Many of the drugs that target human brain chemistry, such as antidepressants, are still biologically active when they leave the body. These substances and their metabolites can persist in wastewater and eventually end up in the sea, rivers or other aquatic environments.
Scientists found that the 3D organization of DNA is disrupted in several types of brain cells affected by Alzheimer’s disease, altering how important genes are switched on and off. The discovery reveals a previously underexplored layer of the disease that could open new paths for understanding and eventually treating Alzheimer’s.
An eye surgeon with a passion for space since childhood predicts that as astronauts start to make journeys to the moon and Mars in the near future, eye surgery in space will eventually become a necessity.
A massive worldwide survey of physicists has revealed surprisingly little agreement about some of the universe’s biggest mysteries. No majority backed the standard cosmological model, a leading explanation for dark matter, or any single theory of quantum gravity. One area of stronger agreement stood out: 68% said the Big Bang does not necessarily represent the beginning of time. Researchers say the divisions show just how alive and unsettled the frontiers of physics remain.
Researchers from the Ningbo Institute of Materials Technology and Engineering (NIMTE) of the Chinese Academy of Sciences (CAS), in collaboration with researchers from the Technical Institute of Physics and Chemistry of CAS, have developed a coumarin-linked covalent organic framework (COF) that enables high-efficiency photocatalytic water splitting for hydrogen production.
We've found more than 5,500 exoplanets so far. Dozens of them are in the habitable zones of their parent stars, where, at least in theory, they could host an ocean. But we've never definitively found a liquid ocean on another planet.
Most men may be missing an important dietary clue about prostate cancer. A new survey found that only 20% knew research has linked dairy consumption with increased prostate cancer risk, while 66% said they would consider avoiding dairy after learning about the connection. Studies have also associated plant-based diets with substantially lower risks of prostate cancer, progression, and recurrence.
The Indian and Pacific oceans have been climatically linked for centuries, but scientists say that connection is now breaking down in an exceptional way. Ancient climate records suggest volcanoes disrupted the relationship in the past, while today human-caused warming appears to be driving a much more unusual shift.
Scientists are combining an electron microscope with a quantum computer to squeeze far more information from each electron. The approach could reveal faint details with fewer electrons, helping protect fragile samples that conventional microscopy can damage.
An international team, including researchers from the University of Minnesota Twin Cities, has reached a major milestone in "precision cosmology" by measuring the amount of helium created in the universe's first five minutes with unprecedented accuracy.
Scientists have engineered yeast to turn PET plastic and agricultural waste into ingredients for protein-rich, 3D-printed cookies called µBites. Developed partly for NASA’s Deep Space Food Challenge, the system can produce proteins, fats, vitamins, and even vanilla flavoring from waste materials. Researchers hope the unusual technology could eventually help address both plastic pollution and food insecurity, while also supplying food in extreme environments such as deep-space missions.
Researchers have experimentally demonstrated the optical Magnus effect for the first time, revealing that a tightly focused laser interacts most strongly with an atom slightly away from the beam’s center. The unexpected shift is similar to the physics that makes a spinning table tennis ball curve through the air. Because lasers are used to control qubits, the effect could create errors in quantum computers, but it might also provide a new way to couple qubits together.
A new study tries to map why humans can experience beauty collectively
AI analysis of 400,000 Reddit posts found that users of drugs such as Ozempic, Wegovy, Mounjaro, and Zepbound reported unexpected symptoms including menstrual changes, chills, hot flashes, and fatigue. Researchers cannot say the medications caused these problems, but the patterns may reveal overlooked signals worth studying.
Quick factsWhat it is: The nebula LHA 120-N44Where it is: 160,000 light-years away, in the constellation DoradoWhen it was shared: Sept. 3, 2026It looks like a gigantic hole punched through a cloud, but this spectacular new image from the Hubble Space Telescope captures something more complicated: a cosmic cycle of destruction and creation, with one generation of stars tearing apart its birthplace while simultaneously helping a new generation form.LHA 120-N44 (N44, for short) is a nebula that lies about 160,000 light-years away in the Large Magellanic Cloud, a small galaxy that orbits the Milky Way. From Earth, it appears in the constellation Dorado. This enormous, empty-looking region measu...
In a multicat household, it's common to see one cat licking another. When some people see this behavior, known as allogrooming ("allo" means "another individual"), they assume it's a sign of friendship. But is that really the case? Are there hidden, more complex reasons for why cats lick each other?While research into allogrooming is ongoing, scientists have suggested different explanations for why cats lick each other, including some social reasons and some more practical ones.Social bonding or social tension?The historical view, based on observations of free-roaming-cat colonies, was that allogrooming is a sign of affection and helps cats create and maintain bonds with other cats in their ...
Long before dinosaurs appeared on Earth, fierce predatory fish developed crushing jaws and sharp teeth to survive and diversify in ancient oceans.
A century-old mystery in Venus’s clouds just became more intriguing, as scientists calculated how strongly the unidentified material behind its dark ultraviolet patterns must absorb light. The results sharply narrow the possibilities and could help future spacecraft determine whether the mysterious substance is organic, inorganic, or something unexpected.
Ancient rocks from Western Australia suggest water was reaching deep inside Earth more than three billion years ago, long before modern plate tectonics may have fully developed. Researchers propose that water-rich pieces of crust periodically sank into the mantle through a process they call “dripduction.” The buried water then helped produce magma and volcanic eruptions.
A natural compound found in foods such as spinach, almonds, and sweet potatoes may aggravate gut inflammation in people with Crohn’s disease and ulcerative colitis because their intestines appear to handle it differently. Researchers say the finding could open the door to lower-oxalate diets or microbiome treatments tailored specifically to people with IBD.
GLP-1 drugs such as Ozempic, Wegovy, and Zepbound may increase hair-loss risk by 7% in men who are already genetically susceptible to male-pattern baldness. The findings suggest thinning hair may not be caused only by rapid weight loss and could also reflect a biological link between GLP-1 activity and hair follicles.
Scientists have uncovered a natural braking system that helps the immune system switch off inflammation and prevent harmful immune cells from building up. Boosting this pathway in people reduced inflammation-related immune changes and sped up pain relief, pointing toward potential new treatments for chronic inflammatory diseases.
Generative AI could help overwhelmed travelers organize their thoughts, compare options and complete vacation plans they might otherwise abandon, according to new research from the University of Surrey.
A multidisciplinary scientific team at the University of Malaga has developed a new technology based on magnetic nanoparticles that enables precise, rapid and reliable diagnosis of allergy to beta-lactam antibiotics, including amoxicillin and other penicillins.
