In our search for learning about causal links between environmental or genetic factors and diseases we study associations as they occur in populations that provide access to data. We know that these associations have many reasons; most of these are not the causes we seek. Much attention (too […] The Nobel Prize is without doubt the most prestigious prize in science, not because of the amount of money the prize winner is given, but because of its history and the care the committee takes in selecting the best candidates given the principles laid down in its foundation.

In this stream of causation many epidemiologists are rafting quickly downstream towards molecular epidemiology or nano-epidemiology (at least the internet domain name has […]

HIV became much more than a threat and reminded us of the value of a rapid and international research response, openness in reporting and use of mass media to inform […] |
