Guinea-Bissau’s presidential poll has already failed the credibility test

Source: The Conversation – Africa (2) – By Jonathan Powell, Visiting assistant professor, University of Kentucky

Guinea-Bissau heads into its November elections against the backdrop of a deepening crisis of electoral legitimacy across Africa. In recent months, a string of elections has reinforced the perception that incumbency, not competition, remains the standard.

In Cameroon, 92-year-old Paul Biya claimed an eighth consecutive term after officially winning 53.7% of a vote widely denounced as fraudulent and met with protests.

In Tanzania, President Samia Suluhu Hassan was declared the victor with an implausible 98% of ballots cast in her favour following a poll marred by numerous irregularities and followed by protests and a crackdown unprecedented in the country’s history.

And in Côte d’Ivoire, President Alassane Ouattara comfortably secured a fourth term with nearly 90% of the vote, extending his hold on power despite the constitution’s two-term limit.

Across the continent, including west Africa, these outcomes have fuelled public cynicism and highlighted a worrying erosion of democratic norms, as leaders manipulate constitutions, neutralise opponents, and hollow out institutions meant to safeguard accountability.

It is within this climate of regional disillusionment that Bissau-Guineans will head to the polls on 23 November.

The west African country’s upcoming election once offered the potential to demonstrate a growing electoral resilience, a deepening of institutional strength that would help the country break from past legacies of instability. Instead, the process has been repeatedly undermined by President Umar Sissoco Embaló.

As social scientists who have written extensively on political instability in Africa, we believe that such dynamics all but guarantee another entry to the roster of failed elections across the region.

At stake is more than Guinea-Bissau’s democratic credibility. Its unravelling speaks to a wider regional crisis in which incumbents erode legitimacy not by abolishing elections, but by emptying them of real competition.

A legacy of instability

In contrast to long-tenured leaders like Biya or Ouattara, or enduring parties such as Tanzania’s Chama Cha Mapinduzi (CCM), Guinea-Bissau’s voters navigate an electoral system defined by unpredictability and instability, especially during election season.

The country’s modern electoral turbulence can be traced back decades. João Bernardo “Nino” Vieira returned to power in 2005 for a second stint, nearly a quarter-century after first seizing control via a 1980 coup.

His rule was marred by conflict, including an 11-month civil war triggered by a rebellion from former army chief of staff Ansumane Mané. Vieira’s long first tenure ended in a second coup in May 1999, and his second term was cut short in 2009 when he was murdered by members of the armed forces.

Malam Bacai Sanhá emerged as Vieira’s elected successor but passed away in January 2012, leaving Raimundo Pereira as interim president. Within months, Pereira would be removed in yet another military coup.

The 2012 upheaval halted a runoff election between Carlos Domingos Gomes Júnior and Kumba Ialá.

The 2014 election brought José Mário Vaz to the presidency, defeating a candidate with close ties to the military. When Vaz completed his term in 2020, he became Guinea-Bissau’s first president to finish a constitutionally defined tenure.

Undermining the process

Questions arose even before Vaz’s exit. After Umar Sissoco Embaló was declared the winner over Pereira in the 29 December runoff, Pereira challenged the results. Ignoring the ongoing legal process, Embaló arranged an inauguration ceremony for himself in February 2020.

The African Party for Independence of Guinea and Cape Verde (PAIGC) accused Embaló of orchestrating a coup and appointed Cipriano Cassamá as an interim president.

Embaló then ordered the deployment of the military to state institutions, including the National Assembly. Cassamá stepped down on his second day, citing death threats.

The supreme court ultimately declined to rule on the dispute after its chief judge fled the country, also citing death threats. The crisis was effectively resolved by the Economic Community of West African States’ (Ecowas) recognition of the Embaló government. Uncertainty, however, would continue to plague the new government.

In May 2022, three months after an attempted coup, Embaló dissolved and suspended parliament.

The main opposition party, the PAIGC, formally regained parliamentary control in the June 2023 elections, setting the stage for continued confrontation between the presidency and the legislative majority. Embaló again pursued the dissolution of parliament in December 2023.

Although Embaló’s term officially expired in February 2025, the supreme court later ruled he could remain in office until 4 September.

Even after that date, Embaló remained in office. These manoeuvres have heightened concerns about the erosion of constitutional norms.

Concerns over the broader electoral environment have also come to the fore. Legislative elections initially scheduled for late November 2024 were indefinitely postponed due to alleged funding and logistical challenges. Earlier, Embaló had declared he would not seek reelection, only to reverse course in March 2025.

A mediation team deployed by the Economic Community of West African States, tasked with helping the sides agree to and honour an election timeline, abruptly withdrew following threats of expulsion from the Embaló government.

More recently, the PAIGC’s chosen presidential candidate, Domingos Simões Pereira, was barred from contesting the November election after the supreme court rejected his candidacy over the late submission of documents.

For the first time in Guinea-Bissau’s history, the country’s oldest and most influential party will be excluded from the presidential race.

The country has fallen in the Electoral Democracy Index, provided by the Varieties of Democracy (V-Dem). As shown in the graph below, the decline even outpaces the drop witnessed after military coups in 2003, 2012, and the assassination of Vieira in 2009.

The V-Dem data end in 2024, and thus do not yet capture the 2025 election cycle.

