TB test 'could save many lives'
BBC NEWS
A new diagnostic test for active tuberculosis infection could potentially save million of lives.
The test, developed by Imperial College London, has won a £10,000 award for medical innovation.
By growing samples in a special liquid, and analysing them with a sophisticated microscope, the TB bacteria can be identified in days, rather than weeks.
TB is the world's leading curable infectious killer, claiming 5,000 lives a day.
If left untreated, almost 70% of people with TB will die.
A single person with infectious TB can infect between 10-15 people a year.
The number of cases in the UK has increased by 25% over the last 10 years.

Remains of 'Godzilla' croc found
BBC NEWS
The fossilised remains of a crocodile that ruled the oceans 140 million years ago have been discovered in Patagonia.
Scientists have nicknamed the creature Godzilla, because of its dinosaur-like snout and jagged teeth.
The US-Argentine team of researchers believes the animal was a ferocious predator, feeding on other marine reptiles and large sea creatures.
The species is formally known as Dakosaurus andiniensis and has been unveiled in the journal Science.

Hormones make women safer drivers
BBC NEWS
The female hormone oestrogen could give women the edge when it comes to tasks such as safe driving, say researchers.
Tests showed attention span and ability to learn rules were far better among women than men.
The Bradford University scientists told a hormone conference in London how tasks requiring mental flexibility favour women over men.
A woman's oestrogen levels may prime the part of the brain involved in such skills - the frontal lobe - they said.
They asked 43 men and women aged 18-35 to perform a battery of neuropsychological tests that assessed skills such as spatial recognition memory, rule learning, attention, planning and motor control.
The women were far better at being able to shift their attention from one stimulus to another, making it easier for them to perform everyday actions like driving and reading.
