A new study uncovers eleven gene variants associated with three blood lipids measured to determine cardiovascular disease risk: low-density lipoprotein (LDL) cholesterol, high-density lipoprotein (HDL) and triglycerides. The discovery opens up new opportunities for nutrigenomics researchers looking for links between diet and genetics that will optimize health and lower chronic disease risk.

"Practically all genes related to lipid levels in the bloodstream respond to changes in the diet," says Jose M

How We Learn from Our Mistakes

Eric wu submitted, created time 1 year 1 month (www.time.com)

Everyone can learn from their mistakes — but some people have genes that may make it harder. That's the message from German researchers, writing in tomorrow's issue of the journal Science, who have shown how a common gene variant affects some people's ability to respond to, and learn from, the negative repercussions of their actions.

"Clock gene anomalies have been suggested as causative factors in autism. Researchers screened eleven clock/clock-related genes in a predominantly high-functioning Autism Genetic Resource Exchange sample of strictly diagnosed autistic disorder progeny and their parents (110 trios) for association of clock gene variants with autistic disorder. They found significant association (P<0.05) for two single-nucleotide polymorphisms in per1 and two in npas2
