With the help of wireless sensors, Stanford researchers confirmed what most of us suspected. When it comes to infectious viruses, human beings are toast.

The devices tracked how often people came within the infection-spreading range of other individuals during a typical height-of-flu-season January day. Every teacher, student and staff member at the school carried a credit card-size TelosB device that sent and received signals every 20 seconds.
