Multiple myeloma is a cancer of the bone marrow, with a life expectancy of less than 5 years post-diagnosis. Proteasome inhibitors, the therapeutic backbone of current treatments, are very effective in treating newly diagnosed cancers but resistance or intolerance to these molecules inevitably develop, leading to relapses. While studying a neglected tropical disease , Buruli ulcer, researchers from the Institut Pasteur and Inserm discovered a novel therapeutic target for multiple myeloma that could allow to bypass this resistance. The results of this study were published in

Reducing air pollution: policies that pay off
Reducing air pollution: policies that pay off
Every year in France, fine particle pollution (particles with a diameter of less than 2.5 micrometres 1 ) leads to the premature death of around 40,000 people. The associated cost is estimated at €100 billion per year. Despite this, public policies to combat air pollution are generally implemented without first assessing their future health and economic impacts.

Neufeld from University of Cambridge 2 , propose a new model of crystallization of the lunar magma ocean where the crystals remain suspended in the lunar interior and the formation of the crust only begins once a critical crystal content is reached.

Discovery of the least 'metallic' stellar structure in the Milky Way
Discovery of the least ’metallic’ stellar structure in the Milky Way
98.5% of the Sun is made up of two light chemical elements, hydrogen and helium, while the remaining 1.5% consists of other heavier elements such as carbon, oxygen, and iron. The abundance of these heavier elements in a star is called its 'metallicity', and varies from star to star. It now turns out that our Galaxy is home to a stellar structure uniquely made of stars with extremely low metallicity, with a heavy element content 2,500 times lower than that of the Sun.

Microplastic discovered in ’pristine’ Pyrenees mountain air
Previously detected in rivers, oceans, and snow, 1 microplastic has now been found in the high-altitude air surrounding the Pic du Midi (2,877 m)-by an international research team including scientists from the CNRS, Université Grenoble Alpes, 2 and the University of Strathclyde (Scotland). After analysing the composition of 10,000 m3 of air captured weekly by a pump installed at the Pic du Midi Observatory, 3 the researchers report a microplastic concentration of approximately one particle per 4 m3.

Invited CEA-Leti Paper at IEDM 2021 Identifies Main Challenges Facing Large-Scale Si Quantum Computing
SAN FRANCISCO - Dec. 16, 2021 - CEA, in collaboration with CNRS Néel, a leading team in SI-based quantum c'omputing, presented two papers on that topic at IEDM 2021, including an invited paper that identifies the material and integration challenges facing large-scale Si quantum computing. The second paper presents a novel Si quantum device integration that reduces by half the effective gate pitch and provides full controllability in 1D FD-SOI quantum dot (QD) arrays.

SAN FRANCISCO 2021 - CEA-Leti has reported the world's-first demonstration of 16-kbit ferroelectric random-access memory (FeRAM) arrays at the 130nm node that advances this energy-saving technology closer to commercialization. The breakthrough includes back-end-of-line (BEOL) integration of TiN /HfO 2 :Si/TiN ferroelectric capacitors as small as 0.16 µm², and solder reflow compatibility for the first time for this type of memory.

Experiment gives rise to social conventions between baboons
Shaking hands is an example of a social convention to say hello or goodbye. For the first time, scientists have studied the development of social conventions in non-human primates. Baboons, for example, can also establish conventions A research team from the CNRS and Aix-Marseille Université has demonstrated that members of a group of baboons can establish shared social conventions - in this case, by all agreeing on how to solve a problem in order to get a reward faster.

Einstein wins in the end (once again)
Einstein's theory of gravity, general relativity, has not been disproven once in over a century, despite relentless efforts from scientists to find its faults. Pulsars are stars toward the end of the stellar life cycle, emitting radio waves that sweep through space like a lighthouse: they can be detected by radio telescopes in the form of highly regular flashes.

Research Team Proposes New Approach for Next-Generation Memories with RRAM Energy-Storage Breakthrough
In-memory energy is a supplemental feature to in-memory computing, which is a key focus in CEA-Leti's roadmap. It can reduce energy use dramatically because RRAM-based batteries are highly scalable and dynamically allocable, and they can be placed next to memory blocks, which are near the processor. Locating the energy supply close to the processor is especially helpful when the processor requires peak power, which typically comes from an external source.

When variations in Earth's orbit drive biological evolution
When variations in Earth’s orbit drive biological evolution
Coccolithophores are microscopic algae that form tiny limestone plates, called coccoliths, around their single cells. The shape and size of coccoliths varies according to the species. After their death, coccolithophores sink to the bottom of the ocean and their coccoliths accumulate in sediments, which faithfully record the detailed evolution of these organisms over geological time.

Chatbot for addressing COVID-19 vaccine hesitancy
A considerable fraction of the population is reluctant to get vaccinated against COVID-19. French scientists have designed a chatbot that offers personalised responses to questions posed by the curious or hesitant-and have demonstrated its effectiveness. What if a few minutes of interaction with a chatbot could effectively address vaccine concerns? In an article published in the Journal of Experimental Psychology: Applied (28 October 2021), researchers from the CNRS, INSERM, and ENS-PSL show that such an interface is indeed capable of swaying the vaccine-hesitant.

New, promising opportunities for treating skin fibrosis
Skin fibrosis impairs skin tissue function, and has a strong aesthetic impact. French researchers have now shown that applying an electric field to the skin could cure skin fibrosis by reducing overly high collagen levels. Collagen, the main component of the skin's extracellular matrix, can cause a pathological condition if it is in excess.

A new therapeutic target to combat addiction?
A new therapeutic target to combat addiction?
Drug addiction is a psychiatric disorder for which no pharmacological treatment with long-term efficacy currently exists. All addictive substances share the property of raising concentrations of the neurotransmitter dopamine within brain regions forming the neural reward circuit. This increase in dopamine levels results in long-lasting alteration of signal transmission that is dependent on another neurotransmitter, glutamate, which causes addictive behaviours.

Mars: first results from the Perseverance rover
Images from Perseverance's French-American instrument SuperCam show that the crater where the rover landed once contained a lake. The SuperCam observations also identified strata containing boulders, related to a major change in the hydrological regime. This study, led by a French researcher, will facilitate selection of the most suitable areas for Perseverance to collect samples.
