...idea came to mind. Because openings into joints can let bacteria in, I had kept Manuel on oral antibiotics. But I recalled an experiment done with lab mice bred in a sterile environment. Without any bacteria around they couldn't heal cuts in their skin. Maybe my antibiotics were suppressing some bacteria that were needed to coax these knee wounds to heal. So I stopped the antibiotics and brought Manuel back a week later. No dice - still no change...
Undergraduate scientists put aside their lab coats on Saturday afternoon, donning suits and black “got research?” T-shirts as they mingled in the Science Center atrium for the Harvard Undergraduate Research Symposium. The symposium, organized by members of the newly formed Harvard College Undergraduate Research Association, provided a venue for students to present and discuss the scientific research they had performed. “We want to give undergraduates the chance to be the ones answering questions instead of asking questions,” said Shiv M. Gaglani ’10, the group?...
...Soviet master-spy Alexander Feklisov, the cold-war operative who ran some of the KGB's deadliest spies in the West. Feklisov's recruits included Julius Rosenberg, widely believed to have provided information on the Manhattan Project, and German scientist Klaus Fuchs, who had worked at the Los Alamos lab. Feklisov was pivotal in his country's acquisition of the nuclear bomb, first exploded in 1949, some five years before U.S. agents expected...
...this year, Atala's group became the first to make another valuable discovery: that amniotic fluid contains stem cells. These have proven critical in helping his team to regenerate tissues from the more ornery cells of the pancreas, liver and nerves, which don't grow as well in a lab dish. Amniotic-fluid stem cells aren't as versatile as embryonic stem cells, which can turn into every tissue type in the body, but they can still develop into an impressive number of much-needed cell types, and Atala has already used them to grow up muscle, bone...
...patients to receive Atala's regenerated organs were seven young children who were transplanted with bladders grown from their own cells. Eight years after their surgery, the children are doing well, and their bladders continue to function normally. Atala now has about 20 other tissues and organs in his lab almost ready for human trials, but he refuses to rush the technology. "Our goal is to transfer these technologies from bench to bedside in the fastest way possible," he says, "But we have gone slowly in these trials because we wanted to make sure that the tissues and organs...
