The Brief

When residents took it upon themselves to paint crosswalks around a popular West L.A. park, city crews — citing federal and state regulations — scrubbed them away Friday after the DIY project went viral on social media.

But in an interview with LAist, Los Angeles City Councilmember Traci Park, who represents the area, said crews removed the paint job even after she requested that the DIY crosswalks be left in place.

“ What is the worst that could possibly happen?” Park said in an interview with LAist. “This intersection is at least slightly more safe [with the DIY crosswalks] while we try to figure out the next steps.”

The backstory

Over two Saturdays in late May, Sawtelle resident Jonathan Hale, along with friends, neighbors and the consultation of the Crosswalk Collective, painted yellow crosswalks around Stoner Park ahead of summer camp programs.

"It's just a busy area and I didn't want to wait for somebody to get injured or killed before we did something," Hale previously told LAist.

Three days after the local newspaper reported on the community’s actions, the L.A. Department of Transportation got rid of the crosswalks.

Park, who represents areas including Sawtelle, Venice and West L.A., said that she’s made a request “ through the proper channels” to assess what speed safety treatments could be installed around Stoner Park.

“ I don't particularly want to see limited city resources being used in a war of attrition with neighbors who are just trying to make their community safe,” Park said. “I hope that we can all get to the table and work on this together.”

What city transportation officials had to say

In a statement to LAist, the Department of Transportation said it “shares the community’s goal to make neighborhood streets safer, and is assessing these locations to install crosswalks that comply with State and Federal requirements.”

Diego de la Garza, who was an associate director of transportation under former Mayor Eric Garcetti, said state law makes the city liable for dangerous conditions on its property in the public right of way.

"A homemade crosswalk is a dangerous condition because it creates the illusion of safety when there is none," de la Garza said, adding that several factors, including lighting, signals and speed limits, need to be considered.

Next steps

Park expressed solidarity with the sentiment that led residents to take matters into their own hands and also the frustration that followed when the city sent crews to remove the crosswalks soon after they were publicized.

“ They actually looked pretty good to me,” Park said of the crosswalks.

Ultimately, Park said she wished her constituents had reached out to her office before they painted the crosswalks.

“ We don't have to get into little tit-for-tats like this — that isn’t going to solve the problem,” Park said, adding that her office regularly asks the Department of Transportation to assess safety needs in the public right-of-way. “At the end of the day, we have to do it right.”

In its statement, the Department of Transportation encouraged Angelenos to request traffic safety improvement requests through MyLA311 or by contacting their City Council representative.

Everyone knows the frustration of bad sleep on a hot night, tossing and turning in the sheets as the hours slip away.

That experience is becoming more common thanks to climate change, according to a new study from the research organization Climate Central. The analysis finds that on average, people around the world lose about 56 hours, or seven full nights of sleep each year to uncomfortably warm temperatures. About 10% of that lost sleep—roughly 5 hours—can be pinned to human-driven climate change.

"Summertime is hot. It's always been," says Kristina Dahl, the lead scientist at Climate Central. "But climate change is making them hotter, and making nights hotter. So it's really amplifying the sleep loss that would happen naturally."

The study looked at temperature records from 1,300 cities around the world. The Climate Central team knew from a study published a few years earlier that the amount of time people sleep is tightly tied to overnight outdoor temperatures. So they could extrapolate the total time people spent sleeping based on the temperatures where they lived. That number represented the real sleep people got in a world that has been heated up by climate change.

Then, the Climate Central researchers used a climate model that presents a hypothetical world: one where human-driven climate change hasn't happened. The researchers could estimate temperatures in all those same locations—and see how much people would have slept in that cooler scenario.

The difference, Dahl says, isn't enormous for each person: it's on the order of 5 hours a year so far. But that number has doubled since the 1970s, and it will continue to rise as climate change marches onward, she says.

That's in part because overnight temperatures have crept upward much faster than daytime ones. The causes are complex, but one factor is the shape of the atmosphere: At night, the layer of air closest to the ground, where people actually live, is short and compact. During the daytime, that layer expands. Heat absorbed during the day gets trapped into that compact band of air during the night, pushing temperatures up.

Sleep is tightly tied to temperature. Sleep laboratory studies consistently show that hotter and more humid conditions degrade sleep quality. People's ability to fall asleep in the first place decreases, and the sleep that does occur gets fragmented and less restorative.

