Le virus de la grippe et le virus respiratoire syncytial (VRS) peuvent fusionner pour créer un virus capable d’échapper au système immunitaire humain. Les chercheurs, désireux de comprendre les co-infections – dans lesquelles les deux virus infectent une personne en même temps – ont délibérément infecté des cellules pulmonaires humaines

Les glaciers, tout comme le pergélisol, fondent, mis en fusion par la dégradation climatique. Un phénomène qui s’accélère et se déroule, dans plusieurs régions du monde, sous nos yeux. De la bouillasse qui en résulte, d’anciennes créatures émergent, sortant, comme dans un film d’horreur de la torpeur de leurs siècles

Des experts au Royaume-Uni ont confirmé dès le 7 mai dernier les premiers cas de variole du singe. D’habitude rares surtout en dehors de l’Afrique de l’Ouest et Centrale où le virus est endémique chez les animaux, des cas ont pourtant été signalés rapidement dans plusieurs pays. Entre les 13

The Roman Empire lasted five centuries and had a profound effect on our culture and civilization. For a long time it was believed that this Empire, seemingly indestructible, had suffered a long degradation, a decadence, until its end. However, the historians of ancient Rome are no longer wise old men, distinguished Latin scholars

Depuis maintenant un an, on ne parle que de lui… sans jamais cependant entendre son point de vue ! Franck Courchamp, directeur de recherche au CNRS, s’est glissé le temps d’une interview imaginaire dans la peau de ce coronavirus SARS-CoV-2 qui affole la planète. Au-delà de l’aspect ludique de cette

Le vaccin contre le Covid-19 de Pfizer et BioNTech semble capable de protéger contre une mutation clé des nouvelles variantes hautement transmissibles du coronavirus découvertes en Grande-Bretagne et en Afrique du Sud, selon une étude de laboratoire menée par le fabricant de médicaments américain. L’étude de Pfizer et des scientifiques

The Assembly votes on the article on the state of health emergency. Adopted by a show of hands after several hours of discussion, the article provides that a state of public health emergency, which makes it possible to restrict public freedoms (confinement, requisitioning, etc.), must be introduced as soon as the law comes into force, and for two months. This article provides, in particular, for

France is not China. Not so much because of its geographical size or economic power, but because of its culture and the way of life and behaviour of the French. The coronavirus is reshuffling the maps of the hierarchy of needs, without revolutionizing everyday habits. It is

Researchers from the Centre for Infection and Immunity in Lille (CNRS/Inserm/Institut Pasteur de Lille/University of Lille/CHU Lille) and their colleagues from INRAE have revealed for the first time in mice that disturbances in the intestinal microbiota caused by the influenza virus favour secondary bacterial superinfections. Published in the

They are as old as life itself, but scientists cannot say for sure if they are alive. Viruses are embedded in our DNA, shaping the human saga through mutation and resistance. We touch hundreds of millions of them every day. Like the new epidemic of

A research team at the University of North Carolina in the United States, led by one of the world's leading virus specialists, Professor Ralph Baric, is racing against time to artificially recreate the Chinese coronavirus (SARS-CoV-2 is its scientific name). From DNA

Between Ebola that kills and the flu that knocks us down, there is one thing in common: both diseases, like many others, are caused by an RNA virus. This type of virus is the cause of the world's most common but deadly diseases.

Their names are scary, and rightly so, because these viruses are wreaking havoc. Ebola, Zika, Dengue, Lassa, ... cause hundreds of deaths and pose a major epidemiological risk. A new hope to stop these scourges comes from the famous molecular tool CRISPR. Often criticized for its applications sometimes

The U.S. military is studying the possibility of creating a new type of biological weapon. It would involve insects selected to carry a genetically modified virus. The objective of this plan, deployed through DARPA, the U.S. Army's research agency, is to rapidly deploy this armada if critical crops for

They're big bugs, unusually big for viruses. So huge, it's a wonder they could be under the radar of scientists until... 2013. The first "pandoravirus" was spotted on a beach in Chile. Then things accelerated and we started to find one...

Doctors, scientists, the WHO and all public health organizations keep telling us this. We are on the brink of a devastating global pandemic. The question that no one can answer is that of the source of this expected and almost certain disease. Will it be

Since the dawn of time, debates and controversies have clashed over the origin of life. Scientists have just published an article accumulating evidence of an extraterrestrial origin for certain species living on Earth. This is the case for certain viruses and cephalopods that have genetic characteristics that we do not know about.

Researchers at the Swiss Federal Institute of Technology in Lausanne have developed gold nanoparticles that have the property of attracting viruses to them in order to destroy them. Like broad-spectrum antibiotics, this completely new approach could destroy several types of virus such as HIV, dengue fever, herpes or Ebola.

A research project developed by British scientists from the University of York and the University of Leeds has established how to write code that can govern the assembly of viruses. In other words, the researchers claim to be able to write code to control the
