A major US study has found that many paediatricians prescribe ADHD medication to children as young as four and five immediately after diagnosis, despite guidelines recommending six months of behavioural therapy first. The analysis, published in JAMA Network Open and based on more than 9,700 children, revealed that 42% of young patients received medication within a month of diagnosis, while only 14% began treatment after the recommended six-month delay. Experts warn this rush to medicate overlooks the benefits of behavioural therapy, which can help children develop coping skills and improve family dynamics. Although ADHD drugs like Ritalin and Concerta are…

Groundbreaking research suggests the shingles vaccine may provide significant cardiovascular protection, reducing the risk of heart attacks and strokes by nearly 20%. In the first global systematic review and meta-analysis on the subject, researchers found that adults who received the herpes zoster vaccine had an 18% lower risk of stroke or heart attack. Among those aged 50 and older, the reduction was 16%. The study, which analyzed 19 international studies, will be presented at the European Society of Cardiology’s annual meeting in Madrid. Experts suggest that by preventing shingles, which can trigger harmful inflammation, the vaccine may indirectly protect against…
A new study suggests that ocean acidification may erode shark teeth, potentially undermining their ability to feed and threatening marine ecosystem stability. Sharks naturally lose and replace teeth in rows, but more acidic oceans could accelerate tooth damage faster than replacement rates allow. Researchers tested 60 naturally shed teeth from blacktip reef sharks in tanks simulating current ocean pH (8.1) and projected future levels (7.3). After eight weeks, the teeth in acidic water suffered double the damage, including root corrosion and altered serrations. Lead author Maximilian Baum, from Heinrich Heine University, warned that this could hinder sharks’ hunting efficiency, especially…
Wild bumblebees carefully choose different flowers to meet their nutritional needs, according to a new study. Over eight years, researchers in the Colorado Rockies observed eight species of wild bumblebees and mapped their pollen-based diets. By analyzing pollen samples in the lab, the team measured protein, fat, and carbohydrate levels, discovering that bees adjust their diets to match seasonal changes in nutrient availability. Protein levels in flowers varied widely, ranging from just 17% to as much as 86%. Spring flowers tended to offer protein-rich pollen, while late-summer blooms provided more fats and carbohydrates. Larger-bodied bees with long tongues preferred protein-heavy…
Surgeons in China have successfully transplanted a genetically modified pig lung into a brain-dead human recipient, marking the first reported case of its kind. The transplanted lung functioned for nine days without triggering hyperacute rejection or infection, though it did eventually show fluid buildup and progressive antibody-driven damage. The procedure, described in Nature Medicine, involved a lung from a Chinese Bama Xiang pig with six genetic modifications to reduce immune rejection. Challenges and Future Prospects Experts caution that while this represents an important step in xenotransplantation research, pig lungs face unique hurdles compared with other organs like kidneys and hearts.…
A new long-term study suggests that following a Mediterranean-style diet can help lower the risk of dementia, even among people with genetic predispositions. Dementia is influenced by genetic, lifestyle, and environmental factors, with the APOE4 gene variant being one of the strongest known genetic risks for Alzheimer’s disease. Having one copy of APOE4 triples the risk, while two copies increase it up to twelvefold. Study Shows Strongest Benefits for High-Risk Groups Researchers from Harvard-affiliated hospitals tracked over 5,700 participants for more than three decades, analyzing diet, genetics, and cognitive health. They found that individuals who ate diets rich in vegetables,…
Once largely untouched, Antarctica is now seeing record numbers of visitors. Annual arrivals have jumped from fewer than 8,000 in the 1990s to more than 124,000 in the 2023–24 season, with projections suggesting up to 450,000 visitors by 2034. Researchers warn that this rapid rise is leaving a deep human footprint on the world’s last great wilderness. A new study in Nature Sustainability shows concentrations of toxic metals near human activity zones are now 10 times higher than 40 years ago, linked to emissions from ships, aircraft and vehicles. Pollution, Wildlife Disturbance and Melting Snow Tourism contributes far more than…
Scientists studying climate impacts found that extreme heat affects our emotions. Analysis of more than a billion social media posts revealed striking patterns. When temperatures climbed above 35°C, posts turned more negative, especially in lower-income countries. The research combined sentiment scores with local weather conditions to measure emotional responses. MIT and global experts examined posts from X and Weibo. In wealthier nations, negativity rose 8%, but in poorer ones, it jumped 25%. This gap highlights how vulnerable communities face stronger emotional impacts from heat. Hot Weather and Human Behaviour Links between heat and aggressive behaviour go back decades. Drivers lose…
Asia leads cryptocurrency growth, and the United States has recently accelerated its push under Trump’s second presidency. Europe has instead focused on detailed oversight of the sector. Bitcoin, the first cryptocurrency launched in 2009, has soared in value from just cents to nearly $120,000. Once a niche alternative to state currencies, crypto has entered the mainstream, gaining the attention of investors, banks, and lawmakers. The EU’s MiCA directive sets the rules: customer funds must be held separately, companies face audits, registration fees, and strict identity checks. Supporters claim these standards provide clarity and customer protection. Opponents caution that such measures…
Duolingo apologised after a German exercise described Harry Potter author J.K. Rowling as mean. The company quickly deleted the content. The lesson asked whether students liked Harry Potter books. The suggested answer included criticism of the writer’s personality. In a statement, the platform said it regretted the offence caused and confirmed the lesson would disappear from the app. The controversy reflected ongoing debates over Rowling’s highly divisive remarks on trans rights, which many public figures and fans condemned. Actor Daniel Radcliffe expressed sadness over Rowling’s comments and explained he continues to support full equality for LGBTQ people. Public Reactions and…
