Goat domestication was a mosaic -- not a singular -- process, with capture from the wild impacting genetic diversity in different regions of the Fertile Crescent. These wild populations have left different genetic legacies in Asian, African and European populations today. Farmers were selecting specific traits in goats such as coat color and production ability as early as 8,000 years ago.
India will need to feed approximately 394 million more people by 2050. Meanwhile, many of its regions are chronically water-stressed, and nutrient deficiencies are widespread -- 30 percent of Indians or more are anemic. But a study published today in Science Advances shares a brighter outlook: replacing some rice with less thirsty crops could dramatically reduce water demand in India, while also improving nutrition.
A multidisciplinary team of experts from the University of Cincinnati determined that the sandy soils of Chaco Canyon were not too salty to grow crops such as maize, beans and squash for the more than 1,200 people who occupied this beautiful but harsh landscape during its most prolific years. The study suggests people of Chaco Canyon largely were self-sufficient.
While current training for food safety and sanitation usually incorporates high-technology presentations, such as videos and slide shows, there is still a need for low-tech approaches, according to Penn State researchers.
A robot developed by the University of Illinois to locate genes for high-yielding, hardy traits in crop plants' DNA was recognized by the best systems paper award at Robotics: Science and Systems, the preeminent robotics conference held last week in Pittsburgh.
Climate change predictions are not taking account of the full range of possible effects of rising carbon dioxide levels, researchers say.
Whether it's buying a car, purchasing a home, or preparing to start a family, consumers are faced with many financial decisions throughout their lives. They turn towards advisers to help manage and guide their finances. But how do consumers decide which planner to trust? A new study from the University of Illinois investigates the value consumers place on financial advisers based on their credentials.
Rice is the third most widely grown cereal grain worldwide, and the bran left over from milling white rice is available in large quantities for livestock feed. Rice bran is high in unsaturated fatty acids, but limited information is available about effects of rice bran on growth performance of growing-finishing pigs and impacts on meat and carcass quality. A new study from the University of Illinois provides this information for the first time.
Roasted barley, when struck by a common laser beam, can illuminate the throat and the gastrointestinal track. The discovery could improve our ability to diagnose swallowing disorders, which affect more than 15 million Americans, as well as gut disorders. What's more, because many human diets already include barley, it could be fast-tracked for medical use.
Bananas are one of the world's most popular fruits. But how they're stored prior to reaching grocery shelves can adversely affect their flavor and smell. Now in a study appearing in ACS' Journal of Agricultural and Food Chemistry, scientists report that cold temperatures suppress the activity of proteins that play a key role in the formation of the banana's distinct aromas. They say this discovery could lead to enhancements of the fruit's fragrance and flavor.
