Health Scare of the Day: Quantum Dots
Health risks for the 21st century worker keep getting weirder. Researchers at North Carolina State University have found that quantum dots—nanoparticles made of semiconducting crystals that emit light when stimulated at certain wavelengths—can penetrate skin through abrasions.

Granted, some dangers we have created for ourselves, but many more have existed since forever, and we are just now becoming aware of it. Being unaware of it may make you sleep better at night, but does nothing to protect you from such dangers. I'll take knowledge any day.

The Breakdown: Can YOU Bend a Bullet?
7.6.2008 at 10:01am - Comment by oddflaskIt comes down to two main points: 1. To deflect the trajectory of the bullet, there needs to be some sort of force applied to the bullet while it is in flight. The Magnus Force is one such factor (the same thing that makes curveballs curve) but has negligible effect on the bullet in real life (a few millimeters). 2. Screwing around with the GUN itself will NOT affect the bullet's path after it has left the gun. It's a fun idea brought to life in a movie, but like so many things in movies, it isn't realistic at all.
