New research indicates that individuals carrying the red‑hair allele have been evolutionary winners in Europe for more than 10,000 years. The study, led by Harvard scientists, examined DNA from nearly 16,000 ancient remains and over 6,000 living Europeans, providing robust proof that human biology continues to evolve long after farming began. Researchers identified 479 genetic variants that show clear signs of positive selection. Among these are genes linked to red hair and fair skin, as well as variants that affect susceptibility to coeliac disease, diabetes risk, baldness and rheumatoid arthritis. The authors suggest that the advantage of red hair may stem from its association with lighter skin, which enhances vitamin D synthesis in low‑sunlight environments—a crucial benefit for early European farmers. Prior to this work, only about 21 traits had been documented as having risen through natural selection, such as lactase persistence. The scarcity of earlier examples had led some to argue that directional selection was rare after modern humans left Africa. By leveraging an unprecedented volume of ancient genomic data and advanced computational methods, the team demonstrated that selection pressures intensified during the transition from hunter‑gatherer societies to agricultural ones, reshaping hundreds of genes across West Eurasia. "With these new techniques and the sheer scale of ancient DNA, we can now observe how selection sculpted our biology in near real‑time," said Dr. Ali Akbari, the study’s first author. Beyond vitamin D, the rise of certain disease‑related alleles poses intriguing puzzles. A mutation that heightens the risk of coeliac disease emerged around 4,000 years ago and has steadily increased, implying that carriers may have enjoyed other survival advantages despite the autoimmune threat. Similarly, the immune‑regulating gene TYK2, which markedly raises tuberculosis susceptibility, grew in frequency between 9,000 and 3,000 years ago before declining, hinting at a complex balance between pathogen defense and disease risk. The analysis also uncovered negative selection against genetic profiles that promote a high body‑fat percentage, supporting the classic “thrifty genes” hypothesis: traits advantageous for storing energy during scarce hunter‑gatherer periods became detrimental once agriculture ensured a steadier food supply. "This work lets us assign both place and time to the forces that have shaped us," noted Prof. David Reich, senior author and Harvard Medical School geneticist. While the findings are confined to West Eurasian populations, they raise broader questions about whether similar evolutionary dynamics occurred elsewhere. The full study appears in Nature.

For the first time, a detailed map identifies the UK’s most severe ammonia pollution hotspots in regions where intensive pig and poultry farms are most concentrated.The analysis, produced by Compassion in World Farming (CiWF) and the environmental group Sustain, shows the highest emission densities in Lincolnshire, Herefordshire and Norfolk. These counties host a large number of confined‑livestock units that drive dangerous levels of ammonia, a nitrogen‑based gas primarily released from animal manure.In the United Kingdom, agriculture accounts for 89% of national ammonia emissions. When released into the atmosphere, ammonia reacts with other pollutants to form fine particulate matter (PM2.5), a leading cause of premature death. The Committee on the Medical Effects of Air Pollutants (COMEAP) estimated that PM2.5 exposure caused between 28,861 and 29,000 early deaths in 2010.The timing of the report is notable: the government is currently reviewing planning regulations that would make it easier to approve new intensive livestock facilities, despite growing concerns over air quality, water contamination and local opposition.Health professionals warn that ammonia‑derived PM2.5 fuels heart disease, stroke, asthma and chronic lung conditions. Dr Amir Khan, a GP and CiWF patron, said, “As a GP, I see first‑hand the toll that air pollution takes on people’s health – and ammonia from intensive farming is a major, yet often overlooked, part of that problem.”Beyond human health, excess nitrogen from ammonia deposition acidifies soils and pollutes rivers. Recent activism in Shropshire halted a proposed poultry megafarm of 230,000 chickens after campaigners argued the council failed to assess the full environmental impact.Rising numbers of industrial poultry units—known as IPUs—along the River Wye and River Severn valleys are identified as a key driver of river pollution. Chicken manure is especially rich in phosphates, which deplete oxygen in waterways and threaten aquatic life.Calculations for the map were based on permitted stocking numbers and average ammonia production factors for different livestock categories, including broiler chickens, indoor egg layers and pigs.Local residents are already feeling the impact. Michele Franks, who lives near a Lincolnshire poultry megafarm, described how shed clean‑outs force her to stay indoors, causing “chest tightness, eye irritation and breathing difficulties” that can last for days.CiWF and Sustain are calling for an end to the expansion of factory farming. Anthony Field, head of Compassion in World Farming UK, warned, “Factory farming sits at the heart of the UK’s ammonia crisis. By cramming large numbers of animals into confined spaces and relying heavily on fertilisers, these intensive systems release far more ammonia than the environment or our bodies can cope with.”

