Friends,

One litmus test for me of potential presidential candidates in 2028 is how many people ask me if a particular person has a chance of winning. I doubt they’d ask unless they supported that person. So when lots of people start asking about someone, I begin to take that person seriously.

Over the past month, the person who’s jumped to the head of the line in these sorts of questions is Rep. Alexandria Ocasio-Cortez. Most of the people who ask me about her are under 30, and they’re hugely enthusiastic about her.

Before I give you my response, let me say something about the person in American politics she’s most associated with — Bernie Sanders — and the organization she’s most identified with — the Democratic Socialists of America.

Bernie

I’ll say it straight out: I love Bernie. For years now, he’s been leading all of us into the future. He’s given progressives a clear direction.

I love his authenticity. Some people like Trump because he says whatever he wants, but he’s an asshole. Bernie’s authenticity comes from saying what he wants and speaking the truth. Although Bernie is blunt, when he growls “this grotesque level of income and wealth inequality is immoral,” he means it. And he’s right.

I love his chutzpah. Bernie once announced that Starbucks’s anti-labor CEO Howard Schultz had agreed to testify before the Senate Committee on Health, Education, Labor and Pensions, which Bernie chaired, because he had threatened him with a subpoena if he didn’t. The National Labor Relations Board had filed more than 80 complaints against Starbucks for refusing to negotiate in good faith with its workers in more than 280 of their stores that voted to unionize. “I look forward to hearing from Mr. Schultz as to when he intends to end his illegal anti-union activities and begin signing fair first contracts with the unions,” Bernie said.

I love him because he sounds like a vintage record (even his voice has the crackle of worn vinyl).

I love Bernie because he has endless patience for important things and no patience for unimportant conversation. In 2010, he delivered an eight-and-a-half-hour speech on the Senate floor to protest the extension of tax cuts instituted during George W. Bush’s presidency. I was in the Capitol at the time and dropped by his office to congratulate him on his marathon. He quickly thanked me, then waved me off to take a phone call.

Just before the California Democratic primary in 2020, he gave a stem-winder of a speech in Oakland. We had a late dinner at a small dive on Shattuck Avenue that was empty except for the two of us, until a supporter spied us through the window and came bounding in with a Bernie poster.

“Senator, would you sign my …?”

“Not now! We’re eating!” Bernie barked.

In all my years in and around politics, I’d never come across a candidate willing to do this.

I love Bernie because he’s a true populist, a word that has gotten a terrible rap since Trump arrived on the scene but should be redeemed. It means for the people and against the powerful. Trump pretends to be a populist, but he’s always wanted to be one of the powerful since he entered politics and been in their pockets.

I love Bernie because he has almost single-handedly changed the national conversation, turning proposals that had once been on the Democratic fringe into respectable and, in some cases, mainstream Democratic positions: creating jobs by rebuilding the nation’s infrastructure; providing free tuition at public universities; breaking up the big banks; guaranteeing workers paid medical and family leave.

I love Bernie because even in his 80s his indignation hasn’t faded, nor has his energy.

When he entered Congress in 1991 as an independent, he wasn’t particularly well liked. That may have had something to do with his telling the press that Congress “is not working. It is failing. Change is not going to take place until many hundreds of these people are thrown out of their offices” and charging that “Congress does not have the courage to stand up to the powerful interests. I have the freedom to speak my mind.” Congressman Barney Frank shot back: “Bernie alienates his natural allies. His holier-than-thou attitude — saying, in a very loud voice, he is smarter than everyone else and purer than everyone else — really undercuts his effectiveness.” Joe Moakley, another Massachusetts Democrat, then chairman of the powerful House Rules Committee, complained that Bernie “screams and hollers, but he is all alone.”

Bernie’s lack of popularity on Capitol Hill didn’t hold him back. He was reelected to the House seven times and was one of the founding members and the first chair of the Congressional Progressive Caucus, which has grown steadily from six members in 1991 to 97, as of this writing.

His ascent to the Senate in 2006 was astonishing — beating the Republican candidate, Richard Tarrant, one of the wealthiest men in Vermont, by 33 percentage points.

I backed Bernie in 2016 when he ran for the Democratic nomination for president against Hillary Clinton and backed him again in 2020. I took some crap for doing this from Clinton people, but I’m glad I did it. The system needed shaking up. It needed Bernie’s candidacy even if he wasn’t going to get the nomination.

