A considerable fraction of the population is reluctant to get vaccinated against COVID-19. French scientists have designed a chatbot that offers personalised responses to questions posed by the curious or hesitant-and have demonstrated its effectiveness. What if a few minutes of interaction with a chatbot could effectively address vaccine concerns? In an article published in the Journal of Experimental Psychology: Applied (28 October 2021), researchers from the CNRS, INSERM, and ENS-PSL show that such an interface is indeed capable of swaying the vaccine-hesitant.

Chatbot for addressing COVID-19 vaccine hesitancy
A considerable fraction of the population is reluctant to get vaccinated against COVID-19. French scientists have designed a chatbot that offers personalised responses to questions posed by the curious or hesitant-and have demonstrated its effectiveness. What if a few minutes of interaction with a chatbot could effectively address vaccine concerns? In an article published in the Journal of Experimental Psychology: Applied (28 October 2021), researchers from the CNRS, INSERM, and ENS-PSL show that such an interface is indeed capable of swaying the vaccine-hesitant.

New, promising opportunities for treating skin fibrosis
Skin fibrosis impairs skin tissue function, and has a strong aesthetic impact. French researchers have now shown that applying an electric field to the skin could cure skin fibrosis by reducing overly high collagen levels. Collagen, the main component of the skin's extracellular matrix, can cause a pathological condition if it is in excess.

Origin of domestic horses finally established
The modern horse was domesticated around 2200 years BCE in the northern Caucasus. In the centuries that followed it spread throughout Asia and Europe. To achieve this result, an international team of 162 scientists collected, sequenced and compared 273 genomes from ancient horses scattered across Eurasia.

A new therapeutic target to combat addiction?
A new therapeutic target to combat addiction?
Drug addiction is a psychiatric disorder for which no pharmacological treatment with long-term efficacy currently exists. All addictive substances share the property of raising concentrations of the neurotransmitter dopamine within brain regions forming the neural reward circuit. This increase in dopamine levels results in long-lasting alteration of signal transmission that is dependent on another neurotransmitter, glutamate, which causes addictive behaviours.

Climate model shows that Venus could never have had oceans
Whether Venus, one of the Solar System's four terrestrial planets, ever had oceans remains an unsolved puzzle. Although an American study hypothesized involving in particular scientists from the CNRS and University of Versailles-Saint Quentin-en-Yvelines 1 (UVSQ). Using a state-of-the-art climate model, the research team has come up with an alternative scenario to the American study.

Mars: first results from the Perseverance rover
Images from Perseverance's French-American instrument SuperCam show that the crater where the rover landed once contained a lake. The SuperCam observations also identified strata containing boulders, related to a major change in the hydrological regime. This study, led by a French researcher, will facilitate selection of the most suitable areas for Perseverance to collect samples.

Why there is hardly any dust on some asteroids
Why there is hardly any dust on some asteroids
There was a surprise in store for NASA's OSIRIS-REx spacecraft as it prepared to land on asteroid Bennu in October 2020 in order to collect samples. Contrary to what astronomers believed, the asteroid's surface was not covered with a layer of fine dust, called regolith. This dust, which blankets the Moon and some asteroids, is formed when thermal shock and meteorite impacts break up surface rocks.

First European map of the insulating effect of forests
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 that the forest canopy provides, but also by the transpiration of trees in summer: trees absorb cooler water from the soil, and this water is then transported up to the leaves, ending up in the atmosphere and thus cooling the surrounding air.

Zen stones naturally placed atop pedestals of ice: a phenomenon finally understood
Zen stones naturally placed atop pedestals of ice: a phenomenon finally understood
Like a work of art enshrined in a museum, some stones end up on a pedestal of ice in nature, with no human intervention. This "Zen stone" phenomenon, named after the stacked stones in Japanese gardens, appears on the surface of frozen lakes, Lake Baikal (Russia) in particular. These structures result from the phenomenon of sublimation, which causes a body, in this case ice, to change from solid to gaseous form without the intermediary form of a liquid.

Continental growth is not a continuous process
Continental growth is not a continuous process
One of Earth's unique features is that it has continents. Contrary to many theories, the continents have always been rich in silica (which is found in quartz for example). The continents did not form continuously over time but result from episodic events throughout Earth's history. The continents, a specific feature of our planet, still hold many secrets.

Breast cancers: ruptures in cell nuclei promotes tumor invasion
Breast cancers: ruptures in cell nuclei promotes tumor invasion
Cell nuclei protect the DNA. Nuclei can rupture when cells are deformed, causing DNA damage. In the case of breast cancer, this damage makes tumour cells more invasive, with increased risk of metastasis. When cells multiply and migrate, they can be compressed and their nucleus may break open. This phenomenon causes DNA damage.

Part of the Universe’s missing matter found thanks to the MUSE instrument
CRAL publication in MNRAS , on September 16, 2021. CNRS press release on September 16, 2021. Galaxies can receive and exchange matter with their external environment thanks to the galactic winds created by stellar explosions. Thanks to the MUSE instrument  from the Very Large Telescope at the ESO, an international research team, led on the French side by the CNRS and l'Université Claude Bernard Lyon 1 , has mapped a galactic wind for the first time.

Cyclones starve North Atlantic seabirds
Cyclones starve North Atlantic seabirds
Every winter, thousands of emaciated seabird carcasses are found on North American and European shores. In an article published on the 13 September in Current Biology , an international team of scientists including the CNRS 1 has shown how cyclones are causing the deaths of these birds. The latter are frequently exposed to high-intensity cyclones, which can last several days, when they migrate from their Arctic nesting sites to the North Atlantic further south in order to winter in more favourable conditions.

COVID-19: Will telecommuting strategies stop the virus from circulating?
How can we best organise on-site workplace and school attendance periods and remote work to slow the circulation of Sars-CoV-2? Is it better to separate classes? Bring your whole team in at the same time? Set this up on daily or weekly schedules? The COVID-19 pandemic has forced most countries to impose contact limitations in workplaces, universities and schools.

An artificial ionic neuron for tomorrow’s electronic memories
Artificial intelligence surpasses the human brain only at the cost of consuming tens of thousands of times more energy. A major difference between the brain and electronic systems is that neurons use ions, not electrons, to carry information. French scientists have designed theoretical artificial neurons with ions to carry the information.

Bird and mammal diversity is declining with biological invasions
Biological invasions are one of the most important factors of biodiversity loss. They threaten the diversity of ecological strategies - the ways in which species feed, live, function and defend themselves - by up to 40% in birds and 11% in mammals. 11% of the evolutionary diversity of birds and mammals, i.e. their accumulated evolutionary history, is also threatened by biological invasions.

Neanderthals indeed painted Andalusia’s Cueva de Ardales
The origin and date of appearance of prehistoric cave art are the subjects of ongoing debate. Spain's Cueva de Ardales is one point of discussion. There a flowstone formation is stained red in places. This colouring is apparently almost 65,000 years old 1 but until now, a part of the scientific community attributed it to a natural coating of iron oxide deposited by flowing water.
