London, Mar 9: People who take day-time naps daily may be at an increased risk of developing type 2 diabetes, according to a new study.

Researchers from University of Birmingham have revealed that during their study, people who slept during the day were 26 per cent more likely to become diabetics.

While the condition is often attributed to unhealthy lifestyles and being overweight, lack of good night sleep is also known to be a contributing factor

And regular nappers are less likely to sleep well at night.

London, Mar 9: A new study, conducted by British researchers, has cast doubt on claims that fish oil can ward off dementia in old age.

Initially, data from a trial of more than 800 older people showed that those who eat plenty of oily fish seem to have better cognitive function.

However, factors such as education and mood explained most of the link and researchers need to explain what, if any, benefits fish oil has on the ageing brain.

London, March 9 : Researchers in London have discovered a way to stop cancer cells from spreading, which may prevent about 90 per cent patients.

Scientists at the Institute of Cancer Research, a constituent college of the University of London, say that rather than concentrating on stopping the formation on tumours, they focussed on singling out the enzyme that allows cancer to spread throughout the body.

The researchers say that their groundbreaking study led to the discovery that an enzyme called LOX is crucial in promoting the spread of the disease throughout a patient's body.

Lead researcher Dr. Janine Erler said called her team's discovery "the crucial missing piece in the jigsaw we have been searching for".

Although Europe is on the verge of eliminating measles, there have been outbreaks threatening the progress.

The Copenhagen-based regional WHO office attributed the lower immunization rates "to a combination of vaccine scepticism" as well as "the success of immunization programmes in earlier generations."
