Researchers discover key mechanism by which lethal viruses Ebola and Marburg cause disease

...SEB Journal. "The Columbia study has shown us new ways to fight against deadly viruses the world over." The method for discovering this protein underscores the power of bioinformatics for addressing the challenges of emerging infectious diseases. The investigators are currently exploring whether insig...

Newly discovered behavior in cancer cells signals dangerous metastasis

... switch might ultimately enable scientists to find ways to stop cells from metastasizing, which is the most deadly trait of cancer," said the study's lead investigator, Mariano Garcia-Blanco, M.D., Ph.D., professor of molecular genetics and microbiology. The researchers will publish their findings in the...

Soil nutrition affects carbon sequestration in forests

...t how much forests can sequester, we need accurate ways to predict what happens to carbon within forest systems and how this partitioning is affected by environmental conditions."...

New mechanism underlying pain found

... present an opportunity for the development of new ways to treat the severe pain associated with such common conditions or diseases as sciatica, diabetic neuropathy and shingles. This research was presented at Neuroscience 2006, the annual meeting of the Society for Neuroscience. Neuropathic pain, o...

World's smallest cancer detection device

...t with surrounding tissues, cells and chemicals in ways that all too often encourage cancer cells to invade other areas of the body in the process known as metastasis. With the new NCI grant, Dr. John Condeelis, co-chair of anatomy and structural biology at Einstein and the principal investigator of the...

Patients can report statins' adverse effects on new web site

...on statin use, including what users can expect and ways in which they can minimize health risks. Golomb has been actively researching the effects of statin medications for the past seven years. She and the research team at UCSD School of Medicine are currently completing an NIH-funded study of 1,000 su...

New moth variety disarms plants guarded by selenium

...ings potentially have implications for a number of ways in which selenium accumulation might be utilized in different ecological and agricultural circumstances. Applying selenium to plants may be an efficient way to deter herbivory and improve crop productivity, and if managed carefully, the supplied sele...

How ants find their way

...h gives us the opportunity to learn more about the ways that animals, including humans, process information to learn, reason, make decisions and communicate. BBSRC is working with other Research Councils and funders to support new interdisciplinary research in this area." ...

Stem cell activity deciphered in the aging brain

... Hattiangady said. The team now is searching for ways to stimulate the brain to replace its own cells in order to improve learning and memory function in the elderly. One approach being explored is to treat older rats with drugs designed to mimic the action of compounds called neurogenic factors, whic...

Brains can recover from alcoholic damage but patients should stop drinking as soon as possible

... capabilities for re-growth. Our findings show the ways that the brain can recover from the toxic insults of chronic alcoholism and substantiate the early measurable benefits of therapeutic sobriety. However, they also suggest that prolonged dependence on alcohol may limit rapid recovery from white matter...

Dragonfly's metabolic disease provides clues about human obesity

...an species suffering from metabolic dysfunction in ways similar to humans. "Metabolic disease isn't some strange thing having just to do with humans," said Marden. "Animals in general suffer from these symptoms." The work is also novel because it links metabolic disease to a supposedly harmless paras...

Researchers find docking sites for glucocorticoid receptor and Hsp90

...rmones. The discovery, they say, could lead to new ways to boost the effectiveness and reduce undesired side effects of steroid-hormone treatments and cancer drugs. The study, published online this week ahead of regular publication in the Proceedings of the National Academy of Sciences, also uncorks an...

Intrinsic eye protein halts angiogenesis

...eviously, scientists had experimented with various ways to clear blood vessel growth in corneal tissue ?a condition that often occurs due to herpetic infections of the eye, chemical burns, traumatic injury or surgery such as corneal transplantation. "The standard paradigm has been the cornea is avascula...

Search on for treatment of slow-healing wounds

...ofilm Engineering a $2.9 million grant to find new ways to heal chronic wounds. The money will allow the center to fund undergraduate research, hire more doctoral-level researchers and purchase equipment for its investigation into the role biofilms play in chronic wounds. The money will be distributed o...

Age-related changes in DNA repair illuminate the connection between age and genetic damage

...lism and environmental influences--and the various ways in which cells repair that damage. In the new work, researchers found that cells in young fruit flies make use of a different mix of molecular DNA-repair mechanisms compared to cells in older flies. The findings are reported by William Engels and col...

Restoring tamoxifen sensitivity in resistant breast cancer cells

...nts," said Farrar. His laboratory is now exploring ways to produce DIBA in a form that is water soluble so it could be administered as a pill, the same as tamoxifen. If successful, this could set the stage for preclinical studies. ...

Different strategies underlie the ecology of microbial invasions

...y, researchers have compared two different general ways in which bacteria compete with one another, and they have found that each strategy seems to be particularly effective under different ecological circumstances--for example, depending on whether the bacteria are rare invaders or abundant residents. Th...

St. Jude finds clues to hearing loss from chemotherapy

...cific mutation disrupts that cascade might lead to ways to repair the damage, Zuo said. For example, one type of damage that occurs in children whose hearing is damaged by chemotherapy is loss of hair cells in the inner part of the ear. These cells sprout extremely fine hairs that move in response to sou...
