Smile and art smiles with you

Paintings developed by scientists at the University of Bath and the University of Boston recognise human facial expressions and morph accordingly, says Physorg.com.

Scowling prompts a darker image with violent brush strokes, while smiling brings out vibrant colours that are gently portrayed.

With the use of a Webcam mounted atop the painting, an image of the viewer`s face is captured and sent to a computer program for analysis.

According to BBC News, scientists have adopted a technique to coax out finer and previously unseen details of Archimedes`s writings.

The X-rays are formed in a particle accelerator to generate powerful "synchrotron" light which enables scientists to look inside matter at the molecular and atomic scale.

This technique works so well due to the iron atom used in the ink to emit a particular glow. Each page takes 12 hours to reconstruct and text is viewed on a computer screen.

A recent Symantec survey shows 89% of respondents owned digital cameras, yet only one-third are backing up their shots, says BBC News.

Approximately 50% take more than 10 photos a month and 30% said they do not print out any hard copies at all.

Lee Sharrocks, consumer sales director of Symantec UK, warns all photographers: "Unfortunately it only takes one computer virus or accident to critically damage a PC, with the possible result of losing stored data forever."

The Church of England`s publishing arm has advised clergy to ignore Symantec security warnings, after its Norton Antivirus product wrongly identified church software as spyware, and various files were deleted as a result, reports CNet News.

The incorrectly identified software is a tool called Visual Liturgy, used to plan, create and deliver church services.

The tool was mistakenly identified as the spyware, Sniperspy. According to the report, about 4 500 churches with about half a million churchgoers have been badly affected.

Norwegian journalist Bjoern Benkow`s interview with Bill Gates has been identified as a complete fake, USA Today says.

The interview was printed in the Norwegian magazine Mann and top-selling Swedish tabloid daily Aftonbladet, and was based on an interview Benkow had with Gates during a two-hour commercial flight in Europe.

Entitled "Big Bill" the interview supposedly touches upon issues like competition with search engine Google and Europe`s anti-trust actions against Microsoft.
