Now, self-healing materials can mimic human skin, healing again and again

...more healing agent into the network, ‘scar tissue’ builds up in the coating and prevents the healing agent from reaching the catalyst.” In the current system, the healing process stops after seven healing cycles. This limitation might be overcome by implementing a new microvascular design based on dual ne...

Human stem cell treatment restores motor function in paralyzed rats

...onal mobility of the patient’s legs. This study builds on Marsala’s previous work in rat models using human neuronal stem cells, published in October 2004 in the European Journal of Neurosciences. In that study, significantly improved motor function, measured by a suppression of spastic movements and i...

Puzzling plankton yield secrets to role in evolution/global photosynthesis

...an adaptive process in Ostreococcus. "This work builds on the community’s emerging understanding about how carbon fixation is carried out by picoplankton," said Brian Palenik, lead author and researcher at the Scripps Institution of Oceanography, University of California, San Diego. "From an applied p...

Switching genes to overdrive improves muscular dystrophy symptoms in mice

...bers to contract. Part of the reason that exercise builds stronger muscles is that it increases PGC-1alpha activity. Conversely, disease or lack of exercise reduces PGC-1alpha activity, causing a loss of NMJ function and weakening, or atrophying, of muscles. Spiegelman’s team had previously bred a strain...

Bones in motion: Brown scientists to create new 3-D X-ray system

... complete system available by 2010. The project builds on orthopedic imaging work at Henry Ford Hospital in Detroit and on original research in skeletal imaging at Brown, including a trailblazing technique developed by Gatesy that uses animation software to combine CT scanner data with X-ray images. Imag...

Overfishing large sharks impacts entire marine ecosystem, shrinks shellfish supply

...Hill and co-leader of the study. The research builds upon an earlier study by Myers and Baum, published in Science in 2003, which used data from commercial fisheries to show rapid declines in the great sharks of the northwest Atlantic since the mid-1980s. Now, by examining a dozen different research su...

But this approach ultimately generates materials with high overall levels of copper -- levels that are too costly to remove...

From a lowly yeast, researchers divine a clue to human disease

...ymerase II "reads through" the end of the gene and builds longer and longer RNA messages. "In some cases it doesn't have a big effect," Brow says. "Other times, it's a big problem," like when another important gene is right next-door on the same piece of DNA. Like run-on sentences, long RNAs from multip...

Dr Baum's research builds on his earlier work when, in collaboration with others, he completed a full study of the function of every one of the fruit fly's genes in cells. This is allowing him now to compare those to similar genes in human cell lines to help him understand wh...
