Easter Island’s Moai Statues May Have Walked to Where They Now Stand


Easter Island statues, traditionally known as moai on the remote island of Rapa Nui in the South Pacific, are some of the most impressive artifacts of ancient Polynesian civilization. How the statues were transported has long remained a conundrum, because they can weigh up to several tons yet are scattered throughout the island. Various theories have been proposed, including that they were dragged on wooden sleds or rolled along the ground, but no supportive evidence has backed those claims.

In 2012, a US research team succeeded in propping up a 4.35-ton replica of a moai statue and making it “walk.” The technique, in which two teams using ropes tugged the statue in opposite directions to teeter it forward while a third team ensured it wouldn’t topple over, challenged the conventional theories that moai were moved in a horizontal position.

The question then is how much effort it would have taken to move much larger moai. “Once the moai are in motion, it’s not at all difficult,” explained Carl Lipo, an anthropologist at Binghamton University.

Lipo and his team systematically surveyed 962 moai statues on Easter Island, focusing primarily on 62 found along ancient roads. They recently published a paper providing strong evidence that moai were transported in an upright position.

The team also succeeded in moving an exact replica of roadside moai 100 meters in 40 minutes with only 18 people, a far more efficient result than those of previous experiments.

Researchers demonstrate how the Rapa Nui people may have “walked” moai.

Rules of the Road

The study discovered that moai statues positioned along Rapa Nui’s roads have common characteristics. The broad D-shaped base and forward leaning design of the statues optimized the moai for “walking,” even as they increased in size. In fact, moai abandoned by the side of the road were found to have imbalanced centers of gravity and show signs of toppling over during transport.

This hypothesis is also supported by the ancient roads themselves, which are approximately 4.5 meters wide and have slightly concave cross-sections. Researchers believe these were ideal conditions to aid in stabilizing the moai as they were walked.

A statistical analysis of the distribution of moai showed 51.6 percent were concentrated within 2 km of the quarry where they originated, demonstrating an exponential decay pattern associated with mechanical failure rather than deliberate ceremonial placement. It’s likely these statues were damaged or fell over during transport and left where they lay.

The Tovala Oven and Meal Kit Is Like a Robot Chef of Future Past

The Tovala Oven and Meal Kit Is Like a Robot Chef of Future Past


A garlic-herb salmon with risotto was probably the best among the family meals I tried. The chopped asparagus was less than visually appealing when drizzled in garlic butter, but still tasty and a bit crisp. The salmon was tender and flaky. And the sweet pea risotto had no choice but to be delicious. There was so much cheese, butter, and lemon it was pretty much a concert of fats and acid.

That chicken parm was likewise a mountain of cheese and salt. It reminded me, pleasantly, of countless family meals I had as a child in the 1980s: cheese-topped chicken, garlic bread, shells stuffed with ricotta and topped with even more cheese. The big difference is that there is simply no way my mother would have cooked this meal without a vegetable.

And nutrition is where Toval runs aground a little. The nutritional notes on that chicken parm meal betray 2,300 milligrams of sodium per serving, pretty much the entire daily allowance for an adult human. This is also on par with comparable servings of Stouffer’s meat lasagna. The Tovala meal also carried about 10 times the cholesterol as Stouffer’s.

Many other meals followed a similar pattern, loading up on fats and salt in order to make meals tasty. The net effect is that it’s a lot more like rich restaurant food than what most people prepare at home. Whether this is a good or a bad quality is up to you.

Only one meal of the seven I tried failed utterly: I flagged a teriyaki chicken dinner to my editor as a possible cultural crime against Japan. The meal was sweet soy drenching pale and steaming chicken, with an implausible side of thick egg rolls and some loose, unseasoned broccoli. It felt like the “Japanese” food you’d get at a mall food court in the ’90s. But again, this was a rare major misstep.

A more pernicious issue, in meals designed for the whole family, is the near-universal high-fat, cholesterol, and sodium content. Many with the income and inclination to eat hearty, low-effort meals like the ones from Tovala are either parents with children, or people in the retirement bracket. Each has their own reason to desire a little more nutrition, and less fat and salt.

By the end of a couple of weeks of testing recipes, I’ll admit I felt a little relieved. I was grateful to feel my arteries slowly reopen. Tovala’s culinary model makes a lot of sense to me, as a smart way of splitting the difference between prepared meals and fresh food. And the company has proven it can cook well. It might be nice if they’d also cook a diet that felt more sustainable.

Waymo Is Trying to Crack Down on Solo Kids in Driverless Cars

Waymo Is Trying to Crack Down on Solo Kids in Driverless Cars


By law, autonomous vehicles aren’t legally allowed to carry unaccompanied minors in California. Waymo, Alphabet’s self-driving car company, doesn’t allow kids under 18 to ride alone anywhere outside of metro Phoenix, Arizona. But that hasn’t stopped some time-strapped parents from using their own accounts to transport their kids to school, extracurricular activities, and even social outings. Some have reported that the lack of drivers makes them feel safer.

Waymo is working to crack down on the practice, the company confirmed Friday, after reports of new mid-ride age-verification checks began to float around on social media. The company has “policies in place” to help it identify violations of its terms of service, Waymo spokesperson Chris Bonelli wrote in a statement to WIRED. “We are continuing to refine our system and processes for accuracy over time.” Violating its terms of service can lead to temporary or permanent suspension of an account, Waymo says.