Performative elections, entrenched power

What is unfolding in Guinea-Bissau is not an isolated crisis. It is part of a wider regional pattern in which leaders recognise that elections can be held, even celebrated, while hollowing out nearly everything that once made them meaningful. Critically, the recent coups in the region have been linked, in part, to popular frustration with flawed electoral processes.

Embaló has not entrenched himself with the personal longevity of Cameroon’s Biya or the institutional dominance of Tanzania’s CCM, but the mechanisms he has used to tilt the field look strikingly similar.

The removal of viable opponents, the manipulation of constitutional timelines, the coercive use of the security sector, and the corrosion of judicial independence all signal a shift away from accountability.

Guinea-Bissau was for the first time in decades poised to demonstrate that democratic resilience could be strengthened. Instead, the 2025 election cycle risks becoming another example of how fragile gains can be reversed with impunity.

Violence is a normal part of life for many young children: study traces the mental health impacts

Source: The Conversation – Africa (2) – By Kirsten A Donald, Professor of Paediatric Neurology and Development, University of Cape Town

Children in many countries are growing up surrounded by violence. It may happen at home, in their neighbourhoods, or both. Some children are directly harmed, while others witness violence between caregivers or in their communities. Either way, the impact can be profound.

Evidence shows that the relationship between violence exposure and poor mental health can be seen even before a child is old enough to go to school. Researchers are learning that early adversities can have lifelong consequences.

We are researchers in paediatric neuroscience and psychology who set out to understand how early experiences of violence are shaping young children’s cognitive and emotional health in low- and middle-income countries. Here we discuss our findings from a review of studies from 20 countries and new data from a large cohort of children in South Africa.

We found that violence exposure is extremely common in all the countries we looked at and that its effects on mental health are already visible in childhood.

The response will require action at all levels – families, communities, health systems and governments.

Gaps in the research

Early childhood (birth to 8 years) is a critical period for emotional, social and cognitive development. Mental health or cognitive difficulties that begin in the preschool years can shape children’s relationships, learning and wellbeing well into adolescence and adulthood. Yet, little is known about how violence affects children in the early years in low – and middle-income countries, where violence rates can be high. Most research focuses on school-age children or adolescents, missing the window when prevention may be most effective, in early childhood.

We aimed to fill that gap by collating existing knowledge and generating new evidence from South African children. This formed the basis of co-author Lucinda’s PhD thesis.

First, we reviewed 17 published studies from 20 low- and middle-income countries, examining how violence exposure affects children’s cognitive functioning. Second, we used data from almost 1,000 children in the Drakenstein Child Health Study, a long-running birth cohort in a peri-urban community outside Cape Town. We examined these children’s exposure to different types of violence by age four-and-a-half and assessed their mental health at age five.

What we found

Sadly, our findings revealed that violence exposure is extremely common.

The review found that over 70% of the studies drawing from 27,643 children from 20 countries, aged up to 11, across four continents, reported poor cognitive outcomes associated with experiencing maltreatment, intimate partner violence and war.

In our South African cohort, by age 4.5 years, 83% of children were exposed to some form of violence. This included witnessing community violence (74%), witnessing domestic violence (32%), and being direct victims in the community (13%) or at home (31%). Nearly half (45%) experienced more than one type of violence.

Why South Africa’s children are vulnerable to violence and injuries


In many countries, early exposure to violence is not exceptional. It is a normal part of growing up for many children.

Regarding how violence affects mental health in early childhood, the South African data showed that preschool children exposed to more violence displayed more internalising symptoms, such as anxiety, fear, or sadness, and externalising symptoms, such as aggression, hyperactivity, and rule-breaking. Experiencing violence at home and witnessing violence in the community were particularly linked with these difficulties.

One of the clearest findings was that multiple exposures compounded the risk. Children who experienced both domestic and community violence were at particularly high risk of mental health difficulties, especially experiencing externalising symptoms.

Public health challenge

These results highlight a major public health challenge, which starts early. These patterns appear before school entry, suggesting that violence exposure can alter developmental pathways well before formal education begins.

Since the risks from mental health difficulties linked to violence were visible by age five, waiting to intervene until school-age misses a crucial opportunity.

Impacts to wellbeing in early childhood can cause some children to internalise distress and others to act out, but both can disrupt learning, relationships and future mental health.

It is a stark reality that in some communities, most children are affected by violence. Individual therapy alone cannot fix a problem this widespread. It is a population-level issue. Broader community and policy responses are needed, such as the INSPIRE strategies developed by the World Health Organization.

Where to from here

The reality is grim and calls for quick and informed action at all levels: families, communities, health systems, and governments. A successful response will include:

  1. Early identification: Health and community services should routinely ask about violence exposure, including witnessing violence, during early childhood visits.

  2. Support for families: Interventions that reduce domestic violence, strengthen parenting skills, and provide mental health and social support can protect both children and adults.

  3. Addressing community violence: Safer neighbourhoods, violence prevention efforts and policing reforms should be implemented and also clearly linked with child mental health strategies in policy wording.

  4. Policy that prioritises early childhood: Governments and NGOs should embed early violence prevention and child mental health promotion into national health and education strategies.

  5. Monitoring and revising strategies: Improving data collection and data quality will help track progress and inform improvements to further interventions.

