What happened to lunch? New study shows skipping lunch common in children

According to new analysis of data from the 2009-2012 National Health and Nutrition Examination Survey that evaluated eating patterns of 3,647 children ages 4-13 years, skipping lunch is a common practice among children and adolescents, with 13 percent of younger children and 17 percent of 9-13 year olds skipping lunch on a given day. The study found that the behavior persisted throughout the week with nearly a quarter of 9-13 year olds skipping lunch on the weekends. —> Read More

‘Smart’ Headlights Use Eye-Tracking To Beam Light Where Drivers Look

From self-driving cars to drunk driver-detecting lasers, researchers are using technology to help make the road much safer.

And now, engineers at General Motors (GM) are developing “smart” headlights that beam light precisely where a driver is looking — an invention that could improve visibility for drivers at night.

“We want to actually implement the idea that the human eye is capable of guiding and regulating light,” Ingolf Schneider, director of lighting technology at GM’s subsidiary Opel manufacturer headquartered in Rüsselsheim, Germany, told Opel Post. “The eye tracking principle relies on tracking via camera and intelligent analysis of eye movements using a special algorithm.”

How it works. The eye-tracking system is made up of a single dashboard camera equipped with infrared sensors. The camera scans the driver’s eyes and other points on the face more than 50 times per second. Based on the scanned data, electronic motors then change the direction of the headlights.

An algorithm built into the eye-tracker adjusts for quick glances, so that the light doesn’t dart around with every movement of the eye, Discovery News reported. And, no matter where a driver looks, the headlights always illuminate the road in front of the car.

“Another major benefit is that the eye-tracker doesn’t have to be individually calibrated for a particular driver,” Schneider said in a written statement. “The system works perfectly with anyone behind the wheel, no matter what their size.”

As the eye-tracking headlights are still in the early stages of development, the concept will likely take several years to be implemented. —> Read More

Here’s What Happens When A CD Shatters Into Smithereens In Slow-Motion

With streaming music and digital downloads taking over, what to do with old CDs? Use them in a science experiment, of course!

Gavin Free and Dan Gruchy, also known as “The Slow-Mo Guys,” have done just that — spinning CDs at high speeds and capturing in slow-mo the incredible moment when they shattered. Just check out the video above.

(Story continues below GIF).

The duo used a vacuum motor to get one of the discs spinning at a speed of 23,000 RPM — and then used an ultra-high-speed camera to film the CD explosion at a rate of 170,000 frames-per-second.

“That’s the fastest thing we’ve ever filmed,” Gruchy says in the video, “and the fastest frame rate as well.”

See ya, CDs!
