In the week of the UK’s fifth heatwave, in which temperatures in parts of England hit 38C, the property website Rightmove said the heat was influencing how Britons thought about their homes, with more people paying attention to how comfortable a property would be during hotter weather.

Searches on its site this summer for homes for sale with air conditioning were up 104% compared with the same period last year.

The website also published consumer research showing that 61% of people said they would consider installing air conditioning, though only 12% had already done so. Meanwhile, 87% said that a property’s ability to stay cool was important when choosing their next home.

A report published in May by the UK’s Climate Change Committee said hotter heatwaves could lead to 92% of existing homes overheating by 2050, adding that they may require air conditioning. Passive measures such as drawing curtains and opening windows were unlikely to be enough.

An estimated 4m homes in the UK now have air conditioning, double the figure from three years ago. The rise in working from home is thought to have fuelled demand.

Some of the UK’s warmest summers have been in recent years, and the UK’s hottest day was in July 2022, when temperatures hit 40C.

In May, the air conditioning specialist Debonair Cooling told the Guardian that owners of both period and new-build properties were enquiring about its cooling systems – which cost about £2,500 per room. “They are struggling to sleep at night, or have children with breathing problems,” it said, adding that loft conversions were also posing problems, with some loft rooms reaching highs of 50C.

In the US and Japan at least 90% of households are said to have air conditioningwhereas for Europe as a whole it is estimated that fewer than a quarter have air conditioning.

Air conditioning is controversial as it is energy intensive, accounting for about 4% of global greenhouse gas emissions. However, some people in the UK with heat pumps have been able to use them to cool their homes as well as heat them, which could increase demand for the technology.

Rightmove’s property expert, Colleen Babcock, said: “While location, space and affordability remain key priorities, our research suggests that people are paying closer attention to how comfortable a home will be during hotter weather.

“Many households are already making practical changes to keep cool, while others are factoring these considerations into their next move.”

James Waight, head of sales at the estate agent John D Wood & Co, said a home that could stay cool in summer while also retaining heat in winter was “no longer simply a nice-to-have but an important factor in the decision to buy a property”. %!s()

The spread between U.S. COMEX futures and London Metal Exchange prices has historically been used by physical traders, banks, hedge funds, producers and consumers to profit from temporary price differences and hedge against price risk between the two markets.

The arbitrage was historically driven by factors such as Chinese demand shocks or supply disruption in South America.

Now, though, Societe Generale analysts say the trade has been upended by the prospect of fresh Section 232 tariffs on refined copper, pending a White House investigation, with investors increasingly using the COMEX premium as a gauge of further duties.

The U.S. already charges a 50% levy on imports of semi-finished copper products and certain other products made with copper. The Commerce Department has recommended a phased universal tariff of 15% on refined copper from Jan. 1, 2027, rising to 30% on Jan. 1, 2028.

Copper.

"The COMEX-LME spread has increasingly become a gauge of U.S. tariff expectations, with a wider premium signaling greater perceived tariff risk and continuing to pull metal into the U.S.," Ewa Manthey, commodities strategies at ING, told CNBC via email.

The U.S. imported more than 200,000 metric tons of copper in July — its highest level in 12 years.

SocGen analysts led by Mike Haigh, head of FIC and commodity research, said U.S. policymakers have become increasingly concerned about the country's reliance on imported refined copper as AI infrastructure, grid modernization, and defense spending turbo-charge global demand.

Its Section 232 probe reflects a broader objective in "securing access to a material seen as critical to both economic growth and national security," he said

Copper tariff forecasts

To translate the spread into tariff odds, SocGen modelled the cost of moving LME-grade copper from European warehouses to the U.S. East Coast, and compared that all-in delivered price with COMEX futures. Analysts said the current COMEX premium over fully delivered LME metal implies a 14.6% likelihood of the Commerce Secretary's recommended phased universal tariff of 15% by January 2027.

That rises to a 37% probability of a 30% duty by January 2028.

Natalie Scott-Gray, senior metals demand strategist at StoneX, said the overdue U.S. Section 232 decision on refined copper is now the "single biggest catalyst" facing the copper market. In a recent market commentary, Scott-Gray said comprehensive tariffs would squeeze supply outside the U.S. In contrast, no tariffs would unwind the COMEX-LME arbitrage.

Manthey said a wider premium remains supportive for copper prices near term, "particularly as mine supply remains tight and competition for available metal between the U.S. and China intensifies."

"We remain constructive on copper, although tariff uncertainty means volatility is likely to stay elevated," she added. %!s()

The track is an adoring portrait of an unnamed woman, with Sivan coolly narrating everything about her: her appearance, quirks, overall demeanor. Maybe they’re mundane observations to the average person, but to Sivan, every detail is magic. “That girl, wow,” he sings, awestruck. “She’s the best.”

