Experts boost activity of potential therapeutic target in triple-negative breast cancer Nov 30, 2022 8:00 am843 views Less than 20% of diagnosed breast cancers are designated “triple-negative,” meaning that the affected tissues lack three types of receptors often found in other breast cancer types, but TNBCs are often aggressive with a higher risk of recurrence, metastasis and mortality. In a study conducted in TNBC cells and in a mouse model of the disease, researchers found that targeting a specific estrogen receptor that is sometimes present in TNBCs alters the activity of dozens of cancer-related genes and slows the growth and metastasis of these breast cancers. Second year of pandemic deadlier for middle aged than the first, analysis finds Nov 17, 2022 8:30 am1106 views The first two years of the COVID-19 pandemic saw an increase in mortality rates, both from COVID-19 and other causes, but the groups hardest hit shifted between the first and second years, according to an analysis of publicly available data. Both years saw an increase in deaths over the five years preceding the pandemic, even with COVID-19 numbers removed. But while the first year was most deadly for those over age 65, the second year hit middle-aged adults the hardest, University of Illinois Urbana-Champaign researchers found.

North 'plaza' in Cahokia was likely inundated year-round, study finds Jul 21, 2022 8:00 am2590 views 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 Jul 5, 2022 8:00 am1037 views 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 Jul 4, 2022 10:00 am750 views 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. Will renaming carp help control them? Jun 27, 2022 8:30 am1182 views 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. Small molecule transports iron in mice, human cells to treat some forms of anemia Jun 24, 2022 9:00 am869 views A natural small molecule derived from a cypress tree can transport iron in live mice and human cells lacking the protein that normally does the job, easing a buildup of iron in the liver and restoring hemoglobin and red blood cell production, a new study found. Staring at yourself during virtual chats may worsen your mood, research finds Jun 13, 2022 1:00 pm1817 views A new study finds that the more a person stares at themself while talking with a partner in an online chat, the more their mood degrades over the course of the conversation.

SHIELD program a model for effective pandemic management, data show Jun 9, 2022 7:30 am3589 views In the fall of 2020, the University of Illinois Urbana-Champaign welcomed students back for in-person instruction amid the powerful first wave of the COVID-19 pandemic. The university successfully maintained operations throughout the semester – with zero COVID-19-related deaths or hospitalizations in the campus community – thanks to its “SHIELD: Target, Test, Tell” program. In a sweeping report, the team behind the campuswide collaboration details the innovations in modeling, saliva testing and results reporting that helped mitigate the spread of the virus, and shares the data collected and lessons learned through the process. Corn genetic heritage the strongest driver of chemical defenses against munching bugs May 3, 2022 10:30 am1011 views 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 May 2, 2022 9:00 am508 views 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. Study tracks COVID-19 infection dynamics in adults Apr 28, 2022 10:00 am1021 views A team led by scientists at the University of Illinois Urbana-Champaign tracked the rise and fall of SARS-CoV-2 in the saliva and nasal cavities of people newly infected with the virus. The study was the first to follow acute COVID-19 infections over time through repeated sampling and to compare results from different testing methodologies. Machine-learning model can distinguish antibody targets Apr 21, 2022 1:30 pm882 views A new study shows that it is possible to use the genetic sequences of a person’s antibodies to predict what pathogens those antibodies will target. Reported in the journal Immunity, the new approach successfully differentiates between antibodies against influenza and those attacking SARS-CoV-2, the virus that causes COVID-19. New approach enhances muscle recovery in aged mice Apr 13, 2022 8:00 am1364 views Scientists have developed a promising new method to combat the age-related losses in muscle mass that often accompany immobility after injury or illness. Their technique, demonstrated in mice, arrests the process by which muscles begin to deteriorate at the onset of exercise after a period of inactivity. Study: First-pass metabolism of alcohol occurs in women's stomachs Mar 22, 2022 8:45 am1234 views Research led by scientists at the University of Illinois Urbana-Champaign identifies the stomach, not the liver, as the site of alcohol first-pass metabolism in women who had sleeve gastrectomies and control-group peers.
