PRINCETON, N.J. - Princeton students couldn't claim to be uninformed yesterday. Volunteers for PVotes, a non-partisan, get-out-the-vote organization at the university, walked dorm-to-dorm to let students know where and how to vote in the day's New Jersey primary.

Philadelphia earned the nickname Killadelphia in the national media last year as 392 murders took place in the city. Now, new Police Commissioner Charles Ramsey is trying to change both the number and the nickname.

Several members of the Penn faculty and staff recently received a threatening e-mail, which claimed that the recipient was marked for death by an alleged hit man, whose contract could only be terminated if the recipient paid a certain amount of money.

Actor Woody Allen once quipped, "I don't want to achieve immortality through my work. I want to achieve it through not dying." His wish might just come true. Aubrey de Grey of Cambridge University, author of Mitochondrial Free Radical Theory of Aging and Ending Aging, spoke yesterday in Levine Hall about the possibility of indefinitely preventing aging.

NEW YORK - At Columbia University yesterday, students turned out in high numbers to support Illinois Sen. Barack Obama's run for the Democratic presidential nomination. But the showing was lighter for New York Sen. Hillary Clinton, even on her home turf. Students for Obama set up a phonebanking station on Barnard College's campus and made calls throughout the day.

Don't let anyone tell you student activism is dead. Students involved in last week's victory for AlliedBarton security guards at Temple would say they proved the contrary. The security company granted its Temple guards up to three days' paid sick leave after coming under pressure from a coalition of its employees, Temple students and local activists.

Despite living in China as a child, it wasn't until Zhi Geng returned as a study abroad student that she discovered her own jewel in the capital city: a small restaurant near the west gate of Beijing University that serves the most amazing chicken wings. For the Wharton and College senior, spending a semester in Beijing allowed her to reconnect with her cultural roots, which she had few memories of as a child.

A downtown performing arts venue is getting a public image boost from members of the Penn community. Students and professors are teaming up with the Kimmel Center for the Performing Arts this semester in an attempt to create a more vibrant and welcoming public space downtown.

Though 22 states will vote in Democratic primaries and caucuses today, at the end of the night, the Democratic nomination could still be anyone's game. After former North Carolina Sen. John Edwards withdrew his candidacy last week, the Democratic field narrowed to New York Sen.

Last week, Judith Hodara, the Senior Associate Director of MBA Admissions at Wharton, and her outside consulting stints raised a few eyebrows - within the Penn administration and the wider admissions community. Last Wednesday, Inside Higher Ed published an article that linked Hodara - along with two other senior admissions officials from Columbia University and the University of North Carolina - to the advisory board of AGOS Japan, a Tokyo-based consulting company that helps locals get into top United States MBA programs.

College Dean Dennis DeTurck often challenges math department colleagues to tell him when exactly he would need to know that 5/7 plus 3/5 equals 46/35. "The answer is never, except in a specifically mathematical context," DeTurck said. That's why he wants Americans to rethink how and when they teach fractions.

It was Friday, and it was time to feel good. Last week, outfitted with cushions and clementines, the Penn Women's Center kicked off Feel Good Fridays, a weekly program featuring free public workshops, with a seminar on nutrition led by local health counselor Jillian Bird.

As the number of general thefts in the Penn patrol zone continues to rise, the number of violent crimes has decreased in comparison to this time last year. Crime totals in the area this January remained steady compared to the same month last year, with 60 crimes reported in both 2007 and 2008.

The nation as a whole is getting older, but the process doesn't have to be painful. Penn researchers are investigating cures for a variety of neurodegenerative diseases to improve the quality of life for both patients and their caretakers. "Penn has traditionally had strengths in neuroscience and the strengths are not just in one department," said John Trojanowski, co-director of Penn's Institute on Aging and guest editor of a Neurosignals issue featuring Penn research on diseases like dementia, Parkinson's and Alzheimer's.

During junior year, everyone wants to know where you're studying abroad. But for around 75 percent of Penn's junior class each year, the answer is "nowhere." Whether for obligations on campus or to stay on-track with coursework, a majority of students have legitimate reasons for remaining in Philadelphia all four years.

The Grand Old Party might be able to celebrate a new nominee by tonight. Twenty-one states will vote today for the Republican presidential nomination and pressure could not be greater with over half of all delegates at stake. The Republican race has whittled down to four remaining candidates: John McCain, Mitt Romney, Mike Huckabee and Ron Paul.

He was featured in a documentary at the international Sundance Film Festival last month in Utah. Soon, his peers at Penn may be seeing him in theaters nationwide, even at next year's Academy Awards. College freshman Yoni Gruskin might be a rising movie star - but not for his acting skills.
