Neanderthal Genetic Bottleneck 110,000 Years Ago May Explain Their Decline
A study suggests that Neanderthals experienced a population bottleneck 110,000 years ago, drastically reducing their genetic diversity. CT scans of their inner ear bones revealed a sharp decline in variation, indicating a drop in population size. This event may have made Neanderthals more vulnerable to environmental and competitive pressures, contr...

Genetic Risk Factor For Erectile Dysfunction Identified
In a first, researchers have found a specific place in the human genome that raises a person's risk of erectile dysfunction.Researchers from the US-based Kaiser Permanente have found variations in genetic locus -- near the SIM1 gene -- were associated with 26 per cent increased risk of erectile dysfunction.
