The Brief

With LACMA’s new David Geffen Galleries just steps away, it may be easy to forget that we have the richest Ice Age fossil site on Earth right here with the La Brea Tar Pits.

But the museum and research facilities at the tar pits are also scheduled for a multimillion dollar renovation.

Built in 1977, the George C. Page Museum at the tar pits has a special place in the hearts of Angelenos who’ve ever taken a field trip to see its massive mastodon skeletons or dire wolf skulls. Or have maybe shed a tear at the sculptures of the mammoth family in distress in the Lake Pit out front.

All that stuff is staying, museum educator Kay Lai told LAist, but new interactive exhibits will allow visitors to better understand the science that’s happening in their own backyard.

The transformation

“This museum, as beloved as it is, definitely needs that refresh,” Lai said. “And I’m really excited for the next generation of kids that gets to grow up and make new memories here with this new space.”

Lai said the museum refresh will include a new focus on Zed — the 80% complete Columbian mammoth found here — and other notable animals they’ve unearthed over the decades. The mammoth’s bones will be reassembled and Zed will “stand tall for the first time since the Ice Age,” according to the museum’s website.

“We’re able to focus on the very first saber-toothed cat fossils that we’ve ever discovered ... As well as some of our Ice Age survivors ... like Pebbles the Puma ... Pebbles would have been the ancestor of some of the mountain lions that still live in Los Angeles today, including P-22 that passed away a couple years ago,” Lai said.

Then there’s the fish bowl: you know, the fossil lab with windows where you can watch researchers at work?

An even better fish bowl

“So we’ll still have the fish bowl, but it’s going to be much more interactive and there’ll be much more discussion of what’s going on inside the fossil lab,” said Regan Dunn, assistant deputy director and curator at the new Samuel Oschin Global Center for Ice Age Research.

Dunn explained that the area where they store their collections of fossils and other specimens is getting major updates too.

“Super valuable, millions of specimens, will be in upgraded systems where there’s climate control. There’ll be enclosed cabinets and be under much better maintenance. And also allow for much more research to happen,” she said.

The La Brea Tar Pits are still very much an active paleontological research site. Dunn said any time a hole goes in the ground in the Hancock Park area, a new discovery is made.

With new outdoor classrooms and a 1-kilometer pedestrian pathway that will take visitors past excavation sites, the idea is to make the research going on here more visible to the public.

Your last chance to visit the tar pits before its two-year transformation is July 6.

Nearly 20 years after founding a successful environmental and safety consulting services company, Robin Thorne said she still gets checked for being a Black woman in the construction industry.

“I've had situations where people, they don't even make eye contact, and then the male has to step back to say, 'She's running the show,'" she said.

Thorne runs CTI Environmental, a multi-million dollar company that was contracted by the Army Corps of Engineers to do debris removal after the L.A. fires.

She’s been an engineer for decades and knows fewer than one of four workers in architecture, construction and engineering industries who are women — and much fewer are women of color.

That proportion is low considering 47% of the U.S. labor force are women.

That's why she’s organized a “Women in STEM Signing Day” at Long Beach City College on Saturday, May 30. The event’s meant to create the type of excitement normally associated with young people signing up for college sports teams.

She wants younger women to tap into their drive to succeed

There were far fewer women in these jobs when Thorne was growing up in Philadelphia, but she didn’t let roadblocks, including those in her personal life — like being a single mom on public assistance — stop her.

“When I thought about being an engineer, I didn't think about it being male-dominated. I just knew I wanted to be an engineer,” she said.

She added that some women do give up on similar dreams or fail to find the spark that allows them to see themselves doing these jobs. That’s why Thorne started DemoChicks seven years ago. She wants young women to see her and think “engineer,” as well as connect with women who are already working in these industries.

Mentorship, examples, and money

The organization is called DemoChicks because demolition is one of the jobs that keeps Thorne’s company busy. More women are entering architecture, construction and engineering jobs than before, but the percentage of women in each industry is still low:

15% in engineering
26% in architecture
11% in construction

These are mostly stable jobs with good entry-level wages, jobs such as safety coordinators, project managers, project engineers and construction managers.

