Waging War on Cheatgrass

23m

Guest: Ann Kennedy, Soil Scientist with the USDA-Agricultural Research Service  More than nine million acres burned in wildfires across the US this summer – among the highest on record and making it among the most expensive fire-fighting seasons. Western drought and invasive weeds are largely to blame. How are weeds to blame? Consider cheatgrass – aptly named because it grows so aggressively it cheats other native grasses and flowering plants of any chance for survival.  Cheatgrass has taken over large swaths of the sagebrush country. And the kicker is that it’s not tasty to livestock or wildlife, so it just grows and grows and then it dries into perfect kindling just as peak burn season arrives. If we’re going to get a handle on the wildfires burning larger and hotter every year, we have to get a handle on cheatgrass.

The Smart Grid

19m

Guest: Steven Low, PhD, Professor of Computer Science and Electrical Engineering at the California Institute of Technology  When we talk about energy efficiency and the push toward relying on more renewal sources, there’s a parallel effort you may be less familiar with. It’s the work of bringing our electricity system into the new digital age.  Do you realize the “grid” that links a power plant to the light switches in your home is fundamentally decades-old? And that while you may use an app on your smartphone to control the thermostat in your house, many power companies still have to send an actual person to read the meter and see how much electricity you used last month?  A “Smart Grid” is what experts call a future where our electric utility system has been computerized with sensors and chips.

Open-Source Education

22m

Guest: David Wiley, PhD, Education Fellow at Creative Commons, Adjunct Faculty in Brigham Young University's graduate program in Instructional Psychology and Technology, Co-founder and Chief Academic Officer of Lumen Learning  The average college textbook will run you about 100 bucks – some are much more.  And the reliance on those big heavy, worth-their-weight-in-goal texts hasn’t changed, even as just about everything else in our lives has gone digital. But there is a movement afoot to make open source, digital textbooks the norm in college. Several recent studies find students can learn just as much from the open, digital textbook and get grades that are just as high as their peers using the old-school $100-a-pop textbook.
