Many of us have our own theories about sleep. Perhaps it’s avoiding coffee after lunch, drinking chamomile tea before bed, or having a warm glass of milk. But what does the science actually say?

In this episode of The Food Chain, Ruth Alexander explores the relationship between food and sleep, asking whether changing what we eat and drink can help us get a better night’s rest.

Professor Marie-Pierre St-Onge, Director of the Center of Excellence for Sleep & Circadian Research at Columbia University, explains what decades of research have revealed about the links between diet and sleep quality. She discusses why poor sleep can change our food choices, how certain dietary patterns are associated with better sleep, and why scientists are increasingly interested in nutrients such as fibre and tryptophan.

Sleep physician Dr Allie Hare, President of the British Sleep Society, brings the perspective of the clinic. She explains the questions patients ask most often, from caffeine and alcohol to herbal remedies and sleep supplements, and discusses some of the biggest misconceptions people have about improving their sleep.

Together, they explore whether there really are “sleep foods”, what role meal timing might play, and whether social media trends and expensive supplements are distracting us from the basics.

Along the way, they answer listeners’ questions and share practical, evidence-based advice on the changes people can make today to improve their chances of a good night’s sleep tonight.

Andy Burnham’s pledge to deliver the biggest shift of power away from Whitehall in modern history has won early backing from London’s business community, with leaders arguing the capital is just as hobbled by centralised policymaking as the regions it is so often accused of overshadowing.

Responding to the Greater Manchester mayor’s speech, which set out a vision for a “No 10 in the North” and a sweeping transfer of decision-making to local leaders, John Dickie, chief executive of BusinessLDN, said the direction of travel was exactly what the economy needed.

“Andy Burnham is right to put greater devolution at the heart of his agenda,” Dickie said. “Giving regions the powers they need to attract investment, upskill communities and deliver infrastructure is key to getting the economy moving again.”

The intervention is notable because BusinessLDN, the business membership group formerly known as London First, represents firms in a city frequently cast as the chief beneficiary of Westminster largesse. Dickie was quick to challenge that framing, arguing that proximity to Whitehall has done the capital few favours.

“It’s good to hear him backing London as the world’s greatest capital and setting out plans to devolve further powers to the city,” he said. “Contrary to the perception, proximity to Whitehall has not automatically worked in the capital’s favour and London is just as constrained by one-size-fits-all policymaking as other parts of the country.”

The crux of the business lobby’s case is that London punches below its weight on the powers and purse strings available to comparable world cities. The mayor of London currently holds fewer powers than counterparts in New York and Paris, and less financial freedom than the mayors of Greater Manchester and the West Midlands.

The numbers behind that argument are stark. London and its boroughs retain only around 7 per cent of the taxes raised in the capital, against more than 50 per cent in New York, according to BusinessLDN’s recent report on the new powers London needs to thrive. Roughly three-quarters of the city’s funding still arrives as central grant, much of it with strings attached.

That dependence sits awkwardly with London’s status as the engine room of the national economy, and analysts at the Institute for Government have long noted that the capital’s governance is best compared with Paris, New York and Berlin rather than with English regions of a very different size and shape. For BusinessLDN, the lesson is that a stronger settlement for London and a stronger settlement for the North are not competing demands but two halves of the same growth strategy.

Dickie also welcomed Burnham’s willingness to take on the structural problems that have dogged successive governments, singling out housing supply and the tax that falls hardest on the high street.

“The commitment to grappling with some of the long-standing thorny challenges facing the country, from housebuilding to reforming business rates, will also be welcomed by firms across the capital,” he said.

Both issues are live for the business community. Pressure for a wholesale overhaul of business rates has been building for years, with retailers, manufacturers and hospitality operators all warning that the current system penalises bricks-and-mortar firms and discourages expansion. The question of how far to go on fiscal devolution, meanwhile, has already been flagged by Chancellor Rachel Reeves as a piece of unfinished business, as the Treasury weighs handing more tax-raising and tax-retention powers to local leaders.

There are signs, too, that Burnham’s economic prospectus reaches beyond the machinery of devolution. His own advisers have floated ideas such as tying pension tax relief to British investment, part of a wider push to channel domestic capital into domestic growth.

For Dickie, the prize is ultimately about prosperity that is felt in people’s pockets, in the capital as much as in the North.

“The only way to improve living standards is through growth, and unleashing London’s potential is vital to achieving that, while also tackling the deep inequality and poverty that persists across the capital,” he said.

