Astronomers are rethinking one of cosmology's biggest mysteries: dark energy. New findings show that evolving dark energy models, tied to ultra-light axion particles, may better fit the universe's expansion history than Einstein's constant model. The ...

Long ago, some saltwater fish adapted to freshwater -- and in doing so, developed an extraordinary sense of hearing rivaling our own. By examining a 67-million-year-old fossil, researchers from UC Berkeley discovered that these "otophysan" fish didn ...

Researchers at McMaster University have discovered that the eyes may offer a powerful, non-invasive way to assess heart health and biological aging. By analyzing retinal scans alongside genetic and blood data from over 74,000 participants, they found ...

Researchers found that embodying a digital, childlike version of one's own face helps unlock vivid childhood memories. This illusion strengthens the connection between bodily self-perception and autobiographical recall. The findings suggest that ...

Okayama scientists have crafted a new wine grape, Muscat Shiragai, merging the wild Shiraga and Muscat of Alexandria. The variety is part of a larger collaboration between academia, industry, and local government to boost regional identity through .. ...

UC San Diego researchers combined artificial intelligence with molecular biology to unravel how immune cells in the gut decide between inflammation and healing, a process gone awry in Crohn's disease. They discovered that the NOD2 gene's interaction ...

Physicists have uncovered how direct atom-atom interactions can amplify superradiance, the collective burst of light from atoms working in sync. By incorporating quantum entanglement into their models, they reveal that these interactions can enhance ...

Boston researchers linked nighttime light exposure to greater stress-related brain activity and inflamed arteries, signaling a higher risk of heart disease. The study suggests that artificial light at night disrupts normal stress responses, leading . ...

In the Gulf of California, a pod of orcas known as Moctezuma's pod has developed a chillingly precise technique for hunting young great white sharks -- flipping them upside down to paralyze and extract their nutrient-rich livers. The behavior, filmed ...

Researchers at UC San Diego have figured out how to get bacteria to produce xanthommatin, the pigment that lets octopuses and squids camouflage. By linking the pigment's production to bacterial survival, they created a self-sustaining system that ...
