Its origins had remained a mystery until these scientists traced it back to Chalcis (Khalkís), the former port of Thebes. They determined that the town had been a maritime hub from which goods were shipped to Marseille, Acre (in modern-day Israel), and beyond—as far as Chersonesus in Crimea. The team's findings have just been published online by the Journal of Archaeological Science: Reports.]]> <![CDATA[Planck: final data from the mission lends strong support to the standard cosmological model]]> Tue, 17 Jul 2018 01:00:00 +0200 1. The corresponding articles have been submitted to the journal Astronomy & Astrophysics. With its increased reliability and its data on the polarisation of relic radiation2, the Planck mission corroborates the standard cosmological model with unrivalled precision for these parameters, even if some anomalies still remain. For this work the Planck consortium called upon some three hundred researchers, in particular from CNRS, CNES (the French national space agency), CEA (the French Alternative Energies and Atomic Energy Commission) and several universities in France.]]> <![CDATA[CNRS' first overseas subsidiary: CNRS@CREATE, Singapore]]> Fri, 13 Jul 2018 01:00:00 +0200 <![CDATA[CNRS to play major part in ESOF 2018]]> Thu, 05 Jul 2018 01:00:00 +0200 <![CDATA[A molecular label: traceability for medical implants]]> Thu, 05 Jul 2018 01:00:00 +0200 Angewandte Chemie International Edition on July 5, 2018.]]> <![CDATA[Launch of a joint international laboratory between the CNRS and Hitachi High Technologies Corporation]]> Fri, 29 Jun 2018 01:00:00 +0200 <![CDATA[A new twist on how parasites invade host cells]]> Thu, 28 Jun 2018 18:00:00 +0200 Toxoplasma gondii to enter the cells of a host.

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 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 Heliconius numata butterflies to understand how such diversity in color motifs has come about.

However, achieving artificial photosynthesis in solution remains limited by the use of costly and toxic metal-based compounds to harvest light.

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 <![CDATA[A new mathematics museum is taking shape in Paris]]> Thu, 18 Jan 2018 00:00:00 +0100 <![CDATA[Robots aid better understanding of phytoplankton blooms]]> Mon, 15 Jan 2018 11:00:00 +0100 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.
