Scientists have uncovered an elegant biophysical trick that tuberculosis-causing bacteria use to survive inside human cells, a discovery that could lead to new strategies for fighting one of the world's deadliest infectious diseases.
Proteins long known to be essential for hearing have been hiding a talent: they also act as gatekeepers that shuffle fatty molecules across cell membranes. When this newly discovered function goes haywire—due to genetic mutations, noise-induced damage, or certain medications—it

A satellite captured a recent “ring of fire” eclipse from a stunning new angle
Researchers tested whether generative AI could handle complex medical datasets as well as human experts. In some cases, the AI matched or outperformed teams that had spent months building prediction models. By generating usable analytical code from precise prompts, the systems
For the first time, scientists have mapped Uranus’s upper atmosphere in three dimensions, tracking temperatures and charged particles up to 5,000 kilometers above the clouds. Webb’s sharp vision revealed glowing auroral bands and unexpected dark regions shaped by the planet’s
Astronomers have uncovered one of the most mysterious galaxies ever found — a dim, ghostly object called CDG-2 that is almost entirely made of dark matter. Located 300 million light-years away in the Perseus galaxy cluster, it was discovered in an unusual way: not by its stars,
A common bacterium best known for causing pneumonia and sinus infections may also play a surprising role in Alzheimer’s disease. Researchers found that Chlamydia pneumoniae can invade the retina and brain, where it sparks inflammation, nerve cell death, and the buildup of
Travel and dating apps like Grindr are reshaping how some queer men in relationships negotiate sex and intimacy—often through careful discussion and agreed boundaries rather than secrecy, challenging assumptions that such encounters are reckless, according to new research from
Minnesota is struggling to achieve its climate goals despite decades of falling greenhouse gas emissions, newly released state data shows. State law requires Minnesota's electric utilities to reduce their carbon emissions to zero by 2040.
At least 1,100 dead or sick birds, mostly Canada geese, have been reported across New Jersey in an outbreak that started on Valentine's Day, according to state officials.
Passing on fundamental life lessons from parent to offspring is not unique to humans and animals. Ferns do it too. Not with words, but through pressure. By applying force at precisely the right locations, a fern tells its embryo what is up and what is down, and therefore where
An Ybor business owner closed her yoga studio repeatedly from worries over moldy, waterlogged walls. A Pinellas woman's home flooded in one hurricane, and a tree crushed her car in another. A Tampa student feared her insulin would become ineffective in extreme, hot temperatures.
Fake news generated by AI is often perceived as more credible than texts written by humans. That worries linguist Silje Susanne Alvestad. In 2017, "fake news" was chosen as the new word of the year by the Language Council of Norway. But what are the linguistic features of fake
Along with cricket, thongs and backyard barbecues, the arrival of the annual Australian Lamb ad has become synonymous with an Australian summer. What began back in 2005 as a pitch to get Australians eating more lamb has since become a yearly cultural icon that tackles an issue
When Paul Reillo learned the endangered mountain bongo antelopes that he had cared for since birth were stranded in a cargo plane on an airport tarmac ahead of their journey to a new home in Kenya, he took matters into his own hands.
Persistent concerns about poor behavior in UK secondary schools have led to the widespread implementation of disciplinary behavior management strategies. These include the use of isolation rooms, where children are sent to work alone.
New research from Adelaide University is questioning the widespread use of the term "resilience" in Australian agriculture, arguing that its overuse can place unfair pressure on individual farmers and obscure the need for systemic support. Published in the Journal of Rural
In an era of rising grocery costs, eggs remain one of the most accessible and complete protein sources for families. New research from the University of Hawai'i at Mānoa's College of Tropical Agriculture and Human Resilience (CTAHR) is investigating how chickens age to help
Inspired by the simple mechanism of a seesaw—when one side goes up, the other side goes down—researchers asked an intriguing question: Could a single molecule switch between two different roles like a seesaw? This idea led to the creation of a new type of artificial protein
Antarctica plays a crucial role in Earth's climate system by reflecting solar radiation back into space. The large white ice surfaces and clouds play a decisive role in this process. However, how clouds actually form in Antarctica, how they interact with the atmosphere and what
Advances in supercomputing have made solving a long‐standing astronomical conundrum possible: How can we explain the changes in the chemical composition at the surface of red giant stars as they evolve?
The FDA is reportedly considering broadening the types of drugs that can be sold without a prescription, a move some pharmacy experts say could raise safety risks
Hundreds of thousands of marine animals are killed every year after becoming accidentally caught in commercial fishing nets. Sharks, skates and rays are at particular risk, alongside turtles, seals, whales and dolphins, many of which are endangered.
Recurrent droughts, conflict, and changing land use have placed significant strain on pastoral populations in the dryland regions of Africa, resulting in numerous crises that require humanitarian intervention. Pastoralism is both an economic activity and a cultural identity
Space junk returning to Earth is introducing metal pollution to the pristine upper atmosphere as it burns up on re-entry, a new study has found.
Ribosomes, the cell's protein-making factories, consume large amounts of energy as they build the proteins that keep cells alive and functioning. When cells experience stress—such as lack of nutrients or sudden drops in temperature—they quickly switch into survival mode. New
