Small prey fish can grow a bigger 'eye' on their rear fins as a way of distracting predators and dramatically boosting their chances of survival, new research has found.Researchers from Australia's ARC Centre of Excellence for Coral Reef Studies have made a world-first discovery that, when...

The longest and largest study of the effectiveness of insulin pumps to treat type 1 diabetes in children has shown that the pumps are more effective at controlling blood sugar than insulin injections and cause fewer complications. The research is published in Diabetologia, the journal of the...

A gene that helps control the ageing process by acting as a cell's internal clock has been linked to cancer by a major new study.Scientists at The Institute of Cancer Research, London, found a genetic variant that influences the ageing process among four new variants they linked to myeloma -- one...

By carefully adjusting the function of crucial immune cells, scientists may have developed a completely new type of cancer immunotherapy -- harnessing the body's immune system to attack tumors. To accomplish this, they had to thread a needle in immune function, shrinking tumors without triggering...

A new way of analyzing data acquired in MR imaging appears to be able to identify whether or not tumors are responding to anti-angiogenesis therapy, information that can help physicians determine the most appropriate treatments and discontinue ones that are ineffective. Fuente :...
