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 […]
Genetic material has been analyzed from members of a large Swiss family, the majority of whom suffered from auto-somal dominant juvenile cataract. From the DNA, researchers at ETH Zurich and the University Zurich identified the chromosomal location and exact molecular defect in the coding region of the gene responsible for the type of childhood cataract. Until now, no […]
Scientists from Newcastle University, UK led by Professor Patrick Chinnery, have created an embryo with three separate parents. The team believe the technique could help to eradicate a whole class of hereditary diseases, including some forms of epilepsy and ensure women with genetic defects do not pass the diseases on to their children.
Ten severely deformed embryos, left […]
Over the past two years here at Genetics and Health, I’ve written almost 1,200 posts and received over 2,000 posts comments all on genetics, genes, the genome, and DNA. Having the opportunity to write about my lifelong passion is a dream come true. So that I can improve and grow as a genetics blogger, writer, […]
A Florida bill to require DNA testing of pregnant girls under the age of 14 has been voted down. The bill would have asked doctors, nurses, and other healthcare workers (including abortion providers) to collect DNA from the girl and her fetus for the purpose of identifying the father for prosecution. Sex with minors under […]
My vacation has thus far not included a spa visit, but if I ever do make it to one again in my lifetime, I might be tempted to find one that offers DNA testing. More in the New York Times:
It is possible to get many things at the Four Seasons Hotel in Westlake Village, […]
Knowing more about your risk of type 2 diabetes is just a keyboard click away at DNA Direct. Together with deCODE diagnostics, DNA Direct is now offering deCODE T2, a genetic test that examines the presence of the “T” allele of SNP rs7903146, located within the transcription factor 7-like 2 (TCF7L2) gene. Almost twice as […]
Yesterday, I joked around about setting my DNA sequence to music. It’s not as crazy as you might think. Dr. MA Clark has done just that with some well known DNA sequences. Here’s genetic music based on SRY, the male determining factor.
