Heart

Heart disease is the leading cause of death in many parts of the world, including the U.S., England and Canada, so it's not surprising that bioengineers at Duke University are excited by what they believe could be an important first step toward growing a living “heart patch” to repair damaged heart tissue. In a series of experiments using mouse embryonic stem cells, the bioengineers used a novel mold of their own design to fashion a three-dimensional "patch" made up of heart muscle cells, known as cardiomyocytes. The new tissue exhibited the two most important attributes of heart muscle cells - the ability to contract and to conduct electrical impulses. Read More

Finally, video-gamers whose parents told them that playing games would never help them get a job can point to research that proves them wrong – well, sort of, anyway. A new study by a University of Warwick researcher has demonstrated that scientists trying to model a range of processes could ‘borrow’ an Xbox chip to get all the power and capabilities they need, saving thousands of dollars on parallel processing hardware and/or countless man-hours.
