Researcher João Pedro de Magalhães and colleagues are working on a new online resource: "We have developed a new web portal to integrate molecular, physiological ,and pathological age-related data that may be of interest. ... The Digital Ageing Atlas is a portal of changes covering different biological levels. There are currently portals for both humans and mice. The idea is to integrate molecular, physiological and pathological age-related data and create an interactive portal that serves as the first centralised collection of ageing changes and pathologies. ... It allows users to search and retrieve age-related changes at different levels, allowing a better understanding of the interplay between such changes and obtain new insights. We also think this will be an important new resource for modelling and for the systems biology of ageing and hope you will find it useful. Although so far we focused mostly on human aging, a preliminary mouse version of the portal is on-line already."
