  • Scientist, tattoo artist team up for "smart ink"
    A long-haired man with light skin wearing glasses is sitting in a lab working with a jar of white liquid being poured from a machine. He's wearing blue latex gloves.
    Scientist Carson Bruns’ laboratory at the University of Colorado-Boulder makes tattoo inks by mixing, stirring, evaporating, and spinning a series of liquids until they end up with particles of dye encased in beads of plexiglass.

    Topline:

    Tattoos are more popular than ever. About a third of Americans have at least one. A scientist-entrepreneur, together with a celebrity tattoo artist, believes that ink could be doing a lot more.

    How so? It starts with a small dot that represents being able to turn a tattoo "off" or "on" depending on where you are. Nanoengineer Carson Bruns started a company with tattoo-artist-to-the-stars Keith “Bang Bang” McCurdy, along with a former doctoral student. Early next year, they plan to release their first product, Magic Ink, to a group of handpicked artists. The business partners have long-term hopes for smart tattoos that have a health value, but cosmetics are cheaper and simpler to get to consumers than medical devices. So, that’s where they’re starting.

    Read more ... to hear about this journey toward tattoos and tech.

    Mad-scientist kind of moments happen fairly often for nanoengineer Carson Bruns. A few months ago in his lab at the University of Colorado-Boulder, he tested his latest invention on his own arm and asked a colleague for help.

    “We were like, ‘OK, we’re going to tattoo ourselves. Can you help us today?’” he said.

    The tattoo is like a freckle, a little blue dot. But he can turn it on and off. Like the way a mood ring changes color with temperature, this tattoo changes with light: Ultraviolet light to turn it on, daylight (or even a flashlight) to turn it off.

    “You can go to court and turn it off, and then go to the party and turn it on. And then go to Grandma’s house and turn it off,” said Bruns, who is affiliated with the university’s ATLAS Institute, which prides itself on fostering out-of-the-box ideas.

    Bruns started a company with tattoo-artist-to-the-stars Keith “Bang Bang” McCurdy, along with a former doctoral student. Early next year, they plan to release their first product, Magic Ink, to a group of handpicked artists. The business partners have long-term hopes for smart tattoos that have a health value, but cosmetics are cheaper and simpler to get to consumers than medical devices. So, that’s where they’re starting.

    The new ink will enter a market in a moment of flux for the regulation of cosmetics. The FDA steps in to urge a recall if an ink causes a bacterial outbreak but traditionally has not exercised its regulatory might over tattoo ink products as it does with other products that go into the body. (Tattoo inks don’t even have to be sterile.) But following the Modernization of Cosmetics Regulation Act of 2022, the FDA is expanding its authority over tattoo manufacturers. The agency is now accepting comments on draft guidance about tattoo ink preparation.

    “To be honest with you, I don’t think either the FDA or the tattoo ink industry really knows what that’s going to look like,” said John Swierk, a chemist at the State University of New York-Binghamton. But, he said, the law does mean “the FDA has a new charge to really ensure that labeling is correct and good manufacturing practices are being followed.”

    Bruns said Magic Ink is made of particles of dye, encased in beads of plexiglass — the same polymethyl methacrylate material in those dermal fillers people use to plump their lips. Dermal fillers are FDA-approved, whereas tattoo ink contents can be like a black box.

    Swierk said many of the tattoo pigments in use now have been around a long time, which gives some users a base comfort level about their safety. But a new material comes with new unknowns.

    “If somebody is going to get tattooed with Magic Ink, they have to accept a degree of uncertainty about what the future is going to hold with that ink,” Swierk said.

    It’s $100 for a half-ounce bottle. That’s a lot more than regular ink costs. If the product takes off, the University of Colorado-Boulder will also benefit, as it owns the intellectual property.

    Bang Bang is among a few dozen people, many of them tattoo artists, who are already wearing the ink in their skin.

    Tattoo artist Selina Medina has been in the business more than 20 years and used to work for an ink manufacturer. She spends a lot of time advocating for tattoo safety, volunteering with several national and international groups focused on the issue.

    “I’d probably give it a year in the market before I would buy it. But it does look really interesting,” said Medina, who is on the board of directors for the Alliance of Professional Tattooists.

    Medina hopes this ink is different from the UV inks she saw pop up in the 2000s, which would glow under a black light.

