  • Genomic study explores evolution of gentle ‘killer bees’ in Puerto Rico

    A genomic study of Puerto Rico’s Africanized honey bees – which are more docile than other so-called “killer bees” – reveals that they retain most of the genetic traits of their African honey bee ancestors, but that a few regions of their DNA have become more like those of European honey bees. According to the researchers, these changes likely contributed to the bees’ rapid evolution toward gentleness in Puerto Rico, a change that occurred within 30 years.

  • Scientists: Expanding Brazilian sugarcane could dent global CO2 emissions

    Vastly expanding sugarcane production in Brazil for conversion to ethanol could reduce current global carbon dioxide emissions by as much as 5.6 percent, researchers report in the journal Nature Climate Change.

  • Illinois sportfish recovery a result of 1972 Clean Water Act, scientists report

    Populations of largemouth bass, bluegill, catfish and other sportfish are at the highest levels recorded in more than a century in the Illinois River, according to a new report. Their dramatic recovery, from populations close to zero near Chicago throughout much of the 20th century, began just after implementation of the Clean Water Act, the researchers say.

  • Some plants grow bigger – and meaner – when clipped, study finds

    Some plants behave like the mythical monster Hydra: Cut off their heads and they grow back, bigger and better than before. A new study finds that these “overcompensators,” as they are called, also augment their defensive chemistry – think plant venom – when they are clipped.

  • Is our flood insurance model broken?

    Craig Lemoine, the director of the Financial Planning Program at the College of ACES, discusses the flood insurance market in light of Hurricane Harvey losses.

  • Should states be in the lottery business?

    A major downside to record-breaking lottery jackpots is that money flows from poorer communities into the hands of one incredibly lucky person, said Craig Lemoine, the director of the Financial Planning Program at the College of ACES.

  • Study links fish stress hormones to whether they take the bait

    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.

  • Study finds parallels between unresponsive honey bees, autism in humans

    Honey bees that consistently fail to respond to obvious social cues share something fundamental with autistic humans, researchers report in a new study. Genes most closely associated with autism spectrum disorders in humans are regulated differently in unresponsive honey bees than in their more responsive nest mates, the study found.

  • Two undergrads improve plant carbon-cycle models

    In the summer of 2012, two undergraduate students tackled a problem that plant ecology experts had overlooked for 30 years. The students demonstrated that different plant species vary in how they take in carbon dioxide and emit water through stomata, the pores in their leaves. The data boosted the accuracy of mathematical models of carbon and water fluxes through plant leaves by 30 to 60 percent.

  • Corn better used as food than biofuel, study finds

    Corn is grown not only for food, it is also an important renewable energy source. Renewable biofuels can come with hidden economic and environmental issues, and the question of whether corn is better utilized as food or as a biofuel has persisted since ethanol came into use. For the first time, researchers at the University of Illinois have quantified and compared these issues in terms of economics of the entire production system to determine if the benefits of biofuel corn outweigh the costs.

  • Genetic study shakes up the elephant family tree

    New research reveals that a species of giant elephant that lived 1.5 million to 100,000 years ago – ranging across Eurasia before it went extinct – is more closely related to today’s African forest elephant than the forest elephant is to its nearest living relative, the African savanna elephant.

  • Paper: Nutrition label readers favor food quality over quantity

    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.

    A new study contradicts decades of thought, research and teaching on the history of corn cultivation in the American Bottom, a floodplain of the Mississippi River in Illinois. The study refutes the notion that Indian corn, or maize, was cultivated in this region hundreds of years before its widespread adoption at about 1000 A.D.

  • Survival of many of the world’s nonhuman primates is in doubt, experts report

    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.

  • Pollinator habitat program spreads bad seeds with the good

    Weed scientists in at least two Midwestern states have been reporting for years that a conservation program meant to provide habitat for pollinating insects is sowing bad seeds – including seeds of the potentially devastating agricultural weed Palmer amaranth – along with the good. Now, researchers at the University of Illinois have traced the weed seeds to at least one source: pollinator habitat seed sold by a company in the Midwest.

  • Links between hunger and health lead to recommendation that doctors screen patients for food insecurity

    Almost 50 million people in the United States are food insecure – that is, they lack access to adequate food because of limited money or other resources. University of Illinois economist Craig Gundersen and University of Kentucky’s James P. Ziliak examined recent research on food insecurity and its association with poor health, and offer suggestions including that doctors screen for hunger.

  • Study: Ground-level ozone reduces maize and soybean yields

    Despite government regulations, ground-level ozone – an odorless gas that forms as polluting nitrogen oxides drift in sunlight across the countryside – continues to threaten crop quality and yield. In a new study, researchers quantify this loss from historical yield data for the first time. They show that over the last 30 years, ozone emissions have reduced soybean and corn yields by 5 percent and 10 percent, respectively.

  • Pineapple genome offers insight into photosynthesis in drought-tolerant plants

    By sequencing its genome, scientists are homing in on the genes and genetic pathways that allow the juicy pineapple plant to thrive in water-limited environments. The new findings, reported in the journal Nature Genetics, also open a new window on the complicated evolutionary history of grasses like sorghum and rice, which share a distant ancestor with pineapple.

  • Study identifies chemical in diet that determines a honey bee’s caste

    A closer look at how honey bee colonies determine which larvae will serve as workers and which will become queens reveals that a plant chemical, p-coumaric acid, plays a key role in the bees’ developmental fate.

  • Chill-tolerant hybrid sugarcane also grows at lower temperatures, team finds

    U.S. farmers have long hoped to extend sugarcane’s growing range northward from the Gulf coast, substantially increasing the land available for sugar and biofuels. Several hybrid canes developed in the 1980s have proved hardy in cooler climes, surviving overwinter as far north as Booneville, Arkansas. But until now, no one had tested whether these “miscanes,” as they are called, actually photosynthesize, and thus continue to grow, when the thermometer dips.

  • Study: Groundwater from aquifers important factor in food security

    CHAMPAIGN, Ill. — Thirsty cities, fields and livestock drink deeply from aquifers, natural sources of groundwater. But a study of three of the most-tapped aquifers in the United States shows that overdrawing from these resources could lead to difficult choices affecting not only domestic food security but also international markets.

  • Study: Crop rotation-resistant rootworms have a lot going on in their guts

    CHAMPAIGN, Ill. — After decades of effort, scientists are finally figuring out how insects develop resistance to environmentally friendly farming practices – such as crop rotation – that are designed to kill them. The researchers say their insights will help develop more sustainable agricultural practices.

  • Plant breeder boosts soybean diversity, develops soybean rust-resistant plant

    CHAMPAIGN, Ill. — It took decades of painstaking work, but research geneticist Ram Singh managed to cross a popular soybean variety (“Dwight” Glycine max) with a related wild perennial plant that grows like a weed in Australia, producing the first fertile soybean plants that are resistant to soybean rust, soybean cyst nematode and other pathogens of soy.
