Back When European Ecosystems Absorbed Less CO2

A study by an international team of researchers involving LSCE shows that CO2 absorption by terrestrial ecosystems in Europe observed during the past decade is due to the persistence of a particular configuration of regional atmospheric circulation.

The Magnetic Games Between an Exoplanet and its Host Star

Most exoplanets known to date orbit very close to their star, which favors a magnetic "connection" to their host. An international collaboration involving IRFU has used supercomputer simulations to demonstrate that energies brought into play create effects which should soon be observable using the Canada France Hawaii telescope and ESA's PLATO satellite (Planetary Transits and Oscillations of Stars).

A Volcanic Eruption Depicted in the Chauvet Cave

About 36,000 years ago, human residents of the Chauvet-Pont d’Arc cave (Ardèche, France) witnessed volcanic eruptions from the surrounding hills in the Bas-Vivarais region. Such is the conclusion of a study by a collaboration led by LSCE, based on recent 40Ar/39Ar datings of eruptions, and suggesting that the spray-shape signs in the Megaloceros Gallery would be the oldest representation of these natural disasters.
