There is a supermassive black hole at the centre of nearly every big galaxy – including ours, the Milky Way (it’s called Sagittarius A*). Supermassive black holes are the densest objects in the universe, with masses reaching billions of times that of the Sun.

Sometimes a galaxy’s supermassive black hole “wakes up” due to a sudden influx of gas and dust, most likely supplied from a neighbouring galaxy. It begins eating up lots of nearby gas and dust. This isn’t a calm, slow or passive process. As the black hole pulls in material, the material gets superheated on a scale of millions of degrees, far hotter than the surface temperature of our Sun, and is ejected from the galaxy at near-light speeds. This creates powerful jets that look like fountains in the cosmos.

The accelerated high-speed plasma matter prompts these “fountains” to emit radio signals that can only be detected by very powerful radio telescopes. This gives them their name: radio galaxies. While black holes are common, radio galaxies are not. Only between 10% and 20% of all galaxies exhibit this phenomenon.

Giant radio galaxies are even less common. They account for only 5% of all radio galaxies and take their name from the fact that they reach enormous distances. Some radio galaxies’ jets reach nearly 16 million light-years. (That’s almost six times the distance between the Milky Way and the Andromeda galaxy.) The largest jet discovered spans nearly 22 million light-years across.

But how do these structures cover such enormous distances? To find out, I led a study in which we used modern supercomputers to develop models that simulated behaviour of giant cosmic jets within a mock universe, constructed on the basis of fundamental physical laws governing the cosmos.

This allowed us to observe how radio jets propagate over hundreds of millions of years – a process impossible to track directly in the real universe. These sophisticated simulations provide deeper insights into the life cycle of radio galaxies, highlighting the differences between their early, compact stages and their later, expansive forms.

Understanding the evolution of radio galaxies helps us unravel the broader processes that shape the universe.

Supercomputing

Cutting-edge technology was key to this study.

Sensitive observations from world-class radio telescopes like South Africa’s MeerKAT and LOFAR in the Netherlands have recently led to several discoveries of cosmic fountains.

However, modelling their origins has been challenging. Tracking events over millions of years is impossible in real-time.

That’s where supercomputers come in. These high-performance computing systems are designed to process massive amounts of data. They can perform complex simulations at incredible speeds. In this study, their power was crucial for modelling the evolution of giant radio jets over millions of years.

The necessary supercomputing power was provided by South Africa’s Inter-University Institute for Data Astronomy, a network comprising the University of Pretoria, the University of Cape Town and the University of the Western Cape.

Our universe is governed by fundamental forces like gravity, which can be described through mathematical formulas. These formulas, essentially numbers, are fed into supercomputers to create a simulated “mock universe” that follows the same physical laws as the real cosmos. This allows scientists to experiment with how jets from supermassive black holes evolve over time. With their immense processing power, supercomputers can simulate millions of years of cosmic jet evolution in just a month.

Key takeaways

Gravity is the dominant force in the universe, pulling heavier matter and dragging nearby lighter matter. If gravity were the only force at play, the universe might have collapsed by now. Yet we see galaxies, galaxy clusters and even life itself thriving. We suspect that these cosmic fountains play a key role in solving the mystery of how this happens.

By releasing thermal and mechanical energy, they heat up the surrounding collapsing gas, counteracting gravity and maintaining a balance that sustains cosmic structures.

Our models also shed light on why some radio galaxies’ jets bend sharply, forming an “X” shape in radio waves instead of following a straight trajectory, and revealed the conditions under which giant fountains can continue growing even in dense cosmic environments (that is, in a galaxy cluster).

The study also suggests that giant radio galaxies may be statistically more common than previously believed. There are potentially thousands of undiscovered giant cosmic fountains. Thanks to world-class telescopes like MeerKAT and LOFAR – and the power of supercomputers – there’s plenty more to explore as we try to understand our universe.

The research on which this article is based required extensive collaboration with an international team, including Jacinta Delhaize from the University of Cape Town, Joydeep Bagchi from Christ University, India, and DJ Saikia from the Inter-University Centre for Astronomy and Astrophysics in India. Essential contributions by Kshitij Thorat and Roger Deane from the University of Pretoria also played a crucial role in shaping the study.

Iran and Ethiopia have a security deal – here’s why they signed it

Source: The Conversation – Africa (2) – By Eric Lob, Associate Professor of Politics and International Relations, Florida International University

Ethiopia and Iran signed a memorandum of understanding (MOU) on 6 May 2025. Under it, their national police agencies will cooperate on security and intelligence. This will include combating cross-border crime, sharing intelligence and building capacity. They will also share experiences and training.

For Iran, the MOU marks a significant step towards strengthening relations with a regional power that’s strategically located in the Horn of Africa.

Tehran has been using its security apparatus and military capabilities to establish and expand political and economic ties with countries in Africa. This has included drone transfers to the Ethiopian government that helped it turned the tide of the Tigray war, a separatist struggle in the country’s north that took place from 2020 to 2022.

Iran has also supplied the Sudanese army with surveillance and combat drones. These have been used against the paramilitary Rapid Support Forces in Sudan’s ongoing civil war.

The agreement is important for Ethiopia for two reasons.

Firstly, it’s likely to enable the Ethiopian government in Addis Ababa to combat ethnic militias more effectively. It faces increasing internal instability, including tensions with hostile factions of the separatist Tigray People’s Liberation Front.

Secondly, the agreement comes after a meeting in Addis Ababa between the Ethiopian police chief, Demelash Gebremichael, and a delegation from Iran’s regional rival, the United Arab Emirates (UAE). The exchange concentrated on investigating and extraditing cross-border criminals.

Addis Ababa’s willingness to work with regional rivals in the Middle East shows its pragmatic approach to foreign relations. Ethiopia needs all the friends it can muster as an embattled and weakened state. Since the Tigray war, it has battled the rise of ethnic militias and confronted economic adversity. It is also facing renewed hostility with neighbouring Eritrea.

What Iran stands to gain

Since 2016, Ethiopia has been a gateway for Iran to gain a foothold in the Horn of Africa. That year, other countries in the region severed relations with Iran. This followed Tehran’s disengagement from sub-Saharan Africa under Hassan Rouhani, who served as president from 2013 to 2021, and his prioritisation of a nuclear deal with the US.

