on the very device displaying this piece. [...]
For the first time, scientists have observed the iconic Shapiro steps, a staircase-like quantum effect, in ultracold atoms. [...]
In October 2024, Conservative leader Kemi Badenoch declared herself a "net zero skeptic," but "not a climate skeptic." Most recently she doubled down, announcing plans to scrap the 2030 ban on new petrol cars in a 900-word Sunday Telegraph article that did not mention climate change once. [...]
The gut microbiome is intimately linked to human health and weight. Differences in the gut microbiome—the bacteria and fungi in the gut—are associated with obesity and weight gain, raising the possibility that changing the microbiome could improve health. But any given person's gut contains hundreds of different microbial species, making it difficult to tell which species could help. [...]
Like much of the Western world, Canada is facing a crisis in waste disposal as landfills reach their capacity. In Ontario, a live countdown gives municipal landfills just eight more years before they are full. We urgently need to reduce our garbage. [...]
Tiny tubes of carbon that emit single photons from just one point along their length have been made in a deterministic manner by RIKEN researchers. Such carbon nanotubes could form the basis of future quantum technologies based on light. [...]
Graphene is often described as a wonder material. It is strong, electrically conductive, thermally efficient, and remarkably versatile. Yet despite more than a decade of excitement, many graphene-based technologies still struggle to move beyond the laboratory. [...]
Endangered penguins living off South Africa's coast have likely starved en masse due to food shortages, a study said, with some populations dropping by 95% in just eight years. [...]
A collaboration between the University of Huddersfield's Archaeogenetics Research Group and the University of Southampton's Center for Maritime Archaeology, has clarified the first settlement of New Guinea and Australia by modern humans, Homo sapiens—refining our understanding of the origins of seafaring and maritime mobility. [...]
When black holes collide, the impact radiates into space like the sound of a bell in the form of gravitational waves. But after the waves, there comes a second reverberation—a murmur that physicists have theorized but never observed. [...]
Five minutes of training can significantly improve people's ability to identify fake faces created by artificial intelligence, research published in the journal Royal Society Open Science shows. [...]
In a study published in Latin American Antiquity, Dr. Julien Hiquet and Dr. Rémi Méreuze analyzed the remains of a unique mosaic-style patolli game board discovered in the Classic Period city of Naachtun, Guatemala. [...]
Scientists have discovered the single largest dinosaur track site in the world in Carreras Pampa, Torotoro National Park, Bolivia. The tracks were made about 70 million years ago, in the late Cretaceous Period, by theropods—bipedal three-toed dinosaurs—with bird tracks also present in this ancient beach scene. [...]
The Maryland Commission on Climate Change released its 2025 annual report on Dec. 23, offering a new set of recommendations aimed at helping the state meet aggressive greenhouse gas reduction goals while preparing communities for the growing impacts of climate change. [...]
From morning glories spiraling up fence posts to grape vines corkscrewing through arbors, twisted growth is a problem-solving tool found throughout the plant kingdom. Roots "do the twist" all the time, skewing hard right or left to avoid rocks and other debris. [...]
A small, icy moon of Saturn called Enceladus is one of the prime targets in the search for life elsewhere in the solar system. A new study strengthens the case for Enceladus being a habitable world. [...]
Hydrogen peroxide is widely used in everyday life, from disinfectants and medical sterilization to environmental cleanup and manufacturing. Despite its importance, most hydrogen peroxide is still produced using large-scale industrial processes that require significant energy. Researchers are thus seeking cleaner alternatives. [...]
On Dec. 19, at the Target store on Riverside Boulevard, stacks of plastic bags sat prominently at checkout counters—the only visible option available for shoppers at both self-checkout kiosks and traditional lanes. [...]
Like a phoenix rising from the ashes, our skin tissue—and in fact many types of epithelial tissue that lines and covers the body's organs—can respond to death and destruction with a burst of regeneration. This phenomenon, known as compensatory proliferation, was first described in the 1970s in fly larvae, which regrew fully functional wings after their epithelial tissue had been severely damaged by high-dose radiation. Since then, this surprising ability has been documented in many species, including humans, yet its molecular basis has remained unclear. [...]
Flash flood warnings were in effect in Los Angeles and most of southern California on Wednesday as one of the worst Christmas storms in recent memory brought heavy rain and fears of deadly mudslides. [...]
Imaging technology has transformed how we observe the universe—from mapping distant galaxies with radio telescope arrays to unlocking microscopic details inside living cells. Yet despite decades of innovation, a fundamental barrier has persisted: capturing high-resolution, wide-field images at optical wavelengths without cumbersome lenses or strict alignment constraints. [...]
Astronomers have used the Keck Observatory's DEIMOS multi-object spectrograph to observe a nearby galaxy cluster designated RXC J0032.1+1808. As a result, they found that the cluster undergoes a major merging event. The finding was presented in a research paper published December 16 on the pre-print server arXiv. [...]
Astronomers have confirmed the first known triple system in which all three galaxies host actively feeding, radio-bright supermassive black holes. [...]
Researchers have developed experimental drugs that encourage the mitochondria in our cells to work a little harder and burn more calories. The findings could open the door to new treatments for obesity and improve metabolic health. [...]
California milk cartons may lose their coveted recycling symbol, the one with the chasing arrows, potentially threatening the existence of the ubiquitous beverage containers. [...]
What's the value of one animal? When a wild animal is found badly injured, the most humane option is often euthanasia to prevent further suffering. That's what usually happens, and often for good reason. Even when the resources to rescue one animal are available, a rehabilitated animal brought back into the wild might be rejected by its group, or struggle to find food or escape predators. If it does survive, it may fail to reproduce, and leave no lasting mark on the population. [...]
During mating season, when male white-tailed deer want to get noticed by the opposite sex and warn off rivals, they rub their antlers against trees and scrape the forest floor. Then they pee on these patches. But there is more to these physical and scent markers than meets the eye—or nose. According to a new study published in the journal Ecology and Evolution, they also glow so that other deer can see them when it's dark. [...]
Christmas means different things to different people. For me, it's an opportunity to eat celebratory foods that aren't available all year round. [...]
Ever wondered why your mango tree drops fruit before it's ripe? Each season, mango growers across Australia watch helplessly as millions of mangoes fall to the ground too early. [...]
