UCLA scientists mined millions of electronic health records and uncovered four distinct “roadways” that funnel people toward Alzheimer’s—ranging from mental-health struggles to vascular troubles. Following these breadcrumb trails proved far better at predicting who will develop dementia than single risk factors. The findings hint that spotting—and halting—specific sequences early could rewrite how we prevent the …

Feral water buffalo now roam Hong Kong s South Lantau marshes, and a 657-person survey shows they ignite nostalgia, wonder, and worry in equal measure. Many residents embrace them as living links to a fading rural past and potential conservation icons, yet others fear road blockages, safety hazards, and ecosystem impacts. Attitudes skew more positive …

A surprising discovery from a tiny grain of asteroid Ryugu has rocked scientists’ understanding of how our Solar System evolved. Researchers found djerfisherite—a mineral typically born in scorching, chemically reduced conditions and never before seen in Ryugu-like meteorites—inside a sample returned by Japan’s Hayabusa2 mission. Its presence suggests either Ryugu once experienced unexpectedly high temperatures …

Scientists have uncovered a surprising new way that urea—an essential building block for life—could have formed on the early Earth. Instead of requiring high temperatures or complex catalysts, this process occurs naturally on the surface of tiny water droplets like those in sea spray or fog. At this boundary between air and water, a unique …

A newly discovered radio halo, 10 billion light-years away, reveals that galaxy clusters in the early universe were already steeped in high-energy particles. The finding hints at ancient black hole activity or cosmic particle collisions fueling this energy. ​A newly discovered radio halo, 10 billion light-years away, reveals that galaxy clusters in the early universe …

USC researchers have found a promising new brain scan marker that could better detect Alzheimer’s risk — but only for some. The tau-based benchmark works in Hispanic and White populations when paired with another Alzheimer’s protein, amyloid, but falls short for Black participants, revealing critical gaps in current diagnostics. ​USC researchers have found a promising …

Deleting a gene called PTEN in certain brain cells disrupts the brain’s fear circuitry and triggers anxiety-like behavior in mice — key traits seen in autism. Researchers mapped how this genetic tweak throws off the brain’s delicate balance of excitation and inhibition in the amygdala, offering deep insights into how one gene can drive specific …

India’s complex ancestry—intertwined with Iranian farmers, Steppe herders, and local hunter-gatherers—has now been decoded through genomic data from 2,762 people. The study uncovers surprising levels of Neanderthal and Denisovan DNA, and how ancient migrations and community traditions have shaped today’s genetic diversity and disease risks. ​India’s complex ancestry—intertwined with Iranian farmers, Steppe herders, and local …

Footprints found in the ancient lakebeds of White Sands may prove that humans lived in North America 23,000 years ago — much earlier than previously believed. A new study using radiocarbon-dated mud bolsters earlier findings, making it the third line of evidence pointing to this revised timeline. ​Footprints found in the ancient lakebeds of White …
