Slug mucus sticks well to wet tissues, which appeals to surgeons. David J. Mooney of Harvard University made a glue similar to slug snot, and "tested the adhesive on pig skin, liver, heart, and cartilage and found that it was stronger than both cyanoacrylate (superglue) and a surgical sealant called CoSeal," reports Chemical and Engineering News.
Mooney and his colleagues came across a paper analyzing the material properties of mucus from a type of slug (Arion subfuscus). The sticky mucus has two components: polycations that help the mucus adhere to surfaces through electrostatic interactions and covalent bonding, and a tough matrix that absorbs and dissipates stress. This combination allows the slug to stick strongly to a surface by resisting forces—such as those from wind, rain, or the beak of a hungry bird—that could dislodge it.
Most aquatic animals propel themselves with a tail or fluke, so roboticists have long been interested in the remarkable speeds possible by mimicking sea lion propulsion with front flippers.
When fire ants dig out a new nest underground, a small number are actually doing most of the work while the rest dilly-dally. Apparently this is actually an effective division of labor because it prevents the insects from getting in each other’s way. Now, Georgia Tech researchers suggest this approach could be help future robot […]
Earwigs can fly but they mostly live underground, intricately folding their wings into a surface area that’s 10 times smaller than when they’re opened up. According to new research, the folds “cannot be sufficiently described by current origami models.” The earwigs manage the marvelous by incorporating a bit of stretch into the joints where the […]
