Earth's Biogeochemical Cycles, Once in Concert, Falling Out of Sync

What do the Gulf of Mexico's "dead zone," global climate change, and acid rain have in common? They're all a result of human impacts to Earth's biology, chemistry and geology, and the natural cycles that involve all three.On August 4-5, 2009, scientists who study such cycles--biogeochemists--will convene at a special series of sessions at the Ecological Society of America (ESA)'s 94th annual meeting in Albuquerque, N.M.They will present results of ...

NYU Physicists Make Room for Oddballs

Here's a question. How many gumballs of different sizes can fit in one of those containers at the mall so as to reward a well-spent quarter? It's hard to believe that most people never consider it even when guessing the number of candies in a bowl at Halloween.But physicists at the Materials Research Science and Engineering Center at New York University recently developed a new way to help answer the question. They say the solution is found in how the particles pack in terms of how ... More at http://www.nsf.gov/news/news_summ.jsp?cntn_id=115358&govDel=USNSF_51 This is an NSF News item.

Of Mutts and Men

Domesticated animals provide man with benefits such as food, clothing and muscle power. Dogs, which descend from gray wolves that originated in Eurasia, were the first animals domesticated by man. Since that time, man has imposed a strong artificial selection pressure for desirable traits, resulting in the various dog breeds we have today.A recent study published in the August 3 issue of Proceedings of the National Academy of Sciences provides insight into the origin of some ...

New Hope for Fisheries on the Horizon?

Scientists have joined forces in a groundbreaking assessment on the status of marine fisheries and ecosystems.The two-year study, led by Boris Worm of Dalhousie University and Ray Hilborn of the University of Washington and including an international team of 19 co-authors, shows that steps taken to curb overfishing are beginning to succeed in five of the 10 large marine ecosystems that they examined.The paper, which appears in the July 31 issue of the journal Science, ...

Membrane Breaks Through Performance Barrier

Engineers have developed a new method for creating high-performance membranes from crystal sieves called zeolites; the method could increase the energy efficiency of chemical separations up to 50 times over conventional methods and enable higher production rates. The ability to separate and purify specific molecules in a chemical mixture is essential to chemical manufacturing. Many industrial separations rely on distillation, a process that is easy to design and implement but consumes ...

Researchers Link Jellyfish, Other Small Sea Creatures to Large-Scale Ocean Mixing

The ocean's smallest swimming animals, such as jellyfish, can have a huge impact on large-scale ocean mixing, researchers have discovered."The perspective we usually take is how the ocean--by its currents, temperature, and chemistry--is affecting animals," says John Dabiri, a Caltech bioengineer who, along with Caltech graduate student Kakani Katija, discovered the new mechanism. "But there have been increasing suggestions that the inverse is also important, ... More at http://www.nsf.gov/news/news_summ.jsp?cntn_id=115295&govDel=USNSF_51 This is an NSF News item.

NSF Selects University of Michigan Historian to Head Social, Behavioral and Economic Sciences

The National Science Foundation (NSF) has selected University of Michigan historian Myron Gutmann, director of the Inter-University Consortium for Political and Social Research, to head its directorate for Social, Behavioral and Economic Sciences (SBE). The directorate supports research that builds fundamental knowledge of human behavior, interaction, social and economic systems, and organizations and institutions.Gutmann, who specializes in historical demography and ...

What Scientists Know About Jewel Beetle Shimmer

"Jewel beetles" are widely known for their glossy external skeletons that appear to change colors as the angle of view changes. Now they may be known for something else--providing a blueprint for materials that reflect light rather than absorbing it to produce colors.Scientists at the Georgia Institute of Technology in Atlanta recently discovered jewel beetles change color because of the light-reflecting properties of the cells that make up their external skeletons, not ...

Remembering Walter Cronkite

The following is a statement by Arden L. Bement, Jr., Director, National Science Foundation.As the funeral for Walter Cronkite is held today in New York, we at the National Science Foundation want to add our voices to the many others who have saluted the veteran journalist and broadcaster. As the anchor of the CBS Evening News from 1961 and managing editor from 1963 until he retired in 1981, Cronkite brought the news of the world into our homes, often during turbulent ...

'Til Mortgage Do Us Part: The Science

On July 29, the National Science Foundation will examine the human dimensions of the nation's mortgage crisis in a virtual press briefing. One year after passage of the Housing and Economic Recovery Act of 2008 that authorizes $300 billion in new 30-year fixed rate mortgages for subprime borrowers, top economists answer media questions about how the psychology and neurobiology of individual investors affects the housing market.Yale University economist Robert Shiller, who predicted ...

Solar Cycle Linked to Global Climate

Establishing a key link between the solar cycle and global climate, research led by scientists at the National Science Foundation (NSF)-funded National Center for Atmospheric Research (NCAR) in Boulder, Colo., shows that maximum solar activity and its aftermath have impacts on Earth that resemble La Niña and El Niño events in the tropical Pacific Ocean.The research may pave the way toward predictions of temperature and precipitation patterns at certain times during the ...

Classifying "Clicks"

A new way to classify sounds in some human languages may solve a problem that has plagued linguists for nearly 100 years--how to accurately describe click sounds distinct to certain African languages. Cornell University professor Amanda Miller and her colleagues recently used new high-speed, ultrasound imaging of the human tongue to precisely categorize sounds produced by the N|uu language speakers of southern Africa's Kalahari Desert.  The research potentially could ...
