On one of the nicest days this semester, College Green was filled with guitar players, tie-dyed T-shirts and a solar-powered grill - all to celebrate the environment. Friday was Penn Environmental Group's fourth Green Fest, a twice-yearly celebration of sustainability and green alternatives for Penn students.

PRINCETON, N.J. - Sophomore pitcher Robbie Seymour entered the weekend giving up over a run every inning, but Penn coach John Cole was still trying to turn him into a starter. Cole reaped the benefits of his persistence yesterday, and the Quakers stuck around in the Ivy League title race a bit longer as a result.

Between farmers' markets, sword fights, local sports leagues and flea markets, Clark Park is constantly abuzz with activity. This summer, a local theater company will provide even more action for students staying on campus with its third-annual free show in the park.

Two wrongs don't make a right. It's important to remember that while the Recording Industry Association of America has every right to go after individuals for copyright infringement, it can't break the rules while doing so. The RIAA usually identifies IP addresses where illegal downloading is taking place and asks universities to forward pre-litigation letters to the students with those addresses.

Yankee stadium was packed yesterday afternoon - but not with the usual baseball fans. Almost 60,000 people from all over the country gathered to attend a mass led by Pope Benedict XVI during his first trip to the United States as leader of the Roman Catholic Church.

The Provost, Council of Undergraduate Deans and the Office of College Houses and Academic Services announced last week that Neil Shubin's Your Inner Fish: A Journey Into the 3.5 Billion-Year History of the Human Body will be the reading for the 2008-2009 Penn Reading Project.

We've long been told to drink eight glasses of water a day - but that may not be necessary. Penn researchers Stanley Goldfarb and Dan Negoianu reviewed research on water intake and concluded that there is no reliable scientific data to support the idea that drinking those eight glasses makes a person healthier.

The governor and mayor of Philadelphia aren't the only political leaders endorsing a candidate for the upcoming presidential primary. Last week, student government leaders at several Philadelphia universities, including Penn, Temple and Villanova Universities and Haverford College, jointly authored a letter endorsing Senator Barack Obama as the Democratic candidate for president.

Nineteen-seventy-six was the last time the Pennsylvania primary was relevant in a Presidential election. For over 30 years, Penn students have not had a meaningful say in the Democratic Party's nominee for president. This year we have our chance. The 2008 Presidential election is the most important election we have ever seen.

It was another disappointing weekend for the Penn softball team, but at least it could be proud of something: The Quakers toppled previous Ivy undefeated Princeton, 7-2, in game one of yesterday's doubleheader at Princeton, N.J. The other three games were undoubtedly frustrating for the Red and Blue, as they lost them by just five runs combined.

After graduation, most seniors are looking forward to stepping out into the real world alone. But this summer a group of six seniors will travel to New Orleans to try to make a difference - together. Inspired by an Urban Studies class that explores various models for revitalizing impoverished communities around the world, College senior Yasmin Radjy decided she wanted to turn her classroom lessons into reality down in the Big Easy.

A small fire broke out in Rodin College House Friday evening, causing no injuries but forcing residents to evacuate. A plastic container that was too close to the stove top while students were cooking caused the blaze, Rodin House Dean Ken Grcich said. The plastic caught on fire at about 8 p.

Singing, laughing and a customary Gatorade dousing of coaches marked the end of the Penn women's lacrosse team's Ivy League season. The Quakers coasted past Brown Saturday, 12-5, to collect their second consecutive Ivy title. But before Coach Karin Brower's clothes could even dry, the Quakers (12-1, 7-0) had their sights set on revenge and the Division I championship.

Three out of 51. That's Penn's record against rival Princeton since 1982, the year that the teams began playing one another. If there was ever a time to begin making up such a monstrous deficit, this weekend's back-to-back doubleheader against the Tigers would be it.

Well, the hard part is over now. The No. 6 Penn women's lacrosse team upset its chief Ivy rival in No. 2 Princeton to clinch at least a share of its second-consecutive Ivy title. All that's left for the Quakers is beating middling Brown tomorrow at Franklin Field to win the regular-season championship outright.

As is often the case with politicians, Pennsylvania House speaker Dennis O'Brien has been accused of occasionally practicing contradictory politics. His desire to keep criminals from going unpunished is unmistakable, as is his concern for the safety and well-being of Pa.
