Healing a mother‘s skin lesions using her fetal cells’
Since the end of the 20th century, it has been proven that women who have been pregnant (including those who have miscarried or aborted) store the fetal cells of their children in their bone marrow for at least 50 years. The team of Professor Selim Aractingi - Paris Descartes Faculty of Medicine, Cochin Hospital (Paris hospital group) Dermatology Department, 'Saint Antoine Research Center' Inserm joint research unit, and Université Pierre et Marie Curie - have recently proven that it is possible, in mice, to mobilize these fetal cells to accelerate the healing of chronic skin wounds.

A new approach to forecasting solar flares?
A new approach to forecasting solar flares?
The emerging discipline of space meteorology aims to reliably predict solar flares so that we may better guard against their effects. Using 3D numerical models 1 , an international team headed by Etienne Pariat, a researcher at LESIA (Observatoire de Paris / CNRS / Université Paris Diderot / UPMC), has discovered a proxy that could be used to forecast an eruptive event.

Human intestinal microbiota: progress towards a standardised protocol for the processing of stool samples
Human intestinal microbiota: progress towards a standardised protocol for the processing of stool samples
Obtaining extensive knowledge about human intestinal microbiota and assessing its impact on health requires a standardisation of the metagenomic* methods used. As part of a vast international project, researchers from INRA and the CEA 1 have revealed the major impact of DNA extraction on the evaluation of the microbial composition of human stool samples.

Sound projection: Are Stradivarius violins really better?
Sound projection: Are Stradivarius violins really better?
Researchers at the Institut Jean Le Rond d'Alembert (CNRS/UPMC) have shown that recently-made violins have better sound projection 1 than those built by the famous violinmaker Antonio Stradivarius. This study, published in the journal PNAS on May 8th 2017, also shows that, despite the prestige of these old Italian violins, listeners prefer the sound made by recent instruments and cannot distinguish the two.

Two blood tests for predicting the efficacy of a lung cancer treatment
ALK gene rearrangement is observed in 4% of non-small-cell lung cancer (NSCLC) patients. Researchers from Gustave Roussy, Inserm and Université Paris-Sud, have shown that two blood samples can now predict the efficacy of treatment (crizotinib). These blood samples (taken before treatment initiation and 2 months afterwards) are able to measure the changes in the number of circulating tumor cells (CTC) with a specific genetic abnormality (abnormal number of ALK gene copies).

When liquids turn to solids: the mystery of corn starch elucidated
When liquids turn to solids: the mystery of corn starch elucidated
Some particle suspensions, such as grains of starch in water that are liquid at rest, suddenly solidify when they are subjected to vigorous shearing or impact. This fascinating behavior, called shear thickening, can make it possible to "walk on water" or design lightweight and supple jackets that are nevertheless highly shock-resistant.

When artificial intelligence evaluates chess champions
When artificial intelligence evaluates chess champions
The ELO system, which most chess federations use today, ranks players by the results of their games. Although simple and efficient, it overlooks relevant criteria such as the quality of the moves players actually make. To overcome these limitations, Jean-Marc Alliot of the Institut de recherche en informatique de Toulouse (IRIT - CNRS/INP Toulouse/Université Toulouse Paul Sabatier/Université Toulouse Jean Jaurès/Université Toulouse Capitole) demonstrates a new system, published on 24 april 2017 in the International Computer Games Association Journal.