Whether Burnham’s blueprint survives contact with the Treasury, and with the political reality that any meaningful devolution means central government letting go, remains to be seen. But on the morning’s evidence, the business voices that are often assumed to defend the Westminster status quo are lining up behind a different model entirely, one in which power, money and accountability sit a good deal closer to the communities they serve.

BEAVER, Utah — Three firefighters died and two others were injured Saturday while battling rapidly spreading wildfires along the Colorado-Utah border, authorities said, as hot, dry and windy conditions fueled blazes across the drought-stricken West.

The fatalities occurred during a burnover on the Knowles and Gore fires in western Colorado’s Mesa County, where crews were part of an interagency response effort. The injured firefighters were transported to a hospital with burn injuries after deploying emergency shelters in a last-ditch effort to protect themselves from the advancing flames.

The U.S. Wildland Fire Service confirmed the deaths Sunday, describing the incident as a tragic loss during operations on the fast-moving fires. Hot, gusty winds and low humidity created dangerous conditions that caused the blazes to intensify quickly, overrunning the firefighters’ position.

Colorado Gov. Jared Polis expressed deep sorrow over the loss. “I’m devastated by the loss of three heroic firefighters who died in the line of duty,” he said in a statement.

The incident highlights the extreme risks faced by wildland firefighters as the wildfire season intensifies across the region. Prolonged drought, above-average temperatures and strong winds have created tinder-dry landscapes primed for rapid fire spread.

Multiple fires continue burning in Utah and Colorado, prompting firefighting resources to be stretched thin. In Utah, officials have imposed restrictions on fireworks ahead of the Fourth of July holiday due to extreme fire danger. The Snyder Fire, burning near the border, has scorched thousands of acres.

Fire officials urged caution and vigilance as conditions remain volatile. Crews are working around the clock to contain active blazes, but shifting winds and rugged terrain complicate suppression efforts.

The deaths come amid a challenging wildfire season in the Western United States. Climate patterns, including La Niña influences in some forecasts, combined with persistent dry weather have elevated fire risks. Experts warn that such conditions may become more frequent as the climate warms.

Wildland firefighting involves coordinated efforts from federal, state and local agencies. The fallen firefighters were part of a larger team responding to the border fires, which threatened communities and vast areas of public lands.

Investigations into the exact circumstances of the burnover are underway, a standard procedure following line-of-duty deaths. Officials will examine weather data, fire behavior models and deployment decisions to learn lessons for future incidents.

The two injured firefighters are receiving medical care, though details on their conditions were not immediately released. Support services for first responders and their families have been activated in the wake of the tragedy.

Across the West, other fires are also demanding attention. Utah has seen significant activity, with blazes forcing evacuations and road closures in some areas. Colorado has similarly grappled with multiple starts, taxing resources already committed to the border incident.

Fire managers emphasize the importance of public cooperation. Campfire restrictions, fireworks bans and awareness of dry vegetation help prevent human-caused ignitions, which account for a large percentage of wildfires.

The loss of three firefighters serves as a somber reminder of the dangers inherent in protecting lives, property and natural resources. Wildland firefighters often work in remote, hazardous environments with limited escape options when fires behave erratically.

Communities near the affected areas have rallied in support. Processions honored the fallen as news spread, with residents lining roads in Grand Junction and other locales to pay respects.

Federal and state leaders have pledged full support for ongoing firefighting operations and investigations. Resources from across the country are being mobilized to assist as the season progresses.

Climate scientists note that wildfire seasons are starting earlier and lasting longer in many regions due to changing weather patterns. Drier fuels and more extreme fire weather days increase both frequency and intensity of blazes.

For families of the deceased, the coming days will involve mourning and memorial arrangements. Fire agencies typically hold formal honors to recognize the ultimate sacrifice made in service to the public.

Meanwhile, containment efforts continue on the Knowles, Gore and other fires. Progress has been made in some sectors, but complete control remains elusive amid challenging conditions.

Residents in fire-prone areas are advised to prepare evacuation plans, maintain defensible space around homes and stay informed through official channels. Air quality alerts have also been issued due to heavy smoke in downwind communities.

The incident underscores the critical role of wildland fire management in the American West. As development expands into wildland-urban interfaces, the stakes for both firefighters and civilians continue to rise.

Support for wildfire prevention and suppression funding remains a priority for Western lawmakers. Investments in technology, training and fuel reduction projects aim to reduce risks, though experts acknowledge that complete elimination of danger is impossible.

