Nanotech Paint To Kill Bacteria

ColGraff points out reporting at Science News about the possibility of killing bacteria with paint. Scientists in the UK have found that high concentrations of titanium oxide nanoparticles in paint can kill bacteria by creating hydroxyl radicals when exposed to ordinary fluorescent light. Titanium dioxide is present in most white paint at concentrations of 30% or so, but not always at nanoparticle scale. The researchers found that an 80% concentration of TiO2 nanoparticles worked well to kill E. Coli bacteria. There is hope that the technique could be used against "superbugs," which are resistant to multiple antibiotics. A researcher not associated with the UK team pointed out the problem with developing products based on this idea: "[A]nything that survives and sticks around grows greater resistance... ultimately [antibiotic paint] will be its own worst enemy and the bacteria could grow to be even stronger."

    When I came home early from work one day, the air in my house was hot and humid. A distinctive scent of onion musk was in the air and I figured that my wife had just cooked me a meal of mexican food.

    How sweet of her!

    But, suddenly, I heard strange noises coming from down the hallway, from my bedroom. I heard the faint sound of female sighs and moans mixed in with a vibrant, low groaning much like that of a large dog or perhaps an ape.

    I walked down the hall and noticed that the farther I went, the stickier and stinkier the air became. The noises became louder and I was able to hear that it was my wife who was doing the moaning.

    A nervous sick feeling tightened my stomach into a huge knot as my brain was unable to comprehend what my senses were telling me.

    I entered into a trancelike state, stoically finishing the eternal journey down the lonely, hot hall. Next, I slowly twisted the doorknob and when I opened the door I saw...no...my beloved, pure-as-snow wife was FUCKING A GODDAMN
