Scientists connect a human brain and 'rat cyborg' brain together (2 minute read)
A Chinese research team has developed a wireless brain-to-brain system that allowed a human to control and move a ‘rat cyborg’ through a maze. Researchers were able to translate signals from an electroencephalogram attached to humans into instructions that stimulated a rat’s brain to move in a certain direction. While scientists have previously been successful in creating other brain-to-brain control systems, this is the first time it has been used to solve a complex navigation task.
Playing Pictionary against computers could help AI learn common sense (2 minute read)
The Allen Institute of Artificial Intelligence (AI2) today released an online Pictionary-style game called Iconary.

Users will draw scenes based on a text description, and the algorithm will have to identify what objects are in the picture, figure out how these objects relate to each other, and translate the image into text that humans can understand.
