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

Using a tiny, acid-tolerant yeast, scientists have demonstrated a cost-effective way to make disposable diapers, microplastics, and acrylic paint more sustainable through biomanufacturing.
Some 445 million years ago, life on Earth was forever changed. During the geological blink of an eye, glaciers formed over the supercontinent Gondwana, drying out many of the vast, shallow seas like a sponge and giving an "icehouse climate" that, together with radically changed
Hydroperoxides are strong oxidants that have a significant influence on chemical processes in the atmosphere. Now, an international research team involving the Leibniz Institute for Tropospheric Research (TROPOS) has shown that these substances also form from α‑keto acids such

Vulnerable communities in the United States often face the highest risks from individual environmental burdens, such as exposure to toxic air pollutants. But new research shows that these communities are also exposed to a disproportionate number of multiple high-intensity
Organs often have fluid-filled spaces called lumens, which are crucial for organ function and serve as transport and delivery networks. Lumens in the pancreas form a complex ductal system, and its channels transport digestive enzymes to the small intestine. Understanding how
An international research team reveals new molecular mechanisms associated with pathogenic mutations in the protein transthyretin that cause transthyretin amyloidosis (ATTR), a group of fatal progressive diseases. The results, obtained thanks to a new methodological approach,

The elm zigzag sawfly has spread to 15 states in five years. Now it's attacking the tree that cities planted to replace Dutch elm disease victims.
Plant viruses pose a serious and ongoing threat to global agriculture in tropical to temperate regions. Among the most damaging are begomoviruses, a group of DNA viruses spread by whiteflies that infect many important food crops, including eggplant, tomato, pepper, cucurbit,
A research team from Osaka Metropolitan University proposed using a current-biased kinetic inductance detector with submicron 400 megapixels to image hot spots induced by a localized external stimulus over a 15 × 15 mm2 area. The team utilized a delay-line technique to trace
Crops increasingly need to thrive in a broader range of conditions, including drought, salinity, and heat. Traditional plant breeding can select for desirable traits, but is limited by the genetic variation that already exists in plants. In many crops, domestication and
