Welcome back to the Abstract! Here are the studies this week that rolled with it, went out on a limb, gravitationally waved, and spotted relics in our midst.
First, hundreds of prehistoric dice sets shed light on the dawn of gambling. Then: these disembodied arms are horny, the forbidden fruits of supernovae, and baby food for the Milky Way.

Thousands of years before prediction markets, sports betting, and poker nights, Native Americans were playing the odds with dice and other games of chance.
An analysis of nearly 300 ancient artifacts related to gambling—especially two-sided dice known as “binary lots”—has revealed that Native Americans have played games of chance for at least 12,000 years, many millennia before any other known cultures in the world.
“Historians of mathematics frequently identify the invention of dice and games of chance as a crucial early step in humanity’s evolving discovery and understanding of randomness and the probabilistic nature of the universe,” said study author Robert Madden of Colorado State University.
“The findings presented here suggest that some of the earliest steps on this intellectual journey were taken not by complex societies in the Near East and Eastern Europe around 5,500 years ago but rather by Native American hunter-gatherers in western North America in the waning centuries of the Pleistocene, no later than 12,000 years ago,” he continued.
Scholars have marveled at the prevalence of Native American games of chance for more than a century, but Madden is the first to systematically trace their origins. He set out to study prehistoric dice in museum collections at the Smithsonian Institution, the University of Wyoming Archaeological Repository, and the Denver Museum of Nature and Science, which were documented in a landmark compendium called Games of the North American Indians published in 1907 by the ethnographer Stewart Culin.
The most common dice games involved players taking turns throwing sets of binary lots, with a score that was assigned based on a count of the “up”-facing side thrown by each player on their turn. Cumulative scores were tracked with counting sticks; the first to reach a predesignated number were the winners.
Madden identified dice at 57 archaeological sites across 12 states, with the oldest appearing in the territories of western Great Plains cultures. The finds clearly indicate a complex understanding of probability, which played a role not only in social cohesion, but also in cosmologies.
“Numerous ethnographic accounts of Native American traditions depict dice playing as a sacred activity that was inherently pleasing to the gods and celestial powers (who were themselves dice players), with ceremonial and secular dice games being played at festivals and seasonal events,” Madden said.
The study chronicles many fascinating myths and legends about gods playing dice on the surface of Earth and the creation of humans as the outcome of a cosmic dice game. Albert Einstein famously remarked that god “does not throw dice” in response to the probabilistic realm of quantum physics. It would seem these prehistoric cultures were way ahead of the game on this point.

