Military and police higher-ups can now see just how many shots a particular weapon fired during the course of a battle or incident. The Register reports that a new black box device designed for rifles and submachine guns could report on ammo usage and weapon jamming, as well as who shot whom at what time.

Rockets are the tried and true workhorses for launching payloads into space. But that could change, if a physicist realizes his vision for a 1.1-kilometer-long (0.7 mi) gun that could fire cargo into low Earth orbit.

The new supergun concept could fire payloads of 450 kilograms (990 lbs) at more than 13,000 mph, according to John Hunter, a physicist who formerly worked at the Lawrence Livermore National Laboratory in California.

Scientific justice is just around the corner thanks to a new nanotechnology system that not only better captures DNA on guns, but attaches hard-to-remove, microscopic tags to the hands and clothing of criminals who fire their weapons. Developed in the U.K., the tags are a unique blend of naturally-occurring pollen, known for its extraordinary adhesive properties, and nanotechnology particles.
