Des chercheurs ont créé une sorte de "crayon génomique" qui permet de réécrire le génome à la lettre près. Une technique qui serait plus efficace que les fameux ciseaux moléculaires CRISPR-Cas9.

30 October 2017
En analysant le comportement alimentaire de truites des Iles Kerguelen, des chercheurs de l’Inra ont démontré que ces poissons, carnivores et peu enclins à utiliser des glucides pour favoriser leur croissance, sont pourtant capables de les digérer et les métaboliser. Cette faculté leur a permis de s’adapter aux changements environnementaux, mais aussi de coloniser de nouveaux milieux.

A scientist from the Lomonosov Moscow State University, Faculty of Biology, has, together with his Russian colleague, has explained the frequent occurrence of parthenogenesis development of insects from unfertilized egg cells. Studying this phenomenon could contribute to controlling the species that cause damage to agriculture. The results were published in the Journal of Zoological Systematics and Evolutionary Research.

Bamboo-eating lemurs in Madagascar could be slowly starving as a changing climate slashes the availability of their favorite part of the plant, a new study shows.

27 October 2017
Plant biologists at Lawrence Berkeley National Laboratory (Berkeley Lab), in collaboration with colleagues from the California Institute of Technology (Caltech), have reconstructed the evolutionary history of photosynthesis to provide new insight into the yet-unfolding story of its origins.
