Navigenics - the whole interview

G&H’s INTERVIEW WITH NAVIGENICS
Navigenics approached Genetics and Health for an interview. With so much written about similar genomics companies such as 23andme, Knome, deCODE genetics, I was intrigued to learn more about this company.  In particular, Navigenics appears to be the only company within this industry genre who provides a comprehensive wellness model – a […]

Genetic basis for painful peripheral artery disease

Peripheral artery disease image showing ‘furring up’ of arteries 
Peripheral vascular disease (PVD) can affect the arteries, the veins or the lymph vessels. The most common and important type of PVD is peripheral artery disease, which affects about 8 million Americans.  It becomes more common as a person gets older, and by age 65, about 12 to 20 % of […]

Flu virus has ‘coat’ which melts in the summer and makes it less virulent

(Photo credit: Flu viruses among cilia - National Geographic magazine http://www.nationalgeographic.com/)
US scientists have discovered a possible reason why the flu virus is seasonal and tends to infect people mostly in the winter. It has a jacket that melts in the summer causing the virus to die off, and stays hard in the winter, until it […]

‘Out of Africa’ - 3 studies trace human global migration

 
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 […]

More on personal genomics services

Family Tree DNA advises it is now offering DNA Traits a personal genomics service that specializes in DNA testing for specific diseases. This company offers individual tests, group tests, and even a membership plan, all for relatively cheap prices compared to the other companies offering genome-wide SNP scans. The difference between them and their competitors, they […]

Genetic adaptations to surviving a cold climate linked to diabetes, obesity and heart disease

 
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 […]
