Businesses can begin filing for tariff refunds on Monday as the federal government starts unwinding billions of dollars in import duties imposed by the Trump administration under emergency powers, opening the door to what could be one of the largest repayments to importers in U.S. history.

At 8 p.m. ET on April 20, U.S. Customs and Border Protection (CBP) will launch the first phase of a new claims system that will allow importers to seek repayment of tariffs collected under the International Emergency Economic Powers Act (IEEPA), following a series of court rulings that invalidated the policy.

The Supreme Court ruled in February that the law President Donald Trump relied on for his signature policy did not authorize the imposition of tariffs, finding that Congress – not the president – holds authority over such taxes. The decision set the stage for lower courts to order the government to reverse course and return the funds.

A judge at the U.S. Court of International Trade subsequently directed CBP to remove the tariffs from affected entries and refund any excess duties collected, along with interest.

The scale of the refunds could be significant for businesses across industries. Court filings show more than 330,000 importers paid duties on over 53 million shipments, totaling roughly $166 billion.

Starting Monday, companies and their customs brokers can submit refund requests through CBP’s Automated Commercial Environment (ACE) portal using a newly developed tool known as the Consolidated Administration and Processing of Entries, or CAPE.

The system allows importers to file declarations listing the entries for which they are seeking refunds. Once a claim is validated, CBP will recalculate the duties without the IEEPA tariffs and reliquidate the entries, triggering repayment.

CBP said valid refunds will generally be issued within 60 to 90 days after a claim is accepted, though more complex cases could take longer. The agency is rolling out the process in phases, with the initial stage limited to certain unliquidated entries and those within 80 days of final accounting.

Officials have warned the process could be complicated given the scale. In court filings, CBP described the volume of refunds as “unprecedented,” noting that existing systems were not designed to handle so many claims and may require significant manual processing.

The refunds will be paid directly to the businesses that originally paid the tariffs, marking an early step in reversing a major trade policy with broad economic impact.

SANTA BARBARA, California — Nobel Prize-winning physicist David Gross has issued a stark warning that humanity stands a slim chance of surviving another 50 years, citing the grave risk of nuclear war as the primary barrier preventing scientists from achieving a unified theory of all fundamental forces.

Gross, who shared the 2004 Nobel Prize in Physics for his work on the strong nuclear force and asymptotic freedom, made the comments in a recent interview with Live Science while discussing the long quest for a “theory of everything” that would reconcile quantum mechanics with gravity. When asked whether physicists might complete such a unification within 50 years, the 83-year-old researcher replied bluntly that the chances of humanity lasting that long are “very small.”

“Currently, I spend part of my time trying to tell people … that the chances of you living 50 [more] years are very small,” Gross said. He pointed specifically to nuclear war as a potential civilization-ending catastrophe that could arrive within 35 years, emphasizing that geopolitical tensions and the persistence of thousands of warheads worldwide make the threat immediate and existential.

The remarks, which quickly spread across scientific and popular media outlets, highlight a growing pessimism among some leading thinkers about humanity’s long-term prospects amid multiple overlapping risks. Gross, who also received the $3 million Special Breakthrough Prize in Fundamental Physics, has devoted decades to string theory and efforts to unify the four fundamental forces — gravity, electromagnetism, and the strong and weak nuclear forces. Yet he now sees human self-destruction, rather than scientific obstacles, as the greatest hurdle.

Nuclear war remains a central concern. With Russia’s ongoing conflict in Ukraine, tensions over Taiwan, and the proliferation risks involving nations such as North Korea and Iran, the probability of escalation to nuclear exchange has drawn renewed attention. Gross suggested that without dramatic progress in arms control and diplomacy, civilization could collapse long before physicists resolve the deep mathematical and conceptual challenges of quantum gravity.

