Serious gaming can be used to enhance surgical skills, but games developed or used to train medical professionals need to be validated before they are integrated into teaching methods, according to a paper in the October issue of the surgical journal BJS.
Researchers have newly identified three genetic regions associated with primary biliary cirrhosis (PBC), the most common autoimmune liver disease, increasing the number of known regions associated with the disorder to 25. The team used a DNA microchip, called Immunochip, to survey more thoroughly regions of the genome known to underlie other autoimmune diseases to discover if they play a role also in PBC susceptibility.
The hundreds of researchers working on the ENCODE project have revealed that much of what has been called 'junk DNA' in the human genome is actually a massive control panel with millions of switches regulating the activity of our genes. Without these switches, genes would not work - and mutations in these regions might lead to human disease.
Experts agree that, more than ever before, modern wars will be fought in the cyber zone, targeting an enemy's communications technology to cause untold damage. Now a Tel Aviv University researcher is suggesting that the same tactics should be employed in the battle against one of the body's deadliest enemies - cancer.
Researchers at King's College London, in collaboration with European research institutes ICFO (Barcelona) and AMOLF (Amsterdam), have broken the limit of light resolution at the nanoscale and delivered a fundamental insight into how light and matter interact, which could lead to the development of enhanced bio-sensors for healthcare and more efficient solar cells and displays.
About 25,000 Danes currently live with congenital heart defects. Both heredity and environment play a role for these malformations, but exactly how various risk factors influence the development of the heart during pregnancy has been a mystery until now.
With the aid of tiny silicon tubes and one of Europe's most sophisticated centres for microscopy, scientists have been able for the first time to observe directly bacteria in chronic infections. Researchers can now see precisely how bacteria and the immune system interact in living tissue.
