    Study provides basis to evaluate food subsectors' emissions of three greenhouse gases

    A new, location-specific agricultural greenhouse gas emission study is the first to account for net carbon dioxide, methane and nitrous oxide emissions from all subsectors related to food production and consumption. The work, led by University of Illinois Urbana-Champaign atmospheric sciences professor Atul Jain, could help identify the primary plant- and animal-based food sectors contributing to three major greenhouse gas emissions and allow policymakers to take action to reduce emissions from the top-emitting food commodities at different locations across the globe.

    Is the future of agriculture digital?

    With colleagues at several institutions, University of Illinois Urbana-Champaign crop sciences professor Stephen Moose will lead the development of a National Science Foundation Science and Technology Center for Research on Programmable Plant Systems. With $25 million in newly announced funding, the center will create an Internet of Living Things to learn the intimate biological language of plants and their associated organisms. Moose spoke with News Bureau life sciences editor Diana Yates about this new initiative.

    Less salt, more protein: Researchers address dairy processing's environmental, sustainability issues

    Researchers say the high salt content of whey – the watery part of milk left behind after cheesemaking – helps make it one of the most polluting byproducts in the food processing industry. In a new study, chemists demonstrate the first electrochemical redox desalination process used in the food industry, removing and recycling up to 99% of excess salt from whey while simultaneously refining more than 98% of whey’s valuable protein content.

    Beneficial arthropods find winter sanctuary in uncultivated field edges, study finds

    Many species of ground-dwelling beetles, ladybugs, hoverflies, damsel bugs, spiders and parasitic wasps kill and eat pest species that routinely plague farmers, including aphids and corn rootworm larvae and adults. But the beneficial arthropods that live in or near cropped lands also are susceptible to insecticides and other farming practices that erase biodiversity on the landscape.

    A new study reveals that beneficial arthropods are nearly twice as abundant and diverse in uncultivated field edges in the spring as they are in areas that are cropped – if those field edges are rich in an array of flowers and other broad-leaved plants and not just mowed grass.

    Study: Fluorescent light clarifies relationship between heat stress and crop yield

    Scientists report that it is possible to detect and predict heat damage in crops by measuring the fluorescent light signature of plant leaves experiencing heat stress. If collected via satellite, this fluorescent signal could support widespread monitoring of growth and crop yield under the heat stress of climate change, the researchers say.

    Genomic study reveals evolutionary secrets of banyan tree

    The banyan fig tree Ficus microcarpa is famous for its aerial roots, which sprout from branches and eventually reach the soil. The tree also has a unique relationship with a wasp that has coevolved with it and is the only insect that can pollinate it. In a new study, researchers identify regions in the banyan fig’s genome that promote the development of its unusual aerial roots and enhance its ability to signal its wasp pollinator.

    Study: Integrating satellite and socioeconomic data to improve climate change policy

    Bangladesh is on track to lose all of its forestland in the next 35-40 years, leading to a rise in CO2 emissions and subsequent climate change, researchers said. However, that is just one of the significant land-use changes that the country is experiencing. A new study uses satellite and census data to quantify and unravel how physical and economic factors drive land-use changes. Understanding this relationship can inform climate policy at the national scale in Bangladesh and beyond.

    Cahokia's rise parallels onset of corn agriculture

    Corn cultivation spread from Mesoamerica to what is now the American Southwest by about 4000 B.C., but how and when the crop made it to other parts of North America is still a subject of debate. In a new study, scientists report that corn was not grown in the ancient metropolis of Cahokia until sometime between A.D. 900 and 1000, a relatively late date that corresponds to the start of the city’s rapid expansion.

  • Entomology professor Adam Dolezal and his colleagues found that infection with the Israeli acute paralysis virus increases the likelihood that infected bees are accepted by foreign colonies

    Virus-infected honey bees more likely to gain entrance to healthy hives

    Honey bees that guard hive entrances are twice as likely to allow in trespassers from other hives if the intruders are infected with the Israeli acute paralysis virus, a deadly pathogen of bees, researchers report.

    Their new study, reported in the Proceedings of the National Academy of Sciences, strongly suggests that IAPV infection alters honey bees’ behavior and physiology in ways that boost the virus’s ability to spread, the researchers say.

    A little prairie can rescue honey bees from famine on the farm, study finds

    Scientists placed honey bee hives next to soybean fields in Iowa and tracked how the bees fared over the growing season. To the researchers’ surprise, the bees did well for much of the summer. The colonies thrived and gained weight, building up their honey stores. But in August, the trend reversed. By mid-October, most of the honey was gone and the overwintering brood was malnourished, the team discovered.

  • A new study reveals genetic differences that influence how corn responds to higher concentrations of ground-level ozone.

    Study finds rising ozone a hidden threat to corn

    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.

  • Illinois Sustainable Technology Center researchers Elizabeth Meschewski, left, and Nancy Holm and collaborators developed a systematic study to test the effectiveness of the soil additive biochar and found that it may not be as effective as previously thought.

    Biochar may boost carbon storage, but benefits to germination and growth appear scant

    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. Biochar may boost the agricultural yield of some soils – especially poor quality ones – but there is no consensus on its effectiveness. Researchers tested different soils’ responses to multiple biochar types and were unable to verify their ability to increase plant growth. However, the study did show biochar’s ability to affect soil greenhouse gas emissions.

  • Plant biology professor Evan DeLucia and his colleagues found that hotter conditions expected by midcentury will lead to a need for crop irrigation in the Midwest, a region that relies primarily on rainfall to grow crops.

    A warming Midwest increases likelihood that farmers will need to irrigate

    If current climate and crop-improvement trends continue into the future, Midwestern corn growers who today rely on rainfall to water their crops will need to irrigate their fields, a new study finds. This could draw down aquifers, disrupt streams and rivers, and set up conflicts between agricultural and other human and ecological needs for water, scientists say.
