Don’t Let the Bedbugs Bite
It’s the middle of the night, and you and your bed-partner are wide-awake running your hands over each other’s bodies. No, it’s not what it sounds like. You’ve got bedbugs. Bedbugs have recently reinvaded American cities like New York, hiding in the tiny folds of mattresses and even cracks in walls, causing itching, redness and ultimately insomnia. Now scientists, publishing a new paper in the Journal of Medical Entomology, have done some intricate genetic detective work to find out how the critters have evolved a strong resistance to the insecticides used against them.

Invisible Bullet-Tagging Technology Could Deter Criminals
Gun-slinging evil-doers beware. 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.
8.5.2008 at 04:01pm - Comment by jrimsa75There is always Chris Rock's suggestion: solid gold bullets that cost $5000 each. Nobody's going to spray them randomly at that price. Seriously though, gun control isn't going to solve anything and the science behind identifying and matching a gun to a bullet is pretty well proven already, so I don't see what this provides.

The Buzz About Serial Killers
Bumblebees are being used to help capture serial killers -- and not by being trained to find and sting the culprits. Researchers have found that by analyzing a bee's geographic pattern as it goes around poking into flowers, they can deduce where the bee lives.
7.31.2008 at 03:38pm - Comment by jrimsa75Once again, we're focusing on catching a killer by waiting for them to kill and then track a pattern. A recognizable pattern doesn't often surface until many people are already dead. That's nothing new. I want police to "protect and serve" as in, PROTECT me, prior to my death. Finding my killer is not protection and does me, the victim, little good. What police actually do is revenge or justice, but it's not protection.

The Science of Superheroes
Spiderman, Batman, the Fantastic Four, Ironman—seems like every time we go to the movies, there's some guy in a unitard saving the world with acts of unnatural physics. We realize that these are works of fantasy, so we don't get too upset when the science portrayed in them comes from some alternative universe.
2.1.2008 at 11:09am - Comment by jrimsa75In the movie "DareDevil", a blind mand with ultra-powerful hearing fights evil. Here's the problem as I see it: He dodges bullets by listening to the sound of their coming, but since bullets travel faster than sound, he'd easily be shot before he ever heard anything.
