Item 1: JK Rowling, the Harry Potter author, has signed a publishing deal with Little Brown, to
release her first ever novel for adults. The deal means that Rowling's long-standing relationship with
Bloomsbury, the London-based publisher that launched the Harry Potter books, has come to an end,
at least in terms of new works by the author. Rowling, who is worth an estimated ?530 million, said
that the new novel will be nothing like the Harry Potter series, which sold over 30 million copies in the
UK alone. She said that with the move from children's to adult fiction, a move to a new publisher
seemed like a logical step. [More]
Item 2: China's hurdler Liu Xiang was disqualified Thursday at the Stockholm indoor athletics
tournament due to false start, giving his rival Dayron Robles of Cuba an easy win of 7.66 seconds. Liu
was not willing to explain the reason of his false start, but he told Xinhua that it was not related to his
foot injury. Another Cuban Orlando Ortega followed in 7.68 seconds and Balazs Baji of Hungary stood
third in 7.70 seconds. Last Saturday, Liu won the men's 60m hurdle final in 7.41 seconds at the
Birmingham indoor tournament, setting a new Asian record. He said Wednesday that he hoped to have
an even better performance than he did in Birmingham at the Stockholm indoor tournament. [More]
Item 3: Former NBA star and current Bobcats owner Michael Jordan filed suit in a Chinese court
against Qiaodan Sports Company Limited, a sportswear and footwear manufacturer, for the use of his
name without permission. Jordan says "This complaint is not about money, it's about principle and
protecting my name." The Chinese company has registered and uses the name "Qiaodan". Jordan has
been known in China since he gained widespread popularity in the mid-1980s. [More]
Item 4: A commuter train crashed at a busy central station in Buenos Aires on Wednesday, killing
49 passengers and injuring more than 600 people, the deadliest in a series of train accidents in Argentina
over the past years. The train crashed at about 8:30 a.m. at its final stop at the Once Station, not far from
downtown Buenos Aires. The train was carrying more than 800 passengers and traveling at an estimated
16 miles per hour when it entered the station, slamming into the barrier of the platform, destroying the
engine. [More]
