Throughout most of the 20th Century, the question of cancer causation divided oncologists between the infectious and the mutation fields. Both sides counted innumerable pieces of evidence in their favor, but the mutation theory of the origins of cancer eventually won the contest and constitutes now the paradigm in oncology.

Indeed life expectancy is one of the criteria on which we judge whether a nation is doing well or badly.

There's a new column starting this month. “In the Lab” let us discover labs and facilities spread around our country.

How do eukaryotic cells regulate the size and activity of different compartments to couple functional competence and homeostasis? How do they readapt to fulfil novels physiological tasks? Over the last years, some answers to these fundamental questions came from studies on the secretory system.

The recent popularity of systems approaches in molecular biology is perhaps best understood as a reaction to technological developments beginning in the 1990s, notably the large sequencing projects such as the Human Genome Project.
