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.

Quantum devices revolutionise infrared detection
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 .

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.

A Universe Aglow
MUSE spectrograph reveals that nearly the entire sky in the early Universe is glowing with Lyman-alpha emission Deep observations made with the MUSE spectrograph on ESO's Very Large Telescope have uncovered vast cosmic reservoirs of atomic hydrogen surrounding distant galaxies. The exquisite sensitivity of MUSE allowed for direct observations of dim clouds of hydrogen glowing with Lyman-alpha emission in the early Universe - revealing that almost the whole night sky is invisibly aglow.

Collective electron excitations break down quantum Hall effect in graphene
The quantum Hall effect (QHE) is one of the most important effects being studied by solid-state physicists today. Measuring the limits at which it breaks down is extremely important - not only for fundamental physics but also for applying the effect as a resistance standard for redefining the kilogram.

Gravitational waves shed first light on mergers of neutron stars
This is a major breakthrough in more than one respect. The scientists of the LIGO-Virgo Collaboration (which includes the CNRS) have for the first time observed the gravitational waves emitted by the merger of two neutron stars, rather than of two black holes as in previous cases. In another first, the light emitted from the source of gravitational waves was observed in the following hours, days and weeks, by 70 other groundand space-based observatories.

When a porous solid retains its properties in liquid form
Known for their exceptional porosity that enables the trapping or transport of molecules, metal-organic frameworks (MOFs) take the form of a powder, which makes them difficult to format.

Highest-energy cosmic rays have extragalactic origin
Highest-energy cosmic rays have extragalactic origin
A 50-year-old debate has at last been settled: the highest-energy cosmic rays do not originate in our own Galaxy but in galaxies located tens or even hundreds of millions of light years away.
