The Brief

California’s last nuclear power plant overcame a regulatory hurdle on Thursday when the California Coastal Commission voted to approve keeping the plant open for at least five years.

It was one of the final obstacles the controversial Diablo Canyon Power Plant had to clear to continue operating amid renewed opposition. The decision was conditioned on a plan that would require Pacific Gas & Electric, which owns the plant, to conserve about 4,000 acres of land on its property. That would prevent it from ever being developed for commercial or residential use.

The plant, located along the San Luis Obispo shoreline, now awaits federal approval for a 20-year relicensing permit.

“I don’t think, unfortunately, that anything will be happening to Diablo Canyon soon,” due to the growing energy demands of artificial intelligence, Commissioner Jaime Lee said before voting to approve the permit. Nine of the 12 voting members approved the plan.

The deliberations reignited decades-old concerns about the dangers of nuclear power and its place in the state’s portfolio of renewable energy sources. Diablo Canyon is the state’s single-largest energy source, providing nearly 10% of all California electricity.

Defeated in their earlier attempts to shut the plant, critics of Diablo Canyon used months of Coastal Commission hearings as one of their last opportunities to vocalize their disdain for the facility. Some Democratic lawmakers supported the plant but pushed for PG&E to find more ways to protect the environment.

Sen. John Laird, Democrat of San Luis Obispo County and former secretary of the California Natural Resources Agency, said on Thursday he approved of the new plan but pushed the commission to require the utility to conserve even more of its total 12,000 surrounding acres.

“If what comes out of this is the path for preservation for 8,000 acres of land, that is a remarkable victory,” Laird said.

Democratic Assemblymember Dawn Addis, whose district encompasses the plant, had also urged the commission in a letter to approve a permit “once it contains strong mitigation measures that reflect the values and needs of the surrounding tribal and local communities who depend on our coastal regions for environmental health, biodiversity and economic vitality.”

A long history of controversy

Founded in 1985, the plant’s striking concrete domes sit along the Pacific coast 200 miles north of Los Angeles. The facility draws in 2 million gallons of water from the ocean every day to cool its systems

And it has remained shrouded in controversy since its construction 40 years ago. Environmentalists point to the damage it causes to marine life, killing what the Coastal Commission estimates are 2 billion larval fish a year.

The commissioners on Thursday were not deciding whether to allow the plant to stay open but were weighing how best to lessen the environmental impacts of its operation. A 2022 state law forced the plant to stay open for five more years past its planned 2025 closure date, which could have led to significant political blowback against the Coastal Commission if it had rejected the permit.

Gov. Gavin Newsom reversed a 2016 agreement made between environmental groups and worker unions to close the plant after the state faced a series of climate disasters that spurred energy blackouts. Popular sentiment toward nuclear energy has also continued to grow more supportive as states across the country consider revitalizing dormant and aging nuclear plants to fulfill ever-increasing energy demand needs.

The 2022 law authorized a $1.4 billion loan to be paid back with federal loans or profits.

Groups such as the Environmental Defense Center and Mothers for Peace opposed the permit outright, citing concerns about radioactive waste, which can persist for centuries, and its cost to taxpayers.

“We maintain that any extension of Diablo is unnecessary,” and that its continued operations could slow the development of solar and wind energy, Jeremy Frankel, an attorney with the Environmental Defense Center told the commission Thursday.

The California Public Utilities Commission last year approved $723 million in ratepayer funds toward Diablo Canyon’s operating costs this year. It was the first time rate hikes were spread to ratepayers of other utilities such as Southern California Edison and San Diego Gas & Electric and was authorized by lawmakers because the plant provides energy to the entire state.

How the plant will be funded has also garnered scrutiny in the years since Newsom worked to keep it open. Last year, the Legislature nearly canceled a $400 million loan to help finance it.

As much as $588 million is unlikely to come back due to insufficient federal funding and projected profits, CalMatters has reported.

Proponents of the plant pointed to its reliability, carbon-free pollution and the thousands of jobs it has created.