Violence against children carries a huge cost for Africa: governments need to act urgently


Violence exposure in early childhood is widespread in low- and middle-income countries and has clear impacts on young children’s mental health. These effects emerge early, grow with multiple exposures, and require early intervention at every level. Protection and support are essential to build healthier and safer communities for the future.

There is hope as some organisations in South Africa are working to prevent violence against women and children, and intervening for those affected.

US drops tariffs on $2b of NZ exports

Minister for Trade and Investment Todd McClay

Tariffs have been removed from more than $2 billion worth of New Zealand’s exports to the United States, Trade Minister Todd McClay says.

US president Donald Trump on Friday (US time) signed an executive order cancelling tariffs on a wide range of food imports, including New Zealand beef and kiwifruit.

The new exemptions marked a sharp reversal, as Trump had long insisted his import duties were not fueling inflation for Americans.

But McClay said climbing prices and declining supply may have prompted the president to change tack.

“If you’re not getting as much beef coming in because of the tariff rate, there are shortages and prices will go up.”

The US buys New Zealand beef because it is high quality and the country does not produce enough of its own, said McClay.

The minister expected beef exports would return to the volume from before the tariffs were introduced.

He said about a quarter of New Zealand’s trade to the US had tariffs removed, but he wanted more products stripped of the taxes.

“I and the prime minister have consistently made the case that we don’t think it’s justified, that our trade is complementary and well-balanced.

“But in the case of the change, particularly for kiwifruit worth about $250 million a year and meat or beef exports about $2b a year for New Zealand, this is welcome news and we would hope there could be more over time.”

Meat Industry Association chief executive Nathan Guy said it was surprising but exciting news for farmers and processors.

“We’ve always thought these tariffs could indeed be inflationary for US consumers,” he said.

“This is a very important market for us, indeed it is our number one, despite the 15 percent tariffs, because the demand has been so strong in the US.”

Guy said it seemed beef would revert back to a 1 percent tariff which was “business as usual” – but lamb was still subject to 15 percent.

“We’ll keep raising that issue, we’ll work with the New Zealand Government and indeed ministers and officials and even the prime minister.”

He was pleased to see prime minister Christopher Luxon recently met with Donald Trump, and believed New Zealand’s relationship with the US was “in good heart”.

“This is a positive step forward.”

The change would restore a level playing field with key competitors like Australia, which had avoided the extra tariffs, Guy said.

From text-based chatbots that mimic loved ones to voice avatars that let you “speak” with the deceased, artificial intelligence (AI) is increasingly being used to preserve the voices and stories of the dead.

In our research, recently published in Memory, Mind & Media, we explored what happens when remembering the dead is left to an algorithm.

We even tried talking to digital versions of ourselves to find out.

Why the chemtrail conspiracy theory lingers and grows – and why Tucker Carlson is talking about it

Everyone has looked up at the clouds and seen faces, animals, objects. Human brains are hardwired for this kind of whimsy. But some people – perhaps a surprising number – look to the sky and see government plots and wicked deeds written there. Conspiracy theorists say that contrails – long streaks of condensation left by aircraft – are actually chemtrails, clouds of chemical or biological agents dumped on the unsuspecting public for nefarious purposes. Different motives are ascribed, from weather control to mass poisoning.

The chemtrails theory has circulated since 1996, when conspiracy theorists misinterpreted a U.S. Air Force research paper about weather modification, a valid topic of research. Social media and conservative news outlets have since magnified the conspiracy theory. One recent study notes that X, formerly Twitter, is a particularly active node of this “broad online community of conspiracy.”

I’m a communications researcher who studies conspiracy theories. The thoroughly debunked chemtrails theory provides a textbook example of how conspiracy theories work.

Boosted into the stratosphere

Conservative pundit Tucker Carlson, whose podcast averages over a million viewers per episode, recently interviewed Dane Wigington, a longtime opponent of what he calls “geoengineering.” While the interview has been extensively discredited and mocked in other media coverage, it is only one example of the spike in chemtrail belief.

Although chemtrail belief spans the political spectrum, it is particularly evident in Republican circles. U.S. Secretary of Health and Human Services Robert F. Kennedy Jr. has professed his support for the theory. U.S. Rep. Marjorie Taylor Greene of Georgia has written legislation to ban chemical weather control, and many state legislatures have done the same.

Online influencers with millions of followers have promoted what was once a fringe theory to a large audience. It finds a ready audience among climate change deniers and anti-deep state agitators who fear government mind control.

Heads I win, tails you lose

Although research on weather modification is real, the overwhelming majority of qualified experts deny that the chemtrail theory has any solid basis in fact. For example, geoengineering researcher David Keith’s lab posted a blunt statement on its website. A wealth of other resources exist online, and many of their conclusions are posted at contrailscience.com.

But even without a deep dive into the science, the chemtrail theory has glaring logical problems. Two of them are falsifiability and parsimony.

The philosopher Karl Popper explains that unless your conjecture can be proved false, it lies outside the realm of science.

According to psychologist Rob Brotherton, conspiracy theories have a classic “heads I win, tails you lose” structure. Conspiracy theorists say that chemtrails are part of a nefarious government plot, but its existence has been covered up by the same villains. If there was any evidence that weather modification was actually happening, that would support the theory, but any evidence denying chemtrails also supports the theory – specifically, the part that alleges a cover-up.

