Scientists grow heart muscle strip in mice
Harvard Stem Cell Institute and Mass General researchers used mouse embryonic stem cells to create a ventricle muscle strip seeded on a scaffold. The strip beat spontaneously in the lab, marking progress toward regenerating heart tissue. Further work must produce thicker tissue with blood supply and durable beating.

Acetaminophen May Weaken Baby Vaccine Effects
Czech researchers report in Lancet that giving acetaminophen with vaccines in 459 infants aged 9 to 16 weeks reduced fever but also reduced protective antibody levels after both primary and booster shots. About 90 percent still developed antibodies, and postvaccination acetaminophen had no effect if fever had already appeared. An accompanying editorial notes small overall risk.