Business advocacy groups emphasized their support for the plant as boosting the economy.

“It is an economic lifeline that helps keep our communities strong and competitive,” Dora Westerlund, president of the Fresno Area Hispanic Foundation, said at a November meeting.

For Tré Willingham, pursuing a doctorate degree at UC Irvine has felt isolating at times. Often the only Black student in his science classes, he recalls being the last one to be chosen when activities required a lab partner. He also has never had a Black professor.

“It’s very disheartening to never see anyone that looks like you,” said Willingham, who studies applied physics. “It makes it hard to believe that you can get there, and especially get there and actually be yourself.”

For Willingham and students like him, the state-funded Cal-Bridge program is helping them pursue their dreams of landing a doctorate in the sciences and joining the next generation of STEM professors. The program provides financial support, research opportunities and diverse mentors of similar backgrounds.

Such mentors make “it much easier to start to navigate these spaces and also believe that you can get to the other end,” Willingham said.

Cal-Bridge was founded in 2014 to help undergraduates at Cal State campuses pursue a doctorate in STEM in partnership with the University of California, helping to close the diversity gap in science fields. About 70% of the program’s 406 students have been admitted to doctorate programs. Three quarters of the program’s students are of color, almost half are women, and nearly two-thirds are first generation.

Studies have noted that the climate of STEM higher education programs is often unwelcoming for some minority populations. Women make up over half of the undergraduate student population at Cal State campuses, yet account for only 36% of the system’s STEM students. At UC campuses, only 24% of STEM undergraduates are Latino or Hispanic, 4% are African American and 1% are American Indian.

From Cal-Bridge’s first cohort of five undergraduate students, the program has grown to support about 60 each year. It has expanded from astronomy and physics to now include computer science and math. Students in the program can receive stipends, tuition assistance, mentorship and professional development.

But the journey to diversifying the STEM teaching field is very long.

So far, 15 Cal-Bridge participants have earned a doctorate. It takes students about eight years after joining Cal-Bridge, usually done during their junior year, to complete a doctorate — two years as an undergraduate and six years to complete their doctorate education.

“It’s only been 12 years since we started, so only this small group is getting their Ph.D. right now,” said Dr. Alexander Rudolph, Cal-Bridge’s executive director and founder. “But eventually we expect there to be more like 30 to 40 to 50 a year getting their Ph.Ds.”

The state Legislature has given $14 million over recent years to the program, which also has a sliver left over from an older National Science Foundation grant.

The program might also get a helpful boost in the Legislature as California pushes back against federal efforts targeting university equity initiatives.

Democratic Assemblymember David Alvarez of Chula Vista introduced Assembly Bill 2660 in April to codify Cal-Bridge as a coordinated partnership between community colleges, Cal State universities and University of California campuses. Rudolph hopes that will help secure annual or multi-year funding for Cal-Bridge in lieu of making requests each year.

Alvarez told CalMatters that as the federal administration cut back on student loans and grants for Hispanic-Serving Institutions, California should do more to support its students.

“The lack of representation from first-generation students in the Ph.D. level of education speaks for itself,” said Alvarez. “We need to do something in California to demonstrate that we still believe that we have strength in diversity of our Ph.Ds, of our academia, and this (Assembly bill) is one way to try.”

Financial assistance allows students to prioritize academics 

Willingham, the UC Irvine student, hadn’t considered pursuing a doctorate earlier in his life. Now 31, the first-generation scholar is pursuing his doctorate with the goal of one day becoming a professor.

“No one around me was a doctor of anything,” said Willingham about his family and friends growing up.

Willingham grew up in Littleton, Colorado where he attended Columbine High School. After high school, his father, who had served in the Air Force, and Willingham moved to Atlanta. In 2017, he moved to California where he began his higher education journey. He is now the father of two children, ages 12 and two, balancing family time with his studies.

Today, Willingham’s research focuses on creating new quantum materials and exploring how they could be used in future sensors and electronic devices.

