New Juno results suggest that the violent thunderstorms taking place in Jupiter's atmosphere may form ammonia-rich hail, or 'mushballs', that play a key role in the planet's atmospheric dynamics. This theory, developed using data from Juno's microwave radiometer by the Juno team, is described in two publications led by a researcher at the Laboratoire Lagrange (CNRS/Observatoire de la Côte d'Azur/Université Côte d'Azur) with support from the CNES.

Iron-mediated cancer cell activity: a new regulation mechanism
Researchers at the Institut Curie have recently shown that cancer cells use a membrane protein that has been known for several decades to internalise iron. Published (August 3rd, 2020), this work shows that the absorbed iron allows cancer cells to acquire metastatic properties. Biologists knew CD44 well, but didn't know the major biological function that it fulfils.

How flies flip around on take-off from an upside- down position
Flies are able to right themselves very quickly when taking off from an upside-down position. Scientists from the CNRS and from The Institute of Movement Science (ISM) at Aix-Marseille Université studying this phenomenon discovered the surprising way these insects begin by turning their bodies before their heads on take-off.

Behind the dead-water phenomenon
Behind the dead-water phenomenon
What makes ships mysteriously slow down or even stop as they travel, even though their engines are working properly? This was first observed in 1893 and was described experimentally in 1904 without all the secrets of this "dead water" being understood. An interdisciplinary team from the CNRS and the University of Poitiers has explained this phenomenon for the first time: the speed changes in ships trapped in dead water are due to waves that act like an undulating conveyor belt on which the boats move back and forth.

Unprecedented ground-based discovery of two strongly interacting exoplanets
Unprecedented ground-based discovery of two strongly interacting exoplanets
Several interacting exoplanets have already been spotted by satellites. But a new breakthrough has been achieved with, for the first time, the detection directly from the ground of an extrasolar system of this type.  An international collaboration including CNRS researchers 1 has discovered an unusual planetary system, dubbed WASP-148, using the French instrument SOPHIE at the Observatoire de Haute-Provence (CNRS/Aix-Marseille Université) .

Quasar jets are particle accelerators thousands of light-years long
An international collaboration bringing together over 200 scientists from 13 countries has shown that the very high-energy gamma-ray emission from quasars, galaxies with a highly energetic nucleus, is not concentrated in the region close to their central black hole but in fact extends over several thousand light-years along jets of plasma.

Matrix imaging: an innovation for improving ultrasound resolution
Matrix imaging: an innovation for improving ultrasound resolution
In conventional ultrasounds, variations in soft tissue structure distort ultrasound wavefronts. They blur the image and can hence prove detrimental to medical diagnosis. Researchers at the Institut Langevin (CNRS/ESPCI Paris-PSL) 1 have developed a new non-invasive ultrasound method that avoids such aberrations.

Tuberculosis: discovery of an ancestral lineage in the African Great Lakes region
Two exceptional strains of tuberculosis, isolated from East African patients with multi-resistant forms of the disease, have been discovered thanks to the use of a new molecular test, Deeplex-MycTB 1. These strains belong to a so far unknown bacterial lineage, apparently limited to the African Great Lakes region.

Discovering the prehistoric monuments of Arabia
In contrast to the prehistoric remains of the Near East, the megalithic monuments of Arabia remain largely unknown. These monumental structures, made of dry stone walls, still hold many secrets in terms of their construction, function and chronology. An international collaboration 1 of scientists from France, Saudi Arabia and Italy 2 , led by Olivia Munoz, a researcher at the CNRS, have discovered a 35-metre long triangular platform in the oasis of Dûmat al-Jandal (northern Saudi Arabia).

Cell reproduction dogma challenged
Cell reproduction dogma challenged
Meiosis is essential to sexual reproduction. For almost 15 years, it has been commonly held that retinoic acid, a molecule derived from vitamin A, triggers meiosis in mammalian germ cells. Yet, in joint articles published in Science Advances ( 22 May 2020 ), researchers from the Institut de Biologie Valrose (CNRS / INSERM / Université Côte d'Azur) and the IGBMC (CNRS / INSERM / University of Strasbourg), with their colleagues, demonstrate that meiosis in mice begins and proceeds normally even in the absence of retinoic acid.

Mars: where mud flows like lava
Mars: where mud flows like lava
The surface of the planet Mars bears probable traces of -sedimentary volcanism-, a geological phenomenon that leads to the eruption of mud from underground. But how does a mixture of sediment and water behave in the open air on the Red Planet? Conditions there are extremely different from those on Earth - atmospheric pressure is 150 times lower and temperatures are generally negative.

A century of misunderstanding of a key tool in the economics of natural resources
In the past few weeks, oil prices have fallen to record lows. This development was not predicted by the Hotelling rule, an equation proposed in 1931 that remains central to the economics of natural resources today. In an article published on 11 May 2020 in the Canadian Journal of Economics , economists Roberto Ferreira da Cunha, of the Berkeley Research Group, and Antoine Missemer, of the CNRS, present the results of a groundbreaking historical survey of documents from Harold Hotelling's archives.

Scientists observe bacteria tumble their way out of surface traps
While tracing the movement of Escherichia coli, a team of French researchers noticed that near solid surfaces, the bacteria run in circles. Loop after loop, the tracing almost looks like an Olympic figure skating rink before the Zamboni irons the sheet of ice smooth. Breaking down E. coli's routine step by step, the scientists identified a signature move-surface tumbling.
