A new study has found that stem cells grown from patients' own cardiac tissue can heal damage once thought to be permanent after a heart attack. Experts say the experimental approach may one day help stave off heart failure.
In other biomedical news, high levels of arsenic in some prepared foods has been traced to an organic brown rice syrup used as a sweetener and main ingredient, including some cereal bars and infant formulas. According to the study, one of the two infant formulas tested had arsenic concentrations up to six times the federal safe drinking water limit.
