Chromatin Immunoprecipitation Reveals DNA-Protein Interactions

Proteins interact with DNA to regulate many vital processes in cells. Nearly 40 years ago, researchers developed a way to map these molecular connections.

The image shows six different panels containing cells. On each panel, the cells are labelled using a different fluorescent dye that highlights features of a specific organelle within the cells.

In urban bathhouses in Germany and the surrounding low countries, bathhouse proprietors, known as baders, provided visitors with basic medical care. To draw blood, baders would scratch the skin before placing a heated cupping glass over the incision to extract blood and purge the body. Other tools associated with baders, including dental forceps and an amputation saw, hint at further services they provided.
