Taking Cultured Meat to the Next Level
Article

In a study published in Metabolic Engineering, bovine cells were engineered to endogenously produce phytoene, lycopene and β-carotene. We recently had the pleasure of speaking to Andrew Stout, lead author of the study, to learn how these cells were created and explore some of the benefits of engineering in the abilities to produce additional nutrients.

Single-Cell, "Multi-Omics" Analysis Uncovers a New Stage in Immune Cell Formation
Article

A research team from The Walter and Eliza Hall Institute has adopted a single-cell, multi-omics approach to explore this question, focusing particularly on T and B lymphocyte formation. They discovered a new stage in lymphocyte development, information which the researchers say could "enrich future studies of the immune system". We wanted to know more.
