In the wake of the Boston Marathon bombings, marathon organizers worldwide are examining their security arrangements, mindful that the very nature of the courses pose challenges perhaps unrivaled by any other sporting event. “It would be impossible to have security and police on every part of the race. There is no way to screen people who are watching it,” says Jeremy Jordan, an associate professor and director of Temple’s Sport Industry Research Center. “It is very uncontrolled.”

In advanced emphysema, the lungs become progressively enlarged. Researchers have long tried to find ways to reduce lung volume and improve airflow without risky surgery. Now, three promising techniques are in or near clinical testing at Temple University and other medical centers. "They all have pluses and minuses," said Temple pulmonologist Gerard J. Criner, a leading emphysema researcher. "I foresee a day where a patient would have several of these techniques, based on their anatomy."
