The Taj Mahal’s iconic marble dome and soaring minarets require regular cleaning to maintain their dazzling appearance, and scientists now know why. Researchers from the United States and India are pointing the finger at airborne carbon particles and dust for giving the gleaming white landmark a brownish cast.
<p>Microbes of interest to clinicians and environmental scientists rarely exist in isolation. Organisms essential to breaking down pollutants or causing illness live in complex communities, and separating one microbe from hundreds of companion species can be challenging for researchers seeking to understand environmental issues or disease processes. A new National Science Foundation-supported project will provide computational tools designed to help identify and characterize the gene diversity of the residents of these microbial communities.</p>
If first-year Georgia Tech student Grace Brosofsky has her way, all of the landscaping across the Tech campus will be maintained without using any chemical herbicides in the coming years. And the whole idea grew out of a conflict between her parents over how to best keep their north Georgia lawn weed-free.
A paper outlining a new approach to teaching about sustainability and infrastructure co-authored by Armistead Russell appears in the just-published fall issue of The Bridge, the signature publication of the National Academy of Engineering. The paper covers the development, implementation and assessment of a new summer course they have delivered over the last two years.
The Water Environment Federation has recognized Professor John Koon’s contributions to water quality with a lifetime achievement award. Koon accepted the award at the federation’s Technical Exhibition and Conference (WEFTEC) this week in New Orleans.
School of Civil and Environmental Engineering professors Armistead Russell and Michael Bergin are part of a research group that has just won funding from the National Science Foundation to purchase a state-of-the-art, high-resolution mass spectrometer.
With more than 10 million service points, India’s rural drinking water system provides a real monitoring headache for public health officials. To help address the challenge, a three-continent research consortium is evaluating a novel environmental crowdsourcing technique that relies on 53-cent test kits and the nation’s ubiquitous mobile phone service.
Kostas Konstantinidis has won National Science Foundation funding to study the impact of ocean acidification on micro-organisms. The award is part of a round of grants focused on the affects of lower pH on the world's seas. Researchers will also study the ability of coral reefs to adapt and create new, compact ocean instruments.
