Brown University Scientists Discover New Principle in Material Science
Wed, 14 Apr 2010 14:29:00 -0500
A
research team led by Brown University engineers has discovered a new mechanism that governs the peak strength of nanostructured metals. The team found that the deformation of nanotwinned metals is characterized by the motion of highly ordered, necklace-like patterns of crystal defects called dislocations. The finding, published in Nature, could lead to stronger and more ductile metals.

To make large sheets of carbon available for light
collection, Indiana University-Bloomington chemists have devised an unusual solution--attach what amounts to a 3-D bramble patch to each side of the carbon sheet. Using this method, the scientists say they were able to dissolve sheets containing as many as 168 carbon atoms, a first.

A new
study from North Carolina State University shows that size plays a key role in determining the structure of certain hollow nanoparticles. The researchers focused on nickel nanoparticles, which have interesting magnetic and catalytic properties that may have applications in fields as diverse as energy production and nanoelectronics.

New research by a team of ecologists and
hydrologists shows that water temperatures are increasing in many streams and rivers throughout the United States. The research, published in the journal Frontiers in Ecology and the Environment, documents that 20 major U.S. streams and rivers--including such prominent rivers as the Colorado, Potomac, Delaware and Hudson--have shown statistically significant long-term warming.

A team of archaeologists is
excavating a key site from the prehistoric society that formed the foundation of urban life in the ancient Middle East. The site already has yielded evidence of trade in obsidian, rich agricultural production and the development of copper processing--all of which flourished long before people domesticated pack animals for transportation or invented the wheel.

Convergent Evolution in Lignin Biosynthesis: Tools for Re-engineering Biomass Composition
Thu, 15 Apr 2010 10:29:00 -0500
The plant cell wall component
lignin, a complex phenolic polymer, is valued for its energy content, but inhibits biomass breakdown for cellulosic ethanol. In research published in the Plant Cell, investigators identify an alternative pathway for synthesis of syringyl lignin in the lycophyte Selaginella moellendorffii. This pathway, a likely example of convergent evolution, could be used to alter lignin composition in transgenic plants.

In the first barcoding survey of
sand flies in Panama, scientists at the Smithsonian Tropical Research Institute and Gorgas Memorial Laboratories identified 20 sand fly species from Barro Colorado Island. Two species carried Leishmania naiffi, a parasite that causes cutaneous leishmaniasis. Three species carried Wolbachia, a bacterial parasite of insects that could contribute to a strategy to control the flies and limit disease transmission.

Current observational tools cannot account for roughly half of the heat that is believed to have built up on Earth in recent years, according to a "Perspectives" article in this week's issue of the journal Science.
Scientists at the National Center for Atmospheric Research (NCAR) in Boulder, Colo., warn that satellite sensors, ocean floats, and other instruments are inadequate to track this "missing" heat, which may be building up in the deep oceans or ...
