Half a billion years ago, plants, until then exclusively aquatic, set out to colonise the land. This transition transformed the Earth and its atmosphere, paving the way for terrestrial vertebrates. Researchers have been hard at work piecing together the scenario of this revolution.

Prehistoric sites across France, such as the famous Chauvet Cave or L’Ile d’Yeu, are being closely monitored so as to understand how they are being endangered by climate change, and avoid the disappearance of rock paintings.

Arthur is a new submersible ROV (remotely-operated vehicle) designed for underwater archaeology. Offering unprecedented performance and versatility, it is able to explore shipwrecks for treasure and the marine life they harbour, at depths as great as 2500 metres.

The first World Glacier Day, and the International Year of Glaciers 2025, encourage us all to take action to preserve the vital role of glaciers in sustaining life on Earth for generations to come.

Over the past few months, our planet has been ìmpacted by intense solar flare activity on the Sun.