Cal-Bridge has four programs: undergraduate, summer research, doctoral and postdoctoral. The undergraduate program is open to STEM students at Cal State campuses and community college students who plan to transfer to a Cal State. It receives up to 100 applications per year; about 60 students were accepted this past year.

Willingham attended El Camino College and Compton College simultaneously to finish his associate degree quickly, then joined Cal-Bridge’s undergraduate program after transferring to Cal Poly Pomona. There, the program gave him $10,000 during each of his junior and senior years, which helped him get a car to commute to school from Los Angeles and stay focused by working fewer hours as a tutor.

“I was able to just sort of focus my attention a little better, not having to always think about how I’m going to pay the next bill,” said Willingham.

Later in Cal-Bridge’s doctoral program, Willingham received $40,000 in financial support for his first year of graduate school at UC Irvine. He used $16,000 to pay his tuition and the rest for living expenses.

Mentorship helps students find their place in STEM 

It took Dr. Katy Rodriguez Wimberly, a Cal-Bridge alum, 13 years to become a research faculty member. She is now an astrophysics assistant professor at Cal State San Bernardino.

Wimberly researches near-field cosmology, studying neighboring galaxies that may be some of the first ever formed.

“It’s almost like galactic archaeology, like I’m looking at these little almost-fossil galaxies to learn more about the early universe and where everything came from,” said Wimberly.

She is also now the director of mentorship for Cal-Bridge. During her junior year as an undergraduate, she joined Cal-Bridge’s first cohort, helping her imagine what being an astronomer would be like.

The mentors and the program’s monthly workshops showed her that while she didn’t see many Latina women like her teaching STEM on her campus, she could do it. When she was an undergraduate at Cal State Long Beach, she said, there were only two women professors from about 20 faculty in her department, and none of them Black or Latino.

Cal-Bridge provided Latino mentors she wasn’t finding anywhere else.

“It wasn’t like they were teaching me in a classroom, but they did kind of provide that cultural and kind of identity support,” said Wimberly.

Wimberly had applied to 11 doctorate programs as a senior undergraduate and was denied by all of them. Next, she applied and was accepted to Cal State Long Beach to pursue a master’s in physics. There, she raised her GPA, reapplied to doctorate programs and was accepted to UC Irvine. She graduated in 2021 with her doctorate in physics.

At UC Irvine, Wimberly created a peer mentorship program for Cal-Bridge students as a way for alumni and graduate students of the program to support the undergraduate students. Mentors and mentees meet in small groups once a month, as well as have one-on-one meetings.

“I structured it in a way to be more like, this is just your older cousin that’s telling you how to get through things,” Wimberly said.

After she finished her doctorate, she had a three-year, full-time fellowship with the National Science Foundation. She served at UC Riverside with her former mentor, Laura Sales, an astronomer from Argentina and associate professor at the university.

Learning from Sales made her feel more comfortable embracing her identity as a Latina. Sales taught her that she didn’t have to be an expert in all areas of astronomy, but that she would work alongside experts in different areas.

Now as a professor herself for the last three years at Cal State San Bernardino, Wimberly offers the same mentorship to her students. Anytime she sees a Latina student who doesn’t have support from someone with a similar background, she tries to provide that support.

“Just because I know it can be so difficult,” said Wimberly.

Claire Rogers, a student at UC Irvine pursuing a doctorate in physics, knew she wanted to attend graduate school, but she didn’t realize how isolating the experience would be as the only woman in the room. She is a Cal-Bridge doctorate scholar researching observational astrophysics, looking for planets outside of the solar system to determine if there is life on those planets. She also focuses on how stellar astrophysics affects measurements when looking for planets.

Rogers was an undergraduate at Cal Poly Humboldt and joined Cal-Bridge during the first year the program expanded to her campus.

“Cal-Bridge was really helpful for providing a network of students at the same phase of their career at different CSU campuses but still working towards similar goals,” said Rogers.

