When Corentin Roudaut arrived in Paris a decade ago, he swapped his student‑era bike for a car, daunted by the city’s traffic and lack of cyclist protection. After a protected lane opened on Boulevard Voltaire in the 11th arrondissement, he reclaimed his two‑wheel commute and now volunteers with the cycling advocacy group Paris en Selle, witnessing a city that has shed its car‑centric image.Roudaut notes that the shift “started slowly but really accelerated in the last ten years,” with a growing network of bike routes that is becoming safe and nearly complete in many districts.Mayor Anne Hidalgo’s 12‑year agenda reshaped Paris’s urban fabric. Since taking office in 2014, her administration planted 155,000 trees, created several hundred kilometres of segregated bike lanes, pedestrianised 300 school streets, and banned cars from the banks of the Seine. Former parking spaces have been turned into green plazas and café terraces, reducing the risk of children being hit while walking to school.As Hidalgo departs on Sunday, her legacy is touted as a blueprint for progressive European cities, especially as some national governments retreat from green initiatives.Nevertheless, the reforms have sparked pushback. Motorists object to the loss of road space, and recent referendums on higher parking charges for SUVs and further school‑street pedestrianisation suffered low voter turnouts. Right‑wing mayoral candidate Rachida Dati described the new public‑space regime as “anxiety‑inducing,” though she stopped short of promising a reversal.In a candid interview, Hidalgo described the Seine‑bank pedestrianisation as “a tough battle” that, once won, left residents reluctant to revert to car traffic. She highlighted a generation of children who have never known cars on those riverbanks, prompting awe‑filled reactions from visitors.Urban scholars attribute the rapid change to Paris’s tight administrative boundaries, which limit suburban influence on city transport decisions, and to groundwork laid by previous mayors. Yet they stress that political courage was essential to implement measures that inconvenienced drivers while delivering social and environmental benefits.Environmental epidemiologist Audrey de Nazelle of Imperial College London, a Paris native, praised the transformation as “fabulous” and warned that many cities lack the bravery to pursue similar legacies.A recent report placed Paris among 19 global cities that cut two major toxic air pollutants between 2010 and 2024. While Brussels and Warsaw saw faster declines in fine‑particle matter, London outpaced Paris in reducing nitrogen‑dioxide levels.By contrast, Berlin—despite opening a new inner‑city motorway and scrapping 30 km/h speed limits on key streets—still records a higher share of cyclists than Paris.Transport researcher Giulio Mattioli argues that Paris simply needed to add bike lanes to unlock latent demand, noting that the city started from a lower baseline but quickly caught up with peers.However, the transformation remains uneven. The extensive suburbs continue to be dominated by cars, hemmed in by the 35 km Boulevard Périphérique ring road. Analyst Jean‑Louis Missika of think‑tank Terra Nova stresses that “as long as this motorway encircles Paris, the Greater Paris metropolis will remain an administrative construct devoid of urban reality.” He calls for dismantling or repurposing the ring road to achieve a truly post‑car metropolis.

Cambodia has taken a significant step in its fight against cybercrime by approving a new law targeting scam centers accused of defrauding foreigners of billions of dollars. The law, which aims to enhance the country's 'cleaning operation' against these illicit operations, imposes punishments of two to five years in prison and fines of up to $125,000 for those convicted of online scams.The legislation, which will now go to Cambodia's king for a final signature, also outlines penalties for money laundering, gathering victims' data, or recruiting scammers. Ringleaders of scam centers that engage in human trafficking, detentions, and torture will face prison sentences of up to 20 years and fines of up to $500,000.The passage of the law comes amid widespread condemnation from rights groups and sanctions by governments around the world, with Cambodia accused of being a hotbed of cyberscams. The US Department of State has previously stated that 'official complicity, including at senior levels, inhibited effective law enforcement action against trafficking crimes' in Cambodia, which has denied these allegations.The new law is seen as a significant effort by Cambodia to combat the rise of online fraud, romance, and cryptocurrency scams. Several countries have enacted anti-cyberscam laws to address this issue, with con artists in Singapore facing 24 strokes of the cane in serious cases.Justice Minister Keut Rith emphasized that the law is 'strict like the fishing net' and aims to ensure that online scams do not return to Cambodia. The law is expected to send a strong message to cyberscammers that Cambodia is not a place to conduct scams, and it will serve the interests of the Cambodian nation and people.

