World's Fastest Computer Will Operate Like a Human Brain

AquaTop display is a projection system that uses white water as a screen surface. This system allows the user’s limbs to freely move through, under and over the projection surface. Using the unique characteristics of fluid, we propose new interactions methods specific to the projection medium, water. Our system uses a depth camera to detect input on and over the water surface to allow for interactions such as protruding fingers out from under the water surface and scooping up the water with both hands. This type of interaction is not capable with current impenetrable, rigid body, flat surfaces. For example, by floating one’s limbs on the water surface, it is also possible to fuse one’s body with the displayed objects for further augmented interaction by ‘becoming one’ with the screen.

Watch this video, it’s really cool.

Nanotools for Neuroscience and Brain Activity Mapping

Entirely new tools will ultimately be required both to study neurons and neural circuits with minimal perturbation and to study the human brain.

The Brain Activity Map (BAM) project has been proposed* to develop such tools. It has three goals:

  • Build neuroscience tools capable of:measuring the activity of large sets of neurons in complex brain circuits, with simultaneous measurement and manipulation of activity of thousands or even millions of neurons.
  • Computationally analyze and model these brain circuits.
  • Test these models by manipulating the activities of chosen sets of neurons in these brain circuits.”

Harvard Cracks DNA Storage, Crams 700 Terabytes of Data Into a Single Gram

The work, carried out by George Church and Sri Kosuri, basically treats DNA as just another digital storage device. Instead of binary data being encoded as magnetic regions on a hard drive platter, strands of DNA that store 96 bits are synthesized, with each of the bases (TGAC) representing a binary value (T and G = 1, A and C = 0).”