Beyond giving teen girls IRL examples of women in construction industry jobs, DemoChicks supports their academic efforts, which often means helping them out meet college expenses. DemoChicks gave out $1,000 scholarships to eight women last year (35 applied).

One of those scholarship recipients in 2024 was Ana Terrazas. She recalled growing up in South L.A., not as a latch key kid, but as a truck cab kid.

 ”My mother… was a truck driver,” Terrazas said, driving belly dump trailers on construction sites. Terrazas would help her mother change tires and lend a hand with any mechanical repairs. Her grandfather was a truck driver too.

“Since then I've always been obsessed with job sites, and also the superintendent, the one that would tell everybody where to go, how to do their job, and organize everything,” Terrazas said.

Two years ago she was working hard to finish her two majors — civil engineering and construction management — to earn her bachelor’s degree from Cal Poly Pomona. She applied for and was awarded a $1,500 scholarship from DemoChicks. That help, she said, had a big effect.

“I didn't have to take as many hours of work to be able to focus more on my studies and also in my internship during that time,” Terrazas said.

The internship, at Swinerton, a nationwide construction company that's more than 100 years old, turned into full time work as a project engineer.

Terrazas paid it forward earlier this year, inviting Thorne and a dozen DemoChicks to a Swinerton work site during Women in Construction Week. She urged the women to tap into their drive to succeed and lean on people like her for help.

“As long as they're driven and this is what they want, there shouldn't be a reason for them to not be able to get a job here,” Terrazas said.

In the face of the nation's highest gas prices, California lawmakers approved a bill to ease restrictions on E85 conversion kits — devices that let conventional gasoline cars run on a cheaper, mostly ethanol fuel blend.

Assembly Bill 2046, dubbed the “Access to Affordable Gas Act” by its author, Assemblymember Rhodesia Ransom, a Stockton Democrat, advanced through the Assembly on a 59-0 vote with no debate or opposition.

The measure is the latest example of Sacramento lawmakers scrambling to respond to gas costs that have soared amid the Iran-Israel war, which has rattled global oil markets and pushed California pump prices above $6 a gallon. It now heads to the California state Senate and would need Gov. Gavin Newsom’s approval before it becomes law.

“Californians consistently pay more at the pump than drivers from other states, and gas prices are once again climbing across the state,” Ransom said on the Assembly floor Thursday. “For commuters and working families, [the proposal] offers a practical way to save money.”

If approved in its current form, the measure would exempt manufacturers of E85 converter kits from an approval process by the state’s primary climate regulator, the California Air Resources Board, which requires companies to demonstrate the devices do not increase a vehicle's emissions. The bill would leave in place a separate federal certification process run by the Environmental Protection Agency.

“Members in Sacramento are looking for ways to try to reduce costs — or appear to reduce costs of driving — and so this is a way to do that,” said Aaron Smith, a UC Berkeley economist and fuels expert.

The converter kits, which cost between $800 to $1,250, according to a legislative analysis of the bill, would let drivers convert their cars to run on both gasoline and E85 fuel.

E85 is a blend of up to 85% ethanol and 15% gasoline; the share of ethanol typically is between 55% and 85%, said Smith, the Berkeley expert.

Jeff Wilkerson, government affairs manager for Pearson Fuels, the largest E85 fuel provider in the state and a bill supporter, said E85 — much of which is made from Midwest corn — is largely insulated from overseas oil shocks that drive California gas prices. The ethanol blend has sold for $2 or more less per gallon than gasoline during recent price spikes.

While E85 is typically priced lower than gasoline and can reduce petroleum dependence and carbon emissions, it delivers 20% to 30% fewer miles per gallon, according to the air board, meaning drivers only save money when E85 is priced at least 20% to 30% below gasoline.

About 1.3 million vehicles in California can currently use the fuel, which is sold at about 640 stations statewide — just 3% of the state’s more than 15,000 fuel pumps, according to the bill analysis.

Ransom said more E85 pumps would be built if the state loosened restrictions and encouraged demand for the fuel blend. She stressed that her bill would present E85 as an alternative.

