Governor Jerry Brown has signed a bill that will help build out an earthquake early warning system for California. Once it’s up and running, the system will detect the early stages of a quake and transmit a warning to people’s phones and radios. Mark Ghilarducci with the California Office of Emergency Services says it’s a big step.

Ghilarducci: "Technology to be able to sense the time that the energy gets released before the shaking occurs and be able to put that in a warning is very, very significant."

This week on Valley Edition we hear how law enforcement agencies are helping their officers and deputies cope with the mental strain of the job. We also learn why activity tracking software is helping elephants at the Fresno Chaffee Zoo and across the country attain better health and welfare. Later in the show we talk local political races in Fresno and Bakersfield with Nicole Parra and Jim Verros; plus learn about a new book on the history of Kerman from Paul Betancourt.

Fresno Chaffee Zoo

Fitness tracking is all the rage right now. If you want to, you can monitor your heart rate, count your footsteps and calories burned, and even monitor your sleep patterns, all using devices that can fit around your wrist or in your pocket. But that's if you’re a human. Kerry Klein takes us to the Fresno Chaffee Zoo, where fitness tracking is moving to a whole new level.

Commentary: Sexism In Science Is No Funny Joke

A controversy has erupted over an attempted joke by a Nobel prize winning scientist at the 2015 World Conference of Science Journalists held in South Korea last June. It turns out that Science, like the rest of society, has a problem of sexism. In this segment of The Moral Is, Fresno State biology professor Dr. Madhusudan Katti confronts the pervasive everyday sexism in science and challenges the institutions of science to address the structural barriers and cultural climate that keep women out of science.

Scientists Discover What Makes Lake Tahoe Blue

Scientists have long thought that the blueness of Lake Tahoe was due to the lake’s clarity. But as Amy Quinton reports from Sacramento, a new study shows that algae plays an important role.

For the past three years, UC Davis researchers have been measuring the degree of blueness in Lake Tahoe using a NASA research buoy. They compared those results with the lake’s clarity and found something surprising. 

Schadlow: “Clarity and blueness are controlled by very different things.”

Talk to most education leaders about the biggest challenges and opportunities in America’s public schools and the issue of so called STEM courses is sure to come up. It’s a fancy acronym for Science, Technology, Engineering and Math. According to the US Department of Education, job growth in STEM fields is projected to outpace the rest of the economy, in some areas like software and biomedicine, by more than double.

President Obama says STEM is a big education priority, in a speech to education leaders in 2010:

NASA Spacecraft Will Help California Address Drought and Floods

Scientists may soon have a more accurate way to predict the extent and severity of droughts, floods and even the amount of food California can produce. As Amy Quinton reports from Sacramento, a NASA spacecraft getting set to launch will measure soil moisture, one of the most important components of the earth’s water cycle.


A new set of satellite images released by NASA shows the dramatic loss of water storage in the Central Valley due to California's long term drought. According to research by NASA's Gravity Recovery and Climate Experiment Team, the Sacramento and San Joaquin River basins together lost 12 million acre feet a year between 2011 and 2014, largely due to agricultural groundwater pumping.

This week on Valley Edition we explore Fresno's Fulton Mall fifty years after its opening. FM89's Joe Moore takes a look at how the once innovative and bustling outdoor mall transformed over the years. The documentary style piece is filled with the memories of those who shopped there, the minds behind the mall and those who still visit the mall today.

New research this week questions the connection between air pollution and asthma.

In 2011, a study by the San Joaquin Valley Air Pollution Control District established a link between asthma-related ER visits and levels of PM2.5, or fine particulate matter in valley air.  But after a follow-up to that study, the Air District now reports that for a number of years, asthma-related ER visits increased even as PM2.5 levels dropped.

David Lighthall, health science advisor to the Air District, says the findings should not be interpreted as black and white.
