News Portal, latest news from around the world.

(CNN) -- England's Nick Dougherty could salvage a disastrous season as he led the European Masters after the first round but has major winners Rory McIlroy and Martin Kaymer as his nearest challengers at Crans-sur-Sierre.

Dougherty, rated one of the most promising golfers on the European Tour, has missed 21 cuts in a row to slip to 791st in the world rankings, but refound his form Thursday with an eight-under 63 in the Swiss Alps.

U.S. Open champion McIlroy and 2010 PGA Champion Kaymer were two shots back after 65s in the morning rounds, sharing second with England's Gary Boyd and Korean Lee Sung.

In a star-studded line-up, world number two and his stablemate and British Open champion Darren Clarke were tied for eighth after 67s. In an unusual twist, the 29-year-old Dougherty was interviewed by his golf presenter wife Diane after his round and admitted he had not been easy to live with during his unexpected slump.

(CNN) -- Defending champion Usain Bolt was sensationally disqualified for a false start in the men's 100-meter final at the world athletics championships in Daegu, South Korea, allowing fellow-Jamaican Yohan Blake to collect an unexpected gold medal.

Bolt has dominated men's sprinting since winning 100-meter and 200-meter gold at the Beijing Olympics in 2008, achieving the same feat at the world championships in Berlin the following year -- smashing the world record in the process.

And although he had not entered this year's worlds in top form, the absence through injury of rivals Asafa Powell and Tyson Gay meant he was the hot favorite to retain the first part of the sprint double.

However, the 25-year-old fell foul of the current false start rules, which state that any athlete who jumps the gun is immediately disqualified.