“For some people, it may not be a wise choice, but at least now it’s going to be a choice,” she said.

Environmentally, the fuel is rated cleaner than regular gasoline by California's Low Carbon Fuel Standard. But that rating has critics. Smith, the Berkeley economist, said the benefits of ethanol are likely overstated. Official numbers likely understate emissions from land use as rising corn demand for ethanol pushes farmers to clear forested land.

The state’s own certification record offers a cautionary tale. Lindsay Buckley, a spokesperson for the board, said the agency has received only five applications from companies for E85 conversion kits since 2008 and that none has cleared the certification process, which is designed to ensure modified vehicles still meet their original emissions standards. Supporters of the proposal argue the board moves slowly and its regulations are burdensome.

But loosening that standard carries its own risk, cautioned Aaron Kurz, senior consultant on the Assembly Transportation Committee, especially now.

As the federal government has stripped scientific expertise from regulatory decisions, he wrote in his analysis, “this committee should consider if the state should cede authority over an inherently scientific process and set a precedent for transferring approval authority to the federal government.”

MOUNTAIN VIEW – Google is changing what it means to Google.

The company this week announced significant changes to its search box — that austere, single-line input field on its homepage that has been the world's most popular entry point into the web for around two-and-a-half decades.

The new version looks similar to the old one-line text box, but it's dynamic, expanding with longer queries. Users can also drop videos, pictures and files into it for what Google calls "multimodal" search.

Behind the scenes, a bigger shift is under way. Google is merging artificial intelligence and traditional web search in a move that Liz Reid, who oversees search at Google, said brings "the best of web and the best of AI together."

Critics say folding AI deeper into search risks further muddying the waters around the provenance of information gleaned from the web and could take agency away from users. A chatbot is likely to return a summary with only a few links to further information, unlike a web search that returns many pages of links.

But the shift is, in some ways, not surprising, given Silicon Valley's hard pivot toward AI, with Google and others investing billions in the technology and refocusing corporate strategies around it.

For about a year, Google has put "AI Overviews" — short summaries — at the top of some search results. "What we've seen with AI Overviews is that people don't want either just an AI or the web. They want a mix of both," said Reid.

She said she's noticed that users have started to ask longer questions, with more natural language, rather than fragments or key words. "They're asking the question that they really have," Reid said.

For Google, that potentially unlocks new understandings of user intentions. "If you start using more natural language, if you're having a conversation, when you've shifted from researching into buying, you've sort of indicated that. And so we can put better ads because we understand what that is," Reid said.

Google is also introducing agentic functionality to search, so that users can ask it to do tasks over time — like search for theater tickets at regular intervals or send shoppers a notification when something goes on sale or conduct a weekly scan of the internet for local events.

Carolina Milanesi, an independent technology analyst, said Google is trying to make its cash cow business — search — richer and more personalized, and it will make shopping easier. But there is a risk that users may have fewer choices about what to click.

"Right now it's: I ask a question, I get a bunch of answers and I feel that I'm in control as to which answer I take, or if I'm looking for something, which product I'm going to end up buying. That is going to be less so going forward," she said.

Milanesi envisions AI-enabled search and agents proposing products to consumers — perhaps even those they have requested — but with less clarity or choice around where it's coming from.

"If you're going to say: 'I want a pair of Jordans, go find them,' you're not necessarily sure what steps have been taken and whether the AI has used a source or a store that was paid for and, therefore, came up in the search results," she said, "or if AI actually went and did their due diligence and picked the best for me as a customer."

Sarah T. Roberts, director of the Center for Critical Internet Inquiry at UCLA, said the algorithmic underpinnings of Google's web search results have long been "by design, inscrutable to end users," and there's more to it than simply the best of the web floating to the top of any given search. Adding AI will only make the system more opaque, she said.

"What's happening now with AI is that that complexity that already existed will be further obfuscated and even more difficult to unpack," she said.

She noted episodes where Google's AI has provided bad results, including advising putting glue in pizza and eating rocks. "Those gaffes shouldn't be forgotten as Google makes this transition," she said.

