Cuba is on the brink of transforming its energy landscape with a bold plan to invest $8bn in renewable energy, which could reduce its reliance on fossil fuels and pave the way for energy independence from the US. The proposal, put forth by the Common Wealth thinktank's Transition Security Project (TSP), suggests that this investment could cover 93.4% of Cuba's electricity generation needs.The US has imposed a crippling energy blockade on Cuba, severely limiting the island nation's access to oil. Since January, Cuba has received only one shipment of oil, from Russia, and its national electric grid has collapsed, leading to repeated blackouts and widespread disruptions.The TSP analysis outlines four different scenarios for Cuba's transition to renewable energy, with costs ranging from $5bn to $19.2bn. The most ambitious proposal would see three-quarters of electricity generation provided by solar power, with wind, hydropower, and bioenergy making up the remainder.The report argues that electricity costs would decrease in every renewable investment scenario, with the cost per unit of energy falling from 14.3¢ per kWh in the baseline scenario to 6.5¢ with $8bn of investment. The transition would require a society-wide transformation, but Cuba has demonstrated its ability to adapt in the past, such as its rapid shift to agroecology and self-sufficiency in the 1990s.The question remains: who would pay for this transition? The report suggests that financing should be understood as "reparative climate finance", with Cubans able to pay back investments through savings on cheaper energy. The transformation would not only benefit Cuba but also set an important example of a rapid energy transition under conditions of external constraint.

Iran has strongly condemned YouTube's decision to ban a pro-Iranian group, Explosive Media, which creates Lego-style artificial intelligence videos. The group was suspended for allegedly posting 'violent content', specifically a video mocking US President Donald Trump and declaring 'Iran won' after a recent ceasefire agreement. The ban has sparked outrage from Iran's Ministry of Foreign Affairs, with spokesman Esmaeil Baghaei accusing YouTube of trying to suppress the truth about the US-Israel war on Iran. Baghaei questioned the ban, highlighting that YouTube hosts content from major animation studios like Pixar, DreamWorks Animation, and The Walt Disney Company. Explosive Media's videos often use US popular culture to portray Trump as isolated and prone to childish tantrums. One video depicted Trump with an oversized yellow head and a flaming backside, holding a sign that read: 'VICTORY! I am a loser'. The group describes itself as independent but is widely suspected of having ties to the Iranian government. The ban has been seen as an attempt to shield the American administration's false narrative from competing voices. Iran's Foreign Ministry has expressed concern that such actions could limit the free flow of information and perspectives on the ongoing conflict.

The App Store Removal Apple is taking a tough stance on vibe-coding apps, blocking updates or removing those apps from the App Store. Affected apps include Replit, Vibecode, and Anything. While Replit and Vibecode's updates were paused, Anything's app was removed twice. Anything's Struggle with Apple Anything's co-founder, Dhruv Amin, said in a conversation with TechCrunch that Apple removed its app on March 26. Since then, the company has been unable to get its app approved, despite a period where there was a brief reinstatement. Apple cited developer agreement clause 2.5.2, which prevents apps from downloading, installing, or executing code. The app markets itself as a mobile app builder for iPhone and advertises making native iOS apps with features like 1-tap App Store submissions, code export, and full source code editing. The Impact on Anything Amin noted that when the company managed to get on a call with Apple, the iPhone maker told them that the vibe-coding app was removed because of the potential it could be used to download malicious code. The Future of Anything Following the battle with Apple, Anything's maker is looking for other ways to allow people to build mobile apps. Earlier this month, the company launched a feature that let users build apps using the iMessage platform. The company said it will also build a desktop companion app that lets users vibe code mobile apps on their computer. The company may instead look at Google's Android operating system for building its apps, as the platform is more open than iOS. Epic Games CEO Tim Sweeney has been vocal about Apple's tactics, saying that Apple needs to "stop blocking development tools apps ASAP." The Broader Implications Earlier this month, The Information reported that thanks to AI-powered coding tools, Apple saw an 84% jump in app submissions in a single quarter. This could force Apple to change its human-led review processes. As AI-powered coding takes off, consumers might demand that platforms like Apple allow them to create apps for themselves.

In an internal email circulated on Tuesday, Disney’s newly appointed CEO Josh D’Amaro disclosed plans to cut about 1,000 jobs as part of a broader effort to streamline the conglomerate’s operations.The reductions will primarily affect the recently restructured marketing division and extend to several other segments, including the studio and television arms, ESPN, product and technology teams, as well as select corporate functions.D’Amaro emphasized the need for a “more agile and technologically‑enabled workforce” to keep pace with the rapid evolution of the entertainment landscape, noting that the cuts are essential to meet future demands.These layoffs come as Disney, like many of its Hollywood peers, confronts a challenging economic backdrop characterized by a weakening television market, declining box‑office receipts, and intensified competition from rivals such as Warner Bros. Discovery and Paramount‑Skydance.The company’s most extensive workforce reduction occurred in 2023, when it announced a cut of 7,000 positions to achieve roughly $5.5 billion in cost savings, a move spurred by pressure from activist investor Nelson Peltz to improve financial performance and curb streaming losses.According to Disney’s latest fiscal data, the firm employed approximately 231,000 people as of September, the close of its fiscal year. The Wall Street Journal first reported the current round of job cuts.

