Part of the Universe's missing matter found thanks to the MUSE instrument
Part of the Universe’s missing matter found thanks to the MUSE instrument
Galaxies exchange matter with their external environment thanks to galactic winds. The MUSE instrument from the Very Large Telescope has, for the very first time, mapped the galactic wind that drive these exchanges between galaxies and nebulae. This observation led to the detection of some of the Universe's missing matter.

Part of the Universe’s missing matter found thanks to the MUSE instrument
CRAL publication in MNRAS , on September 16, 2021. CNRS press release on September 16, 2021. Galaxies can receive and exchange matter with their external environment thanks to the galactic winds created by stellar explosions. Thanks to the MUSE instrument  from the Very Large Telescope at the ESO, an international research team, led on the French side by the CNRS and l'Université Claude Bernard Lyon 1 , has mapped a galactic wind for the first time.

How to Catch a Perfect Wave: Scientists Take a Closer Look Inside the Perfect Fluid
How to Catch a Perfect Wave: Scientists Take a Closer Look Inside the Perfect Fluid
Berkeley Lab research brings us closer to understanding how our universe began S cientists have reported new clues to solving a cosmic conundrum : How the quark-gluon plasma - nature's perfect fluid - evolved into matter. A few millionths of a second after the Big Bang, the early universe took on a strange new state: a subatomic soup called the quark-gluon plasma.

Have we detected dark energy? Cambridge scientists say it's a possibility
Have we detected dark energy? Cambridge scientists say it’s a possibility
Dark energy, the mysterious force that causes the universe to accelerate, may have been responsible for unexpected results from the XENON1T experiment, deep below Italy's Apennine Mountains. It was surprising that this excess could in principle have been caused by dark energy rather than dark matter.

Solar cells with 30-year lifetimes for power-generating windows
Solar cells with 30-year lifetimes for power-generating windows
High-efficiency but fragile molecules for converting light to electricity thrive with a little protection. A new transparency-friendly solar cell design could marry high efficiencies with 30-year estimated lifetimes, research led by the University of Michigan has shown. It may pave the way for windows that also provide solar power.

The mystery of the flexible shell
The mystery of the flexible shell
An international research team with participation of the Paul Scherrer Institute PSI has revealed a secret about a marine animal's shell: The researchers have deciphered why the protective cover of the brachiopod Discinisca tenuis becomes extremely soft in water and gets hard again in the air. The study appears today .

Acoustic illusions
Researchers have devised an ingenious method of using acoustics to conceal and simulate objects. When listening to music, we don't just hear the notes produced by the instruments, we are also immersed in its echoes from our surroundings. Sound waves bounce back off the walls and objects around us, forming a characteristic sound effect - a specific acoustic field.

Unprecedented Plasma Lensing for High-Intensity Lasers
– By Joe Chew High-power laser pulses focused to small spots to reach incredible intensities enable a variety of applications, ranging from scientific research to industry and medicine. At t'he Berkeley Lab Laser Accelerator (BELLA) Center, for instance, intensity is key to building particle accelerators thousands of times shorter than conventional ones that reach the same energy.

An insulator made of two conductors
At researchers have observed a new state of matter: in graphene layers twisted relative to each other, two electrical conductors team up to form an insulator. Ohm's law is well-known from physics class. It states that the resistance of a conductor and the voltage applied to it determine how much current will flow through the conductor.

Surprise: the Milky Way is not homogeneous
Surprise: the Milky Way is not homogeneous
Astronomers from the UNIGE have observed the composition of the gases in our galaxy and have shown that, contrary to the models established until now, they are not homogeneously mixed. In order to better understand the history and evolution of the Milky Way, astronomers are studying the composition of the gases and metals that make up an important part of our galaxy.

Nano ’camera’ made using molecular glue allows real-time monitoring of chemical reactions
Researchers have made a tiny camera, held together with 'molecular glue' that allows them to observe chemical reactions in real time. This platform is a really big toolbox - it opens up lots of new possibilities for imaging chemical reactions Kamil Sokolowski The device, made by a team from the University of Cambridge, combines tiny semiconductor nanocrystals called quantum dots and gold nanoparticles using molecular glue called cucurbituril (CB).

Photovoltaic perovskites can detect neutrons
A simple and cheap device for detecting neutrons has been developed by a team of researchers and their collaborators. The device, based on a special class of crystalline compounds called perovskites, could be used to quickly detect neutrons coming from radioactive materials, e.g. a nuclear reactor that has been damaged or that is being transported nefariously, the researchers say.

Way to check that quantum computers return accurate answers
Way to check that quantum computers return accurate answers
Quantum computers become ever more powerful, but how can we be sure that the answers they return are accurate? A team of physicists from Vienna, Innsbruck, Oxford, and Singapore solves this problem by letting quantum computers check each other. Quantum computers are advancing at a rapid pace and are already starting to push the limits of the world's largest supercomputers.
