A study of skin wound healing in 40 (human) volunteers has found that electrical stimulation significantly speeds up the healing process. The researchers hope to now develop and test dressings and devices that could be used in treatment of human or veterinary surgical wounds, sports injuries, and other serious skin trauma.

It's one thing to 3D-print something as advanced as a jet engine, but it's another to fuel it up and push the start button. That's the step that GE Aviation took when it recently fired up a simple jet engine made entirely of 3D-printed parts in a test stand normally reserved for commercial jet power plants.

Using a matrix of nano-sized memristors, researchers working at the Royal Melbourne Institute of Technology (RMIT) and the University of California, Santa Barbara claim to have constructed the world’s first electronic memory cell that effectively mimics the analog process of the human brain. By storing memories as multiple threads of varying information, rather than a collection of ones and zeroes, scientists believe that this device may prove to be the first step towards creating a completely artificial, bionic brain.

One thing that space definitely lacks is "down." Zero gravity isn't just disorienting, it also affects astronauts' health. Massachusetts-based Draper Laboratory's NASA-funded Variable Vector Countermeasure Suit (V2Suit) uses a new spacesuit technology to create a sort of artificial gravity that provides astronauts with a sense of up and down while helping relieve some of the detrimental effects of weightlessness.

Artificial muscles could one day revolutionize fields such as robotics, prosthetics and nanotechnology. So far, we've seen examples made from materials like electroactive elastomers, crumpled graphene, and vanadium dioxide. The problem is, most artificial muscles can only expand in one direction, or contract in the other. Now, however, scientists from National Taiwan University have gotten around that limitation using gold-plated onion cells.

In order to confirm that a patient presenting with a heart attack has in fact had one, doctors typically use bulky, expensive lab equipment ... which isn't always available to clinicians in developing nations or rural locations. That's why scientists from Korea's Pohang University of Science and Technology have created a simple thermometer-like device that reportedly does the job.

When it comes to donated blood, type O is special. It can be given to anyone, regardless of their blood type. By contrast, type A can only go to A or AB patients, and B can only go to B or AB patients. Additionally, type O patients can only receive O. Thanks to new research, however, it may soon be possible to give anyone whatever type of blood happens to be available, with no ill effects.

In seeking a compromise between helicopters and fixed-wing aircraft, engineers in recent years have opted for tilt rotors, but NASA has dusted off and improved on a tilt wing aircraft design that takes off and lands like a helicopter and flies like an airplane. Called the Greased Lightning, or GL-10, the unmanned prototype made a successful vertical takeoff and transition to horizontal flight at Fort A.P. Hill, not far from NASA's Langley Research Center in Hampton, Virginia.

Billionaires who made their cash in dot-coms from the 1990s successfully launching commercial rockets is officially a trend, now that Jeff Bezos has followed in the footsteps of Elon Musk with Wednesday's successful test flight of Blue Origin's New Shepard space vehicle.

A new nanoscale plasmon laser developed at Northwestern University changes color in real time through a process as simple as swapping one liquid dye for another. The scientists responsible for the technology claim this is the world's first liquid nanoscale laser, and it could find uses in medical diagnostics as well as military or security applications.

Until the 1960s, Japan's three I-400-class subs were the largest submarines ever built. They were so large, in fact, that they could each carry and launch three Aichi M6A Seiran amphibious aircraft. The idea was that the submarines could stealthily bring the planes to within striking distance of US coastal cities, where they could then take off and conduct bombing runs. Now, for the first time since it was scuttled at the end of World War II, one of the sunken subs' aircraft hangars has been photographed.

Small airports are often in a no-win situation. They don't have much traffic because they don't have an adequate tower system, and they don't have an adequate tower system because they don't have much traffic. That could be about to change, with the opening of the world's first remotely operated air-traffic control system in Sweden. Thanks to the Remote Tower Services (RTS) system, the first plane landed last week at Örnsköldsvik Airport, but it was controlled from the LFV Remote Tower Centre 123 km (76 mi) away in Sundsvall.

We've been teased with the prospect of a flying car for years now, with many designs, like the Terrafugia Transition, having been under development for some time but yet to arrive in garages or hangars. The Braunschweig-based company, Carplane hopes to square the circle with a twin-fuselage roadable monoplane that made its first public appearance in prototype form at the recent AERO show in Friedrichshafen, Germany.

Audi is making a new fuel for internal combustion engines that has the potential to make a big dent when it comes to climate change – that's because the synthetic diesel is made from just water and carbon dioxide.

Researchers from the Karlsruhe Institute of Technology (KIT) in Germany have studied the wings of glasswing butterflies in an effort to determine what causes their low-reflective nature. It's believed that the findings of the study could lead to less reflective screens on mobile phones, tablets and other devices.