As recovery and investigation efforts proceed, the focus remains on honoring the fallen and supporting their colleagues and loved ones. The bravery displayed in the face of such peril exemplifies the commitment of those who choose this demanding profession.

Broader weather patterns suggest the fire season may have more challenges ahead. Forecasts indicate continued hot and dry conditions across much of the region, necessitating sustained vigilance from both responders and the public.

NEW YORK — The Dow Jones Industrial Average climbed Monday as Wall Street welcomed reports that the United States and Iran had agreed to halt their tit-for-tat military exchanges, easing fears of a wider Middle East conflict that had rattled global markets heading into a holiday-shortened trading week.

The blue-chip index rose 141.70 points, or 0.27%, to close at 52,028.65, building on gains in futures trading that had pointed to a higher open from the early hours of the session. The advance followed a turbulent stretch for stocks, in which the Dow proved considerably more resilient than its technology-heavy counterparts, the S&P 500 and the Nasdaq Composite, both of which suffered sharp weekly losses last week.

The rally was driven largely by news that Washington and Tehran had agreed to stand down from further attacks, clearing the way for peace talks to resume in Doha this week. The de-escalation came after a tense weekend in which Iran targeted a container ship, a vessel carrying Qatari oil, and military installations in Kuwait and Bahrain, prompting retaliatory strikes from the United States. Those exchanges had tested an earlier agreement intended to pause hostilities during a 60-day negotiating window, and President Donald Trump had warned of the possibility of further American military action if Tehran continued to violate the truce. By Monday morning, however, two U.S. officials told CNN that both sides would “stand down for now” and that talks remained on track, helping calm investor nerves that had built up over the weekend.

Oil prices reflected the shifting mood only partially, rising modestly even as the immediate security threat appeared to ease. West Texas Intermediate crude climbed 0.85% to $69.82 per barrel, while Brent crude, the international benchmark, added 0.56% to reach $72.39 per barrel. The continued movement of oil tankers through the Strait of Hormuz throughout the recent escalation had already helped ease some of the more acute supply fears that initially gripped energy markets when hostilities first flared. Gold, meanwhile, slipped 1.07% to $4,052.30 per ounce, and silver fell 2.54% to $58.16 per ounce, as some investors rotated out of the safe-haven assets that had drawn heavy buying during the worst of the regional tension.

Monday’s gains came on the heels of a difficult week for technology stocks, which dragged down the broader market even as the Dow managed to eke out a 0.6% advance for the five trading days. The S&P 500 fell 1.95% over the same stretch, while the Nasdaq Composite tumbled 4.6%, its steepest weekly decline in some time. Megacap technology names bore the brunt of the selling, with Nvidia and Alphabet both sliding more than 8%, while Apple, Amazon and Meta each lost more than 4%. The pressure on the sector intensified after reports surfaced that OpenAI could be delaying its planned initial public offering, adding to broader unease about the pace of spending and returns tied to the artificial intelligence boom that has powered much of the market’s gains over the past several years.

Few names captured that volatility more dramatically than SpaceX, Elon Musk’s rocket and satellite communications company, which went public on June 12 in what has been described as the largest initial public offering in history. The stock plunged 17% last week, erasing nearly all of the gains it had notched since its market debut, before steadying somewhat in premarket trading Monday, when shares climbed 2.3% to $156.70. Nasdaq confirmed last week that SpaceX will be added to the Nasdaq 100 index on July 7, a milestone that will bring the newly public company into one of Wall Street’s most closely tracked benchmarks even as its stock continues to find its footing.

The Dow’s relative outperformance compared with the tech-heavy indexes has been helped along by a reshuffling of its own components. Alphabet replaced Verizon in the 30-stock index on Friday, a change that briefly exposed the Dow to more of the same technology-sector turbulence weighing on the Nasdaq, though healthcare stocks helped offset some of that pressure and kept the index near its record highs. Strength in defensive sectors, including healthcare, has been a recurring theme in recent sessions, with analysts noting that some of the broader market’s softness may simply reflect investors trimming equity exposure ahead of quarter-end portfolio rebalancing rather than a more fundamental shift in sentiment.

