Credit: A. Goldman et al., Science Translational Medicine Two medical problems caused by misfiring electrical signals, epilepsy and heart arrhythmia, probably have a common molecular cause, scientists report. The research points to treatments that could lower the chances of young people dying of seizures. The scientists, at Baylor College of Medicine in Houston, Texas, were studying mice that had a mutation in the KCNQ gene, which builds potassium ion channels...