“She’s The Best” was written and produced by Sivan, Jack Antonoff, Leland, Styalz Fuego, and 1975 drummer and Charli XCX husband’s George Daniel, who Sivan had never worked with before. A small snippet at the end includes a special guest: “The vocal that you hear at the end of ‘She’s the Best,’ it’s Charli,” Sivan said during a recent conversation in the Rolling Stone Studio. “We’ve found ways to work these women into the songs. I don’t want to speak for him, but I think for both George and I, Charli is obviously a very, very, very special person to both of us, and so to have her on that song in some small way is very meaningful to us.”

Sivan describes the anecdotes in the song as a collage of, and love letter inspired by, several women in his personal life. “To be able to have made music with Ariana [Grande] or Lily-Rose Depp, then touring with Charli [xcx] and growing up alongside her…I’ve always just loved being in the orbit of these women,” he said.”

“‘She’s the Best’ was the first time I wasn’t trying to psychoanalyze myself, and I wasn’t writing about men,” he added. “The one thing that has been constant in my whole life is the women in my life, and the feminine people in my life.”

The song’s accompanying music video stars Australian actress Nicole Kidman, who Sivan first met in 2018 on the set of the film Boy Erased — and where he first got her phone number. “She’s always just been such a picture of the divine feminine to me,” he said.

“I sent her the song and I showed her some references for the video,” he remembered. In the middle of a Zoom meeting a bit later, he received a call from an unknown number. “I let it go to voicemail, and then I see the transcription starts coming, it’s like, ‘Hi darling Troye, it’s Nic.’ I slammed my laptop shut and just ended the meeting.”

‘She’s the Best,’ Sivan’s first album since 2023’s Something to Give Each Other, arrives on Oct. 9. “There is this high-octane side to the album that feels really bombastic, and then there are the songs that feel like the interior of my mind. There’s this deep sense of longing. The album is a crazy journey,” Sivan said. %!s()

The media platform’s website, which has a sign-up for its newsletter, describes its origins: “One day, we were all talking about it and realized there was no easy, inclusive space where people could come together to explore, discuss, and navigate their feelings. So we thought, why not make it happen? And Wondermind was born.”

Now, five years after it began, Wondermind and its founders are being sued by investors who claim they pumped nearly nearly $1.2 million into Wondermind Global Inc. and were fed false promises about the company’s infrastructure, leadership, and resources.

According to a new lawsuit filed on Wednesday, investors were led to believe that a groundbreaking Wondermind app would be made, advertising deals would be struck, and celebrity cover stories were already underway. Instead, the complaint alleges, “for three years, while the Company quietly collapsed around them, not one of its founders, officers, or directors said a word to the investors whose money was funding the collapse.”

The trio and Wondermind are being sued for securities fraud, common law fraud, and breach of contract. The plaintiffs are seeking rescission of their investments in Wondermind, along with damages and costs.

The lawsuit also claims that investors were not aware of the full facts behind their alleged claims until The Cut published an article into the startup’s operations last year, which reported relationship tensions between Gomez and her mother, as well as a power struggle between Teefy and Pierson. The report revealed the “utter disarray” of the company to the plaintiffs including Teefy’s alleged “substance abuse disorder and her gross mismanagement” of the company; Gomez’s “abject dereliction of her duties” and “her active efforts to distance herself from it”; and the startup’s failure to fulfill basic obligations such as “paying its employees and vendors” on time.

Trending Stories

Pierson — who was ousted from Wondermind in 2023 — is the sole defendant in another securities fraud claim, which alleges she made misstatements to investors to encourage their purchases of stock, and is also accused of conversion and unjust enrichment. The suit cites an August 2025 article by Forbes that alleged Pierson inflated the readership and valuation of her lifestyle newsletter during business pitches. Pierson is also accused of misappropriating investment funds for her “own personal purposes” and having “impoverished the Plaintiffs, without justification.”

Representatives for Wondermind, Gomez, Teefey, and Pierson did not immediately respond to requests for comment. %!s()

OpenAI's revolving door is still spinning.

The ChatGPT maker has lost a string of senior leaders in 2026, including former operating chief Brad Lightcap, applications CEO Fidji Simo, chief revenue officer Denise Dresser, and executives overseeing marketing, enterprise products, science, safety, and ethics. Some left to start new ventures, while some stepped back for health reasons.

The departures follow another year of turnover in 2025, when OpenAI lost its chief people and communications officers, a top researcher who went on to launch an AI-science startup, and at least seven researchers recruited by Meta.

Here are the prominent OpenAI leaders who have headed for the exits in 2026.

Denise Dresser

OpenAI announced in August that its chief revenue officer, Denise Dresser, is leaving the company. Dresser began the position in December 2025.

"Denise will leave OpenAI to pursue other opportunities following a transition period, during which she will work closely with the business team to support our customers," the company wrote in a blog post.

Dali Rajic will take over the role.

Brad Lightcap

Brad Lightcap, who worked at OpenAI since 2018, announced his departure on X in August. Lightcap told his followers that he's leaving the startup "to start something new."

"Over the last few months, I've been focused on the next horizon and what would stand in the way of mission success. I believe there are a few important new things the world will need to get right as we enter this next period," Lightcap said on X. "I'll have more to share soon, but I believe in OpenAI more than ever and am excited to help you all advance the mission from a different vantage point."