In the 2016 Democratic primaries and then again in 2020, young people all over America wore buttons reading “Feel the Bern.” They were like the young admirers of Ruth Bader Ginsburg, another warrior who combined progressive conviction with elder crankiness.

I love Bernie because he has more guts than any politician I know. Hell, he has more guts than just about anyone I know.

As far as I’m concerned, AOC couldn’t find a better role model than Bernie, and Bernie couldn’t find a better mentee than AOC.

Democratic Socialism

Which brings me to the organization AOC is most identified with, the Democratic Socialists of America.

Soon after Bernie began running for the 2016 Democratic presidential nomination, his campaign manager warned me he was about make a speech to “introduce” the public to democratic socialism. I was impressed that he had the guts to do this but worried about his timing. “Does he have to do it now?” I asked. The campaign manager told me Bernie was committed to doing it and couldn’t be persuaded otherwise. It was pure Bernie.

Ever since Franklin D. Roosevelt pushed for Social Security, Republicans have used “socialism” to scare Americans away from doing anything big that we need done.

They still are. On Wednesday, Trump and a shameful parade of Republican members of Congress up for reelection excoriated Democrats for being “soft” on “communism” and “socialism.”

Last week, the House adopted a Republican-backed resolution (introduced by Colorado Republican Rep. Jeff Crank) that condemns socialism in all its forms and explicitly names the Democratic Socialists of America. (The vote passed 220–192. Eight so-called “moderate” Democrats broke ranks to vote with Republicans.)

But America is changing. A Cato Institute poll showed that 53 percent of Gen Z have a positive view of socialism, while 45 percent view capitalism positively.

I’ve taught a large number of students who call themselves socialists, but they do so mainly because they reject capitalism — its monopolies, its treatment of workers, its disregard of human rights, its raging inequalities.

Most don’t have a clear idea of what socialism means, other than more money spent on social services, safety nets, and public investment in schools, healthcare, and the poor — and higher taxes on the wealthy to pay for all of this.

Over the past year, the youth and student branch of the national Democratic Socialists of America has seen a massive surge in membership, growing by more than 50 percent and starting more than 50 new chapters. The organization claims it now has more than 3,000 members across 160 chapters, the most in its 50-year history. But compared to the American electorate — even voters under 30 — that’s still very tiny.

DSA’s growth reflects a growing national spotlight on the organization after a string of Democratic primary wins for candidates who align with the group, from New York to Colorado.

And it follows a tense year of campus organizing by pro-Palestinian students pushing their schools to divest from Israel amid its war with Hamas over Gaza, which had been the entry point for many college students into the DSA.

The focus of young people in the DSA has centered on divestment from Israel. But that’s not all. They’re also engaged in student worker labor organizing and pushing for “sanctuary campuses,” which involves both blocking ICE from college campuses and pushing schools to end corporate sponsorships that benefit ICE.

Just as JD Vance has wide support in Turning Point USA, the conservative group founded by the late Charlie Kirk, AOC has wide support in the growing ranks of the Young DSA.

AOC

So what do I tell the growing number of people — especially young people — who ask me about AOC’s presidential chances? I tell them the truth, as I see it.

She’s an extraordinarily gifted leader. She’s also an enormously powerful communicator (I don’t know any politician more skillful on social media). I admire her progressive views and values.

I doubt the nation is ready to elect a woman in 2028, especially after Kamala Harris lost to Trump in 2024 and Hillary Clinton lost to him in 2016. But it will be ready at some point, and I hope that point comes soon.

AOC is only 36 years old (37 in October). She has plenty of time. She also has nothing to lose and much to gain by trying for the nomination in 2028. It would give her even more of a national platform and hugely valuable exposure to and experience with voters in states that she doesn’t know well.

And if she doesn’t win the nomination for president, she can always run against Chuck Schumer to become senator from New York.

A new identity theft service launched on the dark web this week is selling digital scans of more than 153 million drivers licenses from people in the United States and Canada. Based on interviews with individuals whose licenses are available for purchase on this service, it appears to be siphoning images collected by a widely-used identity verification company based in Louisiana. KrebsOnSecurity also has learned that the New Orleans field office of the Federal Bureau of Investigation (FBI) today launched an official inquiry into the source of the images.