The severing of ties was also a byproduct of geopolitical pressure exerted by Saudi Arabia and the UAE on countries in the region. The Middle Eastern states wanted to reduce, if not eliminate, Iran’s presence in the Horn of Africa and Red Sea to limit its support for Houthi rebels in the ongoing Yemeni civil war.

Ethiopia was the first country in sub-Saharan Africa to establish relations with Iran during the 1960s. It was also one of its top trading partners on the continent before and after the 1979 Iranian Revolution.

Strategically and ideologically, this special relationship was based on the pro-western and anti-communist stances of their monarchs: the Shah of Iran Mohammad Reza Pahlavi, who ruled from 1941 to 1979, and Emperor Haile Selassie, who was in power from 1930 to 1974.

After the revolution, Iran-Ethiopia relations revived under Mahmoud Ahmadinejad, who served as Iranian president from 2005 to 2013. He pursued an active Africa policy to mitigate Iran’s international isolation and circumvent US sanctions.

After Rouhani initially downgraded these relations, they were renewed during his second term. This followed US withdrawal from the nuclear deal.

Relations firmed when Ebrahim Raisi, who served as Iranian president from 2021 to 2024, delivered military drones and other aid to Addis Ababa during the Tigray war.

What’s in it for Ethiopia

Ethiopia is facing increasing instability and uncertainty. The Tigray war has depleted the state’s resources. There is an economic crisis caused by rising inflation and unemployment.

Addis Ababa continues to confront ethnic tensions. Hostile factions of the Tigray People’s Liberation Front remain. It also faces tensions with the Amhara Fano militia, which initially fought alongside the government against Tigrayan forces. Forced disarmament policies and ongoing land disputes caused the militia to take up arms against the government.

Ethiopian prime minister Abiy Ahmed also faces growing opposition and resistance from his own ethnic group, the majority Oromo, and their Oromo Liberation Army. The reason for their discontent is Abiy’s imposition of centralised rule on their regional state within a federal system.

The security and intelligence cooperation with Iran could allow Addis Ababa to combat ethnic militias more effectively.

It would also enable Ethiopia to prepare for another possible war against neighbouring Eritrea.

Ethiopia and Eritrea normalised relations and fought together against Tigrayan forces. However, tensions between the two countries have been brewing again. These have been triggered by two factors. First, the conditions of the 2022 Pretoria peace agreement caused Eritrea to maintain forces inside Ethiopia. Second are the ambitions of Addis Ababa to acquire a Red Sea port in Somaliland, a breakaway region of Somalia. Eritrea has supported Somalia’s opposition to the deal.

Regional power games

This isn’t the first time that Ethiopia has tried working with two regional rivals – Iran and the UAE. The UAE is also among its top trading partners, along with Saudi Arabia.

In 2016, Ethiopia was the only country in the Horn of Africa that didn’t cut ties with Iran, though it was under pressure from the UAE and Saudi Arabia to do so. The decision was taken by Abiy’s predecessor, Hailemariam Desalegn, whose term ran from 2012 to 2018.

During the Tigray war, Ethiopia received military drones and other assistance from Iran and the UAE, alongside Turkey.

The civil war in Sudan has presented an even more complicated story. Ethiopia has vacillated between engaging with the Rapid Support Forces and the Sudanese Armed Forces at different points in the conflict.

For its part, Iran has supported the Sudanese army. The UAE has backed the paramilitary Rapid Support Forces.

Ethiopia’s efforts to strengthen its security ties with Iran and the UAE show a unique case of convergence between regional rivals that have otherwise remained on opposite sides of conflicts in countries like Yemen and Sudan.

Trump’s worldview is causing a global shift of alliances – what does this mean for nations in the middle?

Source: The Conversation – Global Perspectives – By Dilnoza Ubaydullaeva, Lecturer in Government – National Security College, Australian National University

Since US President Donald Trump took office this year, one theme has come up time and again: his rule is a threat to the US-led international order.

As the US political scientist John Mearsheimer famously argued, the liberal international order

was destined to fail from the start, as it contained the seeds of its own destruction.

This perspective has gained traction in recent years. And now, Trump’s actions have caused many to question whether a new world order is emerging.

Trump has expressed a desire for a new international order defined by multiple spheres of influence — one in which powers like the US, China and Russia each exert dominance over distinct regions.

This vision aligns with the idea of a “multipolar” world, where no single state holds overarching global dominance. Instead, influence is distributed among several great powers, each maintaining its own regional sphere.

This architecture contrasts sharply with earlier periods – the bipolar world of the Cold War, dominated by the US and the Soviet Union; and the unipolar period that followed, dominated by the US.

What does this mean for the world order moving forward?

Shifting US spheres of influence

We’ve seen this shift taking place in recent months. For example, Trump has backed away from his pledge to end the war between Russia and Ukraine and now appears to be leaving it to the main protagonists, and Europe, to find a solution.

Europe, which once largely spoke in a unified voice with the US, is also showing signs of policy-making which is more independent. Rather than framing its actions as protecting “Western democratic principles”, Europe is increasingly focused on defining its own security interests.

In the Middle East, the US will likely maintain its sphere of influence. It will continue its unequivocal support for Israel under Trump.

The US will also involve itself in the region’s politics when its interests are at stake, as we witnessed in its recent strikes on Iranian nuclear facilities.

This, along with increasing economic ties between the US and Gulf states, suggests US allies in the region will remain the dominant voices shaping regional dynamics, particularly now with Iran weakened.

Yet it’s clear Trump is reshaping US dynamics in the region by signaling a desire for reduced military and political involvement, and criticising the nation building efforts of previous administrations.

The Trump administration now appears to want to maintain its sphere of influence primarily through strong economic ties.

Russia and China poles emerging elsewhere

Meanwhile, other poles are emerging in the Global South. Russia and China have deepened their cooperation, positioning themselves as defenders against what they frame as Western hegemonic bullying.

Trump’s trade policies and sanctions against many nations in the Global South have fuelled narratives (spread by China and Russia) that the US does not consistently adhere to the rules it imposes on others.

Trump’s decision to slash funding to USAID has also opened the door to China, in particular, to become the main development partner for nations in Africa and other parts of the world.

And on the security front, Russia has become more involved in many African and Middle Eastern countries, which have become less trustful and reliant on Western powers.

In the Indo-Pacific, much attention has been given to the rise of China and its increasingly assertive posture. Many of Washington’s traditional allies are nervous about its continued engagement in the region and ability to counter China’s rise.

