brazenly out in the open —

Cybercriminals openly run dozens of scams across social media and messaging apps.

Most scammers and cybercriminals operate in the digital shadows and don’t want you to know how they make money. But that’s not the case for the Yahoo Boys, a loose collective of young men in West Africa who are some of the web’s most prolific—and increasingly dangerous—scammers.

Thousands of people are members of dozens of Yahoo Boy groups operating across Facebook, WhatsApp, and Telegram, a WIRED analysis has found. The scammers, who deal in types of fraud that total hundreds of millions of dollars each year, also have dozens of accounts on TikTok, YouTube, and the document-sharing service Scribd that are getting thousands of views.

Inside the groups, there’s a hive of fraudulent activity with the cybercriminals often showing their faces and sharing ways to scam people with other members. They openly distribute scripts detailing how to blackmail people and how to run sextortion scams—that have driven people to take their own lives—sell albums with hundreds of photographs, and advertise fake social media accounts. Among the scams, they’re also using AI to create fake “nude” images of people and real-time deepfake video calls.

The Yahoo Boys don’t disguise their activity. Many groups use “Yahoo Boys” in their name as well as other related terms. WIRED’s analysis found 16 Yahoo Boys Facebook groups with almost 200,000 total members, a dozen WhatsApp channels, around 10 Telegram channels, 20 TikTok accounts, a dozen YouTube accounts, and more than 80 scripts on Scribd. And that’s just the tip of the iceberg.

Broadly, the companies do not allow content on their platforms that encourages or promotes criminal behavior. The majority of the Yahoo Boys accounts and groups WIRED identified were removed after we contacted the companies about the groups’ overt existence. Despite these removals, dozens more Yahoo Boys groups and accounts remain online.

“They’re not hiding under different names,” says Kathy Waters, the co-founder and executive director of the nonprofit Advocating Against Romance Scammers, which has tracked the Yahoo Boys for years. Waters says the social media companies are essentially providing the Yahoo Boys with “free office space” to organize and conduct their activities. “They’re selling scripts, selling photos, identifications of people, all online, all on the social media platforms,” she says. “Why these accounts still remain is beyond me.”

The Yahoo Boys aren’t a single, organized group. Instead, they’re a collection of thousands of scammers who work individually or in clusters. Often based in Nigeria, their name comes from formerly targeting users of Yahoo services, with links back to the Nigerian Prince email scams of old. Groups in West Africa can be often organized in various confraternities, which are cultish gangs.

“Yahoo is a set of knowledge that allows you to conduct scams,” says Gary Warner, the director of intelligence at DarkTower and director of the University of Alabama at Birmingham’s Computer Forensics Research Laboratory. While there are different levels of sophistication of Yahoo Boys, Warner says, many simply operate from their phones. “Most of these threat actors are only using one device,” he says.

The Yahoo Boys run dozens of scams—from romance fraud to business email compromise. When making contact with potential victims, they’ll often “bomb” people by sending hundreds of messages to dating app accounts or Facebook profiles. “They will say anything they can in order to get the next dime in their pocket,” Waters says.

Searching for the Yahoo Boys on Facebook brings up two warnings: Both say the results may be linked to fraudulent activity, which isn’t allowed on the website. Clicking through the warnings reveals Yahoo Boy groups with thousands of members—one had more than 70,000.

Within the groups—alongside posts selling SIM cards and albums with hundreds of pictures—many of the scammers push people toward other messaging platforms such as Meta’s WhatsApp or Telegram. Here, the Yahoo Boys are at their most bold. Some groups and channels on the two platforms receive hundreds of posts per day and are part of their wider web of operations.

After WIRED asked Facebook about the 16 groups we identified, the company removed them, and some WhatsApp groups were deactivated. “Scammers use every platform available to them to defraud people and constantly adapt to avoid getting caught,” says Al Tolan, a Meta spokesperson. They did not directly address the accounts that were removed or that they were easy to find. “Purposefully exploiting others for money is against our policies, and we take action when we become aware of it,” Tolan says. “We continue to invest in technology and cooperate with law enforcement so they can prosecute scammers. We also actively share tips on how people can protect themselves, their accounts, and avoid scams.”

Groups on Telegram were removed after WIRED messaged the company’s press office; however, the platform did not respond about why it had removed them.

Across all types of social media, Yahoo Boys scammers share “scripts” that they use to socially manipulate people—these can run to thousands of words long and can be copied and pasted to different victims. Many have been online for years. “I’ve seen some scripts that are 30 and 60 layers deep, before the scammer actually would have to go and think of something else to say,” says Ronnie Tokazowski, the chief fraud fighter at Intelligence for Good, which works with cybercrime victims. “It’s 100 percent how they’ll manipulate the people,” Tokazowski says.

