Talking Points

Recent interactions between the hosts and their guests.

E22 - Part 1: Timing of caloric restriction for longevity with Victoria Acosta-Rodriguez
Q: What is your main perspective looking at lifespan and healthspan from your position at the National Institute on Aging?
We aim to measure various parameters that can be predictive of either accelerated or delayed aging, focusing on behavioral, molecular, and functional changes throughout lifespan.
E22 - Part 1: Timing of caloric restriction for longevity with Victoria Acosta-Rodriguez
Q: Can you talk us through the difference between lifespan and healthspan?
Lifespan is defined as the total time from birth to death, while healthspan refers to the time lived free of disease and in good functional health.
E28 - The Central Clock & Melatonin with Michael Hastings (EBRS 2025 Spotlight 1)
Q: What misconceptions exist about melatonin's role in sleep and circadian rhythms?
A common misconception is that melatonin is primarily a sleep hormone, when in fact, it mainly signals darkness and plays a significant role in regulating seasonal physiological responses.
E28 - The Central Clock & Melatonin with Michael Hastings (EBRS 2025 Spotlight 1)
Q: Can you summarize what circatidal rhythms are and why they are significant?
Circatidal rhythms occur due to the predictable changes in tidal patterns that affect marine organisms' behavior and physiology, ensuring their survival through adaptation to the movements of water in their habitat.
E23 - Part 2: Timing of caloric restriction for longevity with Victoria Acosta-Rodriguez
Q: What are your personal goals in your research career?
To manipulate and understand the aging process related to circadian rhythms at the National Institute on Aging.
