London, October 9 : Ultrafast, power-saving electronic devices may have come a step closer to reality with American researchers producing superconducting thin films.

Scientists at the U. S. Department of Energy''s (DOE) Brookhaven National Laboratory say that they have successfully created two-layer thin films where neither layer is superconducting on its own, but which exhibit a nanometre-thick region of superconductivity at their interface.

London, Oct 9 : A new phase change material with the potential to change the design of future memory storage devices has been invented by scientists at Singapore ASTAR''s Data Storage Institute (DSI).

Phase change materials can modify their structure between amorphous and crystalline at high speed.

The materials, these days, are used to make Phase change memory (PCM), considered to be the most promising alternative to replace FLASH memory.

Usually, PCM is worked by changing phase change materials'' structure through applying an electric current. But now, phase change can be initiated by means of switching the new phase change materials by using magnetic fields, reports Nature.

Berlin - Global warming calculations have been too optimistic, and the sea level round the globe is likely to rise a full metre this century, two senior German scientists warned Wednesday.

Hans Joachim Schellnhuber, who heads the Potsdam Institute for Research on Global Warming Effects and Jochem Marotzke, a leading meteorologist, said UN-backed data on climate change, predicting a rise of 18 to 59 centimetres, was out of date.

"We now have to expect that the sea level will rise by a metre this century," said Schellnhuber in Berlin.

London, Oct 9: The longer you stay inside a shop, the more likely you’re to spend, reveals a new mobile tracking system, called FootPath.

The software, developed by UK company, Path Intelligence, can track movements of mobile users over specified periods of time.

FootPath works by reading an anonymous identification number, called temporary mobile subscriber identity, or TMSI, that mobile phones transmit and can then track their movements.

At times, some people, when are brutally drunk tend to send e-mails to their friends, office mates, and lovers without even being conscious about what they are writing, which they later regret. 

To solve this problem, Gmail engineer Jon Perlow has come out with a solution and has introduced Mail Goggles, a feature which once activated will question the sender a series of problematic questions before the mail is sent. 

In a unique move, lectures by well known academics would be made available through Apple’s iTunes by the universities of Oxford and Cambridge. 

Nearly 150 hours of free video and audio podcasts of lectures and ideas from the leading thinkers of the world, will be published by Oxford. 

One can now access the education downloads, which include a film about the University of Oxford's fundraising campaign "Oxford Thinking" that features ex-Python and seasoned traveller Michael Palin.
