1st Day part 2

Melatonin and Cancer
The real action - the scientific talks get underway with the lead by Dr Kristan Aronson, on  'Human health effects of exposure to light at night, with emphasis on biomarkers and breast cancer.'. This was a fascinating talk describing the observed relationship between the effects of shift work and the relationships to cancer.  After a session of statistics at university it was a real buzz to hear someone using terms such as 'the statistical power of a test' - makes it real and that the technical detail is a necessity.  The talk ranged over a number of issues and noted that melatonin is one of the most ancient hormones, present even in bacteria; melatonin is certain to prove to be a major driver of circadian rhythm and behaviour.
