Dark matter may be invisible, but scientists are getting closer to understanding whether it follows the same rules as everything we can see. By comparing how galaxies move through cosmic gravity wells to the depth of those wells, researchers found .. ...

Chimps may revise their beliefs in surprisingly human-like ways. Experiments showed they switched choices when presented with stronger clues, demonstrating flexible reasoning. Computational modeling confirmed these decisions weren't just instinct. .. ...

Aalto University researchers have developed a method to execute AI tensor operations using just one pass of light. By encoding data directly into light waves, they enable calculations to occur naturally and simultaneously. The approach works ...

Researchers have sequenced the oldest RNA ever recovered, taken from a woolly mammoth frozen for nearly 40,000 years. The RNA reveals which genes were active in its tissues, offering a rare glimpse into its biology and final moments. Surprisingly, .. ...

Scientists discovered that a week of full submergence is enough to kill most rice plants, making flooding a far greater threat than previously understood. Intensifying extreme rainfall events may amplify these losses unless vulnerable regions adopt . ...

Scientists found that people who use both cannabis and tobacco show a distinct brain pattern tied to mood and stress regulation. Their scans revealed higher levels of an enzyme that reduces a natural feel-good molecule in the brain. This imbalance .. ...

Researchers found that tau proteins don't jump straight into forming Alzheimer's-associated fibrils--first they assemble into soft, reversible clusters. When the clusters were dissolved, fibril growth was almost entirely suppressed. This reveals a .. ...

A new floating droplet electricity generator is redefining how rain can be harvested as a clean power source by using water itself as both structural support and an electrode. This nature-integrated design dramatically reduces weight and cost ...

Scientists identified a small molecule that interrupts a harmful protein pair linked to diabetic inflammation and tissue damage. The compound helped wounds heal faster and reduced organ stress in both Type 1 and Type 2 diabetes models. Unlike typical ...

Researchers digitally mapped ancient Chinese tombs and discovered that their distribution mirrors shifts in political stability, population movements, and natural geography. Peaceful, prosperous eras produced more elaborate and numerous burial sites, ...
