To translate touch, the brain can quickly rearrange its sense of the body

...plying the vibration, suggesting a very strong and fast link between the brain systems for touch and body position. The observations showed that abnormal input into one of the body's sensory systems produced a rapid and profound change in another sensory system: The brain had changed the way it interpret...

Motor transport in bio-nano systems

...rovided the motors leave the filament sufficiently fast after they have reached its 'plus' end. However, both types of systems exhibit a characteristic, intermediate motor concentration for which the cargo transport is optimal. With the models the researchers can predict how this optimal motor concentrati...

'Bionic' arm gives amputee sense of touch

Five journals published by BioMed Central received their first impact factors this year. BMC Bioinformatics, with an impact factor of 5.42, has reinforced its reputation as one of...

Open Access journals get impressive impact factors

Ocean climate predicts elk population in Canadian Rockies

...e wolves, their main predator, cannot kill and eat fast enough to wipe out the whole population. Also, wolves tend to kill one another as their available prey dwindles, so a stasis is maintained naturally. Nevertheless, Hebblewhite is excited about his findings because they provide a deeper understanding...

Discovery of New Dopamine Action May Yield Alternative Psychiatric Drugs

...mitters relay messages to the brain in two speeds: fast and slow," said lead author of the study Jean-Mart...s of receptors -- one class that transmits signals fast and another that acts through signaling pathways to relay messages more slowly. Dopamine receptors ...

Atmosphere may cleanse itself better than previously thought

...ause they are so reactive ?which means they vanish fast ?and also because we don't have complete knowledge of all the sources that produce them yet." The experiments, which Sinha and Matthews performed at UCSD, used a laser technique that allowed the team to look at the OH radical-producing molecules in ...

Rabies spread speeds up

... establishing a new vaccine barrier. And given how fast raccoon rabies could spread, Real and colleagues make a strong case that halting its western march depends on a strategy based on early detection and high-powered intervention programs - a sensible approach for any infectious disease. ### Citation:...

Whole-body MRI Takes Less Than 20 Min To Scan A Patient's Entire Body For Cancer Spread To Bone

Thai spice helps cut blood sugar swings

...bodies get at the sugars?If the body experiences a fast infusion of sugars, a lot of insulin is required. If the sugars are metabolized more slowly, the insulin is released gradually. This is a crucial difference, as far as obesity is concerned: Fast sugar is worse for you; slower is better." Besides the...

Breakthrough isolating embryo-quality stem cells from blood

...ready test 3,600 cells per minute. This is not yet fast enough for industrial separation of millions of high grade stem cells, but it promises a realistic alternative to embryo use if it can be scaled up. Meanwhile, it is already being used to isolate low-grade stem cells which can develop into skin. In c...

New design : complete

...a. "Those who are running to finish the race very fast don't have time to drink a lot of water along the way," Dr. Levine said. "Those who are not running the race competitively tend to stop at every water station and take a drink. Over the course of a long race, they can dilute themselves." In addition...

Bush, Cheney and Rumsfeld are now species of slime-mold beetles -- but strictly in homage

...a. "Those who are running to finish the race very fast don't have time to drink a lot of water along the way," Dr. Levine said. "Those who are not running the race competitively tend to stop at every water station and take a drink. Over the course of a long race, they can dilute themselves." In addition...

Too much water may be as dangerous as too little during long-distance athletic events

Discovery clarifies role of peptide in biological clock

...t, rather than a neurotransmitter, associated with fast events, Herzog said. "We're trying to understand the mechanics of how the system synchronizes and the secondary messenger systems as well," Herzog said. "We're getting closer to the heart and soul of circadian rhythmicity by uncoupling the (biologic...

Product improves peptide identification for proteomics research

... analysis, which require excellent sensitivity and fast scanning capability." The LC/MSD Trap XCT Ultra, which is based on an advanced multipole ion trap technology, has a full-scan MS/MS sensitivity specification of 250 femtograms for reserpine. The system also has two new data-dependent neutral-loss an...

After a time-shift, mixed signals from the circadian clock

... distinct pattern of activity that corresponded to fast resetting of the clock. Perhaps contributing to the different behavior of the two groups of clock cells are the effects on these cells of the neurotransmitter GABA, which the researchers found to excite the cells of the dorsal SCN while inhibiting n...

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

...hrough the ground at 1,300 feet a second--twice as fast as in Etosha National Park. Because slower seismic waves maintain their integrity longer, it is possible that elephant vibrations in Etosha would travel farther than in Salinas. "After we did the Salinas study, we realized that there were other thin...

Duke engineers develop new 3-D cardiac imaging probe

... blood vessels and heart tissue. TEE is a safe and fast diagnostic technique. However, current TEE systems can quickly generate only two-dimensional cross-sectional images. This limitation makes it impractical for use in guiding therapeutic treatment devices such as ablation probes that burn off damaged ...