Among the many scams, they pretend to be military officers, people offering “hookups,” the FBI, doctors, and people looking for love. One “good morning” script includes around a dozen messages the scammers can send to their targets. “In a world full of deceit and lies, I feel lucky when see the love in your eyes. Good morning,” one says. But things get much darker.

Swimming and spinning aquatic spiders use slick survival strategies

Spider (He is our hero) —

Some make nests inside seashells, others tote bubbles of air on their backs.

–

Diving bell spider

Enlarge / Of all the aquatic spiders, the diving bell spider is the only one known to survive almost entirely underwater, using bubbles of air it brings down from the surface.

Shrubbery, toolsheds, basements—these are places one might expect to find spiders. But what about the beach? Or in a stream? Some spiders make their homes near or, more rarely, in water: tucking into the base of kelp stalks, spinning watertight cocoons in ponds or lakes, hiding under pebbles at the seaside or creek bank.

“Spiders are surprisingly adaptable, which is one of the reasons they can inhabit this environment,” says Ximena Nelson, a behavioral biologist at the University of Canterbury in Christchurch, New Zealand.

Finding aquatic or semiaquatic spiders is difficult work, Nelson says: She and a student have spent four years chasing a jumping spider known as Marpissa marina around the pebbly seaside beaches it likes, but too often, as soon as they manage to find one it disappears again under rocks. And sadly, some aquatic spiders may disappear altogether before they come to scientists’ attention, as their watery habitats shrivel due to climate change and other human activities.

What scientists do know is that dozens of described spider species spend at least some of their time in or near the water, and more are almost surely awaiting discovery, says Sarah Crews, an arachnologist at the California Academy of Sciences in San Francisco. It also appears that spiders evolved aquatic preferences on several distinct occasions during the history of this arthropod order. Crews and colleagues surveyed spiders and reported in 2019 that 21 taxonomic families include semiaquatic species, suggesting that the evolutionary event occurred multiple independent times. Only a swashbuckling few—not even 0.3 percent of described spider species—are seashore spiders; many more have been found near fresh water, says Nelson.

It’s not clear what would induce successful land-dwelling critters to move to watery habitats. Spiders, as a group, probably evolved about 400 million years ago from chunkier creatures that had recently left the water. These arthropods lacked the skinny waist sported by modern spiders. Presumably, the spiders that later returned to a life aquatic were strongly drawn by something to eat there, or driven by unsafe conditions on land, says Geerat Vermeij, a paleobiologist and professor emeritus at the University of California, Davis — because water would have presented major survival challenges.

“Since they depend on air so much, they are severely limited in whether they can do anything at all when they are submerged, other than just toughing it out,” says Vermeij. Newly aquatic spiders would have had to compete with predators better adapted to watery conditions, such as crustaceans, with competition particularly fierce in the oceans, Vermeij says. And if water floods a spider’s air circulation system, it will die, so adaptations were obviously needed.

Enlarge / Jürgen Trittin, member of the German Bundestag and former environment minister, stands next to an activist during an action of the environmental organization Greenpeace in front of the Brandenburg Gate in April 2023. The action is to celebrate the shutdown of the last three German nuclear power plants.

One year ago, Germany took its last three nuclear power stations offline. When it comes to energy, few events have baffled outsiders more.

In the face of climate change, calls to expedite the transition away from fossil fuels, and an energy crisis precipitated by Russia’s 2022 invasion of Ukraine, Berlin’s move to quit nuclear before carbon-intensive energy sources like coal has attracted significant criticism. (Greta Thunberg prominently labeled it “a mistake.”)

This decision can only be understood in the context of post-war socio-political developments in Germany, where anti-nuclearism predated the public climate discourse.

From a 1971 West German bestseller evocatively titled Peaceably into Catastrophe: A Documentation of Nuclear Power Plants, to huge protests of hundreds of thousands—including the largest-ever demonstration seen in the West German capital Bonn—the anti-nuclear movement attracted national attention and widespread sympathy. It became a major political force well before even the Chernobyl disaster of 1986.

Its motivations included: a distrust of technocracy; ecological, environmental, and safety fears; suspicions that nuclear energy could engender nuclear proliferation; and general opposition to concentrated power (especially after its extreme consolidation under the Nazi dictatorship).

Instead, activists championed what they regarded as safer, greener, and more accessible renewable alternatives like solar and wind, embracing their promise of greater self-sufficiency, community participation, and citizen empowerment (“energy democracy”).

This support for renewables was less about CO₂ and more aimed at resetting power relations (through decentralised, bottom-up generation rather than top-down production and distribution), protecting local ecosystems, and promoting peace in the context of the Cold War.

Germany’s Energiewende

The contrast here with Thunberg’s latter-day Fridays for Future movement and its “listen to the experts” slogan is striking. The older activist generation deliberately rejected the mainstream expertise of the time, which then regarded centralised nuclear power as the future and mass deployment of distributed renewables as a pipe dream.

