  • University of Illinois Beckman Institute postdoctoral researcher Agnieszka Burzynska and her colleagues found that physical activity and sedentary behavior are each associated with specific differences in brain white matter integrity.

    Like everything else in the body, the white-matter fibers that allow communication between brain regions also decline with age. In a new study, researchers found a strong association between the structural integrity of these white-matter tracts and an older person’s level of daily activity – not just the degree to which he or she engaged in moderate or vigorous exercise, but also whether the person was sedentary the rest of the time.
  • Topography of a red blood cell as measured by the SLIM optical technique. Though the cell keeps its shape as it ages, the membrane becomes less flexible.

    It may look like fresh blood and flow like fresh blood, but the longer blood is stored, the less it can carry oxygen into the tiny microcapillaries of the body, says a new study from University of Illinois researchers.
  • Andrew Greenlee, a professor of urban and regional planning, is co-leading a project that re-examines how communities near polluted waterways cope with environmental disruptions.

    There’s no such thing as a good place to have a natural disaster, nor has there ever been an appropriate site to release toxic pollutants. But scientists have long recognized that some areas can handle such catastrophes better than others. As early as the 1970s, they used socioeconomic data from the U.S. Census to develop a tool called the Social Vulnerability Index, known as SoVI, to gauge the likely resilience of different communities.
  • University of Illinois plant biology professor Evan DeLucia and his colleagues found that land plants have the capacity to produce much more biomass than previously estimated.

    A new analysis suggests the planet can produce much more land-plant biomass – the total material in leaves, stems, roots, fruits, grains and other terrestrial plant parts – than previously thought.
  • Professor Paul Braun and graduate student Chunjie Zhang developed a continuous glucose-monitoring system that changes color when glucose levels rise.

    University of Illinois engineers are bringing a touch of color to glucose monitoring. The researchers developed a new continuous glucose monitoring material that changes color as glucose levels fluctuate, and the wavelength shift is so precise that doctors and patients may be able to use it for automatic insulin dosing - something not possible using current point measurements like test strips.
  • Kinesiology and community health professor Charles Hillman (right), postdoctoral researcher Laura Chaddock-Heyman and their colleagues found that physically fit children had more compact white-matter tracts in the brain than children who were less fit.

    A new study of 9- and 10-year-olds finds that those who are more aerobically fit have more fibrous and compact white-matter tracts in the brain than their peers who are less fit. “White matter” describes the bundles of axons that carry nerve signals from one brain region to another. More compact white matter is associated with faster and more efficient nerve activity.