His comments echo broader warnings from other Nobel laureates and scientists. Geoffrey Hinton, often called the “godfather of AI” and a 2024 Nobel Prize winner in Physics for foundational work on neural networks, has raised the odds of artificial intelligence causing human extinction to 10-20 percent within the next 30 years. Michel Mayor, the 2019 Nobel laureate who discovered the first exoplanet orbiting a sun-like star, has stated that humanity is not eternal but simply another animal species destined for extinction, potentially within a million years from natural causes alone, and far sooner if human folly intervenes.

Gross’s perspective stands out for its focus on the intersection of fundamental physics and human survival. A unified theory has eluded physicists since Einstein’s unsuccessful attempts at a unified field theory. String theory, loop quantum gravity and other approaches offer promising frameworks, but experimental verification remains extraordinarily difficult because the energies required to probe quantum gravity effects are far beyond current particle accelerators. Gross noted that even optimistic timelines for theoretical breakthroughs could be rendered moot by humanity’s inability to avoid catastrophe.

The physicist did not dismiss all hope. He expressed a desire for international cooperation to reduce nuclear arsenals and mitigate other existential risks, including climate change, pandemics and uncontrolled artificial intelligence. “If you don’t [address these risks], there’s always some risk an AI 100 years from now [could launch nuclear weapons],” he observed, underscoring how multiple threats compound one another.

Public reaction to Gross’s interview has been swift and polarized. On social media platforms and science forums, some users praised the laureate for speaking candidly about uncomfortable truths, arguing that complacency about existential risks has become dangerous. Others criticized the comments as overly alarmist or defeatist, suggesting they could undermine efforts to solve pressing problems by fostering fatalism. Science communicators noted that such warnings from respected figures often serve to galvanize action rather than induce despair.

Experts in existential risk studies have long catalogued the threats Gross referenced. The Bulletin of the Atomic Scientists maintains its Doomsday Clock, which in recent years has stood close to midnight due to nuclear dangers, climate disruption and emerging technologies. Organizations such as the Future of Humanity Institute and the Centre for the Study of Existential Risk at Cambridge University have modeled scenarios in which nuclear winter, engineered pandemics or misaligned superintelligent AI could lead to human extinction or civilizational collapse.

Gross’s career lends weight to his assessment. As a towering figure in theoretical physics, he has witnessed firsthand how scientific progress depends on stable societies capable of sustaining long-term research. Particle physics collaborations such as those at CERN involve thousands of scientists across dozens of nations and require decades of funding and political support. A major war or societal breakdown could shatter that infrastructure, halting progress indefinitely.

Yet the quest for unification continues. Researchers are exploring connections between string theory and holography, advances in quantum computing that might simulate quantum gravity effects, and new observational windows through gravitational wave astronomy and cosmic microwave background studies. Gross himself remains active in the field, though he now balances theoretical work with public advocacy for risk reduction.

The broader context includes accelerating technological change. Artificial intelligence is transforming scientific discovery, potentially speeding up theoretical breakthroughs while simultaneously introducing new dangers. Climate models warn of tipping points that could render large parts of the planet uninhabitable within decades. Biodiversity loss and resource depletion compound these pressures.

Gross stopped short of predicting exact timelines or probabilities beyond his qualitative assessment, but his message was clear: humanity’s greatest obstacle to scientific immortality may be its own mortality as a species. He urged greater investment in diplomacy, arms control, sustainable development and ethical governance of emerging technologies.

For physicists dreaming of a final theory that explains the universe from the smallest scales to the largest, the warning carries particular poignancy. The unification of forces has been called the holy grail of physics. Achieving it would represent one of humanity’s crowning intellectual achievements, potentially unlocking new technologies and deeper understanding of reality itself. Gross suggested that realizing that dream may depend less on brilliant equations than on collective wisdom and restraint.

As the interview circulates widely, it joins a chorus of voices from the scientific community urging humanity to confront its fragility. Whether Gross’s pessimism proves prophetic or serves as a catalyst for renewed global cooperation remains to be seen. For now, his words stand as a sobering reminder that the biggest questions in physics may ultimately hinge on the oldest challenge facing humankind: learning to live together without destroying ourselves.

