The fifth episode of the ExpeLab series focuses on the new analytical platform IMAP of the Institute of Earth Sciences (ISTerre - CNRS/IRD/UGA/UGE/USMB) which makes minerals talk about the origins of the Earth.
Selenium is a micronutrient that plays an essential role in human health but is toxic at high levels. However, new biomedical research has shown selenium actually has anti-cancer properties when used at high doses. To overcome problems with its inherent toxicity, an international research team, led by Professor Steve Conlan in Swansea University and Professor Laurent Charlet (ISTerre / OSUG) at Université Grenoble Alpes, tested whether selenium nanoparticles could be developed as a potential (...)
On Tuesday, March 21, 2023 at 6:30 pm, the doctoral candidates from the Grenoble academic final of MT180 will be on stage at the MC2: Grenoble auditorium for the 10th edition of the international competition "Ma thèse en 180 secondes". A scientific and fun evening, free of charge, open to all upon registration.
To make the greatest number of people understand their thesis topics, in three minutes, with a single slide, this is the challenge that the finalists MT180 PhD students take up. For (...)
The results are in: the Shanghai 2022 ranking once again places Grenoble Alpes University among the top 150 universities in the world. It is listed in the top 100 of the world’s best universities in 15 disciplines, including six in the top 50 and one in the top 20.
Among these disciplines are the Earth sciences with no less than 500 universities evaluated. In this thematic ranking, UGA is ranked 24th in the world, and 3rd nationally after the Sorbonne University and the University of (...)
While volcanic eruptions and earthquakes serve as immediate reminders that Earth’s insides are anything but tranquil, there are also other, more elusive, dynamic processes happening deep down below our feet. Using information from ESA’s Swarm satellite mission, scientists have discovered a completely new type of magnetic wave that sweeps across the outermost part of Earth’s outer core every seven years. This fascinating finding, presented today at ESA’s Living Planet Symposium, opens a new (...)
Mercury being so close to the Sun, the environment of formation of the planet is considered to be depleted in oxygen, and thus very reducing, leading to the presence of significant quantities of silicon alloyed with iron in its core (Fe-Si alloy). However, the phase diagram of the Fe-FeSi system remained poorly constrained to the high pressure and high temperature conditions prevailing at the center of Mercury
A team of researchers, led mainly by members of IMPMC and ISTerre, have (...)
Metropolitan France shows a strong structural heritage and a low deformation rate. However, destructive earthquakes can occur there. Active faults are therefore a priority research topic for our societies. In this article and as part of a national effort to identify the still largely fragmentary knowledge, the team of researchers involved in this study stresses that major efforts from the active tectonics and paleoseismology community are needed to generate robust data, especially on the (...)
Published on November 24, 2021 Academy of Sciences
On 23 November, took place under the dome of the Institut de France, the Award ceremony of the Academy of Sciences 2021. These awards honour experienced scientists or young researchers at the beginning of their careers. Through them, the Academy of Sciences contributes directly to its mission of encouraging scientific life.
Among these awards, the Prix Ampère de l’Électricité de France 2021 was awarded to the Géodynamo team of ISTerre. This award recognises one or more researchers working in a (...)
New research by scientists from the VIB-VUB Center for Structural Biology (Belgium), the Radboud University (Netherlands), Institut de Biologie Structurale and The Institut des sciences de la Terre de Grenoble, ISTerre/OSUG (CNRS/IRD/Université Grenoble Alpes/Université Savoie Mont Blanc) (Grenoble) using cryo-electron microscopy now demonstrates that these protein crystal nuclei don’t have to work in isolation: the presence of nearby nuclei can help early-stage protein crystals find their ’shape’.
