A recent Washington Post-ABC News poll states that roughly half of registered voters say climate change is either “very important” or “one of the most important issues” in their vote for Congress this year. However, many citizens struggle to understand their place in this global issue. Applied Research Institute senior research scientist Ann-Perry Witmer, also a lecturer in agricultural and biological engineering, spoke with News Bureau physical sciences editor Lois Yoksoulian about a more digestible approach to the climate crisis and encouraged readers to participate in a public panel discussion this week.

Entomology professor Gene Robinson, an international leader in honey bee research, has been elected to the National Academy of Medicine “for pioneering contributions to understanding the roles of genes in social behavior.” Robinson directs the Carl R. Woese Institute for Genomic Biology at the University of Illinois at Urbana-Champaign.

A team of Midwestern climate scientists has released a new report with grim predictions about the impact of climate change on the Great Lakes region. The report foresees a growing trend of wetter winters and springs, with increases in heavy rain events leading to flooding, particularly in urban areas with hard surfaces that cannot absorb the excess water. Rural areas will likely see more erosion, and unpredictable cycles of heat and rainfall could undermine agriculture.

The soybean cyst nematode sucks the nutrients out of soybean roots, causing more than $1 billion in soybean yield losses in the U.S. each year. A new study finds that one type of fungi can cut the nematodes’ reproductive success by more than half.

A report in the journal Science Advances details the grim realities facing a majority of the nonhuman primates in the world – the apes, monkeys, tarsiers, lemurs and lorises inhabiting ever-shrinking forests across the planet. The review is the most comprehensive conducted so far, the researchers say, and the picture it paints is dire.

Four professors at the University of Illinois at Urbana-Champaign have been elected 2018 Fellows of the American Association for the Advancement of Science.

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.

An unusual study that involved bar coding and tracking the behavior of thousands of individual honey bees in six queenless bee hives and analyzing gene expression in their brains offers new insights into how gene regulation contributes to social behavior.

Scott Irwin, the Laurence J. Norton Chair of Agricultural Marketing in the department of agricultural and consumer economics at the University of Illinois Urbana-Champaign, is the author of “Back to the Futures,” a book that’s part personal memoir and part explainer of the futures market.

It may seem off-putting to some, but human waste is full of nutrients that can be recycled into valuable products that could promote agricultural sustainability and better economic independence for some developing countries.

University of Illinois engineers developed a model to calculate the age of nitrogen in corn and soybean fields, which could lead to improved fertilizer application techniques to promote crop growth while reducing leaching.

Gastrointestinal problems are common among endurance athletes, and many of them may be struggling with undiagnosed irritable bowel syndrome, a new study by University of Illinois food scientists suggests.

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.

The 15-millionth volume in the collection of the University Library is a copy of Walter of Henley’s 13th-century work “Hosbondrye,” one of the most influential works on agriculture and land management in the Middle Ages.

The researchers call it the most comprehensive study on the subject to date.

A new UI study shows that tomatoes and broccoli – two vegetables known for their cancer-fighting qualities – are better at shrinking prostate tumors when both are part of the daily diet than when they’re eaten alone.

The nitrate runoff problem, a source of carcinogens and a cause of suffocating algal blooms in U.S. waterways, may not be all gloom and doom. A new study led by the University of Illinois Urbana-Champaign demonstrates an approach for the integrated capture and conversion of nitrate-contaminated waters into valuable ammonia within a single electrochemical cell.

Swapping food stamps for food boxes would mean scrapping 'the most successful government program we have going today,' said U. of I. professor Craig Gundersen

Crop modeling is essential for understanding how to secure the food supply as the planet adapts to climate change. Many current crop models focus on simulating crop growth and yield at the field scale, but lack genetic and physiological data, which may hamper accurate production and environmental impact assessment at larger scales.

The quest to satisfy the sweet tooth without adding to the waistline has a new weapon in its arsenal: a strain of yeast that can metabolize lactose, the sugar in dairy products, into tagatose, a natural sweetener with less than half the calories of table sugar.

Hive genomics – not individual genetic traits – drive aggression in a unique population of gentle Africanized honey bees, a new study reveals. “This is a signal that there may be more to the genetics of behavior as a whole than we’ve been thinking about,” said U. of I. bioinformatics professor Matthew Hudson, a co-author of the study. 

Grocery shopping in person remained extremely common throughout the COVID-19 pandemic, while restaurant dining was more vulnerable to surges in case rates, according to a new study examining how Americans acquired food at various points during the pandemic.

A study of overweight dogs fed a reduced calorie, high-protein, high-fiber diet for 24 weeks found that the dogs’ body composition and inflammatory markers changed over time in ways that parallel the positive changes seen in humans on similar diets. The dogs achieved a healthier weight without losing too much muscle mass, and their serum triglycerides, insulin and inflammatory markers all decreased with weight loss.