Particularly, says sleep doctor Daniel Rifkin from the sleep consultancy group Ognomy Sleep, the type of sleep that leads to dreams: REM.

"If it's too hot," he says, "your REM sleep is extremely broken, and we lose our dreams."

Sleep lab studies helped scientists understand the best temperature conditions for sleeping indoors. But until recently, it wasn't clear how real-world weather conditions affected people's sleep.

But a few years ago, environmental data scientist Kelton Minor and his colleagues set out to figure out that relationship. They collected sleep data from nearly 50,000 Fitbits around the world, along with detailed overnight temperature data from sleepers' locations.

"The warmer it gets, the less that people sleep," says Minor— especially once nighttime temperatures crept above about 50 to 59 degrees Fahrenheit. Beyond that, Minor and his colleagues found, "every additional increase per degree on that hot side leads to progressively less sleep."

The new Climate Central analysis used Minor's sleep-temperature relationship to estimate climate-induced sleep loss.

Sleep is already a precious and threatened commodity, says Minor. In 2015, the Centers for Disease Control and Prevention declared sleep problems like disorders and simple insufficiency to be a public health crisis.

So far, the climate impact adds up to just a few minutes a day during summertime. But because the relationship between sleep loss and health is so strong, the cumulative impacts of that loss on public health could be significant, says sleep doctor Rifkin. The impacts also fall hard on people who don't have access to cooling technologies such as air conditioning, or who can't afford to run them.

"Heat really finds the vulnerable people first," he says. "It affects those the most that need the help the most."

He recommends doing whatever possible to cool your sleep space. If nothing else is possible, sticking your feet outside the sheet or blanket can help your body shed heat and cool down enough to sink into sleep.

Beyond those recommendations, Dahl says one of the best sleep aids isn't a pill or a meditation app, but cutting back on burning fossil fuels, the primary driver of climate change.

Artist Betye Saar, whose work reflects Black identity, culture and spirituality, died Sunday morning in Los Angeles at 99.

Saar’s death was confirmed Monday by relatives. She would have turned 100 this week.

A central figure of the 1960s Black Art Movement, Saar pioneered assemblage boxes, or sculptures made of found objects, and reclaimed Jim Crow-era memorabilia as powerful totems of Black liberation.

“Her symbolically rich body of work has evolved over time to demonstrate the environmental, cultural, political, racial, technological, economic and historical context in which it exists,” according to Roberts Projects, the Los Angeles gallery that represents her.

Saar began her career in design and shifted to art at age 35. She continued to make art into her 90s. She grew up in Pasadena and was part of a community of Black artists in nearby Altadena; she often cited Simon Rodia’s Watts Towers as an early source of inspiration.

Saar’s practice incorporated painting, printmaking, sculpture and found objects including dolls, washboards and other antiques. Boats, clocks, cages and altars recur in her practice, as well as symbols of the occult and cosmology. She often referenced her astrological sign of Leo in the form of lions, punctuating many works.

“Her appropriation of Black collectibles, heirlooms and utilitarian objects are transformed through subversion,” the gallery said. “Among the older generation of Black American artists, Saar is without reproach.”

Made in 1969, “Black Girl’s Window,” was groundbreaking. Still, it wasn’t widely celebrated until decades later, and it was acquired by the Museum of Modern Art in New York in 2019.

“There weren’t that many galleries in Los Angeles at the time and there certainly weren’t any for Black artists,” she once said in an interview.

“The Liberation of Aunt Jemima,” created in 1972, is one of her most important works. It features memorabilia she collected that denigrated Black people, included a “mammy,” or 19th century minstrel character who smiled while serving white slave owners.

In Saar’s hands though, the figure is reclaimed: She smiles, but holds a rifle and has a hand grenade.

It came in response to the 1968 assassination of the Rev. Martin Luther King Jr. in Memphis, Tennessee. Saar said King’s death “triggered a rage within me, and the mystic transformed into the warrior.”

“I had a lot of hesitation about using powerful, negative images such as these — thinking about how white people saw Black people, and how that influenced the ways in which Black people saw each other,” Saar said. “What saved it was that I made Aunt Jemima into a revolutionary figure.”

