Fast fine art : 19th century painting tricks revealed
Fast fine art : 19th century painting tricks revealed
Paris, 9 January 2017 To paint quickly while creating exceptional texture and volume effects, J. M. W. Turner and other English artists of his generation relied on the development of innovative gels. All the rage in the 19th century—and still in use today—these compounds alter the properties of the oil paints they are combined with.

A new method for weighing super-massive black holes
A new method for weighing super-massive black holes
Paris, 29 November 2018 Scientists have revealed, for the first time outside our Galaxy, the properties of rapidly moving gas clouds in the immediate vicinity of a super-massive black hole, enabling the mass of the black hole to be measured with unprecedented accuracy.

Parker Solar Probe : French research takes off for the Sun
Parker Solar Probe : French research takes off for the Sun
Parker Solar Probe will soon become the spacecraft to travel the closest to the Sun, by positioning itself a little over 6 million kilometers from our star's surface. During its journey within the solar corona, the NASA probe will notably have an on-board instrument developed by researchers from the CNRS, université d'Orléans, and the CNES.

GRAVITY confirms predictions of general relativity near the Galactic Centre Massive Black Hole
GRAVITY confirms predictions of general relativity near the Galactic Centre Massive Black Hole
Observations made with the Very Large Telescope (VLT) of the European Southern Observatory (ESO) have, for the first time, detected the effects of general relativity predicted by Einstein, in the movement of a star passing into the intense gravitational field of Sagittarius A * , a massive black hole at the centre of the Milky Way.

Planck : final data from the mission lends strong support to the standard cosmological model
Planck : final data from the mission lends strong support to the standard cosmological model
In 2013, ESA's Planck mission unveiled a new image of the cosmos: an all-sky survey of the microwave radiation produced at the beginning of the Universe. This first light emitted by the Universe provides a wealth of information about its content, its rate of expansion, and the primordial fluctuations in density that were the precursors of the galaxies.

Launch of a joint international laboratory between the CNRS and Hitachi High Technologies Corporation
Launch of a joint international laboratory between the CNRS and Hitachi High Technologies Corporation
French researchers and Japanese engineers have joined forces to develop a new electron microscope that can scan the properties of matter on very small scales of time and space. The Centre d'élaboration de matériaux et d'études structurales (CEMES) of the CNRS and the Hitachi High Technologies Corporation (HHT) will formalize the creation of a joint laboratory on July 2, 2018, the first between the CNRS and a foreign company.

First light for SPIRou, exoplanet hunter
First light for SPIRou, exoplanet hunter
SPIRou, the new planet-hunting spectropolarimeter developed for the Canada-France-Hawaii Telescope (CFHT), has successfully recorded its first starlight. Ten years after it was first designed and following four intensive months of installation at CFHT, this international instrument in which France has played a leading role is on the point of initiating its scientific operations, namely the detection of exoplanets around nearby red dwarf stars and the study of newborn stars and planets.

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.

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.

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.

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 .

Why is it so hot at night in some cities ?
During the nighttime, it is hotter in the city than in nearby suburbs or the countryside. But just how much hotter differs between cities. Researchers from the MSE 2 (CNRS / MIT) international joint research laboratory and the Centre Interdisciplinaire des Nanosciences de Marseille (CNRS / Aix-Marseille University) 1 have shown that the determining factor is how cities are structured: more organized cities, like many in North America with straight and perpendicular streets, trap more heat.
