The link between the viral variant and length of the COVID-19 incubation period is still a matter of debate. Scientists from the Institut Pasteur conducted a survey of thousands of volunteers for more than a year to provide an answer.

Type 1 diabetes, multiple sclerosis, rheumatoid arthritis, systemic lupus erythematosus, vitiligo, Crohn's disease and Guillain-Barré syndrome – these seemingly different diseases all have one thing in common: they occur when a deregulation of the immune system causes it to “attack” the body that it is supposed to be protecting.

Les liens entre la durée d’incubation de la Covid-19 et le variant du virus contaminant sont encore discutés. Des chercheurs de l’Institut Pasteur ont enquêté auprès de milliers de volontaires sur plus d’un an pour nous apporter une réponse.

Diabète de type 1, sclérose en plaques, polyarthrite rhumatoïde, lupus érythémateux disséminé, vitiligo, maladie de Crohn, syndrome de Guillain-Barré… Ces maladies apparemment bien différentes ont un point commun : elles sont dues à un dérèglement du système immunitaire, qui se met à « attaquer » l’organisme qu’il doit normalement protéger.

Scientists from the Institut Pasteur have worked in collaboration with high school students from Bondy to showcase biodiversity in an original artistic format. This Bio-Art project is the result of a scientific outreach campaign in partnership with the Institut Pasteur.

Des scientifiques de l’Institut Pasteur ont collaboré avec des lycéens de Bondy pour mettre en valeur la biodiversité sous un format artistique original. Cette opération de Bio-Art est le fruit d’une activité de médiation scientifique en partenariat avec l’Institut Pasteur.

Could there have been any doubt that babies can recognize their mother even before they are born, that they learn to speak based on the sound of the voice and express an unquenchable curiosity for faces? Four scientists spoke at the conference "What do babies think about?" organized at the Institut Pasteur for Brain Awareness Week 2023. Their presentations taught us more about the surprising abilities of the youngest among us.

Pourrions-nous nous douter que les bébés peuvent reconnaitre leur mère avant même de naitre, apprendre la parole grâce aux sons de la voix, ou encore exprimer une curiosité insatiable pour les visages ? Quatre chercheuses et chercheurs ont pris la parole lors de la conférence « A quoi pensent les bébés ? », organisée à l’Institut Pasteur, à l’occasion de la semaine du cerveau 2023. Ils nous en apprennent plus sur les étonnantes capacités de nos cadets.

Where did SARS-CoV-2 come from? How did this virus enter the human population? These questions still remain unanswered. In June 2022, a group of experts, the Scientific Advisory Group for the Origins of Novel Pathogens (SAGO) commissioned by the World Health Organization (WHO), published a report on the origin of coronavirus but was unable to draw a definitive conclusion. Since then, research has continued, particularly at the Institut Pasteur and in the Pasteur Network, to further our knowledge of SARS-CoV-2 and the evolution of the disease in a bid to better understand the origins of the pandemic. To this end, a recent study led by Institut Pasteur scientists on SARS-CoV-2-related viruses circulating among bats in Laos has concluded that it is unlikely that these viruses had acquired the same ability as SARS-CoV-2 to infect human lungs by accumulating mutations during prior silent circulation in human or intermediate host populations. This article explores their research.
