Two bowel cancer genes discovered

Two bowel cancer genes discovered

23 December 2012 Last updated at 23:38 ET UK researchers believe they have explained why some families are incredibly vulnerable to bowel cancer. They have found two genes, which are passed from parent to child, that greatly increase the risk of a tumour forming. Continue reading

Virus rebuilds heart’s own pacemaker

Virus rebuilds heart’s own pacemaker

16 December 2012 Last updated at 13:05 ET By James Gallagher Health and science reporter, BBC News A new pacemaker has been built inside a heart by converting beating muscle into cells which can organise the organ’s rhythm, US researchers report. The heartbeat is controlled by electrical signals and if these go awry the consequences can be fatal. Scientists injected a genetically-modified virus into guinea pigs to turn part of their heart into a new, working pacemaker. Continue reading

Blood test ‘finds brain tumours’

Blood test ‘finds brain tumours’

12 November 2012 Last updated at 03:41 ET By James Gallagher Health and science reporter, BBC News Tiny fatty balls ejected by cancer cells into the bloodstream have been used to detect deadly brain tumours, US researchers report. The spheres, known as microvesicles, share the unique characteristics of the cancer cells they come from, but are much easier to get hold off. A study, published in Nature Medicine 1 , showed a test could detect tumours in mice and human patients. Continue reading
