Live vaccines more effective against horse herpes virus

...ted, a horse carries the virus for the rest of its life in a "latent" (dormant) state. The same symptoms from the initial infection can be reactivated by stress later in life. Osterrieder will present his new findings on vaccine effectiveness, involving a limited study of 15 horses, at a luncheon meeting...

Cooperation is key—a new way of looking at MicroRNA and how it controls gene expression

...from the normal processes that govern the everyday life of human cells to the aberrant mechanisms that underlie many diseases, including cancer and septic shock. The discovery concerns tiny fragments of RNA known as microRNA and their relationship to the genetic transcripts known as messenger RNA (mRNA)....

Shutting down the HIV assembly line

...assembly process is just one part of the whole HIV life cycle," Spearman noted, "but it's an important part in that each step along the way is required to make an infectious viral particle." Spearman's team has focused on a protein called "Gag," the major HIV structural protein. In recent years, Spearman...

Researchers discover underwater volcano

...bial aggregations that are produced by microscopic life feeding on chemical energy from the volcano's hydrothermal system. As Staudigel and his international team explored the area, they discovered a number of large communities of eels inhabiting the fragile cavernous rock pillars surrounding the hydrothe...

Researchers find promising cancer-fighting power of synthetic cell-signaling molecule

...therapeutic drugs using funds from EmTech Bio -- a life sciences technology business incubator operated by Georgia Tech and Emory. This research is coordinated with Slainte Bioceuticals, a start-up biotechnology company in metro Atlanta that is helping to bring this potential drug to market. "Even if Eni...

At long last, scientists figure out how plants grow

...inding, the scientists can now envision a complete life history for the growth hormone. Auxin is produced in the tips of plant shoots and branches. The hormone travels downward toward the roots. It migrates into plant cell nuclei, where it is picked up by the TIR1 portion of a four-protein complex called ...

Africa to take it on chin again with climate change

...xtreme," says Hurrell. Monsoon rains, critical to life in much of Africa, shift north and south with the seasons. They normally reach the Sahel from July to September and the southern part of the continent from February into April. Low-pressure centers moving west from the Sahel during the monsoon often ...

MUHC scientists describe genetic resistance to rampant virus

...f human therapies for CMV, which could prolong the life of HIV patients and improve the success of transplant surgery by reducing the risk of rejection. There is currently no treatment or cure for CMV. Resistance to diseases like CMV depends, at least partially, on the ability of our body's defense mecha...

Friendly bacteria in humans may protect against HIV

... Beneficial Microbes Conference. "I believe every life form has its natural enemy, and HIV should not be the exception," says Dr. Lin Tao, Associate Professor of the Department of Oral Biology, College of Dentistry, University of Illinois at Chicago. "If we can find its natural enemy, we can control the ...

Oceans more vulnerable to agricultural runoff than previously thought, study finds

...These algal blooms are natural events that benefit life in the gulf by generating tons of phytoplankton-a major source of food for larger organisms. But some phytoplankton species produce harmful blooms, known as red or brown tides, which release toxins in the water that can poison mollusks and fish. Exc...

Doctors closer to using gene analysis to help trauma patients

... a decision that could mean the difference between life and death, according to UF Genetics Institute scientists. “The vast majority of patients who experience severe trauma or burn injuries actually do well,?said Lyle Moldawer, a surgery professor in UF’s College of Medicine. “They’re resuscitated at th...

Confocal imaging promises early detection of skin cancer

...d for 50 years, but only recently been used in the life sciences area. Because it calls on lasers and high-end imaging, confocal technology is expensive. One project goal was to reduce the manufacture costs ?by stripping away everything not needed for skin diagnosis, redesigning optical components and pr...

Study reveals candidate targets for anti-retroviral therapeutics

...oteins encoded by Ty elements and the steps of the life cycle in yeast are similar to the proteins encoded by retroviruses and their life cycles in animal cells. Scientists believe that these simple elements in a single-celled organism ar...

Low oxygen likely made Great Dying worse, greatly delayed recovery

... Earth's history, killing 90 percent of all marine life and nearly three-quarters of land plants and animals. Ward said paleontologists had previously assumed that Pangea was not just a supercontinent but also a "superhighway" on which species would have encountered few roadblocks while moving from one p...
