Rediscovered historical aerial photographs of East Antarctica offer the earliest insight into ice evolution in Antarctica, revealing that glaciers along nearly 2000 km of coastline have remained stable or have slightly grown over the last 85 years. The results have just been published in the journal Nature Communications and are the result of a collaboration between researchers from the University of Copenhagen, The Norwegian Polar Institute, The Arctic University of Norway, and the (...)

At the beginning of April, the European Research Council (ERC) announced the results of the "ERC Advanced Grant 2023" call for established researchers. INSU is the host institution for 4 grants, including 1 to ISTerre awarded to Eric Larose for his project CRACK THE ROCK. Congratulations ! In 2024, the ERC will be funding 255 researchers with "Advanced" fellowships, worth a total of 652 million euros, as part of the Horizon Europe program. These grants enable scientists, recognized in (...)

The Amazon is the world’s largest rainforest and river system, vital to the planet’s climate stability and home to irreplaceable biodiversity. It provides critical ecosystem services to the entire globe and the eight sovereign countries and one overseas territory that directly encompass it. The Amazon is home to 47 million people, including more than two million Indigenous people, with their own cultural identities, territorial management practices, and 300 languages. Yet, the Amazon is (...)

The Earth’s polar regions continue to be a hotbed of unexpected atmospheric chemistry phenomena. Although these regions are far away from sources of anthropogenic pollution, these substances can accumulate in the snow and ice. In addition, there are phenomena such as the complete, yet widespread depletion of ground-level ozone occurring only there has intrigued scientists for decades. Now, an innovative manuscript, "Electrical charging of snow and ice in polar regions and the potential (...)

Astronomers have, for the first time, made a direct measurement of the mass of a distant black hole, one so far away that light from its surroundings took 11 billion years to reach us. The team, led by Taro Shimizu at the Max Planck Institute for Extraterrestrial Physics in Germany, involving scientists from the Institute of Planetology and Astrophysics of Grenoble (IPAG - OSUG), found the black hole, called J0920, to have a mass of about 320 million times that of the Sun. This achievement, (...)

How Earth and the Solar System were formed, is an age-old question of humankind. By studying the present state of our planet, scientists were able to trace back our planetary history to the very beginning. Now we know that Earth formed from the dust which encircled the newborn Sun 4.5 billion years ago. An alternative approach to study the origin of our globe is to observe planetary systems currently in the making around distant young stars. An international team of astronomers observed such a system, a young star called HD 144432, surrounded by a dusty planet-forming disk at a distance of 500 light years. The researchers utilized the unique instrumentation suite of the Very Large Telescope Interferometer (VLTI) at the European Southern Observatory’s (ESO) Paranal Observatory in Chile.

In the spring, Alpine glaciers sometimes don a sheer red or orangish veil. Known as ‘red snow’ or ‘blood snow’, this phenomenon is caused by the blooming of Sanguina nivaloides, a microscopic alga. Scientists from the CNRS, the French Alternative Energies and Atomic Energy Commission (CEA), Météo-France, INRAE, and Université Grenoble Alpes turned their attention to this organism, which forms the pillar of a snowy ecosystem still poorly understood. Through their investigation , whose findings have (...)

A new study from Université Grenoble Alpes (UGA), Swansea University (UK) and Ghent University (Belgium) provides large-scale evidence that past dispersal success across major barriers was not random, but linked to species characteristics.
The movement of animals across major barriers, such as oceans or mountain ranges, has long intrigued scientists for its role in shaping Earth’s biodiversity. This new study has unveiled groundbreaking insights into this process, showing how (...)

Ranked in the top 150 in the global ranking published last August, Université Grenoble Alpes maintains its position in the Shanghai 2023 ranking with a strong performance in the thematic ranking published on 27 October. For 13 disciplines, the university is in the top 100 of the world’s best universities, including 5 in the top 50 and 2 in the top 20. It is therefore the 4th French university in terms of the number of disciplines ranked in the top 100. This new ranking confirms UGA’s position as the country’s leading research-intensive university, after the universities of Ile-de-France.
It ranks 8th among the world’s top universities in remote sensing (1st in France) and 18th (3rd in France) in Earth Sciences, two themes covered by the OSUG laboratories.
