Certain properties of environmental contaminates increase fetus vulnerability and exposure
Fetuses more vulnerable to some environmental contaminants penetrating into cord blood. Medical Xpress. June 26, 2015. A new research featured in the Environmental Science and Technology published by the American Chemical Society suggests that the fetus is more vulnerable to some pollutants with certain properties because they penetrate further into the feto-maternal system.
The Great Barrier Reef is in peril: Federal and Queensland governments must get serious
Development and the Reef: the rules have been lax for too long. Bob Pressey, Alana Grech, Jon C. Day, and Marcus Sheaves, The Conversation. May 28, 2015. Through coastal development, people have changed the Reef's coastal zone dramatically, and the direct result is the decline of the Reef's ecosystems. No single development has tipped the balance, but a litany of poor choices has resulted in a tyranny of small decisions, with a large cumulative impact.

B.C. under pressure to better evaluate and monitor natural resource development
Auditor general says B.C. doing better job at monitoring major natural-resource projects. Cam Fortems, Kamloops. May 30, 2015.
B.C.’s environmental assessment office is doing a better job at monitoring major natural-resource projects such as mines and power generation, B.C.’s auditor general, Carol Bellringer, has reported in a follow-up to a damning 2011 audit that found major gaps. In another report released this past week, Bellringer said government does not adequately consider what are termed “cumulative effects” of natural-resource development. She gave the example of a logging operation, which leads to mining, then cattle grazing and, finally, water draw for mining and agriculture.
Antibiotic use at early ages linked to diseases in adulthood
Infant antibiotic use linked to adult diseases. Pajau Vangay, Tonya Ward, Jeffrey S. Gerber, et al. Cell Host and Microbe, 17 (5). May 13, 2015. A new study led by researchers at the University of Minnesota has found a three-way link among antibiotic use in infants, changes in the gut bacteria, and disease later in life. The imbalances in gut microbes, called dysbiosis, have been tied to infectious diseases, allergies and other autoimmune disorders, and even obesity, later in life. Medical Xpress.
Social sciences central in understanding environmental health and justice
Social Science Collaboration with Environmental Health. Elizabeth Hoover, Mia Renauld, Michael R. Edelstein, and Phil Brown. Environmental Health Perspectives. May 12, 2015. Social science-environmental health team science has altered the way scientists traditionally explore exposure by pressing for cumulative exposure approaches and providing research data for policy applications.
