Why Fans Are the Smart Summer Cooling ChoiceThe Guardian’s award‑winning tech journalist measured 16 fans and several evaporative coolers to see how they perform against a typical portable air‑conditioner that draws 1,000W (about 26p per hour). Fans in the test consumed between 8W and 60W, delivering a far lower electricity bill and carbon footprint while still moving enough air to make a noticeable temperature drop.Power Consumption Numbers Show Fans Beat Air‑ConditionersAirCraft Lume – 18W on top setting; could run 56 hours for the cost of one hour of air‑con.Dreo TurboCool misting fan 765S – 22W, best overall cooling performance.Devola desk fan – 12W, cheapest at £64.99.Shark FlexBreeze Pro Mist – 30W, premium misting option at £249.99.Swan Nordic evaporative cooler – 15W, lowest‑energy water‑based cooler at £69.Cooling Comfort Meets Carbon Savings for UK HouseholdsRunning a fan instead of an air‑conditioner can cut summer electricity use by up to 95 %, translating into lower bills and reduced greenhouse‑gas emissions. For a typical UK home, swapping a 1,000W air‑con for an 18W fan saves roughly £23 per month and avoids about 0.12 tCO₂ of emissions.What’s Next for Home Cooling in a Warming Climate?As heatwaves become more frequent, manufacturers are likely to focus on quieter, smarter fans with integrated sensors that adjust speed automatically. Expect more hybrid designs that combine low‑energy misting with airflow optimisation, giving consumers a wider menu of carbon‑friendly cooling solutions.

A Note on Chess and Professionals Back in the 1950s most top English players were amateurs, often civil servants or teachers, who competed in tournaments during their vacations. After the 1970s Fischer boom and English successes brought an influx of sponsors, chess professionals could earn a decent living, but the tide turned again during the 1990s. The breakup of the Soviet Union brought harder international competition, while Nigel Short’s world title defeat and the move to screen rather than print marketing drove sponsors away. A New Grandmaster: Harry Grieve Harry Grieve became England’s latest grandmaster on Tuesday when the 25-year-old, who was British champion in 2022 and helped CSC/Kingston finish second in this season’s UK 4NCL League, won first prize in Budapest with a 7/9 total.

The Lead The Museum of Homelessness in London is hosting an exhibition titled 'Criminal: An Untold Story of Homelessness, Resistance and Survival', which explores the criminalization of homeless people and nomadic communities over the last 400 years. The Exhibition's Powerful Message The exhibition features an installation by Romany Gypsy poet, performance artist, and journalist Gemma Lees, which includes a trim caravan with china decorated with Sun newspaper headlines criticizing Gypsy and Traveller encampments. The installation highlights the stark contrast between the cozy interior of the caravan and the harsh realities faced by nomadic communities. The History of Criminalization The exhibition takes visitors on a chronological journey through the history of criminalization, from the Egyptians Act of 1530 to the 2022 Police, Crime, Sentencing and Courts Act. It showcases how laws have been used to marginalize and criminalize homeless people and nomadic communities. The Impact on Homelessness London is currently facing a record high level of homelessness, with over 13,000 people sleeping rough in 2024-2025, a 10% increase from the previous year and a 63% rise over the past decade. The exhibition aims to raise awareness about the issue and provide a platform for discussion. The Future of Homelessness Support The Museum of Homelessness not only serves as a museum but also provides community support and acts as a cold weather shelter in winter. The exhibition 'Criminal' is a timely and powerful reminder of the need for better solutions to address homelessness and the criminalization of vulnerable communities.

The Timeless Allure of Tosca Gustav Mahler hated it, and its publisher was convinced it would be a commercial disaster. Critics complained it was mostly just 'noise' and predicted it would quickly be forgotten. But more than 125 years since Tosca's premiere in January 1900, Giacomo Puccini's fifth opera remains one of the most bankable in the business. The Opera's Turbulent Beginnings Puccini's work was initially met with skepticism. Mahler dismissed it as 'papal pageantry with continual chiming of bells.' The problem in 1900 was precisely that Puccini wove 'real-world' sounds of bells and screams, cannonfire and religious chant straight into his score. It was a groundbreaking example of an immersive soundscape, but for some, those sound effects were radically out of place in an operatic work of art. The Data Behind Tosca's Success Over 125 years since its premiere, Tosca remains a popular opera. It is known for its melodic appeal and gripping plot. The opera has been performed in numerous productions worldwide. The Impact of Tosca on Opera Tosca's enduring appeal lies in its combination of overwhelming melodic appeal and a sex-and-death nail-biter of a plot. US director Ted Huffman suggests that 'It's also a study of evil, which we find really entertaining in a horrible way.' The opera's themes of state violence and resistance are particularly relevant today. The Future of Tosca Productions Despite its popularity, there have been few bold reimaginings of Tosca. Most productions stick to the traditional setting in Rome. However, Huffman's new production at Glyndebourne, inspired by 1940s neorealist Italian film, offers a fresh take on the classic opera. The production explores realism and its relevance to today's world.

