Scientists find method to pick noncompetitive animals, improve production

...ool makes it possible to design selective breeding programs to effectively reduce competitive interactions in livestock, he said. The method also aids in predicting how social interactions impact the natural evolution of species. Muir and his colleagues write about the tool and its effectiveness in two pap...

Darwin's famous finches and Venter's marine microbes

...sequence. Based on overlapping sequences, computer programs can then assemble longer stretches and merge them into longer pieces of a genome. These so-called "scaffolds" are a treasure trove for a diverse group of scientists, who try to squeeze as much information as possible from the largest metagenomic data...

Rewarding fat rats

...ngoing research has already produced some computer programs and robots that can learn from experience and adapt their behaviour to a complex, constantly changing environment. We can expect that this technology will be greatly improved in the near future." ...

Resistance to anti-HIV drugs in Uganda developed due to drug supply problems

... of greatest need. "Notwithstanding the current programs providing free antiretrovirals, these findings do highlight the need for strong logistics and drug supply management in any antiretroviral therapy program as well as continued monitoring of adherence. While our patients did a great job of taking thei...

Pacific Rim researchers to collaborate on distributed bioinformatics analysis of avian flu

..., grid-enabled software tools and student exchange programs that have emerged out of PRAGMA." Pacific Rim institutions collaborate in PRAGMA to develop grid-enabled applications and coordinate deployment of the needed infrastructure throughout the Pacific region to allow data, computing, and other resource...

Army research mission focused on autism

...hat one day soon we will have successful treatment programs for all children with autism and the knowledge to prevent it from ever happening in the first place," Redwood said....

HIV dementia alarmingly high in Africa

...e-limited countries like Uganda and encourage more programs that bring much-needed medication to these poor regions of the world," Sacktor says. Sacktor says there’s little accurate data about HIV dementia patients in other parts of the world --- current estimates of the number of HIV-positive patients wh...

Virginia Tech's System X supercomputer provides super tool for simulation of cell division

...by the global algorithm." The parallel computer programs can now be used by others for similar problems. "The parameters found for the budding yeast cell cycle model are good until the next scientist invalidates them with new experimental data. That could be years from now or next week. That's the way scie...

Chronic pain up almost 40 percent among US workers in past decade

... of employers surveyed now offer worksite wellness programs to employees, compared to 40 percent in 1996. But while the number of wellness programs is relatively high, the number of programs addressing chronic pain is not. Only 22 percent of wellne...

NASA satellite data helps assess the health of Florida's coral reef

...f the world's coral reefs have been destroyed, but programs like the Florida Reef Resilience Program bring scientists, reef managers and the community together to develop strategies that improve the health of reefs while enhancing the economies dependent on their success. Continued monitoring of coral reefs...

How mammals fuel milk production may have implications for cancer

...se. To accomplish this, two distinct developmental programs must be executed: first, cells must proliferate and differentiate to form the structures that will ultimately serve as the site of milk synthesis, the researchers said. Second, mammary epithelial cells must coordinately activate multiple biosynthetic...

The subtleties of tropical forest demise

...se of tropical ecosystems. He has active research programs in the Amazon and Central Africa. Carlos Peres is a Reader in tropical ecology and conservation at the University of East Anglia, U.K. He is a recipient of a Bay Foundation ‘Biodiversity Conservation Leadership Award', and was previously elected an...

To slow AIDS in Russia, treat HIV-positive addicts, Stanford study says

...y, said Owens. One key to implementing treatment programs will be keeping injection drug users on their HIV medications, said Owens. Antiretroviral therapy regimens have become much simpler, often requiring patients to take just one or two pills per day. "If they can get the treatment and support, intr...

Train your brain to hear your friends at a party

...hey could be helped by computer generated training programs which run like regular computer games, but can target weaknesses in listening skills. By incorporating training exercises much like those performed by the ferrets, they can lead to auditory learning and an improved ability to listen." ...

A new approach to growing heart muscle

...ardiovascular structures in the laboratory. Active programs include tissue engineering models for cardiac muscle, tri-leaflet valves, cell-based cardiac pumps and vascular grafts. In addition, the laboratory has expertise in several different tissue engineering platforms: self-organization strategies, biodegr...

Computer scientists unravel 'language of surgery'

...permitted to be in the hospital, surgical training programs need to streamline their training methods now more than ever. This research work represents a strong effort toward this." Hager's other collaborators include Sanjeev Khudanpur, a Johns Hopkins assistant professor of electrical and computer engineer...

Knockout Mouse Project

...n 30 million DNA samples that are used in research programs around the world. The research institute's DNA library has become a major resource for ongoing global research in the genetics of human diseases. The recombinant DNA library is, for example, being used in Oakland to investigate the genetic differenc...

HIV/AIDS linked to extensively drug resistant TB

... danger of blunting or reversing the success of TB programs and the roll-out of anti-retroviral therapies for HIV where they are desperately needed in resource limited settings. Urgent intervention is necessary, especially now that we know that MDR tuberculosis is far more prevalent than previously thought an...

Did 'ABCs' cause Uganda's fall in HIV rates?

...ause of its focus on abstinence-only sex education programs over condom promotion, a focus that pits political and religious conservatives against their liberal counterparts. Nevertheless, the ABC approach is sometimes credited as being responsible for Uganda's dramatic decline in HIV rates. A provocative d...

Successful lung cancer surgery not enough to break nicotine dependence in many smokers

...as possible after treatment," Walker said. No such programs are currently offered to lung cancer surgery patients, he added. At least seven studies of non-small cell lung cancer patients have shown that many of these patients continue smoking despite the risk, but the rate of relapse ranged from a low of 1...
