The DocMaps Framework for representing assertions on research products in an extensible, machine-readable, and discoverable format

The paper proposes a framework for representing machine-readable, extensible, and discoverable assertions about research products and editorial processes.

Preprints in motion: tracking changes between preprint posting and journal publication during a pandemic

The paper tracks changes between preprint and published versions of biomedical articles during the pandemic, finding limited structural changes and minor conclusion modifications.

A systematic examination of preprint platforms for use in the medical and biomedical sciences setting

This paper examines 44 biomedical and medical preprint platforms, comparing their characteristics, policies, and providing a searchable database for stakeholders.

Preprinting the COVID-19 pandemic

This study analyzes the role of preprints in the dissemination of COVID-19 science, finding increased engagement, faster review, and greater sharing of preprints related to the pandemic.

Cryo-EM structure of the bacterial actin AlfA reveals unique assembly and ATP-binding interactions and the absence of a conserved subdomain

The paper reports the cryo-EM structure of AlfA, a bacterial actin, revealing unique ATP-binding interactions and a missing subdomain that explain its distinct assembly dynamics and plasmid segregation function.

Bacterial Microtubules Exhibit Polarized Growth, Mixed-Polarity Bundling, and Destabilization by GTP Hydrolysis

This study characterizes bacterial microtubules (bMTs) from Prosthecobacter, showing polarized growth, mixed-polarity bundling, and GTP-dependent destabilization, suggesting ancestral eukaryotic tubulin dynamics.

Super-resolution microscopy of the β-carboxysome reveals a homogenous matrix

The paper uses super-resolution microscopy to study CcmM isoform localization in carboxysomes, finding both isoforms colocalize, revising the internal arrangement model.
