Scientists discovered the genetics from place to place within same tumor can be vastly different, making customization of cancer treatment hard

By David Cyranoski of Nature magazine Two of the largest studies yet carried out on the genetics of schizophrenia in Chinese populations have turned up three genetic loci, or chromosomal regions, previously not known to be related to the disease.

By David Cyranoski of Nature magazine Two of the largest studies yet carried out on the genetics of schizophrenia in Chinese populations have turned up three genetic loci, or chromosomal regions, previously not known to be related to the disease. These genome-wide association studies (GWAS), done independently and published in Nature Genetics on October 30, also begin to redress a geographical imbalance: until now, GWAS have focused mainly on Western populations.

Seattle Genetics' Adcetris is first drug approved for Hodgkin's lymphoma since 1977

By David Cyranoski of Nature magazine The largest-ever study of the genetics of depression is set to go ahead in China, after a major survey found that the condition largely has the same triggers and symptoms there as in the West -- albeit with a few startling exceptions. Previous studies on twins in Sweden have shown that genetics explains about 40% of a woman's risk of depression, and about 30% of a man's. [More]

A new study using genes from the DNA-testing service made new discoveries about Parkinson's. Now the company is poised to continue groundbreaking genetic research, at a pace much faster than traditional research. Google-backed genotyping service 23andMe is a novelty for many people: spit in a tube, send it to the company, pay $99 and find out what diseases you're genetically prone to and whether you have any long-lost relatives who also use the service.

By Marian Turner of Nature magazine When a research team started analyzing the genetics of micro-organisms from their university pond, they might have expected to find a couple of new species. [More]

Bacteria and archaea--collectively known as prokaryotes--live pretty much everywhere, dividing happily in places from stomach acid to deep-sea vents. They can thrive in so many different places because their genomes are incredibly flexible: they can alter, lose and duplicate genes almost at will
