species with possible spatial competitors. She discovered that as soon as certain sponge
species grow over corals, the coral develops necrotic tissue. From this she concluded that the spong...

offers few biological benefits for the surgeon, and proteins can migrate away from the sponge. In contrast, the team at UCLA is developing a carrier that is engineered for UCB activities in the biological environment. "It's the right combination of c...
