Biologist finds cell wall construction pathway

Photo courtesy USDAA WUSTL biologist has advanced the understanding of plant cell walls, which are crucial to plants such as cotton, which needs the cell wall to impart elasticity in cotton fibers.Wood with altered properties and cheaper ethanol through more efficient production are two possibilities as a result of a find by a biologist at Washington University in St. Louis. Erik Nielsen, Ph.D., Washington University biologist , has made a discovery published in a recent edition of The Journal of Cell Biology that sheds new light on how some types of complex sugars in plants are directed to the construction of cell walls.

Triple threat polymer captures and releases

Wooley and lab members examine polymer samples.A chemist at Washington University in St. Louis has developed a remarkable nanostructured material that can repel pests, sweeten the air, and some day might even be used as a timed drug delivery system — as a nasal spray, for instance. Karen L. Wooley, Ph.D., Washington University James S. McDonnell Distinguished University Professor in Arts & Sciences, has taken the same materials that she developed more than four years ago as marine “antifouling” coatings that inhibit marine organisms such as barnacles from attaching to the hull of ships to now capture fragrance molecules and release them at room temperature.
