Talk about homework: a large class of undergraduates at an unnamed university in Utah became the unfortunate subject of a severe public health response after an extraordinary bungle in a science lab.

In September of last year, the group of lab students were tasked with identifying a bacterium known as P. shigelloides, a relatively harmless pathogen known to cause diarrhea when ingested. But as lab results came in, students were alarmed to find the specimens handed out in class were actually the bacteria Neisseria meningitidis, a potentially deadly pathogen that causes meningitis.

Unlike P. shigelloides, the bacterium N. meningitidis calls for high-security practices, like double gloves, disposable clothes, and fit-tested N95 masks, as the bare minimum. (In one unfortunate case from 2012, a 25-year old microbiologist whose lab was ill equipped to handle N. meningitidis died mere hours after exposure to the aerosolized microbe.)

According to People, Utah public health authorities soon raided the Utah stockroom, finding samples labeled “N. meningitidis.” That discovery prompted a recommendation that all 33 of the exposed students begin a cautionary antibiotic regimen, especially given that the lab participants were only wearing gloves and lab coats at the time of exposure.

On top of the antibiotics dose, at least two people sought medical attention due to possible exposure symptoms, which included a painful and invasive spinal tap.

It was only after the frenzy that further professional lab tests identified the offending pathogen as Neisseria sicca, a bacterium “commonly found in the upper respiratory tract” that is “nonpathogenic in immunocompetent persons,” according to a recently-filed Center for Disease Control study of the Utah lab incident.

Student misidentification notwithstanding, the event underscores the importance of accurately labeling microbial cultures — lest aspiring biologists become victims of their own studies.

Even notorious anti-vaxxer and US health secretary Robert F Kennedy Jr had to urge families to vaccinate their children against measles last week.

Despite being an entirely preventable disease thanks to a highly effective vaccine that has been widely available since the 1960s, cases of measles have skyrocketed in recent years, facilitated by a White House that’s declared war on scientific research, made a mess of childhood vaccine mandates, and furthered dangerous misinformation.

As of last week, the US had recorded 2,465 confirmed infections so far this year, already more than the 2,289 total cases in 2025. The last two years saw more total infections than the rest of the 21st century combined, as The Guardian reports, with 2026’s tally beating a 35-year record.

Now, in the midst of all that crisis crisis, a character has stumbled into the narrative who perfectly illustrates how it’s gotten so bad. As the LA Times reports, a measles-infected individual spent a whopping 11 hours at the Universal Studios Hollywood theme park last month, potentially exposing countless other visitors.

The Los Angeles County Public Health Department was forced to issue a stark warning: anybody who visited the amusement park on July 26 during teh hours between 10am and 9pm may have been exposed and should monitor for symptoms including fever, cough, or rash — and stay vigilant until August 16.

The virus is contagious up to four days before the characteristic rash appears on the skin, and up to four days after that.

Measles can easily spread through the air through just via talking or breathing, and can persist on surfaces for hours at a time.

The vaccine against it, available as part of the measles, mumps, and rubella combination (MMR) shot, is extremely worthwhile. Two doses are 97 percent effective in preventing a measles infection.

The department also urged “everyone to confirm their immunity and get the vaccine if needed, especially before traveling and attending crowded events.”

California has been hit particularly hard, recording at least three localized measles outbreaks this year so far. However, according to the state’s health department, all three outbreaks have ended.

According to the Centers for Disease Control and Prevention, there have been 38 new outbreaks in 2026 across the country so far this year, with several thousand cases spanning 47 states.

The danger to one’s health is substantial — especially to the unvaccinated. According to the CDC, roughly one in five unvaccinated people in the US who get measles are hospitalized. One out of 20 children with measles develop pneumonia. and one to three of every 1,000 children who become infected die from respiratory and neurologic complications.

In case you weren’t already feeling paranoid about how AI is shaping our future, scientists for the first time have used an AI model to create new and viable viruses that have never been seen in nature.