Villar, Pablo S., Jiang, Hao et al. “A sensory system for mating in octopus.” Science.
Male octopuses are real suckers for sex, reports a new study about the “hectocotylus,” which is a special arm that serves a dual purpose as both sensory and mating organ.
During copulation, males use the hectocotylus to probe the female’s intricate oviducts in order to deposit sperm, but the mechanisms behind this strategy have been shrouded in tentacled mystery. To get a better handle on the process, scientists coated tubes with different substances and discovered that octopuses only released sperm when sucker cups on the hectocotylus made contact with progesterone, a female hormone produced in the ovaries.
“Whereas nonmating arms are used for chemotactile exploration and predation, the hectocotylus is almost exclusively used for mating and often even protected during hunting,” said researchers co-led by Pablo S. Villar of Harvard University and Hao Jiang of the University of California San Diego.
In a wild twist, the hectocotylus can even work its magic when it is entirely severed from the male’s body, allowing detached arms to autonomously inseminate females! It’s proof that romance is not dead, it’s just occasionally dismembered.
Tong, Hui et al. “Evidence of the pair-instability gap from black-hole masses.” Nature.
You’ve heard of forbidden planets, but what about forbidden black holes? For years, scientists have theorized that black holes with masses between approximately 50 and 130 times the mass of the Sun fall into a “forbidden range” that cannot exist.
The reason is that colossal stars that are 100 to 260 times more massive than the Sun experience a special kind of stellar death known as “pair‑instability supernovae” in which they completely self-destruct, preventing the formation of black holes. Stars that are both bigger and smaller than this range, in contrast, explode in supernovae that do collapse into black holes.
Now, scientists have discovered evidence for this gap using dozens of gravitational waves, which are ripples in spacetime formed by cataclysmic events such as mergers of black holes. In binary black holes—systems where two of these massive objects orbit each other—the smaller objects never fell into this range. Some of the larger black holes had forbidden masses, but that’s likely because they had merged with other black holes in the past, not because they were initially at that mass after the deaths of their progenitor stars.
“We interpret these findings as evidence for a subpopulation of hierarchical mergers: binaries in which the primary component is the product of a previous black-hole merger and thus populates the gap,” said researchers led by Hui Tong of Monash University. “As the number of detections increases, it will be possible to gain new insights into the pair-instability gap.”
From my perspective, all black holes are forbidden, because they are terrifying cosmic death traps. But it’s nice to know that the universe has limits, too.
Last, it’s time to pay respect to our stellar elders. A new study reveals that a weird population of 20 stars orbiting within a few thousand light years of the Sun have basically no metals, the astronomical term for elements that are heavier than hydrogen and helium. Since new generations of stars become more enriched with metals over time, these stars must be extremely ancient relics. So where did they come from?
Scientists think they have the answer: These metal-light Methusalehs are the last remnants of an ancient dwarf galaxy, which the team dubs “Loki.” Despite its powerful Norse namesake, Loki appears to have been swallowed by the Milky Way early on in our galaxy’s 13-billion-year history. While it is common to find very metal-poor (VMP) stars orbiting all around our galaxy’s core, it’s much rarer to find them all the way out here in the galactic exurbs, hidden in the “plane” (the flattened disk of a galaxy).
“This work provides, for the very first time, a dedicated detailed chemical abundance analysis of a sample of VMP stars with orbits close to the Milky Way plane,” said researchers led by Federico Sestito of the University of Hertfordshire. “A plausible scenario, supported by cosmological zoom-in simulations, is the early accretion of a single system.”
It goes without saying that eating a whole galaxy is pretty metal, even if the stars within it are not.

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 crypto, journalists using AI, and a cool photo of Earth.
JOSEPH: I can’t talk about the story just yet, but recently I had to acquire some cryptocurrency quickly for research purposes. I was not anticipating quite how dramatically the world of cryptocurrency and getting it has changed.
I first became aware of cryptocurrency, or more specifically Bitcoin, when I was an intern at VICE. Someone on my table (they put all the unpaid interns on a medium sized table in the London office) was talking about it. They were pretty deep into it as I recall, and covered it a fair bit. I then was asked to work on a collaborative documentary between VICE, Raw, and the BBC about the Silk Road drug marketplace because I already knew more than most about message encryption. I then had to learn more about Bitcoin.

