  • Do crabs feel pain?

    Crabs, and other crustaceans, may feel pain and learn from painful experiences

  • Landsat 8 launch

    Landsat 8 to be launched next month, continuing over 40 years of Earth observation

  • Looking for dark matter

    Should the Fermi telescope concentrate on looking for elusive dark matter in our Universe?

  • Crabs feel pain

    Professor Bob Elwood
    You cannot ask an animal if they feel pain.  Most people accept that higher animals, the vertebrates, feel pain in the same way as we do.  We all recognise when our cat or dog is hurt.  But what about invertebrates, like crustaceans, such as crabs, prawns or lobsters?  There has been a long belief that they only show a flinch reflex, or nociceptive response, to a painful stimulus.  But new research adds weight to the argument that crustaceans do feel pain like we do, because they can learn to avoid future painful experiences after being given an electric shock.

  • Landsat 8 Launch

    NASA's Earth Observation satellites have been monitoring land use changes on our home planet for over 40 years.  Beaming back images to a resolution of 30 metres, the Landsat satellites have shown the growth of cities, deforestation and even climate change effects over this time. The eighth satellite is about to be launched early next month and is eagerly awaited by scientists all over the world, not least because the incredibly useful information is free.

  • Looking for dark matter

    Fermi 3-year all-sky map
    Another Earth orbiting NASA satellite is in the news this week. This one looks out into space.  It houses the Fermi telescope, which has been scanning the whole cosmos since 2008, catching sight of the highest-energy light we know of - gamma rays.  These come from the most energetic and exotic corners of the Universe: supernova leftovers, the flashing neutron stars called pulsars, even the jets from black holes.  But this week, there's more hope that the Fermi telescope might be able to pin down one of the biggest mysteries in astrophysics: the mysterious stuff called dark matter.