Peptides are short chains of amino acids that naturally occur in the body, acting as hormones such as insulin, oxytocin and vasopressin, or as fragments released during protein digestion.In recent years, a wave of interest has turned these molecules into purported therapeutic agents for everything from weight loss to anti‑ageing and tissue repair. Prescription drugs like semaglutide (Wegovy) and tirzepatide (Mounjaro) are synthetic peptides that have undergone rigorous clinical testing and are approved for specific medical uses.However, a large portion of the market consists of unregulated, experimental peptides sold for self‑administration. These products often bypass the strict approval processes required for medicines, raising serious safety concerns.Who is using these products? Initially confined to a niche of powerlifters and bodybuilders in the 2010s, the audience has expanded dramatically. Influential figures such as podcaster Joe Rogan have promoted combinations like the “Wolverine stack” (BPC‑157 and TB‑500) for injury recovery, while other compounds—CJC‑1295, MK‑677, ipamorelin, and GHK‑Cu—are marketed for muscle growth and anti‑ageing. Social media platforms are now flooded with instructions on purchasing and injecting these substances.Scientific backing is scant. Reviews of the literature reveal that most experimental peptides have only been tested in animal or cell models. For example, BPC‑157 shows promise for tendon and muscle repair in pre‑clinical studies, but no randomized human trials have validated these effects. Similarly, TB‑4 and its synthetic analogue TB‑500 have demonstrated limited blood‑vessel formation in laboratory settings, yet human data are absent and both are listed as prohibited substances by the World Anti‑Doping Agency.Researchers also highlight a critical knowledge gap: dosage, frequency and treatment duration remain undefined, making self‑administration a gamble.Legal landscape in the UK is clear that peptides not classified as medicines fall outside the Medicines and Healthcare products Regulatory Agency’s (MHRA) remit. If a seller makes medicinal claims, the product must hold a marketing authorisation under the Human Medicines Regulations 2012. The MHRA warns that labeling items as “research use only” does not shield vendors from enforcement when evidence shows the products are intended for human consumption.Health risks are multi‑fold. Experts caution that benefits observed in animal studies do not guarantee safety in humans. Contamination with harmful impurities or bacterial endotoxins can trigger severe reactions, including septic shock. Injecting excess natural peptides may disrupt the body’s tightly regulated hormonal balance, potentially affecting multiple physiological pathways.There is also theoretical concern that augmenting peptide levels could accelerate tumour growth, as some cancers over‑express certain peptide pathways. While no direct cases have been documented, the possibility underscores the need for caution.Additional dangers include improper injection techniques (e.g., air embolism), unknown interactions with existing medications, and the lack of systematic monitoring of long‑term effects. As one researcher put it, “If something goes wrong, users may never notice until irreversible damage has occurred.”

Science is often seen as a dry and serious field, but does it have to be? A recent study published in Proceedings of the Royal Society B found that scientists deliver an average of only 1.6 jokes per presentation, with 66% generating only polite chuckles.The findings confirm previous research, including a randomized clinical trial conducted over 20 years ago by Timandra Harkness and Helen Pilcher under the guise of the Comedy Research Project. The study found that laughter levels failed to reach statistical significance, even when scientists attempted to incorporate humor into their talks.However, research suggests that humor can be an effective tool in science communication. A 2025 study called Wit Meets Wisdom found that humor can boost credibility and likability, making researchers seem more trustworthy and their findings less likely to be disputed.Helen Pilcher, a science writer and author, argues that scientists should not be afraid to adopt a more playful tone when communicating their research. By incorporating humor, scientists can build cohesion and foster a sense of shared perspective with their audience.Pilcher suggests that scientists can use humor to make their research more engaging and memorable, without having to convert it into standup comedy. By doing so, scientists can make their research more accessible and enjoyable for a wider audience.

