Marine moss reveals clues to anti-cancer compound
03-08-2007 · EurekAlert!
An Oregon Health & Science University researcher believes a new gene cluster from a bacterium that protects a moss-like marine invertebrate from predators may be key to engineering cancer-fighting drugs. Dr. Margo Haygood has detailed her research team's discovery of the large gene cluster in a bacterium that secretes a bioactive molecule that not only protects the larvae of a bushy marine bryozoan from predatory fish, but also confounds a variety of cancer cell lines.

New UD tissue-engineering research focuses on vocal cords
07-31-2007 · EurekAlert!
Damaged or diseased vocal cords can forever change and even silence the voices we love, from a family member's to a famous personality's. Engineering pliable, new vocal cord tissue to replace scarred, rigid tissue in these petite, yet powerful organs is the goal of a new University of Delaware research project. It is funded by a five-year, $1.8 million grant from the National Institutes of Health's National Institute on Deafness and Other Communication Disorders.

Japanese beetle may help fight hemlock-killing insect
09-10-2007 · EurekAlert!
The eastern hemlock, a tall, long-lived coniferous tree that shelters river and streamside ecosystems throughout the eastern United States and Canada, is in serious danger of extinction because a tiny, non-native insect is literally sucking the life out of it. Entomologists at Virginia Tech are now studying a beetle from Japan that may be a natural predator of Adelges tsugae, or hemlock woolly adelgid.
