In the age of Blu-Ray and Hulu, maybe DVDs are becoming less relevant. But researchers have just made a crazy invention with one: a device that simply and quickly detects HIV.
A team from the KTH Royal Institute of Technology in Stockholm turned a DVD drive into a laser scanning microscope that can accurately analyze blood and perform cellular imaging. That means it can test for HIV--and spit back results in minutes.
Construct a high-def front projector for hundreds less than store-bought models

Want some real home theater bragging rights? Instead of buying a projector capable of casting a 14-foot image at 1080p (progressive) resolution-the highest high-definition there is-build one yourself. After all, the front projector´s innards are simple: an LCD lit by a superbright lamp, and a few lenses to magnify and sharpen the image. Retail models start at around $800 and use proprietary $400 lamps that burn out every few years. But cheaper lamps work equally well, and none of the other parts are very expensive. Why not put one together yourself?

HDTV sets are stunning—until you pop in a movie and are reminded that DVDs are not recorded in high definition. At 480 lines of resolution, they don’t even begin to take advantage of a 720- or 1,080-line display. That will change later this year when Toshiba introduces the first high-def disc player for the U.S. market. Toshiba’s breakthrough box, an HD DVD player that at press time was still unnamed, will cost about $1,000 (toshiba.com).
Five amazing, clean technologies that will set us free, in this month's energy-focused issue. Also: how to build a better bomb detector, the robotic toys that are raising your children, a human catapult, the world's smallest arcade, and much more.
