French President Emmanuel Macron denied Friday that a troubled fighter jet programme with Germany was dead, telling reporters Paris and Berlin were still working on that and other defence projects.

The multi-billion-euro project has faltered as disagreements persist between the firms involved — France’s Dassault Aviation and Airbus, which represents Germany and Spain.

Speaking ahead of a EU summit in Cyprus, Macron said that after morning talks with German Chancellor Friedrich Merz, the pair had instructed their respective defence ministries to carry on work on a range of issues, including the fighter jet.

“No, not at all,” Macron replied, asked by a journalist whether the European FCAS warplane programme was dead in the water.

“We had a good discussion this morning with the Chancellor and we have instructed our defence ministries to work on a number of areas, covering various topics –- not just the fighter jet,” Macron said.

“We are continuing to move forward. Europe has never needed unity, greater independence and greater sovereignty more than it does now,” he added.

The Future Combat Air System (FCAS) programme was launched in 2017 to replace France’s Rafale jets and the Eurofighter planes used by Germany and Spain.

It is often seen as a bellwether of defence and security cooperation between France and Germany as the two EU powerhouses seek to put up a united front in the face of a hostile Russia and wavering US security commitment.

Mediators tasked with salvaging the struggling initiative requested ten more days to deliver their conclusions, the French government said this week after reports suggesting the effort had failed to bear fruit.

A German government spokeswoman confirmed Macron and Merz discussed the fighter jet programme Friday morning and instructed defence ministers to continue work “on various aspects of cooperation and to agree on the next steps.”

“This work will be completed in the coming weeks,” she said.

Germany launches spying probe into Signal attacks targeting MPs

German prosecutors Friday launched a spying investigation into phishing attacks targeting lawmakers on the Signal messaging app, with an MP saying the latest Russia-directed plot against Germany was a “wake-up call”.

The wave of attacks has allegedly been directed at MPs from several parties including the speaker of parliament, a senior member of Chancellor Friedrich Merz’s CDU party, as well as civil servants, diplomats and journalists.

Germany, Kyiv’s biggest provider of miliary aid, has been battling a surge of cyberattacks, as well as espionage and sabotage plots since Russia’s full-scale invasion of Ukraine in 2022.

Moscow denies being behind any such actions.

The German Federal Prosecutor’s Office told AFP it had launched an investigation into the phishing attacks “based on an initial suspicion of espionage”.

It did not name Russia or give more details, but suspicion quickly fell on Moscow.

“The latest phishing attempt from Russia targeting German politicians and journalists is a wake-up call for all of us,” said Marc Heinrichmann, a CDU lawmaker who heads a committee overseeing the country’s intelligence services.

The attack makes “painfully clear” that everyone “must remain vigilant,” he said.

“What may seem like a harmless message at first glance could, in today’s world, be a targeted espionage attempt by foreign powers.”



– ‘Extremely worrying’ –



The attacks work by sending messages purporting to come from Signal support.

Victims are urged to hand over sensitive account information, which the attackers can then use to gain access to the victim’s chat groups and messages.

When the scam is successful, the hackers gain access to photos and files shared on Signal and can also impersonate the person whose account was compromised.

Many have moved from WhatsApp to the non-profit Signal in recent years because of privacy concerns after WhatsApp said it would share some metadata with parent company Meta, which also owns Facebook and Instagram.

German and foreign security services have been warning for months about the attacks, but the potential fallout in Germany is only just becoming clear.

CDU lawmaker Konstantin von Notz told AFP that the scale of the suspected attacks was “extremely worrying”.

“At present, no one can say with any certainty whether the integrity of MPs’ communications is still guaranteed,” he said.

Merz’s centre-right CDU party has so far not commented on how many of its lawmakers have been affected.

But earlier this week Der Spiegel news outlet reported that parliament speaker Julia Kloeckner’s Signal account had been compromised.

Kloeckner is a member of the CDU’s executive committee, whose members — including Merz — reportedly communicate via a Signal chat group, although no irregularities were detected on the chancellor’s phone.

His centre-left coalition partner, the SPD, and the far-left Die Linke have also said “a few” of their lawmakers have fallen victim.

Asked about the issue at a regular press briefing on Friday, a spokeswoman for the interior ministry said the attack is “probably led by a state actor”, adding that official warnings had been issued at the beginning of February and again last week.

Russia-linked hackers have been accused of being behind a string of cyberattacks in Germany.

Earlier this month, Germany intelligence services accused hackers associated with Russian military intelligence of infiltrating internet routers to obtain sensitive information.

The same group has also been accused of targeting air traffic control and of spreading disinformation ahead of last year’s general elections.

What is Signal and is it secure?

Signal, an end-to-end encrypted messaging app long considered one of the most secure in the world, has recently faced attacks from hackers accused of links to Russia.

