What Happens to a Tankful of Fish in Orbit?

Trout (c) Trout Lore

Why are there two high tides a day when there's only one moon? Would a planet made of glass be transparent? Does dreaming about exercise burn more calories? And what would happen to a tankful of fish launched into Earth's orbit? To find out, and to hear how the solar cells of the future can keep themselves clean, how researchers have uncovered a new way to combat cancer and how astronomers have spotted showers of meteors hitting Jupiter, join Drs Chris, Dominic and Dave as they blast off into a new series of the Naked Scientists in pursuit of the ultimate answers to your wildest and wackiest questions...

  • 01:49 - Self cleaning solar cells

    A new high voltage way to clean your solar cells with less water and elbow grease involved.

  • 03:30 - A breath of fresh air in climate change debate

    A new model of future greenhouse gas emissions suggests that it's not too late to reverse predicted climate change trends. In fact, the new study shows that the main greenhouse gas threats to Earth's future climate have yet to be built.

  • 06:37 - Asteroids in the outer Solar System

    A paper published this week in the Astrophysical Journal presents the first direct observations of small asteroids in the outer solar system.

  • 09:50 - RNA-away cancer cells

    A molecular magic bullet could hold the key to selectively deleting cancer cells from the body, a new study has shown.

  • 13:19 - Variable fundamental constants

    Some evidence has been found of the fine structure constant... varying.

  • 17:21 - Music, Emotion, and Pain Control

    Also in the news this week, EPSRC funded researchers up in Glasgow have been investigating how we respond emotionally to music, and how this could lead to music being used in pain control. Sarah Castor-Perry caught up with the researchers involved to find out more ...

  • 22:03 - How does the moon cause two tides every day?

    As I understand it, the moon, when itís directly overhead, causes the oceans to rise and thatís giving us our high tide. We experience that twice every 24 hours, but the moon is only overhead once every 24 hours at the same spot. What causes the second high tide?

  • 23:43 - How fast is a bird flying inside a moving bus?

    If a bus is travelling at 100 miles per hour [mph], and you are at the back of the bus holding a bird, and then it is let go and it flies towards the front of the bus, how fast is the bird flying?

  • 30:45 - Can a goldfish swim in outer space?

    If I took my fish in its bowl into orbit abroad the International Space Station? Now, assuming that the fish does actually survive the journey up there and it doesnít get upset and all that kind of thing with the water coming out.. what would be the implications, in terms of phy...

  • 32:39 - How do bats know it is night time?

    How do bats know it is night time?

  • 35:02 - Marine Renewable Energy

    Increasingly, governments and energy companies are looking at ways of harvesting wave and tidal energy. But what about the environmental impacts of marine-based renewable energy technologies? Richard Hollingham finds out more...

  • 40:02 - Does running in a dream burn calories?

    If you dream that you're running, you wake up tired. Is that because your brain believes that you were actually running? And do you burn calories?

  • Fungal enzyme gives yeast green energy boost

    Green fuels, like bioethanol, produced by yeast fermentation of plant sugars can be used to cut greenhouse gas emissions. Unfortunately, yeasts are naturally metabolically unequipped to make use of a major component of plant matter, the cellulose polymers that make up plant cell...

  • Brain maturity scan

    Parents accustomed to plotting their baby's height and weight on a growth chart might one day find themselves also graphing their offspring's brain development too.
