When healthy cells stimulate the migration of tumor cells

Featured

Estrogens bind to receptors including GPER, which is generally located in cell membranes. The team of Didier Picard has however discovered a nuclear variant of GPER, which has different properties. This study, published on May 24, 2017 in Oncotarget, reveals that the fibroblasts carrying this variant facilitate the invasiveness of neighboring breast malignant cells.

The liver increases by half during the day

Featured

A study led by Ueli Schibler and Frédéric Gachon showed in mice that the size of the liver increases by almost half before returning to its initial dimensions, according to the phases of activity and rest, in a circadian fashion. Published on May 4, 2017 in Cell, this study describes the cellular mechanisms of this fluctuation, which disappears when the normal biological rhythm is reversed.

Centre de médiation scientifique de la Faculté des sciences de l’UNIGE, le Scienscope regroupe des laboratoires publics et des plateformes pédagogiques dans les domaines de la biologie, la physique, la chimie, les maths et l’astronomie.

Making Sense of Genes

Featured

Making Sense of Genes, the latest book written by Kostas Kampourakis (May 2017), is an accessible but rigorous introduction to contemporary genetics concepts for non-experts, undergraduate students, teachers and healthcare professionals.

‘An extremely intellectual and erudite treatment of the history and meaning of genes and genomes. The book is half hard-core genetics and half provocative and fascinating philosophy of science … cogently written, highly informative and genuinely thought-provoking.’ John Avise, University of California.

Track down water pollution through DNA of algae

Featured

The team of Jan Pawlowski has established a water quality index based solely on the DNA sequences of the diatoms present in the samples, without needing to identify each species visually. This study, published on April 13, 2017 in Molecular Ecology Resources, presents a revolutionary tool to process a very large number of samples in parallel in a reduced time and at a lower cost.
