La résistance antimicrobienne est la capacité des micro-organismes à résister aux traitements antimicrobiens, en particulier aux antibiotiques. Faisant 33 000 victimes dans l’Union européenne chaque année, elle pourrait devenir une cause de décès plus importante que le cancer d’ici à 2050. Des chercheurs suisses apportent une lueur d’espoir dans ce

Le ministre de l’économie Bruno Lemaire a annoncé ce 8 janvier, contre toute attente, son intention de ne pas interdire l’additif alimentaire E171 plus communément connu sou le nom de dioxyde de titane. La décision est reportée à plus tard, quand les preuves scientifiques seront réunies de la dangerosité de

Did you say "nano"? It's often difficult to imagine a grain of matter at the nanoscale: a billionth of a metre. To get an idea of this, let's point out that the size ratio between planet Earth and an orange is similar to that between an orange

Scientists at the University of Lincoln in the United Kingdom have developed a new technique to coat gold nanoparticles with a specific protein so that they can be used to address a drug that will target a specific area of the body, such as a cancerous tumour, very precisely. Gold nanoparticles are

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.

On 7 June 2017, the NanoRESP Forum addressed the issue of "nanofree" demand, i.e. products that intentionally do not contain or are intentionally deprived of manufactured nanomaterials. Against a backdrop of uncertainty about the dangers of certain nanoparticles (see box), this subject has become topical with the initiatives of the Friends of

Une étude réalisée par des scientifiques britanniques vient d’être publiée dans les Actes de l’Académie Nationale des Sciences, et elle fait froid dans le dos. Des nanoparticules toxiques liées à la pollution de l’air viennent en effet d’être trouvées « en quantité abondante » dans les tissus du cerveau ; elles pourraient être

Filter membranes with micropores tend to spread to provide drinking water or to desalinate sea water. Nanostructured filter materials are being considered to complement these devices; for example, to filter pesticide and drug residues or to clean up water tables. The expected efficiency gain

In 1966 Richard Fleischer's Le Voyage Fantastique miniaturized matter to resorb a blood clot in the brain of an eminent American scientist via the micro-submarine "Proteus" injected into his bloodstream. At the end of October 2014 Google X Lab announces the development of a research project on nanoparticles that will allow the
