The proteins that domesticated our genomes

Chromatin immunoprecipitation (ChIP-exo) data obtained in this study, mapping sites of interest. Credit: Didier Trono/EPFL EPFL scientists have carried out a genomic and evolutionary study of a large and enigmatic family of human proteins, to demonstrate that it is responsible … Continue reading

See how Zika infection changes a human cell

This visual abstract depicts the findings of Cortese et al., who show that Zika virus infection in both human hepatoma and neuronal progenitor cells induces drastic structural modification of the cellular architecture. Microtubules and intermediate filaments surround the viral replication … Continue reading

New link found between sex and viruses

This pair of ‘ribbon diagram’ images compares the three-dimensional structures of two closely related proteins, determined by X-ray crystallography: (L) the HAP2 protein from the single-celled alga Chlamydomonas reinhardtii and (R) the fusion protein from dengue virus. Both proteins are … Continue reading

New study shows how plants fight off disease

Hypothetical structural model of the assembly of TIR domains during signalling, from the SNC1 immunity receptor found in Arapidopsis plants. Individual subunits are shown in different colours, with β-strands shown as arrows and α-helices shown as cylinders. Credit: Bostjan Kobe … Continue reading

The science of baby’s first sight

UNC scientists conduct seminal experiments to unveil how early-in-life visual experiences – simply trying to see – sculpt a particular subnetwork of brain circuitry we need in order to see properly. When a newborn opens her eyes, she does not … Continue reading

How bacteria survive antibiotic treatment

Multiresistant bacteria Scientists around the world are working hard to win the battle against multi-resistant bacteria. A new publication from the BASP Centre, University of Copenhagen now presents how even sensitive bacteria often manage to survive antibiotic treatment as so-called … Continue reading

The gene of autumn colours

SGR induces colour changes in leaves. SGR was experimentally induced (bottom) in Arabidopsis and compared with the normal leaves (top). Excised leaves were observed for up to 30 hours. Credit: Shimoda Y et al., Plant Cell, September 7, 2016 Researchers … Continue reading

How cells move
