Philippines Senator Benigno “Noynoy” Aquino III announce his candidacy in Manila on September 9.

Philippines Sen. Benigno “Noynoy” Aquino III announced he will run for president Wednesday, a month after the death of his late mother, the popular former President Corazon Aquino.

Philippines Senator Benigno “Noynoy” Aquino III announce his candidacy in Manila on September 9.

“I’m accepting the challenge to lead this fight,” said Noynoy Aquino, the state-run Philippines News Agency (PNA) reported.

Aquino, 49, is the only son of Corazon Aquino, who died on August 1, and the late Benigno “Ninoy” Aquino, a senator who opposed dictator Ferdinand Marcos and was assassinated in 1983 on returning home from exile in the United States.

Noynoy Aquino said his mother’s supporters had urged him to make a run for the presidency in next May’s elections. He said he would continue the fight started by his parents to promote democracy in the Philippines.

At least one lawmaker was critical of Aquino’s run, PNA said.

Rep. Pastor Alcover Jr. said the media has deceived the public by presenting Aquino as the man who can save the country.

“We need a hardworking president,” Alcover said. “But the problem is, Noynoy has a dismal performance as congressman for nine years and as senator for three years. Do we want more of his laziness?”

President s term ends in 2010. Under Philippine law, she cannot run again.

Arroyo first took office in 2001. Since then, she has survived several impeachment attempts and periodic rumors of coups. She won re-election in 2004, though opposition parties called into question the legitimacy of that race.

Liverpool fan Michael Shields has been pardoned by Justice Secretary Jack Straw.

The 22-year-old, who is serving a 10-year sentence for the attempted murder of a barman in Bulgaria, is set to leave prison later.

He was jailed in 2005 for the attack, which took place after his team’s win in the 2005 Champions League final.

His parents, Michael Snr and Maria, have campaigned for his release since he was convicted.

In a statement, Mr Straw said that during the last meeting with the Shields family on 28 August “important new evidence came to light”.

He was told about a visit by two members of the Shields family to the home of another man alleged to be responsible for the crime.

He said: “I was told that in the course of the visit that man made an oral confession to the crime in front of several other people.

“When looked at alongside all the previously available evidence, (it) has now satisfied me that Mr Shields meets the high test set by the court.”

Mr Straw added that he believed Mr Shields to be “morally and technically innocent”.

The 22-year-old’s solicitor, John Wheate, said the jailed fan was “absolutely ecstatic” when he was given the news earlier.

He said his client was told by the prison governor that he would be a free man at 0930 BST and his family were informed by Mr Straw over the telephone.

Mr Wheate said: “I don’t know if Michael has been released yet but I can confirm he has been pardoned and will be released today.

“At first he couldn’t believe it after all these years and knock-backs.

“But now he is absolutely ecstatic and so are his family.”

The pardon follows a campaign by the Shields family, MPs, clergymen, Liverpool players and others who believe he is innocent.

Louise Ellman, Labour MP for Liverpool Riverside, who has been campaigning for Mr Shields’ release since he was convicted, said: “I am overjoyed at Jack Straw’s decision.

“Michael has suffered a gross miscarriage of justice, incarcerated for four years for a crime he did not commit and for which another man has confessed.

“I pay tribute to Michael’s family and the people of Liverpool for their remarkable courage and persistence.”

Mrs Ellman added: “Jack Straw has brought justice to an innocent young man.

“This is a day for celebration.”

Shel Israel is not the kind of person you’d expect to find on Twitter all day. He’s 65.

Shel Israel, author of a new book on Twitter. He says the micro-blogging service changed his life.

But Israel has been using the micro-blogging service longer than most. In fact, he gave up his lifelong habit of reading the newspaper every day about four years ago and turned exclusively to social media.

He now knows how to use Twitter, how not to use it, and how to benefit from it, and he says Twitter has changed his life.

The social-media journalist and public speaker is the author of a new book, “Twitterville: How Businesses Can Thrive in the New Global Neighborhoods.” The book shows how Twitter flattens geographical boundaries and helps people connect with others around the world who share their interests.

To Israel, it’s the mundane details of one’s life, shared through tweets and status updates, that matter. He believes that tweeting about what you had for lunch can actually help build a meaningful personal or business relationship.

Israel also says that who you follow on Twitter is much more important than the number of people who follow you. That’s because the people you follow become “your newspaper — the way you get the information that you see, that you digest, and that you use.”

Here is an edited version of the conversation.

US researchers have pinned down new differences in the brain chemistry of people with attention deficit hyperactivity disorder (ADHD).

They found ADHD patients lack key proteins which allow them to experience a sense of reward and motivation.

The Brookhaven National Laboratory study appears in the Journal of the American Medical Association.

It is hoped it could help in the design of new ways to combat the condition.

Previous research looking at the brains of people with ADHD had uncovered differences in areas controlling attention and hyperactivity.

But this study suggests ADHD has a profound impact elsewhere in the brain too.

Researcher Dr Nora Volkow said: “These deficits in the brain’s reward system may help explain clinical symptoms of ADHD, including inattention and reduced motivation, as well as the propensity for complications such as drug abuse and obesity among ADHD patients.”

The researchers compared brain scans of 53 adult ADHD patients who had never received treatment with those from 44 people who did not have the condition.

All of the participants had been carefully screened to eliminate factors which could potentially skew the results.

Third seed Rafael Nadal of Spain overcame a first set tiebreaker loss to cruise through the next three sets and beat Frenchman Gael Monfils 6-7 (3-7 6-3 6-1 6-3 in the U.S. Open fourth round.

Spaniard Rafael Nadal returns to France’s Gael Monfils at the U.S. Open in New York on Tuesday.

Nadal, the six-time grand slam winner and reigning Australian Open champion, has been coming off a two-month lay-off due to knee tendinitis, a break that kept him from defending his 2008 Wimbledon crown.

He also showed no signs of the stomach injury which troubled him in the previous round, but served conservatively with a maximum speeed of 119 mph (192 kph) compared with 131 mph (211 kph) by Monfils.

But Nadal had no double faults against four for his opponent and showed signs that he is coming back to his best.

“I am improving every day. After a month and a half or two months, it is not easy coming back,” Nadal told reporters.

Nadal advances to a quarterfinal matchup against 11th seed Chilean Fernando Gonzalez, who edged seventh seed Jo-Wilfried Tsonga of France 3-6 6-3 7-6 (7-3) 6-4.

Earlier, in a massive fourth-round upset, second seed and last year’s runner-up Andy Murray lost in straight sets to Croatian 16th seed Marin Cilic.

Briton Murray, who was seeded to face holder Roger Federer in a repeat of last year’s Flushing Meadows final, looked lackluster throughout the match as Cilic comfortably reached his first grand slam quarterfinal with a 7-5 6-2 6-2 victory in two hours and eight minutes.

Cilic will now face Argentine Juan Martin Del Potro for a place in the semifinals, after the sixth seed secured a comfortable 6-3 6-3 6-3 victory over Spanish 24th seed Juan Carlos Ferrero.

“I played very well and Andy was missing a lot,” Cilic told reporters. “I don’t think he was playing his best. It feels amazing to reach the quarters,” added the 20-year-old, who is the youngest player in the world’s top 20.

Murray had beaten Cilic in their three prior meetings, most recently in the fourth round of this year’s French Open, but looked off-form from the start.

The Briton had come back from two sets to love down at the same stage of last year’s tournament to beat Austrian Jurgen Melzer en route to his first grand slam final.

But he only won four games out of the last 18 to slump out on his favorite hard-court surface, refusing to use a wrist injury as an excuse for his shattering exit.
