Gas Leaks From Faulty Wells Linked to Contamination in Some Groundwater

A study has pinpointed the likely source of most natural gas contamination in drinking-water wells associated with hydraulic fracturing, and it’s not the source many people may have feared.

Acute Photo-Induced Toxicity and Toxicokinetics of Single Compounds and Mixtures of Polycyclic Aromatic Hydrocarbons in Zebrafish

In a recent publication, toxicity in zebrafish larvae was investigated from exposure to mixtures and multiple stressors. Mixtures included exposure to all combinations of four PAHs, with the additional stressor of ultraviolet light leading to phototoxic effects. The results indicated all PAHs were phototoxic and the mixtures mechanism of toxicity was additive. Data were compiled and a predictive toxicity model was developed.

Smoke This! Public Health Impacts of E-Cigarettes

Despite the fact that traditional cigarette consumption has been on the decline in the United States since the mid-1970s, the use of electronic cigarettes, or “e-cigarettes,” among adults and teenagers is becoming more and more prevalent. These devices are regularly marketed as a safe alternative to smoking conventional cigarettes, and are promoted as smoking cessation aids, similar to nicotine patches and nicotine gum. However, e-cigarettes are becoming increasingly scrutinized by health experts and regulatory agencies and there are an increasing number of questions surrounding these safety claims, particularly in regard to exposure among teenagers and young children. This article explains the known and anticipated risks of e-cigarette use, as well as the potential for accidental ingestion of liquid nicotine by small children.

New Report: Illegal Land Clearing for Commercial Agriculture Responsible for Half of Tropical Deforestation

A comprehensive new analysis released today says that nearly half (49%) of all recent tropical deforestation is the result of illegal clearing for commercial agriculture. The study also finds that the majority of this illegal destruction was driven by overseas demand for agricultural commodities including palm oil, beef, soy, and wood products. In addition to devastating impacts on forest-dependent people and biodiversity, the illegal conversion of tropical forests for commercial agriculture is estimated to produce 1.47 gigatonnes of carbon each year—equivalent to 25% of the EU’s annual fossil fuel-based emissions.

Scientists Map the ‘Editing Marks’ on Fly, Worm, Human Genomes

In the August 28 issue of the journal Nature a multi-institution research network called modENCODE (the Model Organism ENCylopedia Of DNA Elements) published three major papers that map and compare the genomes and epigenomes of humans and two model organisms, the fly, D. melanogaster, and the worm, C. elegans, in unprecedented detail. The fly and worm could serve as model organisms for screening drugs and micronutrients that might alter the epigenome, which is implicated in many diseases.

Black carbon pollutants from wood smoke are known to trap heat near the earth’s surface and warm the climate. A new study led by McGill Professor Jill Baumgartner suggests that black carbon may also increase women’s risk of cardiovascular disease.

Reduced Testosterone Tied to Endocrine-Disrupting Chemical Exposure

Men, women and children exposed to high levels of phthalates - endocrine-disrupting chemicals found in plastics and some personal care products – tended to have reduced levels of testosterone in their blood compared to those with lower chemical exposure, according to a new study published in the Endocrine Society’s Journal of Clinical Endocrinology & Metabolism (JCEM).
