- Iowa State researchers developing machinery to harvest corn stalks and leaves
12-11-2006 · EurekAlert!
Iowa State University researchers are developing front and rear attachments that allow a conventional combine to harvest corn stover (the stalks, cobs and leaves) as well as grain. The stover could be the source of plant fiber that feeds the next generation of ethanol plants.

- Circadian clock controls plant growth hormone
08-10-2007 · EurekAlert!
The plant growth hormone auxin is controlled by circadian rhythms within the plant, UC-Davis researchers have found. The discovery explains how plants can time their growth to take advantage of resources such as light and water, and suggests that many other processes may be influenced by circadian rhythms.

- Tiny device enables wide range of study at liquid-liquid interface
12-18-2006 · EurekAlert!
Researchers at Washington University in St. Louis are putting a different kind of "foursome" together in hopes of someday developing smart materials called biomimetics that mimic nature. Amy Shen, Ph.D., assistant professor of Mechanical and Aerospace Engineering, and her Washington University colleague William F. Pickard, Ph.D., senior professor of Electrical and Systems Engineering, are collaborating with a researcher at Washington State University, and one at Indiana University/Purdue University on understanding a plant protein called forisome.

- Muscle stem cells may offer a new treatment option for congestive heart failure
03-25-2007 · EurekAlert!
As a new wave of stem cell research continues, cardiologists are trying to tap into the self-renewing cells' life-saving potential. Scientists have performed the first US controlled, randomized Phase I clinical trial using a three-dimensional guided catheter system to deliver muscular stem cells to the heart. The study was presented today at the American College of Cardiology's Innovation in Intervention: i2 Summit in New Orleans.

- Researchers demonstrate way to control tree height
06-18-2007 · EurekAlert!
Forest scientists at Oregon State University have used genetic modification to successfully manipulate the growth in height of trees, showing that it's possible to create miniature trees that look similar to normal trees -- but after several years of growth may range anywhere from 50 feet tall to a few inches. This is a "proof of concept" that tree height can be readily controlled by genetic engineering techniques.

- New Success in Engineering Plant Oils
03-05-2007 · Brookhaven National Laboratory
Using genetic manipulation to modify the activity of a plant enzyme, researchers at Brookhaven have converted an unsaturated oil in the seeds of a temperate plant to the more saturated kind usually found in tropical plants. The research will be published online by the Proceedings of the National Academy of Sciences (PNAS) the week of March 5, 2007.

- Iowa State scientists demonstrate first use of nanotechnology to enter plant cells
05-16-2007 · EurekAlert!
A team of Iowa State plant scientists and materials chemists are the first to use nanotechnology to penetrate plant cell walls and simultaneously deliver a gene and a chemical that triggers its expression with controlled precision. They modified an ISU proprietary technology-mesoporous silica nanoparticles-to work in plant cells. Their breakthrough creates a powerful new tool for targeted delivery into plant cells. The research was a highlighted article in the May issue of Nature Nanotechnology.

- Protecting US crops from terrorist attack to be discussed at 2007 AAAS Annual Meeting
02-18-2007 · EurekAlert!
A sound and safe agricultural system is critical to national security, but are US crops, a cornerstone of our nation's economy, vulnerable to attack? The latest information on strategies currently in place and what is still needed to keep US crops safe from terrorist attack will be presented by Jacqueline Fletcher, Sarkeys Distinguished Professor of Plant Pathology at Oklahoma State University, during the 2007 American Association for the Advancement of Science (AAAS) Annual Meeting in San Francisco, Calif.

- Making waves: How UCL research could minimize the impact of future tsunami
07-02-2007 · EurekAlert!
A team of experts is preparing to create tsunami in a controlled environment in order to study their effects on buildings and coastlines -- ultimately paving the way for the design of new structures better able to withstand their impact. Ahead of today's Coastal Structures 2007 International Conference, Dr. Tiziana Rossetto, UCL Department of Civil & Environmental Engineering, unveiled plans to develop an innovative new tsunami generator capable of creating scaled-down versions of the devastating waves.
