Tackling Transport

Boeing 737 passenger jet (c) Barcex

On this week's Naked Scientists, we explore the engineering and materials science that will give rise to the future of transport!  We find out how jet engine parts grown as a single crystal of superalloy will make flights more efficient, and how clever computer control make it easier for trucks to turn.  Plus, pain-free injections for the needle-phobic, Boogie with birds and the synthesised sound of Swine Flu proteins.  In Kitchen Science, Ben and Dave look back over 7000 years to seek the science of the wheel...

  • 12:18 - The Genetics of Swine Flu

    People are concerned about swine influenza from Mexico but surely more answers than any can be obtained by sequencing the virus and understanding what its genetic story is...

  • 17:59 - Musical Viruses

    Stephan Zielinski has made his own viral music from swine flu using a simple sequence of amino acids found in swine flu proteins...

  • 21:56 - Why do wheels work?

    The wheel is something we have been taking for granted for the last 7000 years, but why is it so effective?

  • 26:18 - Making Superalloy Jet Blades

    Dr. Howard Stone is looking for ways to get the most out of metals as we use them to make jet engine blades. Advances in technology can make them longer lasting, safer and more efficient...

  • 32:38 - F1 Inspired Wheelchairs

    Formula 1's a fast paced world where cars can race at up to 220 mph in certain conditions but for these cars to reach these speeds and drive smoothly and safely they need to be at the forefront of science and technology. But did you know that the science behind Formula-1 is act...

  • 40:27 - The Science of Driving a Heavy Goods Vehicle

    How can we solve the problem of steering articulated trailers independently? Andrew Odhams believes he has the answer.

  • 47:13 - Do we weigh less at night?

    My question is do we and objects weigh less at night time? I could imagine that an additional gravitational upward pull of the sun during day time will work to a certain degree against the downward pull of the earth.
