Laser Weapon Shoots Down Airplanes In Test 627

airshowfan writes "Boeing's directed-energy weapons (a.k.a. frickin' laser beams) have been getting some attention lately. The Advanced Tactical Laser (ATL) is a C-130 that famously burned a hole through a car's hood, and the YAL-1 AirBorne Laser is a 747 that shoots a laser from its nose that is powerful enough to bring down an ICBM. But even cooler is the Mobile Active Targeting Resource for Integrated eXperiments (MATRIX), a laser that is mounted on a truck (which probably costs less than a 747, but who knows) and that can shoot down small aircraft, as shown in the picture on this article. (The Laser Avenger supposedly also has this capability). We live in the future!"

Mercury May Have Molten Hot Magma at its Core 120

mattatwork writes "According to ScienceDaily, NASA has come to the conclusion that the planet Mercury may have a molten core after all, based on high-precision planetary radar readings. You may (or may not) remember the Mariner 10 probe making 3 passes by Mercury between March 29th, 1974, September 21st 1974 and March 16, 1975."
