A Genetic Predisposition To Alcohol Dependence May Be Indicated By Sensitivity To Alcohol Odors
Single nucleotide polymorphisms (SNPs) are DNA sequence variations that occur when a single nucleotide in the genome sequence is altered. Prior research suggested an association between SNPs in a gene that encodes aspects of the brain's gamma-amino butyric acid (GABA)-A receptors (the GABRA2 gene) and alcohol dependence...

Chromosomal Rearrangement, Gene Copy Number Methods Featured In Cold Spring Harbor Protocols
A cell devotes a significant amount of effort to maintaining the stability of its genome, preventing the sorts of chromosomal rearrangements characteristic of many cancers. Assays that measure the rate of gross chromosomal rearrangements (GCRs) are needed in order to understand the individual genes and the different pathways that suppress genomic instability...

Novel Nanotechnology Collaboration Leads To Breakthrough In Cancer Research
One of the most difficult aspects of working at the nanoscale is actually seeing the object being worked on. Biological structures like viruses, which are smaller than the wavelength of light, are invisible to standard optical microscopes and difficult to capture in their native form with other imaging techniques...

Capacity For Exercise Can Be Inherited, Suggesting That Pharmaceutical Drugs Can Be Used To Alter Activity Levels In Humans
Biologists at the University of California, Riverside have found that voluntary activity, such as daily exercise, is a highly heritable trait that can be passed down genetically to successive generations. Working on mice in the lab, they found that activity level can be enhanced with "selective breeding"- the process of breeding plants and animals for particular genetic traits...

Group Health Study Reveals That People Want To Be Asked Before Sharing Genetic Data
People want to be informed and asked for consent before deciding whether to let researchers share their genetic information in a federal database. This is according to a team of investigators at Group Health Research Institute and the University of Washington (UW). The team's report, called "Glad You Asked," is in the September 2010 Journal of Empirical Research on Human Research Ethics...
