Worms produce surprise insight into human fever

...er the best of both worlds, says Aballay. He also points out that new drugs designed to activate HSF-1 are already in clinical trials for treating neurodegenerative diseases. “Our work opens the possibility of using co-inducers of HSF-1 to boost immunity to treat infectious diseases and immunodeficienci...

Research suggests beta agonists may alter the immune system

...ese findings occur in the human body, our research points to an important means by which the immune system is regulated by both therapies and the hormonal system," Penn said. "From an asthma management standpoint, these studies further emphasize the need to include anti-inflammatory corticosteroids when tre...

Scientists discover role for dueling RNAs

...nd," says Fink, senior author on the paper. "This points to an entirely new process of gene regulation that we've never seen before in eukaryotic cells." There is a method to this sense/antisense madness, one that has a kind of yin and yang quality. When conditions around yeast cells are good and ric...

Exposure to dioxins influences male reproductive system, study of Vietnam veterans concludes

...ffects in the veterans in the study." The study points out the necessity to conduct additional environmental studies of the impact of dioxins and other toxins on the male reproductive system. Previous research was largely based on animal models, Dr. Gupta said, noting that the urgency of further research...

HIV exploits competition among T-cells

...rs against a particular disease ?act as collection points for different parts of the body. Moreover, because it takes 4-5 days for T cells produced in a lymph node to begin to leave it, the possibility exists to set up simultaneous, independent competition against each of the multiple strains that will evol...

PNAS study reveals why organs fail following massive trauma

...tem is actually two systems developed at different points in human evolution. White blood cells of the more primitive innate system, like neutrophils and macrophages, form the first line of defense against disease. They swarm to the injury to engulf and destroy bacteria with toxic molecules and biochemical...

Emotional control circuit of brain's fear response discovered

... in fear response, we decided to explore the finer points of the neurocircuitry of fear ?how it is regulated/controlled in the brain." To accomplish the tricky task of studying fear in the brain, she turned to a method described in the Dec. 2005 Nature Neuroscience. In a paper featured on the cover of th...

Sunflower speciation highlights roles for transposable elements in evolution

... multiplying and inserting themselves at different points throughout a host genome. They are found in virtually all eukaryotic genomes. The new findings not only add an interesting twist to the origin of new sunflower species through hybridization, but also suggest that the sunflower system may emerge a...

Plutonium or greenhouse gases? Weighing the energy options

... as your problem? I don't have the answer, but the points I'm raising are ones I think people need to be considering." ...

A reason why video games are hard to give up

... of games and game environments were studied, Ryan points out that "not all video games are created equal" in their ability to satisfy basic psychological needs. "But those that do may be the best at keeping players coming back."...

Gene therapy study takes aim at prostate cancer

...r near the site of the tumor as well as in distant points in the body. "We hope that by generating a systemic immune response, we are enabling the body to destroy prostate cancer cells that have moved elsewhere," he said. Kadmon and his colleagues plan to test six different doses of the gene. The gene ...

When nerve cells can't make contact

...ally altered mice without neuroligins, the contact points at which the nerve cells communicate, the synapses, do not mature. The researchers assume that similar malfunctions are experienced by autistic patients. Autism is one of the most common psychiatric illnesses. Around 0.5 percent of all young child...

Solved: The mystery of flesh-eating bacteria's relentless attack

...xplains why it is so virulent." He said the work points to more effective strategies for treating Streptococcus infection. "There are different avenues you could explore for treatment, all based on reducing the amount of ScpC the bacteria produces," Hanski said. "You could look for a specific inhibitor of...

Mobile DNA part of evolution's toolbox

...en you activate a gene in a new context," Bejerano points out, "you get processes that did not occur before." Bejerano and Haussler's results support the hypothesis that the movement of retroposons can generate evolutionary experiments by adding new regulatory modules to genes. Most of these experiments w...

Hair samples show babies can be exposed to 'crystal meth' while in the womb

...etus are not fully known, but the evidence to date points to restricted fetal growth and developmental problems. Crystal meth users were also significantly more likely to use other drugs, the results showed. Most (85%) of the 396 samples positive for crystal meth also tested positive for at least one ot...

Fire ants: Their true story told by the scientist who loves them

...," he said. As for the much-maligned fire ant, he points to what he calls a 50-year-old misconception about shrinking native ant populations. Turns out it's not the competition with fire ants, as many believe, but rather the ecological havoc created by disturbed habitats ?fire ants thrive in them, natives ...

Female guppies risk their lives to avoid too much male attention

...protect species and habitats," explains Croft, who points out that fish are not the only species who display this social characteristic. "In many ecosystems, predators are the first to go extinct, and our work shows that this may have many, perhaps unexpected, effects. In this case, females may suffer more ...

New research: Soy germ isoflavones reduce bone loss

...on in postmenopausal women. This research strongly points to soy isoflavone supplementation as a natural, effective way to significantly improve the quality of life for postmenopausal women. ...

Infected for life

... new study, published online last month in Nature, points to a small RNA molecule, called a microRNA (miRNA) as the culprit that keeps the latent virus-infected cell alive. These findings could one day lead to a new way to fight the virus and offers the first target for intervention in the latent infection....

Ten years later, Dolly is still making headlines

...hest issues ?and exposing our members to disparate points of view so they ?as the most highly trained scientists in the world ?can draw their own conclusions," said John Lisack, AAPS executive director. "With topics like cloning and biogenerics headlining this year's event, there is no more exciting and cha...
