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.”
Deborah Jin has won the 2014 Isaac Newton Medal, the highest accolade given by the Institute of Physics. She was cited for her experimental work in laser cooling atoms. This work has led to the practical demonstration of universal laws that upderpin fundamental quantum behavior.