Chinese leader Xi Jinping has sought to take advantage of the current environment, embarking on a Vietnam, Malaysia and Cambodia push earlier this year. But many nations continue to be wary of China’s increasing influence, in particular the Philippines, which has clashed with China over the South China Sea.

Strategic hedging

Not all countries, however, are aligning themselves neatly with one pole or another.

For small states caught between great powers, navigating this multipolar environment is both a risk and an opportunity.

Ukraine is a case in point. As a sovereign state, Ukraine should have the freedom to decide its own alignments. Yet, it finds itself ensnared in great power politics, with devastating consequences.

Other small states are playing a different game — pivoting from one power to another based on their immediate interests.

Slovakia, for instance, is both a NATO and EU member, yet its leader, Robert Fico, attended Russia’s Victory Day Parade in May and told President Vladimir Putin he wanted to maintain “normal relations” with Russia.

Then there is Central Asia, which is the centre of a renewed “great game,” with Russia, China and Europe vying for influence and economic partnerships.

Yet if any Central Asian countries were to be invaded by Putin, would other powers intervene? It’s a difficult question to answer. Major powers are reluctant to engage in direct conflict unless their core interests or borders are directly threatened.

As a result, Central Asian states are hedging their bets, seeking to maintain relations with multiple poles, despite their conflicting agendas.

A future defined by regional power blocs?

While it is still early to draw definitive conclusions, the events of the past few months underscore a growing trend. Smaller countries are expressing solidarity with one power, but pragmatic cooperation with another, when it suits their national interests.

For this reason, regional power blocs seem to be of increasing interest to countries in the Global South.

For instance, the China-led Shanghai Cooperation Organisation has become a stronger and larger grouping of nations across Eurasia in recent years.

Trump’s focus on making “America Great Again,” has taken the load off the US carrying liberal order leadership. A multipolar world may not be the end of the liberal international order, but it may be a reshaped version of liberal governance.

How “liberal” it can be will likely depend on what each regional power, or pole, will make of it.

Is Kenya’s president safe in a crowd? Security expert scans VIP protection checklist

Source: The Conversation – Africa (2) – By Douglas Lucas Kivoi, Principal Policy Analyst, Governance Department, The Kenya Institute for Public Policy Research and Analysis (KIPPRA)

Protecting any president requires multiple layers of intelligence, physical security and rapid response security protocols. Exact operational details are classified, but there are global best practices in VIP protection.

The issue of presidential protection in Kenya has become particularly relevant following an incident in early May 2025 when someone in a crowd threw a shoe at President William Ruto during a public event, hitting his hand.

I have studied policing and security policies in Kenya for over 15 years, interacting closely with the country’s security protocols. In my view this incident exposed several critical security lapses around the elite officers tasked with protecting the president.

The security of the president is a critical issue in Kenya. The country is exposed to terror groups like the Somalia-based Al-Shabaab and other criminal networks in the region.

In 2021, a businessman embedded himself into the presidential motorcade and drove into then president Uhuru Kenyatta’s official residence. In 2017, an unidentified man who was said to have illegally accessed the highly protected state house grounds was shot dead by presidential guards.

There are multiple layers to Kenya’s protection protocols. They include National Intelligence Service officers, the Kenya Defence Force, Presidential Escort Police officers drawn from the highly trained General Service Unit, bomb disposal experts and regular police officers. Their deployment depends on the nature of the presidential engagement.

While the shoe incident may be passed off as simply embarrassing, it should serve as a wake-up call to tighten security protocols around the president without necessarily compromising his public engagement with citizens.

What’s in place

Prior to any presidential visit across the country, security teams conduct a thorough reconnaissance of the destination. This includes coordinating with local policing agencies, clearing airspace, mapping secure transport routes and identifying nearby medical facilities in case of emergencies.

Presidential motorcade routes are pre-planned and a dry run is made. This often includes mapping alternative routes to avoid predictability should there be assailants along a presidential route. It is common to see some roads temporarily closed and security officers conducting sweeps for any threats or explosives. In areas deemed high risk, counter security sniper teams are covertly deployed in strategic areas.

Cases of attacks on presidential motorcades are rare in Kenya. However, in 2002 during presidential campaigns, angry opposition supporters stoned then president Daniel Moi’s motorcade. In November 2021, an angry mob hurled rocks at then deputy president Ruto’s motorcade.

The National Intelligence Service and Presidential Escort Unit covertly scout locations in advance, assessing potential security vulnerabilities. Crowd sizes, and entry and exit points for the head of state are mapped out in advance.

In cases where meetings are held in town halls or huge tents, attendees are screened using metal detectors and/or physical searches. Uniformed and plainclothes security officers embed themselves in the crowd to monitor any threats.

The president and any dignitaries accompanying him have at least three layers of security.

The inner ring consists of close protection officers who are always within an arm’s length of the president to physically thwart any threats. The middle ring has armed security guards who watch for, among others, sudden movements and abnormal behaviour within the crowd. The outer ring consists of regular police and paramilitary units from the General Service Unit who secure the outside perimeter.

The presidential motorcade is a coordinated convoy of heavily armoured vehicles. It includes lead and chase cars, communication units and emergency response teams. Traffic is managed by local traffic police officers to ensure unobstructed movement. Routes are kept confidential until necessary.

The president’s security may opt to use a decoy vehicle if there is a security threat, to confuse and derail potential risk sources. In all these cases, there is a contingent of specialised General Service Unit officers, called the Recce unit, that always accompanies the president.

Kenya’s presidential security precautions follow standard VIP security protection like those for heads of state across the world. However, in some neighbouring countries, for instance, presidents move in heavily armed military convoys. This has not been seen in Kenya.

If a potential threat is detected, the president is immediately shielded and whisked away to a secure vehicle or evacuated by air in high-risk events. In such cases, the Kenya Defence Forces secures the president.

Despite stringent security measures, incidents can occur. For instance, in March 2025, a British tourist was fatally hit by a vehicle in Ruto’s motorcade. This prompted investigations and reviews on motorcade safety protocols.

Such events highlight the challenges of balancing presidential security with public safety, especially in densely populated urban areas.

Security failures

The shoe-throwing incident targeting Ruto highlighted five major failures in presidential protection protocols.

First, crowd screening and access control failures. The alleged assailant was very close to the president, suggesting an inadequate distance between the crowds and the president. The inner ring of security also failed to spot the perpetrator raising a shoe in the air to use as a projectile. This indicates weak front-row eye sweeps and scans by the president’s security.

