The CHAVI investigators wanted to study those patients who had many sequential blood samples taken during this plateau in viral load. Before their analyses began collaborators in the EuroChavi consortium, coordi...

Researchers discover inherited mutation for leukemia

... also may provide new insights into the process of natural cell death. They may even lead to new strategies for treating the disease. The research is to be published in the June 1 issue of the journal Cell. It was led by researchers at the Ohio State University Comprehensive Cancer Center. The mutati...

Agent slows aging in mice

Math that powers spam filters used to understand how brain learns to move our muscles

...ays the artificial brain in the computer, like its natural counterpart, is guided in part by a special kind of statistical “probability” theory called Bayesian math. Unlike conventional statistical analysis, a Bayesian probability is a subjective “opinion,” that measures a “learner’s” individual degree o...

Bigger horns equal better genes

... theory of ageing, which is the idea that, because natural selection weakens with age, genetic mutations have effects that accumulate over time. Therefore, differences in genetic quality become more apparent as an organism ages. Coltman noted that his study, which incorporated genetic samples from more t...

How to lose weight and not go hungry: HU researcher develops drug that mimics feeling of 'fullness'

...lly in order to curb his appetite, thus leading to natural weight loss. In experiments with mice, it was shown that a single oral administration of BL-3020 led to reduced consumption over a period of 24 hours. Over a 12-day period of daily dosages, the mice weighed 40 percent less than the average for mice o...

Dirty snow may warm Arctic as much as greenhouse gases

...ls to the ground. Soot-infused snow is darker than natural snow. Dark surfaces absorb sunlight and cause warming, while bright surfaces reflect heat back into space and cause cooling. “When we inject dirty particles into the atmosphere and they fall onto snow, the net effect is we warm the polar latitudes...

Loss of stem cells correlates with premature aging in animal study

...grity of their DNA, and multiple divisions lead to natural breaks in DNA. But when these stem cells are needed, their progeny can rapidly divide and are able to replenish the tissue with new cells. Brown explains that in the current study the mouse cells without ATR had an overwhelming amount of DNA dama...

Bacteria ferry nanoparticles into cells for early diagnosis, treatment

...a could be used as vehicles, harnessing bacteria's natural ability to penetrate cells and their nuclei, Bashir said. "For gene therapy, a big obstacle has been finding ways to transport the therapeutic DNA molecule through the nuclear membrane and into the nucleus," he said. "Only when it is in the nucleu...
