Science has turned its torch to many corners of the animal kingdom in the pursuit of advanced adhesives. Immoveable mussels, grippy geckos and stubborn shellfish have helped nudged these efforts along in the past, and now another critter has emerged with a few sticky secrets of its own. Researchers have replicated the adhesive secreted by sandcastle worms to form a new kind of underwater glue, a substance they say could find use in a number of applications including tissue repair and dentistry.
Having faced off the Green Goblin and Mysterio, Spider-Man has been defeated by his greatest enemy; maths. According to a team of scientists from Cambridge University, for the webslinger to stick to a wall, he'd need hands and feet equal to 40 percent of his entire body surface area. Though this may dismay web head's fans, it may shed insights into how to improve gecko-like adhesives.
The natural stickiness of gecko's feet has inspired decades-long research efforts to develop advanced adhesives. Now a company spun out of a university research group called nanoGriptech has taken the science out of the lab and into the market, through a number of newly available products promised to deliver enhanced grip and reusability.
A glue that performs at a high-level in wet environments could bring about all sorts of possibilities in areas like surgical care and ship maintenance. A somewhat common approach to this problem has been trying to replicate the freakish ability of mussels to bind themselves to boats and jetties, but a team from Singapore's Nanyang Technological University is coming at it from a slightly different angle by developing a glue that hardens when an electrical charge is applied.
Nowadays, you can track the location of belongings such as wallets, bikes and bags with small GPS trackers – and the coin-sized, wirelessly-rechargeable TrackerPad is perhaps the smallest of the lot.
The ability of mussels to stubbornly bind themselves to underwater surfaces has intrigued scientists for years. If this ability could be recreated in the lab, it could lead to new adhesives for all kinds of applications. A team of Korean scientists has now developed a surgical glue inspired by these natural wonders that's claimed to be cheaper, more reliable and incur less scarring than existing solutions.
Ants have a reputation as the hard workers of the animal kingdom, in part because they can lug around impressively heavy loads with respect to their size. But tiny new robots being developed at Stanford University are giving them a run for their money with the ability to pull up to 1,800 times their own weight.
Mussels have an incredible ability to cling to wet surfaces. It's an ability that scientists are trying to replicate
for use in man-made adhesives. That adhesion can't be turned on and off
as needed, however, limiting its potential applications. That's where
the Northern clingfish comes in. It can suck onto rough, slimy surfaces,
supporting up to 150 times its own body weight when lifted. That said,
it can also just let go and swim away whenever it wants. Scientists from
the University of Washington now understand how it's able to do so, and
are looking at applying the principle to fields such as surgery and