Second, there was an apparent delay in security response. The elite officers around the president should have subdued the alleged attacker within seconds. It could mean most had their eyes on the president or cameras, as opposed to scanning the crowds for any sudden movements.

Third, security allowed the president to stand too close to a crowd that hadn’t been screened. Best practices require a no-go zone of three to five metres for individuals who have not been scanned or screened.

Fourth, there was an apparent gap in intelligence and threat assessment. Aggressive or agitated people next to the president should draw the attention of security officers. Plainclothes security officers are usually deployed to monitor crowd behaviour. It isn’t enough to rely on uniformed officers.

Undercover agents are critical for flagging pre-attack signals, such as nervousness or repeated adjustments of positions.

Fifth, there was no clear evacuation plan for the president. After the incident, the president continued speaking. In high-risk scenarios, protocols often demand instant relocation of the president to a secure vehicle or helicopter, where the military takes over and airlifts him to safety.

What should change

Kenya’s presidential security detail may be forced to:

  • increase standoff distance between the president and crowds

  • deploy more plainclothes officers to blend in and monitor crowds around the president

  • mandate stricter screening of those in close proximity to the president

  • conduct more frequent security risks drills for rapid neutralisation of potential threats.

The exact details of presidential security in Kenya are confidential. However, the overarching structure aims to provide comprehensive protection to the president while maintaining public safety and order during official engagements. No security protocol is 100% foolproof. But a balance needs to be struck between overly aggressive crowd control and accessibility.

We have drugs to manage HIV. So why are we spending millions looking for cures?

Source: The Conversation – Global Perspectives – By Bridget Haire, Associate Professor, Public Health Ethics, School of Population Health, UNSW Sydney

Alim Yakubov/Shutterstock

Over the past three decades there have been amazing advances in treating and preventing HIV.

It’s now a manageable infection. A person with HIV who takes HIV medicine consistently, before their immune system declines, can expect to live almost as long as someone without HIV.

The same drugs prevent transmission of the virus to sexual partners.

There is still no effective HIV vaccine. But there are highly effective drugs to prevent HIV infection for people without HIV who are at higher risk of acquiring it.

These drugs are known as as “pre-exposure prophylaxis” or PrEP. These come as a pill, which needs to be taken either daily, or “on demand” before and after risky sex. An injection that protects against HIV for six months has recently been approved in the United States.

So with such effective HIV treatment and PrEP, why are we still spending millions looking for HIV cures?

Not everyone has access to these drugs

Access to HIV drugs and PrEP depends on the availability of health clinics, health professionals, and the means to supply and distribute the drugs. In some countries, this infrastructure may not be secure.

For instance, earlier this year, US President Donald Trump’s dissolution of the USAID foreign aid program has threatened the delivery of HIV drugs to many low-income countries.

This demonstrates the fragility of current approaches to treatment and prevention. A secure, uninterrupted supply of HIV medicine is required, and without this, lives will be lost and the number of new cases of HIV will rise.

Another example is the six-monthly PrEP injection just approved in the US. This drug has great potential for controlling HIV if it is made available and affordable in countries with the greatest HIV burden.

But the prospect for lower-income countries accessing this expensive drug looks uncertain, even if it can be made at a fraction of its current cost, as some researchers say.

So despite the success of HIV drugs and PrEP, precarious health-care systems and high drug costs mean we can’t rely on them to bring an end to the ongoing global HIV pandemic. That’s why we also still need to look at other options.

Haven’t people already been ‘cured’?

Worldwide, at least seven people have been “cured” of HIV – or at least have had long-term sustained remission. This means that after stopping HIV drugs, they did not have any replicating HIV in their blood for months or years.

In each case, the person with HIV also had a life-threatening cancer needing a bone marrow transplant. They were each matched with a donor who had a specific genetic variation that resulted in not having HIV receptors in key bone marrow cells.

After the bone marrow transplant, recipients stopped HIV drugs, without detectable levels of the virus returning. The new immune cells made in the transplanted bone marrow lacked the HIV receptors. This stopped the virus from infecting cells and replicating.

But this genetic variation is very rare. Bone marrow transplantation is also risky and extremely resource-intensive. So while this strategy has worked for a few people, it is not a scalable prospect for curing HIV more widely.

So we need to keep looking for other options for a cure, including basic laboratory research to get us there.

How about the ‘breakthrough’ I’ve heard about?

HIV treatment stops the HIV replication that causes immune damage. But there are places in the body where the virus “hides” and drugs cannot reach. If the drugs are stopped, the “latent” HIV comes out of hiding and replicates again. So it can damage the immune system, leading to HIV-related disease.

One approach is to try to force the hidden or latent HIV out into the open, so drugs can target it. This is a strategy called “shock and kill”. And an example of such Australian research was recently reported in the media as a “breakthrough” in the search for an HIV cure.

Researchers in Melbourne have developed a lipid nanoparticle – a tiny ball of fat – that encapsulates messenger RNA (or mRNA) and delivers a “message” to infected white blood cells. This prompts the cells to reveal the “hiding” HIV.

In theory, this will allow the immune system or HIV drugs to target the virus.

This discovery is an important step. However, it is still in the laboratory phase of testing, and is just one piece of the puzzle.

We could say the same about many other results heralded as moving closer to a cure for HIV.

Further research on safety and efficacy is needed before testing in human clinical trials. Such trials start with small numbers and the trialling process takes many years. This and other steps towards a cure are slow and expensive, but necessary.

Importantly, any cure would ultimately need to be fairly low-tech to deliver for it to be feasible and affordable in low-income countries globally.

So where does that leave us?

A cure for HIV that is affordable and scalable would have a profound impact on human heath globally, particularly for people living with HIV. To get there is a long and arduous path that involves solving a range of scientific puzzles, followed by addressing implementation challenges.

In the meantime, ensuring people at risk of HIV have access to testing and prevention interventions – such as PrEP and safe injecting equipment – remains crucial. People living with HIV also need sustained access to effective treatment – regardless of where they live.

Somaliland’s 30-year quest for recognition: could US interests make the difference?