Sudan, one of the world's most impoverished countries, has been ravaged by a civil war that began in 2023. The conflict, driven by a power struggle between the army and the paramilitary Rapid Support Forces (RSF), has left the nation unrecognizable. Over 40,000 people have been killed, and about 14 million – a quarter of the population – have been forced to flee their homes. Civilian infrastructure across the country has been extensively damaged.“We are not just facing a crisis – we are witnessing the systematic erosion of a country’s future,” Luca Renda, the United Nations Development Programme’s (UNDP’s) resident representative in Sudan, told Al Jazeera. A report by the UNDP and the Institute for Security Studies highlights the scale of Sudan’s economic collapse. Even under the most optimistic scenario of peace being achieved in 2026, Sudan would still lose an estimated $18.8 billion in gross domestic product (GDP) by 2043.The war has had a devastating impact on Sudan's infrastructure and basic services. $6.4 billion was lost in GDP in 2023 alone, reflecting a simultaneous collapse across all major parts of Sudan’s economy. The destruction of infrastructure has triggered displacement and made it difficult for people to secure adequate housing or access basic services. Up to 40 percent of power generation capacity has been lost, and key water infrastructure has been destroyed or seized, cutting communities off from clean water and sanitation.The labor market has also been severely affected, with agriculture – once the backbone of Sudan’s economy – severely hit. Cultivated land has shrunk, adversely impacting rural livelihoods. Average incomes have fallen back to levels last seen in 1992. About 90 percent of manufacturing activity has been destroyed in key economic hubs, eliminating thousands of jobs.The oil industry has suffered significantly, with oil output falling amid widespread instability and infrastructure damage. The Khartoum refinery, which previously processed up to 100,000 barrels per day, has been out of operation since July 2023. Key infrastructure, including pipeline routes carrying crude to Port Sudan, has been hit.The collapse of the Sudanese pound and supply chains has caused a sharp rise in living costs. Food prices have surged, with four pieces of bread now costing about 1,000 pounds, an amount that had previously bought six pieces. Wages have failed to catch up with inflation, leaving many households without access to necessities. Nearly half the population is now experiencing acute food shortages.The economic collapse has had a profound impact on Sudan's people, with 34 million people in need of assistance and 19 million facing acute food shortages. The war has caused death, trauma, and profound loss, casting a long shadow over Sudan’s future and dimming the prospects of a generation whose lives are being shaped by violence. If the conflict continues to 2030, Sudan’s economy in 2043 would be about $34.5 billion smaller than it would have been without the war, and GDP per capita would drop by roughly $1,700.

The prospect of a renewed U.S. oil blockade has sparked concerns across Havana’s tobacco fields, where the cigar industry remains a cultural and economic cornerstone. Analysts warn that restricting oil supplies could disrupt the energy‑intensive processes essential for curing, rolling, and transporting premium cigars, potentially undermining production volumes and export revenues. Cuba’s cigar sector accounts for a significant share of the island’s foreign‑exchange earnings, with premium brands commanding premium prices in markets worldwide. A sustained energy shortage would not only raise operational costs but could also force producers to scale back output or seek alternative, less efficient energy sources, eroding the competitive edge that Cuban cigars have long enjoyed. Beyond the immediate economic impact, the blockade could deepen existing tensions in U.S.-Cuba relations. The move may be interpreted as a strategic lever to pressure the Cuban government, yet it also risks alienating stakeholders in the global tobacco trade and could invite retaliatory measures. While the full extent of the blockade’s effect remains uncertain, experts stress that any disruption to the cigar supply chain would reverberate through related sectors—tourism, agriculture, and logistics—exacerbating the island’s broader fiscal challenges. Policymakers on both sides are therefore urged to weigh the economic costs against geopolitical objectives before implementing such a measure.

