blog postsStudy finds rising ozone a hidden threat to cornOct 1, 2019 6:00 am1360 views Like atmospheric methane and carbon dioxide, ground-level ozone is on the rise. But ozone, a noxious chemical byproduct of fossil fuel combustion, has received relatively little attention as a potential threat to corn agriculture. A new study begins to address this lapse by exposing a genetically diverse group of corn plants in the field to future ozone levels. The study found that some members of the corn family tree are more susceptible than others to yield losses under high ozone air pollution.Purple martin migration behavior perplexes researchersSep 30, 2019 8:00 am1447 views Purple martins will soon migrate south for their usual wintertime retreat, but this time the birds will be wearing what look like little backpacks, as scientists plan to track their roosting sites along the way. The researchers recently discovered that purple martins are roosting in small forest patches as they migrate from North America to Brazil, an unexpected behavior. The scientists published their findings in the Journal of Field Ornithology. Human waste an asset to economy, environment, study findsJul 8, 2019 8:00 am2448 views Human waste might be an unpleasant public health burden, but scientists at the University of Illinois see sanitation as a valuable facet of global ecosystems and an overlooked source of nutrients, organic material and water.Biochar may boost carbon storage, but benefits to germination and growth appear scantJun 19, 2019 8:15 am721 views Biochar may not be the miracle soil additive that many farmers and researchers hoped it to be, according to a new University of Illinois study.
