A research team from the Max Planck Institute for Multidisciplinary Sciences, the Institut Pasteur, and EMBL has shown in a Nature paper how the influenza polymerase, a molecular thief, uses the host RNA to replicate.

Weer tientallen zorgΒ­instellingen ingelijfd door private equity: β€˜Er ontstaan machtsblokken’ Steeds meer zorginstellingen komen in handen van private investeerders. Met goedkeuring van de overheid kochten zij vorig jaar ruim honderd zorgorganisaties op. De Tweede Kamer kijkt machteloos toe.

Jouw tandarts, fysiotherapeut of opticien kan momenteel onderdeel zijn van een internationale investeerder. Private equity koopt in hoog tempo zorginstellingen op, met goedkeuring van de overheid. Maar wat betekent dat voor de prijs, kwaliteit en onze keuzevrijheid als het op zorg aankomt?

I'm thrilled to announce that the manuscript for the Bits to Binders protein design competition is out on bioRxiv! Here's a summary of our findings, including some simple criteria that nearly *double* success rates when applied as a filter 🧡

Introducing our new blood-stage malaria vaccine immunogen based on the essential invasion protein PfCyRPA. By understanding where on PfCyRPA the best antibodies bind, we used structure guided design to generate PfCyRPA-EM, which contains only the epitopes of the best antibodies.

High-resolution in situ structures of hantavirus glycoprotein tetramers The cryo-EM structures of Andes hantavirus (ANDV) glycoprotein tetramers, dimers of tetramers, and ADI-65534 Fab complexes on eVLPs unveil the molecular basis of New World hantavirus glycoprotein architecture, acid-induced membrane fusion, and antibody-mediated neutralization. Immunization with repRNA encoding ANDV-VLPs elicits high neutralizing-antibody titers.

With Eugene Koonin, we propose a concept of β€œthe selfish ribosome”, under which evolution of life is viewed as a ribosomal takeover, where the ribosome evolved to consume most of the cell’s resources, while other cellular componentry ensures the propagation of the ribosome. arxiv.org/abs/2602.23268

Is deze coalitie blind voor het tijdsgewricht? De doorrekening van het coalitieakkoord bevestigde dat de rijken rijker worden en de armen armer. Volgens premier Jetten moeten er misschien nog wat β€˜puntjes op de i’ worden gezet.

Dit gaat niet over het ietsiepietsie aanpassen van koopkrachtplaatjes, dit gaat over het fundamenteel niet verstaan van het tijdsgewricht.

In new study we examine constraints on evolution of endemic "common-cold" coronavirus 229E

We find strong tradeoff between antibody neutralization & receptor binding, due to up-down position of spike RBD

Functional and antigenic constraints on the Nipah virus fusion protein | PNAS Nipah virus is a highly pathogenic virus in the family Paramyxoviridae that utilizes two distinct surface glycoproteins to infect cells. The recept...

In new study led by Brendan Larsen, we map functional constraint across the Nipah virus F protein to define constrained epitopes for antibody targeting and identify mutations that stabilize the prefusion conformation for vaccine immunogens.

Varicella zoster virus and the central nervous system Nature Reviews Microbiology, Published online: 24 February 2026; doi:10.1038/s41579-026-01289-9Varicella zoster virus (VZV) infection causes varicella and herpes zoster and, rarely, severe central nervous system (CNS) complications, including encephalitis. Ogunjimi et al. review the evidence linking herpes zoster with stroke and dementia, summarize innate and adaptive immune responses to VZV-related CNS disease, and debate the consequences of vaccination.
