With more than $1.5 million from the National Institutes of Health over the next four years, Brown University epidemiologist Joseph Braun will study how exposure to three common chemicals during pregnancy and childhood affects brain development and the thyroid.
PROVIDENCE, R.I. [Brown University] — Exposure to the endocrine disrupting chemicals bisphenol A, triclosan and phthalates is ubiquitous in the United States, raising concerns that they may affect health. With a new four-year, $1.5 million grant from the National Institutes of Health, Brown University epidemiologist Joseph Braun will try to close a gap in research: the effect of these exposures on the brain and thyroid during pregnancy and childhood.
This toxic algal bloom, imaged over Lake Erie in 2011, resulted from the release of excess nitrogen and other nutrients into the environment. The culprit? Fertilizers and other industrial byproducts. Photo Credit: NASA Earth ObservatoryCarbon compounds are arguably the most infamous of all the greenhouse gases, but they are not the only chemical offenders deserving of concern. In fact, nitrogen is capable of causing severe damage to the environment as well. This simple element, harmless when safely bound in pairs in Earth’s atmosphere, becomes extremely volatile when generated by human activities. When combined with other elements such as hydrogen and oxygen, so-called reactive nitrogen compounds wreak havoc on the environment by way of soil acidification, smog production, and the release of excess chemical nutrients into the environment, a process known as eutrophication.
Although reactive nitrogen is also produced in nature, human methods of mass food production have outstripped even the most prolific nitrogen-producing ecosystems. Since the 1970s, we humans have driven greater numbers of our species up the food chain by consuming more animal protein and crops such as legumes than ever before, all the while releasing higher and higher levels of reactive nitrogen into the environment around us.
Nitrogen, in this sense, is both a boon and a curse.
Therefore, the question driving scientists is one of balance: How can we humans be responsible about our nitrogen emissions while simultaneously advancing the world’s societies?
The latest Impact Factor rankings are in! For the first time, the AMS journal "Weather, Climate and Society" has made the Top 40 most-cited Meteorology and Atmospheric Science publications. Institute Director Amanda Lynch became Chief Editor of the journal in 2013, at which time WCAS ranked #63 out of 76 publications.
Three cheers for Amanda and the rest of the WCAS editorial staff and contributors! The most recent issue of the journal can be found here.

This August, the Ecological Society of America (ESA) will host its 100th Annual Meeting in Baltimore, Maryland. The meeting will focus primarily on the ecology of the nearby Chesapeake Bay watershed. IBES postdoctoral fellow Becca Ryals and graduate students Amy Teller and Maya Almaraz will present their research on the effects of nitrogen-rich biochar and fertilizers on local ecosystems. Ryals, Teller, and Almaraz are featured in the ESA press release about the conference, which is excerpted below.
