Engineers Master Bicycle Aerodynamics With the Cervélo P5

At the Olympic level, where cyclists are in roughly the same physical condition, the difference between victory and defeat often boils down to a bike’s aerodynamics. The more smoothly air flows over a frame and rider, the less wind resistance he will feel and the faster he’ll go. Engineers at Cervélo used aerospace-grade computational fluid dynamics...

2012 Noctilucent Cloud Season Begins

Data from NASA's AIM spacecraft show that noctilucent clouds (NLCs) are like a great "geophysical light bulb". They turn on every year in late spring, reaching almost full intensity over a period of no more than 5 to 10 days--and the bulb is glowing. "They were visible to the north for about 3 hours as we flew between Ottawa and Newfoundland at 35,000...

Google experimenting with new search interface?

Google has put on its lab coat and turned on the Bunsen burner for an experiment in refined searches, according to a video captured by a Spanish tech site. The search giant is currently "testing new ways to refine searches," perhaps including a sidebar-free interface, going by the video that appears on the Spanish language Tecno-Net site (see...
