Hello Mark,
Medical/Science writers are always in high demand, but .... in Basel. I know of a couple of agencies that were staffing, but in Basel to serve the big pharma companies (it seems that no one writes her own papers....). In the French part, i can remember Nestle research center and the CERN. In Nestle, i know for a fact they have people to do the technical writting for them, but i am not so sure in CERN.
Maybe these 2 sites are of help:

I don't believe your wife will be out of a job for longer.... Has she considered work from home?
Good luck,
Lucy