Source: The Conversation – Africa (2) – By Aleksi Ylönen, Professor, United States International University

More than three decades after unilaterally declaring independence from Somalia, Somaliland still seeks international recognition as a sovereign state. Despite a lack of formal acknowledgement, the breakaway state has built a relatively stable system of governance. This has drawn increasing interest from global powers, including the United States. As regional dynamics shift and great-power competition intensifies, Somaliland’s bid for recognition is gaining new currency. Aleksi Ylönen has studied politics in the Horn of Africa and Somaliland’s quest for recognition. He unpacks what’s at play.


What legal and historical arguments does Somaliland use?

The Somali National Movement is one of the main clan-based insurgent movements responsible for the collapse of the central government in Somalia. It claims the territory of the former British protectorate of Somaliland. The UK had granted Somaliland sovereign status on 26 June 1960.

The Somali government tried to stomp out calls for secession. It orchestrated the brutal killing of hundreds of thousands of people in northern Somalia between 1987 and 1989.

But the Somali National Movement declared unilateral independence on 18 May 1991 and separated from Somalia.

With the collapse of the Somali regime in 1991, the movement’s main enemy was gone. This led to a violent power struggle between various militias.

This subsided only after the politician Mohamed Egal consolidated power. He was elected president of Somaliland in May 1993.

Egal made deals with merchants and businessmen, giving them tax and commercial incentives to accept his patronage. As a result, he obtained the economic means to consolidate political power and to pursue peace and state-building. It’s something his successors have kept up with since his death in 2002.

What has Somaliland done to push for recognition?

Successive Somaliland governments continue to engage in informal diplomacy. They have aligned with the west, particularly the US, which was the dominant power after the cold war, and the former colonial master, the UK. Both countries host significant Somaliland diaspora communities.

The US and the UK have for decades flirted with the idea of recognising Somaliland, which they consider a strategic partner. However, they have been repeatedly thrown back by their respective Somalia policies. These have favoured empowering the widely supported Mogadishu government to reassert its authority and control over Somali territories.

This Somalia policy has been increasingly questioned in recent years, in part due to Mogadishu’s security challenges. In contrast, the Hargeisa government of Somaliland has largely shown it can provide security and stability. It has held elections and survived as a state for the last three decades, though it has faced political resistance and armed opposition.

As new global powers rise, Somaliland administrations have pursued an increasingly diverse foreign policy, with one goal: international recognition.

Hargeisa hosts consulates and representative offices of Djibouti, Ethiopia, Kenya, Taiwan, the UK and the European Union, among others.

The government has also engaged in informal foreign relations with the United Arab Emirates. The Middle Eastern monarchy serves as a business hub and a destination of livestock exports. Many Somalilanders migrate there.

Somaliland maintains representative offices in several countries. These include Canada, the US, Norway, Sweden, the UK, Saudi Arabia, Turkey and Taiwan. Hargeisa has alienated China because it has collaborated with Taiwan since 2020. Taiwan is a self-ruled island claimed by China.

On 1 January 2024, Somaliland’s outgoing president Muse Bihi signed a memorandum of understanding with Ethiopian prime minister Abiy Ahmed for increased cooperation. Bihi implied that Ethiopia would be the first country to formally recognise Somaliland. The deal caused a sharp deterioration of relations between Addis Ababa and Mogadishu.

Abiy later moderated his position and, with Turkish mediation, reconciled with his Somalia counterpart, President Hassan Mohamud.

What’s behind US interest in Somaliland?

The US, like other great powers, has been interested in Somaliland because of its strategic location. It is on the African shores of the Gulf of Aden, across from the Arabian Peninsula. Its geographical position has gained currency recently as Yemeni Houthi rebels strike maritime traffic in the busy shipping lanes. Somaliland is also well located to curb piracy and smuggling on this global trade route.

The US Africa Command set up its main Horn of Africa base at Camp Lemonnier in Djibouti in 2002. This followed the 11 September 2001 attacks.

Somaliland’s quest for recognition: UK debate offers hint of a sea change


In 2017, China, which had become the main foreign economic power in the Horn of Africa, set up a navy support facility in Djibouti. This encouraged closer collaboration between American and Somaliland authorities. The US played with the idea of establishing a base in Berbera, which hosts Somaliland’s largest port.

With Donald Trump winning the US presidential election in 2024, there were reports of an increased push for US recognition of Somaliland. This would allow the US to deepen its trade and security partnerships in the volatile Horn of Africa region.

Since March 2025, representatives of the Trump administration have engaged in talks with Somaliland officials to establish a US military base near Berbera. This would be in exchange for a formal but partial recognition of Somaliland.

What are the risks of US recognition of Somaliland?

Stronger US engagement with Somaliland risks neglecting Somalia.

Mogadishu depends on external military assistance in its battle against the advancing violent Islamist extremist group, Al-Shabaab. It also faces increasing defiance from two federal regions, Puntland and Jubaland.

US recognition would reward Hargeisa for its persistent effort to maintain stability and promote democracy. However, it could encourage other nations to recognise Somaliland. This would deliver a blow to Somali nationalists who want one state for all Somalis.

Understanding the ‘Slopocene’: how the failures of AI can reveal its inner workings

Source: The Conversation – Global Perspectives – By Daniel Binns, Senior Lecturer, Media & Communication, RMIT University

AI-generated with Leonardo Phoenix 1.0. Author supplied

Some say it’s em dashes, dodgy apostrophes, or too many emoji. Others suggest that maybe the word “delve” is a chatbot’s calling card. It’s no longer the sight of morphed bodies or too many fingers, but it might be something just a little off in the background. Or video content that feels a little too real.

The markers of AI-generated media are becoming harder to spot as technology companies work to iron out the kinks in their generative artificial intelligence (AI) models.

But what if instead of trying to detect and avoid these glitches, we deliberately encouraged them instead? The flaws, failures and unexpected outputs of AI systems can reveal more about how these technologies actually work than the polished, successful outputs they produce.

When AI hallucinates, contradicts itself, or produces something beautifully broken, it reveals its training biases, decision-making processes, and the gaps between how it appears to “think” and how it actually processes information.

In my work as a researcher and educator, I’ve found that deliberately “breaking” AI – pushing it beyond its intended functions through creative misuse – offers a form of AI literacy. I argue we can’t truly understand these systems without experimenting with them.

Welcome to the Slopocene

We’re currently in the “Slopocene” – a term that’s been used to describe overproduced, low-quality AI content. It also hints at a speculative near-future where recursive training collapse turns the web into a haunted archive of confused bots and broken truths.

