Self-healing bioplastic – just add water

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.

Smartphone microscope lens that costs just pennies to make

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.

Artificial muscle set for a stretch in space

When the Dragon spacecraft is propelled into space atop a Falcon 9 rocket this week on a resupply mission to the International Space Station (ISS), it will be carrying an artificial muscle material developed by Lenore Rasmussen and her company RasLabs. In addition to better prosthetic devices, it is hoped the material could find applications in robots on deep space missions. Read More

Shape-shifting nanoprobes report on internal body conditions using magnetic fields

Scientists have developed a new type of shape-shifting nanoprobe that can perform high-resolution remote biological sensing not possible with current technology. Around one-tenth the size of a single red blood cell, the nanoprobes are designed to provide accurate feedback on internal body conditions by altering their magnetic fields in response to their environment. The researchers predict wide-spread applications for the nanoprobes in the fields of chemistry, biology, engineering and, one day, to aid physicians in high-accuracy clinical diagnostics. Read More

Terminator-inspired tech could give traditional 3D printing a run for its money

A new approach to 3D printing promises to drastically speed up the 3D manufacturing process by "growing" objects out of a pool of resin rather than printing them layer by layer. Carbon3D announced its Continuous Liquid Interface Production technology (CLIP) on stage at the TED conference this week, claiming it can produce commercial-quality objects from a range of polymer-based material at speeds between 25 and 100 times faster than conventional 3D printing.

Tiny robotic hand-like grippers dissolve in the body after performing task

Creating swarms of soft, robotic hands that can safely dissolve within a living body once they've performed surgical procedures or delivered drugs just got a step closer thanks to work done by John Hopkins University scientists. They've created minute biodegradable microgrippers by adding stiff polymers containing magnetic nanoparticles to soft hydrogels, allowing them be magnetically guided to any location in the body.

More human-friendly antibacterial coating made from gold

We've been hearing a lot about the antibacterial qualities of silver, with silver nanoparticles finding use in everything from water filters to food packaging. Unfortunately, there are also concerns about the toxicity of those particles, particularly when they enter our bodies. Now, however, Polish scientists have developed what they claim is a safer alternative – an antibacterial coating that kills microbes using gold. Read More
