When variations in Earth's orbit drive biological evolution

Coccolithophores are microscopic algae that form tiny limestone plates, called coccoliths, around their single cells. The shape and size of coccoliths varies according to the species. After their death, coccolithophores sink ...

Tempera painting probed on the molecular scale

In contrast to the oil painting technique that supplanted it at the end of the 15th century, tempera painting, practiced on wood panels, walls or canvas has received little attention on the physico-chemical scale. This painting ...

First European map of the insulating effect of forests

To cool off in summer, there's nothing better than a walk in the woods. Trees act as a buffer that cools the air beneath their foliage in summer and warms it in winter. This phenomenon is caused not only by the protection ...

Continental growth is not a continuous process

The continents, a specific feature of our planet, still hold many secrets. Using chemical data on sedimentary rocks compiled from the scientific literature from the 1980s to the present day, CNRS researcher Marion Garçon ...

Part of the universe's missing matter found

Galaxies can receive and exchange matter with their external environment thanks to the galactic winds created by stellar explosions. Via the MUSE instrument from the Very Large Telescope at the ESO, an international research ...

New viable means of storing information for quantum technologies?

Quantum information could be behind the next technological revolution. By analogy with the bit in classical computing, the qubit is the basic element of quantum computing. However, demonstrating the existence of this information ...

Bird and mammal diversity is declining with biological invasions

The introduction of invasive species leads to a decline in certain native species. A team of researchers from the CNRS and the University of Paris-Saclay has managed to show that 11% of the global phylogenetic diversity of ...

InSight mission: Mars unveiled

Using information obtained from around a dozen earthquakes detected on Mars by the Very Broad Band SEIS seismometer, developed in France, the international team of NASA's InSight mission has unveiled the internal structure ...