This earlier movement was instrumental in creating Germany’s Green Party—today the world’s most influential—which emerged in 1980 and first entered national government from 1998 to 2005 as junior partner to the Social Democrats. This “red-green” coalition banned new reactors, announced a shutdown of existing ones by 2022, and passed a raft of legislation supporting renewable energy.

That, in turn, turbocharged the national deployment of renewables, which ballooned from 6.3 percent of gross domestic electricity consumption in 2000 to 51.8 percent in 2023.

These figures are all the more remarkable given the contributions of ordinary citizens. In 2019, they owned fully 40.4 percent (and over 50 percent in the early 2010s) of Germany’s total installed renewable power generation capacity, whether through community wind energy cooperatives, farm-based biogas installations, or household rooftop solar.

Most other countries’ more recent energy transitions have been attempts to achieve net-zero targets using whatever low-carbon technologies are available. Germany’s now-famous “Energiewende” (translated as “energy transition” or even “energy revolution”), however, has from its earlier inception sought to shift away from both carbon-intensive as well as nuclear energy to predominantly renewable alternatives.

Indeed, the very book credited with coining the term Energiewende in 1980 was, significantly, titled Energie-Wende: Growth and Prosperity Without Oil and Uranium and published by a think tank founded by anti-nuclear activists.

Consecutive German governments have, over the past two and a half decades, more or less hewed to this line. Angela Merkel’s pro-nuclear second cabinet (2009–13) was an initial exception.

That lasted until the 2011 Fukushima disaster, after which mass protests of 250,000 and a shock state election loss to the Greens forced that administration, too, to revert to the 2022 phaseout plan. Small wonder that so many politicians today are reluctant to reopen that particular Pandora’s box.

Another ongoing political headache is where to store the country’s nuclear waste, an issue Germany has never managed to solve. No community has consented to host such a facility, and those designated for this purpose have seen large-scale protests.

Instead, radioactive waste has been stored in temporary facilities close to existing reactors—no long-term solution.

President Nixon on the phone in the Oval Office

Oliver Atkins/National Archives

In 1971, President Richard Nixon’s science advisers proposed a multimillion dollar climate change research project with benefits they said were too “immense” to be quantified, since they involved “ensuring man’s survival,” according to a White House document newly obtained by the nonprofit National Security Archive and shared exclusively with Inside Climate News.

The plan would have established six global and 10 regional monitoring stations in remote locations to collect data on carbon dioxide, solar radiation, aerosols and other factors that exert influence on the atmosphere. It would have engaged five government agencies in a six-year initiative, with spending of $23 million in the project’s peak year of 1974—the equivalent of $172 million in today’s dollars. It would have used then-cutting-edge technology, some of which is only now being widely implemented in carbon monitoring more than 50 years later.

But it stands as yet another lost opportunity early on the road to the climate crisis. Researchers at the National Security Archive, based at the George Washington University, could find no documentation of what happened to the proposal, and it was never implemented.

“Who knows what would have happened if we had some kind of concerted effort, just even on the monitoring side of things?” asked Rachel Santarsiero, an analyst who directs the National Security Archive’s Climate Change Transparency Project.

It turns out that the monitoring proposal, which was authorized by the head of Nixon’s White House Office of Science and Technology, Edward E. David Jr., did get a second life in another form. After leaving the Nixon administration, David joined the oil giant Exxon, and as president of the Exxon Research and Engineering Company from 1977 to 1986, he signed off on a groundbreaking Exxon project that used one of its oil tankers to gather atmospheric and oceanic carbon dioxide samples, beginning in 1979. That research, which was first reported by Inside Climate News in 2015, confirmed fossil fuels’ role in global warming. It also showed the oil industry knew the harm of its products and is now a key piece of evidence in lawsuits by states and cities across the country seeking compensation from the oil industry for climate damages.

The National Security Archive relies on the Freedom of Information Act to obtain such historical documents, and it currently maintains one of the largest non-governmental archives of declassified government documents—many relating to military and security issues. In the past year, the Archive has launched a project specifically to compile the historical record of the US government’s reckoning with climate change. On Friday, to mark Earth Week, the group released a briefing book detailing climate change discussions in the Nixon White House, including the new document.

The fungi in our guts can make cases of Covid worse

Fungi are an indispensable part of your microbiome, keeping the body’s host of microorganisms healthy as part of a system of checks and balances. But when you’re hit by an infection, fungi can be thrown out of equilibrium with other organisms inside you, leading to a more severe infection and other symptoms of illness.

