Caberettist İdil Baydar, lawyer Seda Başar-Yıldız, who represented relatives of NSU victims, and several left-wing politicians: They all received right-wing extremist threatening letters from the sender NSU 2.0 - a nod to Beate Zschäpe's murdering NSU terrorist cell. Partly two years ago. The authors allegedly have connections to the Hessian police, because the personal information for these threats apparently comes from one of their computers. So far, however, the police have not been able to find the authors of the threatening letters. Martín Steinhagen has observed the case for ZEIT ONLINE. He arranges whether the resignation of police chief Udo Münch really helps in the investigation - and whether, in addition to personal details, police structures also need to be changed.

Today, for many of us, wearing masks in public transport or shops is a matter of course. But in April, leading virologists or Federal Health Minister Jens Spahn (CDU) did not think this was necessary. Quite different in Jena. The city in Thuringia was the first in Germany to impose a mask on its citizens in early April. With success: Today Jena has almost no corona infections. But instead of joy, today there is frustration and allegations against Mayor Thomas Nitzsche (FDP). Anne Hähnig, editor of ZEIT in the East, looked around Jena. She reports why the opponents of the mask are becoming increasingly radical there and why many accuse the mayor of being active.

And otherwise? The "Chuck Norris of Science".
