Imagine if things like undersea cables or medical implants could simply
heal themselves back together if severed – it would certainly be easier
than having to go in and fix them. Well, scientists at Pennsylvania
State University are bringing such a possibility closer to reality.
They've created a moldable polymer that heals itself when exposed to
water – and it's based on squid sucker ring teeth.
Researchers at MIT have developed a new material that shows promise for use in ultra-long drug delivery systems, as well as electronic monitoring of the stomach and weight-loss intervention. A type of polymer gel, the material is flexible and pH-responsive, allowing it to reside in the stomach for long periods of time before safety dissolving in the small intestine.
Microscopes can be expensive pieces of gear, making access difficult – or non-existent – for students and medical staff in isolated and poorer locales. To help address this, researchers at the University of Houston (UH) have fashioned a lens designed to fit on almost any smartphone. It has the ability to magnify images up to 120 times their original size, and at an estimated production cost of just three cents per lens.
