Van der Waals forces act like a sort of quantum glue on all types of matter. Using a new measuring technique, scientists from Forschungszentrum Jülich experimentally determined for the first time all of the key details of how strongly the single molecules bind to a surface.

The uncanny ability of geckos to adhere to nearly any surface and even walk on ceilings is the result of a biological mechanism in their toes that the lizards can instantly turn on or off, according to new research appearing in the latest edition of the Journal of Applied Physics.

Human adhesives are famed for their fallibility. Gooey glues soon lose their grip, are easily contaminated and leave residues behind. But not gecko feet. Geckos can cling on repeatedly to the smoothest surfaces thanks to the self-cleaning microscopic spatula-shaped hairs (setae) that coat the soles of their feet.


Word of the Day
alicorn
  • The horn of a unicorn considered as a medical or pharmacological ingredient.
  • A winged horse with a single horn on its head; a winged unicorn.
The word 'alicorn' comes from Italian alicorno, already associated with unicorns and reinterpreted, popularized by Bearing an Hourglass (1984) and other fantasy novels by Piers Anthony.
