Columbia scientists discover surprising link between serotonin and heart valve disease5:40 Scientists have uncovered evidence that serotonin, the chemical best known for regulating mood, may also speed the progression of a common heart valve disease in some people. The research suggests that patients with degenerative mitral regurgitation who take SSRI antidepressants and carry a specific genetic variant may develop severe valve damage sooner, potentially requiring surgery at a younger… Why gold never tarnishes has finally been explained5:40 Gold may have a secret self-defense system that helps it resist tarnishing. Researchers discovered that atoms on gold surfaces reorganize themselves into patterns that block oxygen from reacting with the metal, suppressing oxidation by up to a trillion-fold. Beyond explaining why gold jewelry stays bright for generations, the finding could help scientists create more powerful gold-based catalysts… Yale scientists may have found how Parkinson's disease spreads through the brain4:34 Yale scientists discovered two neuron surface proteins that appear to help spread the toxic protein linked to Parkinson’s disease. Blocking these proteins in mice dramatically reduced disease progression, offering a potential new target for future therapies. Common blood pressure drug could make cancer therapy far more powerful4:34 Researchers found that the common blood pressure drug telmisartan can significantly improve the performance of the cancer drug olaparib, potentially expanding its benefits beyond patients with BRCA-related tumors. The combination is already being tested in human clinical trials after showing strong immune-boosting and anticancer effects in preclinical studies. Second pregnancy changes the brain in surprising new ways15:47 Researchers found that every pregnancy rewires the brain in its own way, with a second pregnancy bringing a different pattern of changes than the first. The discoveries could lead to better ways to recognize and treat maternal mental health challenges, including peripartum depression. Physicists finally build a quantum material predicted more than a decade ago15:47 Researchers have achieved a major milestone by creating a long-sought two-dimensional quantum material and confirming its unusual conducting edge states. The ability to control these states through strain could make the material a promising platform for future room-temperature quantum electronics. Experimental drug reverses severe fatty liver disease by repairing the gut15:47 An experimental drug called DT-109 reversed severe fatty liver disease in animal studies by repairing the gut and preventing harmful toxins from damaging the liver. The discovery could open the door to a new class of treatments for MASH and potentially other diseases tied to gut health. Tiny bubbles could revolutionize inkjet printing15:47 Ultra-fine bubbles may offer a cleaner way to perfect inkjet printing for next-generation electronics. By simply changing the number of bubbles in each droplet, researchers were able to dramatically reshape the final printed pattern without leaving behind unwanted chemical residues. Scientists warn invasive Asian mantises are threatening Europe's wildlife15:47 Two striking Asian praying mantis species that have rapidly spread across Europe have now been officially classified as invasive, raising new concerns about their impact on native wildlife. Boosted by climate change and urban environments, these fast-breeding predators are expanding northward, where they prey on native insects, pollinators, and even small vertebrates while also reducing native ma… Europe just unveiled a new rival to SpaceX’s Starship15:47 A detailed independent study found that SpaceX's Starship is every bit as revolutionary as expected, while revealing both its impressive capabilities and its biggest remaining hurdles. It also introduces an ambitious European rocket concept that could offer a very different route to affordable super heavy launches. NASA satellites are watching Earth's newest island rise from the sea15:47 A newly discovered underwater volcanic eruption north of Papua New Guinea is unfolding in one of the world's most poorly mapped ocean basins. Satellites have spotted steam plumes, ash, thermal hotspots, and huge floating pumice rafts, suggesting magma is rising surprisingly close to the surface. Scientists are now watching closely to see if the eruption creates a new island, offering a rare oppor… This electric field trick boosted heat flow by nearly 300%15:47 Researchers discovered that electricity can dramatically reshape how heat flows through certain ceramic materials, increasing heat conduction by almost threefold in a preferred direction. The unexpected result could lead to much more efficient cooling technologies and energy-saving devices. Why the human body has so many design flaws15:46 Many of the body's biggest flaws are the result of evolution building on old designs instead of starting over. Our spine, eyes, teeth, pelvis, and even certain nerves all reveal compromises that worked well enough for survival but still leave us prone to pain, injury, and disease. Structures like the appendix and ear muscles also remain because they were never harmful enough for evolution to elim… Rare fossil goose rewrites the story of New Zealand's giant birds15:46 Scientists have discovered a previously unknown fossil goose that challenges a decades-old theory about the evolution of New Zealand's birds. The find suggests the country's giant flightless geese evolved from much more recent arrivals, revealing a far more dynamic evolutionary history than once believed. Heavy marijuana smoking may increase cancer risk, researchers warn15:46 Heavy marijuana smoking may raise the risk of lung cancer and several head and neck cancers, according to growing research, but many important questions remain unanswered. Scientists are still trying to determine how much marijuana use is enough to significantly increase cancer risk. Edibles have not been linked to lung cancer so far, while the long-term effects of vaping marijuana and secondhand… |