The International Monetary Fund (IMF) has issued a stark warning that a further escalation in the Iran war could lead to a global recession, spiralling inflation, and a sharp backlash in financial markets. The Washington-based fund cited the economic damage from the Middle East conflict as steadily rising, prompting it to cut its growth forecasts for 2026.In its half-yearly update, the IMF predicted that the UK would suffer the sharpest growth downgrade and joint highest inflation rate in the G7 this year. Even if the fallout from soaring energy costs can be contained by the middle of 2026, the fund warned of a close call for a global recession under a worst-case 'severe scenario'.This severe scenario, involving a drawn-out war and persistently higher energy prices, would see the world face a global recession for only the fifth time since 1980. Oil prices jumped back above $100 (£74) a barrel on Monday amid choppy trading in global markets. The IMF's chief economist, Pierre-Olivier Gourinchas, noted that despite a temporary ceasefire, some damage is already done, and downside risks remain elevated.The IMF set out three possible scenarios for the war in its World Economic Outlook (WEO), including a central 'reference forecast' based on the assumption that disruption to the world economy from the war fades by mid-2026. This forecast predicts global growth would fall from 3.4% last year to 3.1% in 2026, a downgrade of 0.1 percentage points.Under the adverse scenario, with the global oil price remaining at $100 this year before falling back to $75 in 2027, growth would fall to 2.5% this year, and inflation would rise to 5.4%. In the severe scenario, with a lengthier, intensive war keeping the oil price above $110 into 2027, global growth would collapse to about 2%, a threshold widely seen as equivalent to a worldwide recession.The IMF urged countries to stage a coordinated response to the economic fallout from the war and called on central banks to remain vigilant. It also advised governments to focus on temporary and targeted measures to support businesses and households.

Tanya Khovanova has long been a leading voice in the world of recreational mathematics, authoring a popular blog and running the Number Gossip site where enthusiasts can inquire about any number.She now debuts her first book, Mathematical Puzzles and Curiosities, co‑written with fellow puzzle‑enthusiasts Ivo David and Yogev Shpilman. Published by World Scientific, the volume offers fresh challenges and inventive twists on classic problems.To give readers a taste, Khovanova selected three puzzles for the Guardian column:1. Battleships – As a naval admiral you must choose between sending a single vessel with a success probability of P % or two vessels each with a P/2 % chance, where the mission succeeds if at least one ship does. Which strategy maximises the odds?2. The Two Oracles – You face two respondents, Randie, who answers randomly, and Rando, who randomly decides to tell the truth or lie before each answer. Is there a method to distinguish them?3. Bad Maths – A student computes 5548 − 5489 as 59, claiming the “548” cancels out. He then experiments with a subtraction of the form XXYZ − XYZW (distinct digits) and observes the result is XW. How many digits in the new expression match those in the original calculation?Solutions to the trio were later posted online (update), but readers were urged to avoid spoilers until the scheduled reveal.Khovanova also reminds fans that she has been curating puzzles for the Guardian every other Monday since 2015 and welcomes new submissions via email.

More than 1,000 film and television professionals have signed an open letter opposing Paramount’s pending acquisition of Warner Bros Discovery, a deal valued at $111 billion. The signatories include high‑profile names such as Joaquin Phoenix, Ben Stiller, Mark Ruffalo, Yorgos Lanthimos, Kristen Stewart, Jane Fonda, and Emma Thompson.The letter, published on BlocktheMerger.com, warns that the merger would undermine the integrity, independence and diversity of the U.S. media sector, consolidating the number of major studios to just four and jeopardising a "vibrant future" for what it calls America’s "single most significant export" – its cultural content.Signatories argue that media consolidation already weakens competition, leading to fewer mid‑budget films, reduced independent distribution, higher production costs and fewer jobs across the ecosystem. They stress that competition is essential for both a healthy economy and a healthy democracy.Among the notable supporters are directors Denis Villeneuve, Boots Riley, Mimi Leder and Nicole Holofcener, as well as TV veterans David Chase, Noah Wyle, Ramy Youssef, Rob Delaney, Jason Bateman and Ted Danson. The letter also praises California Attorney General Rob Bonta and other state officials for scrutinising the deal.Paramount CEO David Ellison, who outbid Netflix for Warner Bros, claims the merger will boost creative output, pledging to release 30 theatrical titles annually and invest in both studios. Critics, however, remain skeptical, pointing to the Ellisons’ political ties and the risk of fewer politically‑engaged films.Recent accolades underscore the stakes: Warner Bros productions captured a record 11 Oscars in March, while Paramount films earned no nominations. The industry fears that the combined entity could further diminish quality and lead to significant job losses.Paramount has responded with a statement emphasizing that the transaction will “create a company that can greenlight more projects, back bold ideas, support talent across multiple stages of their careers, and bring stories to audiences at a truly global scale—while strengthening competition.” The letter’s authors remain unconvinced, urging regulators to block the merger to preserve competition, protect jobs, and safeguard the cultural export that defines American cinema.

The world of teen text abbreviations can be confusing, especially for adults trying to keep up. SYBAU, WYLL, and PMO are just a few examples of the latest abbreviations that have left many grownups scratching their heads.Research by the anagram website Unscramblerer.com has revealed the most confusing examples of teen text abbreviations. SYBAU, for instance, is often mistakenly believed to mean 'stay young, beautiful and unique.' However, its actual meaning is far more explicit: 'shut your bitch ass up.'WYLL is another abbreviation that has sparked curiosity. While some might think it means 'would you levitate lightly,' it actually stands for 'what you look like.' PMO, on the other hand, has two possible meanings: 'put me on' or 'pisses me off.'The list also includes other popular abbreviations like WFH (work from home) and TBH (to be honest). However, not all abbreviations are as straightforward. ASL, for example, is often believed to mean 'age, sex, location,' but research suggests it actually means 'as hell.'The use of text abbreviations has become such an entrenched cultural norm that their use has now ossified, meaning parents no longer have to fear the worst about what their children are communicating. As one commenter joked, 'I will stay young, beautiful and unique. Thank you.'
