An international team of scientists, including chemist Xiao Cheng Zeng of the University of Nebraska-Lincoln, has created what is in effect a nanoscale sieve that is very selective in what it will allow to pass through -- and performs in much the same way as the potassium ion channels that are vital components of virtually all living cells.

The sun breaks through the clouds - and surfaces start cleaning themselves! It may sound like magic, but in fact it's all thanks to the addition of titanium dioxide molecules. Activated by UV light, they trigger a reaction which destroys bacteria, algae and fungi, keeping items such as the armrests of garden chairs nice and clean.

A network of porous carbon tubes that is three-dimensionally interwoven at nano and micro level - this is the lightest material in the world. It weights only 0.2 milligrams per cubic centimetre, and is therefore 75 times lighter than Styrofoam, but it is very strong nevertheless.
