The hummingbird’s super-fast wing beats are among the most energy-intensive movements in the animal kingdom. Still, the birds can fly 4,000 metres above sea level, where there is very little oxygen. Scientists have now figured out how this is possible.
A new, superconducting oxide system multiplies the electron mobility in electronic oxide transistors. Benefits include superconducting nanotransistors, self-charging electronic devices and a new type of RAM.
Finnish researchers have discovered that wolves were domesticated by European hunter-gatherers between 19,000 and 32,000 years ago. The analysis cannot, however, be used to determine the origin of the dog, argues Danish DNA scientist.
CERN’s Large Hadron Collider particle accelerator smashes protons together with such great force that it can give birth to hitherto unknown particles. A new method makes it easier to recognise the new particles.
