Sydney - The global financial crisis has done wonders for the dismal science of economics.

From Anchorage to Ankara the spooky talk about global warming has given way to debate on toxic debt and stimulus packages, job security and interest rates.

There's a fresh cast of characters in the news bulletins: out went the sports stars and fashion labels and in came Freddie Mac and Fannie Mae, Warren Buffett and Ben Bernanke.

Listen in on the conversations of commuters and be amazed at the discourse.

Sydney  - Australian Prime Minister Kevin Rudd had hoped that when the Group of 20 (G20) met in London in April, he would be among the few representing an economy still growing.

Sydney - Australian police promised more arrests Wednesday as a squad dedicated to breaking up motorcycle gangs rolled through major cities picking up suspects in a show of force.

The crackdown follows Sunday's outrage when a Hells Angels member was bludgeoned to death in front of horrified passengers at Sydney airport.

Fears of outright war between rival gangs were stoked by a double murder in Canberra on Tuesday. But police warned against immediately linking the killings to gang rivalry.

Sydney  - Six of the 10 survivors from a pod of 80 whales that beached themselves near Margaret River on Australia's west coast earlier this week came ashore again Wednesday.

The long-finned pilot whales were spotted just 6 kilometres up the coast from Flinders Bay, where they were shepherded out to sea by a volunteer army of nature lovers less than 24 hours earlier.

The survivors had been loaded onto trucks at Hamelin Bay, where they initially came ashore Monday, and taken the 20 kilometres to Flinders Bay for release in deeper waters.

Sydney, March 24 : Scientists have identified two new greenhouse gases – one emitted by the electronic industry and the other used in pest control, which are rapidly accumulating in the atmosphere.

(NF3) and sulfuryl fluoride (SO2F2), the two new gases.

Sydney  - Sydney police on Monday bolstered a squad dedicated to breaking up motorcycle gangs after a Hells Angels member was bludgeoned to death in front of horrified passengers at Sydney airport when rival gangs clashed at a check-in counter.

"This is a new low in the activities of these criminal gangs," New South Wales state Premier Nathan Rees said of Sunday's killing. "Where once they kept these things between themselves, this has now overlapped into the public domain."
