Welcome back to the Abstract! These are the studies this week that got hosed with star spray, mounted a failed invasion, declined to comment, and achieved previously unknown levels of adorability.
First, a study about how the solar system wasn’t destroyed 4.5 billion years ago (phew!). Then: a human touch on an ancient boat, the duality of posters and lurkers, and an important update on toadlets.

Earth was cosmically conceived in part by a massive shockwave from a nearby supernova, which seeded our home world and neighboring rocky planets with telltale radioactive signatures, according to a new study.
The solar system’s rocky planets contain short-lived radionuclides (SLRs), which are ancient elements that were likely barfed out from exploding stars. For this reason, scientists have long suspected that stars must’ve detonated next to the gassy disk that gave rise to the solar system. The heat generated from these radioactive elements helped the building blocks of the rocky planets—Mercury, Venus, Earth, and Mars—melt together so they could become whole worlds, which means we owe our existence to these ancient supernovas.
Now, a team has developed a new model to explain how the primordial pyrotechnics didn’t just blow up the nascent solar system. The results suggest that rocky Earth-like worlds may be common in the universe, with potential implications for the search for extraterrestrial life.
“A key question in astronomy is how ubiquitous Earth-like rocky planets are,” said researchers led by Ryo Sawada of the University of Tokyo. “The formation of terrestrial planets in our Solar System was strongly influenced by the radioactive decay heat of SLRs, particularly aluminum-26, likely delivered from nearby supernovae.”
“However, the supernova injection scenario faces an unresolved problem in that existing supernova models could not reproduce both the relative and absolute abundances of SLRs without disrupting the protosolar disk,” an event that “would likely prevent the Solar System formation altogether,” the team added.
In other words, it’s hard to explain how the solar system got its high abundance of SLRs without killing it in the cradle. Sawada and his colleagues propose a solution that involves at least one star exploding about three light years of the disk, sparking a shockwave that created a cosmic-ray “bath.”
In this “immersion mechanism,” energetic cosmic rays trapped in the bath triggered SLR-producing reactions directly within the disk. This contrasts with the hypothesis that the SLRs were largely injected and then mixed up in the disk through some unknown process. This new solution can account both for the high abundance of certain SLRs, like aluminum-26, and the fact that the solar system was not destroyed, as evidenced by its apparent continued existence.
“Our results suggest that Earth-like, water-poor rocky planets may be more prevalent in the
Galaxy than previously thought,” the team said, noting that many disks are rocked by similar supernova-shockwaves. “This challenges previous interpretations that classified the Solar System as an outlier with a particularly high [aluminum-26] abundance.”
In addition to offering a new hypothesis for an old astronomical problem, the study gets bonus points for its extremely poetic title: “Cosmic-ray bath in a past supernova gives birth to Earth-like planets.” If you say this enchanted phrase three times, somewhere an Earth-like world will be born.
In other news…
Stars aren’t the only things leaving their dirty fingerprints in unexpected places this week. Archeologists working on the mysterious Hjortspring boat, a 2,400-year-old Scandinavian vessel, discovered a tantalizing partial human fingerprint in its caulking, providing “a direct link to the ancient seafarers who used this boat,” according to the study.
The ridges of the fingerprint “fall within average distributions for both adult male and females as well as for juvenile adults, making it difficult to say much about the individual who produced the print,” said researchers led by Mikael Fauvelle of Lund University. “The most likely interpretation, however, is that it was made during repairs by one of the crew members on the boat itself, providing a direct link to the seafarers of the ancient vessel.”
Regardless of this person’s identity, their voyage didn’t end well. Researchers think the crew of the Hjortspring boat probably sailed from the eastern Baltic Sea to attack the Danish island of Als, where they were defeated. “The victors [deposited] the weapons of their vanquished foes together with one of their boats into the bog,” where they remained for millennia until they were rediscovered in the 1880s, the team said.
It’s a timeless reminder for would-be invaders: Don’t get caulky.
At last, scientists have investigated the most elusive online demographic: the humble lurker. A team recruited 520 Redditors in the U.S. to participate in small subreddits focused on a variety of political topics during the summer of 2024. The aim was to probe why some people became prolific “power-users” that post with voluminous confidence, while others remained wallflowers.
“Online political discussions are often dominated by a small group of active users, while most remain silent,” said researchers led by Lisa Oswalt of the Max Planck Institute for Human Development. “This visibility gap can distort perceptions of public opinion and fuel polarization.”
The team found that “lurking (posting nothing) was most common among users who perceived discussions as toxic, disrespectful, or unconstructive.” Lurkers were offered small payments to post in the experiment, which succeeded in motivating some to contribute to discussions. As a result, the study concluded that “future interventions may be able to make online political discussions more representative by offering more positive social rewards for lurkers to post.”
At last, an opportunity to unionize the lurkers of the world. Solidarity (in silence) forever.
We will close, as we have before, with an impossibly cute toadlet. Scientists have discovered this new species of “pumpkin toadlet” in the “cloud forests” of Brazil, a sentence so twee that it’s practically its own fairy tale. The tiny toad Brachycephalus lulai, pictured below on a pencil tip, belongs to a family of “flea toads” that are among the smallest vertebrates on Earth.
“Our team sought to better document the individual variation of all Brachycephalus species in southern Brazil, looking for them in the field over the past seven years,” said researchers led by Marcos R. Bornschein of São Paulo State University. “As a result of this work, we discovered and herein described a population collected on the eastern slope of Serra do Quiriri as a new species.”
The team also reported that the toads are actively colonizing newly formed cloud forests, which are high-altitude woods shrouded in mist. The researchers propose making these unique habitats into refuges for the adorable anurans.
Thanks for reading! See you next week.

