  • 00:23 - The First Lumberjacks

    Scientists at Tel Aviv University have discovered and analysed some remarkable stone age tools that they say are the first evidence of humans felling trees to clear agricultural land, and to use wood as a building material.

  • 03:18 - Dark matter close to home

    A paper published in the Monthly Notices of the Royal Astronomical Society this week reports a detection of dark matter in the vicinity of our own Sun.

  • 08:23 - Artifical protein scaffold props up heart repair

    Using short, self-assembling bio-degradable protein nanofibres impregnated with a blood-vessel growth factor, scientists have been able to prevent some of the negative changes that occur in the heart following a heart attack and boost cardiac recovery...

  • 12:43 - Knocking epilepsy on the head, electrically

    Electrical brain stimulation triggered by the impending onset of a seizure could be used to prevent epileptic attacks, scientists have shown.
