Some populations of mountain pine beetles now produce two generations of tree-killing offspring annually, dramatically increasing the potential for bugs to kill lodgepole and ponderosa pine trees, CU-Boulder researchers have found.
Because of the extra annual generation of beetles, there could be up to 60 times as many beetles attacking trees in any given year, the study found. And in response to warmer temperatures at high elevations, pine beetles also are better able to survive and attack trees that haven't previously developed defenses.
Rounding out a full day of touring CU-Boulder facilities and meeting with faculty, staff and students, NASA Administrator Charles Bolden spoke to a packed house on the afternoon of April 18, 2014.
Bolden acknowledged the close association CU-Boulder has with the space program, calling the university a “pipeline for talent.”
While you might think a person shaking her phone or tablet from side to side is having issues with the device, she might actually be playing a game that has her mimicking a steering wheel motion as part of a language lesson.
The game Nano Nano for mobile devices, created by two University of Colorado Boulder graduate students, is the first app to incorporate gesturing with language learning.