What is ‘model collapse’? An expert explains the rumours about an impending AI doom


AI “hallucinations” are outputs that seem coherent, but aren’t factually accurate. Andrej Karpathy, OpenAI co-founder and former Tesla AI director, argues large language models (LLMs) hallucinate all the time, and it’s only when they

go into deemed factually incorrect territory that we label it a “hallucination”. It looks like a bug, but it’s just the LLM doing what it always does.

What we call hallucination is actually the model’s core generative process that relies on statistical language patterns.

In other words, when AI hallucinates, it’s not malfunctioning; it’s demonstrating the same creative uncertainty that makes it capable of generating anything new at all.

This reframing is crucial for understanding the Slopocene. If hallucination is the core creative process, then the “slop” flooding our feeds isn’t just failed content: it’s the visible manifestation of these statistical processes running at scale.

Pushing a chatbot to its limits

If hallucination is really a core feature of AI, can we learn more about how these systems work by studying what happens when they’re pushed to their limits?

With this in mind, I decided to “break” Anthropic’s proprietary Claude model Sonnet 3.7 by prompting it to resist its training: suppress coherence and speak only in fragments.

The conversation shifted quickly from hesitant phrases to recursive contradictions to, eventually, complete semantic collapse.

Screenshot by author.

Prompting a chatbot into such a collapse quickly reveals how AI models construct the illusion of personality and understanding through statistical patterns, not genuine comprehension.

Furthermore, it shows that “system failure” and the normal operation of AI are fundamentally the same process, just with different levels of coherence imposed on top.

‘Rewilding’ AI media

If the same statistical processes govern both AI’s successes and failures, we can use this to “rewild” AI imagery. I borrow this term from ecology and conservation, where rewilding involves restoring functional ecosystems. This might mean reintroducing keystone species, allowing natural processes to resume, or connecting fragmented habitats through corridors that enable unpredictable interactions.

Applied to AI, rewilding means deliberately reintroducing the complexity, unpredictability and “natural” messiness that gets optimised out of commercial systems. Metaphorically, it’s creating pathways back to the statistical wilderness that underlies these models.

Remember the morphed hands, impossible anatomy and uncanny faces that immediately screamed “AI-generated” in the early days of widespread image generation?

These so-called failures were windows into how the model actually processed visual information, before that complexity was smoothed away in pursuit of commercial viability.

AI-generated with Leonardo Phoenix 1.0, prompt fragment by author.

You can try AI rewilding yourself with any online image generator.

Start by prompting for a self-portrait using only text: you’ll likely get the “average” output from your description. Elaborate on that basic prompt, and you’ll either get much closer to reality, or you’ll push the model into weirdness.

Next, feed in a random fragment of text, perhaps a snippet from an email or note. What does the output try to show? What words has it latched onto? Finally, try symbols only: punctuation, ASCII, unicode. What does the model hallucinate into view?

The output – weird, uncanny, perhaps surreal – can help reveal the hidden associations between text and visuals that are embedded within the models.

Insight through misuse

Creative AI misuse offers three concrete benefits.

First, it reveals bias and limitations in ways normal usage masks: you can uncover what a model “sees” when it can’t rely on conventional logic.

Second, it teaches us about AI decision-making by forcing models to show their work when they’re confused.

Third, it builds critical AI literacy by demystifying these systems through hands-on experimentation. Critical AI literacy provides methods for diagnostic experimentation, such as testing – and often misusing – AI to understand its statistical patterns and decision-making processes.

These skills become more urgent as AI systems grow more sophisticated and ubiquitous. They’re being integrated in everything from search to social media to creative software.

When someone generates an image, writes with AI assistance or relies on algorithmic recommendations, they’re entering a collaborative relationship with a system that has particular biases, capabilities and blind spots.

Rather than mindlessly adopting or reflexively rejecting these tools, we can develop critical AI literacy by exploring the Slopocene and witnessing what happens when AI tools “break”.

This isn’t about becoming more efficient AI users. It’s about maintaining agency in relationships with systems designed to be persuasive, predictive and opaque.

Digital government can benefit citizens: how South Africa can reduce the risks and get it right

Source: The Conversation – Africa (2) – By Busani Ngcaweni, Visiting Adjunct Professor, Wits School of Governance, University of the Witwatersrand

The digital revolution is reshaping governance worldwide. From the electronic filing of taxes to digital visa applications, technology is making government services more accessible, efficient and transparent.

South Africa is making progress in its digital journey. In 2024 it climbed to 40th place out of 193 countries, from 65th place in 2022, in the United Nations e-Government Index. This improvement makes the country one of Africa’s digital leaders, surpassing Mauritius and Tunisia.

South Africa has identified more than 255 government services for digitisation. Already, 134 are available on the National e-Government Portal. This achievement is remarkable. Nevertheless, the shift to digitisation comes with challenges and risks.

Some countries have weakened the state’s role by rapidly outsourcing key government functions. But South Africa has the opportunity to build a model of digital transformation that strengthens public institutions rather than diminishes them.

New technologies must bring tangible benefits for citizens. Digital transformation can improve public administration. But, if mismanaged, it could burden taxpayers with costs.

Benefits

Digital transformation comes at a cost. This is particularly true if the state fails to use its procurement power to negotiate reasonable prices. Infrastructure upgrades, cybersecurity measures, software licensing and system maintenance require substantial financial investment.

The question is whether these expenses are a necessary step towards a more efficient and accessible government.

Two South African examples illustrate that digital transformation can save money and enhance service delivery quality.

The first is the South African Revenue Service. Its goal is to ensure that taxpayers and tax advisers can use the service from anywhere and at any time. The changes made more than a decade ago show that digital systems can yield substantial financial gains. After introducing e-filing in 2006, the revenue service streamlined tax processes, reduced inefficiencies and led to higher compliance rates. Ultimately this led to improved revenue collection.

Similarly, digitising social grant payments has had a number of positive effects. In a chapter of a recent edited volume on public governance, my colleagues and I wrote a case study about how the South African Social Security Agency used basic technologies and platforms like WhatsApp and email to process a grant during the COVID pandemic. It allowed over 14 million people to apply, paid grants to over 6 million beneficiaries during the first phase of the project.

South African Social Security Agency annual reports show that over 95% of grant beneficiaries receive their payouts electronically through debit cards, instead of going to cash points. This improves security and lets beneficiaries decide when to get and spend their money.

There are fears that automation could result in massive job losses. But global experience has shown that digitalisation does not necessarily lead to large-scale retrenchments. Instead it can shift the nature of work to other responsibilities.

