The Brief

The most important stories for you to know today
  • Carved in blink of an eye
    The Grand Canyon in Arizona got carved by water over millions of years of slow but steady erosion. Two similarly-sized canyons on the moon got carved by flying rocks in about 10 minutes.

    More context: These two canyons formed in the wake of an asteroid or comet smashing into the moon, a crash that sent streaks of rocky debris flying at incredible speeds, according to a new analysis in the journal Nature Communications.

    About the canyons: The two canyons, called Vallis Schrödinger and Vallis Planck, are located on the far side of the moon, so they can only be seen from orbit — not from Earth. Each canyon is over 165 miles long and more than 1.5 miles deep.

    Read on... more on the analysis on how these two canyons were formed.

    The Grand Canyon in Arizona got carved by water over millions of years of slow but steady erosion. Two similarly-sized canyons on the moon got carved by flying rocks in about 10 minutes.

    That's because these two canyons formed in the wake of an asteroid or comet smashing into the moon, a crash that sent streaks of rocky debris flying at incredible speeds, according to a new analysis in the journal Nature Communications.

    "This was a dramatic impact that was followed by a series of smaller impact events that excavated these canyons in, you know, roughly 10 minutes," says David Kring with the USRA Lunar and Planetary Institute in Houston.

    "That would have been an extraordinary sight to see," he adds. "Not that I would have wanted to be on the lunar surface, but I would have liked to have been a safe distance above the surface to watch all of this unfold."

    The two canyons, called Vallis Schrödinger and Vallis Planck, are located on the far side of the moon, so they can only be seen from orbit — not from Earth. Each canyon is over 165 miles long and over 1.5 miles deep.

    "These are extraordinary canyons, but they're hidden, if you will, and kind of mysterious because they're on the far side in the lunar South Pole region," says Kring, who has long wondered exactly how they formed.

    The canyons look like remarkably straight lines that extend outward from a circular crater that is the Schrödinger impact basin, the result of a large impact that occurred around 3.8 billion years ago.

    To better understand how this impact basin and its accompanying canyons were created, Kring teamed up with Danielle Kallenborn, who is now a Ph.D. student at Imperial College London, and Gareth Collins, also at Imperial College London. They used images obtained by NASA's Lunar Reconnaissance Orbiter to carefully map the crater, the canyons, and the deposits of ejected rock that rained back down.

    When the impactor hit the moon, it was moving at roughly 38,000 miles per hour, says Kring, and would have penetrated to a depth of about 15 miles. As it did, it threw up an asymmetrical pattern of debris, a curtain of rock which plummeted back down to the surface.

    "These canyons were produced by two concentrated streams of rock in that curtain of debris," says Kring. "Those clusters of rock in that curtain hit the lunar surface in just a staccato series of impacts."

    These impacts excavated a series of round craters that line up, which means that the canyons were "produced by a series of small impact events that form a chain," he explains.

    The amount of energy needed to produce these grand canyons on the moon is 1200–2200 times larger than "the nuclear explosion energy once planned to excavate a second Panama Canal on Earth, more than 700 times larger than the total yield of US, USSR, and China's nuclear explosion tests, and about 130 times larger than the energy in the global inventory of nuclear weapons," the researchers write in their report.

    Even though these particular lunar craters aren't visible from your backyard, Kring says there are similar, but smaller canyons on the near side of the moon that's visible in the night sky. These radiate out from the bright spot that is Tycho Crater.

    "On a clear, clear night, Tycho, which is a little bit below the equator, has beautiful white rays," says Kring. "Those white rays are the same phenomenon, but just at a very small scale compared to Schrödinger."

  • Craft community hosts bi-weekly gatherings
    Young people knitting
    Groups of knitters and crocheters attending Knitting Tree LA's Gen Z Knit Night.

    Topline:

    Gen Z Knit Night is Arden Siadek’s brainchild. She noticed a gap in programming for younger crafters and set out to fill it. Since its launch, the event has drawn between 40 and 50 attendees.

    Background: Before joining the Knitting Tree, Siadek had been crafting for about 15 years, a practice introduced by her grandmother. Her interest ebbed over time, including a long break after struggling through her first project — a scarf.

    Read on ... for more on how Gen Z has taken to knitting.

