St. Jude study solves mystery of mammalian ears

...th mammals and non-mammals to swing back and forth quickly in a steady rhythm. In mammals, the rod-shaped body of the outer hair cell contracts and then vibrates in response to the sound waves, amplifying the sound. In a previous study, Zuo and his colleagues showed that a protein called prestin is the mot...

FDA sees nanotech challenges in every product category it regulates

...ology Task Force’s recommendations. Without moving quickly and building on the recommendations in the Task Force report, FDA will not be able to keep pace with today’s rapidly developing nanotechnology market or engender consumer and investor confidence in emerging products.” Just released, this is the firs...

Agent slows aging in mice

...Maine. The scientists were surprised to find so quickly that one agent showed promise: NDGA, a compound derived from creosote bushes. These common North American desert shrubs have been traditionally used by Native Americans as healing remedies. The preliminary results, to be published in August in t...

Soils offer new hope as carbon sink

...le to change quickly) or stable – depending on how quickly they break down and convert into carbon dioxide," he said. "Labile carbon like crop residue, mulch and compost is likely to last two or three years, while stable carbon like agrichar will last up to hundreds of years. "This is significant for f...

Hormone helps mice 'hibernate,' survive starvation

...ng mice without PPAR-alpha become hypoglycemic and quickly die. In analyzing the molecular impact of PPAR-alpha in mice, the researchers found that it stimulates production of FGF21, a member of a hormone family that has been shown to lower blood glucose levels in diabetic and obese mice. FGF21, in tur...

Largest synthetic gene ever built offers insights into anti-malarial drug resistance

...oquine (CQ), a synthetic version of quinine, which quickly became the treatment of choice because it was inexpensive − now seven cents a dose − and needs no refrigeration. The drug works by preventing heme crystallization, which destroys the parasite by building up toxic levels of non crystalline heme. ...

Breakthrough developments in rheumatoid arthritis reported

...n. “We have the tools to get at these genes rather quickly now,” he said. “The more patients and controls that we have, the more power we will have to pull out new genes and make associations.” In another major breakthrough, scientists have discovered the importance of a substance called citrulline as ...

Researchers examine carbon capture and storage to combat global warming

... that we can take fossil fuels out of the mix very quickly is unrealistic. We're reliant on fossil fuels, and a good pathway is to find ways to use them that don't create a problem for the climate.'' Carbon capture has the potential to reduce more than 90 percent of an individual plant's carbon emissions,...

Genome of Clostridium botulinum reveals the background to world's deadliest toxin

...hich are serious human infections. The host can be quickly overpowered and, in some cases, killed by the toxin, and C. botulinum has a new food source. "Although in the same group as Clostridium difficile — the Cdiff superbug — C. botulinum has a genome that is remarkable because it is so stable," commen...

Moths mimic sounds to survive

...l as the sounds made by the bats. All the bats quickly learned to avoid the noxious moths first offered to them, associating the warning sounds with bad taste. They then avoided a second sound-producing species even though it was not chemically protected. This is similar to the way birds avoid butterfli...

Smallpox outbreak: How long would it take for vaccines to protect people? Would it work?

...ax. "Another purpose of the study is to see how quickly people can be protected against smallpox after a release of smallpox into the environment," Frey said. Dryvax® vaccine is the original Food and Drug Administration (FDA) licensed vaccine that was used to protect humans against smallpox disease. In...

Amphibians in losing race with environmental change

...of evolution and the inability of species to adapt quickly enough can explain most of the causes that are leading one species after another of amphibians into decline or outright extinction, say researchers from Oregon State University, in a study published today in the journal BioScience. "We know that t...

Nitric oxide: Key to cardiovascular and pulmonary function and drug effectiveness

...cellular signals. Once activated the receptors are quickly turned-off by an enzyme called a G protein-coupled receptor kinase. This process is called desensitization and can limit the effectiveness of many drugs, such as opiates for pain and adrenaline for asthma, and is further associated with numerous dise...

As described in this week's online issue of the Proceedings of the National Academy of Sciences, the first applications of the technique offer a gli...

A new portable biosensor detects traces of contaminants in food more quickly and cheaply

...1 micrograms per litre), and this can be done more quickly and cheaply than is the case of the chromatographs which are used today in food safety laboratories. As regards the detection of antibiotics, the sensor has a sensitivity of 1 microgram per litre for whole milk, while the legislation allows a maximum...

Hives ferment a yeasty brew, attract beetle pest

...e small hive beetle is a minor honeybee pest, bees quickly isolate an invading beetle, but domesticated European honeybees are not as diligent in cleaning their hives. The beetles are also aided in their invasion by a yeast that naturally occurs on pollen and produces, as a fermentation product, the alarm ch...