AI‑Driven Power Race The AI boom is prompting the biggest wave of power‑infrastructure investment since the early days of cloud computing. Companies are scrambling to lock in natural‑gas supplies and build on‑site generators, a move that could reshape electricity markets in the southern United States. Scale of the Projects Microsoft is partnering with Chevron and Engine No. 1 to construct a natural‑gas plant in West Texas that could reach 5 GW of capacity. Google has confirmed a collaboration with Crusoe for a 933 MW plant in North Texas. Meta is adding seven more plants to its Hyperion data‑center complex in Louisiana, bringing total on‑site capacity to 7.46 GW—enough, the company notes, to power the entire state of South Dakota. Combined, these projects exceed 13 GW, roughly equivalent to the average electricity demand of a mid‑size U.S. state. Supply Constraints and Cost Pressures Wood Mackenzie warns that turbine prices have surged 195% versus 2019 levels. If a 2020 turbine cost $1 million, the same unit now costs about $2.95 million, inflating the equipment share of a plant’s budget from 20% to up to 30%. The consultancy also notes a six‑year lead time for turbine delivery, meaning new orders cannot be placed until 2028. This bottleneck could delay the rollout of additional capacity precisely when AI workloads are accelerating. Resource Availability and Market Risks The U.S. Geological Survey estimates that a single gas‑rich region holds enough supply to power the entire United States for 10 months. While abundant, production growth in the three leading shale basins—responsible for three‑quarters of U.S. output—has slowed, tightening the long‑term outlook. Natural gas accounts for about 40% of U.S. electricity generation (EIA). Consequently, any spike in gas prices reverberates through wholesale electricity markets, raising the cost of power for all consumers, not just data‑center operators. Strategic Risks for Tech Companies Behind‑the‑meter gas plants allow firms to claim “self‑supply,” but they merely shift demand from the public grid to the gas grid, potentially driving up wholesale gas prices. Industrial users—petrochemical plants, fertilizer manufacturers—cannot easily substitute gas with renewables, so they may push back against large‑scale data‑center consumption. Extreme weather, such as the 2021 Texas freeze, can curtail wellhead output, forcing a choice between keeping AI workloads online or supplying heat to households. In sum, the AI‑driven rush for natural‑gas power plants highlights a fundamental physical constraint: the digital economy still depends on finite, market‑sensitive energy resources. Betting heavily on a commodity that can swing dramatically in price may prove costly if AI growth plateaus or if gas supply tightens.

The ongoing war in Iran has ignited a fresh oil supply shock, sending crude prices soaring and rippling through economies worldwide. Analysts note that the conflict’s persistence is tightening global oil flows, prompting immediate spikes in gasoline, diesel, and jet fuel costs. Energy traders report that the heightened uncertainty has amplified market volatility, with benchmark crude benchmarks climbing to levels not seen in months. The price surge is pressuring both consumers and businesses, as higher fuel costs translate into increased transportation expenses and broader inflationary pressures. Governments and central banks are now monitoring the situation closely, aware that sustained higher oil prices could erode economic growth and strain household budgets, especially in regions heavily dependent on imported energy. While the full economic impact remains to be quantified, the consensus among experts is clear: the prolonged Iran war is reshaping the global energy landscape, underscoring the fragility of supply chains and the need for diversified energy strategies.

Liverpool's season has reached a critical juncture, with five matches in 16 days set to determine the fate of manager Arne Slot's vision for the team. The Reds face a daunting schedule, including cup quarter-finals against Manchester City and Paris Saint-Germain, as they seek to salvage a disappointing campaign.The team's inconsistent form has raised concerns about their ability to secure Champions League qualification, a crucial aspect of the club's business model. Liverpool's recent performances have been marred by defeats to Wolves and Brighton, highlighting issues with fitness levels, efficiency in front of goal, and organisation.The return of Alexander Isak to team training could provide a much-needed boost, but the striker will have to prove himself upon his return to competitive action. Isak's partnership with Florian Wirtz has been limited due to injuries, and the duo will need to deliver to justify Liverpool's £125m investment in the striker.Liverpool's hierarchy, including owner Fenway Sports Group and sporting director Richard Hughes, are aware of the challenges faced by Slot this season, including the death of Diogo Jota and injuries that have hindered the team's performance. However, the club's supporters are growing increasingly disillusioned, with ticket price increases and a record revenue of £703m failing to translate to on-field success.A positive note was struck by Jürgen Klopp's return to Liverpool, which drew a sellout crowd of 60,482 and raised over £1m for the LFC Foundation. Nevertheless, the adoration for Klopp contrasted with the frostiness towards Slot, highlighting the challenges faced by the current manager in reviving the team's fortunes.

