A Labor Saving Way To Monitor Vast Rangelands
2011-09-28 04:35:02

U.S. Department of Agriculture (USDA) scientists have found that unmanned aerial vehicles (UAVs), a tool used by the military, may be suitable for keeping an eye on changing land-use patterns across vast tracts of western rangeland. Ranchers, government agencies and private land managers often need to survey vast, remote rangelands to see how they are being altered by floods, forest fires or other events. Ground-based surveys can be costly and time-consuming. Satellite imagery is...

2011-09-26 08:28:48

   New cacao types with unique flavors that are distinctly Peruvian have been identified by U.S. Department of Agriculture (USDA) scientists. These new flavors could one day be marketed like wine, by geographical provenance. Agricultural Research Service (ARS) scientists at the agency's Sustainable Perennial Crops Laboratory (SPCL) and Systematic Mycology and Microbiology Laboratory (SMML), both in Beltsville, Md., and Peruvian collaborators found these new cacao plants during...

Digital Panoramas Of Rangelands Could Be Rich Source Of Research Data
2011-09-20 10:32:20

  A scientist at the U.S. Department of Agriculture (USDA) is exploring how rangeland ecologists could use high-resolution digital panoramas to track landscape changes. Agricultural Research Service (ARS) hydraulic engineer Mary Nichols uses a digital camera to create a single high-resolution landscape panorama that users can zoom in on to study individual plants, animals or specific features in the landscape. Nichols works at the ARS Southwest Watershed Research Center in...

When wireworms feast on potatoes, the results aren't pretty: The spuds' surfaces are left punctured, pitted and unappealing. For the past few years, U.S. Department of Agriculture (USDA) scientists and their colleagues have sought a solution in the form of spuds with genetic resistance to the worms, with special attention focused on two wild potatoes from Chile and Bolivia: Solanum berthaultii and S. etuberosum. Previous studies showed that the wild potatoes resisted Colorado potato...

USDA Banning 6 Types Of E. Coli From Ground Beef
2011-09-13 13:17:31

  According to multiple media reports, the U.S. Department of Agriculture (USDA) is planning to add six types of E. coli bacteria to its list of adulterants that are banned from being sold in raw beef. The USDA said it will be focusing on six other strains of E. coli that have been found in food in recent years and have made people sick the same way the O157:H7 strain can. A report by the Wall Street Journal said the new USDA plan was set to take effect in March 2012 after a...


Word of the Day
tesla
  • The unit of magnetic flux density in the International System of Units, equal to the magnitude of the magnetic field vector necessary to produce a force of one newton on a charge of one coulomb moving perpendicular to the direction of the magnetic field vector with a velocity of one meter per second. It is equivalent to one weber per square meter.
This word is named for Nikola Tesla, the inventor, engineer, and futurist.
