Single-molecule imaging of CTCF and cohesin in live cells suggests that chromatin loops are dynamic structures that frequently form and fall apart.

In a minimalistic, generic model of competitive communities in which evolution is constrained by life-history trade-offs, stable biodiversity emerges with species adapted to different functional niches.

Researchers should define in advance the criteria for excluding the results of experiments that 'did not work' from articles.

The first high-resolution structure of a bacterial flagellar cap protein, FliD, reveals new insights into the assembly of bacterial flagella.

The accumulation of its product, cytidine triphosphate, encourages the enzyme CTP synthetase (CtpS) to form large-scale polymers and inhibits the enzyme's activity.

The geometry selection rules of dynamic Min protein patterns are determined in fully confined fluidic chambers, showing that both oscillations and running waves are derivatives of spiral rotations that are established as the majority pattern.

Anarchic, cycling piwi-1+ embryonic cells gives rise to neoblasts, pluripotent stemcells required for development of all organ systems during S. mediterranea embryogenesis, as well as the maintenance andregeneration of tissues during adulthood.

In vitro, in vivo and in silico evidence suggests that bacteria exploit intrinsic chromosomal fluctuations to achieve intracellular transport.

The bacterium Escherichia coli possesses a permissive cytoplasmic environment and the requisite molecular machinery to support the propagation of prions.

Re-characterization of the targets of a commonly used nuclear speckle marker unexpectedly leads to the discovery of the elusive core of the nuclear speckles.
