The Brief

The very first layers of soil were dropped onto the Wallis Annenberg Wildlife Crossing on Monday morning, marking another major milestone for what will become the world’s largest bridge of its kind.

Wildlife advocates, Caltrans officials and project partners hiked to the top of the construction site in Agoura Hills to throw handfuls of soil on the soon-to-be wildlife habitat over the busy 101 Freeway.

Beth Pratt, California regional executive director for the National Wildlife Federation and leader of the Save LA Cougars campaign, told LAist that it’s not just any dirt — it’s the crossing’s first real piece of nature.

“ It wasn't just a bag of soil you bought from Home Depot. [It] had to be cured and meticulously prepared,” Pratt said. “This habitat on top is a result of a lot of design, engineering and planning, and it's happening!”

About the milestone

The soil is a critical piece of the puzzle.

Scientists, biologists, engineers and mycologists took a lot of time and effort to make sure it’s appropriate for the crossing itself, the habitat and the plants that’ll soon spring from the structure, according to Robert Rock, president and chief executive of Rock Design Associates.

“ All the way down to the design for the soil biology, and working with our mycologist to figure out where we're harvesting the native mycorrhizal fungi from,” Rock told LAist. “We're designing all the way from those microbial components all the way up to the apex predator.”

The soil material, made up partly of compost, branches and leaf litter, is comparable to what makes up the green sloping hills on either side of the busy freeway.

It’ll take roughly 6,000 cubic yards to cover the entire crossing, which crews will continue placing over the next few weeks.

“ We finally have that living layer. ... After all of the time and energy that's been put into construction, to see this going in is a really special moment,” Rock said.

What’s next for the wildlife crossing

After all the soil is set, about 5,000 native plants will be placed on top of the structure to help make up the nearly one acre wildlife habitat.

A plant nursery, which was created for the project and is located on land donated by the Mountains Recreation and Conservation Authority, has collected more than a million seeds over the past three years. They include dozens of distinct species from within a five-mile radius of the crossing in the Santa Monica Mountains.

“That degree of, you know, genetic sensitivity to the place where we're working is something that is unique,” Rock said.

The nursery staff have also been growing California buckwheat, several types of sage, toyon and other plant and tree species for future efforts.

Planting is expected to start in May.

With millions of pounds of concrete poured, the structure itself is almost done, Pratt said. That includes the sound barriers, which essentially silences the 10 lanes of rushing traffic on one of the busiest freeways in the country down below.

“Three hundred [thousand] to 400,000 cars a day — so we have to … almost trick [the animals] into thinking they're not on the freeway, “ Pratt said. “And sound and light blockage is a big piece of that.”

Next, nearby utility lines will be buried to help with fire prevention, along with a full irrigation and sprinkler system on the crossing itself.

The bridge is expected to be ready for wildlife next year, when it’ll reconnect critical habitat for Southern California mountain lions, bobcats, deer and other animals — big and small.

“ L.A. you set a new precedent for wildlife conservation in urban areas that the world's following,” Pratt said. “And not only that, you help save this mountain lion population.”

It's long been understood that working outside in hot weather can be dangerous: Even ancient Egyptians worried about dehydration for workers building the pyramids.

Now, a growing body of research is quantifying that danger — and suggesting ways to better protect workers.

The risks extend beyond obvious concerns like dehydration and heatstroke.

"Heat makes people slower to react and worse at making decisions," says Adam Dean, a labor economist at George Washington University. "That means farmworkers driving a tractor or a construction worker operating equipment are more likely to have a fatal accident on a hot day."

But a suite of new analyses has found that regulations that provide basic safeguards like water, shade and rest for workers in hot conditions can help lower the numbers of heat-driven injuries, workers' compensation claims and even deaths.

The studies all use different datasets and methods but come to a similar conclusion, says Barrak Alahmad, an environmental health scientist at Harvard University and an expert on occupational health risks.

"States with heat standards have lower risk of heat injuries, of heat fatalities and other outcomes compared to states that don't have these heat standards," Alahmad says.

The most recent study, published in December in the journal Health Affairs, looked at California's rule protecting outdoor workers from heat, the oldest such rule in the country. Researchers found the regulations led to at least a 33% drop in heat-related deaths among workers after 2010 — an estimate of several dozen lives saved each year.

The outcome "delivers a clear message," says Dean, the study's lead author. "Heat standards, if they're adopted and effectively enforced, can significantly reduce worker deaths."

The new wave of studies comes as the federal government is considering creating new national rules to protect workers from excessive heat. Several states and local jurisdictions are also considering new standards.

