Ted Talk: The Era of Personal DNA Testing is Here Ted Talk
In his TED Talk, “The era of personal DNA testing is here", biologist Sebastian
Kraves explains how the "personal DNA revolution" is taking genetic analysis out of high-
end laboratories and putting it into the hands of everyday people. He explains how bulky,
expensive DNA equipment has evolved into portable, shoebox-sized analyzers that allow for
rapid testing right on-site. For example, a pig farmer can diagnose swine flu in an hour rather
than waiting weeks for lab results, and a truffle farmer can instantly verify the authenticity of
expensive fungi to avoid being scammed by knockoffs.
Kraves provides evidence of how on-site genetic testing saves lives and expands the
limits of science, such as virologist Ian Goodfellow using portable machines to track Ebola in
Sierra Leone despite extreme heat and humidity. He also highlights the Genes in Space
competition, where a 16-year-old student designed a DNA experiment currently being used by
astronauts on the International Space Station. Kraves concludes that just as computers
transformed how we process information, personal DNA technology will become a fundamental
tool for families and students to explore the living world from their own kitchens.
