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.

Cyclones starve North Atlantic seabirds
Cyclones starve North Atlantic seabirds
Every winter, thousands of emaciated seabird carcasses are found on North American and European shores. In an article published on the 13 September in Current Biology , an international team of scientists including the CNRS 1 has shown how cyclones are causing the deaths of these birds. The latter are frequently exposed to high-intensity cyclones, which can last several days, when they migrate from their Arctic nesting sites to the North Atlantic further south in order to winter in more favourable conditions.

An artificial ionic neuron for tomorrow's electronic memories
An artificial ionic neuron for tomorrow’s electronic memories
Artificial intelligence surpasses the human brain only at the cost of consuming tens of thousands of times more energy. A major difference between the brain and electronic systems is that neurons use ions, not electrons, to carry information. French scientists have designed theoretical artificial neurons with ions to carry the information.

Bird and mammal diversity is declining with biological invasions
Bird and mammal diversity is declining with biological invasions
Biological invasions are one of the most important factors of biodiversity loss. They threaten the diversity of ecological strategies - the ways in which species feed, live, function and defend themselves - by up to 40% in birds and 11% in mammals. 11% of the evolutionary diversity of birds and mammals, i.e. their accumulated evolutionary history, is also threatened by biological invasions.

ALPALGA: the search for mountain snow microalgae
ALPALGA: the search for mountain snow microalgae
High elevation snow is home to previously unknown species of microalgae. Scientists have created the ALPALGA consortium to study this ecosystem, which is threatened by climate change. According to their initial results, these microalgae are tiered to elevation, just like herbaceous plants and trees.

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 plant-fungi partnership at the origin of terrestrial vegetation
A plant-fungi partnership at the origin of terrestrial vegetation
Plants that exist on land today have genes that allow them to exchange lipids with beneficial fungi This plant-fungus partnership is at the origin of the transition of plants from aquatic life to terrestrial life 450 million years ago, the first plants left aquatic life. Researchers from the CNRS and the Université de Toulouse III - Paul Sabatier, in collaboration with INRAE, have succeeded in demonstrating that this colonisation of land by plants was made possible by a partnership between plants and fungi.

In the Alps, climate change affects biodiversity
In the Alps, climate change affects biodiversity
The European Alps is certainly one of the most scrutinized mountain range in the world, as it forms a true open-air laboratory showing how climate change affects biodiversity. Although many studies have independently demonstrated the impact of climate change in the Alps on either the seasonal activity (i.e.

'All-in-One' Technique that Could Accelerate Phage-Therapy Diagnosis
’All-in-One’ Technique that Could Accelerate Phage-Therapy Diagnosis
Lensless Imaging System Affirms Phage Therapy's Value in Treating Serious Infection, Tracks Phage Resistance and Could Easily Be Implemented in Compact Devices at Phage Labs GRENOBLE, France - April 13, 2021 - A team of French and Swiss scientists has demonstrated a lensless imaging technique that could easily be implemented in cost-effective and compact devices in phage laboratories to accelerate phage-therapy diagnosis.

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.

A brain signature that predicts vulnerability to addiction
A team of neurobiologists at the Institut de Neurosciences de la Timone (CNRS/Aix-Marseille Université) has just shown that within a population of rats it can predict which will become cocaine addicts. One of the criteria for addiction in rats is the compulsive search for a drug despite its negative consequences.

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.

Discovery of a 'winged' shark in the Cretaceous seas
Discovery of a ’winged’ shark in the Cretaceous seas
The fossil of an unusual shark specimen reminiscent of manta rays sheds light on morphological diversity in Cretaceous sharks. This plankton feeder was discovered in Mexico and analysed by an international team of palaeontologists led by a CNRS researcher from Géosciences Rennes 1 (CNRS/University of Rennes 1).
