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.
Inspired by the way plants grow, MIT researchers designed a flexible robot appendage that can work in tight spaces but is rigid enough to support heavy parts or twist tight screws. From MIT News: The appendage design is inspired by the way plants grow, which involves the transport of nutrients, in a fluidized form, up […]
Penn State engineers have devised a circuit inspired by the way barn owls can so precisely determine where a sound is coming from and track their prey in the dark. Eventually, this fine example of biomimicry could lead to more accurate electronic navigation devices. Essentially, the owl’s brain calculates the difference between when a sound […]
The more you use your computer, the more it becomes possible for others to use it too. Where there are anti-virus systems, there are hackers looking for a way to get around them. That’s why it’s important to get software that doesn’t just passively scout for viruses in the background. The folks behind GlassWire have […]
Knowledge is power. It’s a cliché, but sometimes things turn into a cliché because they’re true. If you’re making your way through the world of business and entrepreneurship, it only makes sense to read about the insights of people who have climbed that ladder before you. Trouble is, the modern workday doesn’t leave a lot […]
As much as some of us fear the loss of our jobs to robots, there’s one job we’re pretty sure they are welcome to: vacuuming. There’s nothing quite like kicking back and watching a robot vacuum do one of the most time-consuming tasks on the household chore list. And there are few ‘bots that do […]
