WELLINGTON, New Zealand (AP) — From Sunday, workers at the main United States base in Antarctica will no longer be able to walk into a bar and order a beer, after the federal agency that oversees the research program decided to stop serving alcohol.

McMurdo Station will not be going entirely dry, the National Science Foundation confirmed. Researchers and support staff will still be able to buy a weekly ration of alcohol from the station store. But the policy shift could prove significant because the bars have been central to social life in the isolated environment.

The changes come as concerns grow that sexual misconduct has been allowed to flourish at McMurdo. An investigation by The Associated Press last month uncovered a pattern of women who said their claims of harassment or assault were minimized by their employers, often leading to them or others being put in further danger.

In some of the cases outlined by the AP, alcohol played a role. But the NSF told the AP the changes involving alcohol were related to morale and welfare at the base, and were not aimed at preventing sexual harassment or assault.

Under the new rules taking effect Sunday, workers will be able to order only alcohol-free drinks at McMurdo's two main bars, Southern Exposure and Gallagher’s. They will still be able to bring their own alcohol to drink at the bars. A third venue which also served alcohol, the Coffee House, will become entirely alcohol-free but will now stay open for workers to visit any time of the day or night.

The current alcohol ration allows Antarctic workers to buy up to the equivalent of 18 beers each week, or three bottles of wine, or a 750 milliliter (25 ounce) bottle of spirits.

The NSF said it's also instituting several new measures during the current southern hemisphere spring and upcoming summer that are aimed at preventing sexual harassment and assault at the base, where typically around 70% of workers are men. These include enhanced training, a new survey to collect data and monitor trends, and visits to the ice from experts.

Karen Marrongelle, the NSF's chief operating officer, said it was committed to ensuring a safe environment wherever science or education was conducted.

“We will not rest until we are confident that every member of the Antarctic community feels safe and supported,” she said in a statement.

The NSF published a report in 2022 in which 59% of women said they’d experienced harassment or assault while on the ice, and 72% of women said such behavior was a problem in Antarctica. Last year, the NSF created an office to deal with such complaints, provided a confidential victim’s advocate, and established a 24-hour helpline.

The AP investigation found a pattern of problems at McMurdo. One woman who reported a colleague had groped her was made to work alongside him again. Another woman who told her employer she was sexually assaulted was fired two months later. Another woman said bosses at the base downgraded her allegations from rape to harassment.

After the AP published its investigation, the NSF sent a message to U.S. Antarctic Program workers.

“We know that it can be difficult to hear these accounts. It is for us,” the NSF wrote in the email, which was obtained by the AP. “These are not experiences we want anyone to have within the USAP (or anywhere else in the world).”

The email outlined the new anti-harassment measures the NSF planned to implement and offered resources for support.

Jennifer Sorensen, who told the AP she was raped at McMurdo in 2015, said the NSF had tried unsuccessfully before to blame alcohol for the high rates of sexual misconduct at the base.

“They know full well that all the rationing or denial of alcohol sales being forced on us isn't going to do a damn thing,” she said.

If the NSF and lead contractor Leidos were serious about stopping sexual misconduct, they should start believing survivors and ensure they aren't retaliated against, she said. They should also stop rehiring perpetrators, she added.

“Alcohol can obviously blur the lines of consent, there's that issue at play, but overwhelmingly, sexual assault has occurred even when neither party has been consuming alcohol, as was the case with me,” Sorensen said. “So it's definitely not going to eliminate the problem."

Sorensen said that if the NSF wants to reduce drinking, it should provide alternative diversions, such as the bowling alley, ceramic studio and greenhouse which used to be features at McMurdo but have disappeared due to budget cutbacks.

Britt Barquist, who said she was groped at McMurdo in 2017, said in an email it was positive that the NSF was making an effort to improve the culture at the base. But she remained concerned that incidents were still being swept under the rug when it put a contracting company's primary objectives at risk.

“For example, my incident took place during work hours, at a job site, no alcohol involved, and was corroborated and reported through official channels,” Barquist wrote. “I was later told by my company’s HR that I would have to work with the perpetrator again because his job was mission-critical and there was no one else to fill his role. None of these new policies implemented by the NSF would prevent that from happening again.”

The NSF and Leidos have declined to answer questions about Barquist's case, or others highlighted in the AP's report.

