• David Meddings of the World Health Organization was misquoted as saying a fungal infection affecting tsunami survivors could be treated with cheap antibiotics (5 February, p 6). What he actually said was that unlike the fungal infection, the vast majority of wound infections can be treated with cheap antibiotics. Also mucormycosis is the name of the disease. The fungus in this case is called Apophysomyces elegans.
• In “Miracle Weed” (5 February, p 38), we incorrectly said that Martin Schnelle conducted the trial of the oral cannabis preparation Cannador in 2003. Schnelle’s group supplied the preparation, but it was John Zajicek of the University of Plymouth, UK, who led the research.
Feedback’s piece about converting units of measurement (12 February) referred to the units of acceleration as metres per second. That should of course have been metres per second squared.
