Weizmann Institute scientist develops a process that one day may yield a solution to the global wastepaper glut
One wouldn’t expect paper to be a major source of pollution: after all, it’s made from wood, which in nature breaks down into tiny components that re-enter the plant growth cycle. Yet without proper dampness and other conditions that are often missing in garbage dumps, paper fails to decompose for dozens of years. As a result, billions of tons of wastepaper cram the planet’s landfills, creating an enormous environmental problem worldwide.
Prof. Edward Bayer of the Weizmann Institute’s Biological Chemistry Department has developed a process that one day may yield a solution to the global wastepaper glut. Back in 1983, he and Prof. Raphael Lamed of Tel Aviv University discovered the cellulosome, a molecular complex that degrades cellulose, a major component of wood, cotton and other types of plant matter. In subsequent years, Bayer and Lamed elucidated the cellulosome’s architecture and identified its major components.

For the first time, an interdisciplinary team from the University of Basel has succeeded in integrating artificial organelles into the cells of live zebrafish embryos. This innovative approach using artificial organelles as cellular implants offers new potential in treating a range of diseases, as the authors report in an article published in Nature Communications.
