The new tool, PolyZoom, makes it possible to simultaneously magnify many parts of a graphic without losing sight of the original picture.

Climate change may create price volatility in the corn market

April 23, 2012 12:21 pm | by Rob Jordan, Stanford Woods Institute for the Environment | News | Comments

In a study from Stanford University and Purdue University, researchers have shown for the first time that climate change may force the U.S. corn belt to move north in the next 10 years, escaping devastating heat waves. In turn, this will bring substantial price swings to the corn market, adversely affecting industries like food and biofuels.

Nanocrystal-coated fibers might reduce wasted energy

April 18, 2012 5:17 am | by Emil Venere | News | Comments

Engineers at Purdue University have coated glass fibers with a new thermoelectric material formed by dipping glass fibers in a solution containing nanocrystals of lead telluride and then exposing them to heat in a process called annealing to fuse the crystals together. The resulting material is far less brittle and more effiicient to produce than conventional thermoelectrics.

Engine testing company to open facility in Purdue Research Park
