What happened

A French researcher whose work was praised by Donald Trump and Dr Mehmet Oz during the Covid-19 pandemic published hundreds of papers with “substantial” ethical and legal concerns, according to a new analysis.

Why it matters

An international team of scientists found concerns in 853 articles published by the Institut Hospitalo-Universitaire Méditerranée Infection, or the IHU, hundreds more than previously flagged by past investigations into work at the large research hospital.

Common ground

Of those, institute founder Didier Raoult was listed as co-author on 758 of them, according to one of the researchers behind the new analysis.

Perspective signals

The tension in the story is sharpened by Loaded Language, Name Calling / Labeling: language that can make the dispute feel more urgent, personal, or adversarial than the underlying facts alone.
