Teaching and research, a potent educational mix

November 4, 2014 8:20 am | by Craig Chamberlain, Social Sciences Editor, Univ. of Illinois, Urbana-Champaign | News | Comments

A common perception, especially outside the university classroom, is that teaching and research are two separate domains, with little overlap. That’s not the reality, however, for many Univ. of Illinois faculty. For these faculty members, “there is an active and dynamic link” between the two.

Climate change beliefs more influenced by long-term temperature fluctuations

October 31, 2014 8:14 am | by Phil Ciciora, Business & Law Editor, Univ. of Illinois, Urbana-Champaign | News | Comments

In spite of the broad scientific consensus about its existence, global warming remains a contentious public policy issue. Yet it’s also an issue that requires a public consensus to support policies that might curb or counteract it. According to research, the task of educating the public about climate change might be made easier or more difficult depending on their perception of short-term versus long-term temperature changes.

Rivers flow differently over gravel beds, study finds

October 16, 2014 11:00 am | by Liz Ahlberg, Univ. of Illinois | News | Comments

River beds, where flowing water meets silt, sand and gravel, are critical ecological zones. Yet how water flows in a river with a gravel bed is very different from the traditional model of a sandy river bed, according to a new study that compares their fluid dynamics. The findings establish new parameters for river modeling that better represent reality, with implications for field researchers and water resource managers.

Muscle-powered bio-bots walk on command

July 2, 2014 9:28 am | News | Comments

Engineers at the Univ. of Illinois at Urbana-Champaign have demonstrated a class of walking “bio-bots” powered by muscle cells and controlled with electrical pulses, giving researchers unprecedented command over their function. The design is inspired by the muscle-tendon-bone complex found in nature. They have a backbone of 3-D printed hydrogel, strong enough to give the bio-bot structure but flexible enough to bend like a joint.
