    Study tracks COVID-19 infection dynamics in adults

    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

    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

    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.

    Team uses MRI to image epigenetics in the brain

    A multidisciplinary team at the University of Illinois Urbana-Champaign has devised a new approach to 3D imaging that captures DNA methylation, a key epigenetic change associated with learning in the brain. The scientists say their proof-of-concept study in pigs will easily translate to humans, as the new method relies on standard MRI technology and biological markers already in use in human medicine.

    New set of chemical building blocks makes complex 3D molecules in a snap

    A new set of molecular building blocks aims to make complex chemistry as simple and accessible as a toy construction kit. Researchers at the University of Illinois Urbana-Champaign developed a new class of chemical building blocks that simply snap together to form 3D molecules with complex twists and turns, and an automated machine to assemble the blocks like a 3D printer for molecules. This automation could allow chemists and nonchemists alike to develop new pharmaceuticals, materials, diagnostic probes, catalysts, perfumes, sweeteners and more.

  • Study: Telehealth services for the elderly should include caregivers

    Family caregivers are often involved in the day-to-day activities of their older relatives, such as communicating with doctors, helping them navigate the health care system and making decisions that affect their care. When the pandemic hit, forcing health care systems to switch to telehealth visits, many of the caregivers who would have been involved in in-person care were left out of the process, according to a new observational study published in the Annals of Family Medicine.

    Overweight dogs respond well to high-protein, high-fiber diet

    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.

    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.

    Models predict optimal airplane seating for reduced viral transmission

    As airline ticket sales have soared during the holiday season and the omicron variant causes surges of COVID-19 cases, a new University of Illinois Urbana-Champaign study may help passengers and airlines reduce risk of COVID-19 transmission by optimally seating passengers to minimize potential virus spread. Researchers used the most current data on aerosol spread on airplanes to calculate optimal seating assignments for common Boeing aircraft at different capacities.

    Gene mutation leads to epileptic encephalopathy symptoms, neuron death in mice

    Mice with a genetic mutation seen in patients with epileptic encephalopathy, a severe form of congenital epilepsy, exhibit not only the seizure, developmental and behavioral symptoms of the disorder, but also neural degeneration and inflammation in the brain, University of Illinois Urbana-Champaign researchers found in a new study. The findings highlight the mutation as an important part of the disease’s pathology and a potential target for treatment.

    Atomic structure of antifungal drug confirms unusual mechanism, opens door to less-toxic derivatives

    Advanced molecular imaging technology has now mapped the structure of a drug widely used to treat fungal infections but whose workings have mystified researchers and physicians for nearly 70 years. In a new study, researchers at the University of Illinois Urbana-Champaign, the University of Wisconsin, Madison and the National Institutes of Health described in atomistic detail the structure of the drug amphotericin B, a powerful but toxic antifungal agent. Seeing the structure provides illumination in the researchers’ quest to formulate less-toxic AmB derivatives.

    Water disinfection byproduct disrupts reproductive hormones, damages pituitary in female mice

    A byproduct formed during water disinfection disrupts hormones in the brain that regulate the female reproductive cycle in mice and also damages cells in the pituitary gland, a new study from University of Illinois Urbana-Champaign researchers found. The new study’s findings of the chemical’s effects on reproductive regulation in the brain complement previous work that found that it also disrupts function in and causes damage to ovary cells, indicating the chemical could impact the entire reproductive system. The researchers hope that the continued study of these effects can help establish a safe level of exposure to guide future regulations.

    Scientists discover how antibiotics penetrate Gram-negative bacterial cell walls

    Scientists have labored for decades to find antibiotics that work against Gram-negative bacteria, which cause some of the deadliest infections in hospital settings and are most likely to be resistant to treatment with existing antibiotics. In a study reported in the journal Chemical Science, researchers developed a new method to determine how antibiotics with specific chemical properties thread their way through tiny pores in the otherwise impenetrable cell envelopes of Gram-negative bacteria.

    Antibodies from original strain COVID-19 infection don't bind to variants, study finds

    People infected with the original strain of the virus that causes COVID-19 early in the pandemic produced a consistent antibody response, making two main groups of antibodies to bind to the spike protein on the virus’s outer surface. However, those antibodies don’t bind well to newer variants, a new study from the University of Illinois Urbana-Champaign found.

    Study identifies molecule that stimulates muscle-building

    In a randomized control study of 10 healthy young men, researchers compared how consuming the single amino acid leucine or its two-molecule equivalent, dileucine, influenced muscle-building and breakdown. They found that dileucine boosts the metabolic processes that drive muscle growth 42% more than free leucine does.

    Study offers insight into underlying causes of seizure disorder in babies

    Researchers report that infantile spasms, a rare but serious seizure disorder in babies, appear to be the result of a molecular pathway gone awry. In their study of a mouse model of the disorder, the researchers discovered that genetic mutations associated with the disease impair a pathway that is involved in building new synapses in the hippocampus, a brain region essential to learning and memory.
