This powerful drug combo cuts prostate cancer deaths by 40%19:28 A new drug combo of enzalutamide and hormone therapy has been shown to extend survival for men with recurring prostate cancer, reducing death risk by over 40%. The study followed more than 1,000 patients worldwide and was led by Cedars-Sinai researchers. Experts call it a game changer that’s likely to reshape treatment guidelines for aggressive prostate cancer. Cancer patients who got a COVID vaccine lived much longer19:28 A groundbreaking study reveals that cancer patients who received a COVID-19 mRNA vaccine within 100 days of starting immunotherapy lived dramatically longer than those who didn’t. Researchers from the University of Florida and MD Anderson Cancer Center discovered that the vaccine’s immune-activating properties may boost cancer-fighting responses, acting like a nonspecific “flare” that reawakens t… Astronomers discover a gigantic bridge of gas connecting two galaxies19:28 Researchers from The University of Western Australia node at the International Centre for Radio Astronomy Research (ICRAR) have uncovered a colossal bridge of neutral hydrogen gas linking two dwarf galaxies, which spans an astonishing 185,000 light-years between galaxies NGC 4532 and DDO 137, located 53 million light-years from Earth. A clue to ancient life? What scientists found inside Mars’ frozen vortex19:28 Mars’ north polar vortex locks its atmosphere in extreme cold and darkness, freezing out water vapor and triggering a dramatic rise in ozone. Scientists found that the lack of sunlight and moisture lets ozone build up unchecked. This discovery, made with data from ESA’s and NASA’s orbiters, could reveal clues about Mars’ past atmospheric chemistry and potential for life. These 80-year-olds have the memory of 50-year-olds. Scientists finally know why19:28 SuperAgers defy normal aging by keeping sharp memories and healthy brains well into their 80s. Northwestern scientists discovered that these individuals either resist the buildup of harmful brain proteins or remain unaffected by them. Their brains stay structurally youthful, and their strong social lives may help protect cognition. The findings could inspire new ways to delay or prevent dementia. This tiny laser could transform how we see and sense the world19:28 Researchers from NTNU and EPFL have unveiled a compact, low-cost laser that outperforms current models in speed, control, and precision. Built using microchip technology, it can be mass-produced for use in everything from Lidar navigation to gas detection. The design’s stability and easy frequency tuning could transform communication and sensing technologies. A hidden gene could triple wheat yields19:28 Researchers discovered the gene that gives a rare wheat variety its unusual “triple-grain” trait. When switched on, the gene helps wheat flowers produce extra grain-bearing parts. The finding could allow scientists to grow new, high-yield crops to meet global food demand. It’s a simple genetic change with world-changing potential. Breakthrough cancer therapy stops tumor growth without harming healthy cells8:18 Scientists have found a new way to stop cancer growth without damaging healthy cells. Researchers from the Francis Crick Institute and Vividion Therapeutics discovered a compound that blocks the signal telling cancer cells to grow and divide. The treatment worked in mice with lung and breast tumors and didn’t cause harmful side effects seen in earlier drugs. Now entering human trials, this breakt… How cutting lipids could starve breast cancer8:18 Researchers found that triple-negative breast cancer cells are “addicted” to lipids, a feature tied to obesity. By studying mice, they discovered that high lipid levels alone accelerate tumor growth. Lowering these fats slowed cancer progression, suggesting that lipid-lowering treatments could help. The findings also caution against high-fat diets such as keto for patients with obesity. Even “diet” soda may be quietly damaging your liver, scientists warn7:14 Both regular and “diet” soft drinks may be far worse for liver health than believed. A massive study of over 120,000 participants found that consuming more than one can a day of either sugar-sweetened or low/no-sugar beverages sharply increased the risk of metabolic-associated steatotic liver disease (MASLD) and even liver-related deaths. Surprisingly, “diet” drinks carried similar or higher risk… Something mysterious is lighting up the Milky Way. Could it be dark matter?6:08 Scientists at Johns Hopkins may be closing in on dark matter’s elusive trail, uncovering a mysterious gamma ray glow at the heart of our galaxy that could signal unseen matter colliding — or perhaps the frantic spin of dying stars. Using advanced simulations that account for the Milky Way’s ancient formation, researchers found a near-perfect match between theoretical and observed gamma ray maps, … Einstein’s overlooked idea could explain how the Universe really began5:04 Researchers have unveiled a new model for the universe’s birth that replaces cosmic inflation with gravitational waves as the driving force behind creation. Their simulations show that gravity and quantum mechanics may alone explain the structure of the cosmos. This elegant approach challenges traditional Big Bang interpretations and revives a century-old idea rooted in Einstein’s work. Surgery beats Ozempic for long-term health, Cleveland Clinic finds18.října Weight-loss surgery dramatically outperformed GLP-1 medications in improving longevity and reducing heart, kidney, and eye complications for people with obesity and diabetes. Over 10 years, patients lost far more weight and required fewer medications. Experts say surgery continues to offer survival advantages even in the age of potent obesity drugs. Stanford scientists grow thousands of mini human brains using common food additive18.října Stanford scientists have solved a long-standing challenge in growing brain organoids by using a simple food additive to keep them from sticking together. The breakthrough enables the production of thousands of identical mini-brains at once, making large-scale testing and research possible. This leap could revolutionize how we study brain development and screen drugs for side effects. The discover… Scientists just debunked the calcium and dementia myth18.října A long-term Australian study found that calcium supplements do not raise dementia risk in older women, countering previous fears. The research followed more than 1,400 participants for nearly 15 years and revealed no harmful cognitive effects. Scientists say these results should reassure those using calcium to prevent osteoporosis, though more research is needed across broader populations. |