Top German officials on Saturday blamed Moscow-backed groups for phishing attacks targeting senior politicians on the messaging app, raising questions about how secure Signal really is.

Similar phishing cases have been reported by Dutch and American users, with Google in February sounding the alarm over cyberattacks from Russia-aligned groups.

But what makes Signal different from other messaging apps, and how could one of the world’s most secure messaging apps be so widely targeted?

– How does it work? –

Signal’s end-to-end encryption means that any sent message travels in a scrambled form and can only be deciphered by the end user.

Nobody in between — not the company providing the service, not the internet provider, nor hackers intercepting the message — can read the content because they don’t have the keys to unlock it.

Signal is not the only messaging service to do this, but unlike WhatsApp and Apple’s iMessage, the app is controlled by an independent non-profit — not a big tech behemoth motivated by revenue. That has won it more trust with those concerned about privacy.

Signal also goes further than WhatsApp on data privacy, making metadata such as when the message was delivered and its recipient invisible even to the company itself.

And WhatsApp shares information with its parent company Meta and third parties, including phone numbers, mobile device information, and IP addresses.

For these reasons, Signal has long been a go-to messaging service for users particularly concerned about communications secrecy, such as people working in security professions, journalists, and their sources.

– Who owns Signal? –

Founded in 2012, Signal is owned by the Mountain View, California-based Signal Foundation.

Its history is linked to WhatsApp: the site was founded by cryptographer and entrepreneur Moxie Marlinspike, with an initial $50 million from WhatsApp co-founder Brian Acton.

Both Signal and WhatsApp, which was bought by Mark Zuckerberg in 2014, are based on the same protocol built by Marlinspike.

“We’re not tied to any major tech companies, and we can never be acquired by one either,” Signal’s website reads. Development is mainly supported by grants and donations.

Very outspoken compared to other Silicon Valley bosses, Signal’s president is Meredith Whittaker, who spent years working for Google and is a fierce critic of business models built on the extraction of personal data.

– Was Signal hacked? –

Signal’s encryption itself has not been broken.

Cyberattackers accused of Russian links did not target the encryption system directly.

Instead, recent attacks relied on phishing — tricking users into handing over access to their accounts.

The attacks work by sending messages purporting to come from Signal support, like fake security alerts or invites to join group chats.

Once users click on these links or enter sensitive account information, attackers can then gain access to messages and chat groups.

This means hackers gain access to data shared on Signal and can also impersonate the person whose account was compromised.

Signal did not immediately respond to requests for comment on the recent attacks.

Battle lines drawn over EU’s next big budget

April 24, 2026

Raziye Akkoc

EU leaders had their swords already drawn when they plunged into intense discussions Friday over the 27-country bloc’s next seven-year budget, with the usual frugal nations pushing to contain spending.

The European Commission last year proposed a budget of two trillion euros ($2.3 trillion) to pay for the bloc’s operations, from farm subsidies to research funding, for the 2028-2034 period.

European Union leaders took stock of their own position on Friday during talks in Cyprus, as they scramble to approve the final budget by the end of 2026.

Many EU countries which have to chip in most of the money have made it clear they oppose what would represent a sizable increase on the current budget, paving the way for difficult talks.

The leaders of Germany and the Netherlands, countries belonging to the so-called “frugals”, offered a stark message before heading into discussions with their EU counterparts in Nicosia.

German Chancellor Friedrich Merz ruled out higher debt — pushed by France — and said it was time for the EU to choose its battles.

“We will be setting new priorities. This means that we will also have to reduce spending in the European budget in other areas,” he told reporters.

He was echoed by Dutch Prime Minister Rob Jetten, who said the budget amount proposed by the commission “needs to be significantly reduced”.

It was “unacceptable” for the Netherlands, one of the largest contributors to the EU budget, to see its contribution “really explode”, Jetten added.



– ‘Compromise’ needed –



Any final agreement on the long-term budget will come after what are expected to be tense talks between the EU parliament and member states.

With critical elections next year including in France, the EU wants to get a deal before 2027 to avoid among others, the possible risk of a far-right French government causing a bigger headache in getting a deal over the line.

The next EU budget proposed that the bloc start paying off tens of billions of euros a year of its coronavirus-era debts, but some EU lawmakers oppose this and would like a rollover.

They also want an EU-wide tax on the world’s biggest tech companies.

“We cannot solve all the crises and the difficulties we are facing. We need new money to service old debt, and that is something that we will ask the member states to look at,” parliament chief Roberta Metsola said in Nicosia.

Commission chief Ursula von der Leyen said it was “indispensable” for the EU to develop new tax-based revenue sources.

“Without them, the choice is stark. It’s either higher national contributions or it’s lower spending capacity,” she told a press conference after talks.

