...Eventually, Fryer and his team got 143 schools to sign up. About half would be randomly selected as a control group, meaning the kids would not be paid. In the other half, students would earn money for their performance on 10 routine tests given throughout the year...
...classic experiment in support of this hypothesis took place at a nursery school at Stanford University in the early 1970s. There, researchers divided 51 toddlers into groups. All the kids were asked to draw a picture with markers. But one group was told in advance that they would get a special reward - a certificate with a gold star and a red ribbon - in exchange for their work. The kids did the drawings, and the ones in the treatment group got their certificates...
...early feedback was promising. Principals were lobbying to get their schools switched out of the control group and into the treatment group. Parents began using the paychecks as progress reports, contacting teachers to find out why their kids' checks had gone up or down. In Chicago, Duncan discovered that the program affected kids in ways he'd never expected. "I remember going to schools and seeing how excited the kids were when they got their checks. They were like pep rallies - but around academic success!" he says. Fryer appeared on The Colbert Report and CNN to talk about the experiment...

Around 40 lb. (18 kg) of highly enriched uranium (HEU) - with enough latent energy to destroy a portion of a city - had already been inventoried, secured and made ready for transport to a highly secure facility in the U.S. Running ahead of schedule, Bieniawski had taken...