People who subscribe to the conspiracy theory consider anyone who confirms it to be a brave whistleblower and anyone who denies it to be foolish, evil or paid off. Therefore, no amount of information could even hypothetically disprove it for true believers. This denial makes the theory nonfalsifiable, meaning it’s impossible to disprove. By contrast, good theories are not false, but they must also be constructed in such a way that if they were false, evidence could show that.

Nonfalsifiable theories are inherently suspect because they exist in a closed loop of self-confirmation. In practice, theories are not usually declared “false” based on a single test but are taken more or less seriously based on the preponderance of good evidence and scientific consensus. This approach is important because conspiracy theories and disinformation often claim to falsify mainstream theories, or at least exploit a poor understanding of what certainty means in scientific methods.

Like most conspiracy theories, the chemtrail story tends not to meet the criteria of parsimony, also known as Occam’s razor, which suggests that the more suppositions a theory requires to be true, the less likely it actually is. While not perfect, this concept can be an important way to think about probability when it comes to conspiracy theories. Is it more likely that the government is covering up a massive weather program, mind-control program or both that involve thousands or millions of silent, complicit agents, from the local weather reporter to the Joint Chiefs of Staff, or that we’re seeing ice crystals from plane engines?

Of course, calling something a “conspiracy theory” does not automatically invalidate it. After all, real conspiracies do exist. But it’s important to remember scientist and science communicator Carl Sagan’s adage that “extraordinary claims require extraordinary evidence.” In the case of chemtrails, the evidence just isn’t there.

Scientists explain how humans are susceptible to believing conspiracy theories.

Psychology of conspiracy theory belief

If the evidence against it is so powerful and the logic is so weak, why do people believe the chemtrail conspiracy theory? As I have argued in my new book, “Post-Weird: Fragmentation, Community, and the Decline of the Mainstream,” conspiracy theorists create bonds with each other through shared practices of interpreting the world, seeing every detail and scrap of evidence as unshakable signs of a larger, hidden meaning.

Uncertainty, ambiguity and chaos can be overwhelming. Conspiracy theories are symptoms, ad hoc attempts to deal with the anxiety caused by feelings of powerlessness in a chaotic and complicated world where awful things like tornadoes, hurricanes and wildfires can happen seemingly at random for reasons that even well-informed people struggle to understand. When people feel overwhelmed and helpless, they create fantasies that give an illusion of mastery and control.

Although there are liberal chemtrail believers, aversion to uncertainty might explain why the theory has become so popular with Carlson’s audience: Researchers have long argued that authoritarian, right-wing beliefs have a similar underlying structure.

On some level, chemtrail theorists would rather be targets of an evil conspiracy than face the limits of their knowledge and power, even though conspiracy beliefs are not completely satisfying. Sigmund Freud described a fort-da (“gone-here”) game played by his grandson where he threw away a toy and dragged it back on a string, something Freud interpreted as a simulation of control when the child had none. Conspiracy theories may serve a similar purpose, allowing their believers to feel that the world isn’t really random and that they, the ones who see through the charade, really have some control over it. The grander the conspiracy, the more brilliant and heroic the conspiracy theorists must be.

Conspiracies are dramatic and exciting, with clear lines of good and evil, whereas real life is boring and sometimes scary. The chemtrail theory is ultimately prideful. It’s a way for theorists to feel powerful and smart when they face things beyond their comprehension and control. Conspiracy theories come and go, but responding to them in the long term means finding better ways to embrace uncertainty, ambiguity and our own limits alongside a new embrace of the tools we do have: logic, evidence and even humility.

Blue Origin’s New Glenn rocket landed its booster on a barge at sea – an achievement that will broaden the commercial spaceflight market

Blue Origin’s New Glenn rocket successfully made its way to orbit for the second time on Nov. 13, 2025. Although the second launch is never as flashy as the first, this mission is still significant in several ways.

For one, it launched a pair of NASA spacecraft named ESCAPADE, which are headed to Mars orbit to study that planet’s magnetic environment and atmosphere. The twin spacecraft will first travel to a Lagrange point, a place where the gravity between Earth, the Moon and the Sun balances. The ESCAPADE spacecraft will remain there until Mars is in better alignment to travel to.

And two, importantly for Blue Origin, New Glenn’s first stage booster successfully returned to Earth and landed on a barge at sea. This landing allows the booster to be reused, substantially reducing the cost to get to space.

Blue Origin launched its New Glenn rocket and landed the booster on a barge at sea on Nov. 13, 2025.

As a space policy expert, I see this launch as a positive development for the commercial space industry. Even though SpaceX has pioneered this form of launch and reuse, New Glenn’s capabilities are just as important.

New Glenn in context

Although Blue Origin would seem to be following in SpaceX’s footsteps with New Glenn, there are significant differences between the two companies and their rockets.

For most launches today, the rocket consists of several parts. The first stage helps propel the rocket and its spacecraft toward space and then drops away when its fuel is used up. A second stage then takes over, propelling the payload all the way to orbit.

While both New Glenn and Falcon Heavy, SpaceX’s most powerful rocket currently available, are partially reusable, New Glenn is taller, more powerful and can carry a greater amount of payload to orbit.

