Mel,
To my knowledge, there has not been additional research on cyanobacteria biology and management. Research funding continues to decline and with researchers like Dr. Frank Wong and Dr. Lane Tredway moving to industry, it is less likely that much new research is going to be conducted on these incredibly interesting organisms. The up side is that we know how to manage the cyanobacteria - reduce shade, avoid the use of organic fertilizers that stimulate cyanobacteria if cyanobacteria are a problem and treat with chlorothalonil (mancozeb is ok) if cultural practices fail. As mentioned above, some other products might also work.
