A saga of HeLa cells

We have been using HeLa cells in my laboratory since 1982, when I arrived at Columbia University Medical Center fresh from postdoctoral work with David Baltimore at MIT. I brought with me a line of HeLa cells and used them for 30 years for our research on viruses. Here is a story of how we lost ... Read More

Top chefs, artisanal food producers, and microbiologists join forces to explore new tastes and textures

Chefs from top-notch restaurants are reaching out to microbiologists, seeking advice that goes beyond traditional food safety or conventional food-processing concerns.
