Nest sharing by birds, or the phenomenon where multiple individuals of different species contribute genetically and parentally to offspring in a single nest, is a rare form of cooperative breeding that has only occasionally been reported in socially monogamous birds. Here we describe, both behaviorally and genetically, the unique case of two female birds, a western kingbird () and a western kingbird × scissor-tailed flycatcher () hybrid, simultaneously occupying (and likely co-incubating eggs in) a single nest. Both females provisioned nestlings, and they did this in two consecutive years (producing four fledglings each year).

The endoplasmic reticulum (ER) comprises an array of structurally distinct subdomains, each with characteristic functions. While altered ER-associated processes are linked to age-onset pathogenesis, whether shifts in ER morphology underlie these functional changes is unclear. We report that ER remodeling is a conserved feature of the aging process in models ranging from yeast to and mammals.

Objective: The Commission on Cancer (CoC) recently introduced a quality metric to optimize time between major head and neck surgery and adjuvant treatment (TAT) ≤6 weeks, as TAT delay adversely impacts patient survival. This study evaluates whether enhanced recovery after surgery (ERAS) for this population reduces the rate of postoperative complications, length of stay (LOS), and TAT.

Methods: Patients undergoing larynx or oral cavity resection with free flap reconstruction, ERAS, and adjuvant treatment after 2018 were compared to a historical pre-ERAS cohort.

Article Synopsis
  • The study investigates how pathologic perivascular spaces (PVS) in the brain relate to cognitive decline in Parkinson's disease (PD), focusing on specific cognitive areas over two years.
  • Researchers used MRI to measure PVS volume in different brain regions, combined with neuropsychological tests assessing various cognitive functions.
  • Results indicated that a higher PVS volume in the basal ganglia correlated with significant declines in attention, executive function, and overall cognitive performance in individuals with PD.

Local protein synthesis in axons and dendrites underpins synaptic plasticity. However, the composition of the protein synthesis machinery in distal neuronal processes and the mechanisms for its activity-driven deployment to local translation sites remain unclear. Here, we employed cryo-electron tomography, volume electron microscopy, and live-cell imaging to identify Ribosome-Associated Vesicles (RAVs) as a dynamic platform for moving ribosomes to distal processes.
