Mystery solved! We finally understand the origin of the colours in the first colour photographs
A palette of colours on a silver plate: that is what the world's first colour photograph looks like. It was taken by French physicist Edmond Becquerel in 1848. His process was empirical, never explained, and quickly abandoned. A team at the Centre de Recherche sur la Conservation (CNRS/Muséum National d'Histoire Naturelle/Ministère de la Culture) has now shone a light on this, in collaboration with the SOLEIL synchrotron and the Laboratoire de Physique des Solides (CNRS/Université Paris-Saclay) .

How to break new records in the 200 metres?
How to break new records in the 200 metres?
Usain Bolt's 200m record has not been beaten for ten years and Florence Griffith Joyner's for more than thirty years. And what about if the secret behind beating records was to use mathematics' Thanks to a mathematical model, Amandine Aftalion, CNRS researcher at the Centre d'analyse et de mathématique sociales (CNRS/EHESS), and Emmanuel Trélat, a Sorbonne Université researcher at the Laboratoire Jacques-Louis Lions (CNRS/Sorbonne Université/ Université de Paris) have proved that the geometry of athletic tracks could be optimised to improve records.

"Thermometer" protein regulates blooming
As average temperatures rise every year, it is no longer rare to see plants flower as early as February. Behind this phenomenon is a complex of proteins whose activity is controlled by temperature changes, as has just been demonstrated by researchers from the Cell and Plant Physiology Laboratory (CNRS / CEA / INRAE / Université Grenoble Alpes) and their partners.

Triglycerides control neurons in the reward circuit
Energy-dense food, obesity and compulsive food intake bordering addiction: the scientific literature has been pointing to connections between these for years. Scientists at the CNRS and Université de Paris have just shown for the first time how fatty nutrients act on the brain in the reward circuit. Published in Cell Metabolism on 5 March 2020, these results shed new light on the connection between food and eating disorders.

Wild boars provide archaeologists with clues to early domestication
Until now, archaeozoologists have been unable to reconstruct the earliest stages of domestication: the process of placing wild animals in captivity remained beyond their methodological reach 1 . Using the wild boar as an experimental model, a multidisciplinary team made up of scientists from the CNRS and the French National Museum of Natural History 2 have shown that a life spent in captivity has an identifiable effect on the shape of the calcaneus, a tarsal bone that plays a propulsive role in locomotion.

Alzheimer's: Can an amino acid help to restore memories?
Alzheimer’s: Can an amino acid help to restore memories?
Scientists at the Laboratoire des Maladies Neurodégénératives (CNRS/CEA/Université Paris-Saclay) and the Neurocentre Magendie (INSERM/Université de Bordeaux) have just shown that a metabolic pathway plays a determining role in Alzheimer's disease's memory problems. This work, published on 3 March 2020 in Cell Metabolism, also shows that supplying a specific amino acid as a nutritional supplement in a mouse model of Alzheimer's restores spatial memory affected early.

A Year of Surprising Science From NASA’s InSight Mars Mission
A new comprehension of Mars is emerging based on the first year of NASA's InSight mission.  Results described in a set of six papers published today, five and one in Nature Communications , reveal a living planet that is the scene of earthquakes, dust devils and strange magnetic impulses.

Oceans: particle fragmentation plays a major role in carbon sequestration
Oceans: particle fragmentation plays a major role in carbon sequestration
A French-British team directed by the Laboratoire d'océanographie de Villefranche-sur-Mer (CNRS/Sorbonne Université) has just discovered that a little known process regulates the capacity of oceans to sequester carbon dioxide (CO2). It should be noted that photosynthesis performed by phytoplankton on the ocean's surface transforms atmospheric CO2 into organic particles, some of which later sink to its depths.

