New weight loss pill beats oral Ozempic in major trial11:51 A new once-daily weight-loss pill called orforglipron delivered better weight loss and blood sugar improvements than the leading oral semaglutide in a major clinical trial. The tablet could offer a more convenient alternative to injectable drugs like Ozempic and Wegovy because it doesn't require refrigeration or special timing with meals. It's also cheaper to manufacture, which could expand acces… Ancient DNA reveals the mysterious collapse of Europe's megalith builders11:51 DNA from a 5,000-year-old French megalithic tomb reveals that the people buried before and after a population collapse were genetically unrelated, pointing to a major migration after a devastating crisis. The shift coincided with new social traditions and the disappearance of the communities that built Europe's giant stone monuments. Can't stick to a diet? Intermittent fasting may be easier than counting calories for weight loss11:51 Intermittent fasting helped people lose as much weight as calorie restriction, but without the same feeling of constantly controlling their food intake. Researchers say that difference could make fasting a more sustainable option for people who struggle with traditional diets. Creatine doesn't just build muscle. It may also help fight cancer11:51 Scientists have discovered that creatine may strengthen one of the immune system's most important cancer-fighting pathways by energizing dendritic cells that activate killer T cells. The promising results could eventually help make immunotherapy more effective, but they have not yet been tested in human patients. New AI model reveals how neutron star mergers forge heavy elements11:50 Researchers have created an AI-based simulation that makes it much faster to model how neutron star mergers produce many of the universe's heaviest elements. The new tool could improve predictions of these powerful explosions while helping scientists better connect observations in space with experiments on Earth. Incredible new material makes heat programmable3:15 A newly developed material can control and "program" heat, allowing it to direct thermal radiation, switch modes, and remember its settings without continuous power. The innovation could lead to smarter infrared sensors, better energy technologies, and memory devices that use light and heat instead of electrical charges. Bumblebees collect up to 7 times more toxic metals than honeybees3:15 Bumblebees are picking up dramatically more toxic heavy metals than honeybees, even when both species forage in the same places. Researchers warn that this hidden pollution could quietly reduce their ability to find food, reproduce, and keep colonies healthy. Schrödinger’s anthill: Quantum entanglement found in a crystal large enough to hold3:15 A centimeter-sized crystal has revealed clear signs of quantum entanglement, showing that large, everyday objects can display surprisingly deep quantum behavior. The discovery could help solve the mystery of strange metals while opening new possibilities for ultra-precise quantum sensors and other advanced technologies. The Neanderthal “love story” isn’t what the DNA actually shows3:15 Claims that Neanderthal men "preferred" Homo sapiens women may make for catchy headlines, but the underlying research does not actually show prehistoric romance. The genetic evidence only points to an uneven pattern of DNA inheritance, which could have been shaped by biology, migration, or social organization. Archaeological evidence suggests Neanderthal groups may have followed traditions where … Takeaway meals contain more salt than advertised, study finds3:15 Almost half of the takeaway meals tested contained more salt than advertised, with some dishes delivering nearly twice the recommended daily limit in a single serving. Surprisingly, classic fish and chips ranked among the lowest-salt options, while pasta, pizza, and curries were often the saltiest. AI just supercharged the race to find room temperature superconductors7.července Scientists have combined machine learning with quantum physics to discover two new superconductors and create a much faster way to search for many more. The technique could bring researchers significantly closer to the long-sought goal of a room-temperature superconductor. Scientists solve a 30-year rye pollen mystery that could transform cancer research6.července Scientists have finally solved a nearly 30-year-old mystery surrounding two unusual molecules found in rye pollen that once showed an intriguing ability to help animals fight tumors. By determining their exact 3D structures, researchers have unlocked the blueprint needed to investigate how these natural compounds interact with the immune system and which parts may be responsible for their cancer-… Millions may be getting the wrong cholesterol test6.července A new study suggests that apoB, a blood test that measures harmful cholesterol particles, is better than standard LDL cholesterol testing for deciding who needs more intensive treatment. Researchers found it could prevent more heart attacks and strokes while remaining cost-effective for the U.S. healthcare system. Streetlights are trapping thousands of pill bugs in giant “death spirals”6.července Researchers discovered that artificial streetlights can trap thousands of woodlice in mesmerizing circular "death spirals" never before seen in the wild. The surprising finding suggests that light pollution may be unintentionally altering the behavior of even the smallest ground-dwelling animals. Astronomers witness the birth of a magnetar for the first time6.července A strange "chirping" signal from a distant supernova has revealed the birth of a magnetar, confirming that these incredibly magnetic neutron stars can power the universe's brightest stellar explosions. The discovery also marks the first time Einstein's general relativity has been used to explain the mechanics of a supernova. |