Markets are entering a holiday-shortened week, with U.S. exchanges closed Friday in observance of the Fourth of July holiday, which falls on Saturday this year. That compressed schedule has pushed back the release of the closely watched June jobs report, with the Labor Department’s nonfarm payrolls data now scheduled for Thursday instead of its usual Friday slot. The monthly employment report is considered a key input for the Federal Reserve’s interest rate deliberations, and economists have suggested early forecasts point to a notable slowdown in hiring after May’s surprisingly strong gain of 172,000 jobs.

Ahead of that release, investors have a steady stream of other economic data to digest this week, including June consumer confidence figures and the May Job Openings and Labor Turnover Survey, both due Tuesday, along with earnings from Nike and Constellation Brands. Wednesday’s calendar includes the ADP private payrolls report for June, construction spending figures and the Institute for Supply Management’s manufacturing index, which will offer an early read on factory-sector activity heading into the back half of the year. Inflation data released last week showed some signs of cooling, though investors remained cautious about exactly when the Federal Reserve might feel comfortable moving forward with additional interest rate cuts.

For now, Monday’s advance offered a measure of relief after a choppy stretch defined by geopolitical risk, a reshuffling tech sector and lingering questions about the durability of the artificial intelligence-driven rally that has underpinned much of the market’s gains over the past year. Whether that relief proves durable is likely to hinge on how the renewed diplomatic talks between Washington and Tehran progress in the days ahead, alongside a packed slate of economic data that will shape expectations for the Federal Reserve’s next moves heading into the second half of 2026.

LOS ANGELES — A widely used agricultural pesticide may pose a far greater threat to brain health than previously understood, according to new research from UCLA Health that links long-term exposure to the chemical chlorpyrifos with a sharply elevated risk of developing Parkinson’s disease, while also identifying a specific biological mechanism that may explain why.

The study, published in the journal Molecular Neurodegeneration, found that people with long-term residential exposure to chlorpyrifos had more than 2.5 times the risk of developing Parkinson’s disease compared with those who were not exposed. The research combined human population data with laboratory experiments in mice and zebrafish, providing both an epidemiological link and biological evidence to support it.

Researchers analyzed data from 829 people diagnosed with Parkinson’s disease and 824 individuals without the condition, all enrolled in UCLA’s long-running Parkinson’s Environment and Genes study. The cohort was drawn from three agricultural counties in central California — Kern, Fresno and Tulare — with participants recruited in two waves, one from 2000 to 2007 and a second from 2009 to 2015. To estimate each participant’s cumulative exposure to chlorpyrifos, the research team combined California’s Pesticide Use Report database, which has tracked agricultural chemical use in the state since 1972, with detailed residential and workplace address histories spanning decades.

Dr. Jeff Bronstein, a professor of Neurology at UCLA Health and the study’s senior author, said the findings move beyond general associations between pesticides and Parkinson’s to implicate one chemical specifically.

“This study establishes chlorpyrifos as a specific environmental risk factor for Parkinson’s disease,” Bronstein said, adding that the work does not simply lump pesticides together as a broad category but isolates this compound’s distinct contribution to disease risk.

To understand how chlorpyrifos might cause that damage, researchers turned to laboratory experiments. Mice were exposed to aerosolized chlorpyrifos through inhalation for 11 weeks, a method designed to mirror how people in agricultural communities are most commonly exposed to the chemical in real-world settings. The exposed mice developed movement problems and lost dopamine-producing neurons, the same population of brain cells that gradually dies off in people with Parkinson’s disease. The animals also showed signs of brain inflammation and an abnormal buildup of alpha-synuclein, a protein that clumps together in the brains of Parkinson’s patients and is considered a hallmark of the disease.

Additional experiments in zebrafish helped researchers pinpoint the underlying mechanism. The team found that chlorpyrifos disrupts autophagy, the cellular process responsible for clearing out damaged proteins and cellular debris before they can accumulate and cause harm. When autophagy was disrupted, neurons became significantly more vulnerable to injury. Critically, when researchers either restored the autophagy process or eliminated the synuclein protein in the affected cells, the neurons were protected from the pesticide’s damaging effects, pointing to a specific, targetable pathway rather than a vague or nonspecific form of toxicity.

Outside experts who reviewed the findings said the combination of human and laboratory evidence strengthens the case that chlorpyrifos plays a direct, causal role in some cases of Parkinson’s disease, rather than simply correlating with it. Dr. Michael Okun, a neurologist at the University of Florida and co-author of the book “Ending Parkinson’s Disease,” told The Associated Press that the results help explain the disease’s origins. The findings, he said, provide compelling evidence that this specific pesticide can initiate the biological cascade leading to Parkinson’s.