Under another new initiative to improve morale, the NSF said it will be expanding internet access through the satellite network Starlink, allowing workers to stay better connected to people back home. Starlink is run by SpaceX, the company founded by Elon Musk.

The NSF first foreshadowed impending changes to its alcohol policies in a blog post early last month, and said it first told workers about the new anti-harassment measures in mid-August.

The AP sent the NSF a detailed list of questions about its investigation in early June and has continued to correspond since, including asking for any planned changes to address sexual harassment and assault. The NSF never listed any planned changes to alcohol policies.

“Because these changes are related to morale and welfare and not sexual assault/harassment prevention, we did not mention this program initiative in our previous response,” the NSF said in a statement.

American Climate Corps: Biden's new green jobs initiative delivers more promises than details

When President Joe Biden created the American Climate Corps by executive order on Sept. 20, 2023, it marked a step toward keeping a pledge he made nearly three years earlier: to create a new workforce training and service program to deal with global warming.

The White House promises that the corps “will ensure more young people have access to the skills-based training necessary for good-paying careers in the clean energy and climate resilience economy.” By helping Americans get entry-level green jobs, such as solar panel installation and home insulation, it will equip thousands more young Americans to tackle the complex challenges posed by climate change.

As a scholar who researches and teaches about the history of U.S. volunteer service programs, I believe that the American Climate Corps will not provide anything radically new. Rather, it will largely offer the same experiences and work opportunities as an array of programs that already exist. But the Biden administration’s promise of connecting national service experience to long-term careers offers one important change to this model that I believe will make a difference to those who participate.

New Deal echoes

The inspiration for the American Climate Corps comes from President Franklin D. Roosevelt’s Civilian Conservation Corps. That New Deal program put unemployed – and mainly white – young men to work on public lands across the country to counter the devastating unemployment of the Great Depression.

Known as the CCC, it was a massive undertaking. Approximately 3 million men passed through its ranks over nine years. Those who served built much of the infrastructure of the country’s state and national parks, planted over 2 billion trees, fought forest fires and responded to natural disasters like floods.

The Biden administration aims to make its new corps far more inclusive in terms of gender, race and ethnic diversity. Rather than alleviating a short-term employment crisis, like its Depression-era predecessor, the American Climate Corps will emphasize launching careers.

So far it’s unclear how big this program will be. The White House has declined to specify a budget after repeatedly failing to persuade Congress to designate any funding for similar multibillion-dollar green jobs efforts because of Republican opposition.

Reportedly, the scaled-down American Climate Corps that Biden has bypassed Congress to establish could be funded through money appropriated to other parts of the government, such as the U.S. Agriculture Department, AmeriCorps and the National Oceanic and Atmospheric Administration.

The American Climate Corps, according to the details available, will mobilize far fewer participants than the CCC. The White House plans call for 20,000 people once it’s up and running, only 4% of the Civilian Conservation Corps’ peak enrollment of 500,000 men in 1935

Network of similar programs already in place

This new service program is hardly the first to draw on the CCC’s example.

There are about 150 similar conservation service programs in the U.S., all connected through the National Association of Service and Conservation Corps. Known as the Corps Network, this patchwork includes 150 programs that give young adults and veterans opportunities to engage in service work on public lands and in rural and urban communities.

One of the oldest programs in what’s known as the Corps Network is the Student Conservation Association, founded in 1957. It puts thousands of high school and college-aged students to work on hiking trail improvement, tree planting and the restoration of natural acreage and waterways. Smaller programs like MobilizeGreen and New York City’s Green City Force focus on building a more inclusive green economy and training people for leadership skills or in tasks like building resilient urban food systems.

Many of these programs already get government funding through AmeriCorps, the federal agency for national service and volunteerism.

AmeriCorps also runs its own similar programs. The National Civilian Community Corpsestablished in 1993, deploys teams of young adults to projects that encompass energy conservation, infrastructure improvement, disaster recovery and response, and urban and rural development. Its website promises that “if you are 18-26, you can gain experience while supporting climate change mitigation.”

Operating since 1985, this amalgam of service programs already engages 20,000 young adults and veterans every year – the same number the Biden administration aims to mobilize. It’s unclear how the American Climate Corps might augment, replace or complement these programs. For instance, the corps’ focus on job training tied to solar, wind and other forms of renewable energy is relatively new – although some states have their own climate corps. Its emphasis on conserving land and water overlaps with the work existing state programs already do.

