Proteomic ageing clocks are emerging tools that estimate biological age from protein abundance patterns. Most models are developed using blood capturing inflammatory, metabolic, and extracellular proteins, including secreted signalling factors. Large-scale plasma studies now predict chronological age, disease risk and mortality, but muscle-related models remain indirect, relying on organ-enriched circulating proteins rather than biopsy-derived skeletal muscle clocks. We review current proteomic...

Superconducting cables connect quantum bits on different chips, but improvements are still needed

Study adds to mounting evidence that traumatic experiences can negatively impact health years—or even decades—later
