Rancher BJ Fuchs hasn't been able to let his guard down as wildfires advanced in Canada's Alberta province, so far sparing his farm in Shining Bank but scorching forests and grasslands all around it.

A crucial radar antenna on a European spacecraft bound for Jupiter is no longer jammed.

Let's start with the bad news. Current conservation practices likely won't do enough to save the black tern, a migratory bird species that nests in the northern U.S. and southern Canada, from disappearing.

Scientists at Southampton University say they accidentally stumbled upon the largest explosion ever recorded in the cosmos. Known as AT2021lwx, Philip Wiseman, a lead researcher at the university says his team believed it happened around 8bn years ago. Wiseman said it was only detectable from the earth because of the sheer magnitude of the explosion, which they believe was caused by a giant gas...

Scientists have detected the ripple effects of small ground-level explosions 100 kilometers up in ionized layers of the upper atmosphere. The result suggests the remote sensing technique could be used to monitor explosive events—natural or human—hundreds of times smaller than before. “It was a big surprise to me,” says Jihye Park, a geodetic scientist at Oregon State University...

The scalloped hammerhead shark is most comfortable in warm water, but hunts by diving deep into the cold depths to hunt squid and other prey. A new study from the Hawai’i Institute of Marine Biology has found that the sharks stay warm by closing their gills in their dives to prevent heat...

Bob McDonald's blog: Nature-inspired robots could help us get around and into extreme icy terrains to explore subsurface moon...

It was only last October that telescopes spotted a gamma ray burst—caused by the collapse of a black hole—that was so powerful astronomers quickly dubbed it BOAT, for “Brightest of all Time.” That was a fair enough nickname for such a sensational emission—for a little while anyway. But BOAT has just been busted to second most powerful. According to a new study...

Scientists have precisely identified base pairs of the human genome that remained consistent over millions of years of mammalian evolution, and which play a crucial role in human disease. The team analyzed the genomes of 240 mammals, including humans and identified base pairs that were 'constrained' -- meaning they remained generally consistent -- across mammal species over the course of...

Ruminants like cows have developed an unusual way of digesting their food: they ingest plants, give them a rough chewing and then swallow the half-chewed mash before regurgitating it repeatedly and continuing to chew. This has clear advantages: the regurgitated mushy food contains much less hard grit, sand and dust than the food that they first ingested. This protects the teeth from being ground...

Physicists measured the flux of interplanetary dust around Saturn. The researchers concluded that the planet's rings formed less than 400 million years ago, making them much younger than Saturn itself.

Students are positive towards AI tools such as ChatGPT in education, but 62 percent believe that using chatbots during exams is cheating. However, where the boundary for cheating lies is highly unclear.

Ruminants like cows have developed an unusual way of digesting their food: they ingest plants, give them a rough chewing and then swallow the half-chewed mash before regurgitating it repeatedly and continuing to chew. This has clear advantages, as a research team including the University of Göttingen has shown: the regurgitated mushy food contains much less hard grit, sand and dust than the food...

The spread of drug-resistant microbes has become a global health concern that threatens our ability to treat infections. The widespread use of antimicrobials in livestock, such as swine farms, exacerbates this problem. Therefore, we need surveillance systems to monitor these microbes to support the public health authorities. To this end, researchers have tracked the antimicrobial resistance of...

There is always something growing inside the gated courtyard of the L.A. Catholic Worker Hospitality Kitchen, the Skid Row food distribution center better known as the "Hippie Kitchen."

Polymer-based materials are almost everywhere, reaching even the deepest regions of the oceans, and their global production outpaces recycling, leading to the generation of tremendous amounts of water pollution with microplastics. These tiny polymer particles not only release chemicals but also reduce the number of bacteriophages.

A new study led by physicist Sascha Kempf at the University of Colorado Boulder has delivered the strongest evidence yet that Saturn's rings are remarkably young—potentially answering a question that has boggled scientists for well over a century.

A lot has changed since the last Space Age. Unlike the days of Sputnik, Vostok, Mercury, and Apollo, the current era is not defined by two superpowers constantly vying for dominance and one-upmanship. More than ever, international cooperation is the name of the game, with space agencies coming together to advance common exploration and science goals.

The long-anticipated return to the London office is underway—but this does not mean a return to the traditional office-based working culture. Working practices are now predominantly characterized by a hybrid approach, and this transformation of at least some sectors to a "new normal" constitutes a significant paradigm shift in the world of work.

A team of scientists from the Department of Energy's Ames National Laboratory have developed a way to collect terahertz imaging data on materials under extreme magnetic and cryogenic conditions. They accomplished their work with a new scanning probe microscope.

Modern dog breeds that are genetically more distant from wolves have a relatively larger brain size compared to ancient breeds that are thousands of years old, according to the findings of Hungarian and Swedish researchers. The increase in brain size cannot be attributed to the roles or life history characteristics of the breeds, suggesting that it is likely influenced by urbanization and a more...

The spiral-shaped bacteria Helicobacter pylori are common and troublesome.

The Murujuga rock art, the world’s largest and oldest collection of petroglyphs, has survived 40,000 years or so out in the open on a finger of land extending from Australia’s northwestern coast. “Murujuga is the most important rock art site in the world,” says Michel Lorblanchet, an archaeologist at CNRS, the French national research agency, who is noted for his work on European...
