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.

Chris Walton, a renowned biologist and lecturer at Cranfield University, has passed away at the age of 69 due to brain cancer. He was widely respected for his pragmatic approach to getting things done and was often referred to as an honorary engineer by his colleagues.Walton's research focused on volatile organic compounds (VOCs) in various matrices, including breath, sweat, blood, urine, and faeces. He discovered links between specific VOCs and different human diseases, developing new methods to measure them. His work on environmental sensors, particularly low-cost air-quality monitors, was also notable.Born in Batley, West Yorkshire, Walton was the first in his family to attend university, graduating from Leicester University with a degree in biology in 1978. He later earned an MSc in biological computation at York University and a PhD from Coventry University.Walton's career spanned various institutions, including Imperial College London and EDS, an IT service provider. He joined Cranfield University in 1998 and became a lecturer in analytical technology. He was known for his sympathetic ear for students and his wise advice to younger colleagues.Walton is survived by his partner, Lorraine Morgan, and his daughter, Elizabeth.

South Korea is seeking to capitalize on the Iran crisis to accelerate its transition to renewable energy, with a focus on expanding its 'solar income village' program. The initiative, which aims to reach 2,500 villages by 2030, has already shown promising results in rural areas like Guyang-ri, where a one-megawatt solar installation generates $6,800 in net profit monthly. The village uses this revenue to fund communal benefits, including free meals for residents and a 'happiness bus' for elderly people. This approach has strengthened community bonds and improved quality of life, demonstrating the potential for renewable energy to drive social and economic development. President Lee Jae Myung has emphasized the need for a faster clean energy transition, citing South Korea's heavy reliance on imported energy, including crude oil from the Strait of Hormuz. The government has increased funding for renewable energy projects, allocating a supplementary budget of about 500bn won to energy transition, which includes grid infrastructure upgrades and support for renewable energy projects. However, challenges persist, including the country's reliance on Chinese supply chains for solar panels and the need to address grid capacity limitations. Environmental groups have expressed concerns that the government's response to energy transition falls short, citing the allocation of 5tn won to absorb fossil fuel price hikes, including direct subsidies to oil refineries. Despite these challenges, experts believe that the window for transformative change is open, and the government's institutional courage will be crucial in defining South Korea's energy future.

Rebuilding opens on a bleak, charred horizon, introducing Dusty (Josh O’Connor), a Colorado rancher whose ancestral land has been reduced to ash by a recent wildfire. A bank official’s blunt refusal to extend a loan underscores the decade‑long bleak outlook for the barren property.Stripped of his home, Dusty relocates to a spartan, government‑funded trailer camp and takes a humbling highway‑maintenance job. The film deepens his personal stakes through interactions with his ex‑wife Ruby (Meghann Fahy), their ten‑year‑old daughter Callie‑Rose (Lily LaTorre), and his ailing mother‑in‑law Bess, portrayed by Oscar‑winner Amy Madigan. A poignant scene shows Dusty ferrying Callie‑Rose to the local library, where they share a shaky Wi‑Fi connection for her schoolwork.Amid the trailer community, Dusty forms a tentative bond with the resilient Mali (Kali Reis), hinting at a potential romance beyond mere friendship. Their collective moments around a campfire evoke the tone of Chloé Zhao’s Nomadland, positioning the film within a growing genre of American stories about displacement and survival.Notably, the narrative avoids direct references to climate change or governmental responsibility, presenting the wildfire as an isolated tragedy rather than a symptom of a broader environmental crisis. This omission mirrors a recurring pattern in U.S. cinema, where the focus remains on personal resilience rather than systemic solutions.O’Connor delivers a nuanced performance, channeling the restrained British sensibility of his earlier work into Dusty’s quiet strength and vulnerability. His portrayal anchors the film’s emotional core, while the supporting cast—particularly Madigan’s compassionate Bess and Reis’s tough‑yet‑tender Mali—adds depth to the community portrait.Rebuilding arrives in UK cinemas on 17 April, offering audiences a contemplative look at loss, renewal, and the fragile ties that bind families and strangers alike.

The Marine Stewardship Council (MSC), a leading certifier of sustainable seafood, has been accused of masking widespread labour abuses through its 'blue tick' scheme. A recent study found that one in five vessels where crew reported abuses to the International Transport Workers' Federation (ITF) were certified by the MSC.The study identified 80 cases of labour abuses onboard 72 vessels in 25 MSC-certified fisheries across the globe. These abuses included forced labour, human trafficking, and forced criminalisation, as well as unpaid or delayed wages, excessive hours, violence, harassment, and denial of medical care.The MSC has long claimed that it is an environmental organisation with no social assurance mandate nor labour assessment capacity. However, Chris Williams, ITF fisheries co-ordinator, said that this risks masking abuses and leading people to buy products that aren't necessarily what they think they are.Dr. Jessica Sparks, co-author of the report, added that the MSC's policies and practices may obscure labour abuses in seafood supply chains by undermining enforcement efforts and reducing scrutiny. The study's findings have sparked concerns that the MSC's 'blue tick' scheme may be creating an 'illusion' of ethical sourcing.The International Labour Organization estimated in 2022 that about 128,000 workers were trapped in forced labour on fishing vessels globally. The MSC has engaged in evolving efforts to support the elimination of forced and child labour in supply chains, but critics argue that more needs to be done.

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.”

A large-scale fire broke out at the Viva oil refinery located in Geelong, Australia, early on April 16, 2026. Video footage circulating online shows thick plumes of smoke billowing from the facility, prompting swift action from local fire services and emergency responders. Authorities have mobilised multiple fire‑fighting units to contain the blaze, emphasizing the priority of protecting nearby residential areas and preventing environmental contamination. While details on the fire’s origin remain under investigation, officials have warned that the incident could temporarily affect the refinery’s output, potentially influencing regional fuel supplies. Industry analysts note that any interruption at a major refining hub like Viva can have ripple effects across the domestic energy market, possibly leading to short‑term price fluctuations for gasoline and diesel. The incident also underscores the importance of rigorous safety protocols in high‑risk industrial sites. As the situation develops, the Department of Environment and Energy has pledged to monitor air quality and assess any ecological impact. Residents in the vicinity have been advised to stay informed through official channels and to follow any evacuation or safety instructions issued by emergency services.

Budget airline easyJet has issued a profit warning, citing the impact of the Iran conflict on fuel prices and bookings. The airline has seen fuel costs rise by £25m in the last month alone, driven by the escalating tensions in the Middle East.EasyJet expects to report an increased pre-tax loss of £540-£560m for the six months to March, up from £394m in the first half of 2024-25. The carrier typically generates most of its revenue in the second half of the year, which includes the peak summer period.The airline has hedged 70% of its fuel needs for the rest of the financial year to September, but each $100 movement in the spot price of jet fuel per metric tonne adds £40m in costs for its unhedged supply. Currently, the price is about $800 higher than before the conflict started.Chief executive Kenton Jarvis said demand remained strong in the short term, but customers were leaving it later to book due to economic uncertainty. However, he assured that fuel supplies remained normal and that any talk of having to cancel flights was pure speculation.Jarvis added that there was continued positive demand, but easyJet's financial performance had worsened year on year, impacted by the conflict in the Middle East and the competitive environment in some markets. Shares fell 3% in early trading.
