Sweet and fatty symbionts: photosynthetic productivity and carbon storage boosted in microalgae within a host

This study shows that symbiotic microalgae enhance photosynthetic production and carbon storage within a host, driven by host energetic demands.

Diatom pyrenoids are encased in a protein shell that enables efficient CO2 fixation

This study identifies a protein shell surrounding diatom pyrenoids that enhances CO2 fixation efficiency and reveals its structural and functional role through in vivo and in vitro analyses.

Ultrastructural details of resistance factors of the bacterial spore revealed by in situ cryo-electron tomography

This study uses cryo-electron tomography to reveal the ultrastructural organization of Bacillus subtilis spores, including the toroidal chromosome and nascent coat layers during sporulation.

Correlative transmission electron microscopy and high-resolution hard X-ray fluorescence microscopy of cell sections to measure trace elements concentrations at the organelle level

The paper develops a correlative method combining SR-XRF and electron microscopy to measure trace metal concentrations at the organelle level in cells.

In-cell quantitative structural imaging of phytoplankton using 3D electron microscopy

This paper develops a 3D electron microscopy workflow to generate nanometric phytoplankton models and identifies conserved subcellular features related to energy management.

Visualization of silver nanoparticle intracellular trafficking revealed nuclear translocation of silver ions leading to nuclear receptor impairment

This study visualizes silver nanoparticle intracellular trafficking, revealing nuclear translocation of silver ions that impair nuclear receptors and disrupt liver physiology.