PTSD and resilience after trauma: the role of memory suppression
The terrorist attacks committed in Paris and Saint-Denis (France) on November 13, 2015 have left lasting marks, not only on the survivors and their loved ones, but also on French society as a whole. A vast transdisciplinary research program, the " 13-Novembre " project is codirected by Francis Eustache, neuropsychologist and director of the Inserm Neuropsychology and Imaging of Human Memory laboratory (Inserm/Université de Caen Normandie/École pratique des hautes études/Caen university hospital/Cyceron imaging platform) and Denis Peschanski, historian and CNRS senior scientist.

Unusual DNA structures involved in neuron ageing
Unusual DNA structures involved in neuron ageing
DNA can transiently adopt structures that are more complex than the double helix. Quadruple helices, or DNA quadruplexes, are an example of this. They are the preferred targets in the treatment of cancers. By studying their roles in neurons, an international collaboration involving a chemist from CNRS  1 has for the first time shown that quadruplexes are markers of neuronal ageing and exert a negative influence of autophagy 2 , a primordial process for neurons because of its protective effect against neurodegenerative diseases.

How widespread is illegal fishing’ Albatrosses are helping us with the answer
Using albatrosses fitted with loggers, researchers at the CNRS and La Rochelle Université, in association with the Administration des Terres Australes et Antarctiques Françaises, which manages the natural reserves of the French southern and Antarctic lands, have made a first estimation of the number of non-declared fishing boats operating without an identification system in the Southern Ocean: more than a third of the boats the birds detected in international water were non-declared.

Pattern Formation in Low-Pressure Radio-Frequency Plasmas due to a Transport Instability
Publication by Laboratoire de Physique in Physical Review Letters on December 23, 2019. Pattern formation, observed experimentally in a radio-frequency plasma in annular geometry, and characterized by azimuthal symmetry breaking of the plasma parameters, is reported. The azimuthal modulation increases with increasing pressure in the range 1-300 Pa.

White lupin: the genome of this legume has finally been sequenced
White lupin is a particularly abstemious crop, requiring very little fertiliser and producing high-protein seeds of great nutritive quality. The plant has just yielded the secrets of its genome thanks to the collaboration of eleven French and foreign laboratories coordinated by Benjamin Péret, a CNRS researcher at the Biochimie et physiologie moléculaire des plantes laboratory (CNRS/Inrae/Université de Montpellier/Montpellier SupAgro).

The colours of the Pachacamac idol, an Inca God, finally revealed
Researchers from the CNRS, Sorbonne Université, université Paris 1 Panthéon-Sorbonne, the Muséum National d'Histoire Naturelle and the Musée du Quai Branly - Jacques Chirac have shown colours formerly painted on the Pachacamac idol, a 15th century Inca God and oracle. Paired with the first carbon 14 dating of the object, these results published in PLOS ONE on 15 January 2020 shed light on colour practices, and how important they were in the Andes at that time.

Mars: water could disappear faster than expected
Mars: water could disappear faster than expected
The small red planet is losing water more quickly than what theory as well as past observations would suggest. The gradual disappearance of water (H2O) occurs in the upper atmosphere of Mars: sunlight and chemistry disassociate water molecules into hydrogen and oxygen atoms that the weak gravity of Mars cannot prevent from escaping into space.

From as young as 4, children see males as more powerful than females
As early as 4 years old, children associate power and masculinity, even in countries considered to be more egalitarian like Norway. This is what scientists at the Institut des Sciences Cognitives Marc Jeannerod (CNRS/Université Claude Bernard Lyon 1) report, in collaboration with the Universities of Oslo (Norway), Lausanne and Neuchâtel (Switzerland), in a study published on 7 January 2020 in Sex Roles .

Revealing the structure of axons
Revealing the structure of axons
Axons, the threadlike part of a nerve cell that conducts impulses, are both flexible and strong, which makes them a mystery in the eyes of biologists. Recent studies have shown that under the axonal membrane, rings composed of actin filaments give the structure its flexibility. But those studies had not been able to define the precise architecture of these rings.