Scant objective evidence

There are different ways to assess whether service programs make a difference.

Many of them survey their participants, who regularly say they enjoyed the experience. Participants also cite a sense of personal growth, greater familiarity with environmental concerns and stronger leadership skills. One of the few studies conducted also found that people who took part in the conservation corps were more likely to pursue related careers.

These programs try to measure the impact of their work every year using metrics like hours served, miles of trails restored and acres of wetlands or forestry rehabilitated. But the data is largely self-reported and has never been rigorously or objectively collected and explored.

That means it’s hard to say whether funding these programs amount to an effective policy.

Better pay? Great opportunities?

Participants in the conservation corps programs that preceded Biden’s executive order get what amounts to small stipends and perhaps room and board. The low pay, which ranges from about US$16,000-$30,000 a year, can mean that they’re not an option for many recent college grads who might otherwise be interested.

Full-time AmeriCorps volunteers are also eligible to apply for grants to pay for their education or to make student loan payments on top of their earnings. These awards provide $6,895 in the 2023 fiscal year.

American Climate Corps backers argue it should pay a living wage as a form of “climate justice.”

It’s unclear whether the American Climate Corps will do that.

That’s why it’s important that the Biden administration is promising pathways to a high-paid career. It has outlined future cooperation between Americorps, the National Oceanic and Atmosphere Administration and the departments of Labor, Interior, Agriculture and Energy to help build links between American Climate Corps service and federal employment.

Answers to operational questions TBD

On top of the lack of clarity about its cost and funding and what participants will earn, it’s not clear to what extent the American Climate Corps will operate independently, or if it will support similar programs in the Corps Network.

For example, CaliforniaMichiganMaineWashington and Colorado already have their own climate corps. Five more states – Arizona, Utah, Minnesota, North Carolina and Maryland – unveiled their own when Biden signed the executive order for a national one.

Perhaps most importantly, it’s yet to be determined whether the American Climate Corps’ service work will differ from those state initiatives and similar programs. If not, this could simply be the rebranding of conservation programs as climate action.

‘Absolutely false’: Justin Trudeau denies flying to G20 in plane full of cocaine
THAT WAS BOLSONARO OF BRAZIL

Namita Singh
Thu, 28 September 2023

Canadian prime minister Justin Trudeau’s office strongly denied the claim that his plane was “full of cocaine” when he came to India for the G20 meet this month.

“This (is) absolutely false and a troubling example of how disinformation can make its way into media reporting,” his office said in a statement on Wednesday as it dismissed the unsubstantiated claim floated by a retired Indian diplomat during a TV discussion, according to the Toronto Star.

The bizarre claim, which has been widely reported in the Indian media, comes amid a fierce diplomatic spat between the two countries. Canada and India have both ejected one of each other’s senior diplomats after Mr Trudeau said there were “credible allegations” of Indian state involvement in the death of a Sikh leader in Canada.

Former Indian ambassador to Sudan Deepak Vohra said on Monday there were “credible rumours” that “sniffer dogs found cocaine on his plane” and that Mr Trudeau “didn’t come out of his room for two days”.

“He didn’t go to the president’s dinner. People say he was in a drug-induced stupor,” Mr Vohra claimed while appearing on Zee News as a panelist on a show hosted by anchor Deepak Chaurasia.

The show began as the anchor attempted to unpack “how the brain of the Canadian prime minister worked”.

“Does he have a brain? He is a tiny infant,” responded Mr Vohra, adding that when his wife spotted Mr Trudeau at Delhi airport, he looked “troubled”.

“...Can’t say what’s going on in his head but I understand his behaviour shows he was freaked out,” he said. His claims were not questioned by the anchor.

"He has become lonely. He is now trying to show that he is a Canadian Rambo and nothing can go wrong in his presence. India has done the right thing by suspending visa services in Canada," he said.

The comments came during one of the worst spells for diplomatic relations between India and Canada in decades following the killing of Sikh separatist leader Hardeep Singh Nijjar.

The crisis between New Delhi and Ottawa unfolded last week after prime minister Justin Trudeau accused the Indian state of involvement in the killing of the Canadian national.

Nijjar was murdered in Vancouver on 18 June by two masked men, who fired an estimated 30 to 50 shots at him.