Irish Prime Minister Micheal Martin, whose country will hold the rotating EU presidency from July after Cyprus, said he expected challenging negotiations.

“There will have to be compromise,” he said. “Some think the budget is too high as it is. Others think it’s not high enough.”

But the clock is ticking, European Council President Antonio Costa warned.

“We have a collective responsibility to reach an agreement by the end of the year,” Costa said after talks in Nicosia ended.

ILO names US official as number two amid grumbling over unpaid dues

After months of delay, the UN labour agency has appointed Trump administration official Sheng Li as its deputy director general, despite Washington’s failure to pay its dues for two years.

The International Labour Organisation (ILO) officially announced this week that Li, a high-level official at the US Department of Labor, would fill the post left vacant eight months ago.

The Geneva-based agency said Li would head the “policy cluster”, guiding and overseeing the work of five policy departrments.

The ILO had been without a deputy chief since last September, when Celeste Drake — also a US national — left.

In recent months, the rumoured looming appointment to the post of Nels Nordquist, a former top economic advisor to President Donald Trump, sparked outrage at the ILO, which had faced a barrage of criticism from the US administration.

In a memo published last August, the administration described the ILO as an organisation that “works to unionise foreign workers and punish US corporate interests abroad” — although those words and a decision to cancel $107 million in funding to the agency later mysteriously vanished from the text.

– US arrears –

The ILO’s deputy director post is usually held by a US national, but the agency’s staff union has raised questions about following that tradition at a time when Washington — traditionally the agency’s biggest donor — has failed to pay its 2024 and 2025 dues.

“We are still awaiting clarification regarding the reasons for this decision, particularly in light of certain unanswered questions concerning US contributions,” union chief Severine Deboos told AFP.

The United States, which in recent years has covered 22 percent of ILO’s funding, had as of April 24 accumulated arrears amounting to more than 173 million Swiss francs ($220 million) for the past two years, according to data on the agency website.

And it will also this year need to pay its 2026 contribution, amounting to 84 million francs.

“The US remains in arrears, as are many other member states who have yet to fulfil their financial commitments for the current biennium’s regular budget,” the ILO told AFP in an email Friday.

“These arrears have impacted the ILO’s cash flow, and we are actively engaging with the concerned countries to encourage the earliest possible settlement,” it added.

Like other UN organisations, the ILO is currently facing significant financial pressure and is undergoing major reforms as it strives to tighten its budget.

Reform plans that still need to be validated call for the slashing of around 120 positions by 2029 — a number that could be expanded by several hundreds more if further savings are required, ILO documents show.

Already last May, ILO chief Gilbert Houngbo said the closure of some 50 US-funded projects had forced the agency to lay off around 200 staff members out of a total of around 3,500 globally.

Maine governor nixes data center moratorium in state

Legislators in Maine earlier this month endorsed what would have been the first data center ban in the United States

 MARIO TAMA

The governor of Maine on Friday vetoed a temporary ban on building large data centers that aimed to rein in rampant construction driven by the AI race.

The buildout comes at a cost, as the power-hungry facilities strain local grids and drive up electricity bills.

Data centers also typically have massive footprints, taking up land that could be used for housing, businesses, recreation or green space.

Legislators in Maine earlier this month endorsed what would have been the first data center ban in the United States if it had been signed into law by Governor Janet Mills.

“A moratorium is appropriate given the impacts of massive data centers in other states on the environment and on electricity rates,” Mills said in a statement announcing the veto.

Mills explained that her veto was based on the bill’s failure to make an exception for a data center project in a part of the northeastern state where the closure of a mill three years ago had been a “devastating” economic blow.

“This decision is simply wrong,” said state reresentative Melanie Sachs, a sponsor of the bill.

“By vetoing this bill, Governor Mills isn’t just rejecting the advice of her own task force — she is resisting the will of a majority of Maine people.”

Public sentiment is hardening, with a recent Quinnipiac University poll finding 65 percent of Americans oppose having a data center built in their community.

A boom in generative artificial intelligence has sent data center demand skyrocketing, with dozens of projects springing up across the United States.

If it had become a law, the Maine bill would have paused new data center construction until November of next year.

It also called for the creation of a council to assess the risks and benefits of proposed data centers and provide input for planners.

Data center construction spending in the United States has surged in recent years, with tech firms pouring tens of billions of dollars into building out infrastructure amid the race to lead in AI.

Maine is among the US states that have seen home electricity bills soar in recent years, according to the US Energy Information Administration.

Crunch nuclear proliferation meeting at UN amid raging global wars

Amélie BOTTOLLIER-DEPOIS

Signatories of the landmark nuclear non-proliferation treaty will meet at the UN from Monday as hopes fade they can reach agreement and tensions soar between the atomic powers.

