This simulation reveals what really happens near black holes11:42 Black holes are among the most extreme objects in the universe, and now scientists can model them more accurately than ever before. By combining Einstein’s gravity with realistic behavior of light and matter, researchers have built simulations that closely match real astronomical observations. These models reveal how matter forms chaotic, glowing disks and launches powerful outflows as it falls i… Subaru Telescope reveals a hidden giant planet10:31 Astronomers have uncovered a massive hidden planet and a rare “failed star” by combining ultra-precise space data with some of the sharpest ground-based images ever taken. Using the Subaru Telescope in Hawaiʻi, the OASIS survey tracked subtle stellar wobbles to pinpoint where unseen worlds were lurking—then captured them directly. This AI finds simple rules where humans see only chaos8:20 A new AI developed at Duke University can uncover simple, readable rules behind extremely complex systems. It studies how systems evolve over time and reduces thousands of variables into compact equations that still capture real behavior. The method works across physics, engineering, climate science, and biology. Researchers say it could help scientists understand systems where traditional equati… Parkinson’s breakthrough changes what we know about dopamine8:20 A new study shows dopamine isn’t the brain’s movement “gas pedal” after all. Instead of setting speed or strength, it quietly enables movement in the background, much like oil in an engine. When scientists manipulated dopamine during movement, nothing changed—but restoring baseline dopamine levels made a big difference. The finding could reshape how Parkinson’s disease is treated. A traditional Brazilian plant shows unexpected strength against arthritis7:14 A Brazilian study has confirmed that Joseph’s Coat, a plant used for generations in folk medicine, can significantly reduce inflammation and arthritis symptoms in lab tests. Researchers observed less swelling, healthier joints, and signs of tissue protection. Just as important, the extract showed a promising safety profile at tested doses. The discovery could pave the way for new plant-based anti… Study links full-fat cheese to lower dementia risk6:08 Eating full-fat cheese and cream may be associated with a lower risk of dementia, according to a large study that tracked people for more than 25 years. Those who consumed higher amounts of these foods developed dementia less often than those who ate little or none. Interestingly, low-fat dairy products did not show the same pattern. Researchers caution that the findings show an association, not … Global warming could trigger the next ice age6:08 Scientists have uncovered a missing feedback in Earth’s carbon cycle that could cause global warming to overshoot into an ice age. As the planet warms, nutrient-rich runoff fuels plankton blooms that bury huge amounts of carbon in the ocean. In low-oxygen conditions, this process can spiral out of control, cooling Earth far beyond its original state. While this won’t save us from modern climate c… Hidden seismic signals hint at a tsunami threat in Alaska16:56 Researchers studying a massive landslide in Alaska have detected strange seasonal seismic pulses caused by water freezing and thawing in rock cracks. These faint signals could become an important early clue to changes that might someday trigger a dangerous landslide-driven tsunami. Ancient sewers expose a hidden health crisis in Roman Britain16:56 Sediments from a Roman latrine at Vindolanda show soldiers were infected with multiple intestinal parasites, including roundworm, whipworm, and Giardia — the first time Giardia has been identified in Roman Britain. These parasites spread through contaminated food and water, causing diarrhea, weakness, and long-term illness. Even with sewers and communal toilets, infections passed easily between s… Science says we’ve been nurturing “gifted” kids all wrong16:56 A major international review has upended long-held ideas about how top performers are made. By analyzing nearly 35,000 elite achievers across science, music, chess, and sports, researchers found that early stars rarely become adult superstars. Most world-class performers developed slowly and explored multiple fields before specializing. The message is clear: talent grows through variety, not narr… A new tool is revealing the invisible networks inside cancer16:56 Spanish researchers have created a powerful new open-source tool that helps uncover the hidden genetic networks driving cancer. Called RNACOREX, the software can analyze thousands of molecular interactions at once, revealing how genes communicate inside tumors and how those signals relate to patient survival. Tested across 13 different cancer types using international data, the tool matches the p… Scientists unlocked a superconductor mystery under crushing pressure12:27 Superconductors promise loss-free electricity, but most only work at extreme cold. Hydrogen-rich materials changed that—yet their inner workings remained hidden because they only exist under enormous pressure. Now, researchers have directly measured the superconducting state of hydrogen sulfide using a novel tunneling method, confirming how its electrons pair so efficiently. The discovery brings … Scientists found climate change hidden in old military air samples12:27 Old military air samples turned out to be a treasure trove of biological DNA, allowing scientists to track moss spores over 35 years. The results show mosses now release spores up to a month earlier than in the 1990s. Even more surprising, the timing depends more on last year’s climate than current spring conditions. It’s a striking example of how fast ecosystems are adjusting to a warming world. Astrophysicists map the invisible universe using warped galaxies12:27 By studying tiny distortions in the shapes of distant galaxies, scientists mapped dark matter and dark energy across one of the largest sky surveys ever assembled. Their results back the standard picture of the universe and show that even archival telescope images can unlock cosmic mysteries. Is a vegan diet safe for kids? A huge study has answers12:27 A major new meta-analysis finds that vegetarian and vegan diets can support healthy growth in children when properly planned. Kids on plant-based diets often had better heart health markers, including lower “bad” cholesterol, and consumed more fiber and vitamins. But the study also flagged common nutrient gaps—especially vitamin B12 and calcium—without supplementation. Experts say plant-based eat… |