She said that since the department on her campus was small, Cal-Bridge allowed her to connect with students at other campuses who were in similar positions.

The program provided her two mentors, a professor at her campus and a professor at UC Berkeley. The program also offered her guidance in applying for graduate school.

“I’m sure it made a huge difference in my grad school essays, getting that feedback,” Rogers said.

Rogers participated in an undergraduate summer research program at the University of Wyoming through Cal-Bridge, where she dabbled in astrophysics research for the first time. Cal-Bridge’s summer program is open to community college and Cal State undergraduate students and allows students to participate in research projects at partner institutions. Out of around 200 applications, only 50 to 60 students get accepted to the summer program.

“I really like spending time at a telescope … and dealing with all of the problems that come up when you are running a telescope overnight,” she said.

She was usually the only woman in her undergraduate classes, and in graduate school there were only three women in her cohort of 22 students.

“I got very accustomed to being the only woman in a room,” said Rogers.

She mentioned feeling isolated during her first year at UC Irvine, noticing that her classmates rarely showed up when she organized study groups and that the men in her lab would change the conversation when she entered the room.

“I had a really hard time my first year with reconciling that I felt very unwelcome,” said Rogers.

She eventually found a support network outside of her original cohort, getting closer to other doctoral scholars in Cal-Bridge and having monthly movie nights together.

“Cal-Bridge has made a huge difference to my career and my, sort of, finding my space in this field,” said Rogers.

Rogers hopes to one day become a professor and be able to teach while continuing her research in observational astrophysics.

“When I was new to physics it made a big difference for me to have women professors,” said Rogers. “I think it’s important for future students to also have that resource and that support, and I would like to be able to provide that.”

California scored another win against the Trump administration in their battle over how to address the homelessness crisis here and nationwide.

A federal judge this week shot down the federal Department of Housing and Urban Development’s 2025 attempt to divert money away from permanent housing and instead fund temporary shelters and programs that require sobriety. But the judge stopped short of banning the Trump administration from making such changes in the future.

“The federal court’s decision to reject the Trump-Vance Administration’s attempt to disrupt essential housing services for people experiencing homelessness, including families, seniors, veterans, and people with disabilities, is both appropriate and just,” Renee Willis, chief executive of the National Low Income Housing Coalition, wrote in a news release.

In November, the Department of Housing and Urban Development said jurisdictions applying for about $4 billion in federal Continuum of Care funding can’t spend more than 30% of it on permanent housing — a move that would result in a significant cut to the type of long-term housing that for years has been a cornerstone of the fight against homelessness.

Last year, California communities spent about 90% their share of that money on permanent housing.

A group of states, including California quickly sued. San Francisco, Santa Clara County and a group of national homelessness nonprofits filed a separate lawsuit. In December, a federal judge in Rhode Island temporarily blocked the changes. In February, Congress ordered HUD to renew grants from 2025 under the old rules.

This week, U.S. District Judge Mary McElroy partially granted the plaintiffs’ request for summary judgement in both cases. She ruled that the federal agency did not try to foresee the harm its “breakneck” transition away from the country’s longstanding “housing first” model – which prioritizes getting people into housing without first forcing them to seek treatment – would have on the country’s homeless individuals.

“Overall, the actions undertaken by HUD in attempting to hastily eliminate its housing first approach serve as the hallmark of unreasoned decision making,” McElroy wrote.

HUD did not immediately respond to a request for comment.

The ruling wraps up both cases, unless the Trump administration decides to appeal.

But the fight isn’t over. The Trump administration tried again last month, moving to shift 2026 federal funding away from permanent housing and the housing first framework. Housing advocates tried to challenge that latest shift in the prior lawsuit. The judge rejected that attempt, but welcomed the plaintiffs to file a new lawsuit.

The housing advocates said they are weighing their next steps.