In 2022, during the last review of the treaty that is considered the cornerstone of non-proliferation, UN Secretary-General Antonio Guterres warned humanity was “one misunderstanding, one miscalculation away from nuclear annihilation.”

The situation has only worsened since then.

“I think there is a shared, if you will, sense of crisis by all states parties,” said Izumi Nakamitsu, the UN High Representative for Disarmament Affairs.

“We don’t have any bilateral arms control agreements between the two largest nuclear weapon states,” she said referring to the February expiration of the New Start treaty between Moscow and Washington.

“We are also beginning to see quantitative increase of nuclear capabilities in all nuclear weapon states.”

Nakamitsu said that mounting geopolitical tensions had halted the post-Cold War trend of disarmament.

The nuclear non-proliferation treaty (NPT), signed by almost all the countries on the planet — with notable exceptions like Israel, India, and Pakistan — aims to prevent the spread of nuclear weapons, to promote complete disarmament, and to encourage cooperation on civilian nuclear projects.

The nine nuclear-armed states — Russia, the United States, France, the United Kingdom, China, India, Pakistan, Israel, and North Korea — possessed 12,241 nuclear warheads in January 2025, according to the latest report by the Stockholm International Peace Research Institute (SIPRI).

The United States and Russia hold nearly 90 percent of nuclear weapons globally and have carried out major programs to modernize them in recent years, according to SIPRI.

China has also rapidly increased its nuclear stockpile, SIPRI said, with the G7 raising the alarm Friday over Moscow and Beijing boosting their nuclear capabilities.

US President Donald Trump has indicated his intention to conduct new nuclear tests because “other countries are doing it too.”

In March, France’s President Emmanuel Macron announced a dramatic shift in nuclear deterrence, notably an increase in the atomic arsenal, currently numbering 290 warheads.



– NPT could ‘unravel’ –



“It is obvious that trust is eroding, both inside and outside the NPT,” Seth Sheldon of the International Campaign to Abolish Nuclear Weapons (ICAN), a Nobel Peace Prize laureate, told AFP.

He questioned the likely outcome of the four-week summit.

Decisions on the NPT have to be agreed by consensus, with the previous two conferences failing to adopt final political declarations.

In 2015, the deadlock was largely due to opposition by Israel’s arch-ally Washington to the creation of a nuclear-weapon-free zone in the Middle East.

In 2022, the impasse was due mainly to Russian opposition to references to Ukraine’s nuclear power plant at Zaporizhzhia, occupied by Moscow.

This year’s summit could fall on any number of stumbling blocks.

The ongoing war in Ukraine, Iran’s nuclear program and the war there, non-nuclear states’ fears over proliferation and North Korea’s developing arsenal could all be deal-breakers.

If there is a third consecutive failure, the treaty “might not implode overnight” said Christopher King, the conference’s secretary-general.

But there is a risk “it will, over time, unravel.”

Artificial intelligence could be a prominent issue as some countries call for all sides to keep human control over nuclear weapons.

From sun to subsoil, how countries are moving away from fossil fuels

Plant waste is turned into briquettes of biochar, or "green coal", in Chad

Heating with geothermal energy, lighting with solar panels, cooking with biodegradable waste: how can we live with less oil and gas?

It’s a long-burning question — but one that is catching fire as energy costs soar due to the conflict in the Middle East, which has strangled exports of crude oil and liquefied natural gas (LNG).

With the global energy shock caused by the conflict expected to linger, AFP’s video journalists around the world have explored how countries are experimenting with the climate transition.

– Geothermal in France –

For a long time, the owners of the building where Anne Chatelain lives near Paris resisted switching from gas heating to geothermal energy.

But on January 1 they finally began heating their homes using the natural heat from the subsoil — the soil immediately beneath the surface.

As energy bills soar elsewhere in the world, “Our property manager has announced a 20 percent reduction in heating and hot water bills for 2026 and 2027,” rejoices the 69-year-old retiree.

The tech is both climate-friendly and, as a local resource, “not subject to taxation and geopolitical upheavals” such as the war with Iran, says Gregory Mascarau, a Paris director for the French multinational electric utility company ENGIE.

Shallow geothermal energy allows for heating and cooling by using the temperature of the subsoil at depths of less than 200 meters (650 feet).

Deep geothermal energy involves extracting hot water from depths of 1,000 to 2,000 metres, where its temperature ranges from 80C to 150C.

Since 2023 it has resulted in roughly 25-30 percent savings compared to the cost of heat provided by fossils fuels, says Ludovic Feron, head of the real estate infrastructure department at Gustave Eiffel University.

The catch is that a suitable subsoil is required, and that deep geothermal energy in particular can be hampered by high costs and uncertainties.

