In a striking real-world experiment, flu patients spent days indoors with healthy volunteers, but the virus never spread. Researchers found that limited coughing and well-mixed indoor air kept virus levels low, even with close contact. Age may have helped too, since middle-aged
Scientists have used CRISPR to give the goldenberry a modern makeover, shrinking the plant by about a third and making it easier to farm. Goldenberries are tasty and nutritious but notoriously unruly, with bushy plants that complicate harvesting. By editing a few key genes and
A rapid climate collapse during the Late Ordovician Mass Extinction devastated ocean life and reshuffled Earth’s ecosystems. In the aftermath, jawed vertebrates gained an unexpected edge by surviving in isolated marine refuges. Over millions of years, they diversified into many
Scientists have discovered an enormous stream of super-hot gas erupting from a nearby galaxy, driven by a powerful black hole at its center. The jets stretch farther than the galaxy itself and spiral outward in a rare, never-before-seen pattern. NASA’s James Webb Space
Scientists have identified a brand-new species of worm living in the Great Salt Lake, marking only the third known animal group able to survive its extreme salinity. The species, named Diplolaimelloides woaabi with guidance from Indigenous elders, appears to exist only in this
Charophytes are extremely beneficial to lakes, improving water quality and biodiversity. However, their abundance was found to decline in many lakes without clear signs of eutrophication during recent decades.
Rising trade frictions over the past decade have sparked urgent questions about their long-term impact on global economies. The U.S. now applies tariffs of 66.4% on Chinese exports, which is higher compared to the average rate of 19.3%, while China retaliates with a 58.3%
For more than three decades, DHS provided vital demographic and health data on population, health, HIV, and nutrition in over 90 countries. Its termination leaves major gaps in tracking the UN Sustainable Development Goals (SDGs), particularly in low- and middle-income countries.
Enzymes are the molecular machines that power life; they build and break down molecules, copy DNA, digest food, and drive virtually every chemical reaction in our cells. For decades, scientists have designed drugs to slow down or block enzymes, stopping infections or the growth
The production of clean hydrogen through water electrolysis is a promising route toward emission-free and sustainable energy technologies. However, its efficiency is still constrained by the kinetically sluggish oxygen evolution reaction (OER). This reaction requires high
An international group of researchers says that biodiversity conservation and scientific research are not benefiting from the vast knowledge about the world's plants held by botanic gardens, because of fragmented data systems and a lack of standardization.
The X-Ray Imaging and Spectroscopy Mission (XRISM), a joint mission between the Japanese Aerospace Exploration Agency (JAXA) and NASA, launched on Sept. 7th, 2023. Its advanced imaging filters and spectrometers were designed to study black holes and neutron stars and detect the
The Thwaites and Pine Island glaciers, located in the Amundsen Sea sector of the West Antarctic Ice Sheet (WAIS), are among the fastest-melting glaciers on Earth. Together, they are losing ice more rapidly than any other part of Antarctica, raising serious concerns about the
At temperatures where most molecular movement ceases, certain organic crystals begin their self-healing journey.
Air pollution regulations in the United States are intended to protect public health, but a new study has found that they also carry an unexpected cost: higher interest rates on the bonds used by counties to fund schools, hospitals, and infrastructure. When a county falls out
Four ISS crew members are set to touch down on Thursday after NASA announced the first medical evacuation in the space station’s history
Happy new year! If you're a redhead, the pigments in your hair are protecting you from cellular damage. A post-stroke injection comprising regenerative nanomaterial can protect the brain. And researchers have developed a method to extract rare earth elements from coal tailings.
Crystals hidden in Australia’s oldest rocks have revealed new clues about how Earth and the Moon formed. The study suggests Earth’s continents didn’t begin growing until hundreds of millions of years after the planet itself formed. When scientists compared the rocks with Moon
Although the gut renews itself constantly, its stem cells accumulate age-related molecular changes that quietly alter how genes are switched on and off. Scientists found that this “epigenetic drift” follows a clear pattern and appears in both aging intestines and most colon
Australian authorities declared a state of disaster on Saturday after bushfires destroyed houses and razed vast belts of forest in the country's southeast.
Neither a square nor prime number, 2026 is still intriguing
The old saying goes: Money can't buy happiness. But it sure can make or break a relationship.
Pandora, the latest in a long portfolio of University of Arizona's space science missions, has cleared its last major milestone on its journey into space. This week, Pandora—a satellite about the size of fridge—was mounted inside the launch vehicle, a SpaceX Falcon 9 rocket.
NASA crewmembers aboard the International Space Station (ISS) could return to Earth as soon as Thursday, the US space agency said, after a medical emergency prompted the crew to return from their mission early.
Gale-force winds and storms barreled through northern Europe on Friday, claiming more lives, causing travel mayhem, shutting schools, and cutting power to hundreds of thousands in freezing temperatures.
