How is an ionic liquid structured when it comes into contact with a wall?
Publication of the Physics Laboratory and Chemistry Laboratory in the journal Langmuir on November 16, 2023. News by CNRS Chemistry on December 19, 2023. Water flowing over soluble rocks can create patterns of multiple troughs bordered by sharp ridges. By combining field measurements, a numerical model and laboratory experiments, a team led by the MSC laboratory (CNRS/Université Paris Cité), in collaboration with the LPG (CNRS/Nantes Université/Université d'Angers) and the RDP (CNRS/ENS de Lyon/Inrae) has shown that the appearance of these shapes results from a geometric mechanism.

Stellar winds regulate growth of galaxies
Stellar winds regulate growth of galaxies
Galactic winds enable the exchange of matter between galaxies and their surroundings. In this way, they limit the growth of galaxies, that is, their star formation rate. Although this had already been observed in the local universe, an international research team led by a CNRS scientist 1   has just revealed-using MUSE, 2  an instrument integrated into the European Southern Observatory's (ESO) Very Large Telescope-the existence of the phenomenon in galaxies which are more than 7 billion years old and actively forming stars, the category to which most galaxies belong.

A new, more abundant catalyst to generate dihydrogen from water
Publication of the Chemistry Laboratory in the journal ACS Catalysis on November 9, 2023. Communication of CNRS Chemistry on November 27, 2023. Producing dihydrogen by electrolysis of water requires rare and therefore expensive catalysts. They could be replaced by another molybdenum-based catalyst, much more abundant but currently less efficient.

Pulsar emits highest-energy radiation ever observed
Pulsar emits highest-energy radiation ever observed
Pulsars, small, very dense dead stars, emit electromagnetic radiation in the form of beams that sweep through space at regular intervals, rather like cosmic lighthouses. Now, recent observations of one of the nearest pulsars to Earth, the Vela pulsar, have caused a major stir in the scientific community: radiation around 200 times more energetic than any previously detected from this source has been detected at the H.E.S.S.

VeriQuB: a European project for ensuring the reliability of quantum systems
How can we guarantee the reliability of quantum systems? This is the challenge being addressed by an ambitious European research project called VeriQuB, coordinated by the QAT team (Inria, École normale supérieure - PSL, CNRS) at the Inria Paris centre. Its aim is to identify new methods for verifying the performance of quantum computers using bosons.

Phase separation at the heart of the cell nucleus
Publication of the LBMC  in the journal PNAS on August 7, 2023. Communication of CNRS-INSB on September 8, 2023. The organization of heterochromatin, the part of the genome containing repressed genes, into three-dimensional compartments is essential for the correct functioning of cells. But the mechanisms governing this organization are still not fully understood.

How do you fit a bale of straw into the eye of a needle?
Publication of the Physics Laboratory in the journal PNAS, on July 18, 2022, and Nano Letters, on May 22, 2023. Communication of CNRS-INP on July 17, 2023. Researchers at the Physics laboratory of ENS de Lyon (CNRS/ENS de Lyon) have recreated artificial pores that mimic the functioning of two types of biological pore, paving the way for the manufacture of selective nano-pumps and nano-filters.

Disoriented order
Publication of the Physics Laboratory in the journal Nature on June 14, 2023. Communication of the CNRS-INP on June 14, 2023. A research team involving members of the Physics Laboratory of ENS de Lyon has demonstrated the existence of a new form of order never before identified in nature: 'non-orientable' order, which can endow simple structures with properties that enable them to store information.

Superionic ammonia created and analyzed in the laboratory
Superionic ammonia created and analyzed in the laboratory
Ammonia plays an important role in the mechanisms at work inside the planets Uranus and Neptune. Experiments carried out at the Laboratory for the Use of Intense Lasers (LULI) have reproduced the extreme conditions prevailing on these planets, and demonstrated the fusion of "superionic" ammonia ice. These results are reported in the journal Nature Physics.

A French-German laboratory for identifying the nature of dark matter
A French-German laboratory for identifying the nature of dark matter
  Dark matter remains a scientific mystery: it makes up 26% of our Universe's total energy density, but has never been observed. The CNRS and German research centres from the Helmholtz Association have joined forces to create the Dark Matter Lab (DMLab), an International Research Laboratory (IRL) focusing on the mysterious substance that is dark matter.

James Webb Space Telescope reveals composition of protoplanetary disc
  Young stars are surrounded by discs of material from which future planets form. The James Webb Space Telescope has revealed the chemical composition of the disc around the star J160532, which turns out to be rich in hydrocarbons. In recent years, observations  have shown that rocky exoplanets are very abundant around low-mass stars such as J160532.

Parking problems seen from the standpoint of physics
Parking problems seen from the standpoint of physics
In major metropolises, drivers looking for parking often represent more than 10% of urban traffic 1 , making both pollution and frustration worse! Can physics help understand the headache of parking in cities? Yes, if we are to believe the research conducted by a team led by a CNRS researcher at the Institute of Light and Matter (CNRS/Université Claude Bernard Lyon 1), which has proposed a new approach to the topic.