    “It seemed like an awesome idea, but then we noticed that it faded really fast,” she said. “It would just disappear. We didn’t know what it did. We didn’t know where it went. And that was just kind of like, ‘What the hell is this stuff?’”

    She expects her customers will be clamoring for Magic Ink before she’s ready to purchase it.

    Looking further afield, some companies are already investing in technology embedded in the skin. A European company called DSruptive makes injectable thermometers. It said about 5,000 people — living primarily in Sweden, Japan, the U.S., and the United Kingdom — have had the devices installed. Ali Yetisen, an engineer at Imperial College London, said for companies eyeing tech embedded in the skin, diabetes is a big focus.

    “That’s where the money is. Most companies invest in this area,” said Yetisen. The dream is to create something like a tattoo that could measure blood sugar in real time, and be long-lasting, he said.

    “That’s the holy grail of all medical diagnostics,” he said.

    While Bruns’ inventions sense external factors like light and radiation, for manufacturers looking to develop in-body tech that reacts to the blood, there are other scientific hurdles. The immune system forms little shells around foreign bodies, effectively putting up a wall between a sensor and the blood.

    No one has really figured a way around that yet, said Yetisen, but a lot of people are trying.

  • Driver arrested on murder charges
    A heavily damaged SUV sits crushed against the side of an orange Metro bus at night.
    Police and LA Metro investigate the scene of a crash between an SUV and a LA Metro Bus that left three people dead on Tuesday in Chatsworth.

    Topline:

    A motorist was arrested on murder charges after authorities say she slammed her SUV into a city bus in Los Angeles, killing at least two people and injuring six others in a prelude to a second deadly tragedy: the fiery crash of a TV news helicopter that was covering the collision.


    About the bus crash: Bailee Lynn Rios, 36, of Simi Valley, was arrested Tuesday night and is being held at a Los Angeles jail with bail set at $4 million, police said Wednesday. Police say Rios drove her 2004 Ford Expedition the wrong way down a busy avenue, ran a red light and struck a vehicle before hitting the bus. One passenger was fully ejected from the bus and another was partially ejected, police said. The case is being forwarded to the district attorney’s office, which will decide whether to file the charges in court or pursue different ones.

    Helicopter crash: NBC4 Los Angeles reported that two people aboard the helicopter — reporter Eliana Moreno and pilot George Marciniw — were killed when the chopper went down Tuesday in the Chatsworth. A person on the ground, identified as 29-year-old Edy Gutierrez Mejia, died in a parking lot, the Los Angeles County Medical Examiner’s Office said. He was from Guatemala, the country’s consulate confirmed. The crash happened as news crews were reporting on the collision involving the SUV that slammed into the bus.

    LOS ANGELES (AP) — A motorist was arrested on murder charges after authorities say she slammed her SUV into a city bus in Los Angeles, killing at least two people and injuring six others in a prelude to a second deadly tragedy: the fiery crash of a TV news helicopter that was covering the collision.

    Bailee Lynn Rios, 36, of Simi Valley, was arrested Tuesday night and is being held at a Los Angeles jail with bail set at $4 million, police said Wednesday. The case is being forwarded to the district attorney’s office, which will decide whether to file the charges in court or pursue different ones. Information on a lawyer who could speak on her behalf was not immediately available.

    The helicopter, which was used by NBC and Telemundo, crashed about two hours after police say Rios drove her 2004 Ford Expedition the wrong way down a busy avenue, ran a red light and struck a vehicle before hitting the bus. One passenger was fully ejected from the bus and another was partially ejected, police said.

    Rios’ mother, Cindy Rios, said she was shocked and saddened by the string of events. She said she had not spoken to Bailee Lynn since her arrest and had not been contacted by law enforcement.

    “It’s just horrible,” Cindy Rios told The Associated Press in a phone interview Wednesday. “The fact that my daughter was involved and was the cause of it is just extremely disturbing.”

    “If anything, I’m sorry for the other families,” she added. “My daughter’s alive. People lost their lives.”

    Chopper crash killed a reporter, a pilot and a man on the ground

    NBC4 Los Angeles reported that two people aboard the helicopter — reporter Eliana Moreno and pilot George Marciniw — were killed when the chopper went down Tuesday in the Chatsworth neighborhood in the San Fernando Valley north of downtown.

