Biodiversity loss and climate change must be addressed together
A recent report, co-authored by experts on climate change (IPCC) and biodiversity loss (IPBES) shows that these two phenomena are closely related. And although some solutions put forward to tackle either of the two may prove detrimental to the other, t…
Profiling sharks to eliminate killers
Dividing his time between France and Polynesia, the ichthyologist Éric Clua devotes his efforts to studying sharks, both to preserve their populations and to help prevent attacks on humans.

Investigating one of the cradles of humankind
The fossiliferous site of Bolt’s Farm, in South Africa, spans millions of years of history, including episodes of climate change that impacted early hominids and their environment. To study it, researchers from the country’s National Research Foundatio…
Research on HIV has reached a turning point
Forty years after its discovery, HIV-AIDS has become a chronic disease thanks to triple therapies. Yet there is still no known cure for it and a vaccine is nowhere in sight. Monsef Benkirane, a virologist at the Institute of Human Genetics (IGH), gives…
Black holes and neutron stars meet up with a bang
The LIGO and Virgo observatories have announced the very first sightings of the merger of a black hole and a neutron star. These discoveries should help gain a better understanding of how these compact bodies form and evolve.
The forest of Fontainebleau is home to rock art treasures
With more than 2 000 engraved shelters, the forest of Fontainebleau is home to one of Europe’s largest rock art complexes. A research mission in the Paris region is focusing on geometric engravings, believed to date back to the Mesolithic (11 500 BP to…
The story of AIDS, from fear to fight
The first identified cases of AIDS, in 1981, caused an outbreak of panic, along with widespread discrimination. Since medical science initially proved powerless, people with AIDS and support groups campaigned vigorously for access to treatment and demo…
Jean Dalibard receives the CNRS 2021 Gold Medal
A brilliant physicist and a leading specialist in cold atoms, an area that is central to light-matter interaction, Jean Dalibard has been awarded the CNRS 2021 Gold Medal, one of France’s highest scientific distinctions.
Leading CNRS project on hybrid AI launched in Singapore
A vast collaborative project on hybrid artificial intelligence, led by the CNRS’s subsidiary in Singapore and allocated a budget of €35 million over five years, will begin in late 2021.
How optogenetics has restored partial sight to a blind patient
Thanks to gene therapy and the use of adapted spectacles, a blind patient is now able to distinguish the shape of objects to recognise, count and grasp them. José-Alain Sahel, the lead author of this study published in Nature Medicine and a founding me…
Forthcoming revolution will unveil the secrets of matter
Provided adapted software can be developed, exascale computing, a new generation of supercomputers, will offer massive power to model the properties of molecules and materials, while taking into account their fundamental interactions and quantum mechan…
Why the “Gulf Stream” is a misnomer
At school, we learned that the Gulf Stream was the warm current that flows across the Atlantic. Yet according to oceanographer Julie Deshayes, things aren’t quite so simple. The scientist prefers to speak of the “Atlantic Overturning Circulation” to de…
The poles at the centre of the world stage
At first sight, the remote, icy polar regions may appear superficially similar. But they are in fact very different places: the Antarctic and the Arctic have neither the same history nor the same legal status. CNRS News takes a look at the geopolitical…
Fariba Adelkhah’s struggle for freedom
Arrested in Tehran two years ago and sentenced to five years of detention, the French-Iranian anthropologist has been released from prison but remains under house arrest. She was recently awarded the Irène Joliot-Curie Prize for “Female Scientist of th…
Targeted political advertising raises a number of issues
What can we do when a technology created to promote commercial products is used to influence people’s political opinions?
Bioinformatics, a key ally in the fight against Covid-19
Bioinformatics—a relatively new scientific discipline—uses models and algorithms to analyse the avalanche of data produced by biologists. It has played a crucial role in deciphering the origin and functioning of the SARS-CoV-2 coronavirus
Chemists in the GAVO project set out to tackle viruses
Because viruses can only replicate their genetic material by hijacking cell machinery, focusing on this crucial step may halt the infection. Scientists are collaborating within the GAVO project to synthesise molecules that could block the replication o…
Comment les artères et les veines trouvent-elles leur chemin au cours du développement ?
Des chercheurs du CNRS, de l’Université Paris Diderot et de l’Université Paris Descartes viennent de montrer comment s’organise la croissance des veines et des artères au cours du développement embryonnaire. Leurs observations prouvent en outre que, co…
