...og muscle by a computer and motor. The muscle then sends a signal back to the computer, and the virtualmodel translates the reaction. The biological/computer fusion creates an electrical and mechanical information loop that provides researchers with a better idea of how the muscle reacts to certain mechani...DARPA grant supports research toward realizing tissue regeneration
...months. When a salamander loses a limb, the wound sends out molecular signals that prompt surrounding tissue to begin production of new progenitor cells, also referred to as precursor cells. These progenitor cells continue to divide and form a large pool of cells at the wound site, called a blastema, that...Wisconsin scientists discover a master key to microbes' pathogenic lifestyles
...thogenic yeasts. "This is a global regulator that sends signals down a molecular chain of command and governs a series of vital genetic programs," Klein explains. "It leads to changes in the organism's metabolism, cell shape, cell wall composition, and changes in virulence gene expressions." These change...How does the brain know what the right hand is doing?
...hypothesis says that the brain monitors signals it sends to the muscles telling them how strongly to contract, and uses this to predict where the limb has moved to; (2) the inflow hypothesis suggests that the brain relies on information from sensors within tissues that say how far a limb has moved. While t...Electrical stimulation boosts stroke recovery
...ker-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.

...gh polar orbit, Envisat's Radar Altimeter-2 (RA-2) sends 1800 separate radar pulses down to Earth per second then records how long their echoes take to bounce back. The sensor times its pulses' journey down to under a nanosecond to calculate the distance to the planet below to an accuracy of two centimetre...Adaptation to oxygen deprivation elucidates tumor physiology
...dicine. "The cell simply turns off the spigot that sends fuel to the mitochondria." Both studies found that cells repress mitochondria function and oxygen consumption under low oxygen conditions through the enzyme pyruvate dehydrogenase kinase 1 (PDK1). Dang's group showed that, under hypoxic conditions,...New research shows bats have complex skills to deal with 'clutter'
...the bat gets closer to what could be an insect, it sends out an array of quick repetitive pulses, called sonar strobe groups. Finally, when it has locked onto the bug, right before scooping it up, the bat shoots a rapid fire series of sounds called the final buzz. "In each case we found that the bats spent...Obese people are more sensitive to pain, suggests study
...nd the sural nerve. When the brain senses pain, it sends a message to the body to contract and move the muscles in order to get away from the source of the pain. "This kind of evaluation is in some ways a more objective way of measuring the body's response to pain, as opposed to simply asking someone if th...Disease damages wheat roots, thwarts water uptake

"What I've seen in my experiments so far is it (the disease) damagesroot growth," he said. "Once infected, the roots d...Rochester scientists develop fast-working biosensor
...as a "molecular harpoon," Miller said. The E. coli sends out the harpoon into a cell. Once it is in the cell, the Tir then binds with an E. coli protein called Intimin. A similar process occurs between the Tir placed on the chip and any E. coli in the sample being tested. The binding of the probe and the b...UW scientists unravel critical genetic puzzle for flu virus replication
...to make virions, the particles a virus creates and sends forth to infect cells, that puzzle has been resolved. The new work, which is reported in this week's (Jan. 26, 2006) edition of the journal Nature, is important because it presents opportunities to design new antiviral drugs and harness flu viruses f...Nuclear medicine imaging allows prediction of breast cancer patients' response to hormonal treatment
...reotide, which binds to somatostatin receptors and sends out flashes of light detected by a gamma camera, researchers were able to create an image of the presence of hormone-sensitive lesions in a patient's body.

Endosomal sorting is an important way in which cells control Notch activity, and when Tsg101 mutant cells are unable to correctly sort Notch protein, it becomes hyperactivate...Researchers find gland that tells fruit flies when to stop growing
