California regulators expressed skepticism that Pacific Gas & Electric Corp.’s new leaders have enough professional experience to instill the deep corporate culture of safety they say the company has lacked.

The utility has been blamed for more than a dozen of California’s most destructive wildfires in the past two years.

California’s Santa Anita racetrack will impose new rules to scrutinize horses training on its racetrack and add a director of equine welfare following the deaths of 21 horses since Dec. 26.

The main dirt track and turf courses were in a third day of examination Saturday in an effort to uncover what may have led to the series of catastrophic breakdowns. The racetrack remains closed indefinitely for racing.

Homes in wildfire-prone areas around the U.S. could be built to better withstand blazes without increasing the cost of construction, according to a new report.

The research released Tuesday was sponsored in part by the insurance industry and marks the first attempt to quantify the expenses associated with building residences that meet stringent flame-resistant criteria. Few states have adopted such codes, often citing housing costs, but the new findings suggest fire-plagued communities could curb damage and save lives with minimal effect on home buyers.

The growing pains of shared electric scooter businesses have led one Southern California city to take a wait-and-see approach.

The Ventura City Council voted 5-0 this week night to ban scooters after a company called Bird filed an application to bring them to the city.

Authorities say a man apparently set a California home on fire while using a blowtorch to kill spiders.

KFSN-TV reported 29 firefighters were called to a Fresno housing development Tuesday night to put out a two-alarm blaze.

When it comes to getting help navigating a natural disaster, there's so much technology available, the options are almost overwhelming. What works?

Among the more frightening elements of the world we inhabit is the ever-evolving set of extremist ideologies that give rise to justifications for violence. Terrorism is perhaps the clearest example of such violence, but workplace attacks are also increasingly likely to be ideologically motivated. To prevent or manage the risk of incidents, employers must take a proactive approach to spotting radicalization of all kinds. It is therefore important for them to understand the potential threat of “incel” culture, an emerging extremist ideology rooted in anger at women and driven by a furious sense of entitlement.

Los Angeles County's rail system will be the first in the United States to deploy body scanners that can detect suicide vests and other improvised explosives, transportation officials said Tuesday.

Later this year, the Metropolitan Transportation Authority will deploy several portable scanners that can be moved to any of the system's 93 subway and light-rail stations. The devices will be used in response to terrorism threats, or to scan large crowds at a station near a protest or a sporting event, officials said.

The automobile is a killer. In the U.S., 36,675 people died in traffic accidents in 2014. The year before, 2.3 million people were injured in traffic accidents.

During the past decade, over 438 U.S. municipalities, including 36 of the 50 most populous cities, have employed electronic monitoring programs in order to reduce the number of accidents. Red light camera programs specifically target drivers that run red lights.

There’s an old chestnut about infrastructure that goes, Infrastructure is everything you don’t notice—until it fails. It’s a definition that works for any kind of infrastructure, too: big or small, visible or invisible, bridges and garage doors, electric grids and Wi-Fi routers. Infrastructure is everything you take for granted. And you only notice that you take it for granted when it breaks.

Lately, a lot of things have broken. In two incidents over the past two days, hundreds of people were injured or killed: An elevated-highway bridge collapsed in Genoa, Italy, and a pier gave out in Vigo, Spain, during a music festival. The consequences are harrowing. In Genoa, cars dropped 150 feet to the earth as a span of the bridge fell underneath them. In Vigo, concertgoers were plunged into the sea, piled atop one another, when the boardwalk gave out.
