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.
As drones survey forests, robots navigate warehouses and sensors monitor city streets, more of the world's decision-making is occurring autonomously on the edge—on the small devices that gather information at the ends of much larger networks.
Sleep isn’t just about feeling rested—it may be one of the strongest predictors of how long you live. Researchers analyzing nationwide data found that insufficient sleep was more closely tied to shorter life expectancy than diet, exercise, or loneliness. The connection was
New research shows that aging blood can accelerate Alzheimer’s-like changes in the brain, while younger blood may offer protection. In mouse experiments, older blood worsened memory performance and increased toxic protein buildup linked to the disease. The study also uncovered
Pancreatic cancer is notoriously hard to treat, often resisting therapies that target its most common mutations. Researchers have now uncovered a hidden three-part loop that fuels tumor growth, involving the cancer drivers SRSF1, AURKA, and MYC. By targeting just one part of
Astronomers have uncovered the long-hidden cause behind Betelgeuse’s strange behavior: a small companion star carving a visible wake through the giant’s vast atmosphere. Using nearly eight years of observations from NASA’s Hubble Space Telescope and ground-based observatories,
Hubble has revealed a strange cosmic object called Cloud-9, a dark matter–dominated cloud with no stars at all. Scientists believe it is a “failed galaxy,” a leftover building block from the early Universe that never lit up. Its discovery confirms long-standing theories about

Sugar-loving mouth bacteria create acids that damage teeth, but arginine can help fight back. In a clinical trial, arginine-treated dental plaque stayed less acidic, became structurally less harmful, and supported more beneficial bacteria. These changes made the biofilms less
In order to understand currents, tides and other ocean dynamics, scientists need to accurately capture sea surface height, or a snapshot of the ocean's surface, including peaks and valleys due to changes in wind, currents and temperature, at any given moment. In order to more

Cutting down boreal forest and sinking the felled trees in the depths of the Arctic Ocean could remove up to 1 billion tonnes of carbon dioxide from the atmosphere each year – but it could come at a cost to the Arctic ecosystem
