    Study tracks waterbird use of Chicago-area wetlands

    A three-year study in northeastern Illinois and northwestern Indiana found that – even at small scales – emergent wetlands or ponds support many wetland bird species. The study also found that, at least in the years surveyed, the level of urbanization had little effect on most of the studied species’ use of such sites, provided the right kinds of habitat were available.

    Cowbird chicks do best with two warbler nest mates – not four, not zero, study finds

    Brown-headed cowbirds are generalist brood parasites, laying their eggs in the nests of many other bird species and letting the host parents raise their young. A new study seeks to understand the strategies cowbird chicks use to survive in prothonotary warbler nests when they hatch with different numbers of warbler nestlings. The study reveals that a cowbird chick does better with two than with four or zero warbler nest mates.

    Study links protecting Indigenous peoples' lands to greater nonhuman primate biodiversity

    By comparing geographic patterns of nonhuman primate biodiversity and human land-use, researchers discovered that areas managed or controlled by Indigenous peoples tend to have significantly more primate biodiversity than nearby regions. They also found that lorises, tarsiers, monkeys and apes whose territories overlap with Indigenous areas are less likely to be classified as vulnerable, threatened or endangered than those living fully outside Indigenous lands.

    Light-activated technique helps bring cell powerhouses back into balance

    Light-activated proteins can help normalize dysfunction within cells and could be used as a treatment for diseases such as cancer or mitochondrial diseases, new research suggests.

    Researchers from the University of Cincinnati, the University of Illinois Urbana-Champaign and the University at Buffalo published the results of their study in the journal Nature Communications. The research centers on the functions of mitochondria, organelles within a cell that act as the cell’s “power plant” and source of energy.

    Study tracks plant pathogens in leafhoppers from natural areas

    Phytoplasmas are bacteria that can invade the vascular tissues of plants, causing many different crop diseases. While most studies of phytoplasmas begin by examining plants showing disease symptoms, a new analysis focuses on the tiny insects that carry the infectious bacteria from plant to plant. By extracting and testing DNA from archival leafhopper specimens collected in natural areas, the study identified new phytoplasma strains and found new associations between leafhoppers and phytoplasmas known to harm crop plants.

    North 'plaza' in Cahokia was likely inundated year-round, study finds

    The ancient North American city of Cahokia had as its focal point a feature now known as Monks Mound, a giant earthwork surrounded on its north, south, east and west by large rectangular open areas. These flat zones, called plazas by archaeologists since the early 1960s, were thought to serve as communal areas that served the many mounds and structures of the city.

    New paleoenvironmental analyses of the north plaza suggest it was almost always underwater, calling into question earlier interpretations of the north plaza’s role in Cahokian society. The study is reported in the journal World Archaeology.

    COVID-19 virus spike protein flexibility improved by human cell's own modifications

    When the coronavirus causing COVID-19 infects human cells, the cell’s protein-processing machinery makes modifications to the spike protein that render it more flexible and mobile, which could increase its ability to infect other cells and to evade antibodies, a new study from the University of Illinois Urbana-Champaign found.

    The researchers created an atomic-level computational model of the spike protein and ran multiple simulations to examine the protein’s dynamics and how the cell’s modifications affected those dynamics. This is the first study to present such a detailed picture of the protein that plays a key role in COVID-19 infection and immunity, the researchers said.

    Study explores coevolution of mammals and their lice

    According to a new study, the first louse to take up residence on a mammalian host likely started out as a parasite of birds. That host-jumping event tens of millions of years ago began the long association between mammals and lice, setting the stage for their coevolution and offering more opportunities for the lice to spread to other mammals.

    Corn genetic heritage the strongest driver of chemical defenses against munching bugs

    Plants release chemical distress signals when under attack from chewing insects. These “911 calls" alert other bugs that dinner or a nice place to lay their eggs is available nearby. If predatory or parasitic insects detect the right signal, they swoop in like saviors to make a meal out of – or lay their eggs in – the bodies of the herbivore insects.

    A new study explores the factors that contribute to corn plants’ chemical signaling capacity, comparing how different corn varieties respond to herbivory in the presence or absence of a soil bacterium known to promote plant health.

    Scientists create viable, reproducing yeast-cyanobacterial hybrids

    Every plant, animal or other nucleus-containing cell also harbors an array of miniature “organs” that perform essential functions for the cell. In plants, for example, organelles called chloroplasts photosynthesize to generate energy for the organism. Because some organelles contain their own DNA and resemble single-celled organisms, scientists have long theorized that the evolution of complex life forms got its start when one cell engulfed another and the two learned to live in harmony – eventually forming, and belonging to, a single entity.

    Vigilantism is an identity for some people, researchers report

    A new study finds that some people routinely monitor the behavior of others and are eager to punish those who violate laws or societal norms, especially when they believe authorities have failed to do so. These self-appointed enforcers willingly embrace the job of keeping order, aren’t particularly concerned about accidentally punishing innocent people, and consider themselves kind and moral actors, the researchers found.

    How do we solve the problem of agricultural nutrient runoff?

    Agricultural runoff from Midwestern farms is a major contributor to a vast “dead zone” in the Gulf of Mexico. Nitrogen, phosphorous and other farm nutrients drain into the Mississippi River, which empties into the Gulf, spurring algae to overpopulate and suffocating other aquatic life. Illinois is a main culprit in this ongoing environmental blight. News Bureau life sciences editor Diana Yates spoke with U. of I. natural resources and environmental sciences researcher Lowell Gentry about possible solutions.

    CRISPR-Cas13 targets proteins causing ALS, Huntington's disease in the mouse nervous system

    A new study by University of Illinois Urbana-Champaign researchers used a targeted CRISPR technique in the central nervous systems of mice to turn off production of mutant proteins that can cause ALS and Huntington’s disease. Rather than the popular DNA-editing CRISPR-Cas9 technique, the new approach uses CRISPR-Cas13, which can target mRNA – the messenger molecule that carries protein blueprints transcribed from DNA. The Illinois team developed Cas13 systems that could target and cut RNAs that code for the proteins that trigger ALS and Huntington’s disease, effectively silencing the genes without disturbing the cell’s DNA.
