Plant pathologists with The American Phytopathological Society (APS) are reporting a significant increase in the occurrence of Phytophthora blight of vine crops, including cucumbers, pumpkins, and squash, in many vegetable-growing regions of the United States. This devastating disease, caused by a soilborne pathogen called Phytophthora capsici, often results in nearly total yield loss.
According to Mohammad Babadoost, a plant pathology professor at the University of Illinois, Phytophthora blight has become one of the most serious threats to production of vine crops, or cucurbits, both in the United States and worldwide. "Recent outbreaks of Phytophthora blight have threatened pumpkin and other cucurbit industries in Illinois, where approximately 90 percent of processing pumpkins produced in the U.S. are grown," said Babadoost. "Because of heavy crop losses, growers often have to abandon their own farms and move into different areas, sometimes traveling more than 50 miles, to find fields not infested with Phytophthora capsici," said Babadoost.
Phytophthora blight can strike cucurbit plants at any stage of growth. The infection usually appears first in low areas of the fields where the soil remains wet for longer periods of time. The pathogen infects seedlings, vines, leaves, and fruit. The disease is usually associated with heavy rainfall, excessive-irrigation, or poorly drained soil. Frequent irrigation increases the incidence of the disease.

Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.
Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