Canadian officials say they have human and signals intelligence backing up their claims regarding the killing, including communications involving Indian officials in Canada, CBC reported.

"I can assure you that the decision to share these allegations on the floor of the House of Commons … was not done lightly," Mr Trudeau told parliament last week. "It was done with the utmost seriousness."

The allegations have sparked a bitter row between the two countries.

Ottawa expelled a senior diplomat working for Indian intelligence, while India – which labelled Nijjar a “terrorist” in 2020 – angrily rejected the allegation as "absurd", expelled the chief of Canadian intelligence in India, issued travel warnings, stopped issuing visas for Canadians and ordered Canada to downsize its diplomatic presence in India.

India steel secretary says closely watching Canada situation

By Neha Arora

NEW DELHI (Reuters) - India's steel ministry is monitoring the trade situation between New Delhi and Canada after a diplomatic row erupted when Canadian Prime Minister Justin Trudeau said last week he suspected India of involvement in an assassination on Canadian soil.

"It is an evolving situation and we are closely watching," steel secretary Nagendra Nath Sinha told Reuters.

Earlier in the day, Sinha had told reporters that exports to Canada were marginal and have not been affected by the diplomatic row.

Last week, Reuters reported that India's JSW Steel Ltd was slowing down the process of buying a stake in the steelmaking coal unit of Canada's Teck Resources, in the first sign that the spat was affecting trade ties.

Trudeau said Canada was "actively pursuing credible allegations" linking Indian government agents to the murder of a Sikh separatist leader in British Columbia in June. India's foreign ministry called the allegations "absurd."

Chechen leader Kadyrov meets Putin after storm over prisoner beating

Reuters
Updated Thu, September 28, 2023


Russian President Putin and Chechen leader Kadyrov meet in Moscow

(Reuters) -Chechen leader Ramzan Kadyrov said he discussed his region's contribution to Russia's war effort in Ukraine at talks with President Vladimir Putin on Thursday that came at a sensitive moment in relations between the two sides.

Kadyrov enjoys wide leeway from Putin to run Chechnya ruthlessly as his personal fiefdom, but he angered even pro-Kremlin hardliners this week by praising his 15-year-old son for beating up an ethnic Russian prisoner in Chechen custody.

Kadyrov posted on Telegram that he and Putin had talked about a range of topics including the role of Chechen fighters in Ukraine. He added teasingly that "other issues" were raised, and promised "more on this later."

It was not clear if he was referring to the beating incident last month in which his son Adam kicked and punched a prisoner called Nikita Zhuravel who is accused of burning the Koran.

Kadyrov posted a video of the attack on Monday and said he was proud of his son for defending his Muslim religion.

The alleged Koran-burning did not take place in Chechnya but Russian investigators said they transferred Zhuravel to Chechen custody because Muslims there saw themselves as victims of the incident.

The beating opened up Putin to accusations that he had handed over an ethnic Russian "to be devoured by the Chechens", former Kremlin speechwriter Abbas Gallyamov, now a harsh Putin critic, said this week. Even pro-Kremlin war commentators described the episode as an outrage.

Rumours swirled this month that Kadyrov, 46, was seriously ill in hospital, but he laughed and flexed his biceps when asked about his health by a Russian TV reporter.

Kadyrov has mused publicly about handing over power at some point and has raised the profile of his three teenaged sons, the eldest of whom was photographed with Putin in the Kremlin in March.

Ensuring stability in Chechnya is vital to Moscow, which has fought two brutal and costly wars since the collapse of the Soviet Union to prevent it from breaking away.

Mysterious ‘fairy circles’ identified at hundreds of sites worldwide, new study says

Thu, September 28, 2023

Round discs of barren dirt known as “fairy circles” look like rows of polka dots that can spread for miles over the ground. The phenomenon’s mysterious origins have intrigued scientists for decades — and they may be far more widespread than once thought.

Fairy circles were previously spotted only in the arid lands of Southern Africa’s Namib Desert and the outback of Western Australia. But a new study has used artificial intelligence to identify vegetation patterns resembling fairy circles in hundreds of new locations across 15 countries on three continents. This could help scientists understand fairy circles and their formation on a global scale.

For the new survey, published Monday in the journal Proceedings of the National Academy of Sciences, the researchers analyzed datasets containing high-resolution satellite images of drylands, or arid ecosystems with scant rainfall, from around the world. The search for patterns resembling fairy circles used a neural network — a type of AI that processes information in a manner similar to that of a brain.