Before you panic, the work, detailed in a study published in the journal Science, involved creating viruses that only target bacteria and are harmless to humans. Bacteriophages, as they’re called, are an important medical intervention for targeting drug-resistant pathogens.

“This is an important milestone,” Patrick Cai, a synthetic biologist at the University of Manchester who was not involved in the study, told The New York Times.

Still, it’s an alarming testament to AI’s power and trajectory. The researchers at Stanford University and the Arc Institute trained an AI model to recognize patterns of genetic structure in nature to create new DNA molecules. These molecules were inserted into bacteria that, over time, turned into wholly new viruses, at the expense of killing their hosts.

In their research, which first gained attention last year but has now been peer-reviewed, the scientists used an AI model called Evo. Unlike a general purpose large language model, Evo is trained on billions of lines of genetic sequences, and for this work in particular, millions of bacteriophage genomes. But it still functions like an LLM, predicting what DNA building blocks — nucleotides — should follow each other like a chatbot predicts what words to spit out to finish a sentence.

The researchers chose to focus on a E. coli-killing virus called Phi X-174, a variant that’s so well studied that it serves as the equivalent of a lab rat in virology. Viruses in general are simple compared to complex cellular life, making them an ideal platform to test AI’s capabilities.

They used Evo to create new viruses based on Phi X-174, and it generated 700,000 candidates. They then narrowed it down to just 300 that they would recreate in the lab. Of those 300, 16 proved to be viable, infecting and killing their bacterial hosts.

There’s clear medical merit to using AI to create bacteria-slaying viruses, but there’s already fears that the technology could be abused to crank out pathogens that are deadly to humans.

“Although this is promising for life sciences applications, it also raises urgent biosafety and biosecurity questions. The ability to compose viral genomes using generative AI now exists; the governance to safely steer it does not,” warned Tom Inglesby and Moritz Hanke at the Center for Health Security at Johns Hopkins University in Baltimore in a perspective article.

Tom Ellis, a professor of synthetic genome engineering at Imperial College London who was not involved in the research, acknowledged this threat, but told The Guardian that it would be much harder to create more complex genomes and that controlling access to genetic data could stymy the threat.

And if someone were to deliberately engineer deadly viruses, he added, doing it by hand would probably be more practical.

“But honestly, the threat from full AI design and writing of a genome of a virus or bacteria is very overblown when we consider that just taking existing pathogens and making gain-of-function changes to their genomes is so much easier and much more likely to be a real pathogenic threat,” he said.

Prediction markets like Kalshi and Polymarket have long garnered a reputation for allowing users to make all kinds of ethically dubious bets, from the outcomes of deadly conflicts to mass famine. 

As the New York Times reports, Kalshi will now even allow users to bet on whether clinical trials for potentially lifesaving drugs will succeed.

To critics, the move will effectively allow betting on the lives of patients trying a final intervention in the face of a lethal diagnosis. There’s even risk that those enrolled in these trials could choose to drop out if the market were to bet against a positive outcome.

“Turning loose a betting market in an ongoing randomized clinical trial really is a breach of scientific conduct,” Robert Califf, who served as FDA commissioner in the Biden administration, told the NYT.

Kalshi first announced its “biotech prediction markets pilot program” last month, the same day president Donald Trump’s teleprompter guy was busted for winning more than $100,000 on Kalshi by betting on what he would say.

The company argued in the announcement that a “publicly listed contract on a trial or regulatory outcome produces a continuously updated, public probability that reflects the weight of the evidence rather than the preferred messaging of the trial sponsor.”

In a statement to the NYT, spokesperson Jack Such argued that these bets wouldn’t undermine research integrity, but instead cut through the hype surrounding biotech companies and the drugs they’re working on. 

Kalshi says it will prohibit betting by patients enrolled in a trial, as well as by employees of the company conducting it or its competitors, per the NYT. It will also ban betting on trials that “exclusively enroll minors,” at least at first.

But those enrolled in drug trials were left appalled by the news.

