A new type of cloth can guard against noxious gases and odors by trapping their molecules inside its fibers, according to Cornell University. A Cornell undergrad fashioned the cloth into protective head gear, seen here in a summery shade of turquoise.
The cloth is made of cellulose fibers and metal-organic framework molecules, crystalline compounds that form a porous structure. The pores can trap and store molecules of gas, serving as wearable filtration systems.
On July 2, 2007, Scott Showalter climbed into a manure pit on his Virginia farm to clear a blocked pipe. Moments later, he fainted and died. An employee of his went in to save him but was quickly overcome as well. One by one, his two daughters and wife followed, only to die trying to save the people who went before them.
Rats used for testing drugs and cosmetics might soon be replaced by lab-grown human lungs. “Microlungs” are lung cells harvested from humans and grown onto plastic scaffolding. A handful of drug companies are already testing the technique, which grows cells that mimic functioning lungs. It may one day help end the need for animal testing stages in drug development.
It's official: Santa showed up a little early this year. The unveiling of the Popular Science archives on Google was, last week, a very big deal. Our readers and fans can now search and browse over 136 years' worth of the future then and now whenever they damn well please.
Ever resourceful, PopSci DIY-ers are already doing what they do best. Instructables.com member TimAnderson created a gas mask using instructions in a December 1942 Popular Science Article. How awesome is that?