A record available at this identity theft service that includes the drivers license for U.S. Defense Secretary Pete Hegseth, who is one of several high-ranking U.S. government officials whose drivers licenses can be found for sale.

On Monday, Aug. 31, a source alerted KrebsOnSecurity to a service advertised by a new user on the Russian cybercrime forum Exploit, offering access to digital scans of identity documents on more than 170 million people in North America. The source brought it to my attention because the proprietor of this identity theft service offered my Virginia drivers license as a free sample in their initial sales thread on Exploit.

The service, dubbed Nexus, claims to have more than 153 million drivers licenses for people in the United States and Canada, as well as more than 10 million identification cards; more than three million travel documents and/or international IDs; and at least 579,000 medical cards.

A quick look around Nexus finds they are likely not exaggerating about that 153 million number: Running a blank search in Nexus (with no search parameters entered) returns approximately 11.5 million pages of results, with roughly 15 results displayed per page. It includes documents from people in both Canada and the United States, but the bulk of these records are on Americans: searching for just Canadian drivers licenses returns approximately 1.1 million results, with the largest concentration from Ontario (473,673 records).

Curiously, the identity records include not only drivers licenses but also marijuana dispensary cards. Some of the records list their “source” as “CDL,” presumably short for “commercial drivers license.” Other records carry the source notation of “CAC,” which may refer to Common Access Cards, government issued identity cards that grant physical access to government buildings and secure rooms.

The people behind Nexus claim the license images are coming from an active breach at “a major identity verification company” whose customers include multiple Fortune 500 companies.

The record totals listed by the Nexus identity theft service. The number of drivers license records increased by nearly 400,000 in the span of just 24 hours.

“We have been continuously exfiltrating new data for over a year into our private database,” the service enthused in its introductory post on Exploit. “Records are available to preview before purchase with pertinent information redacted. Customer photos are displayed if available.”

Indeed, over the past 24 hours, the number of drivers license records listed as available in Nexus has increased by nearly 400,000, suggesting that freshly stolen license data is being harvested and uploaded to this service on a semi-regular basis.

The record that features my drivers license includes six image files — three pairs of photos of the license’s front and back — a basic image scan — as well as infrared and ultraviolet versions of the same images. A date and timestamp is appended to each image file, and the timestamp on my license scan corresponds to a date in June 2025 when I took a flight to the midwest United States to attend a family funeral.

Some of the 153 million+ license scans — including mine — feature six image files with date and timestamps appended to the filenames. Not all records include photos, and some that do feature photos do not display the associated filenames.

Intent on discovering the source of this data, KrebsOnSecurity asked more than a dozen friends and family members for permission to search for their licenses in this service. Each person whose license could be found (nine of them) confirmed having traveled on or very close to the dates in the timestamps attached to their images. It is unclear what timezone these timestamps are in, but from reviewing car rental records shared by several people who helped with this research, it appears the timezone is set to Greenwich Mean Time (GMT).

At first, I thought the source of the data might have something to do with airports. However, that theory went out the window when it became apparent there were no passports in this data set. Also, only some of those who helped with this research said they showed their drivers license at the airport on the day of their travel. One person whose license was in Nexus hadn’t flown at all recently, but was renting a car from Hertz for several months around the date of their timestamp.

Two of those who agreed to help are federal employees who said they shared other forms of government identification when passing through airport security. However, those individuals each said they shared their state-issued drivers licenses later that day when renting vehicles at their respective destinations, and that both rented their cars from Hertz.

After finding a note in my calendar for the day of my June 2025 flight reminding me to bring my passport, I remembered that I also never actually shared my drivers license when I went through security at Reagan National Airport on that day because I did not yet have a Real ID, a security-enhanced drivers license that is now required by the Transportation Security Administration (TSA) for all domestic travel. Instead, I showed the TSA agent my government-issued U.S. passport.

Here’s where it gets interesting: I was able to find my mother’s drivers license in this service as well, and the timestamps for her images are just a few seconds apart from mine. That’s notable because we both handed our licenses to the Hertz rental car representative at the same time.

