In the following month, the institute entered an unprecedented busy state.
Weber's German team came with three people: a postdoc specializing in stem cell culture named Hans; an associate professor in electrophysiology named Eva; and a doctoral student in bioinformatics named Lina. They brought two boxes of reagents, a portable electrophysiology recording device, and a complete set of three-dimensional culture protocols established by the Weber laboratory.
Hans was a young man in his early thirties, blond, wearing glasses, and spoke quickly with a heavy Bavarian accent. On his first day in the laboratory, he locked himself in the cell room for six hours and came out to tell Manstein, "The temperature fluctuations in your CO₂ incubator are quite large. I've adjusted it, and now it's stable at 37.2 degrees."
Manstein was taken aback, "You adjusted our incubator?"
