Issues

Summary: Wet yeast paste supplemented with cycloheximide, a translation inhibitor, affects Drosophila oogenesis and reduces progeny number. Using this feeding method circumvents confounding effects on oogenesis due to a poor diet.

Summary: Fruit flies exhibited sexual dimorphism and age-related changes in ball rolling-associated locomotor behavior when they were suspended on their wings and provided with a thermocol ball (foam ball).

Summary: Joubert Syndrome gene dysfunction in zebrafish leads to abnormal brain cilia, altered transcription of neuron-associated genes and abnormal swimming behaviour despite normal brain morphology.

Summary: Hummingbirds sustain hovering flight during molt by adjusting wing angles, despite reduced wing area, maintaining weight support as shown in high-speed video analysis of Colombian Andes species.

Summary: Neurogenesis and subsequent apoptosis are thought to conclude perinatally in the PNS. This paper demonstrates that both neurogenesis and apoptosis continue at low levels for weeks after birth. Surprisingly, neurogenesis depends on apoptosis, suggesting that some neurons eliminated during synaptic refinement are replaced.

Summary: When faced with food restriction, short-lived zebra finch parents prioritized current reproduction over maintaining their own body mass, possibly through altering glucose levels.

Summary: The visualization system of fusing fluorescent timers with ubiquitin-like 3 (UBL3), a post-translational modification factor under Tet-on regulation, demonstrated the intracellular dynamics of UBL3.

Summary: The vertical position seems to be less relevant for the hydraulic forces that benthic fish experience in flowing water than body posture and fish movement.

Summary: Quantitative characterization of microfluidic devices for reliable and informative replicative lifespan analysis of budding yeast

Summary: Imaging of biological samples in 3D enables analysis of complex biological structures. We developed a method to enhance autofluorescence with glutaraldehyde for 3D fluorescence imaging and analysis of whole-mount samples.
