Breast cancers: ruptures in cell nuclei promotes tumor invasion
Breast cancers: ruptures in cell nuclei promotes tumor invasion
Cell nuclei protect the DNA. Nuclei can rupture when cells are deformed, causing DNA damage. In the case of breast cancer, this damage makes tumour cells more invasive, with increased risk of metastasis. When cells multiply and migrate, they can be compressed and their nucleus may break open. This phenomenon causes DNA damage.

COVID-19: Will telecommuting strategies stop the virus from circulating?
How can we best organise on-site workplace and school attendance periods and remote work to slow the circulation of Sars-CoV-2? Is it better to separate classes? Bring your whole team in at the same time? Set this up on daily or weekly schedules? The COVID-19 pandemic has forced most countries to impose contact limitations in workplaces, universities and schools.

Neandertal and Denisovan blood groups deciphered
Neandertal and Denisovan blood groups deciphered
The blood groups of three Neandertal females and one Denisovan female have been determined by a Marseille-based team including a palaeoanthropologist, population geneticists, and haematologists. Their research provides new data for understanding the origins, history, and health of these extinct hominin lineages.

Optogenetic Methods Restore Partial Vision in a Blind Patient
Optogenetic Methods Restore Partial Vision in a Blind Patient
Results of this research, a world-first, were published in  Nature Medicine on May 24th, 2021. An international research team has shown that optogenetic therapy has helped a patient with retinitis pigmentosa to partially regain visual function. This is a milestone step towards a type of gene therapy that could restore vision.

A protein with a dual role: both repair and mutation
A protein with a dual role: both repair and mutation
The Mfd protein repairs bacterial DNA, but can also, to scientists' surprise, promote mutation. Bacterial mutations can lead to antibiotic resistance. Understanding this second "role" of the Mfd protein opens up opportunities for combating antibiotic resistance, and also the resistance of tumours to anti-cancer drugs and therapies.

Targeting Cancer Detection & Identification of Microorganisms, CEA-Leti Develops Mid-Infrared, Spectral-Imaging Technique
Presentations at Photonics West 2021 Show How Early-Stage Imaging System's Flexibility Can Be Applied Broadly in Medical Field GRENOBLE, France - March 18, 2021 - CEA-Leti scientists have developed a lensless, infrared spectral-imaging system for medical diagnostics. The first application is cancer detection in the tissue section and the second is the identification and discrimination of microorganisms, such as bacteria.

COVID-19 Screening: A New Model for Assessing the Efficiency of Group Testing
COVID-19 Screening: A New Model for Assessing the Efficiency of Group Testing
How best to evaluate the performance of a group testing strategy for the SARS-CoV-2 virus, which involves pooling samples from multiple individuals in order to conduct a single RT-PCR test on the whole group? To do precisely that, scientists from the CNRS, l'université Grenoble Alpes, and l'université Sorbonne Paris Nord 1 have developed a model that evaluates the efficiency of such tests.

Heat islands and lack of running water promote dengue fever in Delhi, India
Heat islands and lack of running water promote dengue fever in Delhi, India
What if more inclusive urban planning for poor populations was key to fighting dengue fever? This is what researchers from the CNRS, the Institut Pasteur and the Indian Council of Medical Research 1 have demonstrated using a geographical approach applied to the greater city of Delhi (India). Their study is published in the journal PLOS Neglected Tropical Disease on 11 February 2021.
