Burton rolls out True 3D laser plasma display article tells that Engineers from Burton Inc. in Japan have rolled out a “True 3D” display. This new system, which can function in air or under water, needs no screen of any sort, and the effect is quite impressive. This display is like Star Wars 3D holo display coming true. This system uses a laser to creates luminous points of light at desired locations in air or underwater. It works by focusing laser light, to produce plasma excitation from the oxygen and nitrogen in the air.
Mimicking the brain, in silicon article tells how new computer chip developed by MIT researchers models how neurons communicate with each other at synapses. The MIT researchers designed their analog computer chip so that the transistors could mimic the activity of different ion channels. With about 400 transistors, the silicon chip can simulate the activity of a single brain synapse. By the way there are about 100 billion neurons in the human brain, each of which forms synapses with many other neurons. The MIT boffins are planning to use their synaptic chip to model specific parts of the brain, such as the visual cortex. Compared to trying to simulate it in software on a supercomputer cluster, by using the analog synaptic chip, the simulation will run faster than your own brain does. (The brain has a 65Hz to 80Hz cycle time).