For this reason, the pandemic immediately set off alarms for Iliyan Iliev, an immunologist at Weill Cornell Medical School. “We were thinking, the first thing that’s going to happen is people will start getting fungal co-infections,” he says. With the microbiome unbalanced, fungi might start running riot inside Covidpatients, Iliev reasoned. His fears were soon realized.

In research published in Nature Immunology, he and his team discovered that in patients with severe Covid, certain strains of gut fungi—knocked off-kilter by the virus—set off a prolonged immune response that could last long after the initial infection. This response potentially led to some of the respiratory symptoms experienced by these patients. These results, Iliev says, point to the critical role of the gut microbiome in the human immune response and could lead to better disease treatments down the line.

Imbalance of the gut microbiome has long been linked to disease. Ken Cadwell, an immunologist at the Perelman School of Medicine at the University of Pennsylvania, thinks of the microbiome as a metaphorical rainforest. “It’s a nice ecosystem—but if you cut down too many trees or bring in invasive species, you could make things go out of whack,” he says.

To see how the body’s internal fungi were affected during Covid and how this triggered the immune system, Iliev and his team started by looking at patients’ blood. After collecting samples from 91 people with Covid, they measured levels of antibodies against several fungi, to figure out if the body’s immune system was reacting against these. Significantly more anti-fungal antibodies, for instance, would indicate fungal overgrowth or invasion.

Takato Kusakabe, a postdoctoral fellow in Iliev’s lab and study author, ran plate after plate of experiments—a painstaking process—to quantify these antibody levels. The team found in patients with severe Covid, several fungi commonly found in the gut had increased antibodies against them (in comparison to uninfected people). Notably, these included Candida albicans, which is a common culprit of yeast infections. When the team then ran tests on fecal samples from 10 of the hospitalized Covid patients, these confirmed that the fungi being targeted by the antibodies were present in the patients’ guts—and at seemingly at higher levels than in uninfected controls, suggesting an imbalance in their microbiome.

The GMO tooth microbe that is supposed to prevent cavities

oral hygiene —

Some experts have concerns over the safety of the genetically modified bacteria.

–

It's a tooth

About seven years ago, Aaron Silverbook and his then-girlfriend, a biologist, were perusing old scientific literature online. “A romantic evening,” joked Silverbook. That night, he came across a study from 2000 that surprised him. Scientists had genetically engineered an oral bacterium that they said could possibly prevent tooth decay: “I read it and sort of boggled at it and said, ‘Wow, this is a cavity vaccine. Why don’t we have this?’”

So, Silverbook tracked down the primary author, Jeffrey Hillman, a now-retired oral biologist formerly at the University of Florida, to see if he could pick up the torch.

In 2023, Silverbook founded Lantern Bioworks, which made a deal with Oragenics, the company Hillman co-founded and that owned the technology, for the materials. Lantern Bioworks then launched the genetically engineered bacteria under the name Lumina Probiotic. “I didn’t expect it to happen in my lifetime,” said Hillman.

As recently as last month, a website for the product included language about cavity prevention. And a previously available press kit stated that “a one-time brushing with this genetically modified bacteria could indefinitely prevent dental cavities.” By the time Lumina became available for pre-orders last week, however, that wording and the press kit had been removed. Silverbook—who does not have a background in dentistry or microbiology—told Undark that his lawyer advised the change in wording on the website, as Lantern Bioworks is bringing the product to market as a cosmetic, meaning it can’t make health claims about Lumina. Cosmetics don’t need to go through the same rigorous trials a drug would. “If anything I said sounded like a medical claim,” Silverbook told Undark in an interview earlier this year, “it wasn’t.”

The product can be applied to teeth as a one-time application either at home or by a dentist. Additional applications can “expedite inoculation,” Silverbook wrote in a follow-up email. He said the company anticipates Lumina will ship by mid-June.

Some people have already received it. Silverbook said he introduced Lumina into his own mouth in October of 2023, and that Lantern Bioworks has also provided it to about 60 people, including attendees of Vitalia, a biotechnology conference held in Honduras earlier this year. At the conference, Lumina was offered for $20,000 per treatment, though the pre-order price has been reduced to $250 before taxes and shipping fees. (Silverbook would not comment on how many people went for Lumina at the conference.)

Experts, though, have safety and ethical concerns: Despite earlier efforts by Oragenics, the treatment has never successfully moved through human clinical trials. “Without human trials, you really can’t determine whether it’s safe or efficacious,” said Jennifer Kuzma, a professor and co-director of the Genetic Engineering and Society Center at North Carolina State University. In fact, it’s possible it could do the opposite of its original intention: She noted that subtle changes in the oral microbiome might lead to more cavities or other problems.

“I read it and sort of boggled at it and said, ‘Wow, this is a cavity vaccine. Why don’t we have this?’”

