Washington, Nov 12: Cambridge scientists have made a major breakthrough in rheumatoid arthritis. They have genetically engineered a drug-inducible form of Foxp3 gene, which when activated can prevent the autoimmune reaction characterised by the disease.

Rheumatoid arthritis is a painful, inflammatory type of arthritis that occurs when the body''s immune system attacks itself.

And the new strategy developed by scientists at the Medical Research Council''s Laboratory of Molecular Biology in Cambridge, may open the door for therapy development for rheumatoid arthritis.

Generally, immune cells develop to recognise foreign material – antigens; including bacteria - so that they can activate a response against them.

London, Nov 12: One of former British Prime Minister Tony Blair’s bodyguards triggered a security scare at Israel’s Ben Gurion Airport when he accidentally fired a shot.

Blair was in Israel for peace talks and was rushed on to his plane amid the panic. The weapon went off as it was being unloaded ahead of the flight.

“There was an incident this morning at Ben Gurion Airport when one of Blair’s bodyguards’ guns accidentally went off,” police spokesman Micky Rosenfeld said.

London, Nov 12: A Royal Commission report in UK has raised concern that just like asbestos, nanomaterials may turn out to be fatally dangerous for humans in the future.

The report called for extensive safety checks to be implemented, or else, the use of nanomaterials may actually kill people in the future.

The experts, analysing the effects of the technology, fear that when nanomaterials escape into the environment they can damage people and wildlife.

However, it may be too late before the effects become visible.

Already, general usage materials such as asbestos, leaded petrol, CFCs and cigarettes, were introduced without giving an eye to the potential damage.
