New research shows how cooperation among bacterial species allows them to thrive as a community. After studying 15 kefir samples, the researchers discovered to their surprise that the dominant species of Lactobacillus bacteria found in kefir grains cannot survive on their own in milk, the other key ingredient in kefir. One grain to bind them all. Consumption of kefir originally became popular in Eastern Europe, Israel, and areas in and around Russia. To make kefir, you need kefir grains.

Binding of transcription factors measured on individual DNA molecules in living cells. An important question in the field of gene regulation is how a limited set of transcription factors interpret the same genome in different ways to create over cell types found in our bodies, all of which are defined by the expression of a unique set of genes. To achieve this, transcription factors have evolved cooperative mechanisms to enable precise control of gene expression. In a new study, members of the Krebs group in the Genome Biology Unit at EMBL Heidelberg have developed a method to directly visualise how transcription factors co-occupy DNA in living cells, and have used it to better understand their cooperativity mechanisms. Transcription factors are proteins that bind to specific regulatory DNA sequences to control which genes are turned on or off.
