The fruit fly estimates visual motion by incorporating ON-OFF asymmetric processing that only improves performance when stimuli have light-dark asymmetries matched to natural scenes.

A common mechanism for computation of direction selectivity in the ON and OFF channel is demonstrated.

Open data provides an opportunity to perform new analyses on preexisting data, but trade-offs are required to limit an increase in false positives.

A text-mining study suggests that about half of the papers reporting the results of experiments on mice do not report the sex and age of the mice.

The consequences of real-world biodiversity change for ecosystem functioning depend on the type of global change driver and can be particularly significant when human activities decrease biodiversity.

Rarity metrics reveal pervasive negative impacts of agricultural land use on soil invertebrate communities, whereas widely-used richness and diversity metrics underestimate the magnitude of these impacts.

Any effects of environmental 50/60 Hz magnetic fields on human biology due to a radical pair mechanism should be no more dangerous than those incurred by travelling a few kilometres.

Casein kinase Iε phosphorylation has opposite effects on the stability of the core planar polarity proteins Strabismus and Dishevelled, leading to their sorting to opposite cell ends.

Rigorous reanalysis of single-molecule data yields evidence for energy expenditure in the interaction of transcription factors on DNA.

A fundamental lower-bound on memory recall precision, which declines with storage duration and number of stored items, is derived, and human performance is shown to be well-fit by this theoretical bound.