Blue Origin plans to use New Glenn for a variety of missions for customers such as NASA, Amazon and others. These will include missions to Earth’s orbit and eventually to the Moon to support Blue Origin’s own lunar and space exploration goals, as well as NASA’s.

NASA’s Artemis program, which endeavors to return humans to the Moon, is where New Glenn may become important. In the past several months, several space policy leaders, as well as NASA officials, have expressed concern that Artemis is progressing too slowly. If Artemis stagnates, China may have the opportunity to leap ahead and beat NASA and its partners to the lunar south pole.

These concerns stem from problems with two rockets that could potentially bring Americans back to the Moon: the space launch system and SpaceX’s Starship. NASA’s space launch system, which will launch astronauts on its Orion crew vehicle, has been criticized as too complex and costly. SpaceX’s Starship is important because NASA plans to use it to land humans on the Moon during the Artemis III mission. But its development has been much slower than anticipated.

In response, Blue Origin has detailed some of its lunar exploration plans. They will begin with the launch of its uncrewed lunar lander, Blue Moon, early next year. The company is also developing a crewed version of Blue Moon that it will use on the Artemis V mission, the planned third lunar landing of humans.

Blue Origin officials have said they are in discussions with NASA over how they might help accelerate the Artemis program.

New Glenn’s significance

New Glenn’s booster landing makes this most recent launch quite significant for the company. While it took SpaceX several tries to land its first booster, Blue Origin has achieved this feat on only the second try. Landing the boosters – and, more importantly, reusing them – has been key to reducing the cost to get to space for SpaceX, as well as others such as Rocket Lab.

That two commercial space companies now have orbital rockets that can be partially reused shows that SpaceX’s success was no fluke.

With this accomplishment, Blue Origin has been able to build on its previous experience and success with its suborbital rocket, New Shepard. Launching from Blue Origin facilities in Texas since 2015, New Shepard has taken people and cargo to the edge of space, before returning to its launch site under its own power.

New Glenn is also significant for the larger commercial space industry and U.S. space capabilities. It represents real competition for SpaceX, especially its Starship rocket. It also provides more launch options for NASA, the U.S. government and other commercial customers, reducing reliance on SpaceX or any other launch company.

In the meantime, Blue Origin is looking to build on the success of New Glenn’s launch and its booster landing. New Glenn will next launch Blue Origin’s Blue Moon uncrewed lander in early 2026.

This second successful New Glenn launch will also contribute to the rocket’s certification for national security space launches. This accomplishment will allow the company to compete for contracts to launch sensitive reconnaissance and defense satellites for the U.S. government.

Blue Origin will also need to increase its number of launches and reduce the time between them to compete with SpaceX. SpaceX is on pace for between 165 and 170 launches in 2025 alone. While Blue Origin may not be able to achieve that remarkable cadence, to truly build on New Glenn’s success it will need to show it can scale up its launch operations.

Different ‘breeds’ of dog started emerging more than 10,000 years ago

Source: Radio New Zealand

Dogs — in their many shapes and sizes — are considered one of the most diverse species of animals on the planet.

Most of these breeds are thought to have emerged during the 19th-century Victorian era.

But a new paper, published this week in the journal Science, suggests that about half of the vast diversity in dogs we see today was evident by the middle of the Stone Age.

Your dog can read your mind – sort of

A team of researchers across Europe analysed hundreds of dog and wolf skulls spanning the past 50,000 years to track how the animals first emerged.

This evolution might be tied to the animal’s domestication, says Carly Ameen, the study’s co-lead researcher and a bioarchaeologist at the University of Exeter.

“We found that dogs were already remarkably diverse in their skull shapes and sizes more than 11,000 years ago,” Dr Ameen said.

“This means much of the physical diversity we associate with modern breeds actually has very deep roots, emerging soon after domestication.”

Evolving from wolves to dogs

While dogs have been human companions for thousands of years, untangling exactly when our furry friends went from wolves to domestic animals is difficult to do.

Timelines using different scientific techniques to determine when this evolutionary transition occurred don’t match up.

Genetic evidence shows dogs diverged from wolves about 11,000 years ago, but much older fossils suggest the first dogs roamed around as early as 35,000 years ago.

To examine their evolution in a different way, the researchers took 643 skulls of ancient wolves and dogs, and made 3D scans of them to analyse how their shapes changed over time and place.

These subtle shape changes provide clearer evidence of when wolves became dogs, but also of how dogs diversified into the modern era, the researchers said.

Using these 3D models, they found a distinctive dog-like skull shape emerged around 11,000 years ago, which lines up with genetic evidence.

But the models also showed a surprising amount of diversity among ancient dogs across Europe.

“While we don’t see some of the most extreme forms of skull shape that we see today — like pugs or bull terriers — the variation we see by the [middle of the Stone Age] is already half the total amount of variation we see in modern breeds,” Dr Ameen said.

“But for those features to develop, domestication must have started much earlier.”

While the research suggests a large amount of diversity existed as early as the Stone Age, many of the dogs we keep as pets today emerged during the 19th century, when intensive breeding produced speciality animals for fights and shows.