There’s also no data about whether it could spread between people, which brings up questions of informed consent. If someone doesn’t want to risk taking the untested bacteria, but kisses or shares spoons with someone who got the product, would it be transmitted? No one is quite sure.

Although Lantern Bioworks is bringing Lumina to market as a cosmetic product, precisely how it should be categorized isn’t entirely obvious, Kuzma points out: “The regulatory system isn’t 100 percent clear on this.”

Password crackdown leads to more income for Netflix

Sharing is caring —

Netflix to stop reporting subscriber numbers, prioritizing viewer engagement instead.

Bloomberg

Netflix’s crackdown on password sharing helped the streaming service blow past Wall Street’s earnings forecasts, but its shares fell after it said it planned to stop regularly disclosing its subscriber numbers.

The company’s operating income surged 54 percent in the first quarter as it added 9.3 million subscribers worldwide, proving that the efforts to reduce password sharing it launched last year have had more lasting benefits than some investors expected.

However, Netflix said on Thursday that from next year it would stop revealing its total number of subscribers, a metric that has been a crucial benchmark for investors in the streaming era.

In its letter to shareholders, Netflix said it was shifting its focus to engagement—the amount of time its subscribers spend on the service—while also developing new price points and sources of revenue, including advertising.

“Each incremental member has a different business impact” with the new subscription plans, Greg Peters, co-chief executive, said in a call with investors. “And that means the historical simple math that we all did—the number of members times the monthly price—is increasingly less accurate in capturing the state of the business.”

He added that Netflix would “periodically update” on subscriber figures when it hits “major milestones.”

Paolo Pescatore, an analyst at PP Foresight, said Netflix’s decision to no longer disclose quarterly subscriptions starting in 2025 “will not go down well.”

“No matter the company’s attempt to switch focus from subscribers to financials, net [subscriber] adds is the key metric everyone wants to see,” he said.

The latest results showed there was still room for growth as a result of its password crackdown and push into advertising, Pescatore added. Netflix said memberships to its advertising-supported tier rose 65 percent from the previous quarter.

Before Thursday’s report the streaming pioneer’s shares had risen 30 percent this year, significantly outperforming the broader market. The shares fell 4.7 percent in after-hours trading following the earnings report.

Netflix executives said among their primary goals was improving the variety and quality of their entertainment, including television shows, movies, and games. It recently appointed Dan Lin as the new head of its film division.

“Even though we have made and we are making great films, we want to make them better,” said Ted Sarandos, co-chief executive. He added that he saw no need to spend more money on content.

Netflix has been pushing further into sports-related content, including a $5 billion deal to livestream World Wrestling Entertainment’s flagship Raw program in the US over the next decade.

It is also offering a livestream of a fight between Mike Tyson and Jake Paul in July, leading analysts to question whether the company plans to move further into live sport. “We’re not anti-sports, but pro-profitable growth,” Sarandos said.

Netflix reported earnings of $5.28 a share, well ahead of Wall Street forecasts of $4.51, while its number of subscribers rose 16 percent to 269 million from a year earlier.

Its revenue forecast for the current quarter of $9.49 billion was slightly below Wall Street forecasts of about $9.5 billion. But Netflix said it expected revenue to grow between 13 and 15 percent for the full year.

The company said it generated strong engagement in the first quarter from subscribers in the UK with Fool Me Once, which had 98 million views. Other standouts included the drama series Griselda with 66.4 million views and 3 Body Problem with about 40 million.

I don’t know where I’m going —

Experience may matter more than innate ability when it comes to sense of direction.

Scientists are homing in on how navigation skills develop.

Knowable Magazine (CC BY-ND)

Like many of the researchers who study how people find their way from place to place, David Uttal is a poor navigator. “When I was 13 years old, I got lost on a Boy Scout hike, and I was lost for two and a half days,” recalls the Northwestern University cognitive scientist. And he’s still bad at finding his way around.

The world is full of people like Uttal—and their opposites, the folks who always seem to know exactly where they are and how to get where they want to go. Scientists sometimes measure navigational ability by asking someone to point toward an out-of-sight location—or, more challenging, to imagine they are someplace else and point in the direction of a third location—and it’s immediately obvious that some people are better at it than others.

“People are never perfect, but they can be as accurate as single-digit degrees off, which is incredibly accurate,” says Nora Newcombe, a cognitive psychologist at Temple University who coauthored a look at how navigational ability develops in the 2022 Annual Review of Developmental Psychology. But others, when asked to indicate the target’s direction, seem to point at random. “They have literally no idea where it is.”

While it’s easy to show that people differ in navigational ability, it has proved much harder for scientists to explain why. There’s new excitement brewing in the navigation research world, though. By leveraging technologies such as virtual reality and GPS tracking, scientists have been able to watch hundreds, sometimes even millions, of people trying to find their way through complex spaces, and to measure how well they do. Though there’s still much to learn, the research suggests that to some extent, navigation skills are shaped by upbringing.