    A person on the ground, identified as 29-year-old Edy Gutierrez Mejia, died in a parking lot, the Los Angeles County Medical Examiner’s Office said. He was from Guatemala, the country’s consulate confirmed.

    The crash happened as news crews were reporting on the collision involving the SUV that slammed into the bus.

    There were no immediate details on what caused the helicopter crash, but an alarm could be heard sounding inside the helicopter’s cockpit as it lost altitude in the final seconds of video the crew broadcast before the crash.

    Just after the beeping noise starts, a woman’s voice says “uh oh.” The helicopter moves quickly away from the bus crash site and starts losing altitude. The woman says “You can’t pull up?” before the video stops as the chopper nears the ground.

    “That video is probably the most important evidence that we have discovered so far,” National Transportation Safety Board investigator Fabian Salazar said Wednesday at a news briefing.

    Salazar said the sounds were consistent with the helicopter’s engine changing speed, as well as what he said were likely advisory tones for the pilot. The NTSB said it is also investigating the bus collision.

    The helicopter, a Eurocopter AS350, went down near a large storage facility. At least four cars and two storage containers burned after the helicopter caught fire. NBC4 reporter Robert Kovacik was at the bus scene and saw black smoke and rushed to the helicopter crash site.

    Anchor and reporters pay tearful tributes to deceased colleagues

    Moreno was a familiar voice for NBC4 and Telemundo 52 during the station’s aerial coverage. She and Marciniw were both were employees of Angel City Air, which operated the chopper for the station.

    Moreno, born in Orange County, joined Angel City Air in 2010, the same year she earned a broadcast journalism and political science degree from Chapman University. She reported for several news outlets and began flying with Marciniw in 2023, the NBC4 website said.

    Marciniw grew up in Southern California and graduated from Burbank High School in 1974.

    “I think a lot of us are still trying to process what happened, this terrible loss,” NBC4 reporter Lauren Coronado told viewers early Wednesday as she stood near the crash site. A hazmat crew was cleaning up jet fuel, she said.

    In a tribute to Moreno and Marciniw, the newscast referred to them as “the team in the sky,” saying Moreno would often post videos from her job and was in awe of the view. Anchor Lynette Romero held a colleague’s hand and wiped away tears after hearing Moreno’s voice when one of her posts was played.

    In an interview with the station, Esteban Jimenez, a pilot, said he had known Marciniw since the 1990s. He said Marciniw had been his instructor.

    “I just talked to him on Sunday. We were talking about the aviation business and retiring,” he said.

    Expert talks about what may have caused the crash

    Aviation safety expert Jeff Guzzetti said the alarm sounding in the helicopter’s final video sounds like the low rotor RPM warning horn that signals the main rotor is no longer spinning enough to keep the helicopter in the air.

    “It just has all the earmarks of a potential loss of engine power and a dangerous decrease in the main rotor speed,” said Guzzetti who used to investigate crashes for both the NTSB and FAA.

    Guzzetti said the pilot appeared to be trying to perform an emergency maneuver to use the wind to force the rotor to spin again much like a breeze turns a windmill. Doing that can create a bit of lift that could help cushion the impact, but Guzzetti said there would have been little opportunity to do that because the helicopter had been hovering at a low altitude beforehand.

    There are risks to news helicopters particularly in a major city like Los Angeles where multiple helicopters respond to an incident, but the pilots all coordinate closely over the radio to ensure they maintain a safe distance from each other. The industry also shares best practices to help keep these news flights safe.

    “It’s a very unique form of flying. And the community is very good about lessons learned,” Guzzetti said. “And so because of that, you don’t hear about too many of those accidents. So they’re rare, but they do occur, just because the mission is a risky one.”

    Other crashes involving news helicopters

    The station said this is the second aviation tragedy in its history.

    In 1977, a KNBC news helicopter crashed when it ran out of fuel while returning to the station after covering a wildfire in Santa Barbara, killing the pilot and camera operator. The pilot, former U.S. Air Force officer Francis Gary Powers, had been in the news years earlier when he was shot down and captured while flying a U-2 spy plane over the Soviet Union for the CIA, an ordeal portrayed in the movie “Bridge of Spies.”

    There have been at least eight fatal crashes involving news helicopters in the U.S. since 2000, killing 16 people, according to a review of federal accident records and news accounts.

