Lipocalin-2 is a strong predictor of hunger scores, reflects an anti-obesity response that is deregulated in severely obese subjects, and exerts an anorexigenic function with a conserved interspecies mechanism.
A new tool to visualize blood-feeding mosquitoes in high resolution and quantitatively characterize their behavior sheds light on contact-dependent sensing and blood-feeding dynamics of several medically relevant mosquito species.
Transposable elements are not reactivated in natural hybrids of the yeast Saccharomyces paradoxus, but their accumulation is genotype-specific and is not predicted by the evolutionary divergence between a hybrid's parents.
Spontaneous growth arrest of transformed melanocytes (resulting in benign “moles”) does not result from cell-autonomous oncogene-induced senescence, but can be explained by collective mechanisms used in normal tissue size control.
To improve the reliability of transmitting small single-photon voltage responses, rod photoreceptor cells release synaptic vesicles in regularly timed multivesicular events that are exquisitely sensitive to small voltage changes.
