New U. of Colorado at Boulder flu chip may help combat future epidemics, pandemics

... occur in avian flu H5N1, which has been spreading rapidly from bird to bird in Asia, Russia and parts of Eur...both avian and human flu types, we could detect it rapidly using this technology," Kuchta said. Standard laboratory culturing techniques by the CDC and WHO cu...

New evidence supports century-old theory of cancer spread

...le compared to unfused melanoma cells. They spread rapidly when implanted in mice. Even though the idea is virtually unknown to cancer researchers today, many scientists worked on it in the 20th century. From the late 1960's up to today there have been many reports of tumor hybrids." "Aichel implored future...

Targeted drug delivery achieved with nanoparticle-aptamer bioconjugates

...cancer cells and confirmed that the particles were rapidly internalised into the targeted cells ?an important fact since the payload of nanoparticles may be released inside the cancer cells in a regulated manner over an extended period of time. The study principle investigator Dr Omid Farokhzad from Harvar...

Researchers use 'trickery' to create immune response against melanoma

Poison + water = hydrogen. New microbial genome shows how

...rs discovered why C. hydrogenoformans grows more rapidly on carbon monoxide than other species: The bug boasts at least five different forms of a protein machine, dubbed carbon monoxide deyhydrogenase, that is able to manipulate the poisonous gas. Each form of the machine appears to allow the organism to ...

Picking particles faster than one at a time

... of biological molecules from electron microgaphs, rapidly and automatically, with accuracy approaching that of experienced human analysts. The new algorithm, described as "particle picking by segmentation," promises to greatly increase the speed and power of methods for determining biological structures a...

Bird song changes sound alarm over habitat fragmentation

...enic environmental deterioration. Because of their rapidly evolving cultural nature, bird vocalisations might become an early warning system detecting the effects of fragmentation over relatively short times and before other indicators - such as genetic markers - show any change," they say. Sharing song typ...

Contagious obesity? Identifying the human adenoviruses that may make us fat

... lack of exercise weren't the only culprits in the rapidly widening human girth. Since then, Ad-36 has been found to be more prevalent in obese humans. In the current study, Whigham et al. attempted to determine which adenoviruses (in addition to Ad-36 and Ad-5) might be associated with obesity in chickens....

Clawed frog helps Fanconi anemia research make leaps

...s of the cell cycle. The bulk of the cells are not rapidly dividing, and it's only when cells are dividing that the Fanconi proteins are usually at their highest expression and activity." In Xenopus eggs, however, Fanconi proteins are stockpiled in preparation for the rapid divisions that occur after fertil...

New evidence questions the simple link between prion proteins and madcow disease

...how it was taken up. They saw the abnormal PrP was rapidly taken up by finger-like projections called villi and passed in to the lymph. It was not, however, taken up by structures called Peyer's nodules, that are believed to be the places where animals amplify the infective agent. "The fact the PrP isn't ta...

Largest study of human 'interactome' reveals a novel way

...genetic disorders offers a novel approach for more rapidly identifying new candidate genes involved in human diseases," he says. The analysis included interactions among 1,077 genes coding for proteins linked to 3,133 diseases, the researchers report. Significantly, it showed that proteins encoded by gene...

Technique makes it easier to see mouse embryo in all its glory

...rchers' ability to study the mouse embryo and more rapidly focus on abnormalities of development, including childhood cancers. Birth defects are diagnosed in 150,000 babies in the U.S. annually. Suspected causes are genetic abnormalities, environmental insults, and drug and chemical exposures. Charles Kell...

Wisconsin scientists discover a master key to microbes' pathogenic lifestyles

..., warmer environment. And as soon as they do, they rapidly shift gears and assume the guise of pathogenic yeast, causing such serious and sometimes deadly afflictions as blastomycosis and histoplasmosis. But how these usually bucolic fungi undergo such a transformation to become serious pathogens has always...

Cortex matures faster in youth with highest IQ

...eir brain's outer mantle, or cortex, thickens more rapidly during childhood, reaching its peak later than in their peers ?perhaps reflecting a longer developmental window for high-level thinking circuitry. It also thins faster during the late teens, likely due to the withering of unused neural connections as...

Rochester scientists develop fast-working biosensor

... demonstrated a new technology that accurately and rapidly detects the meat-spoiling and sometimes dangerous E. coli bacteria. The unique technology uses a protein from the suspect bacteria as part of the sensing system that also includes a silicon chip and a digital camera. The journal Biosensors and Bioe...

Intelligently designed molecular evolution

...evolved, and with our methodology, we were able to rapidly and efficiently evolve it down a pathway of our choice," Keasling said. "We are recapitulating evolution into intelligent design. In the case of this particular Grand fir enzyme synthase, it naturally makes a soup of small amounts of 52 different p...

Powerful new tool for studying brain development

...ene that is expressed during brain development can rapidly determine how it fits into the overall scheme of brain development," said Craig Brumwell, PhD, the GENSAT manager in St. Jude Developmental Neurobiology. "The BGEM helps researchers skip over much of the drudgery of digging up information from the li...

New drug could reduce tissue damage after heart attack

...or. "We now propose to develop a CRP inhibitor as rapidly as possible for testing in patients with heart attacks. "The drug would be given as soon as patients arrived in hospital. If effective, it would reduce the amount of damage in the heart, thus limiting both early mortality and the size of the scar l...
