'Juiced-up' battery fueled by sugar could power small portable electronics
...ntly, scientists only recently have learned how to unleash the energy-dense power of sugar to produce electricity, Minteer says. A few other researchers also have developed fuel cell batteries that run on sugar, but Minteer claims that her version is the longest-lasting and most powerful of its type to dat...New test predicts blood cancer's sensitivity to experimental cancer drug
...ble to a promising type of experimental drugs that unleash pent-up "cell suicide" factors to destroy the cancer. The researchers demonstrated that chronic lymphocytic leukemia, CLL, which is diagnosed in 10,000 Americans each year, is an easy mark for the new drug because the cancerous cells are strongly d...News tips from the Journal of Neuroscience

This week, Bauer and Patterson tested the effects of leukemia inhibitory factor (LIF), a cytokine that increases stem cells survival in vitro . Using viral vectors, they overexpressed the gene e...... the initial protein-DNA binding interactions that unleash the flow of information which, in turn, sparks gene expression. "We can use the ruler to look at this process much more upstream. We can measure the beginning stages of DNA-binding activities," says Fanqing Frank Chen, a scientist in Berkeley Lab'......alone, while the latter has within it the means to unleash the dazzling cascade of events needed to create a viable organism. What's already in the egg that enables it to make the transition? How is it the same and how is it different across species? And what changes occur when the egg is fertilized?

..., viruses or parasites attack, immune system cells unleash the soldiers. These "hot" protein compounds kill invaders but also trigger inflammation, which, if unchecked, can destroy tissue, induce shock and kill the host. So immune system cells let loose another protein compound to cool down the immune respo......prowl for potentially dangerous invaders, ready to unleash their deadly arsenal at a moment's notice.
