Vitamin D Deficiency Causes Death, New Study Finds

Vitamin D deficiency increases mortality risk and raising levels even slightly could decrease the risk, researchers examining data from the UK Biobank have found.

Why centenarians consistently present a younger epigenetic age than their chronological age

One of the hallmarks of aging is epigenetic alterations, which comprise the epigenetic drift and clock at DNA methylation level. In a new study published in Aging, researchers Antoine Daunay, Lise M. Hardy, Yosra Bouyacoub, Mourad Sahbatou, Mathilde Touvier, Hélène Blanché, Jean-François Deleuze, and Alexandre […]