In laboratories and lecture halls around the world, researchers continue their work, driven by curiosity and the hope that humanity will endure long enough to glimpse the deepest secrets of the cosmos. Gross’s warning challenges them — and all of society — to ensure that hope is justified.

The Somerset-based company has seen a rise in retail and online sales across all regions and markets

Luxury Somerset handbag maker Mulberry has declared the turnaround at the group is “firmly under way” as it returned to sales growth across all markets. The Chilcompton-based group said UK retail and online like-for-like sales jumped 13.7 per cent higher in its final six months, up from 6.5 per cent growth in the third quarter.

Overall group comparable sales rose 12.8 per cent in the second half to March 28, or 13.6 per cent higher with currency effects stripped out, with growth across all regions and markets. It marks a sharp reversal of trading fortunes, after group sales dropped 3.2 per cent on a constant currency basis in the firm’s first half.

Chief executive Andrea Baldo said it had been “a year of decisive progress”.

He said: “Despite a challenging economic and geopolitical environment, we have delivered growth across all channels and geographies, with clear momentum right across the business.

“This performance reflects the disciplined execution of our ‘Back to the Mulberry Spirit’ strategy, and demonstrates that our turnaround is firmly under way.”

The company launched a turnaround of the business in late 2024, which saw 85 jobs axed – around a quarter of its head office staff.

It also raised £20m in June last year to help bolster its transformation, after turnover slumped 21 per cent in 2024. In November, it was revealed the company had cut its losses by more than half.

The group’s back-to-basics strategy has seen it move away from discounting and concentrate on “tighter, more focused” ranges and improved availability.

“We are simplifying the business, restoring full price discipline, strengthening our connection with customers, and reasserting Mulberry’s position as a distinctive British lifestyle brand,” Mr Baldo said.

Its new approach saw its Bayswater Limited Edition bag sell ⁠out within minutes of its launch in February, according to the group.

In March, the business announced it had appointed Scottish designer Christopher Kane as new creative director. He will be responsible for relaunching Mulberry’s women’s ready-to-wear collection, with the debut expected to take place at London Fashion Week in September.

The group’s second-half performance has left it with overall annual sales growth of 5.7 per cent on a constant currency basis.

KUWAIT CITY — Kuwait International Airport did not reopen to commercial passenger flights on Monday, April 20, 2026, as officials continued safety assessments and infrastructure repairs following damage from drone strikes linked to regional conflict, with no confirmed resumption date announced despite a high-level government inspection the previous day.

The Directorate General of Civil Aviation and state media reiterated that the airport, closed since February 28 after sustaining hits to Terminal 1, radar systems and fuel storage facilities, remains shut to all scheduled arrivals and departures. Flight tracking platforms and the official airport website showed blank boards with no commercial movements, while departure and arrival information pages displayed messages indicating no scheduled flights.

Prime Minister Sheikh Ahmad Abdullah Al-Ahmad Al-Sabah visited the airport on Sunday, April 19, accompanied by the defense minister and the president of the Public Authority for Civil Aviation. State news agency KUNA reported the tour focused on reviewing reopening plans, evaluating safety measures and ensuring readiness for operations in line with approved standards. The prime minister stressed the need for full compliance with international aviation requirements before any resumption, but stopped short of setting a timeline.

Authorities have repeatedly denied circulating rumors of an imminent reopening, including unverified social media claims suggesting operations could resume as early as April 20 or that Terminal 5 used by Jazeera Airways might restart service. The Civil Aviation Authority issued statements urging the public to rely solely on official channels and avoid spreading unconfirmed information that could confuse travelers and businesses.

The prolonged closure, now stretching beyond seven weeks, stems from a series of drone attacks that damaged critical infrastructure during heightened tensions in the broader US-Israel-Iran conflict. Initial strikes in late February targeted Terminal 1, causing minor injuries to several employees but no fatalities. Subsequent attacks in March severely impaired the airport’s radar systems, complicating safe navigation and air traffic control. Fuel depots also sustained damage, raising concerns over supply reliability for any potential flights.

