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.
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.
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
