Tackling Transport
|
|
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...

Scientists have developed a pain-free injection system to immunise people against influenza. Writing in the current edition of PNAS, Emory University researcher Richard Compans and his colleagues describe how a system of microneedles, each measuring less than a tenth of the diameter of a traditional...
Scientists in Japan have found a strong link between higher levels of the metal lithium in tap water and a reduced incidence of suicide.
Hirochika Ohgami and Takeshi Terao from Oita University led a team who measured the levels of lithium in the tap water of 18 municipalities of a region of Japan c...
US scientists have developed a method to selectively shut off genes linked to inflammation all around the body. Writing in this week's Nature, University of Massachusetts researcher Michael Czech and his colleagues describe how they have produced gene-silencing particles which are orally active and ...
News came out this week that it isn’t just people who enjoy a moving and dancing to favourite but birds, it turns out, also like to boogie.
Aniruddh Patel from the Neurosciences Institute in San Diego, first saw Snowball the sulphur crested cockatoo on a video clip on the website youtube bobbing hi...

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

Interviews
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...
Stephan Zielinski has made his own viral music from swine flu using a simple sequence of amino acids found in swine flu proteins...
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...
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 actually spilling out in...
How can we solve the problem of steering articulated trailers independently? Andrew Odhams believes he has the answer.

We're constantly pulled this way and that by the gravitation of the Earth, the Moon and the Sun - but do we weigh more or less at night?
