On summer mornings, local kids like to gather at Padaro Beach in California to learn to surf in gentle whitewater waves. A few years ago, the beach also became a popular hangout for juvenile great white sharks.

That led to the launch of SharkEye, an initiative at the University of California Santa Barbara’s Benioff Ocean Science Laboratory (BOSL), which uses drones to monitor what’s happening beneath the waves.

If a shark is spotted, SharkEye sends a text to the 80-or-so people who have signed up for alerts, including local lifeguards, surf shop owners, and the parents of children who take lessons.

In recent years, other initiatives have seen officials and lifeguards from New York to Sydney using drones to keep beachgoers safe, monitoring video streamed from a camera. That requires a pilot to stay focused on a screen, contending with choppy water and glare from the sun, to differentiate sharks from paddleboarders, seals, and undulating kelp strands. One study found that human-monitored drones only detect sharks about 60% of the time.

SharkEye – part research program, part community safety tool – is using the video it collects to analyze shark behavior. It’s also feeding its footage into a computer vision machine learning model – a type of artificial intelligence (AI) technology that enables computers to glean information from images and videos – to train it to detect great white sharks near Padaro Beach, close to the city of Santa Barbara.

“Automating shark detection … can (also) be really helpful for a lot of communities outside of ours here in California,” Neil Nathan, a project scientist with BOSL, who graduated from Stanford University with a master’s degree in environmental studies a few years ago, told CNN.

A rise in the popularity of drones, and the proliferation of social media, may make it seem like sharks are everywhere. It doesn’t help that warming ocean temperatures are pushing sharks into new habitats, and that juvenile great whites, which can grow to about eight to 10 feet long, like to hang out near the shore, making them more visible to beachgoers.

Yet shark attacks are rare. In 2023, 69 people globally were at the receiving end of unprovoked bites – which is in line with the average of 63 annual incidents between 2018 and 2022. Just 10 of them died, according to the Florida Museum of Natural History’s International Shark Attack File.

Although there hasn’t been a fatal attack recorded at Padaro Beach, some community members were concerned when sharks began loitering there.

That’s why SharkEye has been regularly running drone flights to monitor the coastline for about five years, once spotting 15 juvenile great white sharks in a single day.

Early tests indicate that the AI technology is already performing “incredibly well,” detecting most sharks a human can, and sometimes sharks that a human missed, perhaps because it was swimming too deep to spot easily, said Nathan.

This summer, the project began field testing its technology by pitting drone pilots against AI. Its pilot surveys the area and counts the number of sharks she spots. Then SharkEye’s model analyzes the video to see how many sharks it can find.

Today, the community alerts are based on human analysis. If all goes swimmingly, those reports may become AI-assisted – with manual monitoring and checks – by the end of the season, or the start of next summer, said Nathan. In the future, the process may even become totally automated, making it faster and potentially more accurate.

AI and wildlife

AI technologies are being harnessed in myriad ways to mitigate human-wildlife conflict. In India, AI-enabled cameras are alerting villagers when tigers are closing in on their livestock, and in Australia, technology is being used to manage some of its dangerous creatures.

Ripper Corp and academics pioneered what they say are the first shark identification algorithms in the world, which were put to use in drones a few years ago. The latest version of the software is being tested across the Australian state of Queensland, Mexico and the Caribbean to detect sharks and crocodiles.

However, AI is not yet used widely for shark detection. Surf Life Saving New South Wales, which protects dozens of beaches along the state’s coast, including Sydney’s iconic Bondi Beach, uses drones in 50 locations. But a spokesperson told CNN that their drones aren’t currently utilizing AI.

A group from one Australian university that worked on AI-enhanced shark-spotting tools wrote in 2022 that the technology can struggle when encountering conditions that weren’t present in the training data.

SharkEye plans to make its model free and available for researchers to amend or build on, and to create an AI-powered app that’s easy for people like lifeguards and drone hobbyists to run their footage through. That could help keep people safe, but also allow humans to better understand and protect sharks.

Nathan said it remains to be seen how much retraining will be required for SharkEye to expand to other locations. He’s hopeful that if drone pilots fly at the same speed and altitude, they won’t have too many issues elsewhere in California, where the coastline is similar.

Officials in Honolulu said this month that they’re considering launching a drone shark surveillance program, according to local media. If SharkEye’s technology were to be used in places like Hawaii, where tiger sharks are the biggest concern, and the hue of the water differs, more retraining might be necessary. But Nathan said that SharkEye is open to working with other localities to help adapt the model.

“Communities want to have that knowledge and that awareness so it’s easier to more safely share the water with these creatures,” said Nathan. “Sharks are an incredible species that we still are always learning new things about.”

California Islamic calligraphy artist preserves ancient tradition during Arab American Heritage Month


As Arab American Heritage Month is celebrated, one Northern California artist is keeping the centuries-old tradition of Islamic calligraphy alive, one carefully measured stroke at a time.

Sehar Shahzad is a student calligrapher. Before starting any project, Shahzad said “one of the first things that calligraphers learn is how to cut their pens.” 

Her tools must be in pristine condition.

