Renewed dolphin slaughter prompts new campaign

...d the Association of Zoos and Aquariums (AZA). The immediate goals of the campaign are to raise public awareness of the dolphin drive hunts , to boost measurable support through the group's website petition ( www.actfordolphins.com ) which currently includes over 22,000 signatures, and to convince the Japanese...

Chemotherapy temporarily affects the structures of the human brain

...ssion, and painful mucositis, for example, are the immediate risks of the treatment. Patients receiving chemotherapy have also long complained of problems with memory, problem-solving and other cognitive abilities. Although chemotherapy was thought not to affect brain cells due to the blood-brain barrier, ...

UNC scientists solve mystery of how largest cellular motor protein powers movement

...hat,?Doholyan said. While the research offers no immediate application to human disease, the authors noted that mutations of dynein have been implicated in some neurodegenerative and kidney disorders. Dokholyan pointed out that disruption of dynein’s interaction with a particular regulator protein causes def...

Most widely used organic pesticide requires help to kill

...ins unknown. The upshot of the new work may have immediate application in designing strategies to manage insect pests by enhancing the killing effects of BT using indigenous insect gut microbes or other bacteria known to promote blood poisoning. "The work also raises the possibility that the genes encoding...

Pure carbon nanotubes pass first in vivo test

...o the bloodstream of research lab animals cause no immediate adverse health effects and circulate for more than one hour before they are removed by the liver. The findings are from the first in vivo animal study of chemically unmodified carbon nanotubes, a revolutionary nanomaterial that many researchers hope...

Mother birds give a nutritional leg up to chicks with unattractive fathers

...[and] present a high risk of death, a focus on the immediate reproductive attempts may be the only viable strategy," write the researchers. "By depositing antioxidants in a compensatory manner, females can maximize the reproductive output from the current nesting effort." ...

Genetic 'roadmap' charts links between drugs and human disease

...e and in separate publications in the September 28 immediate early edition of Cancer Cell. The three papers show the map's ability to accurately predict the molecular actions of novel therapeutic compounds and to suggest ways that existing drugs can be newly applied to treat diseases such as cancer. Based on t...

Leptin found to control appetite and limb development in frogs

...age with little fat reserves. They pay the cost of immediate survival by being more prone to drying out, to being eaten by predators and reaching sexual maturity at a later age. Denver speculates that leptin is probably important to gauge whether the tadpole has adequate energy reserves---in the form of body f...

Researchers appeal for new regulations to save coral reefs from live fish trade

...ld's reefs have been effectively destroyed with no immediate prospects of recovery, 24% are under imminent risk of collapse and 26% are under longer term threat of collapse. The scientists argue in their letters that multilevel action, from local to international, is needed to establish institutions that are...

With few factors, adult cells take on character of embryonic stem cells

...lls. The researchers reported their findings in an immediate early publication of the journal Cell. The cells--which the researchers designate "induced pluripotent stem cells" (iPS)--exhibit the physical, growth, and genetic characteristics typical of embryonic stem cells, they reported. "Pluripotent" refers...

Study details hepatitis C ability to block immune system response

...Viral infections like hepatitis C often trigger an immediate innate immune response involving release of type 1 interferon (IFN-? and IFN-?). In turn, type 1 interferon stimulates the production of a family of what are known as IFN stimulated genes that have a multitude of inhibitory effects on viral replicati...

Bacteria can help predict ocean change

.... Each one has its own place." The findings have immediate relevance for scientists attempting to understand how the oceans are changing, Fuhrman said. If bacteria behave predictably, they can be used to improve models for ocean change. By including bacteria, which make up the vast majority of species on l...

A new tool against brain disease

... The researchers' discoveries could lead to immediate clinical application, although Walker cautioned against over-optimism. "Obviously, the big question is whether you could manipulate this pathway in HIV-infected people to turn these T cells back on and better control the virus," he said. "And drugs t...

How HIV 'exhausts' killer T cells

... The researchers' discoveries could lead to immediate clinical application, although Walker cautioned against over-optimism. "Obviously, the big question is whether you could manipulate this pathway in HIV-infected people to turn these T cells back on and better control the virus," he said. "And drugs t...

Scientists aim to thwart use of flu as bioweapon

... is already a killer, the discussions will have an immediate application among scientists looking for ways to stop or better treat "natural" flu. The work also helps scientists like John Treanor, M.D., and David Topham, Ph.D., who are designing and testing new vaccines designed to prevent all types of flu, inc...

Stanford snake venom study shows that certain cells may eliminate poison

Death by snakebite is horrible. The immediate pain of the bite is followed by swelling, bruising and weakness, then sweating or chills, with numbness, nausea, blurred vision and possibly convulsions before it's all over. Such misery is produced by a veritable witches' brew of toxins in snake ven...

Bacteria beat the heat

...perature of the bacterial habitat, rather than the immediate conditions. This may protect the cells from harmful swings in enzyme activity. We can envision using this knowledge, for instance, to facilitate enzymatic reactions in different applications, enhance crop production in areas subject to extreme temper...

Drug triggers body's mechanism to reverse aging effect on memory process

...e the connection between nerve cells, which has an immediate effect of boosting LTP. But they also increase the presence of this important protein, BDNF, that can stay in the body and keep boosting memory after the drug has worn off." ...
