Nicotinamide adenine dinucleotide, a coenzyme critical for cellular energy metabolism that declines with age. NAD+ precursors like NMN and NR are studied as longevity interventions.

Mechanistic target of rapamycin, a key nutrient-sensing pathway that regulates cell growth and aging. Inhibiting mTOR (e.g., with rapamycin) has shown lifespan extension in multiple organisms.

A class of drugs that selectively eliminate senescent (aged, dysfunctional) cells to reduce inflammation and improve tissue function.

What is Epigenetic clock?

A biomarker based on DNA methylation patterns that estimates biological age, often more predictive of health outcomes than chronological age.

The period of life spent in good health, free from chronic diseases and disability associated with aging.

An immunosuppressant drug that inhibits the mTOR pathway. Research shows rapamycin may extend lifespan and improve age-related health outcomes in multiple species.

What is Biological age?

A measure of how well or poorly your body is functioning relative to your chronological age, assessed through biomarkers such as DNA methylation, telomere length, and blood panels.

What is Caloric restriction?

A dietary regimen that reduces calorie intake without malnutrition. Caloric restriction is one of the most studied interventions shown to extend lifespan across species.

Protective caps at the ends of chromosomes that shorten with each cell division. Telomere length is associated with aging and age-related diseases.

A state in which cells permanently stop dividing but resist death, accumulating with age and secreting inflammatory factors that damage surrounding tissue.

A second-generation epigenetic clock that predicts time to death and is considered one of the most accurate measures of biological aging.

What is Inflammaging?

Chronic, low-grade inflammation that increases with age and contributes to the development of age-related diseases including cardiovascular disease, diabetes, and neurodegeneration.

The large-scale study of proteins in biological systems. In longevity research, proteomics identifies blood protein signatures that predict biological age and disease risk.

What is Yamanaka factors?

A set of four transcription factors (Oct4, Sox2, Klf4, c-Myc) that can reprogram adult cells to a pluripotent state. Partial reprogramming with Yamanaka factors is being explored to reverse cellular aging.

Nicotinamide mononucleotide, a precursor to NAD+ that is widely studied as a supplement to boost cellular energy and combat age-related decline.

A gene-editing technology that allows precise modifications to DNA. In longevity research, CRISPR is used to study and potentially modify genes associated with aging.

Michael Truell’s coding company has quickly ascended to become one of the fastest-growing startups, but it now faces stiff competition from major players like Anthropic and OpenAI. As the landscape of generative AI evolves, investment strategies are becoming more nuanced. Product management expert Kayla Doan emphasized that while generative AI can present compelling opportunities, it is not always the optimal choice for investment, indicating a need for strategic allocation of resources.

This shift in investment philosophy highlights the broader trend of adapting to rapidly changing technologies within the biotech and healthspan sectors. As generative AI continues to influence research and development in longevity science, professionals must remain agile in their approach to funding and innovation.

A key takeaway for longevity researchers and biotech professionals is the importance of evaluating the potential of emerging technologies, like generative AI, against other investment opportunities to maximize impact in the field.
