Navelbine and Taxotere : Histories of Sciences
Weaving history with chemistry, Navelbine and Taxotere : Histories of Sciences (ISTE Editions, June 2017) tells the story of two anticancer drugs—both of natural origin—discovered by teams of researchers at the CNRS Institut de Chimie des Substances Naturelles (ICSN).

Phage therapy : synergy between bacteriophages and the immune system is essential
Phage therapy involves the use of bacteriophages, or phages, for treating bacterial infections. Phages are viruses that specifically attack bacteria and are harmless to humans. A significant decline in the use of this therapeutic strategy introduced 100 years ago was seen in the West following the development of antibiotics.

First discovery of an exoplanet by SPHERE
First discovery of an exoplanet by SPHERE
The astronomical instrument SPHERE, installed since 2014 on the Very Large Telescope (VLT) of the European Southern Observatory (ESO) in Chile, has made its first discovery of a planet around a star other than the Sun, known as an exoplanet. Only a handful of the 3,600 exoplanets detected since 1995 have been observed directly in this way.

A major advance towards a treatment for accelerated ageing
In a study published today in the journal EMBO Molecular Medicine1, the team led by Prof. Nicolas Lévy identifies the mechanism associated with the accumulation of progerin, a toxic protein produced in the course of ageing, and demonstrates the therapeutic potential of a new drug - MG132 - to treat progeria, a rare syndrome involving premature and accelerated ageing.

Brooding dinosaurs
Brooding dinosaurs
A new method used to perform geochemical analysis of fossilized eggs from China has shown that oviraptorosaurs incubated their eggs with their bodies within a 35–40° C range, similar to extant birds today. This finding is the result of Franco-Chinese collaboration coordinated by Romain Amiot of the Laboratoire de géologie de Lyon: Terre, planètes et environnement (CNRS/ENS de Lyon/Université Claude Bernard Lyon 1).

Omega-3 Essential for the Brain from Adolescence into Adulthood
Omega-3 fatty acids are crucial for the brain. Deficiency in these acids can lead to depressive mood. A new study led by Inserm and Inra researchers from Unit 901, 'Mediterranean Institute of Neurobiology' (Inserm/Université d'Aix-Marseille) and UMR 1256, 'Nutrition and Integrated Neurobiology' (Inra/Université de Bordeaux) reveals the mechanisms of disease that develop in adult mice on a low omega-3 diet since adolescence.

Discovery of a new mechanism involved in the migration of cancer cells
A team of young researchers under the supervision of Guillaume Montagnac, Inserm research leader at Gustave Roussy, in collaboration with the Institut Curie and the Institut de Myologie ( Myology Institute ), has discovered a new mechanism which facilitates cell migration.

How phytoplankton rule the oceans
Photosynthesis is a unique biological process that has permitted the colonization of land and sea by plants and phytoplankton respectively. While the mechanisms of photosynthesis in plants are well understood, scientists are only now beginning to elucidate how the process developed in phytoplankton.

Neuronal Self-Defense Against Alzheimer’s Disease
It is known that IGF-1 ( insulin-like growth factor ) is needed for development and also plays a role throughout the body's life. Previously, the team led by Martin Holzenberger (Inserm/UPMC Unit 938, Saint-Antoine Research Center) has shown that this hormone is involved in longevity and in Alzheimer's disease.

What the pupils tells us about language
What the pupils tells us about language
The meaning of a word is enough to trigger a reaction in our pupil: when we read or hear a word with a meaning associated with luminosity (“sun,” “shine,” etc.), our pupils contract as they would if they were actually exposed to greater luminosity. And the opposite occurs with a word associated with darkness (“night,” “gloom,” etc.).

Prenatal stress affects life expectancy in offspring
Major prenatal stress reduces the lifespan of adult offspring by over 2 years. Inserm researchers have obtained these results by studying a cohort of children born between 1914 and 1916, some of whom lost their father in combat before they were even born. Stress suffered by the mother seems to weaken the fetus, at a developmental stage characterized by a high level of plasticity.

Blood test developed to detect rare neurological disease
Teams from the AP-HP Paris public hospitals network, in collaboration with researchers from the Brain & Spine Institute (ICM) (Inserm/CNRS/UPMC), and Metafora biosystems, a start-up with links to the CNRS, have recently developed a diagnostic blood test for a rare but treatable condition called De Vivo disease.

Weâ?‘re all a bit Neanderthalâ’’ or are we?
A study conducted by Inserm researchers at the Research Institute for Environmental and Occupational Health (Irset) has shown that natural selection has â?'purgedâ'' our bodies of many of the traces of our ancient Neanderthal and Denisovan cousins in the genes responsible for the genetic mixing essential to reproduction.

The secrets of tooth calcium revealed
The secrets of tooth calcium revealed
Two studies on calcium isotopes 1 in teeth have provided new insights into both the extinction of the dinosaurs and weaning age in humans. The findings of these studies, conducted by CNRS researchers at Lyon ENS and Université Claude Bernard Lyon 1, were published, respectively, on 25 and 30 May 2017 in Current Biology and PNAS .

Assessing human weaning practices with calcium isotopes in tooth enamel
Assessing human weaning practices with calcium isotopes in tooth enamel
Weaning practices differ among great apes and likely diverged during the course of human evolution, but behavioral inference from the fossil record is hampered by a lack of unambiguous biomarkers. Here, we show that early-life dietary transitions are recorded in human deciduous tooth enamel as marked variations in Ca isotope ratios (?44/42Ca).
