Researchers have found the mechanism that one bacterium uses to enter the intestinal cells of the body. This bacterium is the most common cause of food-borne illness in the U.S.
The bacterium, Campylobacter jejuni, is contracted from eating raw or undercooked poultry, most often found in chicken, said Nick Negretti, WSU alumnus and postdoctoral research fellow at Vanderbilt University Medical Center.
C. jejuni is similar to salmonella. People infected with it tend to get severe abdominal cramps and can have a fever, Negretti said.
The researchers have discovered many secreted proteins that come from C. jejuni. One of them is called CiaD, which allows the bacterium to get into intestinal cells, said Michael Konkel, professor in the WSU School of Molecular Biosciences.

Pacific Northwest National Laboratory in Richland will be the site of a new $75 million research and development facility where scientists will work to improve storage technologies for the national energy grid. The project is called the Grid Storage Launchpad.
“The Grid Storage Launchpad facility will bring together researchers and industry from around the country to modernize and add flexibility to the power grid, advance storage technologies, and boost use of clean energy,” said Secretary of Energy Jennifer M. Granholm. “Deploying new grid technologies means we can get more renewable power on the system, support a growing fleet of electric vehicles, make our grid more reliable and resilient, and secure our clean energy future.”
The planned facility will include 30 research laboratories, some of which will be testing chambers capable of assessing prototypes and new grid energy storage technologies under real world grid operating conditions. The GSL will include flexible workstations and collaboration spaces, including Fellowship Labs, which will provide dedicated space for researchers to incubate storage technologies originating from the U.S. research and development community.

In February 1992, the drawdown test on the Snake River upstream of Lower Granite Dam also lowered the end of the Clearwater River. The new shallow water depth exposed the remains of massive Holbrook Island in the Clearwater between the Memorial Bridge and the railroad bridge after it was scraped out of existence when the slackwater levees were built in the mid-1970s.

A study of biomass burning aerosols led by University of Wyoming researchers revealed that smoke from wildfires has more of a cooling effect on the atmosphere than computer models assume. The study addresses the impact of wildfires on global climate, and we extensively used the NCAR-Wyoming supercomputer (Cheyenne), says Shane Murphy, a UW associate professor of atmospheric science. Also, the paper used observations from UW and other teams around the world to compare to the climate model results. The main conclusion of the work is that wildfire smoke is more cooling than current models assume.