Nathan Donley, environmental health science director at the Center for Biological Diversity, framed the discovery within a broader pattern of research implicating the chemical in neurological harm, noting that chlorpyrifos has been linked to just about anything that can go wrong in the brain.

Chlorpyrifos is an organophosphate insecticide originally developed by Dow Chemical and introduced in 1965. It has been used for decades on a wide range of crops, including almonds, citrus and cotton. Residential use of the chemical was banned in the United States in 2001, and the U.S. Environmental Protection Agency further restricted its agricultural applications in 2021, but it remains approved for use on close to a dozen crops domestically and continues to be widely used in agriculture in many other countries around the world.

The new findings add to a growing body of research connecting chlorpyrifos exposure to neurological harm across different stages of life. Earlier research has linked the pesticide to impaired brain development and reduced motor function in children exposed during pregnancy or early childhood, building on a string of prior studies examining the chemical’s effects on developing brains. The new UCLA research is among only a handful of studies to specifically investigate chlorpyrifos’s potential role in causing Parkinson’s disease in adults, an area that had previously relied mostly on animal studies showing that the chemical can induce cell death and alter or eliminate neurons, both recognized markers of the disease.

The research arrives amid a broader wave of scientific and legal scrutiny of pesticides and their potential links to Parkinson’s disease. A separate chemical, the herbicide paraquat, has drawn significant attention in recent years after internal corporate documents revealed that Syngenta, the company that manufactures and markets the product, was aware of research linking paraquat to brain disease decades ago. Syngenta now faces thousands of lawsuits from individuals who allege that paraquat exposure caused them to develop Parkinson’s disease, a separate legal and scientific track from the chlorpyrifos findings but part of the same broader push to understand how environmental chemicals may contribute to the disease.

Parkinson’s disease affects nearly 1 million Americans and is characterized by the gradual loss of dopamine-producing neurons in the brain, a process that leads to symptoms including tremors, muscle stiffness, slowed movement and difficulty with balance and coordination. While certain genetic factors are known to raise risk, researchers have increasingly turned their attention to environmental exposures, including pesticides, as important contributors to the disease’s development. There is currently no cure for Parkinson’s, though treatments such as the medication levodopa, along with rehabilitation therapies and, in some cases, surgery, can help manage symptoms and improve quality of life.

The UCLA researchers say their discovery that autophagy dysfunction drives much of the neurotoxicity observed in their experiments points toward a promising new therapeutic target, raising the possibility that future treatments could focus on restoring or boosting the brain’s natural cellular cleanup processes to protect vulnerable neurons. The team also said people with known historical exposure to chlorpyrifos, particularly those who lived or worked near treated agricultural fields for extended periods, might benefit from closer neurological monitoring going forward. Researchers noted that while chlorpyrifos use has declined in the United States in recent years, many people were exposed before current restrictions took effect, and similar organophosphate pesticides remain in widespread use around the world, suggesting the public health relevance of the findings extends well beyond U.S. borders.

LONDON — Maja Chwalińska’s stunning rise from French Open qualifier to Grand Slam finalist hit a painful setback Monday, as the Polish player suffered an ankle injury while holding match point against Thai qualifier Mananchaya Sawangkaew and ultimately fell in three sets in the first round of Wimbledon.

Chwalińska, the 2026 French Open runner-up who was given a wild card into the Wimbledon main draw and seeded No. 20 as a result of her run in Paris, dominated the early stages of the match on Court 12. She had moved ahead 6-2, 5-2, holding a 30-40 advantage on Sawangkaew’s serve when she fell awkwardly while chasing down a forehand winner down the line. The 24-year-old called for a medical timeout immediately afterward and received treatment to her right ankle, with a trainer applying strapping to the area before she attempted to continue serving out the match.

What followed was a dramatic collapse. Chwalińska’s movement, the foundation of the aggressive, court-covering style that had carried her to the final at Roland Garros earlier this month, deteriorated rapidly. Sawangkaew, ranked No. 164 and playing in her first-ever Grand Slam main draw match, seized the opportunity, converting three break points to level the second set before reeling off five consecutive games to claim it outright. The Thai player went on to close out a 2-6, 7-5, 6-2 victory, ending what had briefly looked like a routine progression for the Pole into the second round.