    They include a 2023 crash in a New Jersey forest that killed the pilot and a photographer aboard a helicopter used by Philadelphia station WPVI and a 2022 crash beside a Charlotte, North Carolina, interstate that killed a pilot and meteorologist during a training flight for WBTV.

    A 2007 midair collision in Phoenix of two TV news helicopters that were covering a police chase led the NTSB to recommend that news helicopters have at least two people in the cockpit so the pilot can focus on flying while the reporter focuses on the story.

  • Prosecutors allege failures to oversee contractors
    A man in a suit stands in front of wood paneling and government seals.
    Federal prosecutor Bill Essayli, seen last month, said Wednesday that when it came to homelessness spending in L.A., "nobody was minding the shop."

    Topline:

    Federal and county law enforcement announced charges Wednesday against three people in their widening investigation of homelessness fraud in the L.A. area. Prosecutors said they plan to bring “many more” cases.

    ‘Ghost’ clients: Authorities alleged a bribery scheme built on "ghost" clients illustrates a deeper problem: For years, virtually no one was checking whether homeless services money was doing what it was supposed to do. "There's no vetting. There's no auditing. There's no accounting,” the top federal prosecutor in L.A. said Wednesday. “It was just a rush to push as much money out the door."

    Nightclub allegation: Authorities announced the arrest of Michael Young — founder of the Culver City nonprofit Home At Last — and accused him of using shell companies and fake bids to siphon $1 million in taxpayer money into a high-end nightclub, a nearly $50,000 trip to Tahiti and a $140,000 restoration of a vintage Chevy Impala. About $12 million in misappropriated funds — almost all of it by Young — is alleged in the new cases.

    Read on … to learn what a federal prosecutor had to say about the leaders of L.A.’s homeless services agency.

    Federal and county law enforcement announced charges Wednesday against three people in a widening investigation of homelessness services fraud in the L.A. area. Prosecutors previously charged three other people and said they plan to bring “many more” cases.

    In Wednesday’s announcement at a news conference, authorities alleged a bribery scheme built on "ghost" clients illustrates a yearslong problem.

    "Nobody was minding the shop," the region’s top federal prosecutor, Bill Essayli, told reporters in response to a question from LAist. "There's no vetting. There's no auditing. There's no accounting. It was just a rush to push as much money out the door."

    What are the charges?

    Authorities arrested Michael Young — founder of the Culver City nonprofit Home At Last — and accused him of using shell companies and fake bids to misappropriate $12 million in taxpayer funds. The allegations include siphoning $1 million into a high-end nightclub, a nearly $50,000 trip to Tahiti and a $140,000 restoration of a vintage Chevy Impala.

    Scott Turner, the U.S. secretary for Housing and Urban Development, said Young's group received more than $118 million in public dollars for homeless housing since 2019 — over $75 million of it through the Los Angeles Homeless Services Authority, or LAHSA.

    The new cases allege about $12 million in misappropriated funds — almost all of it by Young.

    The bribery charges are against Lakiya Malone, an employee of the nonprofit Special Service for Groups, or SSG, who was responsible for referring homeless people to LAHSA-funded housing. Prosecutors say Malone took roughly $180,000 in bribes from Alexander Soofer, head of the now-defunct nonprofit Abundant Blessings, and in exchange steered him "ghost" participants — so he could bill for services never rendered.

    “She was supposed to guard the money, and instead she took bribes,” Essayli, the first assistant U.S. attorney for the Central District of California, said.

    In a statement, SSG said it has been working with federal prosecutors “to ensure that any responsible individuals are held accountable” and has strengthened its “protocols and compliance.”

    Charges against Soofer were announced in January. Authorities announced Wednesday that he has agreed to plead guilty to wire fraud and money laundering. Soofer admitted in his plea agreement to the alleged bribery scheme.

    According to prosecutors, Soofer also admitted to "pocketing at least $2 million in taxpayer money for his own personal enrichment and for businesses unrelated to homeless housing," and that he has agreed to forfeit the money to the U.S. government. Prosecutors previously alleged he diverted a much larger amount: at least $10 million.

    An LAist investigation found LAHSA kept awarding millions in contract renewals to Soofer’s group even after LAHSA’s own compliance team labeled it "high-risk" for, among other things, billing for services while reporting no enrolled participants.

