Her group have now analysed both the variability in the DNA surrounding the APOB gene and the low-density lipoprotein cholesterol levels in over 400 healthy volunteers, between the ages of 20 and 102. The aim was to see if there was any link between the two factors. Their results show that people ...Plant, bird and butterfly species dwindling in the United Kingdom, researchers report

Their results showed that the effects of nitrogen deposition could account for more than half of the variation in plant species richness.

What's more, with more survivors, genetic variability becomes less of an issue.