In France, this type of heating represents only about one percent of final heat consumption — for now.

– ‘Green coal’ in Chad –

It looks like charcoal, but the black briquettes are actually made from plant waste: millet and sesame stalks, palm fronds and cobs.

The residues are sorted, ground and mixed with a maceration of gum arabic to facilitate ignition, and with clay to slow combustion.

“It doesn’t smoke, it lasts, and it’s economical. And I can see that it doesn’t blacken the pot, and there aren’t even any side effects,” says Sophie Saboura, 24, a resident of the Chadian capital N’Djamena.

The briquettes last up to three times longer than traditional charcoal, according to Ousmane Alhadj Oumarou, technical director of the Raikina Association for Socio-Economic Development (Adser) factory.

“From an environmental standpoint, eco-friendly charcoal contributes to sanitation. And it also reduces the effects of climate change. It also helps combat deforestation,” says Oumarou.

Adser produces about 10 tonnes of briquettes, used for cooking, every day — but they aren’t available everywhere.

“There are limits to its use. Because even the manufacturing process takes time … it can take a week,” says Pierre Garba, a renewable energy specialist.

“Sometimes, when there’s demand, you try calling, you wait, and wait, and wait,” confirms Saboura.

– Solar in Pakistan –

The aerial view of Islamabad is striking: solar panels stretch as far as the eye can see from the rooftops of the lush, green Pakistani capital.

Pakistan’s shift to solar power is “one of the fastest consumer-led energy transitions on record”, according to a recent study by a Pakistani think tank.

Unlike Western economies, Pakistan — whose citizens have long struggled with energy shortages, blackouts and regular loadshedding — did not impose tariffs on solar technology from neighbouring China from 2013 to 2025.

The rise in oil and gas prices following Russia’s invasion of Ukraine in February 2022 has also spurred consumers to embrace solar power.

Imports have surged from one gigawatt in 2018 to 51 gigawatts this year.

In the bustling streets of the ancient Mughal city of Lahore, Pakistan’s cultural capital, 49-year-old shopkeeper Aftab Ahmed is looking for solar panels to install at his home.

“It has become so expensive that an average person can no longer afford fuel for a motorcycle or a car. Fuel prices are also affecting electricity bills, leading to further increases,” he says.

Solar power offers the possibility of “at least some savings”.

Is a mysterious ‘fifth force’ hiding out in the depths our solar system?

Astronomers are grappling with a cosmic mystery: Why does the Universe behave differently on massive scales compared to our own solar system?

While distant galaxies reveal clear signs of something bending the rules of gravity—often attributed to dark energy or a hidden “fifth force”—everything nearby seems to follow Einstein’s playbook perfectly.

A force refers to an action that can cause an object to change its velocity or its shape, or to resist other forces, or to cause changes of pressure.

Dark energy and dark matter are among the most difficult concepts to test. Observations across vast regions of space clearly suggest that something is influencing gravity in ways Einstein’s theory does not fully explain. Yet within our own solar system, everything appears to behave exactly as expected.

Dark matter and dark energy are invisible components of the universe: dark matter pulls matter together through gravity, while dark energy drives the universe’s accelerated expansion.

A new study by Slava Turyshev, a physicist at NASA’s Jet Propulsion Laboratory, explores how researchers might address this mismatch. His work suggests that the key may lie in being extremely precise and selective in how experiments are designed to search for signs of dark energy and dark matter closer to home.

The Great Disconnect

At the centre of the problem is what scientists call the “Great Disconnect.” The laws of physics seem to operate differently depending on the scale being observed. In regions with very little matter (i.e. no gravitational force), the effects linked to dark energy or modified gravity become much more noticeable. In contrast, in dense environments filled with matter and strong gravity, those same effects seem to vanish, at least based on current instruments.

Within the solar system, everything aligns with traditional physics. Planets follow their expected orbits. Measurements of spacetime around the Sun, including data from spacecraft signals, match predictions precisely. Every probe sent through the solar system behaves as if only standard gravity is at work. There are no clear signs of anything unusual.

New perspectives

The situation changes when looking far beyond our ‘local neighbourhood’. On the scale of galaxies and beyond, the Universe appears to be expanding. While scientists continue to debate the exact rate of this expansion, there is strong evidence that something is influencing gravity or spacetime in ways not fully captured by current theories.

At present, dark energy is the best explanation for this behavior, even though its true nature remains unknown.

The universe is expanding due to dark energy, a mysterious force that drives this acceleration, making up about 68% of the universe.

One possible explanation involves a phenomenon known as “screening.” In this idea, whatever is causing the discrepancy changes how it behaves depending on the surrounding environment. As density increases, its effects become weaker or harder to detect.

