London, Mar. 22 : United Kingdom’s new anti-terror strategy, which will be unveiled by Home Secretary Jacqui Smith next week, is claimed to be the most comprehensive counter-terrorism approach issued by any government in the world.

According to a Home Office spokesman, Smith wants the paper to go into more detail than ever before about how the authorities are seeking to prevent atrocities from happening and respond to attacks which take place.

The strategy will reflect security services'' judgment that the most serious terror threat to the UK continues to come from Osama bin Laden''s al Qaida network, the Daily Star reports.

London, Mar 22 : Austrian incest fiend Josef Fritzl is expected to chose a former nunnery converted into a comfortable modern prison as the place in which he will serve his life sentence.

The 74-year-old has been jailed for murder, rape, enslavement, coercion and incest after caging his daughter in a rat-infested dungeon for 24 years and fathering seven children by her, six of whom survived.

London, Mar 22 : British Defence Ministry abandoned plans for a secret computer database of UFO sightings for fear they would be mocked if its existence were revealed to the public, according to declassified government documents.

The idea was scrapped because officials did not want people to believe they were taking the idea of visitors from outer space seriously.

Instead, the MoD continued to keep only paper records of almost 1,200 sightings reported between 1987 and 1993, The Independent reports.

London, Mar 22 : Scientists are developing a robotic octopus that will be able to search the seabed with the same extraordinary dexterity as the real eight-legged cephalopod.

With no solid skeleton, the robot would be the world''s first entirely soft robot, say researchers.

The trouble with today''s remote-controlled subs, says researcher Cecilia Laschi of the Italian Institute of Technology in Genoa, is that their large hulls and clunky robot arms cannot reach into the nooks and crannies of coral reefs or the rock formations on ocean floors.

London, Mar 22 : Taking a special vitamin supplement during pregnancy can keep hydrocephalus, one of the most common birth brain defects, at bay, claim researchers.

According to scientists, who conducted tests on rats to reach the conclusion, results have shown a combination of folates dramatically reduces the rates of hydrocephalus - in which fluids build up in the brain''s chambers.

However, it's too early to say anything further, say researchers in the Journal of Neuropathology and Experimental Neurology.

London, Mar 22 : A leading professor is sucking all the fun out of the puzzle phenomenon - by revealing a formula to solve any Sudoku problem.

James Crook, an emeritus professor in South Carolina, will tomorrow publish his "pen-and-paper algorithm for solving Sudoku puzzles" on the website of the American Mathematical Society.

The algorithm boils down to five logical steps.

Sudoku fans, however, are aghast by the idea, reports The Times.

Colin Dexter, author of the Inspector Morse crime novels and a puzzle enthusiast, said: "I'm sorry to hear somebody's discovered how to do it. It's like using a computer program to work out crossword anagrams - it takes all the fun and struggle out of it."
