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 […]
Study identifies best bioenergy crops for sustainable aviation fuels by U.S. region, policy goals
CHAMPAIGN, Ill. — Researchers analyzed the financial and environmental costs and benefits of four biofuels crops used to produce sustainable aviation fuels in the U.S. They found that each feedstock — corn stover, energy sorghum, miscanthus or switchgrass — performed best in a specific region of the rainfed United States. Their study will help growers […]
Light targets cells for death and triggers immune response with laser precision
CHAMPAIGN, Ill. — A new method of precisely targeting troublesome cells for death using light could unlock new understanding of and treatments for cancer and inflammatory diseases, University of Illinois Urbana-Champaign researchers report. Inflammatory cell death, knows as necroptosis, is an important regulatory tool in the body’s arsenal against disease. However, in some diseases, the […]
From ‘CyberSlug’ to ‘CyberOctopus’: New AI explores, remembers, seeks novelty, overcomes obstacles
CHAMPAIGN, Ill. — By giving artificial intelligence simple associative learning rules based on the brain circuits that allow a sea slug to forage — and augmenting it with better episodic memory, like that of an octopus — scientists have built an AI that can navigate new environments, seek rewards, map landmarks and overcome obstacles. Reported […]
A heart of stone: Study defines the process of and defenses against cardiac valve calcification
CHAMPAIGN, Ill. — The human body has sophisticated defenses against the deposition of calcium minerals that stiffen heart tissues, researchers at the University of Illinois Urbana-Champaign and collaborators at UCLA Health and the University of Texas at Austin found in a new study that provides the first detailed, step-by-step documentation of how calcification progresses. “Heart […]
Study links neighborhood violence, lung cancer progression
CHAMPAIGN, Ill. — Scientists have identified a potential driver of aggressive lung cancer tumors in patients who live in areas with high levels of violent crime. Their study found that stress responses differ between those living in neighborhoods with higher and lower levels of violent crime, and between cancerous and healthy tissues in the same […]
