How females shut off their second X chromosome, fMRI scans on autism-model mice and 2000-year old date seeds germinated

The protein SPEN plays a crucial role in the inactivation of the X-chromosome, whereby female mammalian embryos silence gene expression on one of their two X chromosomes. This new result from researchers at the European Molecular Biology Laboratory (EMBL) in…

Metallic hydrogen, zinc nano-fillers capable of recycling CO2 and treating trauma through false memories

Although predicted in 1935, making metallic hydrogen has proved to be extremely difficult in practice. Researchers have tried to create it in the lab by squeezing tiny samples of hydrogen gas between the tips of two diamonds. These miniature anvils…

An Inca god’s colours revealed, Corsican granite and the Roman Empire, and a new way to regulate the expression of RNA genes

Researchers from the CNRS, Sorbonne Université, Université Paris 1 Panthéon-Sorbonne, the Muséum National d’Histoire Naturelle and the Musée du Quai Branly – Jacques Chirac have used X-ray fluorescence spectrometry to analyze the colours painted on a statue of the Inca god and oracle Pachacamac. This measurement, combined with…

Excess calorie intake early in life leads to colitis later on, how E. coli gain a foothold and haematopoietic stem cells produced in transient waves

Thanks to epidemiological studies, researchers now know that obesity and inflammatory bowel disease (IBD) are linked. Animal models also show that a maternal high-fat diet and maternal obesity make offspring more likely to be obese. A team at the Institut…

Global soil erosion already a problem 4000 years ago, traffic champion ants and strategies for placing future hydropower dams

Soil erosion reduces the productivity of ecosystems, changes nutrient cycles and thus directly impacts climate and society. An international team of researchers, including Pierre Francus at the Institut National de la Recherche Scientifique (INRS) and INRA at the Université Savoie Mont Blanc have…

P0 protein sacrificed by a virus, how a molecule can change the climate and catastrophic events carry tree forests thousands of miles

In plants, interference by RNA (or RNAi) is one of the major defence mechanisms against viruses. At the heart of this machinery, the Argonaute1 protein (AGO1) is the target of certain viral proteins called RNAi suppressors (VSR) such as the…