Screening models

There are two main types of screening models. The first is called the “chameleon” model. In this scenario, a hypothetical fifth force of nature (other than gravity, electromagnetism, and the two nuclear forces) adjusts its strength based on the amount of nearby matter.

In low density regions, it becomes strong and produces effects associated with dark energy. In dense areas, it weakens so much that current instruments cannot detect it, even though it still exists. Around objects like the Sun, it might only appear in a thin outer layer, but in principle it could still be measured there.

Vainshtein Screening

Another explanation is the Vainshtein screening model. Arkady Vainshtein (born 24 February 1942) is a Russian-American theoretical physicist recognized for his contributions to particle physics.

Here, the force itself does not change. Instead, the surrounding gravity effectively suppresses its influence, making it appear weak. The model introduces the concept of a Vainshtein Radius, which marks the distance where the force regains its normal strength.

The Vainshtein screening model is a mechanism that suppresses extra gravitational forces near massive objects through derivative self-interactions in modified gravity theories. It operates in scalar-tensor systems where the action includes higher-derivative nonlinearities of the scalar field.

For the Sun, this radius is estimated to extend about 400 light years. That region includes many stars, meaning the force would remain suppressed well beyond the solar system and even across large parts of the galaxy.

Why New Solar System Missions May Be Needed

Both screening models could leave subtle traces in large-scale observations collected by missions such as Euclid and The Dark Energy Spectroscopic Instrument (DESI). However, these surveys focus on distant galaxies and cannot directly reveal how such forces behave within the solar system.

To test these ideas locally, scientists would need a dedicated mission designed specifically for that purpose. Even more important, researchers would need a falsifiable theory that predicts what such a mission should detect.

Next steps

It may take time to develop instruments sensitive enough to detect these subtle effects. In the meantime, incremental progress will be important, with missions focused on improving measurement capabilities step by step.

If a well-defined and testable prediction emerges from current data, and if an experiment can realistically be built to test it, pursuing that opportunity could lead to a major breakthrough. Such a discovery has the potential to reshape our understanding of gravity, dark energy, and the fundamental workings of the Universe.
Research paper

The findings appear in the journal Physical Review D. The research paper is titled “Solar-System experiments in the search for dark energy and dark matter.”

Why Gulf Countries Want Ukrainian War Know-How – Analysis

April 26, 2026 
EurActiv
By Miriam Saenz de Tejada

(EurActiv) — Ihor Fedirko, CEO of the Ukrainian Council of Defence Industry, an organisation representing the country’s armaments sector, is happy just to be alive.

“We are all alive, so it’s okay”, he told Euractiv, responding to questions about how he’s doing. It was a disarmingly simple answer, and yet it was representative of the atmosphere in Ukraine’s defence industry. Production lines run amid air-raid sirens, and engineers redesign systems that are used mere hours later.

It is amidst this reality that Volodymyr Zelenskyy, Ukraine’s President last week announced a series of defence agreements with Gulf countries, including Saudi Arabia, the United Arab Emirates and Qatar. He presented them not as conventional arms deals but as the export of full-spectrum capabilities under a so-called “drone deal” that’s officially transformed Ukraine into a global arms exporter.

The announcement marks a turning point. Ukraine is no longer just a recipient of Western military aid. It’s becoming a provider of war-tested expertise to other countries facing similar threats.


For Gulf countries recently hit by Iranian drones and missiles, the appeal is immediate. For Europe, the implications, as seen from Brussels and beyond, are more complex.
The Gulf states: an urgent matter

At first glance, the deals appear to centre on drones, especially interceptor systems designed to stop Iranian threats. But Fedirko insists that reading misses the point.

“We told them… the interceptor is just one piece of this picture”, the CEO said, describing talks with Gulf partners.

What Kyiv is exporting is not a product per se but an ecosystem. Years of countering Shahed-type drones – and increasingly sophisticated Russian variants – forced Ukraine to constantly adapt its air defence. John Hardy, deputy director of the Foundation for Defense of Democracies (FDD)’s Russia program, noted that Russian air threats evolved, becoming harder to jam and deploy at scale, pushing Kyiv to respond just as quickly.

The result is a layered network combining sensors, software, interceptor drones and mobile fire units. It is less a single shield and more of a constantly adjusting web.




It is also cheaper. Ukraine learned early that using expensive missiles against low-cost drones is unsustainable. Gulf states facing similar threats are now looking for the same answer: wider coverage at a lower cost.

However, direct replication is difficult. Ukraine’s large territory allows threats to be tracked over a distance, while smaller Gulf states operate in tighter airspace, Hardy noted. Systems, therefore, require adaptation, not duplication.

That is why the agreements go beyond hardware. They oversee training, the integration of these new systems into the country’s military combat guidelines, and co-production. In many Gulf markets, localisation laws require significant domestic manufacturing, meaning Ukrainian firms must build locally rather than merely export finished systems.
Europe: watching closely, moving slowly

While Gulf states move quickly, Europe’s response is more cautious.