Between the second and third sets, Chwalińska left the court for approximately eight minutes for further treatment. She returned and managed to secure an early break in the deciding set, but continued to grimace and stretch out her leg and back between points, visibly restricted in her movement and unwilling to chase down anything beyond her immediate reach. Sawangkaew leveled with a break to love shortly afterward, and the match turned into something of a procession from that point on, with the Thai qualifier eventually breaking again to take control for good as her own unforced errors dried up.

The collapse echoed a similar scene from earlier this season, when Jannik Sinner’s level fell apart while serving for victory against Juan Manuel Cerúndolo in the second round of the French Open, with physical issues undercutting what had appeared to be a comfortable lead. For Chwalińska, the parallel will sting in particular given the magnitude of what she had been building toward at the All England Club.

The defeat came just over three weeks after Chwalińska’s run to the Roland Garros final, where she lost to Mirra Andreeva 6-3, 6-2. That run made her the first qualifier in history to reach a French Open women’s singles final, propelling her more than 90 places up the WTA rankings and elevating her to a career-high of No. 21 in the world. The surge in ranking points was enough to earn her a seed at Wimbledon, but her position was still too low to gain direct entry into the main draw when the original entry lists were finalized, requiring organizers to grant her a wild card to ensure she could compete.

That wild-card-plus-seed combination made Chwalińska’s situation at Wimbledon an unusual one heading into the tournament. Adding to the uncertainty was her lack of recent grass-court form: Chwalińska had not played an official match on the surface since a first-round qualifying loss at Wimbledon in 2025, leaving her with no competitive grass-court reps over the previous 12 months heading into Monday’s match. Her career grass-court record stood at 7-6 entering the tournament, modest by comparison with her broader career mark of 277-139 and her strong 2026 season, in which she carried a 29-10 win-loss record into the tournament, highlighted by a title run in Oeiras earlier this year.

Sawangkaew, by contrast, arrived in good form on the surface despite her relative inexperience at the highest level. The Thai player came through three qualifying matches in three sets over the preceding week to reach the main draw, defeating Anouk Koevermans, Mary Stoiana and Océane Dodin along the way, and entered Monday’s match having won seven of her last nine matches on grass. Her composed 30-11 record for the season included a 7-2 mark specifically on grass, and her ability to convert break points under pressure proved decisive once Chwalińska’s movement became compromised.

Pre-match betting markets had favored Chwalińska to advance in three sets, reflecting her superior ranking and recent Grand Slam pedigree, even accounting for her unfamiliarity with grass this season. Instead, the match will be remembered for the moment Chwalińska’s title hopes unraveled in an instant, transforming what had been a near-certain second-round berth into a deflating first-round exit.

Beyond the immediate disappointment of the loss, questions now turn to the severity of Chwalińska’s ankle injury and what it might mean for the remainder of her season. She remains entered in the women’s doubles draw at Wimbledon, though it remains unclear whether she will be fit enough to compete in that event following Monday’s injury. For a player who only weeks ago was redefining what was possible for a Grand Slam qualifier, the abrupt end to her Wimbledon campaign serves as a stark reminder of how quickly fortunes can turn in professional tennis, even at the moment of apparent triumph.

Ford says it has hired back some human engineers after AI failed to match their skills and experience.

In a bid to reap the benefits of the tech, which developers claim can cut costs and boost productivity, the US carmaker adopted it across some parts of its operations including for quality checks.

But, according to Bloomberg, external, its executives said the firm has rehired more than 300 “veteran” quality inspectors in recent years to make up for the pitfalls of automated systems.

“Artificial intelligence is a fantastic tool, but it’s only as good as the information you use to train it,” Charles Poon, vice president of vehicle hardware engineering, told reporters.

“Over prior years, we didn’t pay as much attention as we should have to the experience of our most knowledgeable engineers that have been with us through many product cycles,” he said.

The US automaker is among many to have seized on the buzz around AI, particularly amid Wall Street fervour about the tech’s potential to increase margins.

“AI will leave a lot of white collar people behind,” Ford boss Jim Farley said in an interview with author Walter Isaacson last June.

In an October earnings call, external, chief operating officer Kumar Galhotra said the firm was “deploying AI across the entire industrial system”.

This included rolling out 900 AI-powered cameras in its plants “to detect quality issues at the source and help us mitigate supply disruptions”, Galhotra told investors.

But Poon told reporters on Wednesday the firm’s AI-driven checks had failed to live up to expectations.

“Mistakenly, we thought that by just introducing artificial intelligence and ingesting the design requirements that we had, that would produce a high-quality product,” he said.