According to my mom, the only place she gave her drivers license to that day was the rental car company, and if memory serves that is also true for me. I don’t recall if the rental car representative inserted our licenses into any kind of machine, but I remember they held onto them for several minutes behind the counter while we were signing various forms. KrebsOnSecurity sought comment from Hertz and will update this story in the event they reply.

Zach Edwards is a well-known security and privacy researcher who recently launched a service called DecryptAds to help people better understand how online advertisers are tracking them. A scan of Edwards’s drivers license is available for purchase on this identity theft service, and Edwards said the timestamp on his record corresponds to the middle of a trip last month to Las Vegas for the annual DEFCON security conference.

Edwards told KrebsOnSecurity that although he did not rent a car in Vegas, he did hand over his license at the TSA checkpoint, at a marijuana dispensary in Vegas, and at his hotel (the Aria). But he said the only one of those three that for sure scanned his ID in some kind of device was the dispensary.

To enter Planet13’s weed dispensary in Las Vegas, one must pass through a red telephone booth. Image: Zach Edwards.

Edwards said the dispensary he visited that day was Planet13, a multi-state chain with stores in California, Florida, Illinois and Nevada. In 2022, the New Orleans-based identity provider idscan.net published a press release announcing an exclusive identity verification agreement with Planet13’s dispensaries nationally. IDScan says it processes ID verification for more than 1,000 marijuana dispensaries in 19 U.S. states.

The “trust” page of idscan.net states that the company provides identity verification services for numerous big brands, including Hertz, Target, Fedex, Motorola Solutions, the financial services giant Jack Henry, and Caesars Entertainment. And as idscan.net’s own documentation states, the technology scans IDs with both infrared and ultraviolet light. Idscan.net says the company’s systems and technology perform more than 21 million verifications monthly, at more than 20,000 locations around the world.

Image: idscan.net.

Contacted by KrebsOnSecurity, idscan.net said it was investigating the matter, but the company has not yet shared an official statement or a substantive reply to specific questions sent via email.

“At this point I’m not able to share any additional information, but the updates you have provided have been welcome, and helpful to our team’s investigation,” wrote Jillian Kossman, a marketing and operations leader at idscan.net.

During the course of my research for this story, word apparently got around to the FBI that I was poking at the apparent source of this new identity theft service’s data. Probably they were tipped off when I shared with a trusted source that Nexus also is selling the drivers license information for the assistant director of the FBI (I did not find FBI Director Kash Patel’s license in Nexus).

Earlier this afternoon, I was added to a conference call with a half-dozen FBI agents, including senior leaders from the agency’s cyber division. During that call, the FBI shared that earlier today their New Orleans field office opened an official investigation into an apparent breach involving idscan.net.

Edwards said that as more in-person and online experiences require sharing drivers licenses, vendors who collect this sensitive data need to be held to a higher standard.

“This episode should further strengthen the resolve for people who are fighting back against online ID schemes which are requiring countless providers to ask for drivers licenses in order to access services under the guise of protecting kids,” Edwards told KrebsOnSecurity. “These systems are putting sensitive data into more and more 3rd party vendors, and we don’t have nearly the oversight to ensure they are safe.”

Larry Baldwin is principal intelligence researcher at the cybersecurity firm Cybera. Baldwin said a front and back scan of his drivers license available at Nexus contains timestamps that correspond to the date of a car rental from Hertz on a recent vacation.

Baldwin said the Nexus identity theft service presents multiple serious security and privacy threats, noting that state-issued drivers licenses are commonly used as proof of one’s identity when opening new lines of credit. Baldwin said the service could also dangerously expose many people who do not wish to be found but who cannot meaningfully change their appearance (or at least not enough to fool today’s AI-based image matching tools).

This category of people, he said, includes those fleeing domestic violence, and even people who have been assigned a whole new life and identity as part of the federal government’s witness protection program, which is generally reserved for criminal defendants in racketeering and conspiracy investigations who agree to cooperate with federal authorities.

“Just when it seems like we’re making some headway in improving authentication controls through drivers license verification systems, this happens and the very thing those improvements are dependent on are compromised,” Baldwin said.

This is a potentially fast-moving story. Any changes or updates will be noted here along with a timestamp.