The federal rules, first proposed under Biden, are now under review by the Trump administration. Their future is uncertain.

While the federal Occupational Safety and Health Administration (OSHA) has recognized for decades that heat poses risks to workers, there is active debate among worker advocates and business groups about how best to provide protections: via stringent, highly specific regulations, or with broader guidelines that allow employers to take the lead in crafting efforts specific to their own industries.

The new studies could help inform any new rules, says Jordan Barab, who was deputy assistant secretary of labor at OSHA under the Obama administration. Though the basic measures to protect workers have been well-known for decades, it's invaluable, he says, to "show that when a state actually implements these requirements that they actually have saved lives."

The California example

Federal regulators first noted that heat could put American workers at risk in the 1970s and '80s. But for years, OSHA prioritized regulating other workplace hazards. Heat issues were managed under the agency's more generalized rules, such as the "general duty clause," which required employers to maintain workplaces "free from recognized hazards."

But some states, like California, decided to go further. In 2005, after the highly publicized deaths of several farmworkers due to heat exposure, California passed the nation's first state-level regulations to protect outdoor workers from excessive heat. Requirements kicked off when temperatures exceeded 85 degrees Fahrenheit (the threshold has since been lowered further).

The rules set out to provide some simple protections: access to water, shade and rest on hot days.

For many years, California was the only state with such heat rules, setting up a natural experiment: Would heat-related worker deaths fall in California, compared to neighboring states with similar weather conditions but no such protections?

The new study suggests that, at first, the rules didn't make much of a difference. During the first few years, researchers did not find a decrease in heat-related death rates in California compared to neighboring states.

"When California first adopted a standard in 2005, it was ineffective," Dean says.

But that would soon change.

In 2010, the state strengthened the rule and deaths began to drop, the study found — eventually falling by more than 30%, with even more dramatic reductions in recent years.

The changes to the rule, Dean says, were critical. Though the initial rules required employers to provide water and shade, in practice, inspectors sometimes found problems — like undrinkable water.

So, the state clarified. Water had to be drinkable and free. And there needed to be enough shade for all workers during breaks. California also ramped up workplace inspections and launched an educational campaign to train the state's many outdoor workers about their rights.

"A critical lesson is that merely passing a heat standard is not enough," Dean says. "It was only after the state launched a statewide enforcement campaign that we started to see deaths decrease relative to the surrounding states."

The rules could have been even more effective with more consistent enforcement, says Garrett Brown, who until 2014 worked for Cal/OSHA, the state agency tasked with enforcing the rule. Even though the number of inspections increased, he says, limited staffing caused ongoing enforcement challenges.

It could have been "even more health protective for workers if there was an even more robust enforcement program," Brown says.

A growing body of evidence

The California study joins two other analyses with similar findings published in the past year.

Together, they provide important insights that could help in the design of future rules, says Alahmad. He led an analysis of heat-influenced worker injuries, published earlier this year, which found that states with heat rules had lower injury rates than those without.

Another recent study found workers' compensation claims were lower in states with heat standards compared to those without.

The next step for researchers is to suss out the most important parts of those regulations, Alahmad says: "What elements are actually most effective?"

That will be key information for regulators across the country. More than a dozen states and cities proposed new heat protection rules in 2025.

Physical media has been making a comeback. Whammy Analog Media, an Echo Park storefront specializing in VHS tapes, has been providing a place for enthusiasts and newcomers to embrace the antiquated format.

From tape collector to curator

Whammy founder Erik Varho always wanted to open his own store — he just didn’t have a clue as what it would be. A die-hard videotape lover, Varho never stopped collecting them, even after major releases ceased printing in 2006.

In 2020, fresh out of work and with VHS tapes lining the walls of his studio apartment, he started selling his tapes via Instagram.

“I was pleasantly surprised that people were actually out there buying them,” Varho said.

With the success of his online sales, Varho was able to open a brick-and-mortar store in 2022. Varho intended it to just be a retail store, but the space, he thought, was perfect for an indoor screen.

“I just kind of dove headfirst into the microcinema aspect of it,” Varho said.

Whammy’s been hosting events celebrating that grainy quality of the Video Home System — or VHS — ever since.

Meet me at the swap meet

One regular event is the Whammy VHS Swap Meet. The quarterly meet-up brings together video vendors from across Southern California to showcase their wares.

Bad Taste specializes in lowbrow horror and cult films, while Cinefile Liquidations sells vintage posters, records and other film ephemera.

“It's just kind of a place for people to display their craziest, weirdest, rarest finds and just have a place to talk about them and hang out,” Varho said.

Those rare finds include Image of the Beast from 1981, the third installment in a Christian apocalyptic thriller series about the rise of the antichrist and an evil A.I.

