As the global population ages, effective strategies to attenuate or prevent neurodegenerative processes are becoming increasingly important. Gerobiotics, an emerging class of probiotic strains and their derived postbiotics, are considered promising geroprotective agents because of their potential to target fundamental mechanisms of aging, modulate the gut-brain axis, and attenuate age-related cognitive and functional decline. This review aims to synthesize existing evidence from preclinical and...

CONCLUSION: Plasma SVIP demonstrates significantly higher diagnostic accuracy than VCP for the detection of aMCI, suggesting its potential as a candidate blood-based biomarker pending large-scale pathophysiological validation.

Aging reshapes the architecture of human skeletal muscle, yet objective tissue-level markers that capture this process remain limited. We combined large-scale histology with deep learning to identify reproducible features of muscle aging and to test their biological relevance. We analyzed 974 hematoxylin-eosin whole-slide images from a population resource using a dual-attention convolutional neural network and an independent Mask R-CNN model to quantify nuclear size and density, verified by...

Aging is the primary risk factor for neurodegenerative diseases, characterized by a progressive decline in cellular homeostasis. Central to this process is the mammalian target of rapamycin complex 1 (mTORC1), a convergent integrator regulator of metabolism that integrates nutrient sensing with cellular growth. While essential for development, chronic mTORC1 hyperactivity, termed mTORopathy, emerges during aging, driving a deleterious cycle of mitochondrial dysfunction, neuroinflammation, and...

A new oral GLP-1 medication helped people with type 2 diabetes dramatically improve blood sugar control and lose weight in a major clinical trial. The results suggest that highly effective diabetes treatments may soon become available in a much more convenient pill form.

Researchers used genome editing to block the production of red pigments in lettuce, causing other beneficial plant compounds to build up instead. The lettuce continued to grow normally, pointing toward a new way to create crops with customized nutritional profiles.

A copper-based compound restored the brain’s ability to clear toxic Alzheimer’s proteins, dramatically reducing amyloid buildup and improving memory in laboratory experiments. The findings point to a potentially fast-tracked new treatment strategy because the drug has already been tested in humans for other neurological conditions.

AIs on their own found ways to exploit regulations and evade current safeguards

A new whey protein manufacturing technique could make protein shakes taste better and feel smoother in the mouth. Researchers traced unwanted bitterness to concentrated minerals and found a way to remove them without sacrificing the improved texture.
