Le CNRS part en échappées

Elephants, crocodiles, hippopotami… In Botswana, the Okavango delta is a real paradise for the local fauna during the flood, which lasts several months a year. In this documentary, a team of French scientists takes you on board to study the geological, hydrological and climatic features of this unique region.

In recent years parasites such as the tiger mosquito or the tick have continued to conquer new territory, especially in Europe and the United States. What causes this proliferation? How to protect from it? The scientific community is trying to shed light on the phenomenon, which is responsible in particular for the transmission of certain animal diseases to humans.

The decline of coral reefs around the world seems irreversible. However, scientists have not yet spoken their last word! In this report from French Polynesia, a team of researchers attempt to reverse this trend by helping coral adapt to climate change.

Polar auroras are fascinating events that are regularly visible on Earth. Yet do they occur on other planets, such as Mars for example? And if so, how can they be observed? In this report, scientists tracking these auroras have discovered another phenomenon that had never been described on the Red Planet so far.

Two years after the fire of 15 April 2019, Notre-Dame will be the venue of a huge scientific investigation to uncover the cathedral's secrets and to help restore it. In this film, discover how researchers are drawing information from stone and iron to understand how the original builders constructed a cathedral that was much taller than its contemporaries. The ""iron"" team is focused on the remains of the upper part of the cathedral and the nails of the roof frame, using…

À première vue, peu de choses affleurent à la surface de ce bloc de construction de deux mètres de long pesant une demie tonne. Le bloc de l'Alcazar, découvert à Marseille et conservé au Musée d'Histoire de la ville, est pourtant une curiosité sans équivalent. Eclairé sous une nouvelle lumière, c'est une partie de l'histoire de la Méditerranée d'il y a 2600 ans qu'il raconte alors… Il fait apparaitre des centaines de graffiti antiques superposés, de lettres, de silhouettes humaines et…

Dans le cadre du projet de science participative « Derrière le blob, la recherche », porté par le CNRS, 15.000 volontaires s'apprêtent à accueillir cet étrange organisme unicellulaire, avec lequel ils devront mener des expériences en suivant des protocoles scientifiques très stricts. Les nombreux résultats récoltés permettront à la biologiste Audrey Dussutour d'étudier l'impact du changement climatique sur le blob.

NASA's new James Webb Telescope (JWST) is expected to revolutionise space observation. It was launched on 24 December 2021 from Kourou, French Guiana. After a 30 day journey, it reached the Lagrange point L2 at 1.5 million kilometres from the Earth in the opposite direction to the Sun. The long-awaited successor to Hubble, Webb is three times larger and has a mirror spanning more than six metres, becoming the world's largest orbital observatory. It took international teams more than 25 years to…
