The team now hypothesizes that under broad-spectrum daylight conditions, these genes would be subsequently deactivated by wavelengths from a different part of the spectrum — but these additional wavelengths may be absent in fluorescent lighting. The skin and brain of the three animals, as well as the liver of both fish models all exhibit, increased inflammation and immune responses; however, the mouse liver suppressed this reaction. Overall, the conserved nature of the genetic responses observed, among fishes and a mammal, suggest the presence of light responsive genetic circuitry that is deeply embedded in the vertebrate genome.

Neuroscientist Sara Lazar found that people who practiced meditation had more gray matter in the part of the brain linked to decision-making and working memory: the frontal cortex. While most people see their cortexes shrink as they age, 50-year-old meditators in the study had the same amount of gray matter as those half their age. Participants in the study averaged about 27 minutes of the habit a day, but other studies suggest that you can see significant positive changes in just 15 minutes a day.

Abstract Autoimmune diseases result from an interplay of genetic predisposition and factorswhich stimulate the onset of disease. Mercury (Hg), a well-established toxicant, is an environmental factor reported to be linked with autoimmunity. Hg exists in several chemical forms and is encountered by humans in dental amalgams, certain vaccines, occupational exposure, atmospheric pollution and seafood. Several studies have investigated the effect of the various forms of Hg, including elemental (Hg0), inorganic (iHg) and organic mercury (oHg) and their association with autoimmunity. In vitro studies using peripheral blood mononuclear cells (PBMC) from healthy participants have shown that methylmercury (MeHg) causes cell deathat lower concentrations than iHg albeit exposure to iHg results in a more enhanced pro-inflammatory profile in comparison to MeHg. In vivo researchRead More →

“What we need to ask is, Why has BMI gone up?” he says. “Decreased physical activity and a more calorically dense diet are probably part of the puzzle. But I think another critical piece is our ubiquitous environmental exposure to endocrine-disrupting chemicals,” or EDCs. This class of chemicals (including phthalates, bisphenol A and others) is used in many consumer products (shower curtains, plastic bottles, couch cushions) and has been shown to mimic estrogen and other naturally occurring hormones in the human body. Biro theorizes that some of these chemicals may promote weight gain or contribute to early puberty by influencing how cells and the bodyRead More →

The revolution is being led by Robert Oliver, a 58-year-old New Zealander who grew up in Fiji and Samoa, where his father was a social worker. “When you look at pictures from the 1970s and early ’80s, they were just wonderfully fit, healthy people,” says Oliver, who is host and executive producer of the program. “The diet was carb-heavy, fish-heavy, veg-heavy. But if you take out the greens and put in processed food and have a sweet drink, then you have a sugar bomb, because the carbs convert to sugar.” Source: Pacific Island Food Revolution: the reality TV show tackling the region’s health crisis RecommendRead More →