Early humans moved with dogs

Melanie Fillios, an anthropological archaeologist at the University of New England, said the study’s findings — including that almost half the variation in dogs occurred long before the Victorian era — suggested humans weren’t the sole cause of breed diversity.

“There’s all this variability 11,000 years ago, but we’re not sure why,” Professor Fillios, who was not involved in the paper, said.

“Humans have had a hand in it … but there’s also part of the story that may not have been humans.”

According to Dr Ameen, the environment may also have shaped the earliest varieties of dogs.

“Some [dogs] lived with mobile hunter-gatherers in cold northern environments, others with groups in temperate forests or early farming communities,” she said.

“Each context brought different demands — for hunting, guarding, or companionship — and that variation likely shaped dogs’ morphology and evolution from the very beginning.”

A second study, also published today in Science, pushes this idea further, suggesting that dogs likely moved with humans as they began migrating around the globe about 11,000 years ago after the last glacial period ended.

The study’s authors noted that dogs were occasionally traded among populations, which might mean they were important for culture and potentially even trading between groups.

“There’s all of these factors coming together around this time period… You’re getting this giant melting pot,” Professor Fillios said.

Dingoes don’t fit the mould

While Professor Fillios said the study brought together “a lot of information for the first time”, it left plenty of questions still unanswered.

“It’s another piece of the puzzle… but it doesn’t solve the question of dog domestication or human intervention in that process.”

She also noted that studies like this struggled to explain the emergence of species such as dingoes, which occur on an evolutionary “side branch”.

It’s unknown how long dingoes have been in Australia, but estimates suggest somewhere between 3,500 and 8,000 years ago.

“It would be a really nice story if all this [dog] diversity … corresponds with genetic evidence, and people moving around the world,” she said.

But when it comes to dingoes, this timeline didn’t work, she said.

“There is no relationship between dingoes and these other branches that came to be the domestic village dogs and Asian and European dogs that we see today.”

For both Dr Ameen and Professor Fillios, more research is needed to understand how dogs first became our companions.

“Dogs were the first species we ever domesticated, and they’ve been evolving with us ever since,” Dr Ameen said.

“While dogs are among the most studied domestic species… a lot remains to be discovered.”

How I found an unexpected connection to science in the works of Iris Murdoch – by a molecular biophysicist

Source: The Conversation – UK – By Rivka Isaacson, Professor of Molecular Biophysics, King’s College London

When I first began appropriating the plots of British-Irish novelist Iris Murdoch’s novels to explain scientific concepts, I never stopped to think about whether Murdoch herself would have approved of such an endeavour.

As a professor of molecular biophysics, I find that in both scientific research and all aspects of life, there can be great advantage in thinking differently. I’ve recently given some sessions on this at the Physics of Life summer school, and the fun, ideas and feedback were beyond my wildest dreams – especially as I’d been encouraged to conceal this side of myself as a young scientist.

Back in the 1990s, I did my PhD on protein folding – a conundrum underpinning all biology which has challenged scientists for decades. I wrote about it for The Conversation when a breakthrough won the Nobel prize in chemistry in 2024.

At its heart is a question of competing energies: entropic forces, which motivate a protein and its surrounding medium to move as freely as possible, versus enthalpic, in which positive charges gravitate towards negative charges and things with oily properties congregate. Protein folding is driven by finding the best balance in a three-dimensional shape to satisfy as many of these forces as possible.

An early book by the Booker-winning author A.S. Byatt, Degrees of Freedom, examines the power structures and layers of control that drive Murdoch novels. It’s a comparable scenario to protein folding: the compromise between many clashing forces.

When Degrees of Freedom first came out in 1965, Murdoch had published nine novels. The book was reissued in 1994 with additional material, when only Murdoch’s final novel, Jackson’s Dilemma – written when Alzheimer’s disease was just beginning to invade her beautiful mind – had yet to emerge.

Reading Murdoch’s 1975 novel A Word Child in 2003, I was struck by the helix-shaped nature of the plot, with London Underground’s Circle Line platform pubs at Sloane Square and Liverpool Street acting as points of vulnerability. I immediately turned to Byatt’s book to see whether her analysis matched my own.

In finding there was no chapter on A Word Child, I trawled the internet and discovered the Iris Murdoch Society, which one could join for the princely sum of £5. Signing up at that time required emailing Anne Rowe at Kingston University, and I couldn’t resist explaining my thoughts on A Word Child and the molecular mechanisms underpinning Alzheimer’s disease. She invited me to submit an abstract to a conference – and from then on, I was hooked.

So far, I’ve used ten out of Murdoch’s 26 novels to illustrate topics as broad as alcoholism and its effect on the liver, sex hormone signalling, evolution, molecular crowding and electron microscopy. While I’m not in any immediate danger of running out of Murdoch material, the recent publication of Poems from an Attic, a collection assembled from material found in her Oxford home many years after her death, adds a glorious new angle to my exploits.

While Murdoch is obsessed with nature – wild swimming, the changing seasons, flora, fauna and the meditative effects of being outdoors – she often speculates in her poems as to why things are as they are, which is an undeniably scientific way of thinking. There are examples of this in many of the poems, whatever their topic.

The word science occurs three times in the new volume – the first in the poem To B, who brought me two candles as a present (B was Murdoch’s lover, Brigid Brophy):

What you require of me no science gives –

To make these fires constant but not consumed.