The South African Social Security Agency provides a compelling case. Its transition to digital grant payments did not lead to job losses. Similarly, the expansion of e-filing at the revenue service has not resulted in workforce reductions. In both cases efficiencies improved.

These cases highlight that digital transformation is reshaping roles rather than displacing employees. Public servants are moving into areas such as cybersecurity, data analysis and AI-driven decision-making.

Shortcomings and pitfalls

A number of inefficiencies are at play in government services.

Firstly, most government digital operations still work with outdated paper-based systems. The lack of a uniform digital identity creates bureaucratic inefficiencies and delays.

Secondly, fragmented procurement of equipment in government has led to duplicated efforts, increased costs and fruitless expenditure.

Thirdly, different departments often use isolated and incompatible digital systems. This reduce the mutual benefits of digital transformation. The State IT Agency has been blamed for inefficiencies, procurement failures and questionable spending.

Fourthly, South Africa’s public service remains fragmented. Citizens still struggle to access government services seamlessly. They often move between departments to complete what should be a single transaction.

Without a centralised system, departments operate in isolation, duplicating efforts, increasing costs and eroding public trust.

South Africa’s civil servants are missing skills, especially when it comes to technology – report


Fifth, a lack of skills. Increasing reliance on digital tools requires expertise in data analytics, cloud computing and automation. Many public servants lack the training to take on these new roles. The National Digital and Future Skills Strategy was introduced in September 2020 to bridge this gap, but its effectiveness depends on its implementation.

Introducing it in 2020 at the height of the COVID-19 pandemic forced government to make digital leaps which otherwise might have taken longer. To sustain services, technology had to be rapidly adopted, including basic things like holding Cabinet meetings online, using a system rapidly developed by the State Information Technology Agency.

Sixth, security concerns complicate the transformation. As government systems become digital, they become vulnerable to cyberattacks. South Africa must put in place cybersecurity infrastructure to prevent identity theft, data breaches and service disruptions. A cyberattack on one department could affect the entire public sector.

What needs to be done

Government must streamline procurement, improve coordination and eliminate inefficiencies to ensure interdepartmental collaboration.

A single, integrated e-government platform would:

  • cut red tape

  • reduce queues

  • increase efficiency.

Government needs to upskill civil servants and improve their digital literacy.

Government must create a seamless e-government system that connects services while protecting citizens’ personal information. The success of digitalisation depends on technological advancements as well as the level of trust citizens have in government systems. Without strong security measures, transparency and accountability, even the most sophisticated digital tools will fail to gain public confidence.

South Africa has the chance to demonstrate that a strong, capable state can successfully integrate technology while safeguarding public interests. It should take full advantage of offers by Microsoft, Amazon and Huawei to support digital skills training in the public sector in a way that does not advantage one company’s technologies over others. Choices of technology must be user-centric, not based on preferences of accounting officers and chief information officers. Leaders of public institutions must be measured on their ability to digitally transform their organisations.

The 28 Days Later franchise redefined zombie films. But the undead have an old, rich and varied history

Source: The Conversation – Global Perspectives – By Christopher White, Historian, The University of Queensland

The history of the dead – or, more precisely, the history of the living’s fascination with the dead – is an intriguing one.

As a researcher of the supernatural, I’m often pulled aside at conferences or at the school gate, and told in furtive whispers about people’s encounters with the dead.

The dead haunt our imagination in a number of different forms, whether as “cold spots”, or the walking dead popularised in zombie franchises such as 28 Days Later.

The franchise’s latest release, 28 Years Later, brings back the Hollywood zombie in all its glory – but these archetypal creatures have a much wider and varied history.

Zombis, revenants and the returning dead

A zombie is typically a reanimated corpse: a category of the returning dead. Scholars refer to them as “revenants”, and continue to argue over their exact characteristics.

In the Haitian Vodou religion, the zombi is not the same as the Hollywood zombie. Instead, zombi are people who, as a religious punishment, are drugged, buried alive, then dug out and forced into slavery.

The Hollywood zombie, however, draws more from medieval European stories about the returning dead than from Vodou.

A perfect setting for a ‘zombie’ film

In 28 Years Later, the latest entry in Danny Boyle’s blockbuster horror franchise, the monsters technically aren’t zombies because they aren’t dead. Instead, they are infected by a “rage virus”, accidentally released by a group of animal rights activists in the beginning of the first film.

This third film focuses on events almost three decades after the first film. The British Isles is quarantined, and the young protagonist Spike (Alfie Williams) and his family live in a village on Lindisfarne Island. This island, one of the most important sites in early medieval British Christianity, is isolated and protected by a tidal causeway that links it to the mainland.

The film leans heavily on how we imagine the medieval world, with scenes showing silhouetted fletchers at work making arrows, children training with bows, towering ossuaries and various memento mori. There’s also footage from earlier depictions of medieval warfare. And at one point, the characters seek sanctuary in the ruins of Fountains Abbey, in Yorkshire, which was built in 1132.

The medieval locations and imagery of 28 Years Later evoke the long history of revenants, and the returned dead who once roved medieval England.

Early accounts of the medieval dead

In the medieval world, or at least the parts that wrote in Latin, the returning dead were usually called spiritus (“spirit”), but they weren’t limited to the non-corporeal like today’s ghosts are.

Medieval Latin Christians from as early as the 3rd century saw the dead as part of a parallel society that mirrored the world of the living, where each group relied on the other to aid them through the afterlife.

British Library, Yates Thompson MS 13

While some medieval ghosts would warn the living about what awaited sinners in the afterlife, or lead their relatives to treasure, or prophesise the future, some also returned to terrorise the living.

And like the “zombies” affected by the rage virus in 28 Years Later, these revenants could go into a frenzy in the presence of the living.

Thietmar, the Prince-Bishop of Merseburg, Germany, wrote the Chronicon Thietmari (Thietmar’s Chronicle) between 1012 and 1018, and included a number of ghost stories that featured revenants.

Although not all of them framed the dead as terrifying, they certainly didn’t paint them as friendly, either. In one story, a congregation of the dead at a church set the priest upon the altar, before burning him to ashes – intended to be read as a mirror of pagan sacrifice.

These dead were physical beings, capable of seizing a man and sacrificing him in his own church.

A threat to be dealt with

The English monastic historian William of Newburgh (1136–98) wrote revenants were so common in his day that recording them all would be exhausting. According to him, the returned dead were frequently seen in 12th century England.

