LONDON (AP)-South African runner Caster Semenya has been ordered to undergo a gender verification test, to prove she rightfully won the gold medal in the women's 800 meters at the world championships in Berlin on Wednesday.

Proving one's gender isn't always so easy. Aside from the obvious physical signs, chromosomes usually determine whether a person is male or female. Males are born with XY chromosomes while females have two X chromosomes.

About 1 percent of people are born with some kind of sexual ambiguity, sometimes referred to as intersexuality. These people may have the physical characteristics of both genders, a chromosomal disorder, or simply have ambiguous features. People who have both male and female organs are hermaphrodites.

Until 1999, the International Olympic Committee analyzed chromosomes from saliva samples to confirm the gender of female competitors and prevent men from masquerading as women. Other sports organizations have called the tests unreliable. The tests were scrapped before the 2000 Sydney Games.

WASHINGTON (AP)-Longtime Philadelphia Phillies broadcaster Harry Kalas, who punctuated innumerable home runs with his "Outta Here!" call, died Monday after being found in the broadcast booth before a game against the Washington Nationals. He was 73.

"We lost our voice today," team president David Montgomery said, his voice cracking. "He has loved our game and made just a tremendous contribution to our sport and certainly to our organization."

Kalas was found by the Phillies director of broadcasting at about 12:30 p.m. and taken to a local hospital, Montgomery said.

Kalas had surgery earlier this year for an undisclosed ailment that the team characterized as minor. He looked somewhat drawn last week as the Phillies opened the season at home.

Kalas joined the Phillies in 1971. Before that, he was an original member of the Houston Astros' broadcast team from 1965-70. He also did voiceover work for NFL Films and for commercials.

WASHINGTON - President Barack Obama declared Friday that the slumping economy has begun to show "glimmers of hope," but cautioned that it remains severely stressed and will require lots more work to turn it around.

Once criticized for talking too pessimistically about the economy, Obama is highlighting the positive.

"We're starting to see glimmers of hope across the economy," the president said after a White House meeting with his economic team, including Treasury Secretary Timothy Geithner and top economic adviser Larry Summers. Federal Reserve Chairman Ben Bernanke also participated in the session.

Obama echoed Summers' prediction a day earlier that the "sense of a ball falling off a table" would end in a few months.

States in which wallets are hit hardest.
In early April, fears of IRS tax men are warranted, but in many places it's the state government that residents should be worried about.

Take Vermont. It levies the nation's largest tax burden on individuals. Ask anyone living there if the green mountains, popular ski slopes and quaint bed and breakfasts are enough to soften the blow of $3,861 per person kicked up annually to the state government. You'll likely get a lot of "nos."

"The news is true. We are expecting a baby girl in April and we are ecstatic!" Trista told Access at the time.

And while the couple waited to find out the sex of their first child until he was born, she added that this time around, they wanted to know ahead of time.

"We didn't find out that Max was a boy until he arrived, but decided to spoil the surprise this time," she joked.

And both parents are elated to add a baby girl to their growing family.

"Although we would've been just as happy with a second boy, we are very much looking forward to giving Max a little sister!" Trista said.

Trista and Ryan, a firefighter, met on ABC's "The Bachelorette" in 2002 after Trista was the runner-up on "The Bachelor" in 2001.

SOUTH BEND, Ind. - Jimmy Carter came to Notre Dame in 1977. So did Ronald Reagan in 1981 and George W. Bush in 2001.

The University of Notre Dame has a tradition of inviting new presidents to speak at graduation. But this year's selection of President Barack Obama has been met by a barrage of criticism that has left some students fearing their commencement ceremony will turn into a circus.

Many Catholics are angered by Obama's planned appearance at the May 17 ceremony because of his decisions to provide federal funding for embryonic stem cell research and international family planning groups that provide abortions or educate about the procedure.

It sounds like something out of the pages of The Weekly World News, right next to an alien abduction story: Paralyzed California man bit by brown recluse spider walks again. Only it was reported for real last week on CNN, ABC, NBC and CBS.

Yes, a miracle - a miracle this could make the evening news, for this was a phenomenally poorly reported story bereft of the simplest of fact-checking. Of the three basic facts reported by these apparently professional journalists - paralyzed man, brown recluse spider, and walking - two are surely false.

Yet more than just another example of lousy broadcast journalism, such stories bring false hopes and even danger to those desperate enough to experiment with venom to cure their paralysis.

BAGHDAD - A suicide bomber struck a tent filled Monday with Kurdish funeral mourners, unleashing a huge fireball that killed at least 23 people in a northern town where Kurds and Arabs are competing for power. Also Monday, Turkey's visiting president pressed the Iraqi government to crack down on Kurdish rebels who stage cross-border raids into Turkish territory from sanctuaries in northern Iraq.

The provincial security office said 23 people were killed and 34 wounded in the suicide attack in the town of Jalula some 80 miles (120 kilometers) northeast of Baghdad.

A member of the provincial security committee, Amir Rifaat, said 24 people were killed and 28 wounded. The difference could not be immediately reconciled.

Karim Khudadat, whose father was being mourned, said he was receiving visitors when the bomber struck.

"I was with my relatives outside the tent receiving people who came to offer condolences when suddenly the explosion took place," Khudadat said. "Suddenly a huge flame engulfed the tent and I was wounded in my head and legs."

Elsewhere, eight people were killed and 10 wounded in a bombing near a bus stop west of Baghdad, and a policeman died and eight people were wounded in a suicide blast at a market in the northern town of Tal Afar.

PHILADELPHIA (AP)-A former NFL quarterback who failed to show for sentencing on drunken driving charges nearly four years ago was killed in a car crash in Greece, authorities said, leaving behind an unsolved mystery involving two suspicious fires and years spent on the lam.

The State Department used fingerprints to determine that the victim of Saturday's crash was William "Jeff" Komlo, according to Jim Vito, Chester County's acting chief detective. Vito said he was initially skeptical, concerned because of Komlo's history that he might have faked his own death.
