The aftermath of violent crimes is nothing like what we see on TV, says Stephen Morgan, a forensic analytic chemist. "Crime scenes are messy, chaotic. There's a lot to look at." Too much, in fact. What's needed are methods to simplify the forensic process without damaging evidence at the scene. These three breakthroughs will do just that.

NASA’s high-resolution 3-D maps of the moon’s pockmarked terrain the most precise topographic measurements to date—bring us one giant leap closer to a return mission. To create the map, the laser altimeter LOLA on the Lunar Reconnaissance Orbiter bounced five laser beams off the surface of the moon 28 times per second and measured the duration of their return flight to gauge elevation. NASA operators calculated the distortion, or spread, of the beam to find what scientists call roughness; the more distortion there was in the beam, the bumpier the landscape.
Possibly, but only with a lot of luck and some autopilot assistance. Amateurs have landed smaller private planes after the pilot became incapacitated, but outside of 1970s disaster movies, it has never happened with a commercial passenger aircraft.

Consider this the end of fussing with new remotes. Philips’s uWand drops complicated menu buttons for a language that’s already universal: gestures. Similar to a Boxee Box remote in looks and a Wii controller in functionality, this remote uses an infrared beam to send its location to a receiver connected to a TV.
Nearly a decade ago, NASA built an Earth-monitoring satellite that could have observed global warming in action. Then the agency stashed it in a warehouse in Maryland, where it remains to this day By Bill Donahue

Microchips restore sight in patients with degenerative vision loss

More than 100,000 Americans have suffered significant vision loss from retinitis pigmentosa, a genetic disorder that is the most common cause of childhood blindness. Now a team of German researchers, led by neuroophthalmologist Eberhart Zrenner of the University of Tubingen, has developed a microchip that can restore their sight. Within days of receiving the implant, patients can see geometric patterns and letters. Over time, some have developed the ability to tell a fork from a spoon, identify shades of gray, read words, and even detect emotion on people's faces.
Follow these step-by-step instructions to light up your Easter eggs:
1. Cut a half-inch diameter hole in one end of an egg.
2. Empty the contents of the egg, and dry the inside of the shell.
3.Tape three LEDs of the same color to a lithium coin battery.
4. Put a few pieces of cotton into the shell to diffuse the light and to keep the LEDs inside. Put the LEDs and the battery into the shell. Dim the room lights to get the full effect.

One day late last year, Bill Rulien decided he’d had enough of people boasting about how they had modified their golf carts with hotrod paint jobs or monster-truck tires. “I thought, I’m gonna build something that will say, ‘Well, top this.’ ”

On February 10, 2009, a U.S. and a Russian satellite collided 500 miles above Siberia, adding at least 2,000 chunks to the roughly 100 million pieces of debris currently orbiting Earth. These scraps of satellites, abandoned rocket parts, jettisoned fuel and flecks of paint travel between 7,000 and 18,000 miles an hour, colliding with increasing frequency, which could lead to a feedback loop known as the Kessler syndrome.
