From the old belief that our health is entirely written in our DNA to groundbreaking discoveries proving that lifestyle and environment act as molecular dimmer switches, the science of health is changing forever. 

Brent unpacks the fascinating field of epigenetics with leading researcher Dr Razia Zakarya, Wendy McCormick Research Fellow from the Epigenetics of Chronic Disease research group at the Woolcock Institute of Medical Research. We explore how prenatal environments, air pollution, and everyday lifestyle choices leave an epigenetic "memory" that impacts long-term health, chronic respiratory conditions like asthma, and how cutting-edge genomic sequencing is helping scientists target these changes before disease develops. 

• The DNA Instruction Manual: How epigenetics functions like a set of dimmer switches, deciding which parts of our genetic code are active without changing the underlying DNA sequence.

• Womb to World: Examining how early-life environmental conditions and air quality during fetal development permanently modify gene regulation.

• The Intergenerational Echo: How early exposures create long-lasting health predispositions well into adulthood.

• Looking Forward: How advanced genomic technologies at the Woolcock Institute of Medical Research are paving the way for targeted therapeutic interventions.

If you want to understand how your environment shapes your biology and future well-being, this is a must-listen.
