The effect of foods on gene expression is a fairly new area of science termed nutrigenomics. Many people are highly interested in how they may protect or prevent disease or conditions by applying diets appropriate to ones genetic make-up. Although early in its stages nutrigenomics has identified some very interesting findings. One interesting find was a clinical trial linking olive oils to the anti-inflammatory response
Extra virgin olive oil has been shown to reduce the expression of 98 genes involved in the inflammatory response by researchers from the University of Cordoba (Camargo A et al. 2010). Polyphenols are the primary beneficial More >
Science experiments are not usually meant to be eaten; even water and gum are strictly banned from laboratories. But as scientists continue to perfect techniques for genetic manipulation, the products of their experiments are increasingly making appearances in super markets and on dinner tables.
While the genetic modification of plants for human consumption is common in the United States (think corn and soybeans), genetically modified (GM) animals have yet to be approved. But now, a Massachusetts-based company, AquaBounty, is petitioning the FDA to sell genetically modified Atlantic Salmon to consumers.
Thanks to some genetic mix and match, the salmon, dubbed AquAdvantage, reach More >
Most everyone has had the pleasure of being stuck in close quarters with a person who feels compelled to speak as loudly as possible into their cell phone. Annoying cell phone conversations are such a popular pet-peeve that it’s not uncommon to have “quiet cars” on trains, or signs banning cell phones in certain public locations. It’s quite likely that you have been on a train or bus where two people were talking to each other, and yet you didn’t have the same reaction you had to a person chatting into his phone. Excepting libraries, people chatting with each other More >
Recent news has again brought eugenics into present day politics. The GOP has decided not to endorse the candidacy in New York of Jim Russell for congress due his views published in a paper about 10 years ago. All funding, volunteers, and any other resources are being withdrawn. Russell’s comments about interracial marriage are drawing the most attention:
“In the midst of this onslaught against our youth, parents need to be reminded that they have a natural obligation, as essential as providing food and shelter, to instill in their children an acceptance of appropriate ethnic boundaries for socialization and for marriage.”

Each day your body works to defend you against invaders. Harmful bacteria, viruses, and fungi can enter your system and cause diseases. In addition to relying on your immune system, it is helpful to avoid contact with germs by thoroughly washing your hands and keeping your environment clean.
How is it possible that some organisms have the ability to survive in some of the dirtiest places on earth? What survival mechanisms do they have that differ from ours?
Scientists ground up the brains and other nerve tissues from two species of insects, the American cockroach and the desert locust. Material extracted from More >
In an earlier post I blogged about the nature of dreams including phases of sleep and why we dream. In the blog I had mentioned a sleep disorder known as REM sleep behavior disorder (or RBD). It’s a mysterious sleep disturbance where the normal atonia (muscle paralysis) during sleep malfunctions, and the dreamer is left to act out their dreams. Those with this disorder (predominantly male) tend to have dreams that are increasingly violent and involve fighting off an attacker. In their sleep, these people act out every punch, kick, twist and scream with their sleeping bodies, often times injuring More >
