Would an Antimatter Magnet Attract a Normal Matter Magnet?

Eye (c)  Giulia Ciappa from Firenze

Why do you see flashes and patterns when you press your eyeballs? Would an antimatter magnet attract normal matter magnets? What is the hardest human bone to break? We take on your science questions this week, as well as explore the bed of Lake Windermere the gravity hills of Barbados and the first discovered habitable exoplanet.  Plus, a flapless aircraft takes flight, how the brain decides which hands to use and why Raman spectroscopy offers a rum deal for anti-drug squads. In Kitchen Science, we find out why spit can form strings of beads...

  • 01:46 - Flapless Aircraft takes to the air

    Ever since the Wright brothers first took to the air in 1908 aircraft have been controlled by moving surfaces in order to deflect air in different ways, in a conventional plane, elevators, aerolons etc. Now BAE systems have flown the first flapless aircraft...

  • 04:13 - Hand preference arises from a competition in the brain

    Researchers writing in the journal PNAS this week have come a little bit closer to understanding how the brain chooses which hand to use for any particular action. They think it comes down to a mental competition between the hands....

  • 06:30 - A new Earth-like exoplanet

    This week, astronomers at the University of California, Santa Cruz and also from the Carnegie Institution of Washington have announced the discovery of an Earth-like planet thatís outside our own solar system. Itís thought that liquid water, as well as an atmosphere, could exis...

  • 12:36 - Double current in solar cells

    The best way of making solar electricity cheaper is to get more electricity per square metre of panel. Now researchers at Colorado State University and University of Wyoming solar energy laboratory may have found ways to convert far more of the incipient solar energy into electr...

  • 18:37 - What causes the bright patterns when you rub your closed eyes?

    If I am in a dark room and I rub my closed eyes, why does it appear that I see bright lights or vivid color patterns? I have been enjoying your podcasts for a couple of years.† My commute to work is always educational (and fun) with the Naked Scientists on board.† Thanks for a...

  • 20:40 - From where do magnets obtain their "energy" ?

    Why dont magnets ever "run out of power" to attract or repel?† ferromagnets in specific, i understand why electric current magnets keep working as long as there is a current, but alignment in ferromagnets dont use current, so why do they keep working...isnt this a contradiction t...

  • 25:37 - What keeps the brain in place after a hemispherectomy?

    Hello, Chris and company, love the show. I've read that the human brain has a very gelatin-like consistency. I also heard you talking last week about people who have had a hemisphere of their brain removed. This makes me wonder how they keep the rest of their brain from oozing al...

  • 28:30 - Would an anti-matter magnet attract iron?

    Assuming it was possible to create a magnet made of anti-matter,†would it attract or repel anti-matter iron / normal Iron? Would you have anti-magnetism or is magnetism the same in an antimatter universe as it is here if so why?

  • 29:51 - How do fish gills work?

    How do fish metabolize oxygen? Specifically, how does the fish's gill extract oxygen from the H2O molecule?

  • 31:34 - Planet Earth Online - Surveying Lake Windermere

    Over the past few weeks, scientists have been carrying out the first geological survey since the 1930s of Englandís largest lake - Lake Windermere in Cumbria. Richard Hollingham has been along to find out whatís been found...
