Novel mutation associated with alternating hemiplegia of childhood
Novel mutation associated with alternating hemiplegia of childhood
Scientists at Trinity College Dublin and the Institute Imagine at Necker Hospital, Paris, announced a significant advance in our understanding of a very rare condition called alternating hemiplegia of childhood (AHC). This is a devastating condition that can lead to repeated paralysis that affects one side of the body or the other or sometimes both at once.

Regeneration is not a simple repetition of development
Publication of the IGFL in the journal PNAS . CNRS-INSB communication on July 12, 2022. Some organisms have the fascinating capacity to regenerate lost body parts. To which extent regeneration entails the redeployment of an embryonic developmental program is a long-standing question of regenerative studies, with implications for development, evolution, and regenerative medicine.

CEA-Leti Barn-Owl Inspired, Object-Localization System Uses Up to ’5 Orders of Magnitude’ Less Energy than Existing Technology
GRENOBLE, France - July 7, 2022 - Inspired by the barn owl's neuroanatomy, CEA-Leti has developed an event-driven, object-localization system that couples state-of-the-art piezoelectric, ultrasound transducer sensors to a neuromorphic, resistive memories-based computational map. Presented in a paper published recently in Nature Communications , the research team describes development of an auditory-processing system that increases energy efficiency by up to five orders of magnitude compared to conventional localization systems.

Highly Effective Memory B Cells Localized in the Lungs
How can we increase the efficacy of vaccines used to protect against viral respiratory diseases such as influenza and COVID-19? Scientists from Inserm, CNRS and Aix-Marseille Université at the Center of Immunology Marseille-Luminy are opening up new prospects in the field, with the triggering of memory B cells directly in the lungs looking to be a promising avenue.

Australopithecines in South Africa are older than previously thought
Australopithecines in South Africa are older than previously thought
Australopithecus africanus individuals lived at least one million years earlier than previous dating indicated. This is the result from dating a cave deposit from the Sterkfontein site (South Africa), one of the richest in australopithecine remains, where the fossil of Mrs Ples, one of the first complete skulls of this kind of hominin, was discovered in 1947.

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

In France, one adult out of four is affected by some form of hearing loss
In France, one adult out of four is affected by some form of hearing loss
Hearing loss is a public health problem affecting billions of people in all countries. However, prevalence data (i.e., schematically, their frequency in the population), as well as data describing the use of hearing aids, remain imprecise. A new study conducted by a research team from Inserm and Université Paris Cité at PARCC (Paris Cardiovascular Research Center, unit Inserm Unit 970) , in collaboration with the AP-HP and the Foch Hospital in Suresnes, shows for the first time that 25% of adults in France are affected by some form of hearing impairment.

Researchers described how the cerebellum modulates our ability to socialize
The cerebellum is essential for sensorimotor control but also contributes to higher cognitive functions including social behaviors. In a recent study, an international research consortium including scientists from Inserm – University of Montpellier (France), the Institut de Neurociències Universitat Autònoma de Barcelona (INc-UAB) (Spain), and the University of Lausanne (Switzerland) uncovered how dopamine in the cerebellum modulates social behaviors via its action on D2 receptors (D2R).

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.

Ensuring pollen survival: When putting on your coat becomes a collaborative activity
Publication of the RDP in the journal PNAS on May 24, 2022. CNRS-INSB communication on May 30, 2022. Pollen viability depends on a tough external barrier called the pollen wall. Pollen wall components are produced by tapetum cells, which surround developing pollen grains within the anther. Precise coordination of tapetum activity with pollen grain development is required to ensure effective pollen wall formation.

Excavation of a modern and modern cemetery in the heart of Colmar (Haut-Rhin)
Excavation of a modern and modern cemetery in the heart of Colmar (Haut-Rhin)
In Colmar, the Inrap is excavating the cathedral square and uncovering the old cemetery of the Saint-Martin collegiate church. The initial research provided first-rate information on the population of Colmar in the medieval period. In the heart of the city, the redevelopment project of the Cathedral Square, carried by the City of Colmar, has motivated the prescription of a preventive archaeological excavation by the State (Drac Grand-Est).

Do Some Cognitive Biases Contaminate Even Our Simplest Mental Mechanisms?
When we implement complex cognitive processes, for example when making decisions, we are subject to cognitive bias. But what about simpler processes, such as those involved in the most basic learning? In a new study analyzing data from all previous research in the field, researchers from Inserm and ENS-PSL show that not only are positivity and confirmation biases present even in the simplest human and animal cognitive processes, but also that incorporating them into learning algorithms would enhance their performance.

Women-specific mechanisms may contribute to tumor progression
Researchers have demonstrated the role of a non-coding RNA in the development of aggressive tumors, particularly in breast cancer. The study, conducted in collaboration between the Institut Curie, Inserm, CNRS, Institut Paoli Calmettes and Aix-Marseille University , has just been published in the journal Cell .

Phage Therapy: A Model to Predict Its Efficacy against Pathogenic Bacteria
Antibiotic resistance represents a major public health challenge, associated with a high mortality rate. While bacteriophages - viruses that kill bacteria - could be a solution for fighting antibiotic-resistant pathogens, various obstacles stand in the way of their clinical development.

First image of the black hole at the heart of our galaxy
First image of the black hole at the heart of our galaxy
Within the EHT collaboration, the CNRS and IRAM participated in the creation of a first image of the black hole Sagittarius A*. Astronomers have unveiled the first image of the supermassive black hole at the centre of our own Milky Way galaxy. This result provides overwhelming evidence that the object is indeed a black hole and yields valuable clues about the workings of such giants, which are thought to reside at the centre of most galaxies.

Healthy cells can impact tumour progression during embryonic development
Healthy cells can impact tumour progression during embryonic development
Half of childhood cancers arise during the development of the human embryo, which greatly complicates research into these diseases. The team of Valérie Castellani, CNRS senior researcher at the Mechanisms in Integrated Life Sciences (MeLiS) laboratory (CNRS / INSERM / Claude Bernard Lyon 1 University) has thus developed a model that optimally simulates the human embryonic environment by grafting human cancer cells into a chick embryo.

Influenza: A New Avenue for Developing Innovative Treatments
Influenza: A New Avenue for Developing Innovative Treatments
Seasonal influenza is a major public health issue because it continues to remain associated with considerable mortality, particularly among people who are elderly, immunocompromised, or both. It also has a significant socioeconomic cost. With vaccination and current treatments still being of limited efficacy, research teams are trying to develop new therapeutic approaches.
