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

...cted by stroke. The electrode connects to a pulse generator implanted below the collarbone. At the end of six weeks of intensive occupational therapy and completion of required follow-up periods, the device is removed. Doctors hope to see significantly more recovery in the participant group receiving stimu...

Scientists journey to southern Africa to unravel the secret world of elephant communication

...alinas is a farming area with a lot of tractor and generator noise in the background. But Etosha is a very quiet seismic environment, so we're hoping to get a more realistic assessment of how far elephant vibrations propagate in Namibia." Breeding and warning Scientists believe that an elephant's ability to ...

Life detection instrument passes key test on road to Mars

...lding at a deserted crossroads. With a noisy Honda generator providing power, they set up their experiments and, with six other colleagues, tested the integrated subcritical water extractor together with the MOA on samples from popular test sites such as the "Rock Garden" and the "Soil Pit."

Insulin pulses keep the liver lean

Insulin, a hormone long recognized as a generator of fat, also keeps fat in the liver under control, according to a new study in the July issue of Cell Metabolism. The newly discovered role for insulin may explain how an organ frequently flooded with the fat-building hormone normally stays trim and ...

A new twist on power walking

...evice that powers a geared DC motor that acts as a generator mounted on the frame. The load plate can be locked to stop the device from sliding up and down and generating electricity. To assure that the backpack wouldn't require users to expend too much additional metabolic energy, the scientists performed a v...

Salk researchers make fast strides towards understanding how our body controls walking

...as been known for some time that a central pattern generator (CPG) specialized groups of neurons in the spinal cord functions as the control and command center for these rhythmic movements. As such, the CPG lies at the heart of all locomotion. Remarkably, this circuitry functions without any input from the b...

Electrical stimulation boosts stroke recovery

..., a pacemaker-like device called an external pulse generator sends a low current through a wire to an electrode placed surgically atop the dura, the fibrous membrane covering the brain. The electrode rests above the motor cortex, the area in the brain corresponding to hand function. Surgeons pinpoint the site ...

Cholera pathogen reveals how bacteria generate energy to live

...ike two machines together imagine the turbine and generator of a hydroelectric dam. One is the source of energy; the other uses this energy to pump ions out of the cell," Barquera said. How the two machines are connected is one key question. In the first paper, published in the Journal of Bacteriology, Barq...
