Most of the flavoring in gum is due to the sugar or other sweetener it contains. As gum is chewed, the sugar dissolves and is swallowed. After a piece of gum loses its flavor, it can be left to dry at room temperature and then the difference between its initial (unchewed) mass and its chewed mass can be used to calculate the percentage of sugar in the gum. This demonstration experiment is used to generate new questions about gums and their ingredients, and students can then design and execute new experiments based on their own questions.

Twenty percent of all premature babies contract serious infections while in the hospital. By harnessing millions of heartbeat measurements from the ICU each day, Dr. Carolyn McGregor found she could detect a baby's infection at least one day before it became symptomatic, giving physicians a potential 24-hour jump on treating and beating the bacteria. McGregor's team, called Project Artemis, is still in the process of publishing and confirming the findings, but they hope that ICUs around the world will soon begin using their data as an early-warning system, enabling babies to begin receiving lifesaving treatments before it's too late.
