Although a yearning to surf was what first drove native Tucsonan Edward Glenn to Hawaii, what keeps him going back is his life-long interest in marine agronomy. Now, instead of hanging out in the waves, Glenn spends his time on the leeward side of the island of Molokai, working with the local community on sustainable aquaculture projects for the ancient fishponds that dot the islands south coast.
Rather than growing fish, Glenn, Stephen Nelson and their colleagues are focusing on the edible red seaweed, Gracilaria parvispora. The alga, known as "long ogo" by the Japanese, is eaten by people in Hawaii, Asia and the Pacific and is also a source of agar, a common thickening agent in Japanese cooking. This month the team received a grant to develop new markets for Hawaii long ogo products.
Long ogo was once the most important edible seaweed on Hawaiis reefs. In the past, people would go out to the reef and yank the seaweed off the rocks or even take the whole rock, Glenn says. Ultimately, the reef populations of seaweed declined. People started to grow another species of seaweed in tanks on land, but the replacement just wasnt as good.

Proteins must be folded correctly to fulfill their molecular functions in cells. Molecular assistants called chaperones help proteins exploit their inbuilt folding potential and reach the correct three-dimensional structure. Researchers at the Max Planck Institute of Biochemistry (MPIB) have demonstrated that actin, the most abundant protein in higher developed cells, does not have the inbuilt potential to fold and instead requires special assistance to fold into its active state. The chaperone TRiC uses a previously undescribed mechanism to perform actin folding. The study was recently published in the journal Cell.
Actin is the most abundant protein in highly developed cells and has diverse functions in processes like cell stabilization, cell division and muscle...