Nurturing navigation skills

The importance of a person’s environment is underscored by a recent look at the role of genetics in navigation. In 2020, Margherita Malanchini, a developmental psychologist at Queen Mary University of London, and her colleagues compared the performance of more than 2,600 identical and nonidentical twins as they navigated through a virtual environment to test whether navigational ability runs in families. It does, they found—but only modestly. Instead, the biggest contributor to people’s performance was what geneticists call the “nonshared environment”—that is, the unique experiences each person accumulates as their life unfolds. Good navigators, it appears, are mostly made, not born.

A remarkable, large-scale experiment led by Hugo Spiers, a cognitive neuroscientist at University College London, gave researchers a glimpse at how experience and other cultural factors might influence wayfinding skills. Spiers and his colleagues, in collaboration with the telecom company T-Mobile, developed a game for cellphones and tablets, Sea Hero Quest, in which players navigate by boat through a virtual environment to locate a series of checkpoints. The game app asked participants to provide basic demographic data, and nearly 4 million worldwide did so. (The app is no longer accepting new participants except by invitation of researchers.)

Through the app, the researchers were able to measure wayfinding ability by the total distance each player traveled to reach all the checkpoints. After completing some levels of the game, players also had to shoot a flare back toward their point of origin—a dead-reckoning test analogous to the pointing-to-out-of-sight-locations task. Then Spiers and his colleagues could compare players’ performance to the demographic data.

Several cultural factors were associated with wayfinding skills, they found. People from Nordic countries tended to be slightly better navigators, perhaps because the sport of orienteering, which combines cross-country running and navigation, is popular in those countries. Country folk did better, on average, than people from cities. And among city-dwellers, those from cities with more chaotic street networks such as those in the older parts of European cities did better than those from cities like Chicago, where the streets form a regular grid, perhaps because residents of grid cities don’t need to build such complex mental maps.

Energy rising —

Geothermal has moved beyond being confined to areas with volcanic activity.

Glistening in the dry expanses of the Nevada desert is an unusual kind of power plant that harnesses energy not from the sun or wind, but from the Earth itself.

Known as Project Red, it pumps water thousands of feet into the ground, down where rocks are hot enough to roast a turkey. Around the clock, the plant sucks the heated water back up to power generators. Since last November, this carbon-free, Earth-borne power has been flowing onto a local grid in Nevada.

Geothermal energy, though it’s continuously radiating from Earth’s super-hot core, has long been a relatively niche source of electricity, largely limited to volcanic regions like Iceland where hot springs bubble from the ground. But geothermal enthusiasts have dreamed of sourcing Earth power in places without such specific geological conditions—like Project Red’s Nevada site, developed by energy startup Fervo Energy.

Such next-generation geothermal systems have been in the works for decades, but they’ve proved expensive and technologically difficult, and have sometimes even triggered earthquakes. Some experts hope that newer efforts like Project Red may now, finally, signal a turning point, by leveraging techniques that were honed in oil and gas extraction to improve reliability and cost-efficiency.

The advances have garnered hopes that with enough time and money, geothermal power—which currently generates less than 1 percent of the world’s electricity, and 0.4 percent of electricity in the United States—could become a mainstream energy source. Some posit that geothermal could be a valuable tool in transitioning the energy system off of fossil fuels, because it can provide a continuous backup to intermittent energy sources like solar and wind. “It’s been, to me, the most promising energy source for a long time,” says energy engineer Roland Horne of Stanford University. “But now that we’re moving towards a carbon-free grid, geothermal is very important.”

A rocky start

Geothermal energy works best with two things: heat, plus rock that is permeable enough to carry water. In places where molten rock sizzles close to the surface, water will seep through porous volcanic rock, warm up and bubble upward as hot water, steam, or both.

If the water or steam is hot enough—ideally at least around 300 degrees Fahrenheit—it can be extracted from the ground and used to power generators for electricity. In Kenya, nearly 50 percent of electricity generated comes from geothermal. Iceland gets 25 percent of its electricity from this source, while New Zealand gets about 18 percent and the state of California, 6 percent.

Some natural geothermal resources are still untapped, such as in the western United States, says geologist Ann Robertson-Tait, president of GeothermEx, a geothermal energy consulting division at the oilfield services company SLB. But by and large, we’re running out of natural, high-quality geothermal resources, pushing experts to consider ways of extracting geothermal energy from areas where the energy is much harder to access. “There’s so much heat in the Earth,” Robertson-Tait says. But, she adds, “much of it is locked inside rock that isn’t permeable.”

The Lardarello plant in the Tuscany region of Italy was the first geothermal power plant in the world. It was completed in 1913.

