  • Carver Trust grant to advance molecular studies at Illinois

    CHAMPAIGN, Ill. - Rapidly advancing tools let researchers amass oceans of biological data - so much so that fishing out the meaning is as daunting as climbing a mountain without gear. A new $3.15 million, three-year grant from the Roy J. Carver Charitable Trust, however, will make the University of Illinois at Urbana-Champaign a national leader in its capability to analyze molecular information about cells, officials say.

  • Catalyst combining reactivity and selectivity could speed drug development

    Chemists have long believed that inserting nitrogen – a beneficial ingredient for making many pharmaceuticals and other biologically active molecules – into a carbon-hydrogen bond requires a trade-off between catalyst reactivity and selectivity. But a new manganese-based catalyst developed by University of Illinois chemists has given researchers both in one efficient, lower-cost package.

This is the first example of what the researchers call sympatric speciation in a microorganism.

  • Chill-tolerant hybrid sugarcane also grows at lower temperatures, team finds

    U.S. farmers have long hoped to extend sugarcane’s growing range northward from the Gulf coast, substantially increasing the land available for sugar and biofuels. Several hybrid canes developed in the 1980s have proved hardy in cooler climes, surviving overwinter as far north as Booneville, Arkansas. But until now, no one had tested whether these “miscanes,” as they are called, actually photosynthesize, and thus continue to grow, when the thermometer dips.

    CHAMPAIGN, lll. - They were illiterate farmers, builders and servants, but Maya commoners found a way to record their own history - by burying it within their homes. A new study of the objects embedded in the floors of homes occupied more than 1,000 years ago in central Belize begins to decode their story.

  • Click beetles inspire design of self-righting robots

    Robots perform many tasks that humans can’t or don’t want to perform, getting around on intricately designed wheels and limbs. If they tip over, however, they are rendered almost useless. A team of University of Illinois mechanical engineers and entomologists are looking to click beetles, who can right themselves without the use of their legs, to solve this robotics challenge.

  • Computer animations used in court colored by bias, researchers say

    CHAMPAIGN, Ill. - A courtroom jury views a computer animation of a vehicle accident or heinous crime. Does it help bring a conviction or acquittal?
