Genetic clues found for common congenital brain disorder

of the genes involved and have a mouse model to study to figure this out." This work may also have broader implications. Understanding what goes wrong in Dandy-Walker malformation could provide clues about autism, in which similar but much milder ...
U of T study identifies possible stem cells in pancreas
...hemselves over the entire life of the organism and some
ability for the parent cell to generate varied cell types for example islet cells and exocrine cells. Pancreatic stem cells could provide a plentiful supply of beta cells for transplant treatments. A finding Smukler considers equally exciting is the...
Why damaged DNA gets a case of the bends

enzymes bend damaged DNA in order to repair altered fragments. But no one knew why damaged DNA was more susceptible to bending." Haranczyk and colleagues' simulation, reported Sunday at the American Chemical Society national meeting, offers an explan...
Clemson University spin-off uses corn to make plastics, provide cleaner air
...id is a byproduct of corn. It currently is used in some
pill coatings and sutures because it easily dissolves -- a property not desirable in drink containers, boat coatings and packaging. Clemson University professor Dennis Smith and his research group have found a new way to replace up to 50 percent of ...

blood cancers. The main function of the D cyclins is a linking one. They respond to signals outside the cell and turn the cell-cycle machinery on when needed, enabling the cell to adjust to changes in environment. How this process is carried out in t...
Heartless worms hold clues to cardiac arrhythmias, sudden death

individuals receiving a HERG-blocking drug develop the syndrome, Petersen said. "It's a serious problem," she said. "The FDA now requires that every drug be assayed for HERG block before it is approved." Even medicines that might be beneficial for th...