    Knitting and craftwork may once have been viewed as hobbies for older adults, but some Gen Zers are challenging that stereotype and carving out their own spaces. Enter Arden Siadek, a Gen Z crafter who found her way to Inglewood’s craft community, The Knitting Tree,  and now works there while hosting its new and rapidly growing Gen Z biweekly Knit Night gatherings.

    Craftwork has seen a recent surge as people look for offline spaces disconnected from social media. The event, which launched in February, has steadily gained popularity.

    Gen Z Knit Night is Siadek’s brainchild. She noticed a gap in programming for younger crafters and set out to fill it. Since its launch, the event has drawn between 40 and 50 attendees.

    The LA Local attended a recent gathering and spoke with Siadek about its success.

    Before joining the Knitting Tree, Siadek had been crafting for about 15 years, a practice introduced by her grandmother. Her interest ebbed over time, including a long break after struggling through her first project — a scarf.

    That changed when she was preparing to leave for college and rediscovered yarn in her closet. The find, combined with the unexpected free time during the pandemic, reignited her interest.

    “Something just clicked for me in a way that you’re still making something artsy and creative, but you’ve got a structure that you can rely on, so it feels really comfortable and meditative,” Siadek said.

    Nearly two years ago, she began spending more time at the Knitting Tree and eventually joined the staff. She saw an opportunity to build a “third space” where people could connect offline and step away from the constant noise of social media and the news.

    “I was looking for a space like a club where I could knit and craft with other young people,” Siadek said. While the Knitting Tree has hosted potluck meetups for years, the gatherings were not specifically geared toward younger crafters. “I really wanted something specifically for younger people because yarn shops can skew a little older. We wanted an additional space — a ‘yes, and.’”

    She pitched the idea to owner Annette Corsino-Blair, who supported it.

    During a recent Knit Night, the shop buzzed with conversation as young crafters worked on projects ranging from sweaters and scarves to socks, flowers, Dungeons & Dragons-themed crochet and even “emotional support chickens.”

    Attendees mingled, debated the merits of knitting versus crochet and formed new friendships. Some arrived with friends; others came alone and quickly connected with others. The event offered a welcoming alternative to bars, clubs and digital spaces — a place to disconnect and create.

    Participants said the gathering provided a sense of relief and community.

    “This is getting me off my phone,” said Gemma Chao, a knitter in her 20s, as she worked on a crocheted flower.

    Another participant told The LA Local that they loved that they could disconnect from the heaviness of the world in a place where the responsibility of life and work — and mean girls — could not reach her.

  • Org expands on CA campuses, stoking tensions
    A person with a red Trump hat with their hands raised and holding a USA flag in an auditorium seated with people.
    An attendee raises their arms during a Turning Point USA event at the University of California, Berkeley on Nov. 10, 2025. Two months after Turning Point USA founder Charlie Kirk was killed, the tour made a stop in California at UC Berkeley.

    Topline:

    Turning Point chapters continue to grow on California campuses months after Charlie Kirk’s assassination.

    Why it matters: Campuses are seeing tensions rise as conservative students become more vocal both in and out of the classroom.

    The backstory: While conservative students say they’ve felt hesitant to speak aloud in the past, they now say emerging Turning Point chapters have helped them break out of their shells in California, with one student even describing them as a “safe space.”

    Despite being a political junkie and longtime fan of conservative commentator Charlie Kirk, Shasta College senior Raymond Randolph hesitated to speak up about politics on campus. But Kirk’s assassination during a Turning Point USA event at a Utah university in September 2025 changed that.

    “God was calling me up to the plate,” said Randolph.

    The day after Kirk’s death, Randolph reached out to Turning Point, which Kirk had founded, to start a chapter at his college in Redding. As the chapter’s president, he said he’s not alone in feeling mobilized after Kirk’s assassination.

    “It drove a lot of people like me to get up and do something,” he said.

    While conservative students say they’ve felt hesitant to speak aloud in the past, they now say emerging Turning Point chapters have helped them break out of their shells in California, with one student even describing them as a “safe space.”

    As of March this year, Turning Point USA told CalMatters it has 1,462 active college chapters nationally. Over 70% of those were founded after Charlie Kirk’s assassination. Turning Point’s presence has nearly tripled on California campuses as of March, with 78 of the state’s 119 active college chapters founded after Kirk’s death.

    But conservative views continue to be overshadowed by more liberal voices on California campuses as tensions persist both in and outside classrooms, students and professors say.

