  • 00:20 - Building a Biological Pacemaker

    Normal heart cells can be converted into specialised pacemaker cells using gene therapy, and this could pave the way to building a biological pacemaker, according to research published in the journal Nature Biotechnology...

  • 02:54 - 7000 Year Old Cheese

    This week, scientists have uncovered residues of 7,000-year-old cheese. Chemist Professor Richard Evershed from the University of Bristol is one of the authors of a paper in the journal Nature this week which describes how he and his team have made this rather milky discovery.....
