London, Dec 4 : Scientists have made the world’s first superconducting transistor, a long-standing goal for applied physicists, which could lead to dramatically faster microchips, promising a revolution in PCs (personal computers).

According to a report in New Scientist, Andrea Caviglia and his colleagues at the University of Geneva in Switzerland developed the transistor.

Last year, Caviglia and his colleagues grew a single crystal containing two metal oxides, strontium titanate and lanthanum aluminate, as separate segments.

At the interface of these materials, the team found a layer of free electrons called an electron gas.

LINCOLN, England, Dec. 4  -- A street cleaner in Lincoln, England, says police have allowed him to keep a bag containing an estimated $20,000 in shredded cash he found in a trash bin.

Graham Hill said he took the carrier bag containing the cut-up money to police after discovering it while emptying trash bins. The shredded currency was returned to him after it remained unclaimed for six months, the Daily Mail reported Wednesday.

"This was a very unusual case and despite our inquiries the circumstances of why and how the money came to be torn up and put in the bin remains a mystery," Detective Constable Nick Cobb said. "Following extensive inquiries, there was no evidence that the money was stolen or linked to any criminal activity."

London, Dec 4 : Manchester United players have a hi-tech telly installed in their dressing room that reminds them about their vital appointments — such as pedicures and hair cuts.

The telly also tells the players who is available to run their bath and how their grub is cooked.

“I don’t go into the first team dressing room very often, but I popped in recently to look for a member of staff,” the Sun quoted Manchester United coach Brian McClair, as saying.

“I noticed there was a new addition to the room — a large flat-screen TV. I switched it on and saw there was a scrolling screen informing players of details for the day.

London, Dec 4 : Mobile mogul Nokia has announced the launch of a system that would link your cellphone to automatic home systems and help control heating, home security cameras and even draw curtains.

The Nokia Home Control Centre is a wireless router, which can interface with equipment around the home.

The company has collaborated with European energy company RWE to manage heating systems and is hoping other firms will sign up soon.

The gadget is being demonstrated at Nokia World in Barcelona.

"We believe that the mobile device is the ideal interface to control home intelligence, especially when the user is not at home," BBC quoted Teppo Paavola, vice president of business development at Nokia as saying.

London, Dec 4 : Increasing noise pollution in the world’s oceans is threatening the survival of sea life like whales and dolphins, according to a discussion in a UN-backed conference.

According to a report by BBC News, in the Convention on the Conservation of Migratory Species of Wild Animals, it was determined that the noises sea creatures use to communicate are being drowned out by noises from commercial shipping, new military sonar and climate change.

The marine life becomes disoriented, cannot find mates or food and behave differently, according to the scientists.
