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

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

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

Antibiotic resistance - the phenomenon whereby bacteria stop responding to certain antibiotics - is a growing threat worldwide. A threat that is expected to kill 10 million people a year by 2050. Many major pharmaceutical companies have stopped developing antibiotics.

Are the technologies developed in semiconductors transposable to medicine? This is what IBM Research, associated for the occasion with a bio and nano technology institute in Singapore, is trying to prove. Their work has just been published in a scientific journal. The researchers claim to have created a macromolecule capable of eradicating

Biodiversity is currently undergoing one of its most significant alterations: the current extinction rates of animal species are 100 to 1,000 times higher than those recorded from fossil records. They concern all types of species - birds, reptiles, mammals. The primordial role of human activities in this phenomenon
