Virtual reality experiments show that motorists slow down when driving in fog, but they speed up when visibility is reduced equally at all distances.

The structure of the recombination complex responsible for flagellar antigen switching in Salmonella enterica, and the mechanism that regulates the site-specific DNA inversion reaction, have been determined.

A stable tetrameric nucleosome occupies the central segment of each ∼120-bp budding yeast centromere in two rotational phases of both reflectional orientations in vivo.

Brassinosteroids signal through a pathway involving GSK3-like kinases and the WER-GL3/EGL3-TTG1 transcription factor complex to determine the fate of cells in the root epidermis.

Adapting a cytosolic enzyme that breaks down glutathione to function in the lumen of the endoplasmic reticulum challenges the long-held view that reduced glutathione fuels disulfide rearrangements during protein folding.

Empirical evidence suggests that the hippocampus constructs maps of spatial environments based on the relative locations of places (i.e., topology), rather than absolute distances and coordinates (i.e., geometry).

Fringe proteins modulate cis inhibitory, same-cell interactions between the Notch receptor and its ligands to control whether, and in which direction, cells can signal to one another.

Comprehensive structural and compositional characterization of the in vivo 30S ribosomal assembly landscape reveals parallel pathways for 3′-domain formation and a previously unknown role for the assembly factor RimP.

Storage of long-term memory in Aplysia does not require stable synapses.

Loss-of-heterozygosity mutations, but not aneuploidies, are linked to the evolution of drug resistance in Candida albicans isolated from immunocompromised patients.