“We’re literally trying to stay alive,” metastatic pancreatic cancer patient Walter Ingaharro Jr told the NYT. “It’s not a game. The introduction of gambling into the process really creates an ethical mess.”

In an opinion piece for The Guardian, Boston University humanities professor Joshua Pederson talked about how his 12-year-old son has a “very aggressive tumor growing inches below his heart.”

“If Kalshi has its way, you could soon be able to bet on health treatments that could be essential to his survival,” Pederson argued.

While choosing a trial for his son’s cancer was a “terrifying experiment for which we feel ill-prepared,” turning to a prediction market instead of “our extremely qualified team of oncologists” feels “preposterous,” Pederson argued.

In short, it’s yet another example of prediction markets crossing a moral boundary by gamifying things with real-world consequences.

“The possibility that somebody out there might be wagering against my son, hoping that the treatment fails so they can make money, is enraging,” Pederson wrote. “How is this not just another type of ‘death market’ — like markets for war or assassination — that even Kalshi says it won’t abide?”

The headline of this story was updated to specify that the program would bet on the outcomes of clinical trials, and the piece was updated to more specifically refer to controversies around prediction markets like Kalshi, writ large, and to add details about Kalshi’s response.

For a president who upholds “Make America Healthy Again” as a load-bearing narrative pillar, Donald Trump has gone to remarkable lengths to make the US a breeding ground for a widening range of viruses, bacterium, and parasites — and no, we’re not talking about his cabinet.

Early into his second tenure as commander-in-chief, Trump and his cronies set to rapidly dismantling offices doing critical work on public health. His appointments were a one-two punch on longstanding institutions safeguarding the US from the ravages of disease: Elon Musk’s DOGE cut the government’s capacity to identify and track public health problems, while Robert F Kennedy Jr’s Department of Health and Human Services limited what the government was willing to do about them.

Case in point: the Centre for Disease Control has lost nearly a quarter of its workforce since January 2025, while those who remain have watched in horror as the CDC’s acting director cut the number of universally recommended childhood vaccines from 17 down to 11.

Examples of those kinds of policy faceplants abound, and the cumulative consequences will surely be felt for decades to come. And nowhere are the consequences of the Trump administration’s war on public health more obvious than in the diseases we’d previously had under control, but which are now surging back after a year and a half of MAHA.

There’s the cyclospora outbreak, of course, spreading from tainted lettuce to over 18,000 victims across 45 states. And those are just the ones we know about — the true extent may be far worse, as reporting delays create a major lag in fresh data. And while cyclospora flare ups come and go, it’s hard to overlook the fact that Trump officials made reporting of the parasite optional for the CDC in 2025, right before the largest known outbreak in modern history.

Separately, a nation-wide salmonella outbreak prompted officials to recall millions of cartons of eggs as at least 100 cases were reported throughout the country. Though salmonella reporting is still mandatory for the CDC, the Food and Drug Administration under Trump has delayed the implementation of a food traceability rule, designed to speed up the tracking of food borne illnesses back to their source.

The reason for the delay? Budget cuts.

Beyond foodborne illnesses, there are even more nasty bugs spreading around the country under Trump’s watch.

The formerly-eradicated measles is back, with over 2,300 American infected in 2026 alone, the highest number since 1992, Vox reported. Flesh-eating screwworms are ravaging livestock, as staffing cuts and mandatory budget reviews at the US Department of Agriculture slowed government containment efforts. Even the nightmarish botulism toxin has made it into the headlines, entering the food supply via contaminated infant formula after the Trump administration disbanded the National Advisory Committee on Microbiological Criteria for Foods — coincidentally right as the group was about to release a report on infant formula.

We could go on. While some will surely shoot back that these diseases are always hanging over us regardless of who sits in the Oval Office, that’s exactly the point.

Public health isn’t a game of checkers, where enemy pieces leave the board once they’re conquered. It’s more like a game of whack-a-mole, demanding quick reflexes, a mallet, and someone to wield them with unending focus. Under Trump, the mallet has been sold off to the highest bidder, while the player has wandered off, convinced the moles are a hoax.
