London, Nov 26 : Australian scientists are using mobile phones to listen in on koalas'' conversations in an attempt to translate what they are saying to each other.

The boffins have placed mobiles in the trees of a koala territory to record their distinctive bellows.

Researchers have also tracked koalas on St Bees Island off northeast Australia by satellite to monitor their movements and mobile phones have been placed amongst the trees to listen in.

The mobiles have been charged by solar power and car batteries – and they are able to record the koalas'' bellows.

Then, the phones download the recordings to a computer at the University of Queensland in Brisbane, reports the Scotsman.

London, Nov 26 : Reports indicate that the temperature inside India’s first unmanned lunar spacecraft Chandrayaan-1 has gone over 50 degrees Celsius, prompting scientists to explore various options to cool down the unexpected surge.

According to a report by BBC News, scientists say that the problem arose because of very hot temperatures during the lunar orbit.

“Now the moon, our satellite and the sun are in same line this means our craft is receiving 1,200 watts of heat from the moon and 1,300 watts from the sun per meter square,” said M Annadurai, project director of Indian’s moon mission.

If the temperature is not kept in check, many instruments on board the orbiter may fail to perform, according to scientists.
