Fungal Movement. Few scientists are aware of the extraordinary range of movements accomplished by fungi. The speed of these biophysical processes ranges from the slow extension of hyphae accompanying the penetration of plant tissues, to blisteringly fast mechanisms of spore discharge. Current research in the Money lab is concerned with spore discharge in basidiomycete and ascomycete fungi: How do these mechanisms work and how might they have evolved? Experimental approaches include (i) the use of ultra high speed digital video to capture images of spore motion, (ii) the employment of new analytical tools to study the chemical processes that prime these discharge mechanisms, and (iii) mathematical modeling of the launch and subsequent flight of microscopic spores.

Indoor Molds. From first breath to last gasp humans inhale the microscopic spores of fungi, usually to little ill effect. In recent years, however, the spores of indoor molds have acquired a singularly bad reputation. Stories of black molds that plague homes and poison and stupify their inhabitants have swept the nation. Stachybotrys chartarum is a toxin-producing fungus that has been indicted as the worst of all molds. No other fungus produces such a range of toxins in such high concentrations. But despite its unpleasant resume, medical evidence linking Stachybotrys to specific illnesses is sketchy. The way in which people might be exposed to the mycotoxins generated by this fungus is one area of uncertainty, and experiments on conidial dispersal in the Money lab are designed to solve this part of the indoor mold puzzle.
