Nanotechnology researchers are continually on the lookout for new building blocks to push innovation and discovery to scales much smaller than the tiniest speck of dust. At present DNA nanotechnology researchers are basically limited by what they can buy off the shelf.
In the Biodesign Institute at Arizona State University, researchers led […]
Osteoporosis

An extensive genome-wide search has been undertaken to find the genes linked to osteoporosis and fracture. Five regions of interest have been identified that appear to warrant further scientific investigation.
The Garvan Institute for Medical Research collaborated with the Icelandic genetics company, deCode, in a project that looked at 1500 women from Garvan’s Dubbo Osteoporosis […]
KQED Public Broadcasting in San Francisco recently did a radio story about the UC San Francisco Canine Behavioral Genetics Project run in collaboration with the University of Pennsylvania. The aims of the project are:
1. To explore the relationship between genes and behavior, both normal and abnormal, in domestic dogs.
2. To assess the amount and nature […]

Data from one of the first genome-wide association studies (GWAS), which focused on Parkinson’s diseases and was funded in part by The Michael J. Fox Foundation for Parkinson’s Research (MJFF), is now being made available to researchers through the National Human Genome Research Institute (NHGRI) and the National Center for Biotechnology […]

A team of researchers at the University of Alberta has discovered a gene that is able to block HIV, and in turn prevent the onset of AIDS. Stephen Barr, a molecular virologist in the Department of Medical Microbiology and Immunology, says his team has identified a gene called TRIM22 that can block […]
Further to my various articles on our ancestry, differences in gene expression levels between people of European versus African ancestry appear to affect how each group responds to certain drugs or fights off specific infections, report researchers from the University of Chicago Medical Center and the Expression Research Laboratory at Affymetrix Inc. of Santa Clara, CA.
The researchers […]
The Hebrew University of Jerusalem scientists and others have revealed for the first time the electronic structure of single DNA molecules. In their work, the researchers were able to decode the electronic structure of DNA and to understand how the electrons distribute into the various parts of the double helix, a result that has been […]
Papers published in Nature and Science this week support the previously held theory that humans originated in East Africa, migrating outward until they reached all parts of the globe. But the genetic work from these studies brings a new level of precision to human migration studies, with each group finding subtle and intriguing details that shed light on different aspects of […]
Molecular structure of Aspartame
I recently wrote an article on my first hand research experience on the potential carcinogenicity of Aspartame - the artificial sweetener used in thousands of everyday products, particularly diet products. It was titled “Aspartame is safe … really!”
One of www.geneticsandhealth.com readers author Carol Guilford sent me the following interesting link to a piece of […]
Our early human ancestors originated from a hot, humid climate where natural selection focused on dispersing heat. As humans migrated to colder climates there would have been evolutionary pressure to adapt to their new settings by boosting the processes that produce and retain heat.
Genes involved in energy metabolism are therefore likely to be central to heat and cold […]
