A recent study led by Prof Becca Levy of the Yale School of Public Health has found that a positive mindset can significantly influence the aging process. The research, which followed over-65s for up to 12 years, discovered that individuals with positive beliefs about aging were more likely to experience improved physical or cognitive function.According to the study, nearly 45% of participants showed an improvement in their physical or cognitive performance over the study period. If extrapolated to the entire US population, this would suggest that more than 26 million older persons are experiencing an improvement in functioning.The findings, which may come as a surprise to some, suggest that having a positive outlook on aging can have a tangible impact on one's health and wellbeing. As the research notes, previous studies have also found that negative aging stereotypes can predict biomarkers for Alzheimer's.While the idea that a positive mindset can influence aging may be unwelcome news for pessimists, it highlights the importance of maintaining a positive outlook on life. As the author notes, it may be time to embrace a more optimistic approach to aging, rather than resigning oneself to a decline in health and wellbeing.

According to a report by IQAir, a Swiss air quality monitoring firm, Pakistan was the world's smoggiest country in 2025 with concentrations of hazardous fine particles known as PM2.5 up to 13 times higher than the World Health Organization's (WHO's) recommended level.The report, which sourced data from 9,446 cities in 143 countries, regions and territories, found that only 13 countries and territories managed to keep their average fine particulate levels below the WHO guideline, an increase from seven in 2024.Pakistan's PM2.5 level was 67.3 microgrammes per cubic metre, significantly exceeding the WHO standard of 5 microgrammes per cubic metre. In comparison, Pakistan's average PM2.5 concentration in 2024 was 73.7 microgrammes.Prolonged exposure to PM2.5 has been linked to higher likelihoods of neurodegenerative conditions, including dementia, Parkinson's disease and Alzheimer's disease.Bangladesh and Tajikistan ranked second and third on IQAir's list of the most polluted countries while Chad, statistically the smoggiest country in 2024, was in fourth place in 2025.The report also noted that Loni, a city in northern India, was identified as the world's most polluted city in 2025 with average PM2.5 levels of 112.5 microgrammes per cubic metre.Globally, only 14 percent of cities met the WHO air quality standard in 2025, down from 17 percent a year earlier. The report highlighted that wildfires, driven by climate change, were a key factor behind worsening global air quality in 2025 as record levels of biomass burning in Europe and Canada released about 1,380 megatonnes of carbon.

CrossSense, an innovative AI software, has been awarded a £1m prize for its groundbreaking technology designed to assist individuals with dementia. This cutting-edge system is integrated into smart glasses and features a user-friendly assistant named Wispy. The smart glasses, equipped with a camera, microphone, and speakers, provide wearers with real-time guidance and support through everyday tasks.Wispy offers verbal cues and text prompts that float in front of the wearer's eyes, enhancing their ability to navigate daily life. The AI assistant can also engage in light conversation, ask questions, and aid reminiscences, significantly improving the wearer's independence and quality of life.The Longitude Prize on Dementia, funded by Alzheimer's Society and Innovate UK, aims to encourage the development of technology that helps people with dementia stay independent for longer. About 150 million people are expected to be living with dementia by 2050, making such innovations crucial.The CrossSense technology is expected to cost around £50 a month per subscription, with the smart glasses potentially costing up to £1,000. However, the developers plan to make the technology more affordable over time. The team behind CrossSense plans to conduct a pilot study with smart glasses in people's homes later this year.Prof Julia Simner, who led the study, noted that participants with dementia could correctly identify 46% of household items without the glasses, increasing to 82% with the glasses. An hour after removing the glasses, the identification rate remained high at 78%.While experts praise the innovation, they also highlight the need for larger, more controlled studies to test the device's effectiveness and address ethical considerations regarding data collection and user consent.
