Fitness Trackers Dinged Many buy, and use fitness trackers in hopes that the devices will encourage them to work out more — and lose weight. Except they don't. So says a new study from JAMA, The Journal of the American Medical Association, which found those who used trackers lost less weight than those who didn't. After two years, people who used fitness trackers lost just 7.7 pounds but those who did not lost almost 13 pounds. Researchers who tracked the nearly 500 participants now believe that wearables which "monitor and provide feedback on physical activity may not offer an advantage over standard behavioral weight loss approaches."

The three researchers, who work with Keen Security Lab, were able to control the Tesla Model S in both parking and driving mode, they reported. The video shows the team hacking into the software to open the car's sunroof, turning on exterior lights and also move the car's seat—and say they could also hack into other Tesla models as well.
