Mobile sustainability game spurs students to take environmental action

Traversing the University of Wisconsin–Madison campus while consulting iPads and smartphones, the students in Cathy Middlecamp’s introductory environmental studies course could have been mistaken for anyone checking social media en route to class. But for these students, class was already in session. Middlecamp, a professor in the Nelson Institute for Environmental Studies, partnered with the UW Mobile Learning Incubator to have students in Environmental Studies 126 playtest a new mobile game under development that explores sustainability features on the UW–Madison campus.

UW-Madison links with New York museum to collect games and learning data

Leaning over a multitouch table, middle schoolers examine a digital underwater environment, shifting blocks across the screen and building lures to capture computerized fish. While the game introduces engineering principles and logic through an entertaining vehicle, the surface of the table is only half the story.

Citizen scientists provide clarity for lake researchers’ big questions

A massive new study of water clarity trends in Midwestern lakes is sure to make some waves in scientific circles. The study involved nearly a quarter of a million observations in 3,251 lakes spread across eight states, and data dating back seven decades. But it’s where that data came from that’s truly noteworthy. For the report, published online April 30 in the journal PLOS ONE, researchers turned exclusively to citizen scientists.

De-extinction: Will dead species live again?

De-extinction is a recent term that involves bringing back an extinct species using DNA that’s been recovered from preserved material. There are two ways that it can be accomplished: one would be cloning to produce a copy of an extinct individual’s genome. The second way is through genetic engineering to re-create a close approximation of what the extinct species’ genome might have once been. The reality is that it’s no longer science fiction. We’re getting close to being able to revive extinct species from recovered DNA.

Lighting up the lab: Team harnesses light for controlled chemical reaction

When chemist Tehshik Yoon looks out his office window, he sees a source of energy to drive chemical reactions. Plants “learned” to synthesize chemicals with sunlight eons ago; Yoon came to the field a bit more recently. But this week, in the journal Science, he and three collaborators detail a way to use sunlight and two catalysts to create molecules that are difficult to make with conventional techniques — a finding that may eventually have implications for drug making and materials science.
