A simple cheek-swab test may allow doctors to identify children at risk of a potentially fatal heart condition up to five years before conventional diagnosis, new research suggests. The condition, arrhythmogenic cardiomyopathy (ACM), is often genetic and is responsible for over 10% of sudden cardiac deaths in children. ACM occurs when abnormalities in the proteins between heart cells disrupt the heart’s structure and electrical activity, sometimes striking without warning. Researchers found that these protein changes can also be detected in the lining of the cheeks, leading to the development of a two-minute swab test. The findings were presented at the…

Oscar Piastri delivered a commanding pole-to-flag victory at the Dutch Grand Prix, widening his lead in the Formula 1 drivers’ championship, while teammate Lando Norris suffered heartbreak with a late retirement. From the first corner, the 24-year-old Australian led confidently, weathering light rain and three safety-car restarts to secure a flawless win. The result gives Piastri a 34-point advantage over Norris, a significant swing in the tightly contested title race with just nine rounds remaining. For Norris, the day ended in cruel fashion. Running second, the British driver’s cockpit filled with smoke due to an oil leak with only seven…

A new study in the United States has found that children aged four and five diagnosed with attention-deficit/hyperactivity disorder (ADHD) are often prescribed medication far sooner than guidelines recommend. Official guidance advises that young children should first undergo six months of behavioural therapy before starting drugs such as Ritalin or Concerta. The analysis, published in JAMA Network Open, included more than 9,700 children and revealed that 42.2% were prescribed medication within one month of diagnosis, while only 14.1% received it after six months or more. Dr Yair Bannett, the lead author and assistant professor of paediatrics at Stanford University, described…

A global systematic review has found that receiving the shingles vaccine is linked to an 18% lower risk of stroke or heart attack in adults. The research analyzed 19 studies, including observational studies and randomized trials, highlighting potential cardiovascular benefits beyond protection from shingles itself. Experts suggest the effect may be due to reduced inflammation caused by the virus, which can contribute to cardiovascular problems. While the findings are promising, further research is needed to confirm causation and understand the benefits across different age groups. The study adds to growing evidence that vaccines may help prevent not only infections but…

Sharks could struggle to feed effectively in the future due to ocean acidification, potentially impacting marine ecosystem stability, a new study warns. Shark jaws carry multiple rows of teeth that are continuously replaced, but rapidly acidifying oceans may damage teeth faster than they can be replaced. Sharks with impaired teeth could face difficulties hunting, threatening both their populations and the broader marine food web. Ocean acidification occurs as oceans absorb carbon dioxide, lowering pH levels. By 2300, projections suggest ocean pH could drop from 8.1 to 7.3, a change with “profound implications for marine organisms.” Researchers tested 60 naturally shed…

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,…
