Ai, a female chimpanzee at Kyoto University's Ai Project famed for numeracy, color naming, and painting, died at 49 from old age and organ failure, surrounded by staff; arriving in 1977 from West Africa, she helped drive decades of primate cognition research.
A WHO-commissioned meta-analysis of data on more than a million women finds no strong evidence that menopause hormone therapy (MHT/HRT) increases or decreases dementia risk. Most studies are observational with inconsistent, low-certainty results; one randomized trial suggested a possible risk with estrogen-only MHT after age 65, but certainty is low. The findings align with the 2024 Lancet Commission and FDA reassessment, and researchers call for more high-quality studies—especially in premature menopause—to clarify MHT’s role in cognitive health.
The article introduces a 5-day Brain Health Challenge emphasizing the importance of healthy habits like proper sleep, physical activity, social connection, and nutrition to improve and maintain brain health, reduce the risk of cognitive decline, and promote long-term brain resilience.
A Rutgers University study reveals how the human brain integrates fast and slow neural signals through white-matter pathways, influencing cognitive performance and linked to genetic and molecular features, with implications for understanding brain disorders.
Recent research indicates that moderate, structured gaming can enhance cognitive functions such as attention, multitasking, and learning, with benefits most notable during short, varied sessions. Excessive gaming, however, may diminish these benefits, emphasizing the importance of moderation and diversity in gaming habits.
The article explores how time-space synaesthesia affects the author's perception of the new year, making it a physical experience, and discusses the cognitive advantages and neurological basis of this condition, highlighting its influence on memory, time organization, and cultural differences.
A long-term study of the 1946 British Birth Cohort found that maintaining a high-quality diet from childhood through adulthood is associated with better cognitive abilities and a lower risk of dementia in older age, emphasizing the importance of lifelong nutrition for brain health.
Research shows that certain types of video games, especially real-time strategy and action games, can enhance brain processing, attention, and even slow aging, but moderation and variety are key for cognitive health.
Playing video games can enhance cognitive skills by practicing complex tasks in simulated environments, offering benefits beyond traditional simple brain games.
Research suggests that music lessons do not directly boost intelligence but instead reveal pre-existing traits like curiosity and discipline; personality and socioeconomic factors largely explain who takes music lessons and their academic success, with music offering benefits in joy, expression, and attention rather than cognitive enhancement.
A study in the Journal of Psychopharmacology found that frequent cannabis use in older adults causes specific temporary cognitive declines, especially in processing speed and executive function, despite strong subjective intoxication feelings. The research highlights nuanced effects, with some cognitive functions unaffected or even improved, and emphasizes the need for further research on age-related differences and long-term impacts.
Scientists discovered that losing a small, critical segment of myelin disrupts brain communication by impairing the transmission of signals between the cortex and thalamus, which can lead to cognitive issues similar to those seen in Multiple Sclerosis. The study highlights the importance of myelin in maintaining the structure of neural information transfer and suggests potential avenues for future recovery strategies.
The article argues that as AI surpasses human capabilities in reasoning and decision-making, the true challenge shifts from AI's intelligence to human responsibility and accountability, emphasizing the importance of remaining cognitively present and vigilant to ensure ethical and responsible use of AI systems.
The article explores how different numeral bases, such as base-10 and base-60, influence our thinking, language, and culture, affecting how we learn, process, and communicate about numbers, with implications for education, cross-cultural collaboration, and everyday decision-making.
Recent experiments demonstrate that chimpanzees are capable of rational thought, changing their beliefs based on new evidence, similar to humans.