Kuwait Airways and Jazeera Airways have redirected operations primarily through King Fahd International Airport in Dammam, Saudi Arabia, with ground transfers arranged for passengers via the Nuwaiseeb border crossing. Some routes, including to Manila and Cairo, have resumed via this alternative hub, but the arrangement adds time, cost and logistical complexity for travelers. International carriers have similarly rerouted or canceled services, affecting connections to Europe, Asia and beyond.

The situation has created significant challenges for Kuwait’s economy and residents. Thousands of expatriate workers, business travelers and families have faced disrupted plans, with many opting for indirect routes through Dubai, Doha or Bahrain. Hotels and tourism operators reported reduced activity, while freight forwarders noted delays in goods movement, particularly for time-sensitive items like pharmaceuticals and perishable foods. Australians and other international travelers have been advised to reroute entirely, as the closure continues to strain alternative Gulf hubs.

Aviation experts estimate that full repairs to radar equipment, fuel infrastructure and terminal facilities could require several more weeks, potentially pushing a gradual reopening to late May or early June, subject to rigorous safety certifications and regional airspace stabilization. Procurement of replacement radar systems from international suppliers may add further delays. While a fragile US-Iran ceasefire announced in early April offered some hope for de-escalation, it has not yet translated into restored operations at Kuwait International Airport, which remains the only major Gulf hub without commercial flights.

Travelers holding bookings are encouraged to contact their airlines directly for rebooking options or refunds. Kuwait Airways has maintained flexibility on affected tickets, but the lack of a firm reopening date leaves many in limbo, especially those with urgent medical, business or family commitments. The airport’s inquiry hotline continues to direct callers to airline contacts rather than providing specific resumption information.

The government’s focus during the prime ministerial visit underscored a cautious approach prioritizing safety over speed. Officials highlighted the importance of supporting air transport while ensuring full readiness, including enhanced security protocols and coordination with international bodies. Any phased reopening would likely begin with limited flights and expand gradually after successful test operations and certifications.

For now, the message from authorities remains consistent: Kuwait International Airport is not open for commercial operations as of April 20. Rumors of a sudden restart, including speculative YouTube videos and social media posts claiming flights could resume immediately with dropping fares, have been firmly debunked. The Civil Aviation Authority has warned that premature announcements create unnecessary confusion and potential hardship for passengers making alternative arrangements.

The closure highlights vulnerabilities in regional aviation amid geopolitical tensions. Kuwait’s proximity to conflict zones and reliance on advanced radar and fuel systems made it particularly susceptible to disruptions. Since the initial strikes, limited military or special flights may have operated under restricted protocols, but these do not include civilian passenger services.

As repairs progress, neighboring airports have absorbed increased traffic, creating both opportunities and capacity strains. Dammam has seen a surge in Kuwaiti-linked flights, while carriers adjust schedules to accommodate rerouted passengers. Ground transport between Saudi Arabia and Kuwait has become a critical lifeline, though border procedures add another layer of complexity.

The economic ripple effects extend to sectors dependent on seamless connectivity, including oil and gas operations, construction projects and retail reliant on international supply chains. Expatriate communities, which form a large portion of Kuwait’s workforce, have expressed frustration over prolonged separations from family members abroad.

Looking ahead, the government is expected to provide regular updates through official channels as milestones in the repair and certification process are reached. A successful reopening would mark an important step toward normalizing life in Kuwait and restoring its role as a regional aviation connector. In the meantime, patience and proactive planning remain essential for anyone affected by the ongoing suspension.

The situation continues to evolve alongside broader diplomatic efforts to stabilize the region. A durable ceasefire and improved security environment could accelerate timelines, but officials maintain that infrastructure integrity and international safety standards will dictate the pace. For travelers checking status on April 20, the reality is unchanged: departure boards remain empty, and commercial flights stay suspended until further notice.

Kuwait International Airport’s extended closure serves as a reminder of how quickly geopolitical events can impact civilian infrastructure. As preparations advance following the prime minister’s inspection, residents and international partners await the moment when the skies over Kuwait reopen safely, reconnecting the nation to the global travel network.