The Birth of a Classic The Mekons and Gang of Four emerged from the same fine art course at Leeds University. After being inspired by the Clash and the Sex Pistols, the Mekons formed and recorded their first single, 'Never Been in a Riot', on a two-track tape recorder in a living room. The Making of 'Where Were You?' For their song 'Where Were You?', Bob Last from the Fast Product label helped them record at Spaceward in Cambridge. The song came together quickly with Kevin Lycett strumming two chords, Tom playing a choppy counter-melody, and Jon on drums. Mark White wrote the lyrics, and Andy Corrigan sang them. The Impact of 'Where Were You?' 'Where Were You?' became a huge success, selling over 27,000 copies and receiving significant airplay from John Peel. The song gained even more popularity when David Bowie compared the Mekons to T. Rex on a Radio 1 programme. The Legacy of 'Where Were You?' The song has remained a classic, with the Mekons still playing it live almost 50 years later. The song's lyrics, influenced by Buzzcocks' Pete Shelley, deal with themes of loneliness and feminism. The Mekons' decision to include women in the band and their anti-macho approach to music set them apart from other rock bands at the time. The Song's Enduring Influence 'Where Were You?' continues to have an impact, with the song being used in an advert for Honda's Acura cars and generating a substantial amount of money for the band. The Mekons' story serves as a testament to the power of creativity and perseverance in the music industry.

The Masterpiece of John Woo The title of this 1990 John Woo extravaganza might lead the uninitiated to expect a chillingly focused, targeted assassination. Actually, there are innumerable bullets and innumerable heads in this over-the-top gonzo spectacle. It is a crime thriller, a wartime action film set in Vietnam, but it offers something other than the usual Hollywood perspective; it is a parable of greed comparable to The Treasure of the Sierra Madre, and even a kind of romantic melodrama. The Symbolic Bullet There is, however, one key bullet in a head, a literal bullet lodged in the skull of someone who achieves a macabre zombie-like semi-survival, the bullet being symbolic of the way violence takes root in the brain, dehumanising its victim. The final “boardroom” scene disclosing this image is toweringly mad and strange. Yet in this movie, as in so many other Woo films, we can see how the director counterintuitively uses sad music – harmonica, woodwind – over grisly, brutal action sequences, as if what he wants us to register is not the violence or the shock but just how poignantly futile and pathetic it all is. The Plot Unfolds The setting is – initially – late 60s Hong Kong; Tony Leung plays Ben, a young guy getting married to his sweetheart Jane (Fennie Yuen), and on hand are his buddies Frank (Jacky Cheung) and Paul (Waise Lee). This trio are involved in a gang war with a rival mob who corner Frank when he has gone to get cash from the local moneylender to pay for the wedding. The confrontation ends in violence and, simply to get away and avoid the heat – Woo has a cameo as a police inspector – the three guys accept a crooked job from a local gang boss smuggling contraband pharmaceuticals in Vietnam. The Climax In Saigon, all their plans explode in pure anarchy; they are at first arrested under suspicion of working for the Vietcong, then upgrade their strategy to cynical arms smuggling for the North Vietnamese, and stealing the gold belonging to the local wiseguy who was supposed to be distributing their drugs. They make contact with a worldly fixer called Luke (Simon Yam), who has a Catherine Deneuve poster in his apartment, and also gallantly undertake to rescue a Hong Kong singer Sally (Yolinda Yam), who has been trafficked to Vietnam to sell sex. They end up on the spectacular field of battle itself (with helicopters, explosions, burning villages), where Paul, increasingly obsessed with the gold, finds himself at a key moment at mortal risk of detection if he cannot keep the wounded Frank quiet, whose cries of pain might alert the enemy to their position. The Legacy It’s an extraordinary, uninhibited barnstormer from Woo, who takes us from regular, domestic crime to military chaos with confidence and sweep. One moment, in which someone stands in front of a tank, even appears to echo the Tiananmen Square protests. No one else could have made it. The Release Bullet in the Head is in UK cinemas from 1 June, and on 4K UHD and Blu-ray from 22 June.