Minnesota photojournalist Rob Levine and the Reporters Committee for Freedom of the Press are suing the Federal Aviation Administration over a recently issued restriction that prevents drones from flying within 3,000 feet of Department of Homeland Security buildings and vehicles, an amorphous no-fly zone that encompasses Immigrations and Customs Enforcement agents.
The FAA issued the temporary flight restriction (TFR) in January as ICE agents flooded the streets of Minneapolis. The rule established a no fly zone of 3,000 feet around “Department of Homeland Security facilities and mobile assets,” a restriction that Levine and his lawyers argue is impossible to follow and is aimed at curtailing the First Amendment rights of journalists.
“Because there is no means of verifying in advance whether DHS vehicles—such as unmarked cars driven by Immigration and Customs Enforcement agents—are operating in a given location, the practical consequence is that drone pilots nationwide cannot know whether a flight will expose them to liability,” Levine’s lawyers argued in a court document.
Levine lives in Minneapolis and spent the early days of Operation Metro Surge using his drone to capture footage of protests and ICE agents. Then the TFR hit. “It sent a shiver down my spine,” he told 404 Media. “I’m like ‘Oh my god.’ In a city like Minneapolis at the time with, I don’t know, three or four thousand DHS agents in various stages of uniform or undercoverness or civilian cars that they had switched license plates on? Masquerading as delivery men? They were everywhere here. I immediately grounded myself because there was no way you could know in advance whether or not you were violating that [flight restriction]. And when you’re flying they could drive by and you might not even know it.”
Grayson Clary, a lawyer with Reporters Committee for Freedom of the Press who is representing Levine, told 404 Media that the FAA has previously used flight restrictions in ways that seem designed to prevent newsgathering. “The FAA has a long history of imposing these temporary flight restrictions over newsworthy events in ways that frustrate journalists' ability to cover protests, law enforcement's response to protests, you name it, and this is sort of the newest escalation in that story,” he said.
This new no fly zone is a modification of an old TFR from 2025 that restricted drone pilots from operating within 3,000 feet of Department of Defense and Department of Energy bases.
“When you think about the old restriction, it’s essentially don’t fly within 3,000 feet of an enormous Naval vessel or a Department of Energy convoy that’s ferrying nuclear weapons around,” Clary said. “They just sort of added DHS to the end of that without taking stock of just how much more difficult it is to know whether you’re within 3,000 feet of a DHS ground vehicle as opposed to within 3,000 feet of a destroyer sitting in a Naval base.”
DHS isn’t forthcoming about the number of ICE agents in a given city or where they are operating. They often wear plainclothes, patrol cities in unmarked vehicles, and don’t announce themselves to people in the neighborhoods they patrol. Clary and Levine argued that the secretive nature of DHS has made it impossible for journalists to comply with the FAA’s no fly zone.
The penalties for violating the FAA restriction are severe. “They can take your drone and destroy it. They could shoot it down if they wanted to. They can arrest you and throw you in jail…and they can also make it so you can never fly a drone again,” Levine said. “It seems purely to prevent photo journalism and to chill photo journalists because the rule is so vague they could even charge you after the fact if they determined that you were somewhere and they had been near there.” The FAA has a history of trying to enforce drone restrictions against operators after the fact, based on footage or images posted on YouTube or social media sites.
Clary agreed. “That’s part of what makes this such a First Amendment problem is that it has a real chilling effect. When you don't know where exactly the line is, you're going to play it more carefully to make sure that you don't accidentally cross it,” he said.
Levine has fought the FAA before on this issue and won. In 2016, just as he was first learning how to pilot drones for his photojournalism work, he traveled to North Dakota to cover the anti-oil pipeline protests at Standing Rock. At the time, the FAA had issued a TFR over the area but Levine was able to push the agency into granting him a waiver on First Amendment grounds.
DHS operates its own drones to aid its surveillance efforts. Last year it flew Predator drones above protests in Los Angeles and Minneapolis residents have taken a lot of footage capturing drones flying above homes in Minnesota.

In 1969, the three astronauts of the Apollo 10 mission conducted a momentous “dress rehearsal” for putting humans on the lunar surface for the first time. It was a historic, inspiring moment for humanity; Astronaut John Young watched from a command module spacecraft as Thomas Stafford and Gene Cernan broke away and flew a lunar module within 10 miles of the moon’s surface, then reunited to return home to Earth. It’s from this mission that we have one of the most powerful transcripts in NASA history:
“Who did what?” Young asked. “Where did that come from?” Cernan added.
“Give me a napkin quick,” Stafford said. “There’s a turd floating through the air.”
The provenance of the poop remains one of the great mysteries of spaceflight. Today, in the early Earth-morning hours of the Artemis II astronauts’ history-mirroring mission around the moon, we have another: Why is Microsoft Outlook not working in space?

TeleGuard, an app that markets itself as a secure, end-to-end encrypted messaging platform which has been downloaded more than a million times, implements its encryption so poorly that an attacker can trivially access a user’s private key and decrypt their messages, multiple security researchers told 404 Media. TeleGuard also uploads users’ private keys to a company server, meaning TeleGuard itself could decrypt its users’ messages, and the key can also at least partially be derived from simply intercepting a user’s traffic, the researchers found.
The news highlights something of the wild west of encrypted messaging apps, where not all are created equal.
“No storage of data. Highly encrypted. Swiss made,” the website for TeleGuard reads. The site also says, “The chats as well as voice and video calls are end-to-end encrypted.”

