These nutrients are scarcely found in the blood ticks ingest but are essential to their life cycle. Thus ticks cannot survive to adulthood or reproduce without their bacterial symbionts. The study conducted by CNRS and CIRAD researchers has also shown that the bacteria inherited their B vitamin synthesis pathways from a pathogenic ancestor whose genome underwent gradual degradation.]]> <![CDATA[First light for SPIRou, exoplanet hunter]]> Mon, 28 May 2018 01:00:00 +0200 http://www2.cnrs.fr/en/3123.htm 1 (CNRS/CNES/Université de Toulouse III - Paul Sabatier) before being shipped to Hawaii.]]> <![CDATA[A supergene to stay alive]]> Thu, 24 May 2018 16:00:00 +0200 http://www2.cnrs.fr/en/3119.htm Heliconius numata butterflies to understand how such diversity in color motifs has come about.

Although some signs of bleaching had been observed on their route, the reefs of Upolu proved to be in a far more degraded state: coral cover is below 10% in over 80% of the 124 sites considered. According to the scientists, this situation can be explained by a combination of global and local factors. Their study is published in the journal Marine Pollution Bulletin.]]> <![CDATA[The dinosaur menu, as revealed by calcium]]> Wed, 11 Apr 2018 01:00:00 +0200 http://www2.cnrs.fr/en/3101.htm Proceedings of the Royal Society of London B.]]> <![CDATA[Cheaper, less toxic and recyclable light absorbers for hydrogen production]]> Tue, 10 Apr 2018 01:00:00 +0200 http://www2.cnrs.fr/en/3099.htm 2 into a high energy fuel (hydrogen) or into chemicals of industrial interest, is a major research challenge today. However, achieving artificial photosynthesis in solution remains limited by the use of costly and toxic metal-based compounds to harvest light. Researchers at CNRS, CEA and the Université Grenoble Alpes propose an efficient alternative using semi-conductor nanocrystals (also called quantum dots) based on cheaper and less toxic elements, such as copper, indium and sulfur.

Its beneficial effect on lifespan had been established for many short-lived species (worms, flies, mice), but remained controversial for primates, including humans. Another observation is that the aging process is delayed among animals on a reduced diet.

This is a new indicator of the “great acceleration”: an increasingly rapid inflation of different parameters around the world (glacier retreat, coral bleaching, etc.) seen in recent years as a result of climate change. Mountain ecosystems could be seriously disturbed as a result.

Conversely, cities that are less organized, like those founded long ago, shed heat easily. The team's findings, published in Physical Review Letters (March 9, 2018), suggest new directions to explore for optimal urban planning and energy management.]]> <![CDATA[A new solution for chronic pain]]> Mon, 12 Mar 2018 00:00:00 +0100 http://www2.cnrs.fr/en/3073.htm Nature Communications.]]> <![CDATA[Comet Chury formed by a catastrophic collision]]> Mon, 05 Mar 2018 00:00:00 +0100 http://www2.cnrs.fr/en/3071.htm 1), was published on 5 March 2018 in Nature Astronomy.]]> <![CDATA[Ancient Nubia (present-day Sudan): In the footsteps of the Napata and Meroe kingdoms]]> Mon, 05 Mar 2018 00:00:00 +0100 http://www2.cnrs.fr/en/3069.htm 1 mixing local traditions and Egyptian influences.

This work has enabled the scientists to develop a model capable of predicting the maximum energy that can be released during a solar flare, which could have potentially devastating consequences for the Earth.]]> <![CDATA[Tara Oceans: discovery of over 100 million genes from the marine world.]]> Thu, 25 Jan 2018 11:00:00 +0100 http://www2.cnrs.fr/en/3057.htm Tara Oceans expedition (2009-2013) has enabled the collection of plankton samples in all of the world's oceans on board the schooner Tara, and the creation of catalogues of species and genes on a scale never before undertaken. Continuing the analysis and exploitation of the biggest database compiled on the planktonic ecosystem, the teams from the CEA, CNRS (French National Centre for Scientific Research), EMBL (European Molecular Biology Laboratory) and the French graduate school ENS, among others1, have just reached a new milestone by analysing the expression of over 100 million genes belonging to complex organisms, from microscopic algae to small planktonic animals. These teams have demonstrated that very different genes express themselves depending on the water temperature or the concentration in nutrients of the oceanic areas studied. Half of these genes are unknown, indicating that the ocean - which is already a marvellous breeding ground of biodiversity - harbours, at the same time, an enormous potential of genetic functions awaiting discovery. By using isolation and characterisation methods of isolated cells, the researchers have, more specifically, been able to explore the role of the genes present in a little-studied, uncultivated but very abundant compartment of the plankton - the first link in a long food chain. These results are the subject of two articles published in the journal Nature Communications on 22 and 25 January 2018.]]> <![CDATA[Antoine Petit named Chairman and CEO of the CNRS]]> Wed, 24 Jan 2018 00:00:00 +0100 http://www2.cnrs.fr/en/3055.htm <![CDATA[A new mathematics museum is taking shape in Paris]]> Thu, 18 Jan 2018 00:00:00 +0100 http://www2.cnrs.fr/en/3053.htm <![CDATA[Robots aid better understanding of phytoplankton blooms]]> Mon, 15 Jan 2018 11:00:00 +0100 http://www2.cnrs.fr/en/3047.htm 1 project, led by researchers at the Laboratoire d'Océanographie de Villefranche (CNRS/UPMC), has developed a new class of robots: biogeochemical profiling floats, the first robots able to collect data in the ocean throughout the year.
