Ebola-outbreak kills 5000 gorillas

...e door to targeted vaccination strategies that, by breaking the chain of transmission, could be much more efficient than in the case of outbreaks driven entirely by reservoir spillover. The consistent spread rate of the Ebola infection wave also suggests that vaccination could be targeted just ahead of the ad...

Scientists find new way to manipulate DNA

...bulence. "This paper understands how they are breaking in a new way that resolves some issues that have been present for 40 years," Solomon said. The experiments that yielded the prevailing scission theories, Solomon said, did not take into account turbulence in the flow that occurred during the exper...

New engineered drug may offer prolonged arthritis relief

...tens the activity of enzymes that damage joints by breaking down their collagen "framework," Setton explained. She credits team member Virginia Kraus, professor of rheumatology and immunology at Duke University Medical Center, for focusing on IL-1 as a major mediator of osteoarthritis in the joint. Given th...

Two central mysteries in genome inheritance solved at UCSD

... by detecting errors in attachment to the spindle, breaking down these defective attachments and starting over. But until now, scientists did not understand how cells detected such an error. Sharsti Sandall, a graduate student in the Biomedical Sciences Program at UCSD, identified a complex of two protein...

Two-faced protein can stop metastasis or promote it, researchers say

...glue that holds cells together also is involved in breaking them apart and promoting their movement when tumors begin to spread to other parts of the body, researchers at Mayo Clinic have found. The study, published in the Sept. 18 online issue of the Journal of Cell Biology, helps illuminate the very first ...

Biofuel cells without the bio cells

... commercially viable but they offer the promise of breaking down sewage and other biological waste while generating electricity directly from the same process. An example, Squier said, is a self-powering sewage treatment plant. Using pure protein opens up the possibility of shrinking biofuel cells to power ...

A simple feedback resistor switch keeps latent HIV from awakening

...t of transcription but quickly disappeared without breaking viral latency. This prediction of the model was then precisely replicated in cell culture experiments. An array of cell culture experiments perturbing the supposed Tat resistor was then performed. For example, inhibition of the deacetylating enzyme S...

Eat less, weigh more? Enzyme makes lean mice 'susceptible' to dietary fat

...dy is starved, the body literally feeds on itself, breaking down fat to form fatty acids that fuel energy needs. When the cells of the body are well fed and energy is in ample supply, molecular signals from the brain tell cells in the body to store the excess energy by converting it to fat. Weight gain resul...

DOE publishes research roadmap for developing cleaner fuels

...rces and talent to support the President's goal of breaking our addiction to oil, while also enhancing our energy security." ...

A sweet solution for Alzheimer's disease?

...ol--has been shown previously to be ineffective at breaking up amyloid aggregates, he said. In the brain of a person with Alzheimer's disease, small proteins called amyloid â aggregate into plaques, and a protein called tau clumps into neurofibrillary tangles. The brain becomes inflamed and neurons atrophy a...

South Pacific plant may be missing link in evolution of flowering plants

...available both online and in print, the Journal is breaking new ground by being the first in the sector to be printed on 100 percent post-consumer waste recycled paper, as is appropriate for a publication dedicated to promoting environmental best practice. As David Butler says, 'Our goal is to build on the ...

Mitochondrial DNA sequencing tool updated

...nded molecule. By gathering mitochondrial DNA and breaking it into short, single-stranded bits, the scientists showed that each bit would pair, or hybridize, with its complementary sequence arrayed on the chip. By crude analogy, each bit is like a unique magnet that sticks to its mirror image. But if the...

Tiny shock absorbers help bacteria stick around inside the body

...ired to keep the finger trap-like FimH anchor from breaking loose. "This system is similar to a set of shock absorbers on your car that dampen turbulent forces caused by bumpy road conditions," added study co-author Dr. Wendy Thomas, assistant professor of bioengineering at the UW. The researchers found th...

Hopkins researchers discover genetic switch that turns off an oxygen-poor cell's combustion engine

...: glycolysis, which makes modest amounts of ATP by breaking down the glucose without using oxygen; and the TCA cycle in the mitochondrion, which normally uses oxygen to produce large amounts of ATP by processing a byproduct of glycolysis. The disruption of this link blocks the tendency of the mitochondrion ...

'Shuttling' protein possibly key to resilience of cancer cells

...uorescence complementation. The procedure involves breaking a fluorescent protein into two fragments and then fusing each fragment to different AP-1 proteins, including c-Jun and ATF2. When the proteins later bind to form a heterodimer, the fluorescent-protein fragments are reunited, causing them to glow gree...

Does father know best?

... Anderson also organized the data geographically, breaking down nonpaternity rates in different countries according to high and low paternity confidence. Among those for who paternity confidence was relatively high, actual nonpaternity is highest in Mexico and lowest among the Kohanim lineages of Sephardic J...

Scientists develop a way to make the deadliest toxin known even more toxic

...teases are enzymes that act as cellular catalysts, breaking up proteins into smaller elements such as amino acids and reducing the amount of energy needed for the activation. The study was released in an advanced online version by the Journal of the American Chemical Society. Kim Janda, currently the Ely ...

Researchers test new way to quit smoking

...early use of nicotine replacements might assist in breaking the cigarette habit, according to Dr Bullen. "Nicotine is a highly addictive substance. It has been proposed that the stress a person undergoes when giving up cigarettes, coupled with the burden of remembering to use alternative methods of nicotine ...

Protein 'nanosprings' most resilient found in nature

...d forces, the team found. When extended past their breaking points, the molecules exhibited a saw-tooth pattern of regularly spaced force peaks as individual repeats unraveled one by one, they said. After this complete unfolding of the protein, the researchers observed that ankyrin repeats were able to rapid...
