Since its launch in June 2017, 42 researchers have been selected to join the Make Our Planet Great Again program. Among them, Ignacio Palomo, CNRS researcher hosted at the Alpine Ecology Laboratory (LECA - UMR CNRS-UGA-USMB) and coordinator of the PORTAL project which aims to identify transformative solutions based on nature to face climate change in the Alps. One of the first publications related to the project and to the work of the The Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) appeared this December at the Proceedings of the National Academy of Sciences of the United States of America, and describes the need to tackle climate change and the conservation of biodiversity simultaneously under the framework of the post-2020 biodiversity targets.

It is a story many parents are hoping for: Imagine there’s a very young kid that seems like a real low-performer, but then it turns out that secretly it has its very powerful moments — such that the odds are pre?y good it will become a real star, eventually. In fact, this is very much what an international team of astronomers found when they examined the very young protostar IRAM 04191+1522 (IRAM 04191, in short).

Bacillus thuringiensis subsp. israelensis (Bti) is widely used to reduce mosquito nuisance in Europe and other parts of the world. An evaluation of existing peer-reviewed literature shows that the risk of resistance of mosquitoes to Bti is limited despite spores and toxins persistence in the environment.

An international team of astronomers including researchers from the Grenoble Institute of Planetology and Astrophysics (IPAG / OSUG - CNRS, UGA), has captured fifteen images of the inner rims of planet-forming disks located hundreds of light years away. These disks of dust and gas, similar in shape to a music record, form around young stars. The images shed new light on how planetary systems are formed. The results were published on April 30 in the journal Astronomy & Astrophysics.

Twenty-four years ago, Swiss astronomers Michel Mayor and Didier Queloz discovered the first planet orbiting a sun-like star outside our solar system – a milestone recognised by this year’s Nobel prize in physics. Today we know of thousands more ‘exoplanets’, and researchers are now trying to understand when and how they form.

Ile des Bermudes An international team of scientists, led by geochemists from the Institute of Earth Sciences at the Université Grenoble Alpes (UGA), presented evidence of an early and unexpected start of crustal recycling in the deep mantle.
Global recycling of oceanic crust from the surface of Earth down to the deep mantle and then back to the surface is one of the major features of the plate tectonic regime, which makes our planet unique in the Solar system. Just when this (…)

The formation of minerals from aqueous solutions is a widespread natural phenomenon that controls mass transfers within the lithosphere, impacting elemental cycling –mostly through interactions with living organisms. Crystallization phenomena have also a high industrial relevance, e.g., for the development of new anti-scaling agents or the synthesis of biomimetic materials.
The process of mineral formation usually involves two consecutive steps –nucleation and growth- that are controlled (…)

Ile des Bermudes Lavas of Bermuda island likely present the first sample of the melt from the Earth mantle transition zone. A study involving the Institut des Sciences de la Terre / OSUG.
The island of Bermuda is the surficial expression of a 1,500-km-long topographic swell, which rises 1 km above a 110–140-Myr-old oceanic crust of Atlantic Ocean. Like many ocean volcanic islands, Bermuda has been historically explained as being derived from a mantle plume- the jet of hot mantle (…)

Peter van der Beek On 28 March, the European Research Council (ERC) published the list of awardees of its Advanced Grants 2019. Among the 222 projects selected (out of 2052 submitted), including 31 based in France and 10 in the Earth and Environmental Sciences, is the project COOLER (Climatic Controls on Erosion Rates and Relief of Mountain Belts) proposed by Peter van der Beek, professor at the ISTerre / OSUG laboratory.
The interactions between tectonics, erosion and climate play (…)
