[00:01:00] The rattle of the rattlesnake’s tail has long been something of a mystery for evolutionary biologists, because there’s no ‘half-shake’. Well a study by David Pfennig at the University of North Carolina at Chapel Hill may suggest they started off shaking their silent tails, but over time developed a rattle as a signal to predators.
[00:06:54] The long awaited results of a 10 year prostate cancer trial were published last week in the New England Journal of Medicine. The study looked at 1,643 men diagnosed with early prostate cancer, and found that those who actively monitored their cancer instead of immediately starting treatment had the same minuscule risk of death as men who had either radiation therapy or surgery straight away.
Jo Benhamu is a clinical trials coordinator in radiation oncology.