Scientists have engineered tobacco plants to produce five psychedelic compounds that are normally found in a wide range of natural sources, including psilocybin mushrooms, ayahuasca, and toads, according to a study published on Wednesday in Science Advances.
The breakthrough could lead to more sustainable and scalable production of these compounds by using model plants to biosynthesize common psychedelic “tryptamines,” such as psilocybin from hallucinogenic mushrooms, N,N-Dimethyltryptamine (DMT) from plants, and psychoactive compounds secreted by the Sonoran Desert toad.
Eventually, this research could pave the way toward—as one example—tomato plants that contain microdoses of psychedelic cocktails in each fruit. However, the study’s authors emphasized that these modified plants would need to be limited to medical use in clinical settings, and should not be accessible to consumers for recreation.
“We are interested in this, not because of the recreational effects, but because of the medicinal potential,” said Paula Berman, a postdoctoral researcher at the Weizmann Institute of Science who co-led the study, in a call with 404 Media.
“This combination of five psychedelics—I don't think anyone has ever tried something like it,” added senior author Asaph Aharoni, principal investigator and head of the department of plant and environmental sciences at the Weizmann Institute of Science, in the same call.
Tryptamines are a subclass of metabolites—compounds produced by metabolic processes in organisms—which have wide-ranging potential as treatments for conditions such as depression, anxiety, mood disorders, and post-traumatic stress disorder.
Indigenous cultures in many regions have cultivated tryptamines for thousands of years for ritual, spiritual, and therapeutic purposes. These compounds are now in high demand as both recreational drugs and medicinal treatments, though legal regulations governing their use vary widely around the world.
Due to their growing popularity, many of the source organisms that produce these compounds are facing significant ecological stresses in the wild; for example, the Sonoran Desert toad population is rapidly declining due to poaching and over-harvesting. Scientists have produced synthetic versions of some tryptamines, but those methods often involve complicated processing steps and hazardous reactants that generate chemical waste.
To help alleviate these problems, Berman, Aharoni, and their colleagues reconstructed the biosynthetic pathways in five tryptamines: Psilocin and psilocybin, both found in hallucinogenic mushrooms; DMT, which is the psychoactive part of ayahuasca; and the psychedelic compounds bufotenin and 5-methoxy-DMT secreted by the Sonoran Desert toad.
The team then inserted the active genes of these pathways into the leaves of a tobacco plant, creating a botanical platform to produce all five psychedelics. By design, the modified plants are not able to pass these genes onto future generations, as this study is intended to offer a “proof of concept,” Berman said.
“In one leaf, we get five different psychedelics from three different kingdoms,” said Aharoni. “But since it is not inherited, it will stay in the leaves and will not go through to seeds, flowering, pollination, and to the next generation.”
“One reason that we did that is we are still not sure if we want to make plants where everybody can grab seeds from us and grow a plant with five different compounds” that might be deadly, he added. “We have to make sure that it stays in research.”
With that caveat, the team hopes that their work could lead to a method of tryptamine biosynthesis that could help meet the global demand for these compounds. In addition to sidestepping the disadvantages of synthetic versions, this technique could also remove stressors on wild populations. The goal is to ensure that wild tryptamine sources can be reserved for use in traditional Indigenous practices.
The researchers are also interested in clarifying the evolutionary purpose of psychedelic compounds for the plants that naturally produce them, which remains mysterious in many cases.
“We understand the importance of the plants, the fungi, and the Sonoran Desert toad, and every species that we discuss in the paper,” Berman said. “One of our motivations was to really understand better what these species do, so that we can mimic what they do.”
“Over-harvesting endangers the natural availability of these species for native peoples and Indigenous groups,” she concluded. “We have so much respect for the knowledge that they provide us, and we just want to add to this knowledge and to be able to produce these in a more sustainable way.”
