NEW ORLEANS, April 8, 2013 — The Gulf of Mexico may have a much greater natural ability to self-clean oil spills than previously believed, an expert in bioremediation said here today at the 245th National Meeting & Exposition of the American Chemical Society (ACS), the world's largest scientific society.

The Gulf of Mexico may have a much greater natural ability to self-clean oil spills than previously believed, according to Terry Hazen, University of Tennessee-Oak Ridge National Laboratory Governor's Chair for Environmental Biotechnology.
The bioremediation expert presented his Deepwater Horizon disaster research findings at the 245th National Meeting and Exposition of the American Chemical Society (ACS), the world's largest scientific society.
The rapid growth of the solar power industry over the past decade may have exacerbated the global warming situation it was meant to soothe, simply because most of the energy used to manufacture the millions of solar panels came from burning fossil fuels. That irony, according to Stanford University researchers, is coming to an end.
Franz, graduate students Megan Danielewicz, Diana Wong and Lisa Anderson, and undergraduate student Jordan Boothe screened 83 compounds for their effects on growth and oil production in four strains of microalgae. They identified several that could boost oil production by up to 85 percent, without decreasing growth.
Among the promising compounds were common antioxidants such as epigallocatechin gallate, found in green tea, and butylated hydroxyanisole (BHA), a common food preservative.
The study analyzes the potential of social networks such as Twitter and Facebook to coordinate people. In recent years there have been a number of examples of how social networks have served to mobilize volunteers during natural disasters, political campaigns, health emergencies, etc. But can we really depend on the use of social networks to carry out these tasks? And if it is possible, what is the risk that this strategy will fail?
Alexandria, VA – For decades, scientists have used sophisticated instruments and computer models to predict the nature of droughts. With the threat of climate change looming large, the majority of these models have steadily predicted an increasingly frequent and severe global drought cycle. But a recent study from a team of researchers at Princeton University and the Australian National University suggests that one of these widely used tools — the Palmer Drought Severity Index (PDSI) — may be incorrect.
NEW ORLEANS, April 8, 2013 — Technology that enlists natural soil bacteria as 21st century roughnecks now is commercially available and poised to recover precious oil remaining in thousands of exhausted oil wells, according to a scientist who spoke here today. His report on a process termed microbially enhanced oil recovery (MEOR) was part of the 245th National Meeting & Exposition of the American Chemical Society, the world's largest scientific society.
An analysis of U.S. Supreme Court decisions suggests "historical amnesia" regarding the growing power of speech rights for corporations in electronic media, versus the First Amendment rights of individuals. Jeff Blevins, associate professor and head of the University of Cincinnati's Department of Journalism, will present his research on Tuesday, April 9, at the 58th annual convention of the Broadcast Education Association in Las Vegas.
PITTSBURGH—Surgical robots could make some types of surgery safer and more effective, but proving that the software controlling these machines works as intended is problematic. Researchers at Carnegie Mellon University and the Johns Hopkins University Applied Physics Laboratory have demonstrated that methods for reliably detecting software bugs and ultimately verifying software safety can be applied successfully to this breed of robot.
Imagine a tent that blocks light on a dry and sunny day, and becomes transparent and water-repellent on a dim, rainy day. Or highly precise, self-adjusting contact lenses that also clean themselves. Or pipelines that can optimize the rate of flow depending on the volume of fluid coming through them and the environmental conditions outside.
NEW ORLEANS, April 7, 2013 — Scientists today described technology that accelerates microalgae's ability to produce many different types of renewable oils for fuels, chemicals, foods and personal-care products within days using standard industrial fermentation. The presentation was part of the 245th National Meeting & Exposition of the American Chemical Society (ACS), the world's largest scientific society. The meeting, with 12,000 presentations on advances in science and other topics, continues here through Thursday.
NEW ORLEANS, April 7, 2013 — Families can be key players in a revolution needed to feed the world, and could save money by helping to cut food losses now occurring from field to fork to trash bin, an expert said here today. He described that often-invisible waste in food — 4 out of every 10 pounds produced in the United States alone — and the challenges of feeding a global population of 9 billion in a keynote talk at the 245th National Meeting & Exposition of the American Chemical Society, the world's largest scientific society.
NEW ORLEANS, April 7, 2013 — The mystery of how arsenic levels in beer sold in Germany could be higher than in the water or other ingredients used to brew the beer has been solved, scientists announced here today at the 245th National Meeting & Exposition of the American Chemical Society, the world's largest scientific society. The meeting, which features almost 12,000 reports and other presentations, continues through Thursday.