“Your instruments are just as important as anything else in this art,” she said.

Shahzad said that as a young girl growing up in Toronto, she took up Islamic calligraphy while reflecting on her religion.

“It’s not like I’d never seen it before, but it was my first time kind of trying it,” she said. “And there’s no other way to say it except that I just fell in love with it.”

Now married with three children, Islamic calligraphy is very much part of her life.

“I remember thinking that this isn’t something that I just want to learn for fun,” she said. “I really want to be able to master it.”

Shahzad said that every angle and curve follows strict geometric rules and is measured with dots.

“For example, this letter here was just a little bit too long, so we use these nuqtas to help us guide and understand how long that letter should be,” she said.

Like the Arabic language, Islamic calligraphy is read from right to left. Its bold simplicity requires precision and a deep understanding of proportion.

“When you’re creating a composition, it’s not only about the letter itself,” Shahzad said. “It’s about composition as a whole and making sure that everything balances together.”

Even though she’s still mastering her form, Shahzad’s work is featured in the prayer room of a Muslim cemetery in Napa and in the domes of mosques in San Jose, Hayward, and San Francisco.

Still, she considers her work on paper the most special.

“A form of meditation, a form of worship, requires focus, requires discipline, really brings me to a different space,” Shahzad said. “And I think that’s what I love most.”

Proving that in this fast-paced world, this millennia-long tradition is far from disappearing.

Shahzad’s work will be featured at the upcoming Light Upon Light art exhibit at the Tarbiya Institute in Roseville from April 24-26.

California sees lowest number of firearm-related deaths since 1968, new data shows


LOS ANGELES (KABC) — California Attorney General Rob Bonta on Tuesday highlighted what he called historic progress in the state’s fight against gun violence.

“California has achieved something historic with the lowest rates of firearm deaths, suicides and homicides on record,” he said during a press conference.

According to Bonta, in 2024, California saw the lowest numbers of firearm-related deaths since 1968. That also drove the state’s overall homicide rate to its lowest level on record in Centers for Disease Control and Prevention data, Bonta’s office said.

However, Bonta warned lawmakers that those gains could be at risk without continued investment.

“This progress is fragile,” he said. “It was driven in part by significant investments that are now declining or disappearing, and without continued and increased investment, we risk losing it.”

Bonta urged policymakers to continue advancing gun violence prevention efforts and education initiatives.

California lawmaker introduces bill to protect wildlife from euthanasia, create coexistence program

California lawmaker introduces bill to protect wildlife from euthanasia, create coexistence program


A Southern California state senator has proposed a new law that would prevent euthanasia in the state’s wildlife just a month after a mother bear was put down for swiping at a woman in Monrovia, feet away from where her two cubs were located. 

The legislation, SB 1135, which was introduced by Sen. Catherine Blakespear (D-Encinitas), calls for the establishment of a state program that promotes the coexistence with wildlife and codifies a wolf-livestock coexistence and compensation program. The move comes two years after funding for a similar wildlife coexistence program expired. 

“We can and must responsibly support people and wild animals to exist in a California where we are all under growing pressures and cumulative threats like extreme heat, frequent drought and intense wildfires that animals respond to by moving in search of resources to survive,” Sen. Blakespear said in a statement. “That means investing in science-based, situation-specific, proactive strategies to minimize negative interactions and prevent escalation to conflicts that pose risks for people and animals. SB 1135 proposes a program to better protect people, wildlife and communities.”

The proposed coexistence program, which would be allocated nearly $50 million through the state’s 2026-27 budget, would build on the previous version, which deployed trained regional human-wildlife conflict staff around the state. The absence was noted by CDFW leaders during a state Assembly meeting in January, according to Blakespear. 

“Over the last five years, wildlife incident reports logged by the California Department of Fish and Wildlife (CDFW) increased by 31 percent and calls, emails and field contacts rose by 58 percent,” Blakespear’s proposal says. 

She noted the recent headline across the state, including “Blondie,” the Monrovia mother bear who was captured and put down by wildlife officials in March after it swiped at a woman near the home it was living under with its two cubs

The home in question belongs to Richard Franco. He, along with many other Monrovia residents, has documented his encounters with bears over the years, even setting up a system of trail cameras to track the bears’ movements. 

“Getting to know her, you could see what a devoted mother she was,” Franco said. “She was always building a nest.”

Franco and many of his neighbors were angered upon learning that CDFW officials had euthanized Blondie after her capture, which they credited to the fact that she had swiped at the woman days earlier and another person in 2025.

“Forcing them out, and then euthanizing the mom was just traumatic for us,” said one Monrovia couple. “It was just tragic, and there was no need for it; it was completely unnecessary.”

Situations like this are what caught Blakespear’s attention, leading to her proposal last week. 

“It is really my desire to make sure that wild places stay wild, and not be having to resort to lethal measures like killing bears or killing wolves,” Blakespear said, while speaking with CBS LA. “We need to have a program that is up and going so we can be educating people.”

The program calls for focus on public education, maintaining a statewide incident reporting system and deploying devices like barriers, noise and light machines and other technology that would deter predators from places where they shouldn’t be.
