The juvenile minke whale had been spotted swimming around San Francisco Bay for nearly a week by the time she beached herself off the coast of Emeryville on April 8. Scientists had thought she seemed healthy, but after an examination, they determined she was acting abnormally and had to be euthanized due to illness.

It was the fourth whale death in the San Francisco Bay in a week and a half. The other three were gray whales, the first of which—a 36-foot-long female—washed up at Black Sands Beach in the Marin Headlands on March 30. Its cause of death remains unknown.

On April 2, a deceased adult male gray whale was found floating east of Angel Island; its cause of death is also not known, according to the Marine Mammal Center. Then, a subadult male gray whale washed ashore at Fort Point Rock Beach near the Golden Gate Bridge in San Francisco on April 4, and scientists determined that it likely died due to a vessel strike, according to the mammal center.

Taken together, the deaths have raised the specter of past “unusual mortality events” that caused whales to die in higher-than-normal numbers.

“This is unusual,” said Kathi George, director of Cetacean Conservation Biology at the Marine Mammal Center in Sausalito. “It takes me back to several years ago when we did have a large number of strandings happen at the same time.”

While the unusually high number of whales beaching in such a short span is abnormal, the number of whales who have died around the bay for the year has remained in line with typical levels, scientists say.

“This is the normal time of year when gray whales are doing their northward migration from Mexico up to Alaska, so it’s not uncommon for us to have gray whales in and around San Francisco Bay in April and May each year,” said Moe Flannery, who leads the marine mammal necropsy team at the California Academy of Sciences.

“Although they seem high because they’re concentrated into a short period of time, the numbers of dead and stranded are not any different than the recent previous years.”

Whales can die for “a number of reasons”—from diseases to malnutrition to vessel strikes, George said.

“It’s coincidental that everything happened in a week and a half, but there are a lot of whales out there right now, and some of their physical condition that they’re in when they arrive in the bay may make them more susceptible to human impacts if they’re not as healthy,” she said.

Scientists began observing whales entering the San Francisco Bay around 2016 as they completed their annual migration between Mexico and the sub-Arctic, George said. The whales do not feed while they are in their breeding grounds in Mexico, and expend a lot of energy mating, nursing babies and giving birth before facing a long journey back north to their feeding grounds, she added.

Because of this energy expenditure, scientists have seen the gray whales attempt to feed in new locations—including San Francisco Bay, George said. Their increased appearance in the bay could also potentially be explained as whales seeking a place to rest before continuing the migration, or a reaction to climate change, warming ocean temperatures and prey availability.

The Marine Mammal Center has tracked at least 18 individual whales swimming in the bay this year, and sightings of gray whales have been reported almost every day since mid-March, George said. The majority of the whale sightings have been reported east of Angel Island, said Giancarlo Rulli, the associate director of public relations for the Marine Mammal Center.

Between 2019 and 2023, gray whales were dying in much higher numbers due to an unusual mortality event, which was declared by the National Oceanic and Atmospheric Administration Fisheries. Gray whales lost more than 40% of their population in four years, Rulli said. During this time, there were 347 gray whale strandings in the United States, according to NOAA.

“These whales basically left the Arctic with a half tank,” Rulli said. “The food sources that they were normally accustomed to eating that were highly nutritious for this massive, 10,000–12,000-mile journey, had moved farther away due to climate change, and as a result, these whales were left to forage on food matter that was much less nutritious.”

Between January and April 2019, which was the first year of the unusual mortality event, 34 dead gray whales washed up on California’s coast, Flannery said. Seven have so far this year.

George said that whether the recent deaths could be the start of an unusual mortality event is “still under discussion and review,” adding that the data collected from these strandings will help scientists understand “the bigger picture of what’s happening.”

“We’re not there yet,” she said, adding that scientists have to look at their migratory range holistically.

Whales will continue to appear in the bay through mid-May as they continue their migration north, George said.

Flannery added that anyone using the water “needs to be more aware of the animals that are sharing that environment.”