“The use of artificial intelligence based models on satellite imagery is the first time it has been done on a large scale to detect fairy-circle like patterns,” said lead study author Dr. Emilio Guirado, a data scientist with the Multidisciplinary Institute for Environmental Studies at the University of Alicante in Spain, in an email.
Hundreds of potential fairy circle sites

First, the study authors trained the neural network to recognize fairy circles by inputting more than 15,000 satellite images taken over Namibia and Australia. Half of the images showed fairy circles, and half did not. The scientists then fed their AI a dataset with satellite views of nearly 575,000 plots of land around the world, each measuring about 2.5 acres (1 hectare). The neural network scanned vegetation in those images and identified repeating circular patterns that resembled patterns of known fairy circles, evaluating the circles’ sizes and shapes as well as their locations, pattern densities and distribution.

Output of this analysis then required a human review, Guirado said. “We had to manually discard some artificial and natural structures that were not fairy circles based on photo-interpretation and the context of the area,” he explained.

The results showed 263 dryland locations where there were circular patterns similar to fairy circles in Namibia and Australia. These arid spots were distributed across Africa (the Sahel, Western Sahara and the Horn of Africa) and were also clustered in Madagascar and Midwestern Asia, as well as central and Southwest Australia.
Circle pattern recognition

Fairy circles aren’t the only natural phenomenon that can produce round, repeated bare spots in a landscape. One factor that sets fairy circles apart from other types of vegetation gaps is a strongly ordered pattern between the circles, said Dr. Stephan Getzin, a researcher in the department of ecosystem modeling at the University of Göttingen in Germany.

Getzin and colleagues published a November 2021 paper defining fairy circles and what made them unique, emphasizing details of the overall pattern structure, he told CNN in an email. And according to Getzin, who was not involved in the latest study, the newfound patterns fall short.

“Fairy circles are defined by the fact that they have, in principle, the ability to form a ‘spatially periodic’ pattern,” which is “significantly more ordered” than other patterns — and none of the patterns in the survey clear that high bar, Getzin said.

But in fact, there is no universally accepted definition of fairy circles, Guirado said. He and his coauthors identified potential fairy circles — gauging the size and shape of individual circles, as well as the patterns they formed collectively — by referencing guidelines established across multiple published studies. The metrics of those spatial patterns, in fairy circles old and new, “are virtually the same,” he said.

Of the new locations that were identified, some passed muster with Dr. Fiona Walsh, who as part of an international team has investigated fairy circles in the Australian outback. “Pattern distribution in Australia appears to be congruent with some of what we previously reported,” said Walsh, an ethnoecologist at the University of Western Australia. Walsh was not involved in the new survey.
Fairy circles’ mysterious origins

The study authors also compiled environmental data where circles were spotted, collecting evidence that might hint at what causes them to form. The researchers determined that fairy circle-like patterns were most likely to occur in very dry, sandy soils that were high-alkaline and low in nitrogen. The scientists also found the fairy circle-like patterns helped stabilize ecosystems, increasing an area’s resistance to disturbances such as floods or extreme drought.

But the question “What shapes fairy circles?” is complex, and factors that create fairy circles may differ from site to site, the study authors reported. Getzin previously wrote that certain climate conditions, along with self-organization in plants, generated fairy circles in Namibia, and while insects such as termites take advantage of the dry patches, their activities don’t directly produce the patterns, he said in the email.

Walsh, however, said that Australia’s fairy circles are inextricably linked to termite activity. Their team’s research, conducted in close collaboration with indigenous peoples, determined that in Western Australia and in the Northern Territory, termites are intrinsic to the functioning of fairy circles, called “linyji” in the Manyjilyjarra language, and “mingkirri” in the Warlpiri language, she told CNN in an email.

“Aboriginal people illustrated these patterns at least since the 1980s and said they knew of them for generations, probably millennia earlier,” Walsh said.

“In Australia, termites do not simply ‘play a role’,” she added. “They are the primary mechanism and interpretations need to be centred on termite-grass-soil-water dynamics.”

Many questions about fairy circles have yet to be answered, and the authors of the new study are optimistic that their global atlas will open a new chapter in the study of these peculiar barren spots.