What blazes every moment when it lives

Has eaten its own substance as it bloomed.

Yet though they burn not all the evening through,

While they are burning each to each is true.

This provides a satisfying analogy to justify sustaining Murdoch’s simultaneous passions. It invokes the same fuel-based resignation as American poet Edna St Vincent Millay’s First Fig:

My candle burns at both ends;

It will not last the night;

But ah, my foes, and oh, my friends

It gives a lovely light!

The other two mentions of science in the new collection appear in You by Telephone – in which Murdoch muses over the changes, both positive and negative, that the invention of the phone had on the practicalities of relationships:

For I cannot close with kisses the lips that may speak me daggers,

Nor give you a gentle answer just by taking your hand.

The poem also includes this delightful digression:

In spite of the case of Odysseus, who might have got home much sooner

If at the start he could have dialled Ithaca one.

But he might have offended Hermes, that rival tele-communer,

And science would have precluded a lot of Homer’s fun.

I am relieved Murdoch didn’t have to grapple with smart phones, social media and today’s attention spans. Years ago, I scoured her archive for thoughts on science, which were mostly touched upon in correspondence, and her entertaining annotations of The Question Concerning Technology and Other Essays by Martin Heidegger, and The Tao of Physics by Fritjof Capra.

Murdoch was certainly interested in science, albeit with a healthy dose of scepticism, while being alarmed at its pace of development. I like to fantasise that I could have talked her down.

Is there a strong economic case for dropping the two-child benefits cap? This is what the evidence tells us

Source: The Conversation – UK – By Will Cook, Reader in Policy Evaluation, Manchester Metropolitan University

As she carefully prepares the UK’s reaction to her second budget the chancellor, Rachel Reeves, has now hinted that she may be ready to scrap the two-child benefits cap.

This controversial policy prevents parents from claiming child tax credit or universal credit for more than two children (this is different to child benefit payments which are not limited by family size). According to the government’s own figures, the cap affects the households of 1.7 million children, and ditching it would cost upwards of £3.6 billion a year.

Introduced in 2017 as part of measures intended to cut public expenditure on welfare, the policy was designed to ensure that households on means-tested benefits “face the same financial choices about having children as those supporting themselves solely through work”.

However, when it was brought in, the then Conservative government’s impact assessment offered limited detail on the expected costs and benefits. A more comprehensive economic analysis of scrapping the policy would need to consider both the direct fiscal implications and the broader social and economic effects.

The direct fiscal cost is perhaps the most straightforward part of the calculation. Scrapping the cap would require the government to resume payments for families with more than two children, and the £3.6 billion annual cost is considerable at a time when the UK treasury doesn’t have a lot of money to spend.

So what about the potential economic benefits? These fall into two broad areas.

The first concerns the direct impact on children. For example, there is good evidence that additional household income during childhood improves future educational attainment and health. Increasing the money available to poorer households could therefore bring long-term social benefits.

However, the evidence to date on the specific effect of the two-child limit is limited. The Institute for Fiscal Studies recently examined the impact of the two-child limit on early years development (up to the age of five) and found no measurable effect on school readiness.

This finding may have come as a surprise to campaigners who argue that the policy harms child development. But it is consistent with evidence from the US which found that giving extra money to poorer families had no impact on early child development.

It seems then that the short-term effects of lifting the two-child benefit cap may not be significant. But longer-term influences, particularly on educational attainment, health and lifetime earnings could still emerge.

The second area of potential economic benefit relates to encouraging people to have more children. The logic here is that reinstating benefits payments for more than two children would lead to higher fertility rates (the average number of children a woman has over her lifetime).

This is particularly relevant given that birth rates in the UK have declined significantly in recent years from 812,970 births in 2012 to 694,685 in 2021.

As the population ages and lives longer, there is a risk that a shrinking working-age population will threaten economic prosperity. This is partly through a reduction in the number of workers supporting those who are not working, but also through a reduction in innovation, the key driver of economic growth.

Yet evidence that the two-child limit has significantly deterred parents from having more children is weak. Research suggests only a small decline in birth rates among low-income households likely to be affected by the policy.

Child poverty

Another important consideration is the policy’s effect on the labour market. Evidence indicates that the introduction of the two-child limit led to small increases in hours worked, and an increased likelihood of mothers of three children entering the workforce. This implies that the two-child limit incentivised some people to work more.

If scrapping the cap reverses these effects, the fiscal cost could be even higher because of reduced tax revenue and lower economic output.

That said, this reduction in employment could also be framed as a benefit. Stricter benefit rules that increase employment may also lead to negative mental health outcomes, which also carry social and fiscal costs.

From an efficiency standpoint then, the case for scrapping the two-child limit is ambiguous. The evidence on its impact on fertility and childhood outcomes is mixed, and there may be a effects on the labour market whose net benefit is uncertain.

But from an equity perspective, the case is much stronger. It is easy to argue that reducing poverty is a desirable policy goal in its own right, regardless of whether it leads to other measurable social benefits.

Scrapping the cap is one of the most cost-effective ways of reducing child poverty. The Resolution Foundation thinktank estimates that abolishing the two-child limit would lift around 500,000 children out of poverty and is the single most effective policy lever available to government. It may now be a lever that Reeves intends to pull.