Lightcap began his tenure at OpenAI as chief financial officer before transitioning to chief operating officer in 2022. In April, OpenAI said Lightcap moved to a role focused on special projects.

Fidji Simo

In July, Fidji Simo announced she would step down from her role as OpenAI's CEO of applications and transition to a part-time advisor role. Simo, who was diagnosed with postural tachycardia syndrome, or POTS, in 2019, initially took medical leave in April.

"Over the last seven years, I've spent countless hours in doctors' offices, dealing with symptoms, treatments, insurance, uncertainty, and all the invisible work that comes with being a patient," Simo wrote on X in July. "Like millions of others living with chronic illness, I've experienced firsthand how difficult healthcare can be to navigate, even when you have every possible advantage."

Simo became the CEO of applications in May 2025.

Kevin Weil

Kevin Weil announced his departure on X in April.

"It's been a mind-expanding two years, from Chief Product Officer to joining the research team and starting OpenAI for Science," he said.

Weil first joined OpenAI in 2024 as its chief product officer. He later served as vice president of OpenAI for Science, an initiative to build an AI-powered platform to accelerate scientific discovery, starting in October 2025.

Currently, Weil heads an AI science startup that sought a valuation of at least $750 million.

Bill Peebles

Bill Peebles worked as a research scientist at OpenAI for three years before leaving the company in April 2026. Peebles served as the head of Sora, an AI model that uses text prompts to create videos.

"While the original Sora ignited a huge amount of investment in video across the industry, it took the next generation of models with Sora 2 for the broader public to understand the transformation happening," Peeble said on X. "I'm proud of all the sleepless nights before and after the launch this team endured in order to deploy the technology in a responsible way and help steer societal norms."

The video generation AI model first became available to users in December 2024. Nine months later, OpenAI released an updated model — Sora 2 — and an app meant to rival social media sites.

Although the app drummed up major hype, its momentum quickly faded.

OpenAI shut down Sora and its app this April.

Srinivas Narayanan

Srinivas Narayanan, OpenAI's chief technology officer for business applications, announced in April that he was leaving after three years.

"Leading the b2b engineering team has been an enormous privilege," Narayanan wrote on LinkedIn. "With the recent/upcoming product launches, this felt like the right time to step back."

Narayanan said he planned to spend time with his parents in India before deciding what to do next. He joined OpenAI as vice president of engineering and led teams working on ChatGPT and the company's enterprise products.

Kate Rouch

Kate Rouch stepped down as OpenAI's chief marketing officer in April to focus on her recovery from breast cancer.

Rouch joined OpenAI in December 2024 after more than a decade at Meta, where she served as global head of brand and product marketing. She took medical leave in 2025 while undergoing treatment, then returned to OpenAI.

OpenAI previously said Rouch could eventually return in a more narrowly defined position when her health allowed, and that the company was searching for a new chief marketing officer.

Barret Zoph

Barret Zoph left OpenAI in June, about five months after returning to lead its enterprise AI sales efforts.

Zoph initially departed OpenAI in September 2024 and cofounded Thinking Machines Lab with former OpenAI chief technology officer Mira Murati. He returned to OpenAI in January 2026 after leaving the rival startup.

OpenAI did not disclose why Zoph left.

Chloé Bakalar

Chloé Bakalar, OpenAI's head of ethics, left the company in July, less than a year after joining.

Bakalar joined OpenAI in August 2025 after spending about six years working on responsible AI at Meta. At OpenAI, she examined questions surrounding model behavior, human relationships with AI, and whether advanced systems could warrant moral consideration.

Johannes Heidecke

Johannes Heidecke, who led OpenAI's safety systems team, left the company in July amid a reorganization of its safety operations.

Heidecke joined OpenAI in 2021 and took charge of safety systems in 2024. His team evaluated models for potentially dangerous capabilities and developed safeguards intended to prevent harmful behavior.

Following his departure, OpenAI placed its safety teams under Mia Glaese, its vice president of research and safety.

Joshua Achiam

Joshua Achiam, OpenAI's chief futurist, left the company in July after nearly nine years.

Achiam previously led OpenAI's mission alignment team, which was tasked with helping the company uphold its founding goal of ensuring that artificial general intelligence benefits humanity. OpenAI disbanded that team in early 2026 and moved Achiam into the chief futurist role.

Caitlin Kalinowski

Caitlin Kalinowski, who led OpenAI's robotics and consumer hardware team, resigned in March over concerns about the company's agreement with the Pentagon.

"Surveillance of Americans without judicial oversight and lethal autonomy without human authorization are lines that deserved more deliberation than they got," Kalinowski wrote on LinkedIn. She later said her objection was primarily about governance and that the agreement had been announced before its safeguards were fully defined.

Kalinowski joined OpenAI in November 2024 after leading Meta's augmented-reality hardware efforts, including its Orion glasses project. OpenAI said its Pentagon agreement prohibited domestic surveillance and the use of autonomous weapons.