This article is a partnership between Reveal and 404 Media.
Jesus Gutiérrez, 23, was walking home one morning from a Chicago gym when he noticed a gray Cadillac SUV with no license plates. He kept walking, shrugging it off. Then the car pulled over and two men got out.
The federal immigration officials told him not to run. They then peppered Gutiérrez with questions: Where are you going? Where are you coming from? Do you have your ID on you?
Gutiérrez is a U.S. citizen. He told the officials this. He didn’t have any identification on him, but, panicking, he tried to find a copy on his phone. The agents put him into the car, where another two agents were waiting, and handcuffed him. Just sit there and be quiet, they said.
Without Gutiérrez’s ID, the agents resorted to another approach. They took a photo of his face. A short while later, the agents got their answer: “Oh yeah, he’s right. He’s saying the right thing. He does got papers,” Gutiérrez recalled the agents saying.

This is Behind the Blog, where we share our behind-the-scenes thoughts about how a few of our top stories of the week came together. This week, we discuss conversational AI, a behind the scenes of the zine, and more.
EMANUEL: I made the terrible mistake of looking at some Hacker News comments this week for my story about a developer whose Google accounts were banned after he uploaded training data to Google Drive. Unbeknownst to him, the training data contained CSAM.
As we’ve explained in previous stories, CSAM is a subject we dread covering not only because it’s one of the most awful things one could think about, but because it’s extremely difficult and legally risky. For understandable reasons, the laws around viewing, let alone possessing CSAM, are strict and punishing, which makes verification for reporting reasons challenging. For similar reasons, it’s something we need to write about very carefully, making sure we don’t wrongfully associate or whitewash someone when it comes to such horrible behavior.

The degenerate gamblers of Polymarket and Kalshi who bet that “AI” would win the Time Person of the Year are upset because the magazine has named the “Architects of AI” the person of the year. The people who make AI tools and AI infrastructure are, notably, not “AI” themselves, and thus both Kalshi and Polymarket have decided that people who bet “AI” do not win the bet. On Polymarket alone, people spent more than $6 million betting on AI gracing the cover of Time.
As writer Parker Molloy pointed out, people who bet on AI are pissed. “ITS THE ARCHITECTS OF AI THISNIS [sic] LITERALLY THE BET FUCK KALSHI,” one Kalshi better said.

The first thing I saw this morning when I opened X was an AI-generated trailer for Avengers: Doomsday. Robert Downey Jr’s Doctor Doom stood in a shapeless void alongside Captain America and Reed Richards. It was obvious slop but it was also close in tone and feel of the last five years of Disney’s Marvel movies. As media empires consolidate, nostalgia intensifies, and AI tools spread, Disney’s blockbusters feel more like an excuse to slam recognizable characters together in a contextless morass.

