In a new paper published in the Proceedings of the National Academy of Sciences, research conducted by UMass Amherst graduate student Evan Thaler, along with professors Isaac Larsen and Qian Yu in the department of geosciences, developed a method using satellite imagery to map areas in agricultural fields in the Corn Belt of the Midwestern U.S. that have no remaining A-horizon soil. The A-horizon is the upper portion of the

Corn belt farmland has lost a third of its carbon-rich soil

 E-Mail More than one-third of the Corn Belt in the Midwest - nearly 30 million acres - has completely lost its carbon-rich topsoil, according to University of Massachusetts Amherst research that indicates the U.S. Department of Agriculture has significantly underestimated the true magnitude of farmland erosion. In a paper published in the Proceedings of the National Academy of Sciences, researchers led by UMass Amherst graduate student Evan Thaler, along with professors Isaac Larsen and Qian Yu in the department of geosciences, developed a method using satellite imagery to map areas in agricultural fields in the Corn Belt of the Midwestern U.S. that have no remaining A-horizon soil. The A-horizon is the upper portion of the soil that is rich in organic matter, which is critical for plant growth because of its water and nutrient retention properties. The researchers then used high-resolution elevation data to extrapolate the satellite measurements across the Corn Belt and the tr

University of Southern California and other leading universities launch joint technology licensing program

Date Time Leading universities launch joint technology licensing program USC has joined a coalition of leading research universities that aims to boost the transfer of researchers’ patented technologies and inventions to companies. All told, 15 universities are members of the limited liability corporation University Technology Licensing Program (UTLP): USC, Brown, Caltech, Columbia, Cornell, Harvard, Illinois, Michigan, Northwestern, Penn, Princeton, SUNY Binghamton, UC Berkeley, UCLA and Yale. UTLP will provide a new marketplace that bundles licensable technologies from multiple institutions so that it is easier for companies to acquire them to expand their portfolio of products. “A technology transfer that connects USC and other leading research universities to industry is critical to solving some of societies biggest challenges, growing the economy and adding jobs, and securing U.S. technological advantage in competitive global markets,” said Jennifer Dyer, executive di
