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.

Bocage landscapes to promote plant diversity in cultivated fields
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.

What causes cod stock collapse: climate-induced environmental change or fishing?
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 combat the effects of climate change
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.

Climate change: a threat to urban trees
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

Plate tectonics drives ocean oxygenation
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.

Even at Low Doses, Exposure to the Endocrine Disruptor DEHP Impairs Tooth Development
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.

Paname 2022: campaigns to study air quality and urban climate
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.

Massive methane emissions by oil and gas industry detected from space
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).

Cyclists and Pedestrians Inhale More Road Traffic Particles Than Motorized Transport Users
Users of different transport types breathe in over twice the dose of black carbon per 30-minute period when traveling compared with when not traveling (when at home or at work, for example). Unsplash The measurements of individual exposure to pollution, which are generally taken at the place of residence, overlook two major parameters: the much higher exposure occurring during travel and the variations in air volumes, and consequently the varying levels of air pollutants, which are inhaled according to the intensity of physical exertion involved by the journey.

Reducing air pollution: policies that pay off
Every year in France, fine particle pollution (particles with a diameter of less than 2.5 micrometres 1 ) leads to the premature death of around 40,000 people. The associated cost is estimated at €100 billion per year. Despite this, public policies to combat air pollution are generally implemented without first assessing their future health and economic impacts.

Microplastic discovered in ’pristine’ Pyrenees mountain air
Previously detected in rivers, oceans, and snow, 1 microplastic has now been found in the high-altitude air surrounding the Pic du Midi (2,877 m)-by an international research team including scientists from the CNRS, Université Grenoble Alpes, 2 and the University of Strathclyde (Scotland).

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.

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.
