Five-time champion Serena Williams reached her first Grand Slam quarter-final of 2014 at the US Open but Canadian poster girl Eugenie Bouchard, struggling in the heat and humidity, was knocked out. World number one Williams, the two-time defending champion, eased past world number 50 Kaia Kanepi 6-3, 6-3 on Monday for a fourth win over the Estonian and goes on to face fellow 32-year-old Flavia Pennetta of Italy in a clash of the two oldest remaining players in the draw. "It's my first quarter-final of the year at the majors -- at last I did it," said the American, who had fallen in the fourth round in Australia, the third round at Wimbledon and suffered a second round French Open exit. Seventh seeded Bouchard was at the centre of a medical drama on Louis Armstrong court when she had to have her blood pressure and temperature taken in her 7-6 (7/2), 6-4 defeat to Russian 17th seed Ekaterina Makarova.
Former champions Novak Djokovic and Andy Murray booked a tantalizing US Open quarter-final duel with straight-sets fourth-round victories. World number one and top seed Djokovic didn't let Philipp Kohlschreiber stand in the way of another Grand Slam last-eight appearance on Monday, defeating the 22nd seed from Germany 6-1, 7-5, 6-4 on another oppressively muggy New York day. Eighth-seeded Scot Murray advanced with a hard-fought 7-5, 7-5, 6-4 victory over ninth-seeded Jo-Wilfried Tsonga, avenging a loss to the Frenchman in the Toronto Masters last month. They are 2-2 in Grand Slam finals, including Murray's triumph over Djokovic in the 2012 final at Flushing Meadows for his first major crown.
The FBI and Apple were urgently investigating after an apparent massive hack of a cloud data service unleashed a torrent of intimate pictures of dozens of celebrities across the Internet. Anonymous posters to online message boards boasted of having nude images of scores of female stars including Oscar-winner Jennifer Lawrence and top model Kate Upton. Reports suggested hackers had "ripped" private images from Apple's iCloud online data storage, a potentially embarrassing -- and damaging -- breach for the California tech giant. "We take user privacy very seriously and are actively investigating this report," said Apple spokeswoman Natalie Kerris, the Re/code website reported.
