Cast your mind back to high school chemistry and you might remember the van der Waals force: The weak bond between molecules, caused by the way their electrons shift at the atomic level. Now, for the first time, those tiny forces have been measured between two atoms.
Geckos, being master of the van der Waals force, climb up glass walls like it's no big thing. But can they do it when they're dead? Scientists have found out that they can, and that has important implications for technology.
Humans have many scientific achievements, but when it comes to the van der Waals force, we have been bested by geckos.
