Gene knockdown experiments in fruit fly pupae reveal the role of the signaling molecule 'dFrizzled2' in the development of a neural circuit that helps insects to fly continuously for extended periods.
Motor neurons controlling the leg of the fruit fly exhibit a gradient of physiological and functional properties that correlate with the order in which they fire during behavior.
Targeted activation of Hedgehog signalling via Gli2 facilitated the reduction of high-fat-diet-induced obesity and improvement of whole-body glucose tolerance and insulin sensitivity in adult mice.
Physiological porphyrin biosynthesis causes photosensitivity in fasted planarians, providing an experimentally tractable animal model of acute porphyrias.
Female mosquitoes are exquisitely sensitive to human body heat, and the TRPA1 gene is required to focus their attraction toward thermal stimuli resembling warm-blooded hosts.
Zebrafish use their sense of gravity and their cerebellum to coordinate the fin and body movements that, as they develop, allow them to better maintain balance as they climb.
X-ray imaging reveals well-preserved internal characters in mineralized arthropods from the Paleogene, urging the reexamination of previously neglected fossil collections.
The exceptionally large size of the human brain is the result of accelerating evolution towards larger brains in hominins, but is not the product of neocortical expansion.
Seasonal variation in resources causes opposing episodes of selection on body size, which interact with density dependence to influence population dynamics.