The Food and Agriculture Organization (FAO) has issued a stark warning: if the Strait of Hormuz remains blocked by the ongoing US‑Israel conflict with Iran, the world could face a food ‘catastrophe’. The disruption is already halting shipments of vital agricultural inputs, a situation that could quickly cascade into higher food prices. FAO chief economist Maximo Torero told Al Jazeera that, for now, food prices have stayed stable because existing stockpiles are absorbing the shock. However, he cautioned that this buffer is temporary and that “the clock is ticking.” FAO agrifood economics director David Laborde added that if traffic does not resume, the resulting strain on energy and fertilizer markets will translate into “higher commodity and retail prices later this year and into 2027.” According to the FAO, 20‑45% of key agrifood inputs—including fertilizers, pesticides and feed—depend on maritime passage through the Hormuz chokepoint. Nearly half of the world’s traded urea, the most widely used fertilizer, also moves through the strait, making global agriculture highly vulnerable. Recent gas supply disruptions have already forced fertilizer plants in the Gulf and beyond to cut or halt production, raising concerns that farmers may have to reduce fertilizer use or face higher production costs. Torero emphasized that poorer countries are especially at risk because planting calendars leave little room for delays; a slowdown in input delivery could quickly lead to “lower output, higher inflation and slower global growth.” The blockade stems from Iran’s decision to bring traffic to a near‑total halt in retaliation for attacks by the United States and Israel, which launched a war on Tehran on 28 February, resulting in the death of Supreme Leader Ayatollah Ali Khamenei. The conflict has already doubled oil and gas prices compared with pre‑war levels. Negotiations between Iranian and US representatives over a 21‑hour marathon failed to secure a permanent ceasefire. Subsequently, US President Donald Trump announced a naval blockade, stating that the navy would interdict ships in international waters that had paid Iran a toll to traverse the strait. The US military later declared it would block all maritime traffic entering and exiting Iranian ports, including those in the Gulf and the Gulf of Oman. FAO officials stress that decisive action—both a sustained ceasefire and the reopening of the waterway—is essential to prevent the looming food crisis from becoming a full‑blown catastrophe.

Benin is set to choose a new head of state on Sunday, April 12, 2026, in an election that appears to favor the governing coalition’s nominee, finance minister Romuald Wadagni. The 49‑year‑old, a former Deloitte executive, has been hand‑picked by outgoing President Patrice Talon, who is constitutionally barred from seeking a third term after a decade in power. With roughly eight million eligible voters on the rolls, the contest requires a candidate to secure more than 50 % of the vote; otherwise a runoff would be scheduled for May 10. In practice, only two names appear on the ballot: Wadagni, representing the Progressive Union Renewal‑Republican Bloc alliance, and Paul Hounkpe, the 56‑year‑old former teacher and culture minister who runs under the Cowry Forces for an Emerging Benin (FCBE) banner. Wadagni’s campaign emphasizes continuity of Talon’s economic reforms. Under Talon, Benin’s budget tripled and the country posted its strongest GDP growth in over twenty years, with the International Monetary Fund estimating a 7 % expansion in 2025. Investment in trade, agriculture and the Cotonou port has driven this performance, though benefits remain uneven, especially in the poorer northern regions. Security concerns dominate the northern frontier, where al‑Qaeda and IS‑linked militias from the Sahel have intensified cross‑border raids. Recent attacks by the JNIM network killed 54 soldiers in 2025 and another 15 in early 2026. A failed coup attempt in December 2025, allegedly motivated by neglect of troops in the north, left about 100 suspects awaiting trial. Wadagni has pledged to create municipal police forces to protect border towns, while Hounkpe warns that the current administration has sidelined citizens despite macro‑economic gains. Beyond economics and security, the election raises questions about Benin’s democratic health. Talon’s government has been criticized for suppressing protests, extending presidential terms from five to seven years, and enabling the president to appoint Senate members—moves that have effectively eliminated opposition representation. In the January parliamentary vote, Talon’s allies captured all 109 seats, and the main opposition party, the Democrats, failed to field a presidential candidate. Observers note that voter turnout will be a key barometer of public sentiment. The last presidential election saw only about 50 % participation. Al Jazeera reporter Ahmed Idris described the atmosphere at a governing‑party rally in Cotonou as “lively,” but cautioned that it may not reflect the broader mood in a nation where democratic space appears to be shrinking. Should Wadagni win, he pledges to build on a decade of “economic transformation,” expanding development hubs and healthcare access while maintaining fiscal discipline. Hounkpe, positioned as a moderate alternative, promises to lower basic commodity prices and secure the release of political prisoners detained under Talon’s rule. The outcome will shape Benin’s trajectory at a critical juncture: balancing sustained economic growth, confronting escalating security threats from the Sahel, and navigating the tension between authoritarian tendencies and the country’s reputation as one of West Africa’s more stable democracies.

