Article Synopsis
- Climate variability affects marine ecosystems, influencing the diet and migration of North Atlantic fin whales.
- Researchers conducted stable isotope analysis on baleen plates of 29 fin whales to track their dietary habits and migration patterns over time.
- Findings reveal that climate patterns, such as the North Atlantic Oscillation and Atlantic Multidecadal Oscillation, lead to shifts in whale diets towards higher trophic resources and changes in migratory routes, demonstrating the species’ adaptability to climate changes.
Background: Transcatheter aortic valve replacement (TAVR) is an effective treatment for aortic valve disorder. Several studies have reported improvements in systolic and diastolic function following TAVR. However, few studies have addressed immediate post-deployment changes.

A better understanding of how age-related bone loss affects the fracture-prone regions of the proximal femur could lead to more informed fracture-prevention strategies. Therefore, the aim of this work was to assess the spatio-temporal distribution of bone deterioration in older men and women with aging. A subset of 305 men (74.