Whammy recently projected the film as part of its “Stuck on VHS” series, which showcases works that were only released direct to video.

A rewinding renewal

Besides an entire store, Varho also owns a storage unit filled to the brim with VHS tapes. Those who RSVP to Sunday's swap meet get a free mystery VHS tape upon entry.

He says the most frequent question he gets is if they sell VCRs. They do, but they run out pretty quickly.

Varho takes it as a good sign and says lately customers have been skewing younger and younger.

"People who didn't even grow up with VHS who are just interested in exploring movies in that way. It's a fun time to be into VHS for sure,” Varho said.

Sunday's event includes a screening of a mystery VHS.

“I can’t reveal what we’re playing, but it’s always stuff that is going to be attention-grabbing and usually pretty silly,” Varho said.

One of the most unusual of the creative treasures to enter the public domain this month is King of Jazz. The plotless, experimental 1930 musical film shot in early Technicolor centers on influential bandleader Paul Whiteman, nicknamed "The King of Jazz."

In one memorable scene, the portly, mustachioed Whiteman opens a small bag and winks at the camera as miniature musicians file out one after another like a colony of ants and take their places on an ornate, table-top bandstand.

A new video based on clips from King of Jazz has won this year's Public Domain Film Remix Contest — an annual competition that invites filmmakers from around the world to reimagine often long-forgotten literary classics, films, cartoons, music, and visual art that are now in the public domain. This means creators can use these materials freely, without copyright restrictions. In 2026, works created in 1930 entered the public domain.

Titled Rhapsody, Reimagined, the roughly two-minute video captures the King of Jazz's surreal quality: Cookie-cutter rows of musicians, showgirls, office workers and random furniture cascade across the screen as Whiteman's winking face looks on.

"I wanted to transform the figures and bodies into more dream-like shapes through collage and looping and repetition," said Seattle-based filmmaker Andrea Hale, who created the piece in collaboration with composer Greg Hardgrave. For video artists, Hale said discovering what's new in the public domain each January is a thrill. "We're always looking for things to draw from," Hale said. "Opening that up to a bigger spread of materials is amazing. That's the dream."

A massive repository of content

The Internet Archive, the San Francisco-based nonprofit library behind the contest, digitizes and provides public access to a massive repository of content, including many materials used by contest participants. "These materials have often just been in film canisters for decades," said digital librarian Brewster Kahle, who founded the Internet Archive in 1996.

This year's submissions range from a reworking of the 1930 film The Blue Angel starring Betty Boop — another public domain entrant this year — instead of Marlene Dietrich, to an AI-generated take on the 1930 Nancy Drew book The Mystery at Lilac Inn.

Kahle said the Internet Archive received nearly 280 entries this time around, the highest number since the competition launched six years ago. "Things are not just musty, old archival documentation of the past," Kahle said. "People are bringing them to life in new and different ways, without fear of being sued."

The public domain in the era of AI

Lawsuits have become a growing concern for artists and copyright holders, especially with the rise of generative AI. Recent years have seen a surge in online video takedowns and copyright infringement disputes.

Media companies are trying to address the problem through deals with tech firms, such as Disney and OpenAI's plan, announced late last year, to introduce a service allowing users to create short videos based on copyrighted characters, including Cinderella and Darth Vader.

"On the one hand, these licensing agreements seem quite a clean solution to thorny legal questions," said Jennifer Jenkins, director of the Center for the Study of the Public Domain at Duke Law School. "But what's exciting about the public domain is that material, after a long, robust 95-year copyright term, is just simply free for anyone — without a team of lawyers, without a licensing agreement, without having to work for Disney or OpenAI — to just put online," Jenkins said.

Jenkins also pointed out an interesting twist for people who create new works using materials from the public domain. "You actually get a copyright in your remix," she said. "Just like Disney has copyrights in all of its remakes of wonderful public domain works like Snow White or Cinderella." (The Brothers Grimm popularized these two characters in their 19th century collection Grimm's Fairy Tales. But their roots are much deeper, going back to European folklore collections of the 1600s and beyond.)

However, this only applies to works created by humans — U.S. copyright law currently doesn't recognize works authored by AI. And Jenkins further cautioned that creators only get a copyright in their new creative contributions to the remix, and not the underlying material.

This year's Public Domain Film Remix Contest winner Andrea Hale said she's using a Creative Commons license for Rhapsody, Reimagined. This means the filmmaker retains the copyright to her work but grants permissions that allow other people to freely use, share, and build upon it. "I'm keeping with the spirit of the public domain," Hale said.
