In-cell structure and snapshots of copia retrotransposons in intact tissue by cryo-electron tomography

This study uses cryo-ET to visualize copia retrotransposon structure in Drosophila cells, revealing nuclear clustering and size selection during gametogenesis.

Nuclear pores safeguard the integrity of the nuclear envelope

This study shows that nuclear pore complexes dilate during cell differentiation and that Nup133 deficiency prevents this dilation, leading to nuclear envelope instability.

Effects of water nutrient concentrations on stream macroinvertebrate community stoichiometry: a large-scale study

This study examines how water phosphorus and nitrogen levels affect stream macroinvertebrate community stoichiometry using a large dataset from France.

Nuclear pores as conduits for fluid flow during osmotic stress

This study shows that Dictyostelium discoideum uses nuclear pores as conduits for fluid flow during osmotic stress, distinct from passive diffusion and active transport.

Thinner is not always better: Optimising cryo lamellae for subtomogram averaging

This study benchmarks cryo-ET resolution based on lamella thickness and particle depth, showing no negative impact up to 180 nm and ion-induced damage extending 30 nm from surfaces.

The killing of human gut commensal E. coli ED1a by tetracycline is associated with severe ribosome dysfunction

The paper examines how tetracycline affects ribosome function in two E. coli strains, showing different outcomes based on the antibiotic's bacteriostatic or bactericidal effect.

Translation dynamics in human cells visualized at high-resolution reveal cancer drug action

The paper visualizes ribosome dynamics in human cells at near-atomic resolution, revealing how a cancer drug alters translation.

miR-29 is an important driver of aging-related phenotypes

This study identifies miR-29 as a key driver of aging-related phenotypes by showing its upregulation in aging models and its ability to induce aging traits when overexpressed.

Bacterial cell widening alters periplasmic size and activates envelope stress responses

This study shows that changes in bacterial cell width affect periplasmic thickness and activate the Rcs stress response system through RcsF.
