Widely prescribed blood pressure drugs linked to 33% higher kidney risk in type 2 diabetes
A widely prescribed blood pressure drug was associated with a 33% higher risk of serious kidney problems in people with type 2 diabetes, even when they were already taking kidney-protective medications. The surprising finding is prompting researchers to question whether DCCBs are always the safest second-line choice for diabetic kidney disease.
Tiny robots powered by light can hunt down and collect bacteria
Researchers have built microscopic, light-driven robots that can rapidly navigate through liquid, collect bacteria, and deposit them in chosen locations. These tiny “cleaners” could open new possibilities for manipulating cells and microbes with remarkable precision.
Mysterious waves sweeping across your brain may help turn sensory chaos into what you see
Traveling electrical waves sweeping across the brain may help determine what we notice, predict what comes next, and construct our internal picture of the world. Researchers now argue that these waves aren't just background activity—they could be a core computational engine behind perception and memory.

GLP-1 receptor agonists for Alzheimer's disease: Lessons from trials and translational challenges
Alzheimer's disease (AD) is a multifactorial disorder that requires combined therapeutic strategies beyond amyloid clearance. Although GLP-1 receptor agonists show strong mechanistic rationale and supportive epidemiological signals for neuroprotection, large randomized trials in symptomatic AD have yielded negative clinical outcomes and do not support the therapeutic use in AD.
The nutrition-sleep-circadian axis in age-related neurodegeneration: Cellular mechanisms, metabolic dysfunction, and neuroprotective interventions
Advanced age is accompanied by progressive metabolic, nutritional, mitochondrial, and neuroimmune dysregulation, which may increase susceptibility to neurodegenerative disorders such as Alzheimer's disease (AD) and Parkinson's disease (PD), highlighting the need to identify modifiable mechanisms that influence disease initiation and progression. Increasing evidence indicates that nutrition, sleep, and circadian rhythms function as an interconnected biological network regulating metabolic...
Autophagy as a mechanistic link between physical exercise and Alzheimer's disease
Alzheimer's Disease (AD), the most prevalent cause of dementia worldwide, is a neurodegenerative disorder that currently has no cure. A growing body of evidence suggests that physical exercise is a potential non-pharmacological strategy in the treatment of AD. Recent findings highlight the involvement of autophagy in the modulatory actions of physical exercise for AD. Here, we present a narrative review of the current knowledge on how exercise impacts AD, specifically focusing on its regulation...
Translating cellular aging clocks into disease risk prediction
Ding et al. mapped over 7,000 plasma proteins to more than 40 cell types and developed machine learning aging clocks across 60,000 individuals, demonstrating that cell-type-specific biological aging is heterogeneous, measurable from blood alone, and powerfully predictive of neurodegenerative disease, cancer, and mortality up to 15 years before clinical onset.¹.
Multimodal brain cell atlas across the adult macaque lifespan
High-throughput single-cell omics of non-human primate brain tissue provides a powerful platform to investigate the molecular basis of brain aging. Here, we present a comprehensive transcriptomic and chromatin accessibility atlas of 2,955,873 nuclei from eight brain regions of 23 female cynomolgus macaques spanning the adult lifespan, including exceptionally old individuals. Our analyses reveal dynamic, cell-subtype- and region-specific age-related changes in core brain functions, including...
