It’s getting to be that time of the year when classes are finally in full swing, first papers are due, and hours spent in bed are slowly trickling away. If the readjustment to the grind is taking its toll and you’re getting grilled for yawning during that 50-minute lecture, Andrew Gallup, a researcher in Princeton’s EEB department, has a new explanation you can try on your professor.
In a study published earlier this month in Frontiers of Evolutionary Neuroscience, Gallup found that that the purpose of a yawn is to cool the brain. People were shown to be more likely to yawn in winter than summer, and Gallup thinks this might be because an overheated brain gets no relief from taking in warmer air.
Gallup said having an overheated brain could cause feelings of drowsiness, explaining why we also yawn when we are sleepy.
“When you are warmer you are more likely to feel tired. At night when you are about to sleep your body temperature is at its highest point of the day,” he said.

Most would argue that Forbes is at once the most hated and most beloved of the residential colleges. Depending on who you talk to, Forbes is either that sad, cinder-blocked building in a distant zip code or, alternatively, the best thing that ever happened to them. For every mainland critic who argues that Forbes is socially removed from the main-campus scene, there are steadfast Forbesians who contend that their residential remoteness actually forges a more “close-knit community.” After two years of living in the 08540, it’s become clear to me that, polarized views aside, Forbes is what you make of it. Here are the facts—we’ll let you be the final judge.

There’s something about this bleak weather that makes the idea of shopping for Lawnparties outfits extremely appealing. That’s how I ended up at the brand-new Lilly Pulitzer store in Palmer Square, which opened its doors last week. I chatted with Ted, the manager, and got down to the nitty-gritty of paisley, parties, and Pulitzer.
And, yes — those are life-size Taylor Lautner and Robert Pattinson cutouts donning their holiday best.
