Mars: new evidence of an environment conducive to the emergence of life
Scientists have discovered fossil evidence of a cyclical climate on Mars, with wet and dry seasons like those on Earth. This environment, in which simple organic molecules have already been discovered, may have provided ideal conditions for the formation of complex organic compounds. This work opens up new prospects for research into the processes underlying the origin of life, of which no vestiges remain on Earth.

Air Pollution Accelerates Eye Ageing
Numerous studies are now reporting the harmful effects of air pollution on the central nervous system (neurodegenerative diseases in adults, neurodevelopmental disorders in children). Glaucoma, the second leading cause of blindness worldwide, is a neurodegenerative disease of the optic nerve whose principal characteristic is thinning of the retinal nerve fiber layer.

The first prehistoric wind instruments discovered in the Levant
Although the prehistoric site of Eynan-Mallaha in northern Israel has been thoroughly examined since 1955, it still holds some surprises for scientists. Seven prehistoric wind instruments known as flutes, recently identified by a Franco-Israeli team 1 , are the subject of an article published on 9 June in Nature Scientific Reports .

Agricultural intensification is driving a decline in bird populations across Europe
Bird populations across continental Europe have declined by 25% in 40 years, with this figure reaching nearly 60% for species found in agricultural environments. Intensive farming is the main source of pressure linked to declining bird populations. These findings come from the largest and most comprehensive bird study to date in Europe.

New viruses related to both giant viruses and herpesviruses
A team from the CEA and CNRS have discovered the existence of mirusviruses: a major group of viruses abundant on the surface of the seas and oceans, where they infect single-celled plankton. These findings appear in Nature on 19 April. The discovery provides a better understanding of the scope of ocean biodiversity and the importance of viruses in these ecosystems.

Climate change: improved prediction of heatwaves thanks to AI
Extreme heatwaves are rare, but they have major consequences on living beings and their environments. Anticipating their arrival is a central challenge. In an article published in Physical Review Fluids on April 4th, an interdisciplinary team of French scientists 1 from the CNRS, the CEA, and the Claude Bernard University Lyon 1 unveiled artificial intelligence 2 that can predict heatwaves.

Laure Bonnaud-Ponticelli: ’The octopus has phenomenal analytical capacities!’
Gone are the days when the octopus was, in the collective imagination, a frightening sea monster attacking Jules Verne's Nautilus. The image of the octopus has now changed. For example, the cephalopod took on the pseudonym Paul during the 2010 soccer World Cup, and made predictions about the outcomes of games (more or less successfully.

Acorn production cycles influence wild boar populations
According to a study published in The American Naturalist on 6 January 2022, sequences of environmental events over time influence population dynamics in wild species. A research team led by Marlène Gamelon, a researcher at the CNRS 1 , has studied the influence of sequences of oak mast seeding events over the years on a population of wild boars 2 , which are major consumers of acorns.

Glaciers disappear more than expected
How will our glaciers evolve during the 21st century - In a new study to be published on January 5 in the journal Science , an international team 1 , including scientists from CNRS and the University Paul Sabatier Toulouse III, reveals a loss of glacier mass greater than previously projected. According to their work, this loss increases by 14% to 23% compared to previous projections, including those used in the last IPCC report.

Developing silicones that are friendlier toward health and the environment
Polysiloxanes, the scientific name for silicones, possess exceptional properties, and are used in numerous fields ranging from cosmetics to aerospace. They are absolutely everywhere! However, small cyclic oligosiloxanes impurities - including substances classified as toxic for the environment and identified as potential endocrine disruptors - can form during their synthesis.

Hypertension: A Mixture of Air Pollutants Could Cause Repeated High Blood Pressure Peaks
Air pollution is an acknowledged environmental factor in high blood pressure. It consists of a mixture of particles and gases whose combined effects on human health are not yet well known. A team from Inserm and Sorbonne Université, assisted by international collaborators, used continuous monitoring to study the daily life impact of a mixture of five air pollutants on the blood pressure of 221 MobiliSense study participants in the Greater Paris area.

Extreme Temperatures During Pregnancy: A Possible Impact on the Lung Development of Newborn Girls
Exposure to extreme temperatures from the fetal stage could impact health. This is what suggests a study by researchers from Inserm, Université Grenoble Alpes and CNRS, based on the SEPAGES cohort , intended to study the impact of various environmental factors on the health of pregnant women and their children.

Discovery of an alternative organic synthesis route in hydrothermal environments
Publication of the LGL-TPE in the journal Nature Communications on January 21, 2023. Communication of the CNRS-INSU on February 3, 2023. The abiotic reactions that allow the formation of complex, potentially prebiotic organic molecules are a missing key to determining where life may have emerged. The limited variety and simplicity of the abiotic organic molecules observed have long discredited the theory of a hydrothermal origin for the emergence of life on Earth.

A CO2 sink in the South Pacific ocean desert
A newly identified process of natural iron fertilization in the ocean fuels regional CO2 sinks. This was demonstrated by a study published May 25 in Science and co-authored by 25 researchers from the Tonga project. This project was led by two researchers from the IRD and CNRS, with over 90 scientists from 14 French laboratories based in mainland France, New Caledonia, and 6 international universities.

Loss of glaciers faster than expected
How will our glaciers change during the 21st century? In a new study whose findings are published in Science (5 January), an international team 1 , including scientists from the CNRS and Université Toulouse III-Paul Sabatier, has demonstrated a loss of glacial mass greater than earlier projected-and specifically, 11% to 44% higher than estimates used in the most recent IPCC report.

Microfibers of the Mediterranean
A consortium of bacteria form on the microfibers of the Mediterranean Sea, becoming "floating homes for bacteria". Maria Luiza Pedrotti, a CNRS researcher at the Villefranche-sur-Mer oceanography laboratory has reported the presence of a pathogenic bacterium on the tiny textile fibers found in the deep blue sea.