After more than 130 years, Quaker Oats announced it would retire its Aunt Jemima brand in 2020, acknowledging the logo and its origins were “based on a racial stereotype.”

Saar taught and mentored generations of Black artists, including painter Kerry James Marshall.

Though Saar’s work was exhibited in a 1975 solo show at the Whitney Museum of American Art, in the decades that followed large institutions have exhibited her work only sporadically. In 2019 though, the Los Angeles County Museum of Art and MoMA mounted concurrent solo shows.

In spring 2026, Saar was inducted into the American Academy of Arts and Letters.

“She had boundless energy for making art. I think she had a lot to say and was tired of the art world being dominated by white males,” said Angela Robinson Witherspoon, who produced and directed a documentary in 2023 on Saar’s life. “Betye Saar: Ready to Be A Warrior” features interviews with John Legend, Tina Knowles and other prominent voices.

“She was raising her three young daughters and she wanted to be part of the Civil Rights Movement,” Robinson Witherspoon said.

“Let’s Get It On: The Wearable Art of Betye Saar,” which focuses on costume design, is currently on view at Roberts Projects in Los Angeles, and there are 26 of an eventual 100 dolls on view at The New York Historical in Manhattan.

International students in Southern California say new visa time limits imposed by the Trump administration don’t square with the realities of trying to complete a degree in four years.

Under the new rules, there is now a limit to how long international students can remain in the country, as opposed to remaining in the U.S. for as long as it took to complete their degree program.

Department of Homeland Security Markwayne Mullin said in a statement that the previous rules allowed thousands to become “forever students” by perpetually enrolling in courses to avoid departure. LAist has reached out to the department about how many of these students are in Southern California.

California State University spokesperson Amy Bentley-Smith said international students from over 160 countries “add to the rich diversity, voices, and perspectives that enrich our campuses.”

Rachel Zaentz, senior director of strategic and critical communications at the University of California Office of the President, told LAist in a statement that the new policy “significantly changes the way international students have studied in the U.S. for decades.”

“The prior Duration of Status rule provided international students and scholars with the time needed to complete their studies, conduct research, teach, train and work, provided they maintained their nonimmigrant status, in support of the country’s global competitiveness and innovation economy,” she added.

Studies have also shown that international students help boost colleges’ financial footing since they aren’t eligible for aid.

In a letter to DHS , the UC Office of the President said international students contributed $6.4 billion to California’s economy during the 2023-24 academic year and supported more than 55,000 jobs.

Katherine S. Newman, UC System Provost and executive vice president for academic affairs, wrote that the then-proposed visa limits would deter international students from pursuing doctoral programs in the U.S. and instead turn to countries like China, which has been heavily investing in doctoral programs.

Additionally, the letter highlights how students take varying times to complete their degrees. The new changes set limits to four years for visas with an option to apply for extensions. But Newman wrote that the graduation rate for almost 90% of incoming freshmen is six years.

Adding to worries 

Reva Kaneri, a graduate student from India pursuing a degree in data science from the University of California, San Diego, said the new rules affects her mental health.

“It adds a layer of uncertainty and pressure that international students already live with,” she said. “As someone who simply came here to pursue an education, build a career, and experience a new country, that uncertainty can be scary at times.”

The new visa limits, she said, reduces the flexibility international students had to find a job.

Kaneri took out a loan to pursue her degree so she wouldn’t be a financial burden on her parents.

“At one point, I genuinely thought I’d have to give up on my dream because every door seemed closed,” said Kaneri, who also worked on campus as a teaching assistant to help cover some of her tuition.

But, she said, it’s worth it.

“I honestly didn’t want to settle for average. I wanted to learn from some of the best people in the world. The U.S. has an incredible tech ecosystem, from Silicon Valley to Seattle and beyond, and many of the world’s leading technology companies are headquartered here,” Kaneri said. “I wanted the opportunity to work with talented people, network with founders and innovators, and absorb as much as I possibly could. For the goals I had, I felt there wasn’t a better place.”

For Rohit Nair, an international student from India pursuing a master’s degree in business analytics at USC, finding a job is not optional.

He took out a loan of around $87,000 to come to the U.S. to study. But if he doesn’t get a job in the U.S. after graduating, it would be impossible for him to pay it back in Indian rupees.

“ I would be in generational debt if I take that step,” he said.