A Leak of San Francisco Police Drone Footage Exposes the New Reality of Urban Surveillance

A Leak of San Francisco Police Drone Footage Exposes the New Reality of Urban Surveillance


Just after noon on a Saturday last month, a Skydio X10 quadcopter hovered about 200 feet over a San Francisco apartment complex, watching police chase a man hiding behind a parked car. The target of this manhunt lay down on the pavement, apparently unaware that he remained in full view of the flying eye overhead. The 5-pound drone had, in fact, already followed him across the city, zooming in on his black SUV’s license plate, keeping the vehicle locked at the center of its video frame until he pulled over. Now it watched the police as they closed in and surrounded him.

As the officers approached, the man adjusted his hiding spot, moving to the other side of the parked car. At that moment, however, another Skydio drone zoomed in on his location, one of four Skydio quadcopters that had followed the man in just the prior hour. This one had been called away from a nearby McDonald’s, where it had been watching two people who’d exited the suspect’s car a few minutes earlier—and now began watching him from a second angle.

Within seconds, three officers converged on the man, two pointing weapons at him, then tackled him as half a dozen more police arrived on the scene. Police records provided to WIRED by the San Francisco Police Department show the entire street-and-sky response followed from what the SFPD described as an alleged “auto boost/strip” incident—the suspected theft of car parts or another object from a vehicle.

Drone footage exposed at a public web address shows how a quadcopter zoomed in on an SUV’s license plate, tracked it through traffic, then followed the driver as he exited the car and ran into an apartment complex. The suspect hid behind a vehicle, then adjusted his hiding place, yet was still visible to a second drone that arrived on the scene—one of four that tracked his location in a single hour and then captured police tackling him—all in response to what the SFPD describes as an alleged “auto boost/strip” incident, the theft of car parts or another object from a vehicle.

This glimpse of modern drone-enabled police surveillance, including the highly sensitive video of the man’s physical takedown, wasn’t voluntarily released by the SFPD—which, like most US police departments, rarely releases drone videos even in response to public records requests. Instead, it was accidentally livestreamed onto the open internet via Skydio’s website. That’s where two security researchers, Sam Curry and Maik Robert, discovered that the SFPD was leaking all of the real-time footage from five of its surveillance drones, including both color and thermal imaging, accompanying location metadata, and the drone pilots’ names and email addresses, to anyone who merely found the public web address where the videos were hosted.

Curry and Robert say they reported their discovery to Skydio around two days after discovering it, and it was quickly taken offline. By then, though, the researchers had watched police carry out what appeared to be multiple arrests and searches as well as tracking cars and individuals from the sky, all visible at a fully public web address.

“There’s a certain trust given to the police to use these things correctly,” says Curry. “When you’re watching a drone feed live, you can look into dozens of different apartments, you can see police zooming in on people, you can see arrests. The fact that all of this was exposed feels like a really big issue from a privacy perspective.”

The leaked feed of video captures two forced detentions—whether any actual arrests were made is unclear from the footage—a police visit to an apartment in a high-rise apartment building, and an apparent search of an alley populated with homeless people, as well as numerous other more ambiguous instances where police used drones to surveil individuals, vehicles, or buildings. While the feed remained live, Curry and Robert began archiving the public stream of data and videos and later shared the results with WIRED.

The archive Curry and Robert captured offers a detailed record of SFPD drone operations over about 48 hours in mid-June. It includes 60 videos from 20 separate flights, with each mission recorded from three feeds: a color camera, a thermal camera that renders people as heat signatures, and a third view from the drone’s rooftop dock. WIRED analyzed all 20 color videos with software that detects people, vehicles, and other objects in images. The review found that the cameras had filmed hundreds of people and vehicles across the 20 flights. In a single frame, as a drone hovered over a downtown intersection, the software counted 34 people crossing the street or standing on the sidewalks. Across all of the videos the footage showed clear faces of dozens of people.

Together, the videos amount to more than three hours of aerial color footage and roughly the same amount of thermal footage. The archive also includes second-by-second telemetry logs for every flight—more than 5,000 GPS points in all tracing over some 44 miles—recording each drone’s latitude and longitude, altitude, speed, heading, and battery level from takeoff to landing. Six SFPD pilots’ names and email addresses also appear across the logs.

