A remarkable cactus species in eastern Brazil has evolved a unique method to attract bats for pollination. Coleocephalocereus goebelianus grows a fuzzy structure, known as a cephalium, near its flowers. This unusual body part acts as an acoustic beacon, focusing the high-pitched squeaks made by bats and helping them navigate towards the flower.Bats use echolocation to navigate and find objects in the dark by emitting high-frequency sounds, which are beyond human hearing. The cephalium's dense structure may also help reduce background noise, making the bats' echolocation clearer.The cactus's tall stature above surrounding plants amplifies its acoustics, making it easier for bats to locate the flower. This adaptation is crucial for the cactus's pollination, as it blooms at night and relies on bats as pollinators.Similar adaptations can be seen in carnivorous pitcher plants, which use curved dish-like openings to reflect bat calls and help them find the pitchers. In these cases, the bats roost inside the pitchers, and their dung fertilizes the plant.This unique evolutionary strategy highlights the fascinating ways in which plants have adapted to their environments to ensure pollination and survival.

The International Monetary Fund (IMF) has issued a warning that a closure of the Strait of Hormuz could lead to a major energy crisis. The strait, located between Iran and Oman, is a critical passage for global oil shipments, making it a vital artery for the world's energy supplies.A disruption in this region could have significant implications for the global economy, potentially leading to higher oil prices and increased volatility in energy markets. The IMF's warning underscores the importance of maintaining stability in this critical region.

After a 90‑year blackout, MGM’s 1932 melodrama Letty Lynton is set for its first legal public screening. The film, starring Hollywood icon Joan Crawford, was withdrawn in 1937 following a plagiarism lawsuit and pressure from the Hays Office, which deemed its risqué themes “unfit for adaptation”.The controversy began when MGM attempted to acquire the rights to the Broadway hit Dishonored Lady, a play notorious for its depictions of booze, drugs and sexual intrigue. After the playwrights demanded $30,000—a sum the studio balked at—MGM settled for the cheaper novel by Marie Belloc Lowndes for $3,500. The resulting film, inspired by the 1857 murder trial of Scottish socialite Madeleine Smith, shocked contemporary censors with scenes such as Crawford’s character watching her ex‑lover sip poisoned champagne.Legal battles intensified when playwrights Edward Sheldon and Margaret Ayer Barnes sued MGM for plagiarism, alleging the movie copied their work rather than the novel. The protracted case forced MGM to pull the film from circulation in 1937, and a year later Crawford herself was labeled “box‑office poison”. Yet both the actress and the film survived, resurfacing in cultural memory through fashion and later adaptations.Beyond cinema, Letty Lynton left an indelible mark on 1930s style. Costume designer Adrian created a white organdy dress with exaggerated sleeves for Crawford; the design was mass‑produced for Macy’s and sparked a nationwide craze. Edith Head later called the dress “cinema’s single biggest influence on fashion”.The film’s revival is largely credited to Crawford’s grandson, Casey LaLonde. In an Instagram post, he announced that the play’s copyright would expire on 31 December 2025, clearing the legal path for a public showing. Warner Bros., which now holds the rights to many pre‑1986 MGM titles, restored the picture in 4K and arranged for its debut at the TCM Film Festival in Los Angeles on 1 May 2026. The movie will also be issued on Blu‑ray and DVD through the Warner Archive.LaLonde thanked Warner Bros. and library historian George Feltenstein for making the restoration possible, noting that without their effort “we wouldn’t have this fabulous film to see again on big and small screens.”Fans of classic Hollywood can finally experience a piece of cinema history that was once deemed too daring for the silver screen, offering a fresh look at Joan Crawford’s daring performance and the era’s bold storytelling.

