Description
Archaeologists have pushed back the timeline for human settlement in Britain by 500 years, revealing just how dramatically small climate shifts shaped early human migration. A 250-million-year-old fossilized egg containing an embryo has finally settled a long-standing debate about early mammal relatives — and may explain how they outlasted one of Earth's deadliest mass extinctions. Researchers at UCLA have developed a single blood test capable of detecting multiple cancers and organ diseases simultaneously, potentially transforming how we screen for illness. A common industrial chemical hiding in groundwater has been linked to a staggering 500% increased risk of Parkinson's disease, prompting urgent calls for regulation. And a new study suggests the people you live with may be silently reshaping your gut microbiome in ways that affect everything from digestion to mental health.
