New experiments and theory reveal how the ability to see image details depends upon photoreceptor function and eye movements, and how fruit flies (Drosophila) see spatial details beyond the optical limit of their compound eyes.
The involvement of SETD2 in an important DNA repair pathway could explain the high frequency of SETD2 mutations in several cancers and may provide an alternative mechanism to evade the p53-mediated checkpoint.
SAK1, a novel cytoplasmic phosphoprotein, is a key intermediate component of the retrograde signaling pathway controlling nuclear gene expression during acclimation of Chlamydomonas cells to singlet oxygen stress.
A molecular atlas of the chick retina provides a comprehensive classification and characterization of 136 cell types, yielding novel insights into retinal structure, function, development, and evolution.
Parallel losses of short-wave light sensitivity in diverse bats occurred through independent changes at multiple steps in the conversion of genotype into functional phenotype, including pre-, during, and post-transcription.
As in humans, Drosophila hearts are able to maintain contractile performance during healthy aging, but this maintenance is associated with an increased susceptibility to progressive dysrhythmias that can lead to fibrillatory arrest.
