California dreaming isn't over yet. Ten days after completing its West Coast spring trip, the Penn men's tennis team will take on California-Riverside at Lott courts today in the final match of the non-conference schedule. The Quakers are happy to return to Philadelphia and hope that home-court advantage will give them an edge over their West Coast foes.

Early Sunday morning at a house on 55th Street in West Philadelphia, the students of JAM for Philly - a community service and religious group comprised of Muslim and Jewish students - put aside their differences and picked up paint brushes to renovate the home for a family in need.

An innovative piece of BlackBerry technology developed by a group of engineering students at Yale University could add another dimension to campus safety. The free smartphone application called BScope Mobile was launched just over two weeks ago, and allows BlackBerrys to use raw GPS data to provide highly accurate information on the movements of the phone's owner.

In 2006, Robert Irvin had one of the best seasons for a Penn sophomore quarterback in the past half-century. Then he lost much of the next year to injury and would never again claim the top of the depth chart. But the coaching staff had never found a consistent replacement for him until late last season, when they were forced to turn to unknown sophomore Keiffer Garton, having literally run out of options.

"Philly Fight Night," an amateur boxing competition in February pitting Wharton MBA students against other Penn graduate students, raised $55,000 for the Boys & Girls Clubs of Philadelphia this year. Al Mollica, chief development officer of the Boys & Girls Clubs, said the clubs serve over 15,000 kids throughout the city, and "Philly Fight Night" is "one of the biggest sources of fundraising income that the organization has over the year" to support its programs - which include education and career development, health and life skills, athletics and recreation and arts and culture.

This year, most juniors and seniors will celebrate Hey Day without missing classes.

Doug Glanville put together one of the most successful baseball careers of any Ivy League athlete. After co-captaining Penn's 1991 league championship squad, he went on to hit .277 in nine seasons (1996-2004) patrolling centerfield for the Cubs, Phillies and Rangers.

Spring break was a much-welcome respite, more so than it's ever been for me in the past. That's because I spent most of January and February living in my suit, hustling for a summer internship in finance. The daily grind of information sessions, networking events, resume drops and interviews is a hallowed coming-of-age ritual for a Whartonite.

Deja vu. The members of the Penn softball team had seen it all too recently as the second game of their doubleheader against Monmouth ended Saturday. After a 1-0 loss in the first game, the Quakers fell to the Hawks by the same score - and in almost the same exact fashion - in the nightcap.

"Rusty" is the best way to describe the Penn women's golf team's performance this past weekend, according to coach Mark Anderson. "That's expected for the first tournament in the spring, especially coming from the northeast," Anderson said.

ST. LOUIS - For Rollie Peterkin, the March 19-21 NCAA Tournament was the same disappointment, just a different year. Just like in 2008, the Penn 125-pound wrestler advanced all the way to the round of 12 - the round just before All-American status is guaranteed - only to lose a close match and see his dreams of placing at nationals go up in smoke.

At its best, Penn baseball is a team with hitters who can knock the ball out of the park and pitchers with special stuff. At their worst, the Quakers are an immature team prone to inconsistency at the plate and on the mound. During its first four-game series of the season, both sides showed up.

Tiredness, rewards, status: it's all in the head, three research studies say. Michael Halassa, a doctoral student in the School of Medicine's neuroscience department, and Philip Haydon, Halassa's former mentor and a professor at Tufts University, collaborated to study astrocyte cells in the brain and their impact on animal sleep behavior.

This Wednesday, the Graduate and Professional School Assembly will vote to pass a proposal that aims to establish a "campus climate survey" that polls student perceptions about campus education and student life. While GAPSA has polled students in the past, the group aims to involve the administration in the process to ensure its repetition and longevity.

A new study by Penn's School of Medicine developed a test to detect Alzheimer's disease in patients in its early stages, before the disease's symptoms start to manifest. Led by Leslie Shaw, the co-director of the Penn Alzheimer's Disease Neuroimaging Initiative Biomarker Core, the study was published online in the journal Annals of Neurology this month.

Looking for a bite after your party or in the middle of your all-nighter? Sadly, on Penn's campus, you will soon be out of luck.
