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.

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 […]
