Chronic Sinus Infection Thought To Be Tissue Issue, Mayo Clinic Scientists Show It's Snot

...D. "Instead we found that these toxic proteins are released into the mucus, and not in the tissue. Therefore, scientists might need to take not only the tissue but also the mucus into account when trying to understand what causes chronic sinus infections and probably other airway diseases." The findings coul...

Major new UNC-based drinking water study suggests pregnancy fears may be overstated

...rofessor and chair of epidemiology, and colleagues released a report on the investigation today (July 29).

Survey reveals women and doctors aren't talking about HPV

...n papillomavirus (HPV) - according to a new survey released by the Association of Reproductive Health Professionals (ARHP). HPV is extremely common, affecting an estimated 80 percent of sexually active adults in their lifetime, in some cases staying dormant until years after the initial infection. Yet few are...

Study of energy and health in Africa focuses spotlight on charcoal and forest management

...ns, they said, with over 15 billion tons of carbon released into the atmosphere by 2050. "Most charcoal is produced in Africa by one or two guys going out in the woods, almost always without a permit and on somebody else's land, cutting down a tree or two, chopping it up, lighting it, covering it with dirt, ...

Scientists discover global pattern of big fish diversity in open oceans

A new study released in Science (via Science Express http://www.sciencexpress.org) on July 28th reveals a striking downward trend in the diversity of fish in the open ocean ?the largest and least known part of our planet. Teasing apart the effects of climate change and f...

It's electric: Cows show promise as powerplants

... a new idea : some farmers already use the methane released by livestock waste to power machinery and lights. But converting methane into electricity requires costly equipment : one California farmer reportedly spent $280,000 to convert his operation to a methane digester system. "Methane still needs to unde...

Scientists reveal how disease bacterium survives inside immune system cell

...al infections. A paper describing the research was released today online in The Journal of Immunology. Frank R. DeLeo, Ph.D., of Rocky Mountain Laboratories (RML), part of the National Institute of Allergy and Infectious Diseases (NIAID) of the National Institutes of Health, directed the work at RML, in Hamil...

Scientists discover the body's marijuana-like compounds are crucial for stress-induced pain relief

...stood the conditions in which these compounds were released to block pain. Researchers along the way found out there are two kinds of stress-induced analgesia mechanisms, opioid and nonopioid (or "opioid independent"). Hohmann and colleagues discovered that the opioid-independent form was produced by release...

Scientists discover that three molecules may be developed into new Alzheimer's drugs

...e July issue of the journal Chemistry and Biology, released on Friday, July 22. As baby boomers grow older, the incidence of Alzheimer's, already increasing, will rise much more. "Our approaches to the disease are flagrantly inadequate," said Kosik. "There are a couple of FDA-approved drugs that help a litt...

Insects develop resistance to engineered crops

...istant to a single Bt toxin. The insects were then released into caged growing areas with either single-gene plants, dual-gene plants or mixed populations and allowed to reproduce for two years. The researchers found that after 26 generations of the insect living in the greenhouse with single-gene and dual-g...

VCU study shows hormone-like molecule kills cells that cause inflammation in allergic disease

...ine, heparin and a number of cytokines are rapidly released into the tissues and blood, promoting an allergic reaction. Mast cells are believed to be generated by different precursor cells in the bone marrow. In the in vitro portion of the study, researchers used mouse bone marrow cells containing the stem...

...originating from the same gene in all bacteria, is released outside the cell to announce the cell's presence. Nearby bacteria take a local census by monitoring AI-2 levels and conduct themselves as the circumstances warrant. Researchers have speculated that AI-2 is a universal language, and the new study fro...

Carnegie Mellon University research reveals how cells process large genes

Scientists show that tick-borne flaviviruses use a novel mechanism to evade host defenses

...or under the skin or in various organs. The study released this week online in the Journal of Virology describes how a single virus protein--NS5--from the tick-borne Langat flavivirus counteracts the natural ability of interferon to combat the virus. Langat virus was originally isolated in the 1950s in Malay...
