Sorbonne University Alliance On March 4, a historic agreement was reached by the United Nations to preserve marine biodiversity. Christophe Prazuck , director of the Océan Institute , discusses this major step forward and the participation of the Sorbonne University Alliance in this international scientific effort.

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.

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.

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.

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.

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.

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.

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.

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.

In bocage landscapes, the hedgerows that border cultivated fields provide many services. However, they are often perceived as sources of weeds, those wild plants generally called "weeds" and considered undesirable. Scientists from INRAE, in partnership with teams from the University of Rennes 1, CNRS and ANSES, studied the impacts of bocage landscapes on weeds.

For the first time, a digital model has shown that both fishing and climate-induced environmental change are responsible for the collapse of cod stocks in the North Sea. Taking into consideration these two factors together is crucial for the sustainable management of fish stocks. Using a new digital model, an international team led by researchers from the oceanology and geosciences laboratory (LOG) (CNRS/Université de Lille/Université du Littoral Côte d'Opale) has shown how fishing and climate affect cod stocks in the North Sea.

Marine protected areas (MPAs) are one of the solutions being put forward to help adapt to and mitigate the effects of climate change. To demonstrate their effectiveness, scientists from CRIOBE (CNRS/École Pratique des Hautes Etudes/UPVD), as part of an international team 1 , analysed 22,403 research articles on MPAs.

Trees play an essential role in the well-being of city dwellers - but for how long? An international research team, including a CNRS researcher from the Ecology and Dynamic of Anthropogenic Systems laboratory at the University of Picardy Jules Verne (Laboratoire Ecologie et dynamique des systèmes anthropisés, CNRS/Université of Picardy Jules Verne) 1 , has published the first global risk assessment for tree species planted in cities in the curre

Until now, it has been assumed that the oxygenation of the oceans over geological timescales has mainly been driven by atmospheric oxygen levels. However, a new study published in Nature June 27 2022   suggests otherwise. Work by scientists at the Biogeosciences Laboratory (CNRS/UBFC), together with their colleagues at the University of California's Department of Earth and Planetary Sciences, shows that the movement of tectonic plates has probably contributed to ocean oxygenation.

Some endocrine disruptors have already been associated with an impaired quality of tooth enamel. After demonstrating the harmful effects of bisphenol A on tooth development, a team of researchers from Inserm, Université Paris Cité and Sorbonne Université, at the Cordeliers Research Center in Paris, in collaboration with CNRS went on to look at the effects of DEHP, an endocrine disruptor in the phthalate family, on dental development.

Global climate change is particularly noticeable in the Arctic since it is warming twice as fast as temperate regions.

The 2022 Paname initiative 1 aims to better understand the causes and effects of climate change in urban environments through intensive measurement campaigns planned for the Paris region this summer. From the studies, information will be derived that is key to making cities more resilient to future climate realities.

A major contributor to climate change, methane (CH4) has a global warming potential approximately 30 times higher than that of CO2, over a 100-year period. One quarter of anthropogenic emissions of this greenhouse gas originate in worldwide extraction of coal, oil, and natural gas (of which methane is the main component).
