Each month, we analyze the French and international press to offer you a selection of the most essential, fun, surprising or very useful scientific and technological information!
Here is our summary of the scientific and technological news that shook or turned upside down in June. And, as tradition dictates, at the end of this article, additional information!
plants that eat metals
She was mentioned in the best press number 12, Claude Grison is the winner of the 2022 European Inventor Award in the “Research” category, presented at a ceremony on June 21. The CNRS research director, responsible for twelve patents, is awarded for the methods of use of plants he has developed. The solution allows to extract metallic elements from contaminated soils, such as mining soils, and then exploit these metals. These “eco-catalysts” are used to create new molecules for industry. “Our processes allow us to produce, thanks to them, useful and very complex molecules to synthesize in another way”he rejoices.
A flight laboratory dedicated to air analysis
Ile-de-France residents may have noticed the unusual low-altitude overflight of a aircraft, whose mission is to perform measurements from the air. From June 14 to July 7, the ATR42 from French Instrumented Aircraft Service for Environmental Research (SAFIRE)operates from Pontoise Airport, three hours a day, specifies the National Center for Scientific Research (CNRS). It takes action mainly above the forests of the Île-de-France, but not only.
Several public research laboratories have equipped this true flight laboratory with multiple sensors and analysis systems. The aim is to better understand the transformations that urban pollution undergoes (such as that due to exhaust fumes) when combined with products emitted naturally by plants in semi-rural areas and forests.
The VivaTechnology fair was held from 15 to 18 June. In search of innovations, we found the Grenoble company ROSI. Recycle solar modules from photovoltaic panels at the end of their useful life. He spoke with its chief technology officer, Guy Chichignoud Science and future: ” Our process allows us to recover the ultra-pure silicon from the cells as well as the silver from the cables used to collect the current produced by each cell, which was not possible before.. Our innovation lies in the possibility of reusing these materials almost indefinitely and reducing the carbon footprint of the photovoltaic industry by 90% ”..
And among Numeraman’s favorite innovationsthey include La Grangette’s Connected Orchard, Cosmo Connected’s Augmented Reality Glasses, and La Pastisseria Numérique’s 3D Food Printing Solution.
Amazon drone delivery tests
The e-commerce giant has chosen the city of Lockerford, California, to get started on drone delivery. With this service, call Prime Air, consumers will be able to choose ” among thousands of everyday products who will be dropped by the drone in his garden, we learned of Amazon’s June 13 press release. This experience should improve the service, in order to deploy it on a large scale.
Lots of prototypes were needed, before the capable model could be reached identify and avoid obstacles, static and moving, such as chimneys, other aerial devices, and pets. Prime Air drones will be able to transport 2.3 kg of products in a package, in a distance of 24 km, according to a spokesman for the group. ” After this year (…) residents will be able to register to be delivered by drone for free “, Indicates the press release, without specifying a date.
A portrait of our galaxy
Monday, June 13, the The Gaia space telescope has presented its new data more than two billion stars in the Milky Way. The accuracy of this third data collection is such that it allows us to map our galaxy, which seems to be boiling with life.
This scientific mission, important for the European Space Agency (ESA), was launched in 2013. During the presentation of the data collected by Gaia, Josef Aschbacher, general manager, was delighted: “cIt is a fantastic day for astronomy, which opens the floodgates to new discoveries about the Universe and our galaxy. »
SLocated 1.5 million kilometers from Earth, facing the Sun, the space observatory maps our galaxy in all its dimensions, using two telescopes and a billion-pixel photographic sensor. This helps to understand its origin, structure and dynamics.
The 700 million data sent to the ground every day for 34 months revealed unexpected information. For example, the 220 million photometric spectra will be used to estimate the mass, color, temperature, and age of stars for the first time. Gaia has also recorded stellar “tremors”, small movements on the surface of a star that change its shape.
Our galaxy is more turbulent than expected. ” It was thought to have reached a steady state, swirling gently around, like a liquid gently stirred with a wooden spoon. But not at all! “, develops François Mignard, scientific director of the Gaia mission for France. She” the life of the patachon is made up of accidents, unexpected and not so simple movements that this spiral she describes. For example, our solar system not only does it rotate in a perpendicular plane, but it goes up and down, above and below “He said.
Yves Coppens died on June 22 at the age of 87. He directed the National Museum of Natural History, and held the chair of paleontology and prehistory at the College de France. He will remain mostly related to Lucy, a young Australopithecus whose fossil he discovered in 1974 with other scientists.
Tributes to the scientist abound on the net, many contents are again available: his human research” How did we become human?“his passion for” old stones “that earned him the nickname” I cook the fossil“.
Music bonus: RECORDS and music playback algorithms
This June’s bonus echoes the Fête de la Musique, which celebrated its 40th anniversary on 21 June. On this occasion, the CNRS magazine published a dossier on music. It catches our eye the impact of algorithms on listening to music, across multiple streaming platforms. ” What do the big data collected by the platforms say about our listening behavior and our tastes? » is one of the issues addressed by RECORDS (1), a ” collaborative research conducted by researchers and engineers working in three laboratories of the CNRS and the R&D departments of Deezer and Orange. »
Deezer provided this team of researchers with anonymous listening stories from its users. ” The work of Records reverses the usual perspective on the role of algorithms in the formation of filter bubblesexplains Camille Roth, a CNRS researcher at the crossroads of the social sciences, mathematics and computer science at the Marc Bloch Center. Instead of looking at whether the behavior deviates from the recommendation, let’s look at how users handle the recommendation. We then realize that there are different attitudes and that the impact of recommendation and filtering varies according to these. On the issue of Internet filter bubbles, we really need to make an effort to distinguish between different classes of users.. »
“Our analysis leads us to rule out theories that automated recommendation would systematically compartmentalize the options of Internet users, or instead guarantee exposure to a greater variety of content, including less popular ones.”concludes Thomas Louail, CNRS researcher and coordinator of the RECORDS project.
