Enzyme structures illuminate mechanism behind bacteria’s bioremediation prowess

Scientists from the Department of Biochemistry and Department of Chemistry have solved the structure of an enzyme caught in the act of attacking toluene — a chemical derived from wood and oil. The work is important because it provides a glimpse of the mechanics of a process that could be harnessed to help clean up oil spills and create valuable new chemicals.

From rocks in Colorado, evidence of a ‘chaotic solar system’

Plumbing a 90 million-year-old layer cake of sedimentary rock in Colorado, a team of scientists from the University of Wisconsin–Madison and Northwestern University has found evidence confirming a critical theory of how the planets in our solar system behave in their orbits around the sun.

The discovery promises not only a better understanding of the mechanics of the solar system, but also a more precise measuring stick for geologic time.

Important new insights to the influence of poverty on child maltreatment

Decades of studies have established a strong link between poverty and child maltreatment.

But identifying connections is only half the battle; uncovering root causes is a key aim of child maltreatment research. A new set of studies published this week and edited by researchers from the University of Wisconsin-Madison, is the first to try to get at the causal mechanisms behind the economic factors that are strongly associated with child maltreatment, either as a risk factor or an outcome.

GOES-16 offers Earth’s first light in true color

After spending months in space, quietly orbiting the Earth, the next-generation geosynchronous satellite has broken its silence and sent back its first images. On Jan. 23, the National Oceanic and Atmospheric Administration (NOAA) released the GOES-16 “first light” true-color images of Earth in high resolution.

Taken from more than 22,000 miles away, GOES-16 offers rapid and striking imagery of the planet and its weather, giving researchers and a host of users an unprecedented look for weather forecast applications.

Telling the tale of midlife in the United States

MIDUS is a national longitudinal study on aging explicitly focused on midlife, including transitions from young adulthood to midlife, and from midlife into old age. While there is a significant body of research that focuses on early childhood and “the twilight years,” what was missing prior to MIDUS was a thorough, in-depth study of what happens to people during midlife, the longest segment of the life course.
