Genomic study identifies human, animal hair in ‘man-eater’ lions’ teeth
CHAMPAIGN, Ill. — Hairs extracted from the broken teeth of two 19th century “man-eater” lions finds human, animal DNA.

Study: Good nutrition boosts honey bee resilience against pesticides, viruses
CHAMPAIGN, Ill. — In a new study, researchers at the University of Illinois Urbana-Champaign tackled a thorny problem: How do nutritional stress, viral infections and exposure to pesticides together influence honey bee survival? By looking at all three stressors together, the scientists found that good nutrition enhances honey bee resilience against the other threats.

Report: Conscientiousness, not willpower, is a reliable predictor of success
CHAMPAIGN, Ill. — According to two psychologists, the field of psychological science has a problem with the concept of self-control. It has named self-control both a “trait” — a key facet of personality involving attributes like conscientiousness, grit and the ability to tolerate delayed gratification — and a “state,” a fleeting condition that can best […]

Breaking open the AI black box, team finds key chemistry for solar energy and beyond
CHAMPAIGN, Ill. — Artificial intelligence is a powerful tool for researchers, but with a significant limitation: The inability to explain how it came to its decisions, a problem known as the “AI black box.” By combining AI with automated chemical synthesis and experimental validation, an interdisciplinary team of researchers at the University of Illinois Urbana-Champaign […]

NSF funds new iBioFoundry at Illinois
CHAMPAIGN, Ill. — A newly funded U.S. National Science Foundation iBioFoundry at the University of Illinois Urbana-Champaign will build on more than a decade of research at the U. of I. to integrate synthetic biology, laboratory automation and artificial intelligence to advance protein and cellular engineering. This is one of five new biofoundries to be […]

Scientists use evolution to bioengineer new pathways to sustainable energy, pharmaceuticals
CHAMPAIGN, Ill. — Using evolution as a guiding principle, researchers have successfully engineered bacteria-yeast hybrids to perform photosynthetic carbon assimilation, generate cellular energy and support yeast growth without traditional carbon feedstocks like glucose or glycerol. By engineering photosynthetic cyanobacteria to live symbiotically inside yeast cells, the bacteria-yeast hybrids can produce important hydrocarbons, paving new biotechnical […]

Study tracks decades of extreme heat, cold in Upper Midwest
CHAMPAIGN, Ill. — Researchers analyzed meteorological data from nine Upper Midwest states from 1979-2021, tracking trends in extreme heat and cold over every 4-kilometer square of that territory. They found striking regional differences in the extremes. Many parts of the Upper Midwest experienced significant upticks in the number of extreme heat days over the 40 […]

Weight-loss success depends on eating more protein, fiber while limiting calories, study says
CHAMPAIGN, Ill. — Participants on a self-directed dietary education program who had the greatest success at losing weight across a 25-month period consumed greater amounts of protein and fiber, a study found. Personalization and flexibility also were key in creating plans that dieters could adhere to over time. At the one-year mark, successful dieters (41% […]

How do people use self-censorship to avoid having their content suppressed on sites like TikTok?
Anthropology professor Kendra Calhoun studies the creative language people use on social media platforms to fool algorithms that may incorrectly categorize content as “inappropriate” or “offensive.” Calhoun spoke with News Bureau life sciences editor Diana Yates about this phenomenon, which she calls “linguistic self-censorship.” In a recent report, you and your coauthor, Alexia Fawcett of the University of […]

PFAS found in nearly all fish tested from four northern Illinois rivers
CHAMPAIGN, Ill. — Scientists tested nine fish species from four northern Illinois rivers for contamination with per- or polyfluoroalkyl substances, synthetic chemicals found in numerous industrial and commercial products and known to be harmful to human health. They found fish contaminated with PFAS in every one of their 15 test sites. Elevated levels of PFOS, […]

Study: Fear of falling, fall-related injuries haunt full-time wheelchair, motorized scooter users
CHAMPAIGN, Ill. — Many studies have focused on falls among people who are ambulatory and have conditions like multiple sclerosis or Parkinson’s disease, but research to address falls among those who rely on wheelchairs or motorized scooters is rare, scientists report in a new study. The researchers found that full-time wheelchair or motorized-scooter users also […]
