Going forward, AI has the potential to help balance needs across regions, ensuring care delivery doesn’t compromise chronic or long-term care in the face of emergencies.
Ethical Considerations And Systemic Impact
While AI holds significant promise in healthcare, its implementation must be approached thoughtfully. Challenges such as bias in training data, lack of interoperability and concerns around patient consent and data privacy (particularly under HIPAA) need to be proactively addressed. Effective deployment of AI requires close collaboration between policymakers, clinicians and technologists to establish standards that ensure equitable and inclusive outcomes.
Brian Kennedy is a renowned biologist, leader in aging research, & director of the Center for Healthy Longevity at the National University of Singapore. In this episode, Brian shares insights from ongoing human aging studies, including clinical trials of rapamycin & how dosing strategies, timing, & exercise may influence outcomes. He presents two key models of aging—one as a linear accumulation of biological decline & the other as an exponential rise in mortality risk—& explains why traditional models of aging fall short. He also explains why most current aging biomarkers lack clinical utility & describes how his team is working to develop a more actionable biological clock. Additional topics include the potential of compounds like alpha-ketoglutarate, urolithin A, & NAD boosters, along with how lifestyle interventions—such as VO2 max training, strength building, & the use of GLP-1 & SGLT2 drugs—may contribute to longer, healthier lives.

However, it really is something to celebrate, not least because the electronic device that you are using to read this article depends on some of the advanced applications of quantum phenomena.
This year was chosen because 2025 marks the centenary of the publication of the first articles on quantum mechanics, also known as quantum physics.
Michael Graziano is a scientist and novelist who is currently a Professor of Psychology and Neuroscience at Princeton University. He’s a best-selling author and has written several books including “Consciousness and the Social Brain”, “Re-thinking Consciousness”, “The Spaces Between Us”, and much more. His scientific research at Graziano Lab focuses on the brain basis of awareness. He has proposed the “attention schema theory” (AST), an explanation of how, and for what adaptive advantage, brains attribute the property of awareness to themselves.
