UCLA scientists reveal how Nipah virus infects cells

...om a Nipah virus outbreak." In the United States, agricultural experts estimate the value of pigs alone in the hog-farming industry at $8.6 billion. The first reported outbreak of Nipah virus in Malaysia occurred between 1998 and 1999, sickening 265 people and killing 105. Spread from bats to pigs to humans, th...

Aquatic plants may hold key to advancing plant disease management

...l mechanisms found in aquatic plants to land-based agricultural systems," said Schmale. Research done on the management of freshwater plant disease has created environmentally sound methods of plant disease control. While plant pathologists typically try to save plants from plant disease, plant pathologists can ...

Tropical Deforestation affects rainfall in the U.S. and around the globe

...pring and summer seasons when water is crucial for agricultural productivity. Deforestation of Central Africa has a similar effect, causing a significant precipitation decrease in the lower U.S Midwest during the spring and summer and in the upper U.S. Midwest in winter and spring.

Birds and bats sow tropical seeds

...he point of the project is to restore diversity to agricultural landscapes," said Howe. "We'll test the proposition that immigration of trees into this tropical landscape, the remnants and forest fragments that still exist in it is dispersal-limited. That is, the seeds don't get there." Howe said most tropical a...

Agricultural antibiotic use contributes to 'super-bugs' in humans

... between animals and humans. The exact effects of agricultural antibiotic use on human health remain uncertain, they say, despite extensive investigation. "But the effects may be unknowable, unprovable, or immeasurable by the empirical standards of experimental biology." Given all of this uncertainty, Smith and ...

From the agricultural point of view, the branching of the root is essential because roots are responsible for helping plants adapt to adverse environmental conditions. A better understanding of capillary root formation will enable the cultivation of crops that absorb wate...

New discovery: If it weren't for this enzyme, decomposing pesticide would take millennia

...use on potato fields in 1946. Common names for the agricultural product are Shell D-D and Telone II. "There is also a possibility, which I consider strong, that this surprising enzyme may have already existed in the bacteria and that it catalyzes another, so-far unidentified reaction that these bacteria require ...
