A sobering conclusion: Adult hearts contain no stem cells
Marie Bannier, a former normal student in the Biology Department at the ENS de Lyon, participated in the research and writing of this scientific publication as part of her 4th year. During a myocardial infarction, commonly known as a heart attack, the blood supply to part of the heart muscle is cut off.

Unsaddling old theory on origin of horses
Botai horses were tamed in Kazakhstan 5,500 years ago and thought to be the ancestors of today's domesticated horses. . . until a team led by researchers from the CNRS and Université Toulouse III–Paul Sabatier sequenced their genome. Their findings published on 22 February 2018 in Science are startling: these equids are the progenitors not of the modern domesticated horse, but rather of Przewalski's horses—previously presumed wild! The earliest proof of equine domestication points to the steppes of Central Asia roughly 5,500 years ago.

At a global scale, just 12 grape varieties (or 1% of cultivated varieties) occupy up to 80% of vineyards in some countries. Scientists from INRA and Harvard University in the USA have suggested that one of the levers that could be operated to adapt wine-growing to climate change is to exploit the diversity of other cultivated varieties by planting those that are less well known, and thus encouraging winegrowers and consumers to adopt new practices.

GlutN: understanding gluten sensitivity to offer suitable wheat-based products
Coordinated by INRA, the GlutN Project aims to explore the mechanisms of non-celiac gluten sensitivity (NCGS), assess its prevalence and identify clinical markers with the goal of developing suitable bread products. The GlutN Project was launched on 30 January 2018 in Paris. Found in the grains of numerous cereals, including wheat, gluten is a composite of proteins which gives flour the viscoelastic properties it needs to add shape to bread products.

Tara Oceans : discovery of over 100 million genes from the marine world
The 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.
