Newly-discovered class of genes determines ?and restricts ?stem cell fate

...ell what it should become and restrict its fate by preventing differentiation. The ability of a single biochemical factor or complex of factors to have this dual role may represent a new general paradigm for developmental and stem-cell biology. "My idea is that this is a new family of genes--they can both deter...

NYU Study Reveals How Brain's Immune System Fights Viral Encephalitis

... in neurons fight the virus at multiple stages--by preventing the formation of viral RNA and proteins, and blocking the virus' release, which could infect other cells in the brain. "There is no magic bullet in fighting viral infections in neurons," said NYU Biology Professor Carol Shoshkes Reiss, the study's s...

Antibiotic Resistant Bacterium Uses Sonar-like Strategy to “See?Enemies or Prey

According to Gilmore, “These bacteriaare actively probing their environment for enemies or food. Based onwhether or not they ‘see?other cells, they make the toxinappropriat...

Why do insects stop 'breathing'? To avoid damage from too much oxygen, say researchers

...stems periodically to keep out excess oxygen, thus preventing damage to their tissues. Timothy Bradley, professor of ecology and evolutionary biology at UCI, and Stefan Hetz, assistant professor of physiology at Humboldt University, Germany, report their findings in the Feb. 3 issue of Nature.

Duke Chemists Isolating Individual Molecules Of Toxic Protein In Alzheimer's, Parkinson's Disease

...erstanding, they said, could lead to approaches to preventing plaque formation. The researchers led by Boris Akhremitchev are using the infinitesimal tip of a customized atomic force microscope (AFM) to capture, isolate and study single molecules, called monomers, that are the building blocks of the toxic prot...

Newly Discovered Compound Blocks Known Cancer-Causing Protein

"By preventing Icmt from adding a methyl group, we can effectively shut down Ras' ability to function, stopping it from sending signals for uncontrolled growth." Initial experiments showed that knocking out the Icmt protein using genetic targeting also inhibited R...

Implanted Devices Detect High-Risk Heart Failure Patients

...cs). Implantable devices are the latest options in preventing arrhythmias that can lead to sudden death, with CRT-Ds being the latest technology. CRT-Ds perform two main functions. First, the devices electrically stimulate both sides of the heart in coordinated fashion, which optimizes the contractability of a...

New Insights Into HIV Immunity Suggest Alternative Approach to Vaccines

The researchers say that the fly research translates to humans even more than they thought it would. "Humans have the same kind of genes and potassium channels. And we know that slow waves must be generated by c...
