Scientists at UC Santa Barbara have created a remarkable new material that works like a “rechargeable solar battery,” storing sunlight inside tiny molecules and releasing it later as heat — even long after the sun goes down. Inspired by reversible changes found in DNA and
How did the ethanol boom of the 2000s impact farm values in the Midwest?
The U.S. ethanol industry experienced its first major "boom" in the early 2000s, thanks to changes in U.S. energy policies—particularly biofuel mandates—along with the surging crude oil prices and the phaseout of a fuel additive, methyl tert-butyl ether (MTBE). In response,