“We hope that the information we publish in the paper can provide scientists around the world with new areas of study that will solve new puzzles in the formation of fairy-circle patterns,” Guirado said.

Mysterious ‘fairy circles’ found dotting Africa and Australia now found in more parts of world

Vishwam Sankaran
Wed, September 27, 2023


Strange circular patches called “fairy circles” dotting the arid terrains of Namibia and Australia have puzzled scientists for decades and have now been mapped across 250 locations that span 15 countries.

Until now, the enigmatic circular patterns of bare soil surrounded by plants generating rings of vegetation had only been described in Namibia and Australia.

Multiple theories have been proposed over the past five decades to explain their formation, but the global dimension of the phenomena has remained elusive, said researchers, including those from Universidad de Alicante (UA) in Spain.

The new study, published on Tuesday in the journal PNAS, used artificial intelligence to classify satellite images, obtaining 263 sites where patterns similar to the fairy circles have been described to date, including from Namibia and Western Australia.

The analysis found these patches in places like the Sahel, Western Sahara, the Horn of Africa, Madagascar, southwest Asia and central Australia, suggesting fairy circles are “far more common than previously thought”.

“Analyzing their effects on the functioning of ecosystems and discovering the environmental factors that determine their distribution is essential to better understand the causes of the formation of these vegetation patterns and their ecological importance,” study co-author Emilio Guirado from UA said.

Scientists found that the combination of certain soil and climate characteristics, such as low nitrogen content and an average rainfall of less than 200 mm/year, are associated with the presence of fairy circles.

“This study has taken into account multiple variables hitherto not considered, such as albedo or the state of the aquifers,” said Jaime Martínez-Valderrama, another author of the study.

“This is a particularly relevant factor, since the massive use of groundwater in arid areas around the world, including deserts, could disturb these formations,” Dr Martínez-Valderrama said.

The new findings, according to researchers, also open the door to research on whether these patterns on the soil can be indicators of ecosystem degradation with the climate crisis.

With the new study, scientists have also made available a global atlas of fairy circles and a database that could be useful in determining whether these vegetation patterns are more resilient to climate change and other disturbances.

Mysterious 'fairy circles' may appear on three different continents

Laura Baisas
Wed, September 27, 2023 



The natural circles that pop up on the soil in the planet’s arid regions are an enduring scientific debate and mystery. These “fairy circles” are circular patterns of bare soil surrounded by plants and vegetation. Until very recently, the unique phenomena have only been described in the vast Namib desert and the Australian outback. While their origins and distribution are hotly debated, a study with satellite imagery published on September 25 in the journal Proceedings of the National Academy of Sciences (PNAS) indicates that fairy circles may be more common than once realized. They are potentially found in 15 countries across three continents and in 263 different sites.

These soil shapes occur in arid areas of the Earth, where nutrients and water are generally scarce. Their signature circular pattern and hexagonal shape is believed to be the best way that the plants have found to survive in that landscape. Ecologist Ken Tinsly observed the circles in Namibia in 1971, and the story goes that he borrowed the name fairy circles from a naturally occurring ring of mushrooms that are generally found in Europe.

By 2017, Australian researchers found the debated western desert fairy circles, and proposed that the mechanisms of biological self-organization and pattern formation proposed by mathematician Alan Turing were behind them. In the same year, Aboriginal knowledge linked those fairy circles to a species of termites. This “termite theory” of fairy circle origin continues to be a focus of research—a team from the University of Hamburg in Germany published a study seeming to confirm that termites are behind these circles in July.

In this new study, a team of researchers from Spain used artificial intelligence-based models to look at the fairy circles from Australia and Namibia and directed it to look for similar patterns. The AI scoured the images for months and expanded the areas where these fairy circles could exist. These locations include the circles in Namibia, Western Australia, the western Sahara Desert, the Sahel region that separates the African savanna from the Sahara Desert, the Horn of Africa to the East, the island of Madagascar, southwestern Asia, and Central Australia.

The team then crossed-checked the results of the AI system with a different AI program trained to study the environments and ecology of arid areas to find out what factors govern the appearance of these circular patterns.

"Our study provides evidence that fairy-circle[s] are far more common than previously thought, which has allowed us, for the first time, to globally understand the factors affecting their distribution," study co-author and Institute of Natural Resources and Agrobiology of Seville soil ecologist Manuel Delgado Baquerizo said in a statement.

