News reports say that 11 of the 12 game balls used by the New England Patriots in their AFC championship game against the Indianapolis Colts were deflated, showing about 2 pounds per square inch (psi) less pressure than the 13 psi required by the rules, so it seems that the most bizarre sports scandal of recent memory is real. But there are still plenty of questions: why would a team deflate footballs? Could there be another explanation? And most importantly, what does physics tell us about all this?
When the guy in the cubicle next to you microwaves his tikka masala or tears open a bag of chips, your nose and ears perk up — food.

The havoc that Ebola is wreaking in West Africa cannot be understated. With a total of 21,200 people infected since March 2014, the disease is shredding the social fabric of Guinea, Sierra Leone, and Liberia, leaving 8,400 dead. People live in fear, afraid to shake others' hands. Survivors are shunned, and those suspected of carrying the disease are being physically assaulted in some regions. Schools are closed, and economies have been ravaged.