Until that announcement comes through verified channels, travelers should monitor airline communications and explore viable alternatives to minimize disruption. The commitment to safety expressed during Sunday’s high-level visit suggests authorities will not compromise on thoroughness, even as pressure builds for a swift return to normal operations.

A new report from the Energy and Climate Intelligence Unit says Wales’ pipeline for renewables is less developed than in England and Scotland

Wales is no longer a net exporter of electricity and unless it addresses a stalling in renewable projects is at risk of becoming more dependent on imported gas and electricity from England, a new analysis has found.

New research from the not-for-profit Energy and Climate Intelligence Unit (ECIU) comes as the conflict in the Middle East has sent gas prices soaring to a three-year high with independent analysts Cornwall Insight estimating that the average household energy bill could rise by nearly £300 when the energy price cap is revised in July.

The Welsh Government has set a target of meeting 100% of its electricity demand from renewable sources by 2035. The report shows that renewable generation has grown nearly eightfold since 2024 in Wales and now meets around a third of Welsh electricity demand.

However, it highlights that growth has stalled since 2019 and experts have warned that Wales’s renewables planning pipeline, although still substantial, is smaller and less developed than in England and Scotland. Wales has lost its status as being a net electricity exporter – down from a peak of over 21 TWh (terawatt hour) in 2016 to near zero in 2024. Last year Wales was a net importer from England for the first time.

The ECUI report also shows that electricity generation has fallen by almost 50% from its 2016 peak, as growth in renewable capacity has not kept pace with the drop in generation from coal and nuclear. Gas now accounts for 58% of Welsh generation – a greater share than any other UK nation – leaving Welsh generators and their downstream customers across the UK heavily exposed to volatile international fossil fuel markets.

This recent slow progress in scaling up renewables capacity, coupled with a rising demand for electricity, which is forecast to double by 2050, means that renewables’ share of generation is currently forecast to fall, according to ECIU projections. This risks leaving Wales more dependent on gas generation, which already accounts for 58% of Wales’s power output – more than any other nation in the UK.

In the UK, the cost of gas dictates domestic electricity prices the vast majority (85%) of the time. As the price of gas is itself largely set by international markets, the ECIU said this leaves British consumers acutely vulnerable to global price shocks – with the IMF warning that the UK will be “especially exposed” to the fallout from the war in Iran as a result of its dependence on gas-powered generation.

The report says that accelerating the deployment of new renewables is essential to squeezing gas off the grid and shielding consumers from volatility in international markets – a position supported by organisations such as the International Energy Agency and Energy Crisis Commission.

Laura Dunn, senior associate at the ECIU, said: “The cost-of-living is voters’ number one priority heading into the Senedd elections, with growing fears of a repeat of the energy crisis which followed the Russian invasion of Ukraine. In an increasingly uncertain world, the best way to offer Welsh households and industry the long-term certainty they need is by untethering the cost of electricity from unstable international gas markets.

Wales has seen significant progress in rolling out new renewables and, across the UK, renewables are already helping to squeeze gas off the grid. With demand for electricity set to grow as homes and industry electrify, more action is urgently needed to speed up the pace at which new renewables are coming online if the Welsh government is to meet its clean energy targets and prevent Wales becoming more dependent on imported electricity”.

The crisis in oil and gas markets has accentuated concerns about the UK’s dependence on imported energy, with last year’s National Security Assessment stating that the UK needed to reduce its energy reliance on other nations. According to polling conducted by More in Common on behalf of the ECIU, seven in ten Welsh voters (70%) expressed concerned about Wales being dependent on energy imported from the United States and nearly as many (67%) about Wales being reliant on energy imported from the rest of the world.

In recent years, the United States has become the UK’s largest supplier of liquefied natural Gas, supplying 68% of UK imports. This has led experts to warn of the possibility of the Trump administration leveraging energy supplies to extract policy concessions from European governments.