The Lead Meena Kandasamy's novel "Fieldwork As a Sex Object" tackles the terrifying reality of deepfake technology and its use in online harassment, particularly targeting women in India's complex digital landscape. Through protagonist Amy Chaturvedi, the novel explores how fabricated content can destroy lives and how internet trolls exploit such content for misogynistic and political purposes. The Digital Hell of Indian Internet Culture The novel portrays India's internet as a particularly toxic environment, far exceeding the toxicity of Western platforms like X and Facebook. Kandasamy captures a world where caste, religion, and political extremism intersect with misogyny to create a dangerous space for women. The author describes how algorithms, far-right government influence, and societal tensions combine to create a digital hellscape where women are systematically targeted and harassed. The Deepfake Crisis and Its Victims The central plot revolves around Amy Chaturvedi, a privileged student activist living in London, who becomes the victim of a deepfake sex tape. Despite her sexual liberation and experimentation, Amy must confront a world that immediately judges and shames her based on the fabricated content. The novel explores how such digital violations can be used as weapons, not just for humiliation but also for political and social control. The Anatomy of Online Trolls Kandasamy provides a sharp, humorous, yet critical examination of the Indian internet troll, exposing their motivations, insecurities, and political alliances. The author portrays trolls as a "disparate bunch of Nazi-loving, Islamophobic vegetarian dicks" who use anonymity to spread hate, promote extremist ideologies, and attack those who challenge their worldview. The novel reveals how these trolls operate in coordinated campaigns to silence dissenting voices, particularly women and minorities. Literary Merits and Political Commentary As one of India's most outspoken writers, Kandasamy blends personal narrative with political commentary, creating a work that is both entertaining and thought-provoking. While the reviewer notes some stylistic choices that could be refined—particularly the Marxist theoretical framework and excessive internet jargon—the novel's power lies in its unflinching portrayal of online misogyny and its intersection with political extremism. The author's willingness to "not pull any punches" makes her a vital voice in contemporary Indian literature. The Future of Digital Rights and Literature "Fieldwork As a Sex Object" arrives at a critical moment when deepfake technology is becoming increasingly sophisticated and accessible. The novel serves as both a warning and a call to action, highlighting the urgent need for better legal protections and digital literacy. As internet culture continues to evolve, works like Kandasamy's will play an essential role in shaping public discourse about technology, power, and gender in the digital age.

The AI-Driven Economic Surge Taiwan's economy is booming, with a growth rate that would be the envy of any country. The AI boom sweeping Taiwan has made it an exciting time to work in tech, particularly in the semiconductor industry, which produces about 90 percent of the most advanced chips used to power leading AI models. The Semiconductor Industry's Dominance Taiwan is a semiconductor powerhouse, with Taiwan Semiconductor Manufacturing Company (TSMC) accounting for more than 40 percent of the value of the island's stock market. Semiconductors alone account for more than 20 percent of Taiwan's GDP. The Uneven Distribution of Benefits Despite the impressive economic growth, concerns are rising about the uneven distribution of benefits. Many industries unrelated to tech do not seem to be feeling the benefits, with some individuals experiencing stagnant pay and rising living costs. The semiconductor industry employs only about 300,000 people in a workforce of 11 million. The Risk of a 'Dual Society' Economists warn that Taiwan's economic model has left it at risk of becoming a 'dual society' where tech sweeps up talent, funding, and resources at the expense of other industries. The wealth divide has grown over the decades, with Taiwan's Gini coefficient increasing from 0.308 in 1980 to 0.341 in 2024. The Future Outlook As Taiwan's economy continues to grow, the government faces challenges in addressing the uneven distribution of benefits and ensuring that the growth is inclusive and sustainable. The country's reliance on a single industry for growth marks a shift from the Asian Tiger era, when Taiwan's economy was driven by hundreds of thousands of small and medium-sized enterprises.

The team's manager, Mikel Arteta, has seen a considerable boost in his professional status, making him a sought-after candidate for top clubs and potentially the England national team. Arteta's Elevated Status Arteta's relationship with the club has transformed, and his ability to lead Arsenal to a Champions League final has solidified his position as an elite coach. This newfound status could make it challenging for Arsenal to retain him, as he may attract interest from other top clubs, including PSG and Spain's big two. The Impact of the Premier League Title The Premier League title has brought a sense of liberation to Arsenal, allowing them to approach the Champions League final without the weight of anxiety that previously defined their performances. This shift in dynamics could play a crucial role in determining the outcome of the final against PSG. The Challenges Ahead PSG, with their strong attacking personnel, including Ousmane Dembélé, Désiré Doué, and Khvicha Kvaratskhelia, will be favored to win the final. However, Arsenal's newfound confidence and Arteta's elevated status could make the match more competitive than expected. The Future Outlook A win in the Champions League final would be a historic moment for Arsenal, marking a significant milestone in the club's history. It would also cement Arteta's position as a top-tier manager, potentially paving the way for future successes and opportunities, including the possibility of managing the England national team.
