Washington, Oct 30 : Data from a worldwide NASA-funded measurement network has shown that the greenhouse gas methane is on the rise again, after a decade long period of stability.

Methane levels in the atmosphere have more than tripled since pre-industrial times, accounting for around one-fifth of the human contribution to greenhouse gas-driven global warming.

Until recently, the leveling off of methane levels had suggested that the rate of its emission from Earth''s surface was being approximately balanced by the rate of its destruction in the atmosphere.

However, according to the research, the balance has been upset since early 2007.

Kabul - A suicide bomber detonated his explosive-filled vest inside a ministry in the centre of Kabul Thursday morning, causing up to five casualties, an interior ministry spokesman said.

The bomber entered inside the Ministry of Information and Culture in a busy area in the heart of city, Zemarai Bashary, interior ministry spokesman told Deutsche Presse-Agentur dpa.

"So far we can confirm that five people were killed or wounded," he said, adding that the number of casualties "might go up as we are still helping with evacuation."

London - Harry Redknapp has been Tottenham Hotspur manager less that a week, but already he has inspired them to their first victory of the season, and an astonishing comeback from 4-2 down to draw against Arsenal in the north London derby.

On Saturday he will be hoping for an even bigger surprise as his side face the league leaders Liverpool at White Hart Lane.

It may be bottom against top, but given Spurs' new-found confidence, this is far from a foregone conclusion.

It's going to be a long season, but there was a great atmosphere in that dressing room," Redknapp said.

"I've tried to make them believe in themselves. There's ability in the squad. Bring on Liverpool. We'll give them a good go on Saturday.

Madrid - Villarreal can hardly wait for Saturday to come.

That's when they will have the chance to put their awful recent form behind them, away to lowly Athletic Bilbao.

The normally solid Villarreal defence began to show signs of vulnerability in last week's 6-3 defeat of Euro minnows Aalborg. Sunday saw the "Yellow Submarine" shipping water, when Atletico Madrid forced a bizarre 4-4 draw in El Madrigal.

And the submarine was sent to the bottom of Davy Jones' Locker on Wednesday, when Villarreal were astonishingly thrashed 5-0 in the King's Cup by third divsion Polideportivo Ejido.

Los Angeles - It wasn't a thing of beauty, in fact it was plain ugly, but the Houston Rockets will take it.

Yao Ming had 21 points with 10 rebounds and the Rockets struggled to beat the visiting Memphis Grizzlies 82-71 on Wednesday night, in the season opener for both teams.

"You're going to have games where you play great and be on Sports Centre," said Ron Artest, who added 16 points in his Rockets' debut. "You're going to have games when you play bad and get the win. If it was ugly and we're 1-0, we'll take it."

Tracy McGrady netted 16 points while Argentina's Luis Scola finished with 12 and 13 rebounds for the Rockets, who won despite shooting an icy 36.8 per cent (28-of-76) from the floor.
