Siddhartha Mukherjee, a geneticist, explores the revolution of genetics and the ability to alter our genetic code. The podcast discusses the potential to treat diseases with genetic manipulation, as well as the ethical concerns of creating 'transgenic' humans. They also delve into the concept of gene editing technology and its consequences, as well as the role of genetic technologies in disease prevention and the possibility of genetically modifying mosquitoes to combat diseases.

Quick takeaways
Genetics has revolutionized how we think of biology and ourselves, allowing us to read and rewrite our genetic code.
Gene-editing technology like CRISPR holds promise in treating diseases through genetic manipulation, but raises concerns about altering what it means to be human.
The use of genetic technology raises ethical questions about privacy, discrimination, and the need for careful regulation.
Deep dives
The importance of understanding genetics
Understanding genes allows us to make informed decisions about our health and future.
The power and limitations of CRISPR
CRISPR technology has the potential to edit genes and eliminate diseases, but there are still many questions and concerns surrounding its use.
The ethical dilemma of genetic testing
Genetic testing provides valuable information but raises questions about privacy and insurance discrimination.
The potential of genetic technology in medicine
Genetic technology has already revolutionized medicine by enabling the development of vaccines and targeted therapies.
The role of regulation and decision-making
Decisions about genetic interventions should be carefully considered and regulated to ensure ethical and responsible use.
Genetics has revolutionised not just how we think of biology but how we think of ourselves. We are, in the words of one geneticist, the first organism that has ‘learned to read its own instructions’. Now, with the breakthrough of gene-editing technology — whose precision allows us to alter a single letter of DNA — we can now not only decipher but rewrite our genetic code. We may soon be able to treat diseases such as cancer not simply with drugs, but with genetic manipulation. Yet behind this medical revolution lies the prospect of something altogether more worrying. Already, we possess the technology to add to our genetic code at will, and thus create the world’s first generation of ‘transgenic’ humans. As we intervene genetically on ourselves with ever more accuracy, do we risk changing what it means to be human? In a potential quest for the genetically ‘normal’, will we risk annihilating the very diversity and mutations on which evolution depends? These are some of the questions that the Pulitzer...
