A study in the Colorado Rockies shows that wild bees strategically select flowers to meet their nutritional needs, balancing protein, fats, and carbohydrates. Over eight years, researchers tracked eight bumblebee species and analyzed the pollen they collected, revealing large variations in nutrient content. Spring flowers were richer in protein, while late-summer blooms offered more fats and carbohydrates. Individual bees adjusted their diets as colonies grew, and different species occupied distinct nutritional niches. Larger bees with longer tongues preferred protein-rich pollen, while smaller bees favored pollen higher in carbohydrates and fats. These findings highlight that bees forage strategically rather than randomly,…

For the first time, surgeons have transplanted a genetically modified pig lung into a brain-dead human, where it remained functional for nine days. The procedure, described in Nature Medicine, represents a step forward in xenotransplantation, a field aimed at addressing the global shortage of donor organs. According to the World Health Organization, only around 10% of the worldwide demand for transplants is currently met. The left lung came from a Chinese Bama Xiang pig genetically modified with six alterations to reduce rejection by the human immune system. The recipient, a 39-year-old male, showed no signs of hyperacute rejection or infection…

New research suggests that following a Mediterranean-style diet can reduce the risk of developing dementia and slow cognitive decline, even for people with strong genetic predispositions. The diet, rich in vegetables, fruits, nuts, and whole grains while low in red and processed meats, was linked to better brain health over a 30-year period. APOE4 Gene and Personalized Strategies One of the most significant genetic risk factors for Alzheimer’s disease is the APOE4 variant. Carrying one copy triples the risk, while two copies increase it up to 12 times. The study, published in Nature Medicine, found that the protective effects of…

Antarctica, the planet’s last great wilderness, is under increasing pressure from human activity. Visitor numbers have skyrocketed from fewer than 8,000 annually in the 1990s to over 124,000 in 2023–24, with projections suggesting up to 450,000 by 2034. During the 2024–25 season, more than 118,000 tourists traveled to the region, with over 80,000 setting foot on the continent. While the International Association of Antarctica Tour Operators (IAATO) enforces guidelines, including biosecurity checks and limits on shore landings, each tourist trip still generates an average of 5.44 tonnes of CO₂, adding to the environmental strain.

A massive study of more than a billion social media posts across 157 countries has revealed that extreme temperatures consistently lower people’s moods. Once daily highs move past 35°C, emotional tone becomes noticeably more negative. The strongest effects were recorded in low‑income regions, where residents showed three times the shift seen in wealthier countries. MIT researchers and their partners matched daily sentiment scores from online platforms with local climate data to arrive at these findings. Heat’s Influence on Behaviour Links between hot conditions and human behaviour go back decades. Observations show that drivers in heat honk their horns more quickly,…

Across the globe, cryptocurrency activity is bursting: Asia remains the leader, and the United States has ramped up its game in recent years. Europe, rather than chasing growth, is prioritizing strict oversight. Since its inception in 2009, Bitcoin has grown from a digital curiosity worth mere cents into a global asset worth nearly $120,000, forcing governments and regulators to pay attention. To respond, the EU established MiCA, a framework obliging companies to hold client assets separately, undergo regular audits, pay licensing fees, and verify transactions. Brussels promotes this as essential for safety and market order. Yet the industry warns that…

Duolingo apologised after criticism of a German exercise that called J.K. Rowling mean. The company deleted the sentence immediately. The task asked if learners liked Harry Potter books. The model answer went further by insulting the author herself. Duolingo admitted the example was inappropriate, expressed regret, and promised to ensure lessons remain neutral and focused on language. Rowling continues to polarise public opinion with her views on trans rights, which have been condemned by many actors and activists. Daniel Radcliffe said he was saddened by her stance and pledged to keep supporting LGBTQ people and their rights. Broader Debate and…

Google has introduced new upgrades to its Gemini AI platform alongside the launch of the Pixel 10 lineup, Pixel Watch 4, and updated earbuds. The company is positioning these tools as more proactive assistants, capable of anticipating needs rather than waiting for prompts. A central feature of the rollout is Magic Cue, exclusive to the Pixel 10 series. It blends information from services such as Gmail, Maps, and Calendar to anticipate what might be useful in the moment. For example, flight details will pop up automatically when calling an airline, or a brunch message can trigger café suggestions and calendar…

Sperm counts have dropped almost 60% since the 1970s. The decline accelerated to over 2% annually since 2000. Chemicals in plastics, such as phthalates and bisphenols, disrupt hormones. These chemicals harm fetal development in boys and lower fertility in adulthood. Political Resistance Hinders Chemical Controls The fertility crisis grows with increased plastic production. Efforts to regulate harmful chemicals face strong political opposition. Global treaty talks failed after oil and gas producers blocked limits on toxic additives. Experts urge stronger chemical laws, innovation in safe materials, and global cooperation. Individuals can reduce exposure with glass or stainless steel, but large-scale action…

Researchers led by Prof. David Salt have made a key discovery in how microbes affect the fermentation of cocoa beans. By analyzing beans from three Colombian regions, they found that the presence of certain microbes leads to unique flavor profiles in chocolate. Distinct Microbes Create Unique Tastes Beans from Santander and Huila developed fruity and floral flavors during fermentation, while beans from Antioquia did not, due to different microbes at work. The team identified nine specific microbes that combine to produce citrus, fruit, and floral notes. New Potential for Cocoa Farming and Chocolate When sterile beans were fermented with this…