And critics say that driving more Google users from web searches to interacting with AI will exacerbate the risks of the so-called "Google Zero" scenario, where the growth of AI queries kills off web search and suffocates the internet click economy as we know it. That includes online shops, web advertisers and news organizations that all depend on referred traffic from Google.

While the redesigned box will be the same for all Google users, there are various tricks and tips online for people who want to disable or avoid some AI functions when using Google.

Early every Saturday for the last three and a half years, William Campbell, 61, leaves his Silver Lake home to be at the Angels Flight station for the first ride at 6:45 a.m.

Campbell is one of a team of operators behind the proverbial wheel of the two near-identical funiculars — named Olivet and Sinai — that go up and down a 33% angle slope from Hill Street to Bunker Hill in downtown Los Angeles.

“You’re a part of living history,” said Campbell, who is dressed in an orange and black waistcoat and bow tie, and wears a bowler hat with a monarch butterfly on top. There’s a reason for that, he said mysteriously.

Today, I am the first rider. Soon after, I am joined by a family visiting from Texas.

“I was just looking at a local tourist place, and I just saw this small, cute railway,” said Michael Nguyen, who was alongside his mother and sister. “I was like, oh, this looks interesting. And I saw that you can actually go on it. I was like, OK, that’s pretty dope.”

Masterminded by lawyer, politician and engineer Col. James Ward Eddy, the Angels Flight “hillevator” opened on New Year’s Eve 1901 as a way for people to travel up and down Bunker Hill, which was then the place where the city’s wealthy population lived.

The journey took them down to the streets and stores below and from 1917, Grand Central Market, with the first passengers paying just a penny fare for what was billed as the “shortest railway in America,” traveling just 298 feet.

When he’s not working his weekday full-time day job investigating animal cruelty and abuse, Campbell spends his spare time looking through online newspaper archives for any information about Angels Flight.

Originally located by the 3rd Street Tunnel — at the end of the block from where it is now — the train has been through several changes, as has Bunker Hill itself.

“All the wealthy people moved to Beverly Hills, and Brentwood, and Bel Air, and beyond. And all their wonderful Victorian mansions were turned into boarding houses, and it attracted a lower income, more diverse population, which resulted in blight and crime — at least according to the city,” Campbell said of Bunker Hill's transformation.

City officials authorized Bunker Hill to be all but razed in the 1950s and '60s, and Angels Flight was put into what was promised to be temporary storage for a year or two, despite protests from singer Peggy Lee and others.

The year was 1969. And it took nearly three decades for its return. Angels Flight welcomed passengers again in 1996 to its current location after test runs were made with cases of beer and soft drinks weighing 9,000 pounds. The cable cars were rebuilt exactly as before, but with modern safety requirements, such as Sinai having wheelchair space.

A 2001 accident in which one person died and seven were injured saw another long closure until 2010, and there was a derailment in 2014, which saw another short shuttering. But Angels Flight has been running ever since 2017, save the odd mechanical problem.

Campbell describes himself as a cheerleader for Angels Flight, and you can easily see why. During his shift he pins up a 1904 photo of the city’s landscape taken from an 80-foot-high observation tower at the original location, so people can compare it to the skyscraper skyline of today.

“At one time you could see all the way to Catalina,” he noted.

There is also a display about near-forgotten Bunker Hill folk artist Marcel Cavalla, and Campbell gives away Angels Flight bookmarks, stickers and maps, all of which he researches, designs and prints out of his own pocket.

One of his projects, old advertisements from 1901 to the 1940s, is displayed in the panels above the seats, and was installed a couple of months ago.

There's everything from old Market Basket supermarket ads, to Barbara Stanwyck shilling for Lux toilet soap, to a standard power mower from John Bean manufacturing, to one for the Catalina Carrier Pigeon Service, which operated from 1894 to 1902, taking messages from Avalon to Bunker Hill.

And the monarch butterfly on his hat? That’s related to his Angels Flight “holy grail,” the one question he can’t definitively answer: why were they painted orange and black?

With that, Campbell grabs his binoculars and sees there are passengers waiting for a ride up, so I get into Olivet and wave goodbye as I travel down to Hill Street.
