Ndamukong Suh should win the Heisman trophy, but he probably won't. Even after manhandling a fellow Heisman finalist in the Big 12 Championship game (see above), that may not be enough to push him over the top. The Heisman Trophy is essentially an offensive player award.

A chemistry student in the Ukraine was found dead with his jaw blown off by what is believed to be exploding chewing gum, according to reports.
The student apparently had a bizarre habit of chewing gum after dipping it into citric acid, Russian news agency Ria Novosti said.
Officers found both citric acid packets and a similar-looking unidentified substance, believed to be some kind of explosive material, on a table near the body, the agency continued.
Investigators suspect that the student simply confused the packets and put gum covered with explosive material into his mouth.

A 21.0 cm3 piece of dry ice is placed into a sealed 5.0 L container at STP. The dry ice is allowed to sublime while the temperature is held constant at 0°C. The container also contains 12.7 grams of sodium hydroxide. Sodium hydroxide reacts with carbon dioxide to form solid sodium carbonate and liquid water. What will the volume of the dry ice be when the pressure in the container is 2.5 atm? The density of dry ice is 1.5 g/cm3. Assume the volume of the container is 5.0L.