Tapping that heat requires deep drilling and creating cracks in these non-volcanic, dense rocks to allow water to flow through them. Since 1970, engineers have been developing “enhanced geothermal systems” (EGS) that do just that, applying methods similar to the hydraulic fracturing—or fracking—used to suck oil and gas out of deep rocks. Water is pumped at high pressure into wells, up to several miles deep, to blast cracks into the rocks. The cracked rock and water create an underground radiator where water heats before rising to the surface through a second well. Dozens of such EGS installations have been built in the United States, Europe, Australia, and Japan—most of them experimental and government-funded—with mixed success.

Famously, one EGS plant in South Korea was abruptly shuttered in 2017 after having probably caused a 5.5-magnitude earthquake; fracking of any kind can add pressure to nearby tectonic faults. Other issues were technological—some plants didn’t create enough fractures for good heat exchange, or fractures traveled in the wrong direction and failed to connect the two wells.

Some efforts, however, turned into viable power plants, including several German and French systems built between 1987 and 2012 in the Rhine Valley. There, engineers made use of existing fractures in the rock.

But overall, there just hasn’t been enough interest to develop EGS into a more reliable and lucrative technology, says geophysicist Dimitra Teza of the energy research institute Fraunhofer IEG in Karlsruhe, Germany, who helped develop some of the Rhine Valley EGS systems. “It has been quite tough for the industry.”

Geothermal electricity has long been limited to volcanic regions where underground heat is easily accessible. But new kinds of power plants are making it possible to derive geothermal heat elsewhere in the world.

Taiwan Semiconductor Manufacturing Company’s decision to bring its latest technology to America is a big step forward for US President Joe Biden’s quest for security in the vital tech supply chain—but still leaves Washington short of being able to completely produce the most complex chips in the US.

The world’s biggest chipmaker by sales must also pull off an intricate balancing act as it steps up its US presence, satisfying customers such as Nvidia without damaging its highly profitable business model, which has underpinned the development of the global semiconductor industry for more than 30 years.

TSMC’s planned $65 billion of investments in Arizona are part of a construction race in the US that involves other global chipmakers such as Samsung and Intel, which are also taking big subsidies from Washington.

But producing chips for purposes such as AI is still likely to involve plants in Asia, a reflection of the complexity involved in packaging various types of chip together to boost their performance and efficiency.

“It’s really not that simple to onshore everything. Having the logic [chip] foundry in the US and then a bit of the packaging there is not enough,” said Myron Xie, an analyst at boutique consultancy SemiAnalysis.

TSMC—which makes chips under contract at hugely complex and expensive fabrication plants, or fabs—plans to start manufacturing 2-nanometer chips in the US in 2028. This is an upgrade from the company’s previous plans. At that time 2 nm technology is expected to be the latest in mass production worldwide, whereas previously the company had intended each new US fab to start operating with process technology one generation behind Taiwan.

TSMC has also committed to offer a third plant using 2 nm or even newer technology by 2030.

Washington is paying a hefty price for the upgrade, with US$6.6 billion in grants and up to $5 billion in loans for TSMC. The money comes from the 2022 Chips and Science Act, which aims to onshore advanced chipmaking for the US. Commerce secretary Gina Raimondo has said the US will be on track to make about 20 percent of the world’s most advanced chips by the end of the decade.

But while Washington’s money offers some incentive, TSMC’s most important motive for stepping up its commitment to the US was to bring its own US strategy in line with the needs of Nvidia and other vendors of the AI chips that have become the most potent driver of global semiconductor demand.

While TSMC will kick off 2 nm volume production in Taiwan next year, its original plans would have offered less powerful 3 nm chips only from 2028 in the US, putting it years behind the AI chip cycle, analysts said.

A box of beetles

Caroline Chaboo’s eyes light up when she talks about tortoise beetles. Like gems, they exist in myriad bright colors: shiny blue, red, orange, leaf green and transparent flecked with gold. They’re members of a group of 40,000 species of leaf beetles, the Chrysomelidae, one of the most species-rich branches of the vast beetle order, Coleoptera. “You have your weevils, longhorns, and leaf beetles,” she says. “That’s really the trio that dominates beetle diversity.”

An entomologist at the University of Nebraska, Lincoln, Chaboo has long wondered why the kingdom of life is so skewed toward beetles: The tough-bodied creatures make up about a quarter of all animal species. Many biologists have wondered the same thing, for a long time. “Darwin was a beetle collector,” Chaboo notes.

Despite their kaleidoscopic variety, most beetles share the same three-part body plan. The insects’ ability to fold their flight wings, origami-like, under protective forewings called elytra allows beetles to squeeze into rocky crevices and burrow inside trees. Beetles’ knack for thriving in a large range of microhabitats could also help explain their abundance of species, scientists say.

Beetles’ knack for thriving in a large range of microhabitats could also help explain their abundance of species, scientists say.

