Source: Laboratory of Jonathan Flombaum—Johns Hopkins University Why is it relatively hard to remember everything on a shopping list if it includes more than just a handful of items? Why is it possible to remember a phone number that one just heard, but not two or three phone numbers at once? Why is it difficult to remember names when several new people are introduced at the same time? The answer has to do with the fact that over short-durations people rely on a specialized memory system...

Spanning Openings in Brick Walls

2024
In brick wall construction, supporting structures are crucial for openings like windows and doors to maintain the integrity and support the weight of the wall above. These supports include lintels, corbels, and arches, each serving specific structural purposes. Lintels are primary supports used to span openings and can be crafted from materials such as reinforced concrete, steel-reinforced brick masonry, or simple steel angles. These are straightforward to install and are typically concealed...

2025
Here, we experimentally compare singly curved and straight piezoelectric transducers embedded in reinforced concrete structures for energy harvesting and structural health monitoring by evaluating their open-circuit voltage, power generation, power storage, and damage detection capability. Curved transducers have surpassed the straight ones, offering better performance for real-world applications.

FAQs
The key distinction is whether added years retain physical, cognitive, and functional capacity. A study can therefore compare survival with measures such as mobility, disease status, cognition, physiological function, and molecular or cellular biomarkers. This separates interventions or biological factors associated with preserved health from those that extend lifespan without maintaining meaningful function.
Each measure captures a different dimension of aging, so combining them provides a broader view of an organism’s trajectory. Mobility may reflect physical function, cognition addresses mental performance, and molecular or cellular biomarkers can indicate biological changes. Together, these measures help connect aging-related mechanisms with observed resilience, decline, or disease status.
Repeated measurements show how health changes within an organism over time rather than relying only on a single observation. This makes it possible to identify gradual decline, preserved function, or differing patterns of resilience. Comparing these trajectories helps researchers determine whether groups or interventions are associated with delayed loss of health-related capacities.
Molecular and cellular biomarkers complement direct assessments of disease, mobility, cognition, and physiological function. Their inclusion allows researchers to examine whether biological changes accompany preserved health or functional decline. Used together, these data connect measurable aging-related processes with outcomes that reflect how well an organism continues to function over time.
A typical analysis begins by selecting health domains relevant to the biological question, such as disease status, mobility, cognition, physiological function, or biomarkers. Researchers then collect these measures longitudinally, track changes across time, and compare aging trajectories between organisms, groups, or experimental conditions. The resulting patterns can distinguish resilience, decline, and preserved function.
Researchers use this approach when survival data alone cannot show whether health has been preserved. It supports comparisons of aging trajectories, investigation of factors linked to resilience or decline, and evaluation of interventions targeting aging-related processes. The findings are relevant to longevity research, disease prevention, and studies seeking healthier aging rather than lifespan extension alone.
