Novel ultrafast laser detection of cancer cells also may improve understanding of stem cells

To investigate tumors, pathologists currently rely on labor-intensive microscopic examination, using century-old cell-staining methods that can take days to complete and may give false readings. A lightning-fast laser technique, led by Sandia National Laboratories researcher Paul Gour...

What's really making you sick? Plant pathologists offer the science behind Sick Building Syndrome

Also working on the project is Dr. Alfredo Herrera-Estrella, from the Center for Research and Advanced Studies in Mexico. "There's both pharmaceutical and agricul...

Genome study of beneficial microbe may help boost plant health

...essed two major cotton diseases. Since then, plant pathologists around the world have used this strain as a laboratory model to study beneficial microbes. Paulsen says the P. fluorescens project also pioneered a new methodology. This novel approach relies on the analysis of repeated regions of the DNA sequence t...

Plant pathologists evaluate eco-friendly alternatives to methyl bromide

...gricultural production areas of Florida, say plant pathologists with USDA's Agricultural Research Service. In 1987, the Parties to the Montreal Protocol called for the phase-out of methyl bromide, a soil fumigant used to control soilborne fungi, nematodes, and weeds of more than 100 crops worldwide. The phase ou...

Vineyard weeds found to host Pierce's disease of grapes

...s of Pierce's disease in central California, plant pathologists studied 29 weed species commonly found in California's San Joaquin Valley to see if the bacterium could survive on the weeds. Perennials and known feeding and breeding hosts of the glassy-winged sharpshooter were tested first, then plants particularl...

Aquatic plants may hold key to advancing plant disease management

"The use of plant pathogens to suppress weeds is considered as one of the alternative weed control options for areas...

Single molecule extends fat mice lives by reversing gene pathways associated with disease in obese

...ice. Organ Protection: Heart and Liver Three pathologists examined heart tissue from the SD, HC, and HCR mice, and while not knowing which organ belonged to which mouse group, they looked for subtle changes in the abundance of fatty lesions, degeneration and inflammation. On a relative scale of 0-4, the as...