The actual epistemic crisis (permalink)

AI is alarming for many reasons: it's a dangerous financial bubble, an environmental catastrophe, and a tool for eroding wages and labor power. But in addition to all that, AI is an epistemic disaster.

We've had photoshopped images, voice impersonators and visual effects for years, of course, but with deepfakes, we've democratized access to reality-bending images, sounds and videos that appear real but are not. It's harder than ever to know what's true. Politicians and celebrities and activists show up in our feeds, declaring their fealty to this cause or product, or their fury at some turn in the world's events. Battlefields mound high with bodies and influencers marvel at impossible, sumptuous meals. It all seems plausible, and some of it is real, but not all of it, and because we know some of it is fake, we can't be sure if any of it isn't.

It's a very putinesque way of living. Vladislav Surkov was Vladimir Putin's media strategist, and he had a deadly effective tactic: he announced that he was covertly funding some of the groups that publicly opposed Putin, but did not disclose which of those opposition groups were fake. That meant that any of the groups could be fake, which meant that any discussion of the opposition was liable to devolve into an argument about its authenticity. Anything could be a lie, so nothing was necessarily true. Putin's method isn't to get you to believe a lie – it's to keep you from believing that anything is true.

That's life under AI – a world of uncertainty, an epistemological void full of plausible phantasms, some of which are actually real. A world where it's impossible to know what's true, and where anything might be fake.

But here's the thing: AI's assault on our ability to know isn't a new battle – rather, it's the latest barrage in a war that's been waged for years, as corporations grew larger and more powerful, capturing their regulators, who let them lie to us and abuse us with impunity.

This complicated, technical world – the world that produced AI – is full of complicated, technical questions, and none of us can answer these questions for ourselves. You're not stupid, but even a generational genius could not acquire the expertise to answer the long list of life-or-death questions we face every day.

Are the food hygiene standards followed by your grocer or lunchtime spot adequate, or will your dinner make you shit yourself to death? Are the building codes that specify the alloys in the steel joists that hold up the roof over your head sufficient, or are you about to be crushed to death? Is the software in your anti-lock brakes any good, or will you die in a fireball on the way to work?

From food additives to pedagogy, psychotherapeutic techniques to retirement savings, it would take a hundred lifetimes for you to acquire the 200 PhDs needed to answer these questions for yourself.

Thankfully, we don't have to answer those questions for ourselves. Instead, we defer to expert agencies: governmental regulators that assess truth claims by soliciting input from all comers, publicly deliberating about the evidence they've gathered, and then making a rule in public. These regulators are meant to be experts, nonpartisan and neutral, operating with the highest degree of probity, recusing themselves in the event of even a whiff of conflict.

It has to be that way. You may not be able to assess claims about the safety of vaccines – or opioids – but you can see for yourself whether the FDA is full of ex-pharma execs. You can see for yourself whether pharma company lobbyists all used to work for the FDA. You don't need to be a virologist or a cell biologist to tell whether the system that's supposed to sort truth from lies is fit for purpose.

It is not fit for purpose. When arguments broke out over covid vaccines, many vaccine advocates characterized their opponents as foolish people engaged in foolish conspiratorialism. They argued that the corporations that produced the vaccines and the regulators who oversee them were intrinsically trustworthy, and on that basis, we should all get vaccinated.

Now, I happen to be a big believer in vaccination. I've had so many covid jabs that I glow in the dark and get five bars of 5G in a coal-mine. But I didn't get vaccinated because I trust pharma companies or their regulators. A string of scandals – most notably the Sacklers' Oxycontin murder-spree – has proven that pharma will kill you for a nickel and that the FDA will let them get away with it:

https://pluralistic.net/2024/03/25/black-boxes/#when-you-know-you-know

From tobacco safety to food safety to the climate emergency, it's obvious that the system of expert agencies that we rely on was terminally compromised by corporate power and regulatory capture:

https://pluralistic.net/2022/06/05/regulatory-capture/

This is the epistemological void we were already adrift in before AI came along: a world of unresolvable, urgent, terrifyingly high-stakes questions.

When you get a call from "your bank" and accede to the demand that you hand over all kinds of personal information before they will disclose the call's purpose, you're not being naive or foolish – you're doing the thing that our banks have conditioned us to do for years by engaging in exactly this behavior (my bank did this to me this week!). Why are banks allowed to get away with engaging in this kind of outrageous conduct? Because – as we've repeatedly discovered through crisis after crisis – banks are too big to fail, too big to jail, and too big to care.

