Tectoy has opened preorders for a new production run of the Sega Mega Drive (known as Sega Genesis in the US), which is modeled on the original, plays existing cartridges and uses wired controllers, but also features a couple of modern conveniences like an SD card slot and 22 pre-installed games.

Researchers have developed a system that bypasses spinal injury by allowing the motor cortex to communicate wirelessly with the lower spine, and demonstrated that it can restore almost normal walking patterns in partially paralyzed macaques.

A new study suggests that the Earth’s vegetation has upped its game to help offset carbon emission growth. After a 40-year upward trend, the rate at which atmospheric CO2 levels increased plateaued between 2002 and 2014, thanks to plants plucking more CO2 out of the air than they have previously.

The firm behind the sensor of the Leica M has developed a 48-megapixel CMOS offering with a global shutter. In addition to being suited to shooting fast-moving objects without distortion, the CMV50000 from CMOSIS, can also support 8K video resolutions at 30 fps.

Leica has launched the latest version of its mirrorless APS-C camera, the Leica TL. The new model offers a bigger internal memory and improved autofocus over the 2014 original, but retains those good looks and machined aluminum body.

The Piaggio Group has announced that possibly the most iconic scooter of them all is about to go electric. The Vespa Elettrica concept has been revealed at EICMA in Milan, Italy, this week.

Even though it was built at the height of the Cold War and hasn't flown in over 17 years, the SR-71 Blackbird still looks like it fell out of the future. So how was it built, and what was it like to fly this supersonic denizen of the edge of space?

A transportable chemical reactor​ developed at Germany's Karlsruhe Institute of Technology (KIT) and spinoff company Ineratec that uses solar power to convert CO2 from the air and regenerative hydrogen from electrolysis into liquid fuels will be tested in a pilot plant.

After being diagnosed with leukaemia, a 10-year-old girl from Australia was inspired to invent a better Band-Aid dispenser. The Faster-Aid works like a roll of tape that's resealable to keep the bandages sterile, and it won Origin’s littleBIGidea, an Australia-wide competition for young inventors.