    The third defendant announced Wednesday is Donye Mitchell of the nonprofit Big Blue Umbrella. Mitchell is accused of lying about his experience to land a $1.2 million county-funded grant, receiving $315,000 and using those funds for personal expenses, including bail for a domestic violence arrest and video games. Officials said he's believed to be in Las Vegas and hadn’t been arrested as of Wednesday morning.

    Mitchell is “a convicted fraudster, by the way,” Essayli said. He was convicted in 2011 of defrauding California unemployment benefits, according to the criminal complaint in the new case, and was ordered in 2012 to compensate the state $6 million.

    The county funds he’s accused of stealing were awarded by a county vendor in 2024 — well after his fraud conviction.

    LAist has left phone messages for Young's and Malone’s lawyers inviting their response to the charges and will update this article if they respond. It is unknown if Mitchell, who has not yet been arrested, has a lawyer.

    Prosecutors' critique 

    Essayli and L.A. County District Attorney Nathan Hochman criticized what they called a glaring lack of oversight of massive spending on homeless services. Hochman cited a court-ordered 2025 report that found L.A. city officials failed to properly track $2.3 billion in homeless funds, largely by outsourcing to LAHSA — which the review found failed to collect accurate data on its vendors and hold them accountable.

    "We have not seen the results you would expect for billions of dollars being spent," Hochman said.

    “This is the beginning of these prosecutions,” he added.  ”Many more” are expected in the coming months, he said.

    Continuing trouble for LAHSA 

    The new charges were announced the day after LAHSA's governing commission decided to give up its responsibility for federal dollars, including applying for roughly $240 million a year in federal homelessness funding and running the annual homeless count.

    Also on Tuesday, Mayor Karen Bass skipped a congressional hearing on LAHSA's fraud problems, calling it a "politically motivated" attack.

    LAHSA, now led by Interim CEO Gita O'Neill, said in a statement Wednesday that it has "zero tolerance for fraud, waste, or the exploitation of public resources" and commended prosecutors’ action.

    The agency said it terminated its contracts with Young’s nonprofit in June after evidence of wrongdoing emerged, and is pursuing recovery of cash seized from Young. The statement added that LAHSA fully cooperated with the federal task force and that no LAHSA staff are implicated — only "external provider executives and outside contractors.”

    Essayli was asked Wednesday whether LAHSA's past or current leadership has been culpable.

    "That's actually a very difficult question to answer," he said.

    "It is not against federal law to be incompetent, unfortunately. I wish it were,” Essayli said. “So just because the people at the helm did not do a good job, that does not give us the authority to arrest them."

    “ I assure you, if anyone in power engaged in violation of federal law, we will not hesitate to charge them.”

  • Local activists had sought to meet with her

    Mellody Hobson and George Lucas speak onstage during the preview of the now-open Lucas Museum of Narrative Art on Sept. 03, 2026. Hobson said this week she is stepping down from the LA28 Olympic committee.

    Topline:

    Mellody Hobson, businesswoman and Lucas Museum co-founder, has stepped down from the LA28 Board of Directors, LA28 confirmed to LAist today.

    The details: In an email reviewed by LAist, Hobson said that the demands of steering the newly-opened Lucas Museum were too great to continue serving on the 35-person board, which is led by Casey Wasserman.

    The context: The move comes after pressure from local activists who sought to meet with Hobson to raise their concerns about the Olympics and Paralympics, including how the Games would affect South Los Angeles where the Lucas Museum is located.

    Mellody Hobson, businesswoman and Lucas Museum co-founder, has stepped down from the LA28 Board of Directors, LA28 confirmed to LAist Wednesday.

    In an email reviewed by LAist, Hobson said that the demands of steering the newly-opened Lucas Museum were too great to continue serving on the 35-person board, which is led by Casey Wasserman.

    The move comes after pressure from local activists who sought to meet with Hobson to raise their concerns about the Olympics and Paralympics, including how the Games would affect South Los Angeles where the Lucas Museum is located.

    Reverend Gary Bernard Williams, a pastor in South L.A., told LAist late last month, weeks before the news of her departure, that he believed “she could be a person that could be a counterbalance to the other members of the committee that really do not have the same kind of care and concern for what happens to our people.”

    Williams, a member of a coalition of labor and community groups called the Fair Games Coalition, said he saw Hobson as the group’s best shot at influencing the LA28 Board, which includes a number of allies of President Donald Trump as well as some city appointees.

    Hobson did not respond to a request for comment in time for publication.