Why is it so believable that a loved one might call you in a panic because they've been arrested or injured and need an immediate cash payment before they can get bail or doctor's treatment? Because our criminal justice system and our health care system are already plagued by this kind of inhumane, high-handed, extortionate behavior.

Why do you fall for a deepfake of celeb shilling for supplements or a shitcoin? Maybe it's because celebs actually shill for supplements and shitcoins, and face no consequences for helping rope us all into scams:

https://gizmodo.com/matt-damon-crypto-com-crypto-bitcoin-1850282413

Not just celebs – also our newspapers:

https://www.nytimes.com/interactive/2022/03/18/technology/cryptocurrency-crypto-guide.html

We laugh when other people fall for newspaper articles making absurd claims – but after living through a time in which our most respected journalistic outlets credulously helped a dishonest government lie the world into a war that's still smoldering more than a generation later, who can be sure when to trust the papers?

https://www.nytimes.com/2004/05/26/world/from-the-editors-the-times-and-iraq.html

One of the reasons it is so hard to agree on covid's death-toll is that so many of the people who died of covid were already compromised by chronic illnesses or "pre-existing conditions" from cancer to heart disease. Those people did die of covid – and they died of cancer or heart disease or some other comorbidity. Covid was an opportunistic infection that inflicted disproportionate harms on people who were already suffering.

The epistemic void created by AI is another opportunistic infection. Our ability to know things has been in decline for generations, as monopolies shredded our truth-assessment systems, rendering us all incapable of knowing the truth in a world where believing lies could bankrupt you or kill you dead.

If you could trust your government's expert agencies and if they had reliable systems for making their findings known; if your bank was banned from engaging in conduct indistinguishable from phishing; if the health-care and criminal justice systems never forced the people they ensnared to call their relatives and beg for money, then deepfakes would have a much harder time penetrating our cognitive immune systems.

It's not so much that AI is a powerful way of lying – rather, we have been made progressively more vulnerable to lies for decades, leaving us at an epistemic death's door, and AI has arrived to deliver the coup de grace.

Taxi and ambulance drivers are less likely than workers in almost any other job to die of Alzheimer’s disease. That was the surprising result of a 2024 study examining the death certificates of nearly 9 million people in the U.S.

These findings stopped me in my tracks because those two jobs rely on the same thing as my own work: maps.

I have spent more than two decades staring at maps. Not paper maps on a wall, but digital ones with multiple layers: flood boundaries draped over census blocks, car crash hot spots plotted against road geometry, and satellite readings of rainfall stitched across river basins. Much of my work as a civil and environmental engineer is done through GIS – that is, geographic information systems. Engineers like me hold several spatial relationships in their minds at once, reasoning about where things sit relative to one another across scales ranging from a city block to a whole watershed.

I always assumed that spatial reasoning across map layers was purely professional. But that study on taxi and ambulance drivers made me wonder whether all that mental work might be doing something good to the brain.

Taxi driver brains

Of the 9 million death certificates from January 2020 to December 2022 that researchers examined, taxi and ambulance drivers had the lowest risk of dying from Alzheimer’s disease out of 443 occupations. After adjusting for age, sex, race, ethnicity and education, roughly 1 in 100 taxi and ambulance drivers died of Alzheimer’s, compared with 1 in 60 people overall.

This pattern did not extend to other driving jobs. The researchers concluded that the key to reducing the risk of Alzheimer’s was not driving itself but continuous real-time navigation: the constant work of locating yourself in space, tracking a destination and updating a mental map as conditions change. Drivers whose jobs relied on fixed or predetermined routes, like bus drivers and aircraft pilots, didn’t seem to experience a similar advantage.

Researchers believe the association between navigation-heavy work and lower Alzheimer’s risk centers on the hippocampus, a part of the brain that governs memory and spatial navigation. It’s one of the first brain regions that Alzheimer’s damages: Problems with spatial navigation and orientation are among the earliest signs of the disease, sometimes surfacing before obvious memory loss.

