A tiny biochip has the potential to quickly determine whether or not a person has been exposed to dangerous doses of radiation, according to the Lawrence Berkeley National Laboratory, which helped develop the device. Though further work on the chip is necessary, the eventual technology is expected to quickly screen exposed persons in the event of a radiological catastrophe.
All of us have this one problem in common. Off course it's a problem in varying degrees. Some have a mini one, others have a herculean one. The problem is offensive socks. But how do socks get to be such a problem anyway? Well, the good news is that feet do not naturally have any odor glands.
The human body is sensitive to its environment. We have a range within which we feel comfortable - a certain temperature range; a certain illumination range, a certain level of sound, pressure and even humidity. Alter any of this too much or for too long and the body will protest. In a dry environment, like an air-conditioned office, the moisture from our body is extracted to the environment and our skin dries.
Between carbon dioxide, dust, and sulfur dioxide, the air around us can get pretty polluted. In New York we emit as much as 149,000 metric tons of carbon dioxide in a day. What about dust? We know there's a lot of that too. What about sulfur dioxide, well there's about 60,000 tons of that a year in New York.
