Solving Mystery of How DNA Strands Separate
Cornell researchers have answered a fundamental question about how two strands of DNA separate to start a process called replication, in which genes copy themselves. The research examined the role of an enzyme called a helicase, which plays a major role in separating DNA strands.

These shallow ponds are important indicators of environment change and are especially susceptible to the effects of climate change because of their low water volume.

Tough Tubes: Carbon Nanotubes Endure Heavy Wear and Tear
The ability of carbon nanotubes to withstand repeated stress yet retain their structural and mechanical integrity is similar to the behavior of soft tissue, according to a new study from Rensselaer Polytechnic Institute. When paired with the strong electrical conductivity of carbon nanotubes, this ability to endure wear and tear, or fatigue, suggests the materials could be used to create structures that mimic artificial muscles or interesting electro-mechanical systems, researchers said.

Archaeologists Rescue Ancient Civilization from Rising Nile
Archaeologists have discovered a gold processing center along the middle Nile and a cemetery that show the first sub-Saharan kingdom controlled more territory than previously thought. The remains of the kingdom of Kush (1500-200 BC) are being covered, however, by the rising waters from a newly built dam.

Brain's Voluntary Chain-of-command Ruled by Not One but Two Captains
A probe of the upper echelons of the human brain's chain-of-command has found strong evidence that there are not one but two complementary commanders in charge of the brain, according to neuroscientists at Washington University School of Medicine in St. Louis.

Scientists Develop a "Control Switch" for Protein Activity
Weizmann Institute scientists have developed a unique "switch" that can control the activity of any protein, raising it several-fold or stopping it almost completely. The method provides researchers with a simple and effective tool for exploring the function of unknown proteins.

Individual Differences in Sleep Structure are Biologically Determined
Sleeping pattern variability has long been attributed to differences in several non-biological factors. Now a study from the Sleep and Performance Research Center at Washington State University Spokane, Wash., has shown that these individual differences are in large part biologically determined and may even prove to be genetic in origin.

Virologists Show How "Memory" T Cells Curb the Spread of Viruses Throughout the Body
A scientific discovery by Fox Chase Cancer Center researchers helps explain how "memory" T cells protect the body from viral diseases. The research published today in Proceedings of the National Academy of Science Online Early Edition shows lymph nodes are not just organs where immune cells reside and proliferate, but also are the sites where a major fight against the spread of an invading virus occurs.

Global Climate Change and Toxic Chemicals: A Potentially Lethal Combination
As temperature influences the toxic effects of chemicals, so does chemical exposure influence the temperature tolerance of an organism. The consequences of this harmful reciprocal relationship on four freshwater fish are explored in a new study published in the latest issue of Environmental Toxicology and Chemistry.

Scientists Report on Last Summer's "Stealth" Tsunami
Though categorized as magnitude 7.8, the earthquake could scarcely be felt by beachgoers that afternoon. A low tide and wind-driven waves disguised the signs of receding water, so when the tsunami struck, it caught even lifeguards by surprise. That contributed to the death toll of more than 600 persons in Java, Indonesia.

Nanotube Adhesive Sticks Better than a Gecko's Foot
Mimicking the agile gecko, with its uncanny ability to run up walls and across ceilings, has long been a goal of materials scientists. Researchers at Rensselaer Polytechnic Institute and the University of Akron have taken one sticky step in the right direction, creating synthetic "gecko tape" with four times the sticking power of the real thing.

Fortran and Scientific Programming: Celebrating 50 Years of Mutual Growth
Over half of the century of its existence, the evolving Fortran has been the traditional and major language for scientific programming and it has played a significant role in the research on programming languages and compilers for scientific computing. To mark this occasion, a special issue of Scientific Programming on the role of Fortran in the scientific programming discipline is being published by IOS Press this month.