Trump’s Latin America strategy risks creating a military quagmire

Source: The Conversation – UK – By Pablo Uchoa, PhD Candidate in the Institute of the Americas, UCL

The arrival of the world’s largest aircraft carrier, the USS Gerald R. Ford, in the Caribbean basin on November 11 has intensified fears of a large-scale conflict in the region. The carrier has been deployed as part of US president Donald Trump’s campaign against boats in the Caribbean and Pacific allegedly transporting drugs bound for the US.

But some experts suspect that the real objective is to support a possible US military strike aimed at toppling the regime of Nicolás Maduro in Venezuela. Trump has long accused the Venezuelan government of being a criminal organisation, offering US$50 million (£38 million) earlier in 2025 for information leading to Maduro’s arrest.

Trump recently authorised the CIA to conduct covert lethal operations inside Venezuela, adding that his administration was now considering operations on land. The deployment of the USS Gerald R. Ford, which has 4,000 sailors and dozens of aircraft on board, further raises the stakes.

However, US military action in Venezuela would carry immense risks. The Venezuelan government has long been preparing for an asymmetric conflict with the US, eccentric as this may have sounded in the past.

Venezuela’s military doctrine

In 2002, the Venezuelan government was subject to a US-backed coup attempt. This prompted Hugo Chávez, Venezuela’s leader at the time, to promote an overhaul of national military thinking to deal with a possible US invasion.

His strategy incorporated principles of “people’s war”, a Maoist tactic used extensively by Vietnamese military commander Vo Nguyen Giap in the Vietnam war. This tactic accepts ceding territory to an invading force initially, in favour of engaging the enemy in guerilla-style warfare until the conflict becomes impossible to sustain.

A key part of the tactic is that it blurs the boundaries between society and the battlefield, relying on the support and participation of the population. Reflecting on so-called people’s wars in the first half of the 19th century, Prussian military theorist Carl von Clausewitz observed that the strongest wars are those driven by the determination of the people.

The concept of people’s war and asymmetric warfare has been codified in anti-imperialist doctrines throughout the 20th century. This is especially true for the Vietnamese guerrilla leaders. But it was also adopted more loosely by insurgencies such as the Taliban, which fought Soviet forces in Afghanistan in the 1980s.

The Iraqi resistance against US forces in the early 2000s featured highly in Chávez’s mind. Venezuela’s then-president had thousands of copies of Spanish political scientist Jorge Verstrynge’s 2005 book, Peripheral Warfare and Revolutionary Islam, distributed within the Venezuelan army. The book draws on the experience of jihadist groups to emphasise the power of smaller, irregular formations in deciding asymmetric conflicts.

The Bolivarian Militia, a special branch of the Venezuelan armed forces created in 2008, embodies the doctrine of people’s war by incorporating civilians into national security mobilisation. Membership of the militia grew from 1.6 million in 2018 to 5 million by 2024, according to official figures. Under Maduro, the Venezuelan government has said it wants to expand membership to 8.5 million people.

The goal of the militia is not to duplicate conventional Venezuelan armed forces, but to extend their presence across the country. Venezuela’s territorial defence system is based on military deployments at regional, state and municipal levels, with personnel and missions assigned according to local geography and population.

Under Chávez, this system was broken down into much smaller units, covering specific municipal areas and communities. This level of capillarity is possible because it relies on civilian soldiers from the Bolivarian Militia and their profound knowledge of local areas.

For a large proportion of militia men and women, especially older members, their main task would not involve weapons. They would probably be tasked with carrying out what the government calls “popular intelligence” – in other words, surveillance.

This has already been reinforced with a recently launched mobile phone app which allows Venezuelans to report “everything they see and hear” in their neighbourhood that they consider suspicious.

Political and economic quagmire

A powerful US invading force would probably be allowed to march into Venezuela relatively easily. The problem would be the ensuing political and military quagmire that Venezuela’s military doctrine has been designed to create.

There are many uncertainties surrounding this scenario. On the Venezuelan side, civil-military coordination in wartime would be highly complex. Large-scale exercises have seen hundreds of thousands of regular troops, militia members and police simulating possible wartime scenarios. But their logistics have never been tested in real life.

Another uncertainty concerns the cohesion of combatants. Trump’s hardline posture towards Venezuela could trigger a “rally round the flag” effect, reinforcing loyalty to the government in the early stages of war. But the ideological commitment of militia members in a protracted scenario is another question.

On the US side, Trump’s plan for Venezuela remains unclear. Assuming Washington’s aim is to install an opposition government, it’s not obvious how such an administration could survive in the days and weeks after taking power. A conflict could also trigger another wave of Venezuelan emigration, adding to the 8 million-strong diaspora living mostly in Latin American countries.

The Bolivarian doctrine hopes that the prospect of “another Iraq” in Latin America serves as a deterrent against US intervention in Venezuela. But it is unclear whether Trump is taking this prospect seriously.

The US president reportedly considers Venezuela “unfinished business” from his first term in office. At that time, he imposed harsh sanctions on Venezuela’s oil sector, saying in 2023: “When I left, Venezuela was ready to collapse. We would’ve taken it over, and would’ve gotten all that oil.”

Yet a military solution now would still risk leaving this business unfinished for the foreseeable future.
