Back in 2008 the surgeon Paolo Macchiarini stunned everyone when he carried out the world鈥檚 first tissue-engineered whole organ transplant and saved a woman鈥檚 life with a windpipe transplant. When he followed this up by implanting the first artificial trachea into a patient at the Karolinska Institute in Stockholm in 2011, this was celebrated as a huge medical breakthrough. Since then, the surgery has been performed on seven other patients there, but today, six of these eight patients are now dead. The management of the Karolinska Institute is deeply implicated in the case, which is rapidly growing into a veritable research scandal. Both the secretary-general of the Nobel Committee and the head of the Karolinska institute have now resigned. Christine Westerhaus reports from Sweden.

It is endemic in West Africa, but the World Health Organisation is now scaling up an emergency response team in Benin to try to stop it spreading further. Claudia speaks to Dr Pierre Mpele, tropical disease specialist and the WHO鈥檚 country representative in Benin, just after he attends an emergency planning meeting with the ministry of health.