I’m a writer who left LA for an AI startup in San Francisco. It was like stepping into a whole new world.

I’m a writer who left LA for an AI startup in San Francisco. It was like stepping into a whole new world.


I moved from Los Angeles to San Francisco because of a cold DM on X.

I grew up in the LA suburbs, and after attending college there I built my career in journalism across the country, first covering local news, and then crypto. I liked my comfortable life with friends and family.

Then in February, the chief of staff at Corgi, the AI insurance startup that recently went viral for its seven-day workweek, messaged me on X to ask if I would be interested in a role. I’d never heard of Corgi, but I’d seen a lot of people in crypto pivot to the AI industry and wanted to check it out.

A week later, I flew to San Francisco to visit the team, and in March, I joined them as their Head of Brand. My entire life changed in an instant.

Moving from Los Angeles to San Francisco felt like stepping into a completely different value system

In San Francisco, there’s a strong sense that AI is transforming the city and a level of intensity that I don’t think people outside the Bay Area fully appreciate. Everyone here believes they’re early to something massive.

Everyday, I meet people who’ve moved across state and city lines to work at startups in San Francisco. Like me, they’re willing to make extraordinary sacrifices for the possibility of being part of the next OpenAI or Anthropic.

In LA, one of the first questions people would ask me at events was, “What’s your Instagram?” Conversations often orbited around who you knew, what parties you were invited to, and how well you’ve curated yourself online.

In San Francisco, online curation still matters, but in a different way. People ask for your LinkedIn or X account. Or sometimes they skip social media entirely and ask, “What are you building?” Nobody seems particularly interested in whether you’re fashionable, attractive, or influential online. The currency is ideas, fundraising, and products.

Neither city is better; they optimize for different things. For now, I’m happy to be working with my head down in San Francisco, where I’m more productive and motivated than I was in LA.

My journalism background was more valuable than I expected

Coming from journalism, I assumed I’d be the least technical person in almost every room.

When you think of Silicon Valley, you think of engineers and founders who’ve raised millions of dollars. Conversations move quickly from product roadmaps to fundraising. At times, I wondered whether someone with an entirely different skillset really belonged in this environment.

Over time, I realized I was wrong. In the age of AI, companies compete on narrative, taste, and making people care. Storytelling is becoming infrastructure. OpenAI has highlighted the enormous opportunity for new forms of creative and narrative work emerging alongside AI, while hiring roles dedicated specifically to shaping the stories that help executives and customers understand the technology.

Rippling is hiring a Head of Storytelling to build its editorial voice and point of view, and Notion now has an entire Storytelling function within the company. In a world where everyone has access to the same models, the advantage increasingly belongs to the people who can synthesize ideas, understand culture, create meaning, and tell compelling stories. The humanities aren’t becoming less valuable in the AI era, they may be becoming more valuable than they have been in decades.

Since journalists can identify what matters in a sea of information and explain complicated topics clearly, my experience is incredibly useful for writing, editing, and shaping content about Corgi’s brand.

Changing industries doesn’t always mean leaving behind the skills you love most. Sometimes, it means finding a new way to use them.

I’m glad I moved despite the emotional trade-offs

I still miss many things about Los Angeles, like being close to my family, familiar neighborhoods, and the comfort of a city where I always knew the best spots to meet friends for coffee. LA shaped who I am, and I don’t think anywhere will ever replace it.

But moving to San Francisco has stretched me in ways staying comfortable never could have. I didn’t just change address, I moved into an entirely different world. I’m surrounded by people who genuinely believe they’re living through one of the most consequential technological shifts of our generation.

Whether history proves them right remains to be seen, but as a journalist used to documenting periods of change from the outside, I’m glad I’m experiencing this defining moment where the action is happening.

Like many others, I’m willing to uproot my life to be part of this once-in-a-lifetime shift. Even with the uncertainty, long hours, and emotional trade-offs that came with leaving my life in Los Angeles behind, I’m grateful I said yes to that cold message on X.
