Rearing an army to save wheat

...now, we have to locate a large population of these beneficial insects before we can redistribute them. If we can reliably have them available at a known location, we could do our job much more efficiently."...

Studies find general mechanism of cellular aging

...hat these not entirely benign things were having a beneficial effect? Now we have a biomarker that can directly test the effects of such things," he said....

BC catalyst discovery promises faster, cheaper drug production

...e hand, or enantiomer, of the drug molecule can be beneficial to a patient's health, while the other may be harmful. Because of this, it is important for anyone who wants to prepare drugs, especially in large quantities, to be able to synthesize single-handed compounds with high selectivity; ideally, none of ...

Novel vaccine shows promise against early-stage breast cancer

... these specific genetic variances may be extremely beneficial in preventing breast cancer for many women. In this study, researchers investigated a potential vaccine that targets HER-2/neu over-expression in early stage breast cancer, known as DCIS (ductal carcinomas in situ, or early stage cancer formation...

Drug can quickly mobilize an army of cells to repair injury

... to tissues. "Like AMD3100, G-CSF can bring these beneficial cells from the bone marrow into the bloodstream, but with G-CSF you don't see an increase in angiogenic cells until the fourth day," says senior author Daniel C. Link, M.D., associate professor of medicine in the Division of Oncology. "In a patient w...

Geneticists discover genes that make fruit fly hybrids sterile

...two different species -- may offer interesting and beneficial traits, they are usually sterile or unable to survive. For example, a mule, the result of the mating of a horse and a donkey, is sterile. Now, Cornell researchers have made the first identification of a pair of genes in any species that are responsi...

Researchers discover that sheep need retroviruses for reproduction

... of Glasgow Veterinary School. "This infection was beneficial to the host and was then positively selected for during evolution. In other words, animals with enJSRVs were better equipped than those without. Therefore, enJSRVs became a permanent part of the sheep genome and, in these days, sheep can't do without...

Worms produce surprise insight into human fever

...nity provides both a molecular explanation for the beneficial role of behavioral fevers in poikilotherms and a mechanism by which fever works in metazoans, says Aballay. It also raises questions about the HSF-1 pathway in humans and whether drugs currently used to reduce fever in infected patients may mak...

Does natural selection drive the evolution of cancer?

...tion. Can we push it down paths that might be more beneficial to us?" One idea might be to develop new drugs ...tion in which two organisms interact in a mutually beneficial way. Tumor cells send signals to stimulate the growth of the cells that form the scaffold in which t...

Patients can report statins' adverse effects on new web site

...t to understand the full spectrum of effects, both beneficial and adverse," said Golomb. "Our work is geared toward expanding knowledge of the impact of statins in order to better inform the public and the medical community. By filling out the web site survey, statin patients can help us to help others with t...

Therapeutic role found for carbon monoxide

Chemotherapy temporarily affects the structures of the human brain

...evelopment of chemotherapy has had substantial and beneficial impact on cancer survival rates, it is also linked to significant short- and long-term adverse effects. Gastrointestinal complaints, immunosuppression, and painful mucositis, for example, are the immediate risks of the treatment. Patients receivi...

New neurons could act to alleviate epilepsy

...he newly generated neurons "could have significant beneficial effect on the epileptic syndrome," concluded the researchers. "Our study demonstrates that both a physiological stimulus and an insult to the adult brain trigger the formation of new dentate granule cells, which are functionally integrated into hi...

A new jump start for aging blood vessels

...o date, no studies have investigated the potential beneficial effects of TNFa inhibition in vascular aging, making this the first study of its kind. Csiszar and collegues treated aged rats with etanercept to test the hypothesis that anti-TNFa treatment exerts vasculoprotective effects in aging. Etanercept...

Biotech cotton provides same yield with fewer pesticides

...de-containing crops like Bt cotton would also kill beneficial and non-target arthropods. The new study found that Bt cotton, also known as transgenic cotton, does not affect the biodiversity of insects in cotton fields. Carrière said, "There were lots of factors that affected biodiversity in this study. Tr...

Gene transfer using mutant form of good cholesterol cuts vascular plaque and inflammation

...apo A-I gene. Therefore, we concluded, the greater beneficial effect of A-I Milano gene transfer is most likely related to a greater efficiency of A-I Milano in promoting the removal of cholesterol from the macrophages."

The obser...

Beaver dams create healthy downstream ecosystems

Beavers, long known for their beneficial effects on the environment near their dams, are also critical to maintaining healthy ecosystems downstream. Researchers have found that ponds created by beaver dams raised downstream groundwater levels in the Colorado River valley, keeping soil water...
