Scientists discover genius gene

COKE STROKE:

Using drugs such as cocaine can increase the risk of torn arteries and strokes, researchers say. Two women suffered severe strokes and a major tear in the neck artery after taking the drug methamphetamine, which is toxic to large arteries. 'Since cocaine has similar effects, it is therefore likely that the tears in the arteries may be due to a drug class effect rather than a specific drug such as methamphetamine,' said Wengui Yu of California University.

GENIUS GENE:

A gene variation that helps people live into their 90s and beyond has also been found to aid memory and learning in the elderly. It alters the size of cholesterol particles making them less likely to cause strokes. People aged 95 or older who had the gene variant were twice as likely to have good brain function, researchers at Albert Einstein College of Medicine in New York discovered.

HOT LARVAE:

The warming of oceans could be disastrous for many species of fish – including cod and herring – that reproduce through larvae drifting along on ocean currents.

Larvae from the same species travel far less in warmer waters than in colder water, researcher Mary O'Connor has found.

This could lead to in-breeding and lower survival rates, suggests Ms O'Connor, a graduate marine ecology student at the University of North Carolina.
