Rare goblin shark filmed alive for the first time in the deep sea3:58 For the first time, researchers have filmed the elusive goblin shark alive in the deep ocean where it naturally lives. The remarkable sightings greatly expand the shark's known range and depth, showing that this 125-million-year-old "living fossil" still has plenty of secrets left to reveal. Heidelberg physicists just united two opposing quantum theories3:58 A new quantum theory bridges two rival models of how impurities behave inside many-particle systems, resolving a problem that has challenged physicists for decades. The findings could reshape experiments on ultracold atoms, semiconductors, and other exotic forms of quantum matter. Scientists used AI to crack one of water's biggest mysteries3:58 Water’s odd behavior becomes even more dramatic when it is supercooled, but scientists have struggled to compare the many different ways of describing its microscopic structure. Researchers at the University of Osaka used an AI model trained on computer simulations to evaluate 16 different structural descriptors. The system identified the most effective ways to distinguish between water’s two com… Scientists finally crack nature's secret for building better cancer drugs3:58 Researchers have cracked the code behind bacteria's ability to naturally manufacture multiple versions of powerful anti-cancer drugs. The discovery could make it much easier to engineer new cancer treatments inspired by nature, including improved versions of existing medicines. 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 programmable8.července 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 honeybees8.července 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 hold8.července 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 shows8.července 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 finds8.července 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. |
