The Best of Journalism: On Science and Technology News #13 | engineering techniques

Every month, we survey the French and international press to offer you a selection of the most important, amusing, surprising or most useful scientific and technological information!

Here, you’ll find our summary of the science and technology news that shook or turned June on its head. And as tradition dictates: at the end of this article, additional information!

Metal-eating plants

Mentioned in Top Publications #12, Claude Grayson is the winner of the European Inventor Prize 2022 in the ‘Research’ category, which was awarded at a ceremony on June 21. The Director of Research at the National Center for Scientific Research, who issued twelve patents, is rewarded for the methods of using the plants she has developed. This solution makes it possible to extract mineral elements from contaminated soil, such as mining soil, and then exploit these minerals. These “environmental catalysts” are used to create new molecules for industry. “Our processes make it possible, thanks to them, to produce useful and complex molecules that would otherwise be synthesized.”rejoice.

Flying lab dedicated to air analysis

Ile-de-France residents may have noticed the unusual low-altitude flight of an aircraft, the task of which is to take air measurements. From June 14 through July 7, the ATR42 of the French Aircraft Service Prepared for Environmental Research (SAFIRE), operates from Pontoise airport for three hours a day, according to the National Center for Scientific Research (CNRS). It takes measurements mainly over the forests of Ile-de-France, but not only.
Many public research laboratories have equipped this real flying laboratory with multiple sensors and analysis systems. The goal is to better understand the transformations that urban pollution undergoes (such as that from exhaust gases) when it combines with the products naturally emitted by plants in semi-rural and forested areas.

The VivaTechnology Fair took place from June 15-18. In search of innovations, we found the Grenoble-based company ROSI. It recycles solar modules from end-of-life photovoltaic panels. Its CTO, Guy Chichenod, spoke with Science and the future: “Our process makes it possible to recover extremely pure silicon from cells as well as silver from wires used to collect the current produced by each cell, which was not possible before.. Our innovation is that these materials can be reused virtually limitlessly and reduce the carbon footprint of the PV industry by 90%.”.
Among Numeraman’s favorite innovations are La Grangette’s connected vegetable garden, Cosmo Connected augmented reality glasses and La patisserie numérique’s 3D food printing solution.

Amazon drone delivery tests

The e-commerce giant has chosen Lockerford, California to begin delivering drones. With this service, dubbed Prime Air, consumers will be able to choose Among the thousands of daily products Which drone will drop in their garden, we learned from an Amazon press release dated June 13. This experience should allow the service to improve, in order to spread it widely.
Several prototypes were needed, before arriving at a model capable of identifying and avoiding fixed and moving obstacles, such as chimneys, other atmospheric devices, and pets. Prime Air’s drones will be able to carry 2.3 kg of products in a package, at a range of 24 kilometers, according to a spokesperson for the group. ” Later this year (…) Residents will be able to register to be delivered by drone for free ‘, refers to the press release, without specifying a date.

picture of our galaxy

On Monday, June 13, the Gaia Space Telescope presented its new data on nearly two billion stars in the Milky Way. The accuracy of this third harvest of data makes it possible to map our galaxy, which appears to be full of life.
This science mission, the European Space Agency (ESA) mission, was launched in 2013. While presenting the data collected by Gaia, Josef Asbacher, Director General, was delighted: “(c)t is a great day for astronomy, as it opens the door wide for new discoveries about the universe and our galaxy. »

The Space Observatory, located 1.5 million kilometers from Earth, opposite the Sun, is mapping our galaxy in all its dimensions, using two telescopes and a billion-pixel photographic sensor. This helps to understand its origin, structure and dynamics.
700 million data sent to Earth daily, for a period of 34 months, revealed unexpected information. For example, 220 million light spectrums will make it possible to estimate the mass, color, temperature and age of stars for the first time. Gaia has also recorded stellar “quakes,” which are 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, gently swirling around it, like a liquid gently stirred with a wooden spoon. But not at all! François Menard, Scientific Director of the Gaia Expedition to France. Develops her. On the contrary, the life of a batachon is made of accidents and unexpected movements and it is not so simple From this vortex that you describe. For example, our solar system It not only rotates in a vertical plane, it goes up and down, up and down ‘, he says again.

Eve Coppins passed away at the age of 87 on June 22. He directed the National Museum of Natural History, and served as Chair of Paleontology and Prehistory at the Collège de France. He will remain above all associated with Lucy, the young Australopithecus who discovered his crater in 1974 with other scientists.
Greetings from the world abound on the Internet, and many content is available again: His search for man, ” How did we become human?His passion for “ancient stones” earned him the nickname “Coco Fossil”.

Music Bonus: Records and Music Streaming Algorithms

This June’s bounty is an echo of the Fête de la Musique, which celebrated its 40th anniversary on June 21. CNRS magazine published the music file on this occasion. Our attention is drawn to the impact of algorithms on listening to music, across multiple streaming platforms. ” What does the big data collected by the platforms say about our listening behavior and tastes? » is one of the problems addressed by RECORDS (1), a” Collaborative research conducted by researchers and engineers working in three CNRS laboratories and R&D departments at Deezer and Orange. »
Deezer provided this team of researchers with an anonymous listening history of its users. ” The work of the logs reflects the usual perspective on the role of algorithms in the formation of filter bubblesexplains Camille Roth, National Center for Scientific Research Research at the Crossroads of Social Sciences, Mathematics and Computer Science at the Mark Bloch Center. Instead of looking at whether behavior deviates from the recommendation, we study how users approach the recommendation. We then realize that there are different situations and that the effect of recommendation and liquidation varies according to these situations. On the issue of filter bubbles on the Internet, we really have to make the effort to distinguish between different categories of users. »
“Our analyzes lead us to rule out theories whereby an automated recommendation would systematically separate the choices of Internet users, or on the contrary would ensure exposure to a wider range of content, including less popular ones.”concludes Thomas Lowell, National Center for Scientific Research researcher and coordinator of the RECORDS project.
