A team of Virginia Tech researchers has succeeded in transforming cellulose into starch, a process that has the potential to provide a previously untapped nutrient source from plants not traditionally thought of as food crops.
There's an epic battle taking place that's not on the national radar: intercellular competition. While it's not an Olympic event, new research from UC Santa Barbara demonstrates that this microscopic rivalry can be just as fierce as humans going for the gold.
Scientists at Washington University School of Medicine in St. Louis have shown they can coax cells to move toward a beam of light. The feat is a first step toward manipulating cells to control insulin secretion or heart rate using light.
Scientists investigated the effects of introducing a novel artificial neural connection which bridged a spinal cord lesion in a paretic monkey. This allowed the monkey to electrically stimulate the spinal cord through volitionally controlled brain activity and thereby to restore volitional control of the paretic hand.
Researchers at the University of North Carolina at Chapel Hill School of Medicine have 'rationally rewired' some of the cell's smallest components to create proteins that can be switched on or off by command. These 'protein switches' can be used to interrogate the inner workings of each cell, helping scientists uncover the molecular mechanisms of human health and disease.
Scientists have revealed a new technique to introduce disease-blocking bacteria into mosquitoes, with promising results that may halt the spread of diseases such as dengue, yellow fever and potentially malaria.
The accomplishment provides a much-needed resource for scientists eager to uncover the true mechanisms of human stem cell biology. It also enables them to explore new tactics to treat inflammatory bowel disease or to ameliorate the side effects of chemotherapy and radiation, which often damage the gut.
One of the major obstacles to growing new organs _ replacement hearts, lungs and kidneys _ is the difficulty researchers face in building blood vessels that keep the tissues alive, but new findings from the University of Michigan could help overcome this roadblock.
