Genetic and microscopy analyses identify a programmed cell death mechanism that kills a cell subpopulation in a bacterial biofilm where oxygen is limiting, thereby promoting dispersion of newborn motile cells through the action of DNA released by dead cells.

Molecular details of how the iron–sulfur cluster cofactor of a bacterial global iron regulatory protein simultaneously senses iron and O₂ are revealed by mass spectrometry and spectroscopy.

The endosymbiosis between an alga and the spotted salamander shows several parallels to invertebrate-algal symbioses as well as to pathogen associations in vertebrate animals.

Compared to non-burn tissue, T cells in burn tissue have a pro-inflammatory rather than a homeostatic tissue-resident phenotype, and unconventional T cells in burn tissue have a higher cytotoxic capacity.

Pupil difference during bistable perception of bright and dark elements predicts autistic traits.

Visualization of yeast spindle pole proteins using a new microscopy method shows that assembly into the nuclear membrane occurs at the same time as duplication.

Two novel subsets of microglia identified by their unique autofluorescence profiles differ in their subcellular organization, proteomic signatures and in their response to aging and lysosomal dysfunction.

An unbiased genome-wide human forward genetic screen identifies the vacuolar ATPase complex and assembly factors as regulators of HIF stability through their actions on intracellular iron metabolism.

The mathematical model incorporating new parameters explains multimodal distributions in escape direction (i.e., multiple preferred escape trajectories), which are previously observed in various animal taxa.

Pupillometry tracks individual differences linked with autistic traits independently of illusion susceptibility and perceptual reports.
