Worth an article: my April 2009 tweets


Last month the French magazine Science et Vie [Fr] dedicated a series of articles to the earthquake risks induced by dams, mines, oil drilling and geothermal power.

These are the conclusions of a recent study carried out by two specialists from the London School of Hygiene & Tropical Medicine and published in the International Journal of Epidemiology. This was the topic of an interesting article my dad sent me on how obesity is bad for climate change. […]
