Record-breakers in the news today...

The music of Adele has been voted as the most popular to fall asleep to.

In a survey of 2000 people undertaken by hotel chain Travelodge, the London-born soul singer was found to be the top artist to help people fall asleep at night.

Adele, who currently holds several World Records including the biggest-selling digital album in US and UK for her long-player 21, beat off stiff competition for the No.1 spot from Coldplay and Snow Patrol.

One musician whose work is unlikely to trouble Adele's at the top of the sleep-inducing charts is Jimi Hendrix, (pictured above), who is back in the news following the announcement that twelve previously unreleased tracks by the late guitar virtuoso are to be released on a new album next year.

The star's official website revealed the songs on People, Hell and Angels were recorded in 1968 and 1969 and are thought to have been intended for First Days Of The New Rising Sun, Hendrix's follow-up to Electric Ladyland, which he was working on around the time of his death.

A Fender Stratocaster that once belonged Hendrix currently holds the record for the most expensive guitar sold at auction, with the instrument being sold by his former drummer `Mitch' Mitchell for £198,000 at Sotheby's, London on 25 April 1990.

Plumes of smoke and ash have been billowing from New Zealand's Mount Tongariro.

The volcano, which has a starring role in The Lord of the Rings films as Mount Doom erupted for the second time in four months, sending debris two miles high.

The new eruption forced local residents to stay indoors and keep their windows shut and has also caused flights to be cancelled.

The biggest climatic disruption to air travel was caused by the erupting Eyjafjallajokull volcano, in Iceland, from 14 - 21 April 2010.

The eruption's ash cloud was carried by a jet stream towards mainland Europe causing 313 airports to close and 100,000 flights to be cancelled, leaving 7 million people stranded. The disruption is estimated to have cost the airline industry £1.4 billion ($2.2 billion).

Finally, a South Pacific island, shown on world maps as well as on Google Maps, doesn't actually exist, according to Australian scientists.

Positioned between Australia and French-governed New Caledonia, the apparently sizeable strip of land is named Sandy Island on Google maps and has featured in publications for over a decade.

However scientists from the University of Sydney now dispute its existence after visiting the area only to find the blue ocean of the Coral Sea.

The largest man-made floating island is the Mega-Float, which was opened to the public in 1999 at Yokosuka Port, Tokyo Bay, Tokyo, Japan.

The steel-built structure measures 1,000 m (3,280 ft 10 in) in length, 121 m (397 ft) wide and 3 m (9 ft 10 in) deep.
