Locust swarming pheromone identified in step toward curbing plagues

Washington | Reuters — Scientists have identified a chemical compound released by locusts that causes them to swarm, opening the door to possible new ways to prevent these insects from devouring crops vital to human sustenance as they have for millennia. Researchers said on Wednesday they identified the pheromone — that is, a chemical produced […] Read more

Wild bees seen dwindling in main U.S. crop regions

Washington | Reuters — Wild bees, crucial pollinators for many crops, are on the decline in some of the main agricultural regions of the U.S., according to scientists who produced the first national map of bee populations and identified numerous trouble spots. The researchers on Monday cited 139 counties as especially worrisome, with wild bee […] Read more

Rising CO2 levels may cut nutrient levels in crops: study

Washington | Reuters — Rising levels of carbon dioxide (CO2) in the atmosphere may cut the nutritional quality of some of the world’s most important food crops, researchers reported Wednesday after conducting experiments simulating conditions expected by mid-century. The amounts of two important nutrients, zinc and iron, were found to be lower in wheat, rice, […] Read more

Scientists make ethanol without corn or other crops

Washington | Reuters — Scientists said Wednesday they have developed a new way to make liquid ethanol efficiently without using corn or other crops needed in the conventional method for producing the biofuel. The scientists said their process turns carbon monoxide gas into liquid ethanol with the help of an electrode made of a form […] Read more