Take a fish out of water and its stress hormones will go up. Adrenaline and noradrenaline, the “fight or flight” hormones, peak first, followed more gradually by cortisol. A new study finds that largemouth bass whose cortisol levels rise most after a brief bout of stress are inherently harder to catch by angling.

Scientists have developed and deployed a series of new imaging and machine-learning tools to discover attributes that contribute to water-use efficiency in crop plants during photosynthesis and to reveal the genetic basis of variation in those traits.

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.

A new study co-written by Madhu Khanna, a professor of agricultural and consumer economics at Illinois, found that harvesting wood pellets in the U.S. and exporting them to the EU was more environmentally friendly than burning coal in the EU to generate electricity.

The economic devastation wrought by COVID-19 accounts for an almost 43% increase in food insecurity in the U.S., said Craig Gundersen, the ACES Distinguished Professor in the department of agricultural and consumer economics at the University of Illinois Urbana-Champaign.

Arundo donax, a giant reed that grows in the Mediterranean climate zones of the world, isn’t like other prolific warm-weather grasses, researchers report. This grass, which can grow annually to 6 meters (nearly 20 feet) in height, uses a type of photosynthesis that is more common to crop plants like soybeans, rice and peanuts.

A good estimate of how many college students struggle with food insecurity is a difficult number to pin down, says new research from a team of University of Illinois experts who study food choice issues.

Although nutrition-label users eat roughly the same amount of food as less-discerning diners, the two groups diverge when it comes to the quality of the food they eat, says a new paper co-written by Brenna Ellison, a professor of agriculture and consumer economics at Illinois and an expert in consumer food preferences and behaviors.

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.

The World Food Programme recently warned that the COVID-19 pandemic could double the number of people facing extreme food shortages, bringing the number of those in crisis to about 265 million worldwide. Esther Ngumbi, a professor of entomology and of African American studies at the University of Illinois at Urbana-Champaign who writes and speaks about global food security, spoke with News Bureau life sciences editor Diana Yates about the practices that can help reduce the problem of global food insecurity.

Food waste campaigns are a low-cost way to curb waste at all-you-can-eat dining establishments, but they may need to be combined with other environmental changes to make a difference, says new research co-written by Brenna Ellison, a professor of agricultural and consumer economics at Illinois.

University of Illinois entomology professor and department head May Berenbaum, a member of the National Academy of Sciences and longtime editorial contributor to the Proceedings of the National Academy of Sciences and other journals, has been appointed editor-in-chief of PNAS, effective Jan. 1.

Illinois scientists are helping power plants run more efficiently, designing better, longer-lasting batteries, finding new ways to target cancerous tumors, and developing robots that can aid in construction, in agricultural fields and even inside the human body.

Resistance to multiple herbicides is the new norm for populations of waterhemp, a common agricultural weed. With their herbicide options dwindling and nothing new on the horizon, Illinois growers must be strategic in how they manage waterhemp-infested fields, says a University of Illinois expert on crop weed management.

University of Illinois researchers say they now know how to track and map drug and gene delivery vehicles to evaluate which are most effective at infiltrating cells and getting to their targets, insight that could guide development of new pharmaceutical agents. The researchers described their tracking system and their findings on the most effective delivery vehicles in the journal Nature Communications. 

As far as anyone can tell, the cold-water crayfish Faxonius eupunctus makes its home in a 30-mile stretch of the Eleven Point River and nowhere else in the world. According to a new study, the animal is most abundant in the middle part its range, a rocky expanse in southern Missouri – with up to 35,000 cubic feet of chilly Ozark river water flowing by each second.

Illinois officials this month announced that Asian carp would now be called “copi” in an attempt to make the fish more desirable for eating. Joe Parkos, the director of the Illinois Natural History Survey’s Kaskaskia, Ridge Lake and Sam Parr biological stations in Illinois, spoke with News Bureau life sciences editor Diana Yates about scientific initiatives to study and control carp/copi fish populations and the potential for rebranding to aid those efforts.

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.

The future connection between human waste, sanitation technology and sustainable agriculture is becoming more evident. According to research directed by University of Illinois Urbana-Champaign civil and environmental engineering professor Jeremy Guest, countries could be moving closer to using human waste as fertilizer, closing the loop to more circular, sustainable economies.

CHAMPAIGN, Ill. - Giant Miscanthus (Miscanthus x giganteus), a hybrid grass that can grow 13 feet high, may be a valuable renewable fuel source for the future, researchers at the University of Illinois at Urbana-Champaign say.

Research from U. of I. agricultural economists Peter Goldsmith and Alex Winter-Nelson found that the direct donation of livestock to impoverished communities in rural Africa had numerous positive effects ranging from a reduction in poverty to an increase in gender empowerment.

Designing safe bridges and water systems for low-income communities is not always easy for engineers coming from highly industrialized places. A new discipline called contextual engineering helps engineers think beyond personal values, expectations and definitions of project success when tackling global infrastructure problems.