Leeds, the largest European city still without a mass‑transit system, may finally see a tram line – but not before the late 2030s. The latest West Yorkshire Mass Transit plan, championed by combined‑authority mayor Tracy Brabin, received a fresh £200 million in development funding, part of a broader £2.1 billion allocation for the region.City council leader James Lewis, who began his career on a 1993 work‑experience placement with the council’s highways department, says the new scheme differs from past attempts. Instead of squeezing trams onto existing bus routes, the proposal envisions a dedicated line that could “float over or under the M621 motorway, similar to the Docklands Light Railway,” linking the White Rose shopping centre, Elland Road stadium, Leeds railway station and St James’s Hospital.The Treasury’s independent review, however, forced the government to demand a fresh business case that proves the need for trams rather than buses. This procedural hurdle has added roughly two years to the timetable, pushing the projected opening into the late 2030s. Brabin acknowledges the setback, noting critics now claim the project is effectively “cancelled,” but she insists the work is merely delayed, not abandoned.Leeds’ transport woes date back to the removal of its historic double‑deck tram network in 1959 and the construction of the M621, which many locals blame for isolating the city’s south side. A 2025 Treasury review warned that previous “Supertram” proposals failed because they could not demonstrate sufficient value for money, leading to the withdrawal of funding in 2005 and the abandonment of a trolley‑bus plan in 2016.Supporters argue the tram is essential for unlocking massive regeneration. Leeds United investor Pete Lowy predicts the line could catalyse up to £1 billion of investment, including 2,500 new homes, retail and leisure space, and a 15,000‑seat stadium expansion. Northern Powerhouse Partnership chief executive Henri Murison points to the emerging South Gateway development in Bradford as evidence that transport‑led investment is already materialising.Critics remain sceptical. Leeds University transport professor Greg Marsden questions how an 18‑year‑long project can still be justified, while local residents voice doubts that a tram can ever be built in a city they consider “not big enough.” Tom Forth, co‑founder of data‑city firm Information Group, blames centralised decision‑making in London, arguing that devolved funding would accelerate delivery.In the meantime, the council is focusing on improving bus services, which will come under public control in 2027. Centre for Cities analyst Rob Johnson notes that increasing bus frequencies could immediately benefit the 390,000 residents currently poorly connected, potentially delivering more mobility gains than a tram in the short term.Nevertheless, Brabin maintains that trams are “more attractive, carry more passengers, and generate more jobs and growth” than buses, and she reaffirms her promise: “I promised a tram, and a tram is what we’re going to get.” The pledge to have “spades in the ground” by 2028 for preparatory works remains on the table, even as the project navigates the Treasury’s stringent process.

The new Apple TV series 'Margo's Got Money Troubles' marks a significant milestone in Michelle Pfeiffer's career renaissance. The show, a comedy-drama created by David E Kelley, is based on the 2024 bestselling novel by Rufi Thorpe and directed by Dearbhla Walsh.Elle Fanning stars as Margo, a young woman who becomes pregnant after having a relationship with her English professor. Her mother, Shyanne, played by Pfeiffer, also got pregnant at a young age and has been struggling to make ends meet. The series explores their complex relationship and the challenges they face.Pfeiffer delivers a powerful performance, particularly in a scene where she expresses her grief and disappointment at Margo's pregnancy. “Will I love him? Of course. Just as I loved you from the moment you were born … But this life as you know it – this life that you never got to know – is over. I can’t rejoice in that.” This scene showcases Pfeiffer's talent and adds depth to the show.However, the series remains a David E Kelley production, which means it stays light and firmly on the side of the angels. The drama avoids exploring darker themes in depth, making it a cosy commentary on family and relationships.The show also stars Greg Kinnear as an Episcopalian minister and Nicole Kidman as a former wrestler turned lawyer. Despite its talented cast, the series could have been more impactful with a more nuanced approach to its themes.'Margo's Got Money Troubles' is now available on Apple TV.

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.

