A longitudinal study of 793 adults tracked vitamin D levels at an average age of 39 and brain‑scan biomarkers 16 years later. Participants with serum vitamin D above 30 ng/mL showed significantly lower tau protein accumulation, a key Alzheimer’s marker, while no link was found with amyloid‑beta. The association persisted after adjusting for age, sex and depression, but the study relied on a single baseline vitamin D measurement. Researchers caution that vitamin D may be a proxy for overall health rather than a direct neuroprotective agent.
The UK Medicines and Healthcare products Regulatory Agency (MHRA) has launched an investigation into several peptide clinics that are promoting unregulated, experimental peptide injections as medicinal treatments. Clinics are advertising products such as BPC‑157, Cortexin and Thymosin Alpha with claims...
Peptides—short chains of amino acids—are gaining popularity for weight loss, anti‑aging, and injury recovery. While prescription drugs like semaglutide and tirzepatide are FDA‑approved, most products marketed online are experimental, unregulated compounds such as BPC‑157, TB‑500, and CJC‑1295. Scientific reviews show...
Recent research identifies neuronal HDAC9 as a pivotal regulator of synaptic health and cognition during aging. The study shows that HDAC9 expression declines in the cortex of Alzheimer’s disease (AD) patients and aged mice, correlating with synaptic loss and memory...
A new molecular psychiatry study of 672 community‑dwelling older Asian adults found that higher depressive symptom severity is associated with accelerated epigenetic aging, especially measured by the second‑generation PC‑PhenoEAA clock (β = 0.087 per standard‑deviation increase; clinical depression raises PC‑PhenoEAA by 0.24 SD)....
Researchers applied a machine‑learning model to sleep‑EEG recordings from more than 7,000 participants, generating a “brain age” index that reflects how fast the brain appears to age. The analysis showed that a brain age ten years older than a person’s...
A new Science Weekly podcast examines the growing trend of alternating sauna sessions and cold‑plunge immersions, dissecting the scientific evidence behind claimed health benefits. Researchers discuss modest cardiovascular gains linked to regular sauna use and short‑term muscle recovery from cold‑water...
Garage Brain Science (GBS), a Taiwan biotech, announced new clinical collaborations to develop rapid, at‑home screening tools for early metabolic stress linked to prediabetes and structural abnormalities of the TDP‑43 protein associated with neurodegenerative diseases. The company is leveraging blood‑based...
