Christina Khosravi is no stranger to walk-off wins. She did, after all, cap an extra-inning affair with a game-ending knock on April 2 against La Salle. Yesterday, however, Khosravi's mere presence earned Penn a last-inning win. With freshman Alisha Prystowsky on second and no outs in a 3-3 game, Drexel pitcher Ellen Boundy opted to intentionally walk the Quakers' slugging shortstop.

Adrian Thomas doesn't have a particular affinity for stealing bases. In fact, there are six Penn players who have swiped more bags than the team's newly anointed leadoff man.

While a quarterback's pads won't make his throws more accurate and a point guard's shorts won't improve his jump shot, a swimmer's suit can make the difference in a race.

Are you reading this in a class that was so full on the first day you couldn't get a seat, but now it's as empty as your brain watching a Rock of Love Marathon? All those empty seats - I know you're thinking the same thing I am - who added all those extra chairs? Apparently, no one did.

To many schools with less-than-rigorous threat assessment systems, the past year's spate of school shootings have been a wake-up call.

Of the three candidates, only Senator Hillary Clinton has actually promised to end the war. The war on science, that is. Did you know we're in the middle of a war on science? We are. And it's being fought on many fronts. There are life-science researchers at Universities and the National Institutes of Health whose research could benefit from access to embryonic stem cells.

Every year, there are pre-season workouts, and then there is the pre-season meeting. The captains and coaches of Penn men's swimming sit down and lay out the rules for the upcoming season. How many practices can you miss? Can you drink two or three days in advance of a meet? But 2006 was different.

Following a two-hour search, the man suspected of shooting a constable and one other person yesterday in Yeadon was arrested in West Philadelphia. Tamarr Minor, 21, was arrested by Philadelphia police for the shooting, according to Philadelphia Police Lt.