    “Most of [the liberal students] think we’re racist, most of them think we’re fascists … especially in California,” Randolph said.

    Kameron Tessier, president of the statewide California College Democrats organization, said Turning Point’s rhetoric is “disgusting and very bigoted” and must be investigated on campuses.

    “I’m a firm believer in the First Amendment, but also the First Amendment has its consequences,” said Tessier, a senior at UC Santa Cruz. “If they are pushing actively dangerous rhetoric on campuses, then I think it’s worth it for administrations to look into that.”

    Turning Point founder Kirk was a highly controversial political figure. His organization is notorious for its Professor Watchlist, an online database identifying “radical” professors. The watchlist has been called inaccurate, and has led to threats and harassment against faculty members across the country. It was also the reason why Point Loma Nazarene University in San Diego denied a third attempt by students to establish a school-affiliated Turning Point USA chapter last November.

    Some of Kirk’s most controversial comments include calling the Civil Rights Act “a huge mistake,” spreading COVID-19 misinformation and saying some gun deaths each year were worth it to protect the Second Amendment.

    In California, Generation Z, or those under the age of 29, is 1.5 times as likely to identify as liberal compared to their grandparents’ generation, according to a 2022 statewide survey conducted by the Public Policy Institute of California.

    This lack of conservatism among young people spills onto campuses. Only three California institutions are featured on a list published last fall by college-ranking website Niche of the 100 most conservative colleges in the country. The list is based on student reviews of the political leanings of their campus communities. All three California institutions are private universities: Biola, California Baptist and National.

    Creating red spaces in blue places

    Students founded a Turning Point chapter at Claremont McKenna last spring. After Kirk’s death in the fall, college security supervised each of the chapter’s events. Several students heckled a vigil they held after Kirk’s assassination in September. And at a February campus Turning Point tabling event, dozens of partially nude bikers rode by in protest of the national organization’s viewpoints.

    Bike protest organizer Luca Davis called Turning Point’s values “un-American,” and said the national organization’s harmful rhetoric should not be tolerated on campuses. A junior at Pitzer College, which is part of the Claremont consortium, Davis said he hoped that having dozens of students laughing and blasting music as they biked by the tabling event would act as a visible “foil” to Turning Point’s values.

    “We’re living our beliefs and values while they’re working to tear them down,” he said. “It’s an active expression of everything they’re trying to destroy.”

    Despite the pushback, a Turning Point student leader said that membership has grown substantially since Kirk’s death, and most members are underclassmen.

    A die-hard Floridian, 19-year-old Gabriel Khuly said he became disillusioned by Democratic politics after he moved to California to attend Claremont McKenna for college.

    “You really only get to see how stupid and bad Democrat policies are once you get to [really] see them,” he said, citing the high concentration of homelessness on Skid Row and high food prices.

    The self-described “gadfly” and well-known conservative on campus said he noticed his right-leaning peers often don’t feel fully comfortable sharing their views, both in and out of the classroom.

    “There is still a sort of desire… to at least partially conceal those views,” he said.

    Khuly has received a lot of flak for voicing his conservative political opinions on campus, particularly on the anonymous, campus-based social app Fizz. In late September last year, Khuly wore his MAGA cap and, alongside his friends, debated students on abortion and climate change at a table outside the campus dining hall. Later, a post on the campus app called him “the most insufferable, weird, and unf*ckable guy on the planet,” receiving over 1,500 upvotes.

    Khuly said “he could not care less” about the retaliation.

    “These sorts of people, they don’t exist in the real world,” he said. “They exist online, they exist on college campuses, they exist at bougie millennial coffee shops … they’ll block up the streets for traffic for some protest or whatever, but outside of that, they don’t exist.”

    Up north in Shasta County, voters aged 18 to 20 are more likely to register Republican than those aged 21 to 29. But Shasta College itself, according to Randolph, is still a liberal hotspot, where speaking against liberal viewpoints wasn’t really allowed — until his Turning Point chapter came along.

    “People have said that they’ve gotten a lot of relief now that they know we’re on campus.”

    In some instances, tensions have boiled over, like at Turning Point’s final tour stop at UC Berkeley in November. Fights broke out, with one man hospitalized after he was struck in the head. Police in riot gear arrested several people. In March, a heated exchange occurred at Cerritos College between Democratic congressional candidate Shonique Williams and Republican students and activists.

