The US Environmental Protection Agency (EPA) has announced a temporary waiver allowing the sale of a higher-ethanol fuel blend, known as E15, in an effort to alleviate soaring gas prices that have been exacerbated by the ongoing Iran war.E15, which contains a higher percentage of ethanol than standard gasoline, has been prohibited during warm weather months due to concerns over its potential to worsen smog. However, the EPA's decision, supported by the US agriculture secretary, Brooke Rollins, aims to provide relief to consumers at the pump.“President Trump is unleashing American Energy Dominance, and today’s action will directly lower prices at the pump and gives a clear demand signal to our domestic biofuels producers,” Rollins stated.The summer waiver for E15 has become a recurring measure in recent years, with both Republicans and Democrats advocating for its permanent implementation to reduce fuel costs. Currently, E15 is already permitted in several states, including Iowa, Illinois, Minnesota, Nebraska, Missouri, Wisconsin, and most of South Dakota.However, not all experts are convinced that the move will significantly lower gas prices. Kenneth Gillingham, a professor at the Yale School of the Environment, pointed out that E15 is not widely available in all states, and some areas lack the necessary infrastructure or sufficient ethanol supply to support increased use.Gillingham also highlighted potential risks associated with E15, particularly for older vehicles, boats, and all-terrain vehicles, due to its higher corrosive ethanol content. Additionally, increased corn usage for ethanol production could lead to higher costs for animal feed and, subsequently, grocery prices.“I think it’s difficult to see when the ledger’s settled how this is a benefit for US consumers,” said Jason Hill, a professor at the University of Minnesota.The decision has also drawn criticism over its potential environmental impacts, with concerns about increased ozone issues, respiratory problems, and even premature deaths.While the oil industry has generally opposed the expansion of E15, citing costly biofuel blending and potential price increases, the American Petroleum Institute has expressed support for the temporary waiver, emphasizing its role in ensuring affordable and reliable energy for American consumers.

The deadly conflict in Iran has precipitated what the International Energy Agency describes as the worst oil crisis in history, creating a complex situation for global clean energy efforts. While climate advocates are calling for accelerated transition away from fossil fuels, the war simultaneously presents both opportunities and significant challenges for renewable energy development.US-Israeli strikes on Iran have critically disrupted supply routes through the Strait of Hormuz, a maritime channel through which 20% of global oil flows. The conflict has also seen direct attacks on fossil fuel infrastructure by all parties involved, creating additional market shocks and uncertainty.Interestingly, reduced reliance on oil and gas is proving beneficial for some regions navigating the ongoing fuel crisis. As Jan Rosenow, a professor of energy at Oxford University, explains: Electricity generated from wind and solar is largely insulated from fossil fuel price volatility – once built, the fuel is free.Countries with substantial renewable energy investments are demonstrating greater resilience. Spain and Portugal have witnessed electricity prices decline in recent weeks, while Pakistan has experienced a surge in rooftop solar installations over the past five years, helping the nation weather oil and gas market disruptions.The electric vehicle revolution is also providing some economies with protection against gasoline price increases. In China, more than 50% of all new cars sold are electric, while in Nepal, that figure reaches an impressive 70%.However, the war is creating near-term challenges that could impede clean energy growth. The conflict has disrupted transport routes for metals essential in solar panel construction, particularly aluminum. The Middle East accounts for approximately 9% of global aluminum production, and regional producers have begun scaling back operations amid the hostilities.Furthermore, the inflationary pressures stemming from the conflict pose significant hurdles for renewable energy projects, which require substantial upfront investment for construction, equipment, and installation.Paradoxically, the war and resulting energy shocks have provided a short-term boon for fossil fuels, including coal. Many Asian countries heavily reliant on imported liquefied natural gas (LNG) are burning more coal to meet energy demand as LNG supplies through the Strait of Hormuz become constrained.The conflict has also incentivized increased oil and gas drilling and exploration, as countries scramble to replace disrupted LNG supplies and higher prices make previously unviable projects economically viable. US company Venture Global recently announced a new five-year contract to supply LNG, while Canadian energy company TC Energy indicated that Iran war disruptions are increasing the likelihood of expanding a massive LNG export facility.The Trump administration has further incentivized oil expansion, recently announcing plans to pay a French company $1 billion to abandon offshore wind farm projects in favor of fossil fuel initiatives.Experts propose various policy responses to encourage the green transition during this crisis. Rosenow advocates for tax reform to reduce the disproportionate burden on electricity compared to gas. Professor Gregor Semieniuk suggests imposing windfall taxes on oil and gas companies during the war, while Lauren Pagel of Earthworks calls for ending fossil fuel subsidies and making polluters pay for their environmental impact.Despite the current challenges, Kingsmill Bond, a strategist for the energy thinktank Ember, maintains that this crisis could ultimately accelerate the clean energy transition: This is the first oil shock in history where oil faces a superior alternative. Solar, wind and EV are cheaper, local, faster to deploy, and huge.

