Publication from LBMC, IBENS and Isyeb in Science on March 15, 2019. In the Mesorhabditis belari roundworm, the sole purpose of males is to help females produce clones of themselves. This unique form of reproduction was recently described by researchers from the CNRS, l'ENS de Lyon, l'Université Claude Bernard Lyon 1, and the Muséum national d'Histoire naturelle in an article published on 15 March 2019 .

Publication by Laboratoire de chimie, , on August 2019. A new article describes the discovery of a new class of electrolytes, which can improve energy storage efficiency in supercapacitors. A team of scientists from US, France, UK and Australia has worked out a way to improve energy storage devices called supercapacitors, by designing a new class of ionic liquids based on common, non-toxic chemicals.

Cathy Quantin-Nataf, Gilles Dromart and Gilles Montagnac of the Laboratoire de Géologie de Lyon (LGL-TPE) are members of a research team developing one of the instruments that will go aboard the rover of the Mars 2020 Mission: the SuperCam. Watch live as NASA's next rover, Mars 2020, is built and tested in the Spacecraft Assembly Facility at the agency's Jet Propulsion Laboratory in Pasadena, California.

Publication from the IGFL in Current Biology on April 1st, 2019. The genome, which corresponds to the whole DNA content of a cell and is characteristic of an organism, can present big variations in size between species. If this size does not correlate with organismal "complexity", it is not clearly established yet if bigger or smaller genomes could be adaptive.

Over the last few years, scientists have discovered connections between gut microbiota imbalances and various diseases. Now, in a study using mice, biologists from the CNRS, INSERM, and Claude Bernard Lyon 1 University -together with colleagues from the Institut Pasteur de Lille and the NIH (USA)- have revealed a surprising relationship between a viral detection system, the composition of the gut microbiota, and the development of skin allergies.

Abstract: The ovules and seeds of most angiosperm groups are enclosed by two integuments, whose evolutionary origins are considerably separated in time, as the inner integument arose over 300 million years ago (MYA) in an ancestor of all living seed plants, while the outer integument arose, perhaps as recently as 164 MYA, in an ancestor of all living angiosperms.

Publication from the Chemistry laboratory in the Chemical Sciences journal on September 18, 2018. Abstract: The intrinsic photostability of nucleic acids is intimately related to evolution of life, while its understanding at the molecular and electronic levels remains a challenge for modern science.

Abstract: Roses have high cultural and economic importance as ornamental plants and in the perfume industry. We report the rose whole-genome sequencing and assembly and resequencing of major genotypes that contributed to rose domestication. We generated a homozygous genotype from a heterozygous diploid modern rose progenitor, Rosa chinensis 'Old Blush'.

Abstract: ETTIN is an atypical member of the AUXIN RESPONSE FACTOR family of transcription factors, which plays a crucial role in tissue patterning in the Arabidopsis thaliana gynoecium. Though recent insights have provided valuable information on ETT's interactions with other components of auxin signaling, the biophysical mechanisms linking ETT to its ultimate effects on gynoecium morphology were until now unknown.

Marie Bannier, a former normal student in the Biology Department at the ENS de Lyon, participated in the research and writing of this scientific publication as part of her 4th year. During a myocardial infarction, commonly known as a heart attack, the blood supply to part of the heart muscle is cut off.

Through a quirk of nature called "gravitational lensing," a natural lens in space amplified a very distant star's light. Astronomers using Hubble took advantage of this phenomenon to pinpoint the faraway star and set a new distance record for the farthest individual star ever seen. They also used the distant star to test one theory of dark matter, and to probe the make-up of a galaxy cluster.

Fields, streets and cities, but also forests planted in rank and file, and dead straight rivers: humans shape nature to better suit their purposes, and not only since the onset of industrialization. Such influences are well documented in the Amazonian rainforest. On the other hand, the influence of humans was debated in Central Africa where major interventions seem to have occurred there 2,600 years ago: Potsdam geoscientist Yannick Garcin and his team have published a report on their findings in the journal PNAS.

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.

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.

In 2009, the world's largest dinosaur tracks were discovered in the French village of Plagne, in the Jura Mountains. Since then, a series of excavations at the site has uncovered other tracks, sprawling over more than 150 meters. They form the longest sauropod trackway ever to be found. Having compiled and analyzed the collected data, which is published in When sauropod tracks were discovered in the French village of Plagne in 2009 - near Lyon - the news went round the world.

Drosophila testes visualized by confocal microscopy. Necrotic germ cells are visualized in red (white arrowheads), cell nuclei in blue. Victor Girard Cell death allows elimination of supernumerary cells during development or of abnormal cells throughout life. Physiological cell death is tightly regulated to prevent pathologies such as degenerative diseases or cancers, which often occur due to excessive or absent cell death, respectively.

Significance In most biological processes, genes have to be activated and/or repressed. In plants, the TOPLESS protein is essential for gene repression through its action as a corepressor bridging transcription factor with chromatin remodeling complexes. Here we combine biochemical and structural studies to describe the structure of TOPLESS, how it tetramerizes, and how it interacts with its protein partners.
