Sunspots 368

Things I have recently spotted that may be of interest to someone else:

Science: National Public Radio reports that scientists at MIT have developed a computer algorithm that can tell when a smile is fake or genuine, and do so better than humans. Did you know that we smile when we are frustrated?

Wired reports on a chemical crime investigation -- in 1850.

Politics:  I was amazed to read (on PolitiFact, which is generally unbiased) that the rate of increase in US federal spending under President Obama was among the lowest of any president since Eisenhower. Some of the credit goes to Republicans in Congress.

Computing: Wired reports on efforts by orthodox Jews to keep the Internet morally safe. (There are allegations that the hierarchy may be unduly controlling access to information.)
