Tiny paddle oscillator senses the mass of a virus

...lf-dozen viruses -- and they believe the device is sensitive enough to notice just one. The research could lead to simple detectors capable of differentiating between a wide variety of pathogens, i ncluding viruses, bacteria and toxic organic chemicals. The experiment, an extension of earlier work in which si...

...through for diabetic children, who often have very sensitive skin." Proceeds from this financing will be primarily used to support Pelikan's commercialisation of the FDA-cleared Pelikan Sun TM lancing device, as well as the continued research and development of the company's fully-integrated glucose-testing a...

Molecular technique shows promise in destroying drug resistance in bacteria

...e bacterium resistant, then the bacterium could be sensitive to antibiotics again," Hergenrother said. The researchers' approach was to use a natural process called plasmid incompatibility. "If there is one plasmid in a cell and another one is introduced, then they compete with each other for resources," Herg...

Delays in cutting greenhouse gasses could harm environment

...verely damage many coral reefs, which appear to be sensitive to small temperature increases. Higher targets could cause warming beyond 2.5 degrees, which could affect many more ecosystems as well as the global ocean currents and ice sheets.

Army-funded effort examines androgen's role in bone loss

...id. "By overexpressing the receptor, we get a more sensitive response to androgen." Using collagen DNA cloned from rats as a promoter, Wiren was able to drive overexpression of the androgen receptor DNA in the skeleton and at a high level. "When we characterized how much of the receptor was present...

...aused tumor cells resistant to cisplatin to become sensitive to the anticancer drugs. They suggest that this strategy may be useful for treating human solid tumors that are drug resistant or even for increasing the efficacy of antitumor drugs in drug-sensitive tumors.

How receptors govern inflammatory pain

...lity of their AMPA channels was significantly more sensitive to heat or mechanical pressure on their inflamed paws than were either the strain of mice with "closed" AMPA channels or the normal mice. In similar tests, the researchers also found that the altered mice with more permeable AMPA channels showed evid...

Study shows stem cells can preserve vision

..., which interprets them. The retina contains light sensitive cells, known as rods, which make it possible for us to see in black and white and in low light, and cones, which are responsible for color and high-acuity vision. In diseases such as macular degeneration, it is these cells that are being destroyed. ...

'Blind' cells see the light; maybe someday humans will, too

...etically engineering surviving retinal cells to be sensitive to light has various advantages over the most comm...may allow us to cover the entire retina with light sensitive cells. If each nerve responds individually, you could do a very fine scan of the retinal field and c...

Flies on crack

...er, flies with the Lmo gene mutated were much more sensitive to crack cocaine and became immobile at much lower levels than normal fruit flies. Heberlein's group also showed that Lmo is normally produced in the pacemaker neurons that control 24-hour--or circadian--rhythms of sleep/wake cycles in flies. C...

Studies in Royal Society journals include stress in birds and depletion of medieval fish stocks

Bishop is not sure why rRNA breaks down more slowly, but he believes it may be because rRNA is protected by proteins that bind it into ribosomes- par...

Maihle and her team have developed highly sensitive biochemical assays that may one day be useful for detecting cancer cells anywhere in the body with a simple blood test to detect a tumor long before it is clinically detectable. These assays allow even current treatments to be more effective. T...

New approach studying protein structure could advance drug development

...difying their targeted proteins. The technique is sensitive enough to tell the difference between a ligand that's just sticking to the surface of a protein (a drug that may have no effect) and a ligand that's actually changing the structure (a drug that is more likely to be effective).
