🔬 A 250M-Year-Old Egg Just Rewrote Prehistory — Plus The Blood Test That Could Detect Cancer Before Symptoms Appear

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.Subscribe to Peer Review'd Newsletter: https://peerreviewd.com/Love Science?
