The drought in California has killed some 60 million trees in the past six years. Scientists are now trying to understand what makes some trees vulnerable and some remarkably resilient. To help them learn, they're using climbers as well as drones.
Older Arizonans working longer
Older Arizonans are staying on the job longer, or returning to the workforce, as the value of retirement plans declines in a struggling economy. The Arizona Department of Administration's Aruna Murthy says that's changing the face of the state's workforce.
"A lot of the jobs, we are hearing this across even anecdotally, that a lot of the jobs that were being done by younger folks are being taken over by the older people now," Murthy said.
Murhty says while state officials do not track demographic data by sector, the annual numbers are clearly trending older, with one in five workers in the state older than 54.
