ED CARPENTER is spending a year or two in Washington at the National Science Foundation's Office of Polar Programs. He is still connected to his old lab at State University of Stony Brook.

ANDREY DEMIDOV has moved operations from David Andrews lab in East Anglia, U.K., where he worked on polarization spectroscopy in molecular systems with energy transfer. He is now in the U.S. using femtosecond spectroscopy to study primary processes of excitation energy migration and electron transfer in reaction center of photosystem-II.

DIRK GEERTS defended his Ph.D. thesis last June, entitled Genetic modification of photosynthesis in the cyanobacterium Synechococcus sp. PCC7942: gene expression and protein transport. With the demise of the cyanobacterial group at Utrecht (see below), Dirk has taken a post-doc position in Amsterdam, studying integrins and their role in tumorigenesis. Though happy with his position, he laments that his cultures have the wrong color: now red instead of blue-green. On days off and weekends he still teams up with Hans Matthijs (U. Amsterdam) doing physiology experiments on the phycocyanin production in Synechococcus PCC 7942. This offers some compensation.

MASAHIRO ISHIURA and TAKAO KONDO have both moved from the National Institute of Basic Biology in Okazaki to Nagoya. Both will continue their work on cyanobacterial circadian rhythm.

SVEN JANSON is a new Ph.D., having defended his thesis Cell structure and localizatoin of nitrogenase in some marine and brackish cyanobacteria. For the moment he remains in Birgitta Bergman's laboratory.

BART NELISSEN last July defended his doctoral thesis entitled Phylogenetic study of the cyanobacteria on the basis of 16S RRNA gene sequence analysis (See NEWS). He remains at:

YASUYUKI NEMOTO has returned to Japan, having left University of Miami where he had worked in the laboratory of Akira Mitsui on hydrogen production from cyanobacteria.

GEORGE OWTTRIM has returned to the fold after a post-doc in Switzerland with Cris Kuhlemeier working on translation initiation factors in tobacco, particularly RNA helicase proteins. He now has a faculty position and intends to exploit his expertise with helicase proteins to their study in cyanobacteria.

ERIK SODERBACK has returned to Bergitta Bergman's group after a sojourn in England working on regulation of nitrogen fixation genes in the laboratory of Ray Dixon. He has lost little time in recovering his ardor for symbiotic cyanobacteria.

Utrecht Cyanobacterial Group (1975-1995)

We regret to learn of the passing of the Utrecht cyanobacterial group, which accomplished as much as any group in the development of cyanobacterial molecular genetics. Their pioneering work made possible many of the techniques of gene replacement in cyanobacteria that we take for granted today. The group outlived its founder, Gerard van Arkel, by less than a year -- van Arkel died December 1994, four years after his retirement.

The former affiliates of the group have dispersed as follows: PETER WEISBEEK continues to lead the Section Molecular Genetics, which now focuses solely on plant studies. MIES BORRIAS remains in the Section and will extend her work on gene expression to higher plants. GEERT DE VRIEZE, the senior technician, now works with Ben Scheres on root development. ARNAUD BOVY has left to take a post doc position in Wageningen, where he works to improve several cultured plants, including carnation. DIRK GEERTS also has left, taking a post-doc position in the Netherlands Cancer Institute in pursuit of the processes underlying cell adhesion.
