For many insects, winter survival is in the genes

...andful of other insects suggests that they have an arsenal of protective heat-shock proteins that are turned on almost as soon as the temperature dips. Until this new study, researchers knew of only two such proteins that were activated in flesh flies during cooler weather. "Insects need heat-shock protei...

Newborn neurons like to hang with the 'in' crowd

...he existing circuitry. With the help of a whole arsenal of high-tech imaging technology and the electron tomography expertise of Mark. H. Ellisman, Ph.D., a professor at the National Center for Microscopy and Imaging Research at the University of California, San Diego, Toni then zoomed in at a nanometer s...

Nanotechnology shows promise as next wrinkle fighter

...ology such as electronic monitors. The cosmetic arsenal to fight human wrinkles embraces technologies that seems crossed with science fiction ?from microdermabrasians to lasers to Botox injections ? and nanoparticles are poised to join the war by warding off dreaded buckles in human skin. Ilsoon Lee, a...

Ultrathin films deliver DNA as possible gene therapy tool

...g conventional materials," Lynn explains. A bigger arsenal of tools may allow researchers to tailor films for specific applications. In addition to delivering DNA from stents, Lynn envisions using these nanoscale films to deliver DNA from other implantable devices. The films may also improve methods for en...

Selecting life: Scientists find new way to search for origin of life

... interest with the DNA microarray and ToF-SIMS, an arsenal of other techniques can be used to look at the details of the interactions. "What's particularly rewarding about this research is that it's an interdisciplinary effort from different areas of science--biology, chemistry and geology," reflected Ha...

Molecular 'signature' protects cells from viruses

Every cell constantly produces a whole arsenal of proteins. The instruction what is to be built comes from the cell nucleus: this is where the DNA is stored, the heredity molecule in which, so to speak, the construction blueprints for all cellular proteins are stored. If a particular protein is t...

A new understanding of how cells defend themselves against bacterial pore-forming toxins

...pore-forming toxins are a key weapon in the attack arsenal of some common and virulent bacteria, such as Staphylococcus aureus, well-known for its role in hospital-acquired infections, Streptococcus pneumonie, responsible for middle ear infections and pneumonia, and Helicobacter pylori, implicated in ulcers...

Most widely used organic pesticide requires help to kill

... and environmentally friendly weapons in the human arsenal against insect pests has significant implications not only for the control of insects in agriculture, forestry and human health, but for understanding microbial disease in humans and other animals. "The take-home message is that we've shown that th...

AIDS drug from sunflowers

...otential. 'We need these substances to expand our arsenal of effective weapons against the disease,' Dr. Esther Vogt of the Immunological Out-Patient Service of Bonn University Clinic adds. 'It remains to be seen, however, whether they will prove to be as effective in clinical practice as they seem to be at...

Study in Science holds promise for a new approach to drug therapy

...r the hotspot," Smrcka said. "Taken together, this arsenal would grant us precise control over one of the most important biochemical switches in the body. This area of study is so important because of the sheer number of drugs already on the market that could be made more effective by differential targeting....

Mice studies illustrate potential of chimp/human antibodies to protect against smallpox

...o existing vaccines that we can use to enhance our arsenal of medical countermeasures." Using a library of antibodies derived from the bone marrow of two vaccinia-immunized chimpanzees, the study researchers identified a pair of potent antibodies that target and neutralize the B5 protein, one of five key pr...

Discovering the first steps in transcription-coupled repair

...he production of altered proteins, cells deploy an arsenal of repair mechanisms to excise and replace defective nucleotides, reconnect broken strands, and patch up other kinds of damage. Transcription-coupled repair is unique: it targets repair to genes that are actively being transcribed into messenger RNA...

Moffitt-USF head toward first human trials of anti-cancer drug that targets protein AKT

...i-cancer drug that could add another weapon in the arsenal against several cancers, including tumors of the breast, ovary, colon, skin and prostate. The compound, tricirbine, was tested at various cancer centers from 1982 to 1996 and found to inhibit some cancers, but researchers failed to determine why. Th...

Venom doc tracks down snake bioweapons

... recruited and altered proteins for their chemical arsenal from other body tissues. This enabled snakes to develop more specific, highly potent toxins, ones that would cause their victims' bodies to turn against themselves upon injection. Over time, these newly derived toxins became a normal part of the sali...

Secret of smallpox's success may lead to bioterror cure

...gerous viruses as well, making available a who new arsenal of weapons against disease. Antigen-eliciting genes from hard-to-treat viruses such as HIV could potentially be added to the mutant vaccinia virus, which would draw the immune system's attention to the target virus's proteins, thus creating a strong ...

Researchers uncover sequence of major rice pathogen

...ganism's weaknesses. You do that by building up an arsenal of information of what genes are involved in plant-pathogen interactions," Dean says. In July 2002, Dean and researchers from the Whitehead Institute at MIT, now called the Broad Institute, issued a preliminary genome sequence of M. grisea, and made...

Key Trigger Of Opioid Withdrawal Symptoms Found

...and jumpiness. Such drugs could become part of the arsenal of medicines and behavioral techniques aimed at helping addicts kick their habits. To zero in on the machinery underlying withdrawal symptoms, researchers led by Elena Bagley and Macdonald Christie of the Pain Management Research Institute at Royal...

Controversial drug shown to act on brain protein to cut alcohol use
