Imagine if your iPhone was the size of a small watch? It would be impossible to navigate without decent sized keys and icons. But what if you could project the screen onto your hand, and then type directly onto it? The size of our fingers is limiting how small devices can become. But with a new system called 'Skinput', a sensor around your arm teamed with a minute projector can literally turn your hand into a touch sensitive screen. At the moment the sensor is a bit bulky and unattractive but we are not far away from playing music and making phone calls on our hands. Watch this video and read accompanying article to see how it works.
Scientists working on the Organovo NovoGen printer recently created the first "printed" human vein. This technology could replace other toxic and carbon-heavy medicinal practices like using artificial body parts in the human body.
The printer is meant to be used in regenerative medicine. Instead of borrowing body parts from someone else - or yourself - the printer will just make a new part for you. The printer is loaded with cartridges of "bio-ink" a substance that acts as a kind of scaffolding for the cells to retain their shape. A sophisticated computer is linked to the printed that is pre-programmed with the 3D blueprint of whatever is being made. The computer instructs the printer to lay down two dimensional layers of bio ink and cells that eventually form into the 3D body part.article taken from www.inhabitat.com