Of the roughly 1 million named insect species on Earth, about 400,000 are beetles. And that’s just the beetles described so far. Scientists typically describe thousands of new species each year. So—why so many beetle species? “We don’t know the precise answer,” says Chaboo. But clues are emerging.

One hypothesis is that there are lots of them because they’ve been around so long. “Beetles are 350 million years old,” says evolutionary biologist and entomologist Duane McKenna of the University of Memphis in Tennessee. That’s a great deal of time in which existing species can speciate, or split into new, distinct genetic lineages. By way of comparison, modern humans have existed for only about 300,000 years.

Yet just because a group of animals is old doesn’t necessarily mean it will have more species. Some very old groups have very few species. Coelacanth fish, for example, have been swimming in the ocean for approximately 360 million years, reaching a maximum of around 90 species and then declining to the two species known to be living today. Similarly, the lizard-like reptile the tuatara is the only living member of a once globally diverse ancient order of reptiles that originated about 250 million years ago.

Another possible explanation for why beetles are so rich in species is that, in addition to being old, they have unusual staying power. “They have survived at least two mass extinctions,” says Cristian Beza-Beza, a University of Minnesota postdoctoral fellow. Indeed, a 2015 study using fossil beetles to explore extinctions as far back as the Permian 284 million years ago concluded that lack of extinction may be at least as important as diversification for explaining beetle species abundance. In past eras, at least, beetles have demonstrated a striking ability to shift their ranges in response to climate change, and this may explain their extinction resilience, the authors hypothesize.

Claims of TikTok whistleblower may not add up

The United States government is currently poised to outlaw TikTok. Little of the evidence that convinced Congress the app may be a national security threat has been shared publicly, in some cases because it remains classified. But one former TikTok employee turned whistleblower, who claims to have driven key news reporting and congressional concerns about the app, has now come forward.

Zen Goziker worked at TikTok as a risk manager, a role that involved protecting the company from external security and reputational threats. In a wrongful termination lawsuit filed against TikTok’s parent company ByteDance in January, he alleges he was fired in February 2022 for refusing “to sign off” on Project Texas, a $1.5 billion program that TikTok designed to assuage US government security concerns by storing American data on servers managed by Oracle.

Goziker worked at TikTok for only six months. He didn’t hold a senior position inside the company. His lawsuit, and a second one he filed in March against several US government agencies, makes a number of improbable claims. He asserts that he was put under 24-hour surveillance by TikTok and the FBI while working remotely in Mexico. He claims that US attorney general Merrick Garland, director of national intelligence Avril Haines, and other top officials “wickedly instigated” his firing. And he states that the FBI helped the CIA share his private information with foreign governments. The suits do not appear to include evidence for any of these claims.

“This lawsuit is full of outrageous claims that lack merit and comes from an individual who significantly exaggerates his role with a company he worked at for merely six months,” TikTok spokesperson Michael Hughes said in a statement.

Yet court records and emails viewed by WIRED suggest that when Goziker raised the alarm about his ex-employer’s links to China, he found a ready audience. After he was fired, Goziker says he began meeting with elected officials, law enforcement agencies, and journalists to allege that, court documents say, he had discovered proof that TikTok’s software could send US data to Toutiao, a ByteDance app in China. That claim directly conflicted with TikTok executives’ assertions that the two companies operated separately.

Goziker says in court filings that what he saw made it necessary to reassess Project Texas. He also alleges that his account of the internal connection to China formed the basis of an influential Washington Post story published in March last year, which said the concerns came from “a former risk manager at TikTok.”

TikTok officials were quoted in that article as saying the allegations were “unfounded,” and that the employee had discovered “nothing more than a naming convention and technical relic.” The Washington Post said it does not comment on sourcing.

“I am free, I am honest, and I am doing this only because I am an American and because USA desperately need help and I cannot keep this truth away from PUBLIC,” Goziker said in an email to WIRED.

His March lawsuit alleging US officials conspired with TikTok to have him fired was filed against Garland, Haines, Secretary of Homeland Security Alejandro Mayorkas, and the agencies they work for.

“Goziker’s main point is that the executives in the American company TikTok Inc. and certain executives from the American federal government have colluded to organize a fraud scheme,” Sean Jiang, Goziker’s lawyer in the case against the US government, told WIRED in an email. The lawsuits do not appear to contain evidence of such a scheme. The Department of Homeland Security and Office of the Director of National Intelligence did not respond to requests for comment. The Department of Justice declined to comment.

Jiang calls the House’s recent passage of a bill that could force ByteDance to sell off TikTok “problematic,” because it “blames ByteDance instead of TikTok Inc for the wrongdoings of the American executives.” He says Goziker would prefer to see TikTok subjected to audits and a new corporate structure.
