The oldest use of glue can
be traced back to 80.000 years ago. At that time Neanderthals melted birch wood on stoves using with a
special technique, which obtained a sticky substance similar to
tar they used to build hunting tools.The most powerful glue in nature is produced by a bacterium, the Caulobacter crescentus, which produces it to attach to rocks and walls.
The most powerful glue produced in the laboratory has been synthesized by researchers at MIT in Boston who were inspired to a protein secreted by mussels.
In medicine a material has been developed similar to the gels, inspired by the sticky secretions of snails and insects, that may function as a surgical glue stable, elastic and insoluble in water. This compound would allow applications which were impossible until now such as applying patches directly on to a patient's heart. Further trials are currently under way (source: Science Translational Medicine)
The
Guinness Book of World Records has awarded the prize for the
"heaviest vehicle lifted with glue" to Loctite. It
took 9 drops of common Super Glue Universal 3G to
paste the ceiling of a pick-up truck to a city car to give a
total weight of 5.02 tons.