In one landmark 2000 study, neuroscientists compared the brains of licensed London taxi drivers with those of people who did not drive cabs. Their findings provided the first evidence via structural imaging that regions of the adult brain can measurably change under sustained navigational demand. To earn a license, London cabbies must memorize more than 25,000 streets within a 6-mile radius of Charing Cross, a challenge known as “The Knowledge” that takes three to four years.

The researchers found that London taxi drivers had measurably more gray matter in the posterior hippocampus, a brain area tied to storing large-scale spatial maps. That volume tracked with experience: The longer someone had driven, the larger that part of the brain. The change was built through practice, not inherited. While people who are good at navigation might gravitate to this kind of job, the job itself does have an impact on the brain.

Together, these two studies make a coherent case: Work that intensively exercises the hippocampus may reshape it, and that reshaping may protect against one of the most feared diseases of aging.

Where map specialists fit in

Cartographers, urban planners and geospatial analysts spend their working days in sustained spatial reasoning. A geographic information system specialist might use a computer to overlap population data on flood exposure maps to find who is at risk, or read satellite imagery to map land cover after a wildfire. Researchers juggle several layers of data, coordinate systems and scales at once.

Does spatial reasoning through a screen engage the hippocampus the way moving through a real city does?

While a taxi driver navigates from inside the scene at street level, GIS researchers picture space from above as a map – what cognitive scientists call allocentric reasoning. But these two perspectives overlap in the brain: The hippocampus also builds maps from outside viewpoints, not just from a navigator’s own position.

Research on cognitive maps points toward the same conclusion as the study on taxi drivers. In 2023, researchers ran a machine learning model on more than 22,500 people in a national dataset and were able to predict which ZIP codes had higher rates of Alzheimer’s with 84% accuracy based on how complex the environment was. Those living in spatially complex surroundings – the kind that force active map building, such as dense street networks with numerous intersections, diverse points of interest and landmarks, and multiple path options – were less likely to develop Alzheimer’s.

A follow-up study tied geospatial complexity in one’s environment to greater volume in the brain’s spatial navigation regions. The researchers hypothesized that routinely building cognitive maps exercises the very circuitry that Alzheimer’s attacks first. Repeatedly engaging the cognitive systems involved in spatial navigation could help delay symptoms of disease.

However, these two studies focus on where people live, not the work people do. Whether spatial reasoning through a screen exercises the same circuitry as real-life city navigation remains untested.

Protecting your brain

The implications of whether sustained spatial reasoning protects the brain reach beyond mapmakers and cab drivers. Studies have repeatedly found a link between mentally complex occupations and delayed cognitive decline and lower dementia risk, even after accounting for education.

Research on cognitive reserve – the brain’s capacity to continue functioning despite disease – can help explain why two people with a similar disease burden can show markedly different levels of cognitive impairment. If demanding spatial thinking protects the brain, then how societies design schooling, professional training and retirement all become questions of brain health.

Spatial reasoning can be trained, and training opportunities are already widespread. GIS and remote sensing instruction are available through geography, engineering, public health and environmental science programs worldwide.

If sustained engagement with spatial reasoning can help the brain strengthen the circuitry that Alzheimer’s attacks first, its value reaches well beyond the technical skills it builds.

The nationwide cyclospora outbreak is very likely a result of sewage contamination in the food supply, according to scientific researchers and public health officials.

The parasite’s spread can become a self-perpetuating cycle. Cyclospora is found only in humans, where it replicates in the intestinal tract, causing severe diarrhea. The organism reproduces by releasing oocysts, which are excreted in those human feces. In the U.S., feces usually end up in sewage systems.

In many states, sewage water is treated – though not always in ways that remove or kill the oocysts – and then released into waterways and can be used to irrigate crops. The oocysts mature in the environment with warm temperatures in about a week. Then a human comes along and eats the irrigated food or drinks the water and gets sick, releasing more oocysts into sewage systems.

I am a public health water microbiologist who collects sewage water and tests it for evidence of harmful pathogens, such as cyclospora. The first time I studied cyclospora was in the first outbreak ever documented in the U.S., a small, 45-case outbreak in Florida in 1995.

The cause was initially suspected to be strawberries grown in California, but later it was determined it was more likely due to imported contaminated raspberries from Guatemala. That country’s raspberries were also associated with much larger outbreaks in 1996 and 1997. At the time, little was known about this single-celled protozoan pathogen.

