Tackling controversial technology face by face
Serious questions abound about how and when facial recognition technology should be used, and whether the positives—identifying a suspect or preventing a terrorist attack—outweigh the negatives—infringement on privacy rights.
Rebuilding spinal cords with an engineer's toolkit
Like an earthquake that ruptures a road, traumatic spinal cord injuries render the body's neural highway impassable. To date, there are neither workable repairs nor detours that will restore signal flow between the brain and limbs, reversing paralysis.
University of Florida performs its first retinal implant
The University of Florida performs its first retinal implant with the Argus II by Second Sight. The Argus II is an epiretinal implant consisting of an inner electrode array placed in the eye where it can stimulate the remaining cells in the retina, effectively taking the place of the rod and cone cells that have died off due to degenerative retinal diseases like retinitis pigmetosa.
Next gen batteries could provide power to microsatellites, cubesats
The size of the battery is so thin (2-3 millimeters) that it is a prime candidate for use in microsatellites, including CubeSats.
Flashcharge Batteries is a company based in Florida developing fast-charging energy storage devices based on redox polymers. They claim 60x faster charging rates, 20x more power and 50x longer cycle life than conventional Li-ion batteries.
Wearable allows people with vision loss to actually see
eSight's wearable, hands-free headset houses a small, high-speed camera that captures everything the eSight user is looking at.
7th Annual CAFE Electric Aircraft Symposium: First day
This excellent event "7th Electric Aircraft Symposium" in Santa Rosa, USA was acclaimed as the best ever in the series. Over 150 people attended, an eclectic mix from NASA and Siemens to hobbyists, universities and technology startups were there.
City Labs makes first commercial tritium battery
The NanoTritium can travel into enemy territory, plunge to the bottom of the ocean and even settle into the human heart. And it keeps going, even through extreme temperatures and vibration, for 20 years or more.
Spin battery uses new source of energy
Researchers have been able to prove the existence of a "spin battery," a battery that is "charged" by applying a large magnetic field to nano-magnets in a device called a magnetic tunnel junction.
