Engineers from Georgia Tech and Korea University have developed a new supercapacitor that’s designed to store more energy for longer – and it’s made out of ordinary paper, meaning it’s flexible enough to power wearable electronics.

Creating a material that can alter its optical properties in real time has proved challenging for scientists, but a team has finally achieved a major breakthrough by developing a material that can transition from clear to reflective and back again using an array of gold nanoparticles.

Researchers at Duke University have combined two techniques for fighting cancer. In one case, the mouse’s immune system not only destroyed the tumor, but stayed strong enough to ward off a later injection of cancer cells, raising hopes that the strategy could one day lead to a viable cancer vaccine.

Cancer treatments could benefit from being more like a sniper and less like a shotgun blast. A new technique is taking that approach, allowing doctors to attach drugs to white blood cells and sneak them past the tumor’s defenses for a targeted attack that doesn’t affect healthy tissue.

While removing the gold locked in electronics has heretofore been a toxic and inefficient proposition, researchers now think that a new process will make prospecting for the precious metals in electronics heaps more achievable than ever.

Scientists have found that by melting gold into the titanium mix they can produce a non-toxic metal that is four times harder than titanium itself, raising the prospect of more durable, longer lasting medical implants.

A nano-scale engine made from tiny charged particles of gold has just been declared the world's smallest by researchers at the University of Cambridge who created it.

A research team at the University of Saskatchewan has found what may be an inexpensive and environmentally friendly way of recycling gold from jewelry and electronics using a solution of reusable table vinegar.

Orbit1 is an electroplating solution aimed at small businesses and hobbyists, allowing them to coat any small object in a choice of metallic finishes. The device is relatively low cost, efficient to run, and pairs with a smartphone app to provide an accessible metal-coating experience.

Mining operations tend not be very good for the environment, nor does the disposal of treated solid waste that still contains potentially-toxic metals. Now, however, scientists are looking into taking that waste and harvesting its trace amounts of metals such as gold, silver and platinum.
