While looking for ways to treat pain in those with musculoskeletal disorders, researchers examined studies in which sleep supplement melatonin had been used. 

A study into the behaviour of immune cells in coeliac disease patients showed surprising results. Instead of being overactive, T cells in coeliac disease were subdued, and didn't survive as long as T cells from healthy people. 

Spinal stimulators have been in use for many years, but the evidence for their benefit, or otherwise has been unclear until now.

The first cases of H5N1 bird flu have been confirmed following the discovery and rescue of a sick bird on a remote beach in Western Australia.

Since then more sick birds have been reported, with authorities stressing the safest approach is to take a photo and notify them.

While the risk of bird to human transmission is low, there have been almost one thousand cases of H5N1 bird flu in humans since 2003.

So what happens now?
