Polite Robots Show Glimmer Of Self-Awareness

Popular Science: 

The robots were programed to think that two of them had been given a “dumbing pill” that would make them unable to speak (actually just a button that silenced them). However, they didn't know exactly which two of them had been silenced. When the robots were asked to answer which two had been given the pill, all of them tried to respond: “I don’t know.” Since only one was actually able to utter the words, it heard its own voice and recognized it wasn't among the two who had been silenced. That robot then responded: “Sorry, I know now. I was able to prove that I was not given a dumbing pill.”

Face It, Your Brain Is a Computer

Gary Marcus in The New York Times: 

There is much that we don’t know about brains. But we do know that they aren’t magical. They are just exceptionally complex arrangements of matter. Airplanes may not fly like birds, but they are subject to the same forces of lift and drag. Likewise, there is no reason to think that brains are exempt from the laws of computation. If the heart is a biological pump, and the nose is a biological filter, the brain is a biological computer, a machine for processing information in lawful, systematic ways.

The sooner we can figure out what kind of computer the brain is, the better.

Big Bird, big brain

The Economist on Sesame Street: 

Since 1969, “Sesame Street” has been introducing small children to letters and numbers by using clever skits and songs performed by Muppets and celebrities. Patrick Stewart, for instance, reworked Hamlet’s soliloquy as an ode to the letter B (“B or not a B, that is the question”). Now a report by two economists, Melissa Kearney of the University of Maryland and Phillip Levine of Wellesley College, has tracked the first generation of watchers (who were under six in 1969). It reveals that children who had access to “Sesame Street” ended up better prepared for school and were 14% less likely to fall behind in class. 
...
The show’s effects are not unlike those of Head Start, a federal scheme that provides poor families with services that include school-based early education. But it costs a fraction as much, says Ms Kearney. “Sesame Street” is not a replacement for early education, which most studies agree is vital; but it is certainly a very affordable supplement. “In essence,” she says, thinking of massive open online courses, “Sesame Street was the first MOOC.”
