A soybean-shaped bacterium called Caulobacter crescentus, found in freshwater and seawater, makes one of the strongest adhesives in the world. Now high-resolution video microscopy is shedding light on how it can carefully use this adhesive, like a super-precise application of superglue, to stick on surfaces in wet environments.
De-bearded mussels are not only delicious — soon, they might improve medical implants. Scientists can now reproduce the sticky gloop that mussels use to anchor themselves to rocks, leading to a new breed of self-healing, waterproof elastic adhesives that can be used for underwater materials or even for biomedical applications.
Scientists come a step closer to creating the perfect adhesive

Spiderman, meet Gecko Guy. Ronald Fearing and his group at the University of California, Berkeley have engineered an adhesive material so sticky that a person clothed in a suit made of the stuff might actually be able to climb walls like the web-slinging comic book hero. The work was inspired by the gecko, which takes advantage of van der Waals forces—the cumulation of millions of molecular-level attractions—to keep its hair-covered feet stuck to sheer surfaces.
Weve reported on gecko-inspired work before, but Fearings latest achievement is a big step towards getting more of these gecko-gadgets out of the lab and into the world.
