Federal research funding delays and policy shifts are putting science careers and innovation at risk.

Look at me. I’m the originalist now.

And blowing its credibility in the process.

Endurance training is known to elicit numerous changes in skeletal muscle to enhance performance and function. Many of these adaptations are controlle…

Facing an extreme budget, the National Academies hosted an event that ignored it.

Many countries face an unprecedented challenge in aging demographics. This has led to an exponential growth in research on aging, which, coupled to a massive financial influx of funding in the private and public sectors, has resulted in seminal insights into the underpinnings of this biological process. However, critical validation in humans has been hampered by the limited translatability of results obtained in model organisms, additionally confined by the need for extremely time-consuming clinical studies in the ostensible absence of robust biomarkers that would allow monitoring in shorter time frames. In the future, molecular parameters might hold great promise in this regard. In contrast, biomarkers centered on function, resilience, and frailty are available at the present time, with proven predictive value for morbidity and mortality. In this review, the current knowledge of molecular and physiological aspects of human aging, potential antiaging strategies, and the basis, evidence, and potential application of physiological biomarkers in human aging are discussed.

Opinion: It’s time for public resistance.

Regular physical activity induces a variety of health benefits, preventing and counteracting diseases caused by a sedentary lifestyle. However, the mo…

Early clinical trials suggest that people who lose weight with drugs like Ozempic lose lean mass as well as fat, which could have consequences for older adults at risk of muscle loss.

Exercise training involves repeated exposure to increases in metabolic, thermal, mechanical, and oxidative stress. This exposure stimulates physiological adaptations that improve tolerance to similar ...
