Orphaned chimpanzees do not suffer from chronic stress
Orphaned chimpanzees do not suffer from chronic stress
The loss of a loved one can be a defining moment, even in the animal world. In chimpanzees, for example, individuals whose mothers die when they are young are smaller than their counterparts, reproduce less and are also more likely to die at a young age. But why? To find out, an international research team 1 led by a CNRS researcher 2 studied the shortand long-term effects of maternal loss on the stress levels of orphaned chimpanzees over a 19-year period.

French ESA astronaut Thomas Pesquet to continue experiments on foams
French ESA astronaut Thomas Pesquet to continue experiments on foams
Studying how liquid foams evolve over time is difficult, if not impossible, on Earth because of gravity. The FOAM-C experiment, which began in 2020, was designed to study liquid foams in zero gravity on board the ISS. New samples will be set up by French astronaut Thomas Pesquet on Friday, June 11. The FOAM-C experiment studies the properties of liquid foams in zero gravity.

ALPALGA: the search for mountain snow microalgae
ALPALGA: the search for mountain snow microalgae
High elevation snow is home to previously unknown species of microalgae. Scientists have created the ALPALGA consortium to study this ecosystem, which is threatened by climate change. According to their initial results, these microalgae are tiered to elevation, just like herbaceous plants and trees.

Antarctica: how have temperatures varied since the last glacial period?
Antarctica: how have temperatures varied since the last glacial period?
Scientists have established the most reliable estimates to date of past temperature variations in Antarctic They highlight significant differences in behaviour between West and East Antarctica. This study makes it possible to test and consolidate future climate projections. Antarctica has experienced significant temperature changes, especially since the last glacial period.

Jebel Sahaba: A succession of violence rather than a prehistoric war
Jebel Sahaba: A succession of violence rather than a prehistoric war
Since the 1960s, the Jebel Sahaba cemetery (Nile Valley, present-day Sudan) has become the emblem of organised warfare during prehistory. Re-analysis of the data, however, argues for a succession of smaller conflicts. Competition for resources is probably one of the causes of the conflicts witnessed in this cemetery.

Optogenetic Methods Restore Partial Vision in a Blind Patient
Optogenetic Methods Restore Partial Vision in a Blind Patient
Results of this research, a world-first, were published in  Nature Medicine on May 24th, 2021. An international research team has shown that optogenetic therapy has helped a patient with retinitis pigmentosa to partially regain visual function. This is a milestone step towards a type of gene therapy that could restore vision.

A plant-fungi partnership at the origin of terrestrial vegetation
A plant-fungi partnership at the origin of terrestrial vegetation
Plants that exist on land today have genes that allow them to exchange lipids with beneficial fungi This plant-fungus partnership is at the origin of the transition of plants from aquatic life to terrestrial life 450 million years ago, the first plants left aquatic life. Researchers from the CNRS and the Université de Toulouse III - Paul Sabatier, in collaboration with INRAE, have succeeded in demonstrating that this colonisation of land by plants was made possible by a partnership between plants and fungi.

Colonisation of the Antilles by South American fauna: giant sunken islands as a passageway?
Communication from CNRS on May 18, 2021. Publication of LGL-TPE in the June 2021 issue of Earth-Science Reviews. Fossils of land animals from South America have been found in the Antilles. The appearance/disappearance of archipelagos is due to tectonic plate movements and glacial-interglacial cycles.

Present-day geodynamics of the Western Alps: new insights from earthquake mechanisms
Publication of LGL-TPE in the journal Solid Earth on July 21, 2021. Due to the low to moderate seismicity of the European Western Alps, few focal mechanisms are available in this region to this day, and the corresponding current seismic stress and strain fields remain partly elusive. The development of dense seismic networks in past decades now provides a substantial number of seismic records in the 0-5 magnitude range.

In the Alps, climate change affects biodiversity
In the Alps, climate change affects biodiversity
The European Alps is certainly one of the most scrutinized mountain range in the world, as it forms a true open-air laboratory showing how climate change affects biodiversity. Although many studies have independently demonstrated the impact of climate change in the Alps on either the seasonal activity (i.e.

Africa's oldest human burial site uncovered
Africa’s oldest human burial site uncovered
The discovery of the earliest human burial site yet found in Africa, by an international team including several CNRS researchers 1 , has just been announced in the journal Nature . At Panga ya Saidi, in Kenya, north of Mombasa, the body of a three-year-old, dubbed Mtoto (Swahili for 'child') by the researchers, was deposited and buried in an excavated pit approximately 78,000 years ago.

Structural and molecular basis of cross-seeding barriers in amyloids
Publication of CRMN in the journal PNAS on January 5, 2021. Neurodegenerative disorders are frequently associated with -sheet-rich amyloid deposits. Amyloid-forming proteins can aggregate under different structural conformations known as strains, which can exhibit a prion-like behavior and distinct pathophenotypes.

When Chauvet Cave artists created its artwork, the Pont d'Arc was already there
When Chauvet Cave artists created its artwork, the Pont d’Arc was already there
The Chauvet Cave, which lies by the entrance to the Gorges of the Ardèche, is home to the world's oldest cave paintings, dating back 36,000 years. Their state of preservation and aesthetic qualities earned them a spot on the World Heritage List in 2014, 20 years after their discovery. The location of the cavern-surrounded by a remarkable landscape, next to the Pont d'Arc natural archway-raises the question of whether the people who executed these artworks looked and walked out upon the same landscape as today.