Egil Johansen, the landlord of the Kenton pub in Hackney, east London, describes recent incidents involving children as "like the wild west." He has now banned children entirely after a three-year-old fell down a cellar hatch while parents sat elsewhere, a five-year-old crashed into staff carrying drinks, and six parents brought 10 hyperactive children after a birthday party while ignoring their behavior."In every case, the parents blame us when something goes wrong or get really angry when we ask them to control their children," says Johansen, who has run the pub for 17 years. "I'm legally obliged to keep children safe on my premises and if the parents let their children run riot, the only answer is to not allow them in at all."Johansen initially tried banning children only after 5pm, but this interim measure failed to address the underlying issues. Despite online criticism framing him as the "baddie," he expresses sadness about the situation: "I'm a publican; I'm a people-person. It gives me no joy to ban anyone, but it's just not safe: parents don't control their children and our other customers were beginning to go elsewhere. I had no choice."The Kenton's decision reflects a growing trend among UK pubs seeking to differentiate themselves from establishments that "resemble soft play centres without the ball pit." While some welcome this shift, others view it as unwelcoming to families, creating a culture war in the pub industry.Lee Jones, landlord of the Brewers Arms in West Malvern, Worcestershire, reversed a previous child ban: "We're dog-friendly, child-friendly, adult-friendly. We're just friendly – we don't distinguish. Pubs are for the community and I don't see bans in the spirit of what we're here for." Jones reports that when children become rowdy, staff can address the issue with parents, though this is rarely needed.Stephen Boyd, who runs the Alma in south London, took a different approach after attempting to attract young families. He found families with children consumed disproportionate time and resources with special requests for diluted drinks, heated beverages, and customized meals, while adult customers waited longer for their orders."You just need a couple screaming, banging on a table or running up and down, and it dictates the whole atmosphere of the pub," Boyd says. "Parents would take massive umbrage if staff asked them to stop their children doing something." After implementing a child ban, he describes the change as "a fucking revelation" with staff retention improving and takings doubling.Despite the positive results, Boyd faced significant backlash: "I got a lot of online hate. Mainly from people who had never been to the pub but felt I was doing something morally hateful."Tom Stainer, chief executive of the Campaign for Real Ale, acknowledges the debate is "very live" but emphasizes: "But you do have to look at the responsibility of the parents in these situations, not just at the pubs. They're the ones responsible for making sure that their children behave."Financial considerations also drive some decisions. Mandy Keefe, landlady of the Wheel Inn in Ashford, banned children partly for behavioral reasons but also financial ones: "If a third of my Sunday customers were children eating from a reduced-rate child's menu and not drinking any alcohol, that wouldn't be financially viable."Across the UK, pubs are making individual decisions based on their specific circumstances, but as Johansen's experience demonstrates, it only takes one serious incident to settle the question for good.

The App Store Connect Transformation Apple has announced a significant update to its App Store Connect service, introducing over 100 new metrics and tools designed to help developers better understand and optimize their apps' performance across Apple's platforms. This overhaul comes at a critical time as the tech industry debates the future of app stores in the age of artificial intelligence. Expanded Metrics and Data Insights The updated App Store Connect now provides developers with comprehensive metrics across key areas including monetization, subscription data, and in-app purchase performance. Unlike third-party services that offer estimated data, Apple's metrics are based directly on the company's own data, providing more accurate insights into app performance. Among the new features are subscription reports that can be exported via an API, enabling developers to analyze their apps' performance offline or integrate Apple's data into their own systems. Developers can now gain deeper understanding of their users by analyzing behavior around download dates, sources, offer start dates, and other key engagement metrics. Competitive Analysis and Benchmarking Apple has introduced peer group benchmarks that allow developers to compare their performance against competitors in critical areas like download-to-paid conversions and proceeds per download. This feature provides valuable context for developers to assess their market position and identify opportunities for improvement. Apple emphasizes that it uses aggregated cohort data and differential privacy techniques to protect both user privacy and individual developer performance data, ensuring that insights can be gained without compromising sensitive information. Enhanced Data Filtering and Analytics Guide Developers can now apply up to seven filters simultaneously when viewing metrics in App Store Connect, allowing for more granular analysis of their app data. This enhanced filtering capability enables deeper dives into specific aspects of app performance. To support developers in making data-driven decisions, Apple has published a new App Store Analytics Guide in the Help section of App Store Connect. This comprehensive resource aims to help developers better understand the App Store's tools and features and develop effective strategies for app success. Strategic Timing Amid AI Evolution The timing of this App Store Connect overhaul is particularly noteworthy, as the industry witnesses rapid advancements in AI capabilities. There's growing speculation that AI agents could eventually replace traditional app stores, with some industry leaders suggesting that smartphone apps may become obsolete as AI-powered web services become more prevalent. Apple appears to be strategically positioning itself to strengthen its lucrative App Store ecosystem rather than allowing it to be disrupted by emerging technologies. The company is reportedly planning to announce an AI-powered Siri at its upcoming developer conference in June, which will be capable of completing tasks within apps, potentially bridging the gap between traditional apps and AI-powered services.

