Study is looking at ways to help stroke survivors regain lost motor skills

...er the skin to below the collarbone, which is then hooked up to an implanted pulse generator. The device is turned on only during a participant's physical therapy sessions. Doctors hypothesize that the electrical charges help in one of two ways either by stimulating the growth of new nerve fibers in...

Innovative collaboration brings Arctic science into the classroom

Solutions that reduce death of marine life reeled in by International Smart Gear Competition

...tle behavior indicated sea turtles swim and become hooked in shallower waters than tuna, the target species of most longline commercial fishing. According to Duke University researchers, more than 200,000 loggerheads and 50,000 leatherbacks are accidentally caught annually by commercial longline fisheries. ...

Chickadees' alarm calls carry information about size, threat of predators

...chickadee than a great horned owl that has a large hooked beak and big talons. A great horned owl going after a chickadee would be like a Hummer trying to outmaneuver and catch a Porsche, "Templeton said. The chickadees also were exposed to a perched bobwhite quail, a non-predatory species, as a control a...

Secrets of the whale riders

...of an inch in length, and has five pairs of sharp, hooked claws. About 7,500 whale lice live on a single whale. Whale lice infest only whales, just as bird lice infest only birds and human lice infest only people. Recent genetic studies of head and body lice have revealed details of human evolution. Whale...

Nanoparticles, nanoshells, nanotubes: How tiny specks may provide powerful tools against cancer

... In the study that Lowery reports, the researchers hooked "Y"-shaped anti-HER2 antibodies to nanoshells, and the antibody bound to HER2 over-expressing breast cancers. They then applied these immunonanoshells to the top of laboratory breast cancer cells, and used laser light to heat the agent. Researchers t...

Student scientists create living bacterial photographs

...blue-green algae to the E. coli cell surface. They hooked the light receptor up to a sensor in E. coli that normally senses salt concentration. Instead of sensing salt, the bacteria could sense light. The light receptor was then connected to a system in the bacteria that makes pigments. When light strikes t...

'Fish with chips' reporting from ocean top highlights at Census of Marine Life mid-point

...Tuna and Billfish since 1950:Using records of fish hooked on longlines in openoceans, researchers found the abundance and speciesdiversity of large pelagic fish declined rapidly overthe past 50 years. Global concentrations of such keypredators such as tuna, marlin, and swordfishdecreased dramatically worldw...

Live wires

Co-author and PNNL scientist Jeff Mclean, who manages the microbial fuel cell laboratory, said that small changes in fuel cell design and culture conditions have already shown large improvements in the efficiency of the fuel c...

Equine Medical Center records successful year for neonatal foals

... unusual to see a concerned mother nuzzling a baby hooked up to an array of tubes and wires and electronic medical equipment. The Equine Medical Center has operated a very successful foal-watching program for about 15 years where community volunteers come in to sit with the foals, doing everything from c...

Tiny worm provides model for the genetics of nicotine dependence

...xperiments which establish that C. elegans can get hooked on nicotine. Like humans, the nicotine-sensitive worms showed acute responses to nicotine exposure, as well as tolerance, sensitization and withdrawal. "It turns out that worms exhibited behavioral responses to nicotine that parallel those observed ...

Gene chip technology shows potential for identifying life-threatening blood infection

... accident or fall. Because these patients are also hooked up to IV fluids, catheters or ventilators, they are also prone to bacterial infections, including pneumonia, that can quickly spiral out of control and lead to sepsis. Although both conditions are life-threatening because of their threat to major o...

Wheat can fatally starve insect predators

...nts for the insect. Instead, the promoter would be hooked up to a lectin or toxin gene and inserted into the cells. When larvae manipulate the promoter, they would receive gut-altering lectin instead of nutrients. To advance their investigation into developing more resistant plants, the researchers are be...

Complex channels

As the index finger was held steady in a small harness, each subject was asked to use the finger to follow the outline of a sinusoidal curve, with ...

Light sticks may lure turtles to fishing lines

...ad turtles die every year when they get tangled or hooked in commercial fishing longlines meant for tuna or swordfish. New research suggests a possible reason why turtles swim into the lines. The glowing light sticks that lure fish to longlines also attract turtles, according to a University of North Carol...

Turning the tables in chemistry

...ces. Like flies, mosquito feet are equipped with hooked claws for clinging to skin. Like geckos, they have hairy pads on their feet that stick to nearly any smooth surface with a velcro-like grip. But it's their ability to walk on water that really makes mosquitoes stand out in the animal kingdom. Both ...
