Applied Bioinformatics Course offered at the MDI Biological Lab in Maine, July 23-28
The Mt. Desert Island Biological Lab in ME is partnering with the Dartmouth SRP and Director Bruce Stanton to run a course on Applied Bioinformatics. The goal of the course is to provide hands-on training with major bioinformatics resources while developing a conceptual framework to foster successful application of the bioinformatic skillset to biological research.

Elevated Bladder Cancer Risk in New England Linked to Arsenic in Drinking Water from Private Wells
A new study from the National Cancer Institute shows that drinking water from private wells may have contributed to elevated risk of bladder cancer in New England. Dartmouth Superfund researcher, Dr. Margaret Karagas, participated in the study. National Cancer Institute press release; NH DES press release.
Drinking Water Forum in Maine
On April 24, a community forum on drinking water issues will be convened by the Environmental Health Strategy Center/Prevent Harm in Rockport, ME. A panel of speakers will discuss the problem of arsenic in well water from different perspectives.
Researcher Margaret Karagas Quoted in NY Times on FDA Proposed Limit for Arsenic in Rice Cereal
Bruce Stanton Presented at 2016 SOT Annual Meeting
Bruce Stanton, Ph.D., presented at the SOT (Society of Toxicology) 2016 Annual Meeting in March as part of a workshop entitled Moving beyond cancer: current state of the science of noncancer health effects of arsenic. His talk focused on arsenic and pulmonary infections.
US Supreme Court Rejects Attempt to Stay MATS
The US Supreme Court has rejected a petition by 20 states to temporarily halt enforcement by the EPA of regulations that limit heavy metal pollution from oil- and coal-fired power plants. Led by Michigan, the states had asked the Court to stay the Mercury Air Toxics Standard commonly referred to as MATS while the D.C. Circuit court considers its legality.

Tulane Professor Tests for Arsenic in Rural LA Drinking Water
Research conducted by Tulane University geochemistry professor Karen Johannesson has found the presence of arsenic in parts of rural LA to be at least 10 times higher than EPA standards of less than 10 parts per billion. While the amount is significantly less than what she and her colleagues found in the Bengal Basin of India , she says that it is alarming nonetheless, as arsenic is associated with an array of health issues. Dr. Johannesson's team's paper on arsenic in shallow groundwater from the Napoleonville, LA site recently was accepted for publication in the Journal of Hydrology: Regional Studies.
YouTube Video Highlights Student Dragonfly Work
The YouTube video "Outside Science (inside parks): Blue Skies and Dragonflies" highlights student citizen science research collecting dragonfly larvae. The larvae are indicators of pollution, and are used to study the amount of mercury present in the environment. Their research is similar to our SRP Dragonfly project and is part of the US-wide dragonfly research collaboration that researcher Celia Chen is involved with.
Investigators Find High Concentrations of Toxic Metals in Whales
Investigations led by the University of Aberdeen, in collaboration with the Scottish Marine Animal Stranding Scheme, have shown that a pod of beached whales had high concentrations of mercury and cadmium, including in their brains. The level of these toxic metals in the whales increased with their age. Scientists found mercury at levels high enough to cause severe neurological damage in humans and demonstrated for the first time that the toxic element cadmium can cross the blood-brain barrier in adults. See article in The Press and Journal.
Researcher Brian Jackson Quoted on Effects of Arsenic Levels in Rice Snacks
"If you are a person who is eating rice every day, and also snacking on rice products, then that five micrograms from rice crackers becomes significant. If once a month, not so much," Brian Jackson, a research associate professor and the director of Dartmouth's Trace Metal Analysis Core Facility, tells The Daily Meal in a story about arsenic levels in the snacks and whether they pose a risk to people.

Dr's Guerinot & Punshon's Award Winning Image Featured
Mary Lou Guerinot is featured in a Dartmouth news video discussing hers and Tracy Punshon's FAESB Bio-Art competition award winning image of zinc in an Arabidopsis plant. They also were featured in the NIEHS Director's Blog on January 21. Their entry will be displayed in the NIH Visitors Center.
Study on Lentils Can Counteract Arsenic Poisoning in Bangladesh
Researchers at the University of Calgary are studying whether Saskatchewan-grown lentils can counteract the effects of chronic arsenic poisoning from well water in Bangladesh. This problem affects up to 77 million people in that country and has been called "the worst case of mass poisoning in the world" by the World Health Organization (WHO). The study is described on the CBCNews web site.
FDA Withdraws Approval of Arsenic-based Nitarsone in Animal Feed
The U.S. Food and Drug Administration has withdrawn approval of the use of Nitarsone in animal feed as of December 31, 2015 as reported on the FDA website.
