Geochronologist Richard Ku's analysis of Peking Man fossils reveals they date back to at least 400,000 years ago, significantly older than previous estimates. This finding sheds new light on human evolution and challenges current understanding of the species' origins.
Researchers at Stanford Human Genome Center developed a powerful new computer program called Mapper to map thousands of genetic markers simultaneously. This allows for high-resolution maps with better local area resolution and rapid rebuilding process.
Stanford researchers are working on a new PSA test that can distinguish between cancerous and non-cancerous prostate enlargement. By analyzing the PSA protein extracted from enlarged prostates, they aim to eliminate unnecessary biopsies. The team's approach has shown promising results, reducing false positives by up to 86%.
