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.
The New York Times just reported the death of a man who saved -- and contines to save -- many lives: Dr. Earl Wood, one of the inventors of the G-suit. The G-suit, created in the 1940s, is a pressurized outfit that keeps pilots from losing consciousness during fast turns and dives. Military pilots started using it during World War II to remain alert and prevent crashes, and they (and astronauts) still use similar suits today.
