As mysterious bird declines crop up in the Amazon and beyond, scientists suspect climate change may be to blame

Increased life expectancy brought about by improved healthcare and lifestyle has heightened the challenge of neurodegenerative disorders like Alzheimer's disease (AD) and other age-related disorders. Neurodegeneration is known to be accompanied by loss of memory, changes in brain morphology, and neuroinflammation, and multiple factors contribute to the progression and pathogenesis of the condition. Of these factors, metabolic dysregulation is known to influence the process, but the precise...

To investigate the relevance of small RNAs to human longevity, we pursued three goals: (a) to validate epigenetic (small RNA) factors underlying survival of older adults, (b) to develop and validate prediction models of survival for potential clinical application, and (c) to identify plausible druggable targets prolonging longevity. We evaluated 828 small non-coding RNAs-687 microRNAs (miRNAs) and 141 piwi-interacting RNAs (piRNAs)-in baseline plasma from 1271 community-dwelling older adults (≥...
