Mitochondrial Derived Vesicles retain membrane potential and contain a functional ATP synthase

The paper isolates and characterizes Mitochondrial Derived Vesicles (MDVs) from yeast, showing they contain functional ATP synthase and membrane potential, suggesting a role in organelle communication.

Imaging Flow Cytometry reveals a dual role for exopolysaccharides in biofilms: To promote self-adhesion while repelling non-self-community members

The paper uses imaging flow cytometry to show exopolysaccharides in Bacillus subtilis promote self-adhesion while repelling non-self bacteria like Bacillus mycoides.

The Serine Protease HtrA2 mediates radiation-induced senescence in cancer cells

This study identifies HtrA2 as a mediator of radiation-induced senescence in cancer cells, showing its role in proliferation arrest and vimentin filament reorganization.

Clump sequencing exposes the spatial expression programs of intestinal secretory cells

ClumpSeq reconstructs spatial atlases of rare intestinal cell types by sequencing small clumps of attached cells and inferring their position along the crypt-villus axis.

Visualizing active viral infection reveals diverse cell fates in synchronized algal bloom demise

The paper quantifies active viral infection in algal blooms using a novel method called Virocell-FISH, revealing that only a quarter of Emiliania huxleyi cells are infected despite synchronized bloom demise.

{-}{-}{-}{-}{-}Polyglutamine-related aggregates serve as a potent antigen source for cross presentation by dendritic cells

The paper shows that polyglutamine-related aggregates from apoptotic cells are efficiently processed by dendritic cells for cross-presentation, ensuring antigenic overlap necessary for T cell immunity.
