Pendant des années, l’Union européenne a imposé des restrictions parmi les plus strictes du monde à l’agriculture génétiquement modifiée. Cela pourrait être sur le point de changer. En effet, les européens ont vécu leur pire été en termes de sécheresse. Les fleuves comme la Loire se sont retrouvés taris, les

Cela fait dix ans que les scientifiques ont mis au point CRISPR, une technologie permettant d’apporter des modifications ciblées à l’ADN des cellules, mais jusqu’à présent, la méthode n’a été testée que sur des personnes souffrant de maladies rares comme la drépanocytose, et uniquement dans le cadre d’essais exploratoires. Une

Les catastrophes climatiques, les retombées de la pandémie et la guerre en Ukraine constituent une triple combinaison toxique pour la sécurité alimentaire. Un récent rapport mondial a estimé que le nombre de personnes en crise alimentaire a doublé depuis 2016. Le problème est exacerbé par l’augmentation des coûts des engrais

Aujourd’hui en France, et contrairement à ce que l’on peut croire, l’agriculture représente l’un des secteurs les plus connectés. Très dépendante de la météorologie, l’agriculture doit se réinventer. Victimes du réchauffement climatique et de la crise sanitaire, de grands enjeux attendent désormais les agriculteurs dans le futur : entre nouvelles

Si l’on pouvait tester facilement le maximum de personnes, la crise du Covid deviendrait sans doute un mauvais souvenir. Mais nous butons sur les tests. Trop complexes à mettre en œuvre, longs à fournir des résultats, inégaux dans leur fiabilité. La solution pourrait venir de CRISPR, ces fameux ciseaux moléculaires

Le prix Nobel de chimie 2020 vient d’être attribué. Il récompense Emmanuelle Carpentier et Jennifer Doudna, une chercheuse française et l’autre américaine, pour leur invention de l’outil d’édition du génome CRISPR-Cas9. Dès son apparition, ce « couteau suisse » de l’édition de la vie a suscité un engouement extraordinaire. Des milliers d’applications

How do you protect crops from diseases, insects and other pests when pesticides have a serious sulphur smell? Scientific research proposes to modify plants using genetic editing resources. Biotechnology advocates swear that these modified plants are not GMOs and

A group of German Green MEPs supports the use of genetic engineering techniques, which they believe could make a significant contribution to sustainable development. This is a novel approach that runs counter to the position that environmentalists usually take on this subject. In a forum on 10 June, the 22 signatories - who

The Chinese twins born last year from embryos genetically modified by the "CRISPR" molecular scissors probably have unexpected mutations in their genome as a result of this manipulation. This information was revealed by an American journalist on December 3 after obtaining an unpublished version of the study detailing the experiment.

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.

Mars seems to have become the latest fashionable destination. There is no shortage of projects and candidates for the long journey are jostling for the gate. It must be said that the first organized trip is for - almost - tomorrow: 2024. That's what Elon Musk predicts, ready to embark.

The information was published in China in the Beijing National Science Review on March 27 and revealed to the world by the MIT Review today, April 10. Chinese geneticists are believed to have succeeded in introducing copies of a human gene suspected of playing a role in the development of the brain of monkeys.

It is a race against time that is being played out in Australia, as in other parts of the world. Coral reefs, shelters of marine biodiversity, are disappearing at a glance. If global temperatures continue to rise to 2°C, half of the world's coral reefs will be destroyed.

The information had been around the world last November. A Chinese researcher, Jiankui He, alone in his laboratory, reportedly delivered the first two genetically modified babies. Using the CRISPR molecular scissors, he would have intervened on certain genes to prevent these babies from getting HIV.

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 mastery of CRISPR, this overpowering tool of genetic manipulation, is making progress every day, leading us into increasingly worrying territories. American scientists announce that they have succeeded for the first time in modifying the hereditary traits of a mammal. Mice have been treated with

Thanks to CRISPR, this Chinese researcher was able, almost alone, to produce genetically modified babies. The information went around the world in just a few hours: a Chinese researcher announced this week that he had been able to deliver two genetically modified babies. A world premiere that has propelled
