Combined research efforts by scientists involved in the Gulf of Maine Toxicity (GOMTOX) project, funded by NOAA's Ecology and Oceanography of Harmful Algal Blooms (ECOHAB) program, and administered by the National Centers for Coastal Ocean Science (NCCOS), have led to enhanced understanding of toxic algal blooms on Georges Bank. This new information, coupled with an at-sea and dockside testing protocol developed through collaboration between GOMTOX and U.S.

Researchers have been able to reconstruct the genome sequence of an outbreak strain of Shiga-toxigenic Escherichia coli (STEC), which caused over 50 deaths in Germany, using an approach known as metagenomics which bypasses the need for growing bacteria in the lab.
An international team coordinated by Mark Pallen, Professor of Microbial Genomics at Warwick Medical School, was able to reconstruct the genome sequence through the direct sequencing of DNA extracted from microbiologically complex samples.
NEW ORLEANS, April 10, 2013 — An advance in micromotor technology akin to the invention of cars that fuel themselves from the pavement or air, rather than gasoline or batteries, is opening the door to broad new medical and industrial uses for these tiny devices, scientists said here today. Their update on development of the motors — so small that thousands would fit inside this "o" — was part of the 245th National Meeting & Exposition of the American Chemical Society, the world's largest scientific society, being held here this week.
NEW ORLEANS, April 10, 2013 — Scientists today answered a question that worries millions of owners and potential owners of electric and hybrid vehicles using lithium-ion batteries: How long before the battery pack dies, leaving a sticker-shock bill for a fresh pack or a car ready for the junk heap? Their answer, presented here at the 245th National Meeting & Exposition of the American Chemical Society (ACS), being held here this week, may surprise skeptics.
Researchers have been able to reconstruct the genome sequence of an outbreak strain of Shiga-toxigenic Escherichia coli (STEC) using metagenomics (the direct sequencing of DNA extracted from microbiologically complex samples), according to a study in the April 10 issue of JAMA, a Genomics theme issue. The findings highlight the potential of this approach to identify and characterize bacterial pathogens directly from clinical specimens without laboratory culture.
ANN ARBOR—In a development that could make the advanced form of secure communications known as quantum cryptography more practical, University of Michigan researchers have demonstrated a simpler, more efficient single-photon emitter that can be made using traditional semiconductor processing techniques.
As demand for computing and communication capacity surges, the global communication infrastructure struggles to keep pace, since the light signals transmitted through fiber-optic lines must still be processed electronically, creating a bottleneck in telecommunications networks.
Washington, D.C.— A team of researchers has made a major breakthrough in measuring the structure of nanomaterials under extremely high pressures. For the first time, they developed a way to get around the severe distortions of high-energy X-ray beams that are used to image the structure of a gold nanocrystal. The technique, described in April 9, 2013, issue of Nature Communications, could lead to advancements of new nanomaterials created under high pressures and a greater understanding of what is happening in planetary interiors.
New research from the University of Cincinnati shows how some things you do to make your lawn green might not be conducive to "going green."
Amy Townsend-Small, a UC assistant professor of geology and geography, will present her research, "Carbon Sequestration and Greenhouse Gas Emissions in Urban Ecosystems," at the Association of American Geographers annual meeting to be held April 9-13 in Los Angeles. The interdisciplinary forum is attended by more than 7,000 scientists from around the world and features an array of geography-related presentations, workshops and field trips.
University of Cincinnati student Shujie Wang has discovered that a good way to monitor the environmental health of Antarctica is to go with the flow – the ice flow, that is.
It's an important parameter to track because as Antarctica's health goes, so goes the world's.
"The ice sheet in Antarctica is the largest fresh water reservoir on Earth, and if it were totally melted, the sea level would rise by more than 60 meters. So it is quite important to measure the ice mass loss there," says Wang, a doctoral student in geography in UC's McMicken College of Arts & Sciences.
NEW ORLEANS, April 9, 2013 — The most serious ongoing water pollution problem in the Gulf of Mexico originates not from oil rigs, as many people believe, but rainstorms and fields of corn and soybeans a thousand miles away in the Midwest. An expert on that problem — the infamous Gulf of Mexico "Dead Zone" — today called for greater awareness of the connections between rainfall and agriculture in the Midwest and the increasingly severe water quality problems in the gulf.
San Diego, CA, April 9, 2013 – A new study published in the May issue of the American Journal of Preventive Medicine finds that Google searches for information across all major mental illnesses and problems followed seasonal patterns, suggesting mental illness may be more strongly linked with seasonal patterns than previously thought.
NEW ORLEANS, April 8, 2013 — Cuts in federal funding of nanotechnology research threaten to slow progress toward some of the field's greatest promises, including commercialization of sustainable new energy sources that do not contribute to global warming, an international authority in the field cautioned here today.
NEW ORLEANS, April 8, 2013 — The search for ways to use megatons of carbon dioxide that may be removed from industrial smokestacks during efforts to curb global warming has led to a process for converting that major greenhouse gas back into the fuel that released it in the first place. Research on the project was a topic here today at the 245th National Meeting & Exposition of the American Chemical Society (ACS), the world's largest scientific society.