Ukraine’s progress in drones, electronic warfare and rapid manufacturing has become increasingly relevant as the EU seeks to build its drone arsenal and expand defence production.

But Fedirko argues Europe still faces a structural gap. “They still don’t adapt their drones into their military doctrines,” the CEO said.

The criticism goes beyond drones. Ukraine’s wartime systems rely on tight links between battlefield units, engineers and manufacturers, allowing rapid redesign and deployment. Europe, by contrast, remains bound by slower procurement cycles and fragmented national systems.

“Your weakness is around your velocity,” he added.

Still, Europe offers what Gulf states cannot: scale. Financing, industrial depth and long-term demand make the continent a crucial future market for Ukrainian firms, particularly through joint production.
A new defence exporter

Zelenskyy’s Gulf announcement reflects a wider shift. In just a few years, Ukraine has moved from defence dependency to being a competitive defence supplier.

More than 80 co-production agreements have already been signed worldwide, according to the Ukrainian Council of Defence Industry.

What partners in the Gulf, and increasingly in Europe, are buying is not just equipment. It’s experience under literal fire, compressed into systems that work and are adaptable to partners.

And in a world where threats evolve faster than the technologies to stop them, that may be Ukraine’s most valuable export.

Like something straight out of a spy movie, lots of cloak and dagger was required before AFP could meet three Ukrainian drone manufacturers on the fringes of a hush-hush defence forum in Paris earlier this month.

A rendezvous was set up on a bench near the Champs-Elysees, and a hint of Russian being spoken nearby prompted a quick change of hotel lounge at another interview.

The expertise Ukraine has honed with machines that have transformed the battlefield and left European armies trailing in their technological wake, is highly sought after, with their impact proved again in the Middle East war.

“When I talk to Europeans or Americans, they know very little” about these drones, said Olexandr, an engineer producing Ukraine’s “largest strike drone”, the Perun Max.

“We want to see how countries that have supported us, such as France, can benefit from our experience,” he added.

Made at secret locations across Ukraine by Bavovna, the Perun Max can carry “three projectiles, drop them on targets, return, reload and take off again,” making up to 30 sorties a night, he said.

The drone can transport loads of 32 kilos over 25 kilometres (15 miles) — food, water and medicine for soldiers in the trenches — or leaflets telling people “how to surrender properly and stay alive” in areas where the Russians are advancing.

Bavovna makes 1,000 drones per month, costing between 7,000 and 20,000 euros.

And the system can switch from GPS to optical navigation, flying with the antenna cut off for up to 20 kilometres.

– Two battalions ‘neutralised’ –

Skyfall — whose name is a nod to the Bond film — also began life when Russia invaded in 2022 and four engineers met up in a garage to build a drone capable of monitoring activity over Kyiv.

They soon decided to add a “dropping” capability, creating Vampire, which bombs, lays mines remotely and transports blood or generators.

Vampire reportedly took part in NATO exercises in May 2025 in Estonia, during which 10 Ukrainian drone operators “neutralised” 17 armoured vehicles and two enemy battalions, the Wall Street Journal said.

The “drone sky” renders the battlefield transparent, where men and armoured vehicles become targets as soon as they venture into no man’s land, French military officials and experts said.

“A French unit deployed today on the Ukrainian front against the Russian army would get thoroughly hammered. We must follow the Ukrainian army’s example if we want to stay in the game,” said Colonel Michel Goya, a former French marine officer and modern conflict analyst.

France is set to reassign 5,000 of 77,000 ground force troops to drone-related activities.

Faced with mass-produced products which are “designed to wear down our capabilities… we need systems which are just as massive, inexpensive, and easy to produce,” said General Bruno Baratz, hinting some in the French military hierarchy are reluctant to make the leap.

Bastien Mancini, CEO of French drone manufacturer Delair set up a firm in Ukraine and now supplies drones to the French military.

“Three years ago our drones were being shot down by Russian missiles that cost much more; today they are being shot down by much cheaper systems,” he told AFP.

– ‘Intelligent machine gun’ –

Shrike, another small FPV drone from Skyfall piloted via an onboard camera, costs just $500. Its makers boast it was the first to “shoot down a $10 million (Russian) Mi-8 helicopter in mid-flight.”

“These drones have destroyed enemy equipment worth several billion. We can produce over a million of them a year,” a Skyfall spokesman claimed.

A third model, the P1-Sun interceptor nicknamed Pisiun (penis), “has already destroyed some 2,500 (Iranian-designed) Shaheds and 1,500 other aerial targets,” he added.

“The priority remains the defence of Ukraine,” he insisted, which is why Kyiv must approve any international link-ups.

