An apple a day might keep away more than the doctor. HortResearch, a New Zealand company with 400 scientists studying all things fruit, has early data that suggests a specific (mystery) fruit can delay fatigue by 20 percent and increase muscle power by 70 percent. But don't raid the produce aisle quite yet. Hort won't say which fruit has shown the benefits and also notes their version is a variety bred internally for the right compound interactions. In other words, for those of use not lucky enough to be Hort test subjects, it doesn't exist.

Nike is to Apple, as Adidas is to . . . Samsung? In the race to make people run, Adidas is gaining steam with this week's European release of miCoach. Like the iPod-based Nike + system, at the heart of miCoach lies a Samsung phone that similarly follows your progress and motivates your workout.

The phone wirelessly tracks data from a chest strap heart rate monitor and a stride sensor that hooks onto your laces (an advantage over Apple's system since it lets you keep your sneakers). Workouts are built and analyzed on a full-service website complete with graphic data and recommendations for your fitness objectives.

This is probably the first and last reporting on rugby you’ll see from Popular Science, but when you broadcast a sport live in 3-D (while serving alcohol) some coverage is deserved. On Saturday, a select group of executives got to watch the battle between England and Scotland in three dimensions on a movie screen in West London. For the English in attendance, the extra-vivid depiction of a 15–9 loss to the Scots likely required additional pints, but more importantly spoke to a larger trend in making live 3-D broadcasts a reality. The 2007 NBA All-Star game was similarly telecast in an extra dimension for a few privileged viewers last year while U2 even offers their first 3-D concert to cost-conscious fans via video.

In an unexpected move, the International Federation of Association Football, soccer’s governing body, this week pulled the plug on plans to implement a state-of-the-art scoring system. Instead of introducing the dual technologies—a sidelines camera and in-ball chip—officials have opted for a decidedly low-tech solution for better determining whether a goal was scored: two additional linesmen.
