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.

Two proteins join forces to make flowers
What mechanisms are behind the formation of flowers? To answer this question a 25-year-old enigma has just been solved: the role of UFO protein in the flower's formation process. While its nature suggested that it destroys its partners, this protein is in fact an aid to the birth of a flower when coupled to the LEAFY protein.

Lepista flaccida , an edible mushroom found in the northern hemisphere, was the focus of research by French teams into ways of correcting certain genetic mutations known as nonsense mutations. MNHN/CNRS - Christine Bailly A molecule obtained from an edible mushroom could open up therapeutic avenues for patients with cystic fibrosis, the most frequent rare genetic disease.
Discovery of a circovirus involved in human hepatitis
Scientists from the Institut Pasteur, Necker-Enfants Malades Hospital (AP-HP), Inserm in the Imagine Institute, Université Paris Cité and the Alfort National Veterinary School (EnvA) have identified a previously unknown species of circovirus, provisionally named human circovirus 1 (HCirV-1). Circoviruses are a family of small, highly resistant DNA viruses that were initially identified in 1974 in various animal species, where they can cause respiratory, renal, dermatological and reproductive problems.

Dengue and Zika Viruses: Towards a Better Understanding of the Mechanisms of Transmission
The Aedes aegypti mosquito is the main vector of dengue, Zika virus infection, chikungunya, and yellow fever. © Adobe Stock Aedes mosquitoes are the principal vectors of dengue and other arboviruses, including Zika, for which no vaccines or antiviral treatments currently exist. Understanding the factors that influence the transmission of arboviruses from mosquitoes to humans is therefore a priority because it could guide the implementation of public health measures that could limit or even prevent epidemics.

Reproductive Life Factors and Hormone Therapy May Affect Women’s Risk of Parkinson’s Disease
The specific risk factors for the development of Parkinson's disease in women remain little studied and poorly known. Exposure to the hormones involved in female reproductive life is one of the avenues explored at the Epidemiology and Population Health Research Center (CESP) by a research team from Inserm, Université Paris-Saclay, Université de Versailles Saint-Quentin-en-Yvelines with Institut Gustave Roussy, which compared the reproductive characteristics of nearly 1,200 women with Parkinson's disease with those of other women from the E3N cohort .

The team from the Human Genetics of Infectious Diseases Laboratory of the Necker-Enfants malades AP-HP Hospital, Inserm, Université Paris Cité within the Imagine Institute, leading the international consortium COVID Human Genetic Effort ( www.covidhge.com ) coordinated by Prof. Jean-Laurent Casanova and Prof. Laurent Abel, has discovered genetic defects responsible for multi-systemic inflammatory syndrome in children (MIS-C), following infection with SARS-CoV-2.
Dietary Exposure to Nitrites Associated with Increased Type 2 Diabetes Risk
In addition to their role in food preservation, nitrites and nitrates give a pink color to ham and other processed meat products. © Adobe Stock More than 15,000 packaged products on the French market currently contain nitrites or nitrates. Although commonly used to ensure better preservation of processed meats (ham, sausages, etc.), the safety of these food additives is the subject of debate.

Pressing the gas pedal and lifting the brake at the same time is the innovative idea of Dr. Nicolas Manel, Inserm researcher and team leader at the Institut Curie (Immunity and Cancer Unit - Institut Curie, Inserm) to improve the response to immunotherapies. For several years, the researchers have identified a signaling pathway - STING - that is essential for accelerating the response to immunotherapies.
Emulsifiers are food additives used to improve the texture and extend the shelf life of foods. They are found in many processed foods (ice creams, packaged cakes, sauces..), although their harmful effects on intestinal balance have been demonstrated. In a new study, scientists from Inserm, CNRS and Université Paris Cité at the Cochin Institute in Paris aimed to counteract the deleterious effects induced by the consumption of emulsifiers by fortifying the intestinal epithelium via its repopulation by a bacterium naturally present in the intestine: Akkermansia muciniphila .
ChatGPT: A Technological Breakthrough?
GPT Chat is the latest innovation in chatbots. Designed by OpenAI, GPT Chat uses one of the most advanced language processing models available to simulate a natural conversation with users. GPT Chat is able to adapt to a wide range of conversational topics and provide smooth, natural responses through its use of the GPT-3 (Generative Pre-training Transformer 3) model.

Anxiety disorders are the most common psychiatric conditions in adolescence, with nearly one in three individuals affected. Adobe Stock Anxiety disorders are the most common psychiatric conditions in adolescence, with nearly one in three individuals affected. Some of these disorders - such as panic disorder or generalized anxiety disorder - tend to emerge slightly later in life or consolidate in early adulthood.
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.
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.
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.

Omar Lopez sur Unsplash In the weeks that follow the birth of a child, both parents are likely to develop depression. Paternity leave, recognized for its benefits on family balance, child development and male-female equality, could be one of the keys to preventing this condition that affects one in ten fathers and almost two in ten mothers.
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.