According to the team, these circles generally appear in arid regions where the soil is mainly sandy, there is water scarcity, annual rainfall is between 4 to 12 inches, and low nutrient continent in the soil.

"Analyzing their effects on the functioning of ecosystems and discovering the environmental factors that determine their distribution is essential to better understand the causes of the formation of these vegetation patterns and their ecological importance," study co-author and University of Alicante data scientist Emilio Guirado said in a statement.

More research is needed to determine the role of insects like termites in fairy circle formation, but Guirado told El País that “their global importance is low,” and that they may play an important role in local cases like those in Namibia, “but there are other factors that are even more important.”

The images are now included in a global atlas of fairy circles and a database that could help determine if these patterns demonstrate resilience to climate change.

"We hope that the unpublished data will be useful for those interested in comparing the dynamic behavior of these patterns with others present in arid areas around the world,” said Guirado.

Found: Human Genetic Populations Once Thought Lost

A research team was able to locate human populations in an African desert believed to have disappeared more than 50 years ago.

DNA studies helped show the genetic differences between neighboring groups of populations and how they changed over time.

Researching understudied regions of high ethnolinguistic diversity opens new avenues of knowledge.


Probing the deep genetic web of the African continent has revealed a deeply divergent ancestry among mixed populations in the Angolan Namib Desert. And that web certainly had some secrets to reveal, according to a recent study published in Science Advances.

“We were able to locate groups which were thought to have disappeared more than 50 years ago,” Jorge Rocha, one of the authors of the study, said in a news release.

The African continent has the highest level of genetic diversity in the world. But that diversity isn’t always clearly on display. It can be hard to tell one genetic population from another if the groups have become relatively intermixed, and if the outward signs of a population—like, say, their native languages—disappear, it can appear that the population itself is gone.

Often, clues to modern genetic populations are found by mining information from ancient DNA. But due to the natural decay of these samples, they paint an incomplete picture. In order to get the clearest possible understanding of the true genetic diversity of the Angolan Namib Desert, the team went in search of modern DNA samples that could supplement our ancient bank of genetic information.

In their search, the team located the Kwepe group, which once spoke the click language Kwadi. When evidence of the Kwadi language disappeared, researchers believed that the Kwepe were gone as well. But there they were, in the modern day. The team even found two individuals who could still speak Kwadi.

The team also contacted Bantu-speaking groups and other marginalized populations associated with foraging traditions whose original languages were previously believed lost.

“Previous studies revealed that foragers from the Kalahari Desert descend from an ancestral population who was the first to split from all other extant humans,” Mark Stoneking, a professor at the Max Plank Institute for Evolutionary Anthropology, said in a news release. “Our results consistently place the newly identified ancestry within the same ancestral lineage but suggest that the Namib-related ancestry diverged from all other southern African ancestries, followed by a split of northern and southern Kalahari ancestries.”

The study of these groups helps show that both genetic and linguistic differences can be associated with lifestyle variances. For example, the more different two populations lifestyles were—say, one was a pastoral group and the other was a hunter-gatherer group—the more their genetic makeup and linguistic expression seemed to differ. “A lot of our efforts were placed in understanding how much of this local variation and global eccentricity was caused by genetic drift,” Sandra Oliverira of the University of Bern said in a news release, “a random process that disproportionately affects small populations and by admixtures from vanished populations.”

The study authors said that studying ancient DNA can reveal the genetic structure of Africa before the expansion of the Bantu-speaking agriculturalists, but that understanding the potential impacts on the “genetic makeup of present-day African groups” from other potentially extinct societies “remain[s] elusive.”

By diving into the desert, the team located small-scale groups with ties to varying traditions, such as foraging and speaking Kwadi. They were then able to dissect ancestry into smaller groups and reconstruct the histories of emerging migration patterns. The team used this information to show a “deeply divergent ancestry” in groups from the Angolan Namib region.

This kind of detailed population analysis helps to reconstruct the histories and migration of southern African people—for example, the team saw how Khoe speakers mixed with the Kalahari people earlier than the Bantu speakers arrived—and demonstrates the value in modern DNA research.

“The unique genetic heritage of the Namib peoples shows how modern DNA research targeting understudied regions of high ethnolinguistic diversity,” the authors wrote, “can complement ancient DNA studies in probing the deep genetic structure of the African continent.”
