Major climate models are based on a series of more specific overlapping models that are in constant interaction with one another. However, those describing the behaviour of sea ice have proved to be obsolete. As a result, researchers are now developing new ones, using concepts derived from mechanics.
Biological invasions are the second most common cause of species extinction on Earth, and also take a heavy toll on our health and the economy. On the occasion of the World Congress of the International Union for the Conservation of Nature (IUCN), to be held in Marseille (southeastern France) from 3 to 11 September, CNRS News takes a closer look at this crucial issue.
One of the central elements in the new sci-fi film Dune by Denis Villeneuve is a substance with extraordinary properties. Called â€śspiceâ€ť, it bears a resemblance to certain molecules already in use in our own world! The CNRS chemist Fabrice Chemla explains.

Historian Florent Brayard, co-director of the project, explains the impetus...
Mathematics The study of numbers has driven mathematics since antiquity. The constantly evolving field of arithmetic connects numbers and geometry, and is used in everyday applications, particularly in cryptography.
Ecology For the past 20 years, a scientific team has been monitoring the state of health of Barbeau Forest in the Seine-et-Marne region east of Paris. Researchers and engineers analyse the flux of carbon dioxide and water vapour between the forest and the atmosphere, with the goal of charting the impact...
Art history Using digital technology, a researcher has unravelled the secrets of the use of perspective by the Flemish painter Jan Van Eyck, a technique previously believed to be specific to the Italian Renaissance artists.
Biology Progress in microscopy continues to expand our window onto the world of the infinitesimally small. Whether in chemistry, biology, engineering or digital simulation, these images paint a phantasmagoric and yet factual portrait of the world that we live in, that we build, and that lives within us.
