Nerve stimulation therapy alleviates pain for chronic headache

A novel therapy using a miniature nerve stimulator instead of medication for the treatment of profoundly disabling headache disorders improved the experience of pain by 80-95 percent, according to a new study from the University of California, San Francisco and the National Hospital for Neurology and Neurosurgery in London.

Dry adhesive based on carbon nanotubes gets stronger, with directional gripping ability

The race for the best "gecko foot" dry adhesive got a new competitor this week with a stronger and more practical material reported in the journal Science by a team of researchers from four U.S. institutions.

Digital zebrafish embryo provides the first complete developmental blueprint of a vertebrate

Researchers at the European Molecular Biology Laboratory (EMBL) have generated a digital zebrafish embryo - the first complete developmental blueprint of a vertebrate. With a newly developed microscope scientists could for the first time track all cells for the first 24 hours in the life of a zebrafish. The data was reconstructed into a three-dimensional, digital representation of the embryo. The study, published in the current online issue of Science, grants many new insights into embryonic development.

Keeping herpes infection in check: Pitt researchers describe immune system strategies

PITTSBURGH, Oct. 9 – Herpes simplex virus type I can cause bouts of cold sores, blindness and potentially lethal encephalitis when it reawakens from a quiescent state in the nerve cells it infects.

To prevent these consequences, the stealthy virus is kept under constant guard by the immune system, say University of Pittsburgh scientists. Their research challenges the once common notion that latent HSV-1 in sensory neurons is invisible to the immune system.

Smithsonian perspective: Biodiversity in a warmer world

Will climate change exceed life's ability to respond? Biodiversity in a Warmer World, published in the Oct. 10, 2008 issue of the journal, Science, illustrates that cross-disciplinary research fostered by the Smithsonian Tropical Research Institute in Panama clearly informs this urgent debate.

Ripple effect: Water snails offer new propulsion possibilities

A UC San Diego engineer has revealed a new mode of propulsion based on how water snails create ripples of slime to crawl upside down beneath the surface.

Eric Lauga, an assistant professor of mechanical and aerospace engineering at the Jacobs School of Engineering, recently published a paper in the journal Physics of Fluid called "Crawling Beneath the Free Surface: Water Snail Locomotion," that explains how and why water snails can drag themselves across a fluid surface that they can't even grip.

AAAS satellite image analysis reveals South Ossetian damage

Promising new material that could improve gas mileage

EVANSTON, Ill. --- With gasoline at high prices, it's disheartening to know that up to three-quarters of the potential energy you are paying for is wasted. A good deal of it goes right out the tailpipe instead of powering your car.

Now a Northwestern University-led research team has identified a promising new material that could transform a technology that currently cools and heats car seats -- thermoelectrics -- into one that also efficiently converts waste heat into electricity to help power the car and improve gas mileage.

Children with cystic fibrosis not well covered by guidelines for vitamin D needs

Existing recommendations for treating vitamin D deficiency in children with cystic fibrosis (CF) are too low to cover the serious need, leaving most at high risk for bone loss and rickets, according to researchers at Johns Hopkins Children's Center.

Spallation Neutron Source sends first neutrons to 'Big Bang' beam line

OAK RIDGE, Oct. 9, 2008 -- New analytical tools coming on line at the Spallation Neutron Source, the Department of Energy's state-of-the-art neutron science facility at Oak Ridge National Laboratory, include a beam line dedicated to nuclear physics studies.

The Fundamental Neutron Physics Beam Line (FNPB) has opened its shutter to receive neutrons for the first time. Among the nuclear physics studies planned for the new, intense beam line are experiments that probe the neutron-related mysteries associated with the "Big Bang."

Evolution of virulence regulation in Staphylococcus aureus

Scientists have gained insight into the complex mechanisms that control bacterial pathogenesis and, as a result, have developed new theories about how independent mechanisms may have become intertwined during evolution. The research, published by Cell Press in the October 10th issue of the journal Molecular Cell, may lead to strategies for developing more effective therapeutics against the human pathogen responsible for most of the antibiotic-resistant infections contracted in the community.

New findings may improve treatment of inherited breast cancer

Scientists have identified some of the elusive downstream molecules that play a critical role in the development and progression of familial breast cancer. The research, published by Cell Press in the October 10th issue of the journal Molecular Cell, also identifies a compound found in grapes and red wine as an excellent candidate for treatment of some forms of breast cancer.

Researcher at NYU Langone's Skirball Institute available to discuss finding published in Cell

New York City, NY, October 9, 2008 - Over the past several decades, many laboratories have studied the communication between nerve cells and muscle fibers that are crucial to form and maintain neuromuscular synapses. Now, researchers at the at the NYU Langone Medical Center have found that a protein named Lrp4 is the missing link that allows communication between two crucial molecules—one derived from the nerve and the other from muscle—that enables the formation of the synapse.

Case Western Reserve University research finds drug candidate slows age-related macular degeneration

CLEVELAND – Research results from the Case Western Reserve University School of Medicine show that the progression of age-related macular degeneration (AMD) is markedly slowed in new laboratory-engineered mice when they received treatments of retinylamine, a trial drug that has been tested in a medical school lab. AMD is a leading cause of vision loss in Americans 60 years of age and older.

The findings from the National Eye Institute-funded research are reported in the prestigious Journal of Biological Chemistry.

Turning freshwater farm ponds into crab farms

Work by researchers at North Carolina State University is leading to a new kind of crab harvest – blue crabs grown and harvested from freshwater ponds, instead of from the sea.

Crab lovers shouldn't worry, researchers say, because the pond-raised crabs look and taste just like their ocean-raised brethren.