Dozens of government and university websites belonging to cities, towns, and public agencies across the country are hosting PDFs promoting AI porn apps, porn sites, and cryptocurrency scams; dozens more have been hit with a website redirection attacks which lead to animal vagina sex toy ecommerce pages, penis enlargement treatments, automatically-downloading Windows program files, and porn.
“Sex xxx video sexy Xvideo bf porn XXX xnxx Sex XXX porn XXX blue film Sex Video xxx sex videos Porn Hub XVideos XXX sexy bf videos blue film Videos Oficial on Instagram New Viral Video The latest original video has taken the internet by storm and left viewers in on various social media platforms ex Videos Hot Sex Video Hot Porn viral video,” reads the beginning of a three-page PDF uploaded to the website of the Irvington, New Jersey city government’s website.
The PDF, called “XnXX Video teachers fucking students Video porn Videos free XXX Hamster XnXX com” is unlike many of the other PDFs hosted on the city’s website, which include things like “2025-10-14 Council Minutes,” “Proposed Agenda 9-22-25,” and “Landlord Registration Form (1 & 2 unit dwelling).”
It is similar, however, to another PDF called “30 Best question here’s,” which looks like this:
Irvington, which is just west of Newark and has a population of 61,000 people, has fallen victim to an SEO spam attack that has afflicted local and state governments and universities around the United States.
Researcher Brian Penny has identified dozens of government and university websites that hosted PDF guides for how to make AI porn, PDFs linking to porn videos, bizarre crypto spam, sex toys, and more.
Reginfo.gov, a regulatory affairs compliance website under the federal government’s General Services Administration, is currently hosting a 12 page PDF called “Nudify AI Free, No Sign-Up Needed!,” which is an ad and link to an abusive AI app designed to remove a person’s clothes. The Kansas Attorney General’s office and the Mojave Desert Air Quality Management District Office in California hosted PDFs called “DeepNude AI Best Deepnude AI APP 2025.” Penny found similar PDFs on the websites for the Washington Department of Fish and Wildlife, the Washington Fire Commissioners Association, the Florida Department of Agriculture, the cities of Jackson, Mississippi and Massillon, Ohio, various universities throughout the country, and dozens of others. Penny has caught the attention of local news throughout the United States, who have reported on the problem.
The issue appears to be stemming from websites that allow people to upload their own PDFs, which then sit on these government websites. Because they are loaded with keywords for widely searched terms and exist on government and university sites with high search authority, Google and other search engines begin to surface them. In the last week or so, many (but not all) of the PDFs Penny has discovered have been deleted by local governments and universities.
But cities seem like they are having more trouble cleaning up another attack, which is redirecting traffic from government URLs to porn, e-commerce, and spam sites. In an attack that seems similar to what we reported in June, various government websites are somehow being used to maliciously send traffic elsewhere. For example, the New York State Museum’s online exhibit for something called “The Family Room” now has at least 11 links to different types of “realistic” animal vagina pocket masturbators, which include “Zebra Animal Vagina Pussy Male Masturbation Cup — Pocket Realistic Silicone Penis Sex Toy ($27.99),” and “Must-have Horse Pussy Torso Buttocks Male Masturbator — Fantasy Realistic Animal Pussie Sex Doll.”
Links Penny found on Knoxville, Tennessee’s site for permitting inspections first go to a page that looks like a government site for hosting files then redirects to a page selling penis growth supplements that features erect penises (human penises, mercifully), blowjobs, men masturbating, and Dr. Oz’s face.
Another Knoxville link I found, which purports to be a pirated version of the 2002 Vin Diesel film XXX simply downloaded a .exe file to my computer.
Penny believes that what he has found is basically the tip of the iceberg, because he is largely finding these by typing things like “nudify site:.gov” “xxx site:.gov” into Google and clicking around. Sometimes, malicious pages surface only on image searches or video searches: “Basically the craziest things you can think of will show up as long as you’re on image search,” Penny told 404 Media. “I’ll be doing this all week.”
The Nevada Department of Transportation told 404 Media that “This incident was not related to NDOT infrastructure or information systems, and the material was not hosted on NDOT servers.This unfortunate incident was a result of malicious use of a legitimate form created using the third-party platform on which NDOT’s website is hosted. NDOT expeditiously worked with our web hosting vendor to ensure the inappropriate content was removed.” It added that the third-party is Granicus, a massive government services company that provides website backend infrastructure for many cities and states around the country, as well as helps them stream and archive city council meetings, among other services. Several of the affected local governments use Granicus, but not all of them do; Granicus did not respond to two requests for comment from 404 Media.
The California Secretary of State’s Office told 404 Media: “A bad actor uploaded non-business documents to the bizfile Online system (a portal for business filings and information). The files were then used in external links allowing public access to only those uploaded files. No data was compromised. SOS staff took immediate action to remove the ability to use the system for non-SOS business purposes and are removing the unauthorized files from the system.” The Washington Department of Fish and Wildlife said “WDFW is aware of this issue and is actively working with our partners at WaTech to address it.” The other government agencies mentioned in this article did not respond to our requests for comment.
