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

...e affected by stroke. The electrode connects to a wire running under 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...

Livestock grazing study finds moderate grazing beneficial to Great Basin plant communities

...losure sites--four-acre parcels enclosed by barbed wire to keep out livestock--were built at that time. Today, 16 of those sites remain intact and provided the basis for the study. "There have been a lot of exclosure-type studies," Perryman said "But this is one of the longest, if not the longest, study o...

Isotron licenses ORNL cancer treatment technology

...Division reduced the diameter of the source -- the wire that contains the radioisotope -- by more than hal...aking the source capsules that are attached to the wire that allows for the insertion of the radioisotope. Isotron's method combines the radioisotope source...

Transgenic plants remove more selenium from polluted soil than wild plants, new tests show

...rs in the bud, and that netting and buried chicken wire were used to keep wildlife away from the plants. "One of the challenges in developing transgenic plants for remediation is engineering them in such a way that the risk of gene transfer is reduced or eliminated," said Banuelos. Terry said that techn...

Technological revolutions in sensors, robotics, and telecommunications allow new views of ocean

...ers hope that this new technology will allow us to wire the entire ocean basins in the future. "It's hard to understand how important it is until you compare it with how we work in the oceans today," says Bellingham. "We go to sea on ships and visit particular places for short periods of time. But what ...

Virginia Tech patents advance microprocessors, vaccines, vision, vibration control, more

... old technology uses a magnetic core and insulated wire as a ballast. An electronic ballast is 30 percent more efficient, but is more expensive. There are literally hundreds, or even thousands, of patents for electronic ballast improvements particularly to make a ballast component that is both efficient ...

One year after groundbreaking, desert research center takes shape on the Israeli-Jordanian border

...lf of the facility in Israel and half in Jordan. A wire fence separates the border from the Dead Sea to the Red Sea, but in February, Israel and Jordan agreed to take down the barrier at the project site so that construction could move forward. When fully operational, the research center will have three l...

Grizzlies set to invade high Arctic?

... mud. And from the cabin's outside walls and a guy wire attached to the roof they collected two intriguing brown hairs. These were sent for analysis to Wildlife Genetics International Inc. in Nelson, British Columbia, one of the world's premier bear DNA labs. The result: the genetic analysis pointed to a ...

DNA 'packaging' linked with cancer

...proteins keep the string of DNA -- really, a stiff wire with component nucleotides -- tightly compressed; if the proteins are removed, the genes spring out like a jack-in-the-box. When the researchers disassembled a cell's skeletal elements -- microtubules, actin and intermediate filaments -- not only did...

Molecular testing impact: Heart transplant patients benefit from new technology, easier monitoring

...ion. During this invasive procedure, a bioptome a wire with small clippers is inserted into a vein in the patient's neck or groin and threaded through blood vessels into the heart. Small pieces of the heart muscle are clipped off and sent for laboratory evaluation for microscopic evidence of rejection. ...

Device creates electricity and treats wastewater

...he cathode chamber, and electrons passing over the wire between electrodes to create a current. Oxygen is added to the cathode chamber, and on the electrode there is a reaction of electron plus proton plus oxygen to form water. Catalysts, such as platinum, are needed on both electrodes to promote the re...

It's electric: Cows show promise as powerplants

... the movement of electrons across the resistor and wire that connects the two electrodes, creates electrical current. The anode chamber was filled with rumen fluid and cellulose, which served as a food source for the microorganisms. Cellulose is plentiful on most farms, as harvesting usually leaves behind...

Cyberkinetics, Case to develop system to help restore extremity function

...esponsible for movement, the motor cortex. A small wire connects the sensor to a pedestal that is placed on the skull, extending through the scalp. An external cable connects the pedestal to a cart containing computers, signal processors and monitors that enable the study operators to determine how well ...

Radical approach to cardiac resynchronization shows promise

Brainstem blocks pain to protect key behaviors

... NPP, studied adult male rats in containers with a wire mesh floor that enabled them to deliver radiant heat to one hind paw. The heat caused no damage but was annoying enough to make the animal withdraw that paw within seconds. When the rats ate, however, they postponed retracting the heated paw for ...

Team led by Carnegie Mellon University scientist finds first evidence of a living memory trace

Once this stimulus is removed, traces of that excitation/inhibition pattern so-called Hebbian reverberations sho...

Robo-rodent gets 'touchy-feely'

... kind. "Essentially we put in the sensors and then wire them up through the robots 'brain', its CPU. We just switch it on without giving it instructions of any kind," says Simon Bovet, a Ph.D. student at the University of Zurich. When he threw the switch his robot started moving about the room but always ...
