High-speed

A new study has found a link between the rollout of high-speed internet services and a rise in obesity rates. The researchers who conducted the study attribute the increase to the effect of high-speed internet access on physical activity and eating habits.

We're starting off the week with a mechanical marvel: a homemade dragster with dual Rolls-Royce jet engines that's been 17 years in the making – and could potentially hit 400 mph.

Conventional helicopters have a built-in speed limit, imposed by the physical limitations of their top-rotor lift systems. This fascinating Airbus project has found a way to break through that speed limit, and it's already done it in flight testing.

Forget your friendly little electric air taxis. The USAF wants to take things up a notch with a new generation of high-speed vertical takeoff and landing aircraft. Thirty five designs have been presented, here's a peek at a few that caught our eye.

Man stands next to car and talks about it: it's a video format you've seen a thousand times. But this guy's name is on the back of the car, and the car is the extraordinary Koenigsegg Jesko. Join the man as he presents, then flogs, his latest beast.

Scientists and engineers often turn to high-speed cameras to better understand rocket launches, lightning and viper strikes, and now researchers in Switzerland are now proffering such folks a brand new tool they say will work with any kind of camera.

Central Japan Railway Company's high-speed maglev train has been busy setting records and then breaking them again in the past week. Most recently, the test train hit a top speed of 603 km/h (375 mph) on Tuesday, on the Yamanashi test track west of Tokyo.

The new Jet Capsule Reptile is equipped with a 570 hp Ilmor MV8 high performance marine engine, powering the compact vessel to maximum speeds of 50 knots – that's over 90 km/h (57.5 mph).