More than 30 years later, the largest outbreak ever recorded in the U.S. has sickened more than 22,000 people, and contributed to the deaths of two in Michigan, where I live and work. Using treated sewage to irrigate crops is common in many places, especially where groundwater and surface water are in short supply.

What’s in wastewater

There are two reasons researchers like me collect sewage and monitor what’s in it.

The first is to evaluate levels of disease in a community. Measuring viruses such as SARS-CoV-2 in untreated sewage helped paint a picture of the spread of COVID-19 and the emergence of variants as the pandemic continued.

The second reason is to determine whether and how sewage treatment removes, inactivates or kills pathogens.

It is not easy to measure cyclospora oocysts in sewage, contaminated water or food. Even modern laboratory methods have trouble reliably detecting low levels of oocysts, which can still cause disease.

Cyclospora oocysts have been found in sewage around the world. A range of studies across the world shows that they can be detected in up to 25% of sewage samples – but not all studies report how high or low the concentrations of the oocysts were. So it can be hard to say exactly how widespread it is.

A person who is infected with cyclospora excretes somewhere between 100 and 10,000 oocysts per gram of feces for as long as 60 days. Based on what is known about other fecal pathogen excretions from patients, related to the concentrations of those pathogens in sewage, I estimate that there could be anywhere from 1 to 100 oocysts per liter in sewage.

Our laboratory at Michigan State University is developing a method to more accurately detect this parasite even at lower levels in sewage. This type of wastewater surveillance may help determine when an outbreak is beginning to subside and where larger numbers of people are still affected. In addition, this information could allow sewage treatment plant managers to regularly monitor their discharges.

What happens during sewage treatment?

There isn’t clear data on how well standard sewage treatment processes reduce the numbers of cyclospora oocysts. But there is information on two other similar protozoa that also cause significant diarrhea in humans: Cryptosporidium produces an oocyst about half the size of cyclospora, and giardia produces a cyst that is similar in size to cyclospora.

From 2001 to 2003, my laboratory studied the occurrence of those protozoa at six sewage treatment plants – one each in Arizona and California and four in Florida. All had been approved by their respective state regulators for nonpotable reuse, including irrigation of landscapes and, in some cases, crops.

In that study, we found these protozoa in all the untreated sewage we tested, indicating there is some portion of the population that is infected and excreting their cysts or oocysts.

The five treatment plants whose processes included disinfection with chlorine were able to get rid of a high percentage – but not all – of the protozoa in their discharged wastewater. Some cysts and oocysts remained intact, with the potential to cause disease, even in water that had gone through the entire treatment process, as it is known that wastewater chlorination does not kill these protozoa.

From that data, it seems reasonable to assume that at least some small proportion of cyclospora oocysts also survive sewage treatment processes and are released back into the environment, where they can survive for months.

What about reuse?

Across the U.S., 200 billion gallons of treated sewage wastewater are used for irrigation of agricultural lands each year.

Some of that wastewater undergoes additional filtration and disinfection for reuse before being spread directly on landscapes or crops. The volumes, however, are not readily known. And other treated sewage, which undergoes only standard secondary treatment, is discharged into rivers, streams and reservoirs that could provide irrigation water.

But few states regulate efforts to remove or monitor protozoa such as cyclospora in treated sewage. Filtration can remove protozoa but must be designed and operated correctly. Chlorination is not effective, but ultraviolet light does inactivate cryptosporidium and eimeria, a chicken protozoan highly related to and used as a surrogate in studies testing methods of killing cyclospora by the food safety industry.

What is needed for better risk assessment and management?

As floods and droughts occur routinely across the U.S. and around the world, sewage may overflow into bodies of water or be used directly on crops. That increases the risk that diseases, including protozoa such as cyclospora, which are transmitted through ingestion of fecal matter, may spread through food and water supplies.

And because cyclospora oocysts mature in outdoor heat, it is possible that increasing temperatures, such as heat domes, could speed up their maturation, exposing more people to the infectious form of the parasite.

Modern technology and techniques are capable of monitoring water quality, detecting harmful pathogens and eliminating them. Expanding monitoring of wastewater for protozoan diseases and other dangers can help prevent outbreaks and slow the spread of disease from sewage-contaminated water in the future.
