A new large-scale study in the United States has found that young children diagnosed with attention-deficit/hyperactivity disorder (ADHD) are often prescribed medication far sooner than recommended by medical guidelines. Experts advise that children around four or five years old should first receive six months of behavioural therapy before starting on drugs such as Ritalin or Concerta. The study, published in JAMA Network Open, analyzed data from more than 9,700 children and found that 42.2% were prescribed ADHD medication within one month of their diagnosis, while only 14.1% waited more than six months. Lead author Dr Yair Bannett of Stanford University…
A global systematic review has found that the shingles vaccine is associated with an 18% lower risk of heart attack or stroke in adults. The analysis, which combined results from randomized trials and observational studies, suggests that vaccination against shingles may offer protective cardiovascular effects beyond preventing the viral infection itself. Researchers believe the benefits could be linked to reducing inflammation caused by shingles, which can contribute to heart and circulatory problems. While the vaccine is typically recommended for older or immunocompromised adults, these findings indicate potential advantages even for younger populations. Experts caution that more research is needed to…
Sharks could face difficulties feeding efficiently in the future as ocean acidification threatens to weaken their teeth, potentially affecting both their populations and marine ecosystem stability. Shark jaws are equipped with multiple rows of teeth that are continuously replaced, but acidifying oceans could accelerate damage beyond their natural replacement rates, the study warns. Ocean acidification occurs when the oceans absorb carbon dioxide from the atmosphere, lowering pH levels. By 2300, projections suggest ocean pH could drop from 8.1 to 7.3, with “profound implications for marine organisms,” according to the research. To examine the effects, scientists placed 60 naturally shed blacktip…
A new 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, analyzing the pollen they collected and discovering wide variation in nutrient content. Protein levels ranged from 17% to 86%, with spring flowers generally richer in protein and late-summer flowers higher in fats and carbohydrates. Bees adjusted their diets as their colonies developed, and species occupied distinct nutritional niches. Larger bees with longer tongues preferred high-protein, low-sugar pollen, while smaller bees favored pollen richer in carbohydrates and fats. The…
Surgeons in China have successfully transplanted a genetically modified pig lung into a brain-dead human recipient, with the organ functioning for nine days. The procedure, published in Nature Medicine, represents a significant advance in xenotransplantation, a field aimed at addressing the global organ shortage. According to the World Health Organization, only about 10% of worldwide transplant demand is currently met. The lung came from a Chinese Bama Xiang pig with six genetic modifications designed to reduce rejection by the human immune system. The recipient, a 39-year-old male, retained his own remaining lung, which helped compensate for any damage to the…
A new study suggests that following a Mediterranean-style diet can help reduce the risk of dementia, even for people with high genetic susceptibility. The diet, rich in vegetables, fruits, nuts, whole grains, and low in red and processed meats, was associated with slower cognitive decline over a 30-year period. Researchers found that the benefits were particularly strong for individuals carrying two copies of the APOE4 gene, a major risk factor for Alzheimer’s disease. Study Highlights and Implications The study, published in Nature Medicine, analyzed data from more than 4,200 women and nearly 1,500 men, tracking dietary habits, genetic profiles, blood…
Antarctica, long considered Earth’s last great wilderness, is increasingly affected by human activity. Visitor numbers have surged 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, 118,491 tourists travelled to the region, over 80,000 of whom set foot on the continent. Most arrive on smaller expedition vessels, while others observe from ship decks. Despite guidelines enforced by the International Association of Antarctica Tour Operators (IAATO), including limits on shore landings and biosecurity checks, tourism itself contributes to significant CO₂ emissions, with an average…
A global study shows that hot weather directly influences mood. Scientists reviewed more than one billion social media posts from 157 countries. Findings revealed negativity increased sharply once temperatures exceeded 35°C. The effect was strongest in poorer regions compared to wealthier nations. Researchers from MIT and their partners rated emotional tone in posts on X and Weibo. They matched this data with daily weather conditions. Results showed negativity rose 25% in low‑income areas, while in high‑income countries it rose only 8%. Behavioural Effects of Heat Hot weather has long been tied to anger and aggression. Past research showed drivers honk…
Asia speeds ahead with cryptocurrency growth, while the US has gained momentum under Trump’s second presidency. Europe, instead of focusing on rapid development, has turned its attention to regulation. Bitcoin’s surge from a few cents in 2009 to nearly $120,000 today reflects just how mainstream crypto has become. The EU’s MiCA directive sets out strict rules: separate storage of customer funds, mandatory audits, hefty registration fees, and verified transfers. Regulators call this protection for users and stability for markets. Critics counter that high costs and complex procedures discourage young companies and could weaken Europe’s position in the global race. Polish…
Duolingo apologised after a German lesson instructed learners to call J.K. Rowling mean. The company has since erased the phrase. The exercise asked whether learners like Harry Potter books. The given solution criticised the author rather than focusing only on language. Duolingo admitted the example was inappropriate, offered regret, and promised to avoid such material in future lessons. Rowling remains a source of controversy for her comments on trans rights, which have been condemned by celebrities and campaigners. Actor Daniel Radcliffe said he was saddened by her views and emphasised unwavering support for LGBTQ people. Cultural Fallout and Literary Disputes…
