Antivirals alter the elastic properties of Hepatitis B Virus capsids
More than 292 million people are chronically infected with the Hepatitis B Virus (HBV), mainly in Africa and South Asia, due to the lack of systematic vaccination. HBV causes severe pathologies such as liver cirrhosis and hepatocellular carcinoma, sometimes leading to the death of almost a million patients …
Sample formation for cryo-EM can be understood from a physico-chemical characterisation of liquid films and interfaces
Cryo electron microscopy (cryo-EM) has become an effective and straightforward approach to determine the structure of macromolecules in solution, trapped within a thin film (a few tens of nanometres) vitrified …

Weaker attraction forces in curved DNA condensates
DNA packaging within viruses, chromosomes or nano-devices leads to extremely compact assemblies where not only high density but also very high curvature prevail. Yet DNA is a rather stiff filament, …
How a virus self-organizes while correcting its errors
RNA viruses are a family of infectious agents with sometimes dramatic health and economic consequences such as those we are currently experiencing. Over the course of a life cycle, viral …

Nucleosome conformational variability in situ and in vitro
In Eukaryotes, DNA is regularly wound into a left-handed super-helix around the histone octamer to form a chain of nucleosomes. Atomic structures have been obtained by crystallography of engineered nucleosomes. …
