As much as I’m not looking forward to the emergence of the cicadas, I’ve got to say I’m incredibly impressed by the biology behind their arrival. This amazing video chronicles the short, above-ground life of the cicadas. Watch them in all their HD glory.

Regal Cinemas plans to distribute new closed-captioning glasses from Sony to more than 6,000 screens across the country by the beginning of summer and hopes to have them in all their theaters by the end of the year. As you can see from the picture (right), the glasses look kind of like bulky 3-D glasses except these are used for captioning, not 3D. The captions are projected onto the glasses and appear to float about 10 feet in front of the user at the bottom of their field of vision. In ddition, the glasses also provide "descriptive narration" which describes the action on the screen for the visually impared and they can also boost the audio levels of the movie for those who are hard of hearing.
Watch this video and decide for yourself if the current reality of wealth (not income) distribution in the U.S. is healthy and/or fair.
When kids first enter primary school, they spend their time doing creative things like drawing, painting, building, and experimenting. But after those first years, the creativity stops. Dr. Resnick is working to change that. He and his team have developed new ways to help older students engage with technology in order to encourage them to create and experiment the way they did in kindergarten.
When I commuted to Tysons from DC, I would have lots of time stuck in stop-and-go traffic to consider the reasons and causes for traffic slowdowns. It seemed that often, we’d all be slowing down and then speeding up again for no reason. I always speculated that sudden braking could cause a wave of slowdowns that would propagate backwards for hours/miles, leading to the annoying slow-down-speed-up cycle.
A team of Japanese researchers recently created an experiment to show that the effect of breaking can easily create traffic jams. It’s all just physics. Their experiment shows that when the density of cars on the road passes a certain threshold, traffic jams will be caused simply by the multi-particle interactions of the system. In layman’s terms, drivers inconsistently hitting their breaks will cause a wave of stop-and-go backups behind them.