It's been a year since the Trump administration's sweeping cuts to the federal workforce, and the effects are still being felt. Tens of thousands of employees were offered buyouts or faced termination, leaving many to navigate a difficult job market. Maggie, a former employee of the US Office of Personnel Management, took a buyout offer in May 2025. She has since applied to over 250 jobs but is still waiting for an ethics letter to start work elsewhere. 'I couldn't be without health insurance through the delivery of my baby,' she said, highlighting the challenges faced by those who lost their jobs. The federal workforce has declined by about 355,000 employees since Trump took office, with 18,000 workers leaving in March 2026 alone. The cuts have left remaining government workers overwhelmed, trying to keep essential public services afloat. Charles Melton, a 20-year veteran of the US Department of Agriculture, took early retirement but still helps former colleagues with job applications. 'I'm still mad as hell,' he said. 'We just got thrown away like garbage.' The impact on public services has been significant, with customer service at the Social Security Administration worsening and healthcare workers at the Department of Veterans Affairs reporting ongoing staffing issues. The shutdown of USAID has resulted in hundreds of thousands of deaths worldwide due to the spread of infectious diseases and malnutrition. The White House has declined to comment, but Scott Kupor, OPM's director, stated that 'reshaping the federal workforce is essential to building a government that works for the American people, not the bureaucracy.'

The International Monetary Fund has cautioned that the US‑Israel war on Iran could ignite a new wave of global inflation, jeopardising the outlook for world growth even if the current cease‑fire endures. IMF Managing Director Kristalina Georgieva announced on Thursday that the Fund will lower its growth projection for the global economy at next week’s IMF‑World Bank Spring Meetings, stating that the conflict has turned a potential upgrade into a growth downgrade. Earlier this year the IMF had lifted its forecast to 3.3 % growth for the 191‑member economies. That optimism evaporated after the war erupted on 28 February, driving up oil and natural‑gas prices, damaging energy infrastructure such as refineries and tanker terminals, and disrupting fertilizer shipments essential for global agriculture. Georgieva warned that the conflict is eroding business and consumer confidence and urged member nations to “get your house in order” as heightened defence spending adds further strain to the world economy. She also expressed confidence that the IMF will secure U.S. congressional approval this year for a 50 % increase in quota‑based lending resources, unlocking more of its roughly $1 trillion lending capacity. The United States, the Fund’s largest shareholder, would thereby provide crucial financial reassurance amid uncertain future developments. In a newly released report, the IMF estimated that countries directly involved in armed conflict typically see output fall by about 3 % at the outset, accumulating to roughly 7 % losses over five years. However, the study noted that economies like the United States may avoid severe economic damage because the fighting does not physically affect their own territory. Central banks are also on alert. Georgieva emphasized that “the central bank cannot afford to let inflation spiral out of control,” a statement that precedes the U.S. Federal Reserve’s two‑day policy meeting scheduled for 28–29 April, where interest‑rate decisions will be made amid political pressure from President Trump to lower rates. Other monetary authorities, including the Bank of Mexico, warned that the Middle‑East turmoil could push inflation higher in Latin America’s second‑largest economy, underscoring the broader spill‑over risks of the conflict.

The UK government’s latest proposal to ease planning restrictions for large‑scale chicken operations has drawn sharp criticism for being short‑sighted and potentially jeopardising the nation’s food resilience.Advocates of the change argue that lower stocking densities constitute a modest welfare improvement, yet critics contend this is a minor concession that does little to address the systemic cruelty of intensive poultry systems. Moreover, the fast‑growing, low‑welfare breeds used in these units depend almost entirely on imported soy for feed, creating a strategic vulnerability to trade disruptions – a risk highlighted by the ongoing conflict in Iran.Beyond ethical concerns, the model is increasingly economically unsustainable. Frequent disease outbreaks, soaring energy prices and extreme weather events such as heatwaves and flooding are already eroding profitability and further degrading animal welfare. These pressures underscore the fragility of a sector that remains heavily reliant on a single, high‑intensity production model.Local communities have also voiced strong opposition, with recent planning objections succeeding and legal actions launched against producers and retailers for alleged environmental damage. This grassroots resistance signals a growing public demand for a more nature‑friendly agricultural framework.Stakeholders, including World Animal Protection’s UK country director Ruth Tanner, call for an immediate halt to the proposed deregulation. They propose capping the number of industrial units and investing in alternatives such as agroforestry and regenerative farming, which promise a more resilient, high‑welfare, and equitable future for British agriculture.