But “it would be good if the whole world saw that Ukrainian solutions don’t just work in Ukraine.”

The Khyzhak (Predator) system, equipped with a 7.62 mm machine gun, was first developed by Ukraine’s UGV Robotics for the Magura naval surface drones which have sunk or damaged several Russian warships in the Black Sea.

The idea of “turning a simple machine gun into a smart weapon” has now been extended to shooting down drones in flight,” said Dmytro Burakov of UGV.

“We’ve installed the system on Mi-8 and Airbus helicopters and that’s how we’re now shooting down Shaheds,” he said.

After talking to AFP, he rushed off to a meeting with Airbus Helicopters, who are developing their own more sophisticated drones, with some 30 planned for this year and twice that number by 2027.

The CEO of German tank giant Rheinmetall sparked a row last month by taking a pop at Kyiv’s drones, saying they were being made by “Ukrainian housewives” — though Armin Papperger later walked back the remarks.

“If Ukrainian drones made by housewives are destroying tanks, then the era of housewives is here,” quipped the Skyfall spokesman, further proof of how the old defence industry is rattled.

Tesla’s much-touted autonomous “robotaxi”, called the Cybercab, has started production, CEO Elon Musk said on Friday, a day after the carmaker reported first-quarter profits that beat expectations.

Musk posted a promotional video on X accompanied with the brief caption, “Cybercab has started production.”

The 38-second clip, mostly shot from within a driverless Cybercab, showed the vehicle rolling off the factory floor and driving onto streets.

Musk also shared a short video clip showing what appeared to be multiple gold-colored Cybercabs driving in formation on a road.

Tesla said on Wednesday it was on track to commence “volume production” of both its Cybercab and Tesla Semi this year, after reporting first-quarter profits of $477 million.

Cybercab — billed as a self-driving robotaxi without a steering wheel or pedals — was first unveiled in the fall of 2024, with Musk predicting at the time that it would become available in 2027.

Tesla began offering robotaxi services to “early access” users on an invitation-only basis in the US city of Austin, Texas, last June.

The auto manufacturer posted a photo in February showing employees gathered around a Cybercab on a factory floor, with the caption “First Cybercab off the production line at Giga Texas.”

Self-driving cars will ‘not fix’ urban parking problem

The global AI transportation market is expected to grow from USD $2.12 billion in 2023 to USD $10.25 billion by 2033, at a Compound Annual Growth Rate (CAGR) of 17.07%.

Self-driving cars, among various accolades, are supposed to fix urban parking. Shared autonomous fleets could drop passengers and relocate, freeing high-value city land for housing, parks, and commercial use. Although this is not something that can be achieved now, the long-run case has a degree of coherence about it. Nonetheless, the short-run story is the opposite, and it is not being adequately covered.

In the transition period, before shared autonomous vehicles (AVs) reach critical mass, autonomous vehicles cruising between drop-offs without parking add traffic volume without reducing the number of cars seeking spaces. A 2024 peer-reviewed study found that parking demand structures shift in ways that create new friction before they ease it. The fix arrives late. The disruption arrives first.

For example, in Manhattan alone, a single parking space costs up to $6,000 to build, with the U.S. parking industry generating $21 billion in 2022.

By 2030 it is estimated there will be 39 million AVs on the road. With this prediction, study data suggests:

Automation could also save up to 90% on vehicle insurance premiums.

Autonomous vehicle testing has already decreased the number of accidents across the United States from 9.1 per million miles to 4.6 per million miles.

About 25% of fatal car accidents result from the speed at which cars travel, and this should be better regulated with self-driving cars.

By 2050, self-driving cars could save around 21,700 lives and prevent about 4.22 million accidents every year.

Automation could lead to an 80% reduction in traffic-related problems.

Automation could reduce car emissions by up to 90%.

Also, nothing is likely in the short-term, full US fleet automation is not projected before 2045, meaning large-scale parking relief is at minimum two decades away

A new strategy is needed, and this leads to a new study proposal. To achieve real parking reductions, AVs must be shared, pooled, metro-wide, and paired with high-capacity public transit. Remove any one condition and the reduction shrinks to near zero

Why the Conditions Are Hard to Meet

Research from the University of Oregon identified four requirements for AVs to meaningfully cut urban parking demand. Vehicles must be shared, not privately owned. Riders must pool trips. Deployment must cover entire metro areas. And AVs must work alongside, not instead of, public transit. Current deployments meet none of those conditions at scale. Most autonomous vehicles sold today are privately owned and park exactly where their human-driven predecessors did.

The global smart parking market is projected to grow from $5.5 billion in 2023 to $8.3 billion by 2033, in part driven by AV integration. The cities best placed to benefit are those building shared mobility infrastructure now. Most are not.
