In the spring, when surface snow melts and the top layer of the soil thaws, trapped mercury is released in large quantities and makes its way to the Arctic Ocean, where it is concentrated in the marine fauna. These findings, based on data collected in Alaska over a two-year period, are published in Nature (July 13, 2017).]]> <![CDATA[First discovery of an exoplanet by SPHERE]]> Thu, 06 Jul 2017 01:00:00 +0200 1), the CRAL (Université Claude Bernard Lyon 1/ENS Lyon/CNRS) and the ONERA.

By temporarily modifying the function of Polycomb Group (PcG) proteins—which play an essential role in development—the researchers obtained fruit fly lines having the same DNA sequence but different eye colors. An example of epigenetic inheritance, this color diversity reflects varying degrees of heritable, but reversible, gene repression by PcG proteins. It is observed in both transgenic and wild-type lines and can be modified by environmental conditions such as ambient temperature. The scientists' work is published in Nature Genetics (Monday, April 24, 2017).]]> <![CDATA[When artificial intelligence evaluates chess champions]]> Mon, 24 Apr 2017 01:00:00 +0200 <![CDATA[Smell helps primates flee parasites]]> Fri, 07 Apr 2017 01:00:00 +0200 Science Advances on 7 april 2017, shows that parasites shape the social behavior of these primates, leading them to develop a strategy of parasite avoidance through smell.]]> <![CDATA[Electronic synapses that can learn: towards an artificial brain?]]> Mon, 03 Apr 2017 01:00:00 +0200 Nature Communications on 3 April 2017.]]> <![CDATA[Mini X-ray sensor for high-precision medical applications]]> Thu, 30 Mar 2017 01:00:00 +0200 Optics Letters on March 28, 2017.]]> <![CDATA[CNRS and the Louvre-Lens museum study perception of art with Ikonikat]]> Thu, 23 Mar 2017 00:00:00 +0100 <![CDATA[Gender discrimination: science is no exception]]> Tue, 21 Mar 2017 00:00:00 +0100 eLife on March 21, 2017.]]> <![CDATA[Light-controlled gearbox for nanomachines]]> Mon, 20 Mar 2017 00:00:00 +0100 Nature Nanotechnology on March 20, 2017.]]> <![CDATA[Discovery of an HIV reservoir marker: A new avenue toward eliminating the virus]]> Wed, 15 Mar 2017 19:00:00 +0100 Nature on March 15, 2017.
