Imagine running a Google search for basketball videos, and having your computer sift through actual footage of online videos rather than just the text of the descriptions. A new type of software could enable computers to run searches inside videos, and pick out humans and objects alike.

Last year bicycle manufacturer Shimano debuted its years-in-the-making electronic gear shifting system, the Dura Ace 7970 Di2. Electronic shifting, which replaces traditional steel cables with a precise CPU-controlled system of sensors and motors, had long been a goal of bike makers. A workable solution, however, proved elusive. So when Shimano finally got it right with the Dura Ace system, it earned PopSci’s 2008 Best Of What’s New Grand Award in the Recreation category.

Soldiers may soon get greener rides on-base, after the U.S. Army announced the acquisition of 4,000 neighborhood electric vehicles.

The plug-and-chug vehicles come in both sedan and light truck models, and can charge their batteries at any three-pronged household outlet. Estimates put the savings over a six-year service lifetime at 11 million gallons of fuel, not to mention 115,000 tons of carbon dioxide emissions.

Adobe Flash has helped create many of the animations and games commonly found on websites. But Israeli director Ari Folman used the multimedia software to make Waltz With Bashir, an animated film which explores traumatic memories of his experience as a teenage soldier in the 1982 Lebanon War.

Buell did not break the mold when it made the 1125CR racing bike. Instead, it washed the mold away—to create a sturdier body.

As early as next year, if you are one of a lucky few, you may find yourself strapped in a six-passenger rocket some 50,000 feet above the Earth’s surface, bracing yourself as it disengages from the specially designed jet plane mothership, and shoots cannon-like 60 miles up into suborbital space at three times the speed of sound. If all goes well, you'll then get to unbuckle and float in zero gravity for a full fifteen minutes, spying on the earth’s curvature, all of North America and the Pacific Ocean.

This scenario is what Virgin Galactic is banking on. So much so that though the rocket is still unfinished they are already putting their first-picked passengers through flight training. And that is how Wilson da Silva, editor-in-chief and co-founder of Cosmos (the biggest-selling science magazine in Australia) found himself in Philly last month at the National Aerospace Training and Research (NASTAR) Center strapped into one of the most advanced centrifuge simulators on Earth shouting words that we cannot print here as 6 Gs of force pressed down upon him.

But first, some background.
