Scientists have recently conducted a structured narrative review of existing evidence to examine how selected animal- and plant-sourced foods may influence neurodevelopment and cognitive performance from early development through older adulthood. This review is available in Nutrients.

How common spices may improve gut, brain, and metabolic health

Researchers reviewed available literature, particularly studies conducted at the University of California–Los Angeles (UCLA) Center for Human Nutrition, to examine the effects of spices and herbs on human health. This review is available in Nutrition Reviews.

Why new Alzheimer’s drugs are dividing regulators worldwide

https://www.news-medical.net/news/20260531/Why-new-Alzheimere28099s-drugs-are-dividing-regulators-worldwide.aspx?utm_source=news_medical_newsletter&utm_medium=email&utm_campaign=alzheimer_s_disease_newsletter_4_june_2026 New Alzheimer’s drugs are raising hopes, but modest benefits, ARIA safety risks, high costs, and regulatory disagreements show how uncertain the path to meaningful treatment remains. A recent World Report published in The Lancet examines the evolving therapeutic landscape and regulatory hurdles surrounding Alzheimer’s disease (AD). Regulators debate whether the clinical benefits of new drugs outweigh their safety concerns and whether those benefits can translate into meaningful patient outcomes. This has led to conflicting approval decisions across countries. Scientists are now developing safer drugs that target broader disease mechanisms and testing them in people at high risk for AD before symptoms appear. Such efforts could advance precision medicine and help reduce the global burden of AD.

How the brain builds sentences, neuron by neuron Neural maps reveal the specialized cells that produce speech. By Max Kozlov

https://www.nature.com/articles/d41586-026-01922-w In the fraction of a second before a person speaks, their brain weaves together complex grammar, precise vocabulary and the underlying meaning of the language. Now, researchers have tracked the electrical crackle of individual brain cells in real time during unscripted conversations, capturing how sentences are built before a single word is spoken.

Is AI ruining our skills? Early results are in — and they’re not good Reliance on artificial-intelligence tools degrades the abilities of physicians and software engineers, studies show. By Mariana Lenharo

https://www.nature.com/articles/d41586-026-01947-1 As more professionals begin to rely on artificial-intelligence tools in their work, could their hard-earned skills atrophy? That possibility is a growing concern for medical specialists, computer scientists and other workers. Seventy per cent of nurses and 77% of physicians, for example, are worried about losing their skills because of over-reliance on AI systems, according to a survey of US health-care workers published earlier this month1.

Stem cells banish severe autoimmune disease for 15 years Two people were the first to receive the therapy for a condition that damages the spinal cord and optic nerve. By Rachel Fieldhouse

https://www.nature.com/articles/d41586-026-01925-7 A man and a woman with a rare and devastating autoimmune disease have been in remission for more than 15 years after receiving a stem-cell transplant1. The positive results, which were reported in Med, suggest that the experimental treatment warrants a larger clinical trial, say scientists.

Next-Generation CRISPR Tools Transform Gene Editing And Gene Therapy

https://www.news-medical.net/life-sciences/Next-Generation-CRISPR-Tools-Transform-Gene-Editing-And-Gene-Therapy.aspx Emerging gene-editing platforms are demonstrating that disease-causing mutations, aberrant gene expression, and even large-scale DNA insertions can be corrected without relying on error-prone DNA break repair pathways. Advances in base editing, prime editing, epigenome modulation, programmable DNA integration, and targeted delivery systems are bringing safer, more versatile, and clinically scalable genetic medicines closer to routine therapeutic use.
