A mysterious particle overlooked for decades may hold the key to why matter survived the Big Bang, allowing stars, planets, and life to exist. Scientists believe this forgotten neutrino reshaped the early universe and may have left detectable gravitational wave signals that
Scientists have discovered that trees can sense their own shape and straighten their trunks using specialized wood that acts like opposing muscles. This remarkable ability helps trees maintain their posture and could lead to stronger forests, better timber, and more resilient
Scientists have uncovered a hidden mechanism that allows high-cholesterol diets to undermine the body's natural cholesterol defenses, and blocking it dramatically lowered harmful LDL cholesterol in mice. Even more promising, an experimental drug targeting this pathway has
Among Kepler and TESS's many surprising exoplanet discoveries are the ultra-short-period (USP) planets. These planets move very quickly and complete an orbit in less than 24 hours. Ancient astronomers thought that Mercury was so fast—it goes around the sun every 88 days—that
What's that chirping sound coming through the detector? Did you feel something whiz past? Those are just some ways people react when they encounter microbats for the first time. Microbats are small, mostly nocturnal mammals that use ultrasonic sounds to navigate and hunt at
Researchers have discovered a gene for a tandem potassium channel in an algal virus. The finding supports the view that giant viruses may have contributed significantly to the evolution of complex proteins. The study is published in the journal Proceedings of the National
More people are turning to artificial intelligence (AI)-powered chatbots for companionship and to address loneliness. But can AI-generated empathy replace human connection?
Many have voiced concerns that artificial intelligence will take jobs away from humans. But assistant professor of chemistry Zhongyue (John) Yang, along with his former doctoral student Qianzhen Shao (now a postdoc at Stanford) and other team members, has created an AI tool
It may sound abstract, but distinctions between "native," "introduced" or "invasive" species can often be life or death. Species considered invasive in Australia—such as European rabbits and feral pigs—are often culled, while most native animals are generally left alone.
According to quantum electrodynamics, the theory describing interactions between light and electrically charged particles, a sufficiently strong electric field can, in principle, convert some of its energy into particles and their antimatter partners. A particle's antimatter
As quantum computers grow more ambitious, many researchers believe the best way forward is to build them in multiple interconnected parts. In these modular designs, separate quantum processors are linked so they can work together as one larger machine. For this to happen,
Around 2,400 years ago, at Łysa Góra in Poland, a group of people took a bronze helmet, crushed it, broke it into pieces and threw it into a pit with iron adzes and a scythe. Such helmets are sometimes found in lavish graves of the Celtic warrior elite, from Champagne, France,
A kerosene-based gel developed by Concordia researchers could make rocket and satellite fuels easier to store and control.
Scientists at Johns Hopkins have uncovered a crucial missing link between a common gut bacterium and colorectal cancer, solving a mystery that has puzzled researchers for nearly two decades. The bacterium, Bacteroides fragilis, produces a toxin that damages the colon’s
A remarkable 4,000-year-old defensive structure discovered in Morocco is rewriting what scientists thought they knew about ancient North African civilizations. The massive fortifications reveal unexpectedly sophisticated prehistoric societies and suggest that the region played
Among the ravenous carnivores and lumbering herbivores that roamed the Cretaceous landscape, another kind of dinosaur was evolving that started to eat something else: the plants that began to flower and produce fruit. The discovery by paleontologists from Stony Brook
Scientists have discovered a surprising mechanism that allows certain metals to resist cracking at temperatures as low as -253°C (-424°F), when similar materials typically become dangerously brittle. Instead of breaking, two experimental alloys reorganize their internal
A research team has designed and synthesized a molecular cage with an internal cavity by connecting two curved π-conjugated molecules face-to-face at three points.