According to a new United Nations Food and Agriculture Organization (FAO) briefing, the global food commodity price index climbed 2.4% in March, marking the second straight monthly increase and the first rise in five months for the broader basket of grains, meat, dairy, vegetable oils and sugar.The surge is largely attributed to the escalating conflict in the Middle East, which has pushed up energy prices and freight rates worldwide. The report highlighted that vegetable oil prices jumped 5% and sugar rose 7% during the month.Analysts warn that the war could trigger a broader wave of food inflation, as higher fuel, fertiliser and electricity costs increase the expense of transporting, processing and cooking food. About one‑third of global fertiliser production passes through the Strait of Hormuz, a key shipping lane that has been effectively closed since hostilities began.UN projections suggest that, if the crisis endures, global food prices could be 15%–20% higher in the first half of 2026 than pre‑conflict levels. The FAO noted that “price indices across all commodity groups rose to varying degrees, reflecting both market fundamentals and responses to higher energy prices linked to the conflict escalation in the Near East.”Specific commodity trends showed global wheat prices up 4.3% in March, driven by deteriorating crop conditions and drought concerns in the United States, as well as reduced planting in Australia due to soaring fertiliser costs. Better weather in Europe and strong export competition provided some offset.In the United Kingdom, the Food and Drink Federation – representing 12,000 manufacturers – now forecasts a **minimum 9% rise in food prices by the end of 2026**, a sharp increase from the 3.2% forecast made before the Middle East conflict. This outlook assumes the Strait of Hormuz reopens within weeks and that major energy facilities return to normal within a year – both uncertain outcomes.British producers are already feeling the pressure. The British Tomato Growers’ Association warned that consumers could see higher prices for tomatoes, peppers and cucumbers within six weeks as gas‑heated glasshouses become more expensive to run.Chancellor Rachel Reeves recently met with leaders of major retailers—including Tesco, Sainsbury’s, Morrisons, Marks & Spencer, Aldi and Lidl—to discuss measures that could ease the cost‑of‑living squeeze and strengthen supply chains.Nevertheless, a Bank of England survey of over 2,000 chief financial officers revealed that firms expect to raise their prices by an average of 3.7% over the next year, up from 3.4% in February. Expectations for overall economy‑wide inflation also rose from 3% to 3.5%.

The latest Supergirl trailer has generated significant buzz, hinting at a fresh take on the iconic DC character. Director Craig Gillespie has revealed that the film will feature a nine-world structure and a considerable amount of planet-hopping, setting it apart from previous superhero films.Building on the success of James Gunn's Superman, which offered a unique twist on the Man of Steel, Milly Alcock's Kara Zor-El is poised to bring a new level of excitement to the DC Universe. The trailer showcases Alcock's character navigating alien landscapes and battling foes with a swagger reminiscent of a cosmic gunslinger.What sets this film apart is its exploration of Kara's vulnerabilities when she's away from Earth's yellow sun. In the comic book series Supergirl: Woman of Tomorrow, Kara encounters a world under a green sun that drains her powers, making her physically ill. This element could add a layer of complexity to the story, as Kara searches for an antidote across multiple planets.The film's setup has a video-game-like quality, with Kara's power levels potentially fluctuating as she navigates different environments. This mechanic could sharpen the drama and create a sense of tension, as Kara faces challenges that test her abilities.While there are risks involved in this bold new direction, the prospect of seeing a more vulnerable and dynamic Supergirl on the big screen is an intriguing one. As the DC Universe continues to evolve, fans are eager to see how this new take on a classic character will unfold.