The company uses cameras inside its cars to check that riders aren’t violating its rules. Its privacy policy notes that the company records video inside the vehicle during trips. Waymo says its support workers “may review video under certain circumstances,” and, “in more urgent circumstances,” access live video during a trip. The company says it does not use facial recognition or “other biometric identification technologies” to identify individuals.

The news comes a month after several California labor groups, including the California Gig Workers Union, filed a formal complaint with a state regulatory agency, accusing Waymo of violating the terms of its permit to operate in the state by knowingly transporting unaccompanied minors. The matter was assigned to a judge this week. The state is evaluating new rules that could allow solo riders under 18 in driverless cars, perhaps patterned after a program that permits ride-hail companies with human drivers to transport minors in California.

So far, several fresh-faced adults have been caught in the crossfire. On Tuesday, San Francisco machine learning engineer Nicholas Fleischhauer was about five minutes into his Waymo ride when the car connected him to support. A voice came over the line asking Fleischhauer to verify his age. He told the worker the truth: He’s 35. “I had messy and wet hair, and a backpack on me,” he says, by way of explaining why he might have been flagged by Waymo’s system. Plus, “people have told me that I look young for my age.” Fleischhauer says he takes Waymo weekly, but this marked the first time he had been asked about his age.

Since last summer, Waymo has allowed parents in the Phoenix area to set up teen accounts for riders ages 14 to 17. The accounts allow the teen riders’ adults to track their real-time locations during their trips. Waymo says a specially trained team of support agents deals with any issues its teen riders might have. Waymo says that “hundreds” of Phoenix families use the service each week.

In Waymo’s other markets across the US, adults are allowed to ride with guests under 18, though children under 8 must be in a secured car or booster seat.

Ethan S. Klein is 23, but his 26th LA Waymo ride on Thursday—plus the music he was listening to—was interrupted by an in-car call from a support agent who asked him, for the first time, to verify his birth date. Klein is an adult, but his first impulse was almost teen-like. “I was a little startled,” he says. “I thought I was in trouble!”

Dangerous New Linux Exploit Gives Attackers Root Access to Countless Computers

Dangerous New Linux Exploit Gives Attackers Root Access to Countless Computers


Publicly released exploit code for an effectively unpatched vulnerability that gives root access to virtually all releases of Linux is setting off alarm bells as defenders scramble to ward off severe compromises inside data centers and on personal devices.

The vulnerability and exploit code that exploits it were released Wednesday evening by researchers from security firm Theori, five weeks after privately disclosing it to the Linux kernel security team. The team patched the vulnerability in versions 7.0, 6.19.12, 6.18.12, 6.12.85, 6.6.137, 6.1.170, 5.15.204, and 5.10.254) but few of the Linux distributions had incorporated those fixes at the time the exploit was released.

A Single Script to Hack Them All

The critical flaw, tracked as CVE-2026-31431 and the name CopyFail, is a local privilege escalation, a vulnerability class that allows unprivileged users to elevate themselves to administrators. CopyFail is particularly severe because it can be exploited with a single piece of exploit code—released in Wednesday’s disclosure—that works across all vulnerable distributions with no modification. With that, an attacker can, among other things, hack multi-tenant systems, break out of containers based on Kubernetes or other frameworks, and create malicious pull requests that pipe the exploit code through CI/CD work flows.

“‘Local privilege escalation’ sounds dry, so let me unpack it,” researcher Jorijn Schrijvershof wrote Thursday. “It means: An attacker who already has some way to run code on the machine, even as the most boring unprivileged user, can promote themselves to root. From there they can read every file, install backdoors, watch every process, and pivot to other systems.”

Schrijvershof added that the same Python script Theori released works reliably for Ubuntu 22.04, Amazon Linux 2023, SUSE 15.6, and Debian 12. The researcher continued:

Why does that matter on shared infrastructure? Because “local” covers a lot of ground in 2026: every container on a shared Kubernetes node, every tenant on a shared hosting box, every CI/CD job that runs untrusted pull-request code, every WSL2 instance on a Windows laptop, every containerised AI agent given shell access. They all share one Linux kernel with their neighbors. A kernel LPE collapses that boundary.

The realistic threat chain looks like this. An attacker exploits a known WordPress plugin vulnerability and gets shell access as www-data. They run the copy.fail PoC. They are now root on the host. Every other tenant is suddenly reachable, in the way I walked through in this hack post-mortem. The vulnerability does not get the attacker onto the box; it changes what happens in the next ten seconds after they land there.

The vulnerability stems from a “straight-line” logic flaw in the kernel’s crypto API. Many exploits exploiting race conditions and memory corruption flaws don’t consistently succeed across kernel versions or distributions, and sometimes even on the same machine. Because the code released for CopyFail exploits a logic flaw, “reliability isn’t probabilistic, and the same script works across distributions, researchers from Bugcrowd wrote. “No race window, no kernel offset.”

CopyFail gets its name because the authencesn AEAD template process (used for IPsec extended sequence numbers) doesn’t actually copy data when it should. Instead, it “uses the caller’s destination buffer as a scratch pad, scribbles 4 bytes past the legitimate output region, and never restores them,” Theori said. “The ‘copy’ of the AAD ESN bytes ‘fails’ to stay inside the destination buffer.”

The Worst Linux Vulnerability in Years

Other security experts echoed the perspective that CopyFail poses a serious threat, with one saying it’s the “worst make-me-root vulnerabilities in the kernel in recent times.”

The most recent such Linux vulnerability was Dirty Pipe from 2022 and Dirty Cow in 2016. Both of those vulnerabilities were actively exploited in the wild.
