Surgeons in China have successfully transplanted a genetically modified pig lung into a brain-dead human for the first time, with the organ functioning for nine days. The research, published in Nature Medicine, represents a significant advance in xenotransplantation, a field aimed at addressing the global shortage of donor organs. According to the World Health Organization, only about 10% of the need for transplants worldwide is currently being met. The lung came from a Chinese Bama Xiang pig with six genetic modifications designed to reduce rejection by the human immune system. It was implanted into a 39-year-old brain-dead male recipient, where…

New research suggests that following a Mediterranean-style diet could help lower the risk of dementia and slow cognitive decline, even for people with strong genetic predispositions. Dementia arises from a mix of genetic, lifestyle, and environmental factors, and one of the most significant genetic risks comes from the APOE4 variant. Carrying one copy of APOE4 triples the risk of Alzheimer’s disease, while two copies increase the risk up to twelvefold. The study, published in Nature Medicine, analyzed data from more than 5,600 participants over three decades, tracking long-term diet, blood samples, genetic information, and cognitive performance. People who adhered closely…

Antarctica, the planet’s last great wilderness, is facing increasing pressure from human activity. Visitor numbers have risen dramatically, from fewer than 8,000 annually in the 1990s to more than 124,000 in 2023–24, with projections suggesting up to 450,000 by 2034. During the 2024–25 season, over 118,000 tourists travelled to the region, more than 80,000 of whom set foot on Antarctic soil. Even with guidelines from the International Association of Antarctica Tour Operators (IAATO), including shore landing limits and biosecurity checks, tourism itself contributes significantly to environmental strain, with an average trip generating 5.44 tonnes of CO₂ per passenger. Pollution and…

Scientists have shown that extreme heat changes how people feel globally. Over one billion social media posts from 157 countries were analysed. Results revealed that above 35°C, negative emotions rose sharply. The strongest declines in mood appeared in poorer regions compared to wealthier nations. MIT researchers and partners rated each post for sentiment and connected it with local weather. They found people in low‑income countries were three times more affected by heat stress than those in high‑income areas. Behaviour and High Temperatures Previous studies confirm how heat worsens tempers. Drivers honk more in hot traffic, writers use harsher language, and…

Asia races ahead with digital asset growth, while the US has recently increased its pace under Trump’s second term. Europe, by contrast, focuses more on legislation than on fostering rapid expansion. Since its creation in 2009, Bitcoin has shot up from cents to nearly $120,000, marking crypto’s transformation from experimental currency to mainstream investment. To manage this shift, the EU introduced MiCA, requiring companies to separate client funds, undergo audits, pay registration fees, and verify transfers. Policymakers claim this provides safety and stability. Many industry players argue it raises costs, discourages innovation, and pushes crypto firms closer to traditional finance…

Duolingo apologised after a German lesson told learners to describe J.K. Rowling as mean. The company has since withdrawn the example. The exercise centred on Harry Potter books. The approved answer strayed into commentary on the author instead of language practice. In response, Duolingo admitted the sentence was inappropriate, expressed regret, and promised lessons will stick to neutral material. Rowling’s views on trans rights remain heavily disputed, drawing anger from activists, fans, and well-known figures connected to Harry Potter. Daniel Radcliffe said her comments upset him and stressed his continued commitment to supporting LGBTQ communities. Public Reaction and Ongoing Disputes…

Scientists report that Arctic sea ice has shown little decline since 2005, an unexpected development considering global heating. They explain the slowdown through ocean circulation changes that temporarily reduced melting, despite steadily increasing greenhouse gas emissions worldwide. The pause is only short-term, researchers warn, and melting is expected to accelerate again within the next decade. A Pause Amid Decline September sea ice levels remain about half of those measured in 1979, when Arctic satellite monitoring was first established. Experts emphasize there is no recovery. Ice-free summers later this century are still projected, carrying severe ecological and human costs. As ice…

Since the 1970s, sperm counts have declined by nearly 60%, doubling the rate of loss since 2000. Chemicals in plastics, such as phthalates and bisphenols, disrupt hormones. These chemicals harm fetal development in boys, leading to lower fertility in adulthood. Political Resistance Halts Chemical Regulation Plastic production has surged, worsening the fertility crisis. Efforts to regulate harmful chemicals face political roadblocks. Global treaty talks failed after oil- and gas-producing nations opposed restrictions on toxic additives. Experts call for stronger regulations, safer material innovations, and international collaboration. While individuals can minimize exposure by using glass or stainless steel, only large-scale policy…

An international research team led by Prof. David Salt from the University of Nottingham made a significant breakthrough in understanding cocoa bean fermentation. Studying beans from three Colombian regions, the team found that specific microbes during fermentation play a crucial role in shaping the final chocolate flavor. Beans from Santander and Huila developed rich fruity and floral notes, whereas beans from Antioquia lacked these flavors due to the presence of different microbial communities. Using advanced genetic analysis, the researchers identified nine key microbes that work together to create distinct citrus, fruit, and floral flavor profiles. In a controlled experiment, sterile…