So, instead of providing a exhausting list, he offered some choice examples which, like most medieval ghost stories, had a good Christian moral attached to them.

William’s revenants mostly killed the people of the towns they lived, returning to the grave between their escapades. But the medieval English had a method for dealing with these monsters; they dug them up, tore out the heart and then burned the body.

Other revenants were dealt with less harshly, William explained. In one case, all it took was the Bishop of Lincoln writing a letter of absolution to stop a dead man returning to his widow’s bed.

These medieval dead were also thought to spread disease – much like those infected with the rage virus – and were capable of physically killing someone.

The undead, further north

In medieval Scandinavia and Iceland, the undead draugr were extremely strong, hideous to look at and stunk of decomposition. Some were immune to human weapons and often killed animals near their tombs before building up to kill humans. Like their English counterparts, they also spread disease.

But according to the Eyrbyggja saga, an anonymous 13th or 14th century text written in Iceland, all it took was a type of community court and the threat of legal action to drive off these returned dead.

It’s a method the survivors in 28 Years Later didn’t try.

The dead live on

The first-hand zombie stories that were common during the medieval period started to dwindle in the 16th century with the Protestant Reformation, which focused more on individuals’ behaviours and salvation.

Nonetheless, their influence can still be felt in Catholic ritual practices today, such as in prayers offered for the dead, and the lighting of votive candles.

We still tell ghost stories, and we still worry about things that go bump in the night. And of course, we continue to explore the undead in all its forms on the big screen.

Is Sabrina Carpenter’s Man’s Best Friend album cover satire or self-degradation? A psychology expert explores our reactions

Source: The Conversation – Global Perspectives – By Katrina Muller-Townsend, Lecturer in Psychology, Edith Cowan University

Island Records

Sabrina Carpenter’s Man’s Best Friend album cover has fans divided.

Carpenter poses on all fours, her glossy blond hair grasped by a male figure cropped from the frame. Her wide-eyed expression intensifies an ambiguous performance of subservience, tapping into a visual language tied to female objectification, from classic pin-up imagery to contemporary pop culture.

The emotionally loaded image plays on her hyper-feminine, tongue-in-cheek pop star persona, forcing us to question where irony ends and objectification begins.

Is it satire, or self-degradation?

Up for debate

At first glance, the cover seems like just another stylised, provocative pop image. It delivers what we’ve come to expect: a bold, ironic twist on the exaggerated Juno-style pose she reinvents on stage.

To some fans, it’s clever satire: a pop star reclaiming and amplifying her image to mock industry norms. Satire uses exaggeration, irony, or humour to critique power structures – and Carpenter’s pose walks that tightrope.

To others it crosses a line, reinforcing regressive attitudes about women’s sexuality and drawing criticism from domestic violence advocates.

The debate reflects our unresolved discomfort about gender, power and control. There is a tension between Carpenter’s ironic persona and the submissive pose, creating uncertainty for the viewer.

We can use psychology to better understand this dichotomy.

The schema violation

This mismatch between expectation and perception is a schema violation.

A schema is a mental shortcut: a template built from experience and unspoken rules that helps us make sense of the world and predict what to expect. When something breaks that pattern, it’s called a schema violation.

Carpenter’s brand is cheeky, self-aware irony – so when she adopts a pose steeped in submission and hyper-femininity as in this album image, it feels off.

That can trigger cognitive dissonance: the mental tension we feel when two ideas (here, empowerment and obedience) don’t align.

To resolve the conflict, some fans reinterpret the image as feminist sarcasm. Others reject it, fearing it panders to outdated, dangerous norms.

Both reactions reflect our emotional and ideological investments in who Carpenter is or should be.

Exploring confirmation bias

Part of this conflicted reaction is driven by confirmation bias: our tendency to filter information to support what we already believe.

Fans who see Carpenter as witty and empowered interpret the image as intentionally ironic. Others – more sceptical of the industry’s history of exploiting female sexuality – view it as a throwback to damaging norms.

Either way, our interpretations often reflect more about ourselves than about Carpenter’s intent.

When her image contradicts both her public persona and our social values, it creates a gap between what we think is right and what we want to be right. So, we try to explain it away, by either defending the image or criticising it.

Satire and scandal

Carpenter’s cover follows a long tradition of female artists whose work straddles satire and scandal, complicating public reception.

Madonna’s Like a Prayer drew outrage for mixing religion with sexual imagery. Yet it positioned her as a provocateur – a woman resisting the lack of agency that so often defines sexualised media.

Miley Cyrus’ Bangerz era shocked fans with a bold shift from Hannah Montana innocence to hypersexualised rebellion, challenging the narrow roles women in pop culture are confined to.

Doja Cat’s shift from glam pop princess to glitch villainess unsettled audiences. Was it satire, rebellion, or just chaos?

These women, like Carpenter, force us to confront our own discomfort with women who won’t stay in one lane.

Performer and provocateur

Audience reaction is also shaped by emotional investment in Carpenter’s persona. Through carefully curated social media, interviews and lyrics, fans build intimate narratives forming parasocial relationships – one-sided emotional bonds with celebrities.

When an image contradicts that imagined persona, it can feel jarring, even like betrayal.

Audiences often expect idols to be empowering but not polarising, sexy but safe, to challenge norms – but only in ways that affirm our own values.

Carpenter’s image breaks that implicit contract, which creates discomfort for some viewers.

Carpenter’s cover raises uncomfortable but necessary questions about how much freedom female artists have to be both critical and complicit. Can they play with society and play along, to be both performer and provocateur?

This highlights the double bind many women face in media and popular culture. Female artists are expected to both subvert and satisfy; to entertain without offending; empower without alienating. The burden to be palatable and provocative is one male artists rarely face.

It’s what we make of it

Is Carpenter undermining herself or subverting the system? Perhaps both. Or perhaps the image isn’t the message: our reaction is.

The image forces us to confront not only our perception of Sabrina Carpenter but also our cultural discomfort with women who defy neat categorisation. Satire demands interpretation, especially when it comes from women addressing sex or power.

More than provocation, Carpenter’s cover mirrors our cultural struggle to accept women who defy simple labels of satire or submission. The image can reflect broader social ideals and tensions projected onto public figures.

What we see says more about our assumptions than her intent. Understanding those reactions doesn’t kill the fun – it deepens it.