New research from the Institute for Fiscal Studies (IFS) shows that the Help to Buy mortgage initiatives launched by the Conservative‑Lib Dem coalition in 2013 mainly benefited higher‑income households, rather than the intended first‑time, lower‑income buyers.The policy comprised two components: a taxpayer‑backed loan that reduced required deposits, and a mortgage guarantee scheme that covered part of lenders’ losses on high loan‑to‑value mortgages. Both applied to properties priced up to £600,000 and, by the 2014‑15 fiscal year, accounted for roughly one‑fifth of first‑time buyer transactions.Using a novel methodology that combined survey responses with local property price data, the IFS concluded that the bulk of the advantage accrued to wealthier purchasers—particularly those outside London and the south‑east, where homes are comparatively cheaper. These buyers were likely to secure a property eventually, even without the scheme.Bee Boileau, a research economist at the IFS and co‑author of the briefing, warned that while Help to Buy can theoretically assist newcomers onto the housing ladder, it also risks inflating prices and shifting loan risk onto the public sector. “Our research indicates that the Help to Buy schemes introduced in 2013 had the largest impact – in terms of making more homes affordable – on higher‑income households,” she said.The study notes that the mortgage guarantee scheme had “limited effects on affordability” because borrowers remained constrained by income‑based borrowing caps. Conversely, the loan scheme proved more influential for most households, yet its impact was muted by its restriction to new‑build properties.Both components appear to have had little effect on social mobility. Boileau suggested that future governments aiming to reduce inequality should target assistance at lower‑income families, acknowledging that such a shift would increase taxpayer exposure to loan risk.Critics have long argued that Help to Buy inflated house prices without expanding supply. A 2022 House of Lords built‑environment committee report echoed this view, recommending that funds be redirected toward increasing housing construction.The mortgage guarantee element was revived in 2021 and made permanent by the Labour government last year to preserve access to 95% mortgages. In response, Conservative housing secretary James Cleverly defended the legacy schemes, claiming they enabled “many thousands of people” to achieve homeownership, even as he warned that Labour policies were making the market harder for first‑time buyers.

The humanitarian situation in Sudan has taken a devastating turn as the country prepares to mark the third anniversary of the brutal conflict between the army and paramilitaries. Nearly 700 civilians have been killed in drone strikes in Sudan since the beginning of 2026, according to the United Nations.The increasing use of drones in the conflict has been noted by the UN's humanitarian chief Tom Fletcher, who warned that the world has "failed to meet the test of Sudan". The conflict has disrupted life across Sudan, particularly in the southern Kordofan region and areas of the west controlled by the paramilitary Rapid Support Forces (RSF).Doctors Without Borders reported two more deaths following drone strikes launched by the Sudanese army in the Darfur region, and treated 56 people wounded in the attack. The UN Children's Fund (UNICEF) said that drones were "responsible for nearly 80 percent" of the at least 245 children reported killed or injured during the first three months of the year.The UN's World Food Programme (WFP) warned that the situation is being "dangerously compounded" by the war in the Middle East, which has disrupted supply chains for aid groups. The US-Israeli war on Iran has forced aid groups to use costlier, more time-consuming routes, driving up the cost of food, fuel, and fertilizer.Nearly 34 million people, almost two-thirds of the population, need humanitarian support, making Sudan "the world's largest humanitarian crisis". The situation is dire, with hundreds of thousands of children acutely malnourished, and millions being deprived of an education. Women and girls are facing systemic and brutal sexual violence.

Aid organizations are intensifying their efforts to deliver humanitarian relief into Iran, where the ongoing conflict between the United States and Israel has resulted in a severe humanitarian crisis. The International Federation of Red Cross and Red Crescent Societies (IFRC) has successfully delivered 'life-saving' aid and medical supplies into the country, marking one of the first humanitarian shipments since the conflict began.The aid convoy, which entered Iran through Turkey on Sunday, included 200 trauma kits containing emergency medical supplies, along with tents and blankets. This shipment is critical as humanitarian supply chains into Iran have been severely disrupted, making it increasingly difficult and costly for essential medical and relief items to reach those in need.The conflict has had a devastating impact on the population, with over 3,000 people killed and up to 3.2 million displaced, according to Iranian authorities. The Turkish Red Crescent Society has also dispatched four trucks carrying 48 tonnes of aid, including emergency shelters, hygiene kits, and first-aid supplies.The International Committee of the Red Cross (ICRC) has also contributed to the relief efforts, dispatching 14 trucks from Jordan carrying household supplies for around 25,000 people. Additionally, the ICRC has donated 200 generators and 100 motor pumps to the Iranian Red Crescent Society to support relief and rescue operations.The relief efforts are crucial as air and sea routes have been blocked by the conflict, making overland crossings through Turkey and Jordan critical for aid delivery. The humanitarian crisis in Iran continues to worsen, with 3.6 percent of the population displaced and 62,000 homes destroyed, according to the Turkish Red Crescent Society's president, Fatma Meric Yilmaz.