Topline:

Where the greatest risks are: Areas around downtown Los Angeles, the San Gabriel Valley, and northern Orange County may see hazardous air on the evening of July 4 due to particle pollution from fireworks, according to the South Coast Air Quality Management District. Riverside County and San Bernardino could see hazardous air the next day as the particles from fireworks move east and combine with the region’s elevated levels of air pollution.

Other risks: The Inland Empire and most of Los Angeles and Orange counties — that is, nearly all of SoCal — may see unhealthy air at times throughout the weekend, as they do every year.

Why it’s unhealthy: Exposure to particle pollution can cause chronic coughs in healthy people and flare-ups of symptoms for people with asthma and chronic obstructive pulmonary disease, according to the American Lung Association. If you’re in an area where people set off personal fireworks, the organization said those can be even more dangerous, since they’re closer to the ground and the air we breathe.

What to do: Stay inside if you can, and avoid physical activity outside. Unlike the recent fire at the Lineage Logistics warehouse in Boyle Heights, air quality officials say running air conditioners in your home will help, as will air purifiers, though they recommend against turning on fans that bring in outside air.

Other issues: Visibility in Orange County and the Inland Empire may be low Saturday night due to a soupy blend of high humidity and particle pollution.

How long the advisory lasts: It’s in place from 5 p.m. July 4 until 3 p.m. July 5.

The U.S. telecasts of this summer's World Cup games are drawing a record number of viewers. Fox Sports, which broadcasts the games in English, reports an average of 5 million viewers per match across 72 group stage matches. And Telemundo says nearly half of all World Cup viewers in the country are watching its Spanish language coverage.

Wednesday night, fans celebrated as the U.S. men's national soccer team knocked out Bosnia Herzegovina's team two-nil during the latest round of the Copa Mundial, as it's known in Spanish.

At Café Brasil in Culver City, California, Giselle Rosas and her mother Graciela Reyes, who were both born in Mexico, cheered for the U.S. team, along with Telemundo's famously exuberant announcer Andrés Cantor.

"That's the best part for everybody," Reyes said, imitating Cantor's long "Goooooool" calls.

Rosas noted the growing popularity of soccer in the U.S. "thanks to immigrants," and she said it's more fun to watch the World Cup in Spanish.

"A million percent. We like the excitement," said Rosas, "the feeling, the sentiment, the ambience, it's a night and day difference."

That kind of passion, to date, has translated to an average of 4.6 million World Cup viewers of Spanish-language sportscasts on Telemundo and Peacock streaming services per match, according to NBCUniversal.

"This is the most watched World Cup ever in Spanish language in this country. The numbers are just mind blowing, really," says Miguel Lorenzo, a senior vice president at Telemundo Deportes.

"Basically, half of the country of the United States is watching the World Cup in Spanish on Telemundo. But we also know that only 20% of the U.S. population is Hispanic," says Lorenzo. "We're seeing audiences that are bilingual, that are Spanish dominant, that speak English enjoying World Cup coverage."

According to Nielsen ratings, 20% of Telemundo's World Cup viewers speak English as their primary language. And overall, Lorenzo says the viewership on its telecasts has increased by 122% since the 2022 World Cup Games.

He says excitement has been highest for the winning matches by Mexico and the U.S., and the network's social media platforms have surpassed a record-breaking one billion views.

"I can't tell you how many comments I've seen where people are saying, 'I don't speak a lick of Spanish, but I want to watch it on Telemundo because it just sounds more exciting. And maybe by the end of the World Cup, I'll learn Spanish,'" Lorenzo says. "Joy and excitement and drama: it's language agnostic, it's universal."

Unlike Fox, which runs commercials during hydration breaks for the players, Telemundo keeps its cameras on the field. That's something very much appreciated by fans like comedian Trevor Noah.

"We're seeing the players on the pitch discussing what's happening. You see which coach is more stressed…This is part of the game," Noah said during one of the World Cup parties he hosts on his YouTube channel. "When you cut to ads, you lose the stress, you lose the joy, the anticipation. So shout out again, Telemundo: Really, really amazing coverage."