A humanitarian aid flotilla, dubbed the 'Nuestra America' or 'Our America' convoy, has arrived in Cuba to alleviate the island nation's struggles amid a severe US energy blockade. The first vessel, carrying approximately 30 people, along with essential supplies such as food, medicine, solar panels, and bicycles, docked in Havana, the capital city.The convoy set out from Mexico last week and is part of a broader effort to support Cuba, which has been facing widespread blackouts and an economic crisis due to the US embargo that has been in place for decades. The energy restrictions have significantly impacted Cuba, cutting off vital economic lifelines and contributing to the current crises.US President Donald Trump's administration has been vocal about its desire for regime change in Cuba, using energy restrictions as a tool to further degrade the Cuban economy. The US blockade has resulted in a nearly total ban on petroleum imports over the last three months, exacerbating the island's energy woes.Cuba's Deputy Minister of Energy and Mines, Argelio Abad Vigo, stated that the island, which produces only about 40 percent of the fuel it needs, has gone for three months without access to vital supplies of diesel, fuel oil, petrol, jet fuel, and liquefied petroleum gas. A February YouGov poll found that 46 percent of people in the US disapprove of the energy blockade, while 28 percent support it.The humanitarian aid effort, though described as 'a drop in an ocean of need,' represents a gesture of solidarity with the Cuban people. The convoy's arrival and the participation of over 650 participants from 33 countries who arrived on the island last weekend, demonstrate international support for Cuba during this challenging time.

The Gran Chaco forest in Argentina, spanning across parts of Argentina, Bolivia, Paraguay, and Brazil, is facing a critical threat from deforestation. Small farmers, enticed by the promise of quick money from selling timber, often contribute to this environmental degradation. However, a collaborative effort between conservationists, NGOs, and international organizations is underway to support small-scale landowners and Indigenous communities in establishing alternative income sources. This initiative aims to enable them to resist the pressures of agribusiness and the timber market. Jorge Luna, a 55-year-old farmer, has taken a significant step towards preserving his 40-hectare land in Chaco province. He rejected an offer to cut down the trees and instead embarked on a second career as a forest tourist guide with Fundación Rewilding Argentina, a non-profit organization working to restore parts of the Gran Chaco forest. Luna now rents out a small campsite to visitors and takes tourists on kayak tours along the Bermejito River. "At first, you didn’t give the plants value. It was a lack of knowledge of what they meant. Now, every leaf that sprouts has an added value," he says. Created in 2010 by Tompkins Conservation, Rewilding aims to protect vast tracts of territory and create economic opportunities for local communities while preserving the biosphere. The organization worked with 15 other organizations to convince the government of Chaco province to turn 128,000 hectares into the El Impenetrable national park, officially designated in 2014. Since then, Rewilding has established a network to support a budding tourism industry. It offers riverside glamping stays while promoting local and ancestral knowledge as possible sources of income. Women have returned to weaving and artisanal production, as well as providing home-cooked meals for visitors. According to Greenpeace, Argentina lost nearly 7 million hectares of native forest between 1998 and 2024, with most of it in the Gran Chaco. An estimated almost 120,000 hectares of forest were lost in northern Argentina in 2024, a 10% increase from the previous year. The primary causes of forest loss are the expansion of agriculture, mainly for intensive cattle ranching and genetically modified soya, and forest fires. The Gran Chaco forest also feeds the timber industry, particularly with the quebracho tree, which produces a tannin used in leather products, and carob trees. Environmental lawyers warn that the Gran Chaco could disappear within two decades if deforestation continues at its current pace. "The Chaco does not receive the same attention as the Amazon – few people even know it exists," says Enrique Viale, an Argentine environmental lawyer and activist. For conservation efforts to succeed, projects must be co-designed with the community, ensuring their long-term objectives are considered. Community empowerment, equal distribution of benefits, and capacity building are crucial factors. Mabel Figueroa, a local weaver, has resumed her craft since the national park opened, selling scarves, blankets, and ponchos to tourists. She raises sheep and dyes their wool with tree bark and forest plants, reviving an ancestral tradition.

