He's been able to trace the assembly of protein filaments that move chromosomes in yeast cells and track the movement of individual protein molecules within those filaments—something thought impossible only a few years ago. Two new resident scientists joined the MBL in 1999. Dr. Paul Colinvaux, an Adjunct Scientist, reconstructs Pleistocene climatic and environmental histories of the continents from the sediments of ancient lakes, particularly those found in the Amazon basin. Research has shown that the lowland Amazon forests persisted through glacial cycles, with some re-assortment of species as temperatures fluctuated from the last glacial maximum to the present. Although Colinvaux's research now is concentrated in the Neotropics, he maintains sites in Alaska and Russia for continued study of the paleoecology of the Arctic. Dr. Ayse Dosemeci came to the MBL in October from the National Institutes of Health as an Adjunct Scientist. She is a neurobiologist who studies synaptic plasticity, a biological phenomenon that may be involved in learning and memory and other central nervous system functions. Summer Research Last summer—as has been the case for more than a century—investigators from around the world came to the Marine Biological Laboratory to do research. As always, the excitement of study, scientific exchange, and discinery was great. The 126 principal investigators came from 12 countries and represented more than 100 institution-- One of the many highlights from last summer's research was the ivf-nt publication of a paper in Nature magazine by Drs. Miuuel Holmgren, Jonathan Wagg. Francisco Bezanilla, Robert Rakowski, Paul De Weer, and David Gadsby. In that paper they describe their latest findings about how a specialized cellular machine, the sodium/potassium exchange pump, works. Because thi
