The January issue of Environmental Health Perspectives (EHP)(http://ehp.niehs.nih.gov/january-2010/) is sure to catch the attention of sleep-challenged readers with its cover stories on light exposure, circadian rhythm, and sleep — "What's in a Color? The Unique Human Health Effects of Blue Light" and "Lose Sleep, Gain Weight: Another Piece of the Obesity Puzzle."
The stories examine some of the human health effects unique to the influence of blue light on regulation of the body's inner circadian clock, as well as the connection between chronic lack of restorative sleep and a host of metabolism-related health problems, including obesity and metabolic syndrome.
Also appearing in EHP this month are several new studies:
- Aerosolized Nanomaterials in Environmental Studies — exploring the potential for laboratory workers to be exposed to airborne engineered carbonaceous nanomaterials during routine material handling
- Summer Heat and Mortality: How Hot Is Too Hot? — examining 10 years of all-cause mortality data (1997-2006) for New York City residents to identify the most appropriate criteria for triggering health alerts
- Concentrations of the Active Metabolite of Tamiflu in Wastewater Samples — investigating levels of the flu-medication metabolite in sewage treatment plant wastewater and describing a sewage treatment method that may reduce environmental contamination and help prevent the emergence of drug-resistant influenza strains
- Childhood Brain Tumors and Insecticide-Metabolism Genes — analyzing population-based case-control data to assess whether childhood brain tumors are associated with select functional genetic polymorphisms