A recent study has found that sperm deteriorates over time as it remains in the body, leading researchers to suggest that men who ejaculate more frequently may have better sperm quality.The study, which combined 115 human studies involving nearly 55,000 men and 56 studies on non-human species, found that the longer men went without sex, the more their sperm showed signs of DNA damage and oxidative stress, and the more tests rated the sperm as less viable and poorer swimmers.The World Health Organization (WHO) recommends men abstain from ejaculating for two to seven days before giving sperm for fertility tests or IVF, but the guidelines were designed to obtain the highest sperm count rather than prioritizing the best quality sperm.Dr. Krish Sanghvi, lead author of the study, said: "In men, the negative effects we found on sperm DNA damage and oxidative damage were large-ish, so we are confident that this is a biologically meaningful and important effect."The study's findings suggest that clinicians and couples should reconsider whether long abstinence is always good, as abstinence leads to deterioration in sperm quality.For couples trying to conceive naturally, a balance between quantity and quality needs to be struck, with abstaining for too long or too little potentially affecting sperm quality and quantity.Experts say that for assisted reproductive technology (ART) treatments, it's having the freshest, most healthy sperm that is probably more important, and that the two to seven days abstinence rule may not be as crucial when IVF treatment is taking place.

Europe is bracing for a potential energy crisis, with fuel rationing possible as early as April if the Strait of Hormuz, a critical passage for oil and gas supplies, remains closed. Shell's CEO, Wael Sawan, issued this stark warning at a major oil industry conference in Texas, highlighting the escalating risks to global energy supplies.The crisis, now in its fourth week, has already led to energy rationing in Asian countries and significant price hikes for jet fuel, which has doubled in price since the start of the conflict. Sawan predicts that diesel and petrol will come under pressure next, particularly as the summer driving season begins in the US and Europe.Oil prices have fluctuated, dipping back to about $100 a barrel on Wednesday after reaching highs of around $114 earlier in the week. These developments have raised concerns about the potential for a prolonged global economic recession if oil prices continue to rise, with some predictions suggesting they could hit $150 a barrel.Larry Fink, CEO of BlackRock, the world's largest asset manager, warned of profound implications for the world economy if the conflict continues to drive up oil prices. He outlined two possible scenarios: one where the conflict resolves quickly, allowing oil prices to return to pre-crisis levels of about $70 a barrel, and another where prices remain high for years, potentially leading to a stark and steep recession.Germany's economy minister, Katherina Reiche, also spoke at the conference, cautioning that energy supply scarcity could occur in late April or May if the conflict continues. She criticized Germany's decision to phase out nuclear energy and emphasized the need for greater imports of gas via super-chilled tankers from overseas.

Deal Overview Crusoe will purchase 12 gigawatt‑hours of Form Energy's 100‑hour iron‑air batteries. Delivery is scheduled for 2027, providing Crusoe with multi‑day backup capability. The agreement follows Form Energy's recent 30 GWh contract for Google in Minnesota, valued at roughly $1 billion. Redwood Materials will supply an additional 8 megawatts of power using repurposed EV batteries, augmenting Crusoe's existing 12 MW, 63 MWh microgrid installation. Financial and Market Implications Assuming a similar price per gigawatt‑hour as the Google deal (~$33 million/GWh), Crusoe's 12 GWh purchase could generate roughly $400 million in revenue for Form Energy, qualifying as “hundreds of millions” for the company. Form Energy is currently raising a $500 million funding round; the Crusoe contract adds tangible traction, supporting valuation uplift. Form has raised $1.4 billion to date, positioning it to scale production from its West Virginia factory. For Crusoe, the combined storage capacity (≈12 GWh + 63 MWh) reduces reliance on grid power, potentially lowering operating costs by an estimated 5‑7% annually for its data centers. Technology Insight Iron‑air batteries store energy via oxidation of iron pebbles; discharge produces rust and electricity, while charging reverses the reaction. The 100‑hour discharge rating enables multi‑day backup, a key differentiator from conventional lithium‑ion systems that typically last only a few hours. Redwood Materials focuses on second‑life EV batteries, extending their useful life and reducing material costs for large‑scale storage. Strategic Impact for Crusoe Enhanced resilience against grid outages and renewable intermittency, critical for high‑performance computing workloads. Demonstrates a commitment to sustainable operations, aligning with corporate ESG goals and attracting climate‑focused investors. Positions Crusoe as an early adopter of long‑duration storage, potentially setting an industry benchmark for data center energy strategy.
