Researchers from Inserm have developed a pulmonary valve using human collagen. A device that could ultimately be a game-changer in the treatment of paediatric heart diseases, such as tetralogy of Fallot. These findings form part of broader research conducted at BioTis (Inserm/Université de Bordeaux), a tissue bioengineering lab in Bordeaux which develops tissues made from biological material obtained from human cells.
Why does some music make us want to dance more than others? This is the question that a research team from Inserm and Aix-Marseille Université tried to answer by studying the desire to dance (also called the 'groove') and the brain activity of 30 participants who were asked to listen to music. Their findings show that the groove sensation is highest for a moderately complex rhythm and that the desire...
One in three French adults is thought to have a sleep disorder. While the prevalence of these disorders increases with age, the biological mechanisms at play are relatively unknown, leaving scientists in doubt as to their origin. In a new study, Inserm researcher Claude Gronfier and his team at the Lyon Neuroscience Research Center (Inserm/CNRS/Université Claude-Bernard Lyon 1) hypothesised that their onset during ageing was linked to a desynchronisation...
urrently, the treatment of heart valve diseases relies on the replacement of the dysfunctional valve with an artificial prosthesis. However, this procedure cannot be offered to all patients due to its invasive nature. In a new study, a group of researchers from laboratories shared by Inserm, ESPCI Paris, CNRS and Université Paris Cité, in close collaboration with the start-up Cardiawave spin-off of the Georges Pompidou European Hospital and the...
We are all familiar with taking our pulse to check our heart rate. This signal is due to the propagation of a wave caused by the arteries dilating under the surge of blood from the heart.
Restaurer la vision grâce à une thérapie associant génétique et ultrasons ? Tel est l’objectif poursuivi par une équipe internationale dirigée par les directeurs de recherche Inserm Mickael Tanter et Serge Picaud, associant respectivement le laboratoire Physique pour la médecine (ESPCI Paris/PSL Université/Inserm/CNRS) et l’Institut de la vision (Sorbonne Université/Inserm/CNRS) à Paris en partenariat avec l’Institut d'ophtalmologie moléculaire et clinique de Bâle. Dans une nouvelle étude, ils ont apporté la...
Mieux comprendre divers processus invisibles à l’œil nu, qui ont lieu à l’échelle de nos cellules, grâce à un minuscule robot construit à base d’ADN... Si cela s’apparenterait presque à un projet de science-fiction, il s’agit en fait de travaux très sérieux menés par des scientifiques. Ce « nano-robot », très innovant, devrait permettre d’étudier de plus près des forces mécaniques qui s’appliquent à des niveaux microscopiques et qui sont cruciales...
Our ability to understand the syntax of complex sentences is one of the most difficult language skills to acquire. In 2019, research had revealed a correlation between being particularly proficient in tool use and having good syntactic ability. A new study has now shown that both skills rely on the same neurological resources, which are located in the same brain region. Furthermore, motor training using a tool improves our...
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.
For the past 30 years, it was thought that the brain – responsible for motor control – worked to continuously compensate for the effects of gravity. In an initial study in 2016, the researchers had suggested that our brains use gravity to minimize the effort our muscles have to make. Those results were recently confirmed by new experiments conducted in collaboration with New York University on non-human primate models...
