For nearly 300,000 years, early humans shaped stone tools with precision, even as they faced constant wildfires, severe droughts, and dramatic shifts in their environment. A new study published in Nature Communications reveals astonishing evidence of this long-lived technological tradition in Kenya’s Turkana Basin. At the Namorotukunan Site, an international team of researchers uncovered one…

How did early civilizations respond when their worlds fell apart? Archaeologists from the University of Copenhagen believe the 5,000-year-old site of Murayghat in Jordan may reveal some clues. Their extensive excavations suggest that this Early Bronze Age community developed powerful new traditions in the aftermath of cultural collapse. Murayghat rose to prominence after the decline…

Dark energy, the mysterious force thought to drive the universe’s accelerating expansion, remains one of the deepest puzzles in modern physics. For years, the leading explanation has been that this energy is constant — an unchanging property of empty space responsible for cosmic acceleration. But recent evidence has scientists rethinking that assumption. Last year, results…

As easily as the mind can drift off course, it also has the remarkable ability to refocus. Researchers at MIT’s Picower Institute for Learning and Memory have uncovered how that process may work. In a new animal study, they found that synchronized neural activity, appearing as a rotating wave across the brain, helps guide thought…

A collaboration between Brazilian and German researchers has led to a sunflower-based meat substitute that’s high in protein and minerals. The new ingredient, made from refined sunflower flour, delivers excellent nutritional value and a mild flavor. Tests showed strong texture and healthy fat content, suggesting great potential for use in the growing plant-based food sector….

Imagine a frog inside a box with an opening partway up one side. Whether it can escape depends on how much energy it has: if it can jump high enough, it could, in theory, reach the opening. But success requires more than just a high jump — it also needs to pass through that opening….

Far beneath the ocean’s surface, researchers have found bacteria that can digest plastic, using specialized enzymes that evolved alongside humanity’s synthetic debris. A large-scale global study by scientists at KAUST (King Abdullah University of Science and Technology) revealed that these marine microbes are widespread and genetically prepared to consume polyethylene terephthalate (PET) — the tough…
