Genomic Analysis Uncovers New Targets for HIV Vaccine

... an infection. One of the genes looks particularly attractive as a vaccine target. The study, published early online by the journal Science July 19, was directed by David Goldstein,Ph.D., at Duke University and is the first large cooperative study with major findings arising from the Center for HIV/AIDS Vaccin...

ASU research shows connection between testosterone, dietary antioxidants and bird coloration

...sts of testosterone elevation and still keep their attractive and bright colors,” McGraw said. Most previous studies of this sort have focused on physiological or even genetic links between testosterone and health. He adds that it is worth considering the implications for human nutrition and health. “If test...

Researchers demonstrate way to control tree height

...es can also affect foliage shapes or color in very attractive ways, and some might have value in cleaning up environmental pollution. In their studies, OSU scientists were able to create young poplar trees, which grow rapidly and can reach a mature height of 150 feet or more, that were anywhere from about 15...

Veterinary scientists explore poultry virus as cancer killer

...esigned to have specific properties that make them attractive as biotechnological tools, live vaccines, and cancer therapeutics. This is achieved through the introduction of the desired changes in the cDNA, which are then transferred faithfully to the recombinant virus. In the current investigation, Subbiah...

Why aren't humans furry? Stone-Age moms could be the answer

...uenced whether the mother kept or abandoned it. An attractive baby was more likely to be kept and reared. Har...Age people believed that hairless babies were more attractive than hairy ones, this could explain why humans are the only apes lacking a coat of fur. Harris sugge...

New biofuels process promises to meet all US transportation needs

...internal combustion engine technology. It is quite attractive for hybrid electric vehicles and plug-in hybrid electric vehicles." To grow enough biomass for the entire nation's transportation needs using the conventional method for producing biofuels would require a land area 25 percent to 55 percent the siz...

Producing medicines in plant seeds

...he desired protein. Plant seeds are especially attractive as production units. In addition to a high production capacity, they offer other important advantages over other parts of the plant. The seeds can be stored for a long time without losing the produced protein's effectiveness, so that a reserve can al...

Protein found to shield pancreatic cancer cells from self-destruction

.... This pathway, Mehta explained, could make TG2 an attractive target for other forms of cancer as well. ...

Scientists uncover new target in cancer mutation puzzle

...or the p53 gene. Someday Rho may prove to be an attractive target for therapy because it is highly active only in malignant cells and not in normal cells. "Now that we understand more about the role of Rho proteins as a target of cooperating cancer gene mutations in tumors with p53 mutations, we will look...

Viral protein is an effective preventative against infection

...eveloping secondary ear infections and would be an attractive alternative to traditional antibiotics, to which bacteria are rapidly becoming resistant. The bacteria that cause middle ear infections, Streptococcus pneumoniae, aren’t transmitted at school. They already reside on the mucosal membranes in the no...

Baby fish 'smell their way home'

...in size. "We tested several ideas, but the most attractive seemed to be that they could smell the unique trace of their home reef ?rather like salmon can smell the home river. "We know these late stage fish larvae, generally between about 9 and 14mm long, already have developed noses ?but the question was...

Ultrathin films deliver DNA as possible gene therapy tool

... polymers carry a positive electric charge that is attractive to DNA, each polymer layer also "primes" the surface to accept the next layer of DNA. While electrostatic forces between the layers keep the film stable in dry, room-temperature conditions, the polymers break down easily in a wet biological environm...

Florida Tech explores microalgae for biofuel

...vironmental concerns. Microalgae cultivation is an attractive alternative and the warm Florida climate makes large-scale production a possibility," said Lin. ...

Human preference for other species could determine whether they survive

...ublic lands, some homeowners continue to plant the attractive vine in their yards, where it can spread to the wild. "We do have these big differences in how we feel about living things," Stokes said. "These feelings are going to play a big role in what we choose to conserve."...

Virus may control Australia's

...d eventually killing its host. Koi herpesvirus is attractive as a biological control agent as overseas studies suggest that it has a very limited host range, infecting only carp. "If the laboratory studies show promise, the next step will be extensive government, public and industry consultation to determine ...

Study illuminates how the plague bacteria causes disease

...we might identify the pathogen's Achilles heel--an attractive target for antibacterial or anti-virulence compounds." "We were quite excited to see such a critical and unexpected factor in the virulence of Yersinia--a bacteria historically responsible for some of the worst diseases," he added. Although improve...

New sunscreen ingredient to heal sunburn and help prevent skin cancer

...f research, the team has designed two commercially attractive prototypes which are currently in laboratory trials. The prototypes contain 'caged' iron binding sites which release the chelators only in response to high doses of UV light, thus avoiding toxicity to cells. The new sunscreens containing these c...
