A collaboration between researchers at the Salk Institute for Biological Studies and the University of California at Los Angeles captured the genome-wide DNA methylation pattern of the plant Arabidopsis thaliana - the "laboratory rat" of the plant world - in one big sweep.

A NASA-sponsored study shows that by using a new technique, scientists can determine what limits the growth of ocean algae, or phytoplankton, and how this affects Earth's climate.

This false-color image shows a cell from the epidermis of an Arabidopsis thaliana plant; the cell has been marked with fluorescent imaging sensors designed to detect the sugar glucose.Scientists at Carnegie's Department of Plant Biology have made the first real-time observations of sugars in the cells of intact and living plant tissues. With the help of groundbreaking imaging techniques, the group has determined that plants maintain extremely low levels of sugar in their roots--as much as 100,000 times lower than previous estimates. The new technology will enable new studies of sugar metabolism in plants, which will inform the effort to engineer higher crop yields for food and biofuel production.

A former astronaut and researcher at the San Francisco VA Medical Center will be traveling to the Cosmodrome space-launch site at Baikonur, Kazakhstan, this Saturday, Sept. 2, 2006, to prepare a crucial experiment designed to demonstrate how human immune response is suppressed in the weightless environment of space.

A team led by a conservationist from the Bronx Zoo-based Wildlife Conservation Society, working with the Chadian government and the European Union project CURESS near Chad's Zakouma National Park, has discovered 100 slaughtered elephants, most of them missing only their tusks -- a sure sign that poaching is on the upswing just outside of this renowned protected area.

A two-step process appears to regulate cell fate decisions for many types of developing cells, according to researchers from the University of Chicago.

Researchers are touting the use of liquid crystalline polymers (LCP) as a viable tool for use in devices such as the sought-after lab-on-a-chip technology.
