A new technology to secure integrated systems and circuits
The Laboratoire d'informatique, de robotique et de microélectronique de Montpellier (LIRMM) (CNRS/Université Montpellier 2) has recently developed a new technology capable of reducing data leakage fr

A supergene to stay alive
A supergene to stay alive
Some butterflies rely mainly on colorful wing patterns for their survival. CNRS researchers from the Centre d'Écologie Fonctionnelle et Évolutive (CNRS / University of Montpellier / Paul-Valéry University / EPHE-PSL / IRD), together with British and American teams, studied the genomes of dozens of tropical Heliconius numata butterflies to understand how such diversity in color motifs has come about.

Discovery of the first body in the Solar System with an extrasolar origin
Discovery of the first body in the Solar System with an extrasolar origin
Asteroid 2015 BZ509 is the very first object in the Solar System shown to have an extrasolar origin. This remarkable discovery was made by CNRS researcher Fathi Namouni and her Brazilian colleague Helena Morais, and is published on 21 May 2018 in MNRAS . Could some bodies in our Solar System come from the vicinity of other stars' Astronomers are in disagreement about comets, with some arguing that certain comets may have formed around other stars before being captured by the Sun, although they have never been able to prove it.

The survival of sea birds affected by ocean cycles
The survival of sea birds affected by ocean cycles
In a general context of climate change, researchers at the Centre d'écologie fonctionnelle et évolutive (CNRS/Université de Montpellier/Université Paul Valery/EPHE-PSL) and their international partners revealed the impact of ocean cycles, such as the Pacific decadal oscillation and El Niño, on the survival of the Nazca booby, a species found on the Galapagos Islands.

Fish in schools can take it easy
Fish in schools can take it easy
Using a new computer model, researchers at the Ecole Centrale de Marseille and CNRS have shown that a fish expends less energy when it swims in a school, because neighbouring fish produce a 'suction' effect. This work will be published on 11 May 2018 in Physical Review Letters . Schools of fish provide a fascinating example of collective behaviour in which the group moves in a coordinated manner without the need for a leader.

The Big Bell Test : participatory science puts quantum physics to the test
The Big Bell Test : participatory science puts quantum physics to the test
Quantum chance is intrinsically different than classic chance. That is what the violations of Bell inequalities, a crucial step in understanding quantum mechanics, states. One drawback remains though: until now, testing these inequalities relied on experimental configurations that use parameters set from data generated by quantum systems.

Why plants are so sensitive to gravity : The lowdown
Why plants are so sensitive to gravity : The lowdown
Plants can detect the slightest angle of inclination. Yet the mechanism by which they sense gravity relies on microscopic grains. In theory, such a system should hardly allow for precise detection of inclination. Researchers from the CNRS, the French National Institute of Agronomic Research (INRA), and Université Clermont Auvergne have now explained this curious paradox.

The laws of star formation challenged
The laws of star formation challenged
An international team led by researchers at CNRS, Université Grenoble Alpes and the French Alternative Energies and Atomic Energy Commission (CEA) has challenged currently held ideas about star formation. The unprecedented resolution of the observations obtained using the Atacama Large Millimetre/Submillimetre Array (ALMA) enabled them to measure the quantity of high-mass star-forming cores in a remote, very active region of our Galaxy, and show that there is a higher proportion of them there than expected.

Double trouble for a coral reef
Double trouble for a coral reef
Upolu, one of the nine islands of Samoa, in the Pacific Ocean. Well-known among fans of diving, this isolated coral reef promised to be a site of rich biodiversity for the scientists on the Tara Pacific expedition, principally from the CNRS, the CEA 1 and the King Abdullah University of Science and Technology (KAUST) in Saudi Arabia.

The dinosaur menu, as revealed by calcium
The dinosaur menu, as revealed by calcium
By studying calcium in fossil remains in deposits in Morocco and Niger, researchers have been able to reconstruct the food chains of the past, thus explaining how so many predators could coexist in the dinosaurs' time.

Cheaper, less toxic and recyclable light absorbers for hydrogen production
Cheaper, less toxic and recyclable light absorbers for hydrogen production
Mimicking photosynthesis in plants, using light to convert stable and abundant molecules like water and CO2 into a high energy fuel (hydrogen) or into chemicals of industrial interest, is a major research challenge today.

The largest catalog ever published of very high energy gamma ray sources in the Galaxy
The largest catalog ever published of very high energy gamma ray sources in the Galaxy
The HESS international collaboration, to which CNRS and CEA contribute, has published the results of fifteen years of gamma ray observations of the Milky Way. Its telescopes installed in Namibia have studied populations of pulsar wind nebulae and supernova remnants, as well as microquasars, never before detected in gamma rays.

Eating less enables lemurs to live longer
Eating less enables lemurs to live longer
Chronic caloric restriction strongly increases the lifespan of a small primate, the grey mouse lemur. This is one of the results of a ten-year experiment conducted by researchers at the CNRS and the French National Museum of Natural History (MNHN), in partnership with other French teams. Chronic caloric restriction consists in eating a reduced but balanced diet from the outset of early adulthood.

The great acceleration reaches new heights
An international team of researchers 1 , including a CNRS researcher at the department of Écologie et Dynamique des Systèmes Anthropisés (CNRS / Université de Picardie Jules Verne) has observed an acceleration in the increase of biodiversity on mountain peaks in Europe.

Polymers that mimic chameleon skin
Polymers that mimic chameleon skin
Biological tissues have complex mechanical properties – soft-yet-strong, tough-yet-flexible – that are difficult to reproduce using synthetic materials. An international team has managed to produce a biocompatible synthetic material that replicates tissue mechanics and alters color when it changes shape, like chameleon skin.

BIABooster : a more sensitive device for characterizing DNA in blood circulation
BIABooster : a more sensitive device for characterizing DNA in blood circulation
Developed and patented 1 in 2012 and 2014 in the Laboratoire d'Analyse et d'Architecture des Systèmes (LAAS-CNRS) and implemented industrially by Picometrics-Technologies, BIABooster technology can characterize DNA with new precision and sensitivity. When used to analyze residual DNA circulating in the blood, it has identified promising signatures for monitoring patients with cancer.

How to make a good impression when saying hello
How to make a good impression when saying hello
You can hear the perfect hello. And now you can see it too. Researchers from the CNRS, the ENS, and Aix-Marseille University 1 have established an experimental method that unveils the filter—that is, mental representation—we use to judge people when hearing them say a word as simple as “hello”. What is the ideal intonation for coming across as determined or trustworthy? This method is already used by these researchers for clinical purposes, with stroke survivors, and it opens many new doors for the study of language perception.

Quantum devices revolutionise infrared detection
A research team from the Materials and Quantum Phenomena Laboratory (MPQ, University of Paris Diderot/CNRS) has just developed a new ultra-fast photonic device that operates at room temperature, enabling the detection of infrared radiation. This scientific advance will revolutionise the use of far infrared radiation in our daily lives.

Artificial bio-inspired membranes for water filtration
Artificial bio-inspired membranes for water filtration
Access to clean drinking water is considered to be one of the main challenges of the 21st Century, and scientists have just opened a path to new filtration processes. Inspired by cellular proteins, they have developed membranes with asymmetric artificial channels in the interior, from which they were able to observe “chiral” water 1 .