    Political conflict in the classroom

    Scott Waller is the chair of the Political Science Department at Biola University in La Mirada, which Niche calls the most conservative college in California — and the 24th most conservative in the nation.

    During both of Trump’s administrations, Waller said he has noticed an increased “anxiousness” in the classroom.

    “If a student expresses his or her displeasure with the current Trump administration, they will know that there are students similarly animated in a very virulent way to defend the Trump administration,” he said. “That creates some tension in class.”

    Yet, some educators relish in-classroom conflict. Stephanie Muravchik and other scholars across the Claremont Colleges analyzed millions of college syllabuses last year to see how professors teach about some of the most contentious subjects in academia, including the ethics of abortion and the Israel-Hamas war. They argued that only a small fraction of professors teach the full range of controversy in the classroom.

    Professors must build “more contention” into the classroom in order to encourage healthy intellectual debate, the Claremont professors wrote in an October online magazine op-ed.

    So, in sections of her “Introduction to American Politics” class, Muravchik runs simulations with students taking on characters across the political aisle on topics such as social media regulation and constitutional ratification.

    She builds the simulations to include prominent conservative characters such as Texas Attorney General Ken Paxton and FBI Director Kash Patel. While all of her students have fun taking on these roles, she noted that her “quietly conservative students” can choose them and feel like they have “equal play in the political conversation.”

    “They have fun fighting,” she said. “They get to argue in a civil way.”

    Freshman Ava Khansari was in Muravchik’s American Politics class last fall. She said she enjoyed the simulations, and found them eye-opening. In one simulation, as she took on the role of TikTok CEO Shou Chew in a debate on deregulating social media, Khansari said she realized her true viewpoints “went the opposite direction” to her character’s views.

    “The games were a lot of fun,” Khansari said. “I really did change my viewpoints on certain topics.”

    In a separate course on “American Jews and Liberal Democracy,” Muravchik allows a few tense class sessions where, in class discussions, students debate more right-wing perspectives as well as other views.

    “A number of students had some sort of revolution in their political thinking in all kinds of directions,” Muravchik said. After some particularly exciting debate, one student even “came out as conservative.”

    Claremont McKenna student Khuly was part of a course titled “Liberalism and Conservatism” at the college last fall, which explored political opinions over multiple centuries, and was, for the first time, co-taught by a left- and a right-wing professor.

    “I think that it allows the space for genuine, real study of politics,” he said. “You don’t get many spaces for that.”

    Despite these benefits, there is one thing Khuly would change.

    “I can’t believe I’m saying this, [but] I wish we read more [work by] liberals.”

  • ID'd in Los Angeles County this year
    A hand holds a small vial between its pointer finger and thumb. The vial says "single dose measles, mumps, and rubella virus vaccine" it has a blue cap. The background is blurred.
    Officials recommend checking your vaccination status if you were exposed to measles.

    Topline:

    The Los Angeles County Department of Public Health has confirmed its fifth measles case of the year. The person flew into LAX on Thursday, May 14.

    Why now: The resident was traveling internationally and arrived at Tom Bradley International Terminal (Terminal B) at LAX on May 14 via Alaska Airlines Flight 1354, departing from Guatemala City. Anyone in the terminal between 6 and 8 a.m. that morning may have been exposed.

    What's next: Public health officials say passengers seated near the infected traveler will be notified by their respective local health departments. They are working to find additional exposure sites that the traveler visited in L.A. County.

    What you should do: If you were at LAX during that time, officials say you should check your vaccination status.

    Those exposed could be at risk of developing measles one to three weeks after exposure. If you do develop symptoms of measles, officials advise you to call your doctor as soon as possible, and before going in, since it’s so contagious.

    Symptoms include: High fever, cough, runny nose, red and watery eyes, and a rash three to five days after other symptoms. 

    Vulnerable populations: If you’re pregnant, have an infant, have a weakened immune system or are not immunized, call your doctor right away after possible exposure, even if you don’t have symptoms.

    The bigger picture: According to the CDC, there have been 27 new outbreaks of measles across the United States this year, with 1,893 cases so far.

    In 2025, there were 48 outbreaks across the U.S., with a total of 2,288 confirmed cases. Nine were in Los Angeles County.

    Go deeper: Measles is back in California. Health departments are fighting it with less
