Duct tape that never loses its stick. Bandages that come off without sticky residue or an "ouch."
Gecko feet may hold the key to the development of synthetic self-cleaning adhesives, according to a biologist from Lewis & Clark College. The research is published in the online early edition of the Proceedings from the National Academy of Sciences of the United States, or PNAS (http://www.pnas.org) during the week of Jan. 3, 2005 (Article #08304: "Evidence for self-cleaning in gecko setae").
"How geckos manage to keep their feet clean while walking about with sticky feet has remained a puzzle until now," said Kellar Autumn, associate professor of biology at Lewis & Clark College. "Geckos dont groom their feet, and the adhesive on their toes is much too sticky for dirt to be shaken off. Conventional adhesives like tape just get dirtier and dirtier, but we discovered that gecko feet actually become cleaner with repeated use."

A study carried out by an international team of researchers and published in the journal Physical Review X shows that ion-trap technologies available today are suitable for building large-scale quantum computers. The scientists introduce trapped-ion quantum error correction protocols that detect and correct processing errors.
In order to reach their full potential, today’s quantum computer prototypes have to meet specific criteria: First, they have to be made bigger, which means...
