Scientists decode new avenues for research on healthy ageing

• New mechanistic insight into tissue ageing: support ("niche") cells around stem cells age faster than the stem cells themselves, and may be the true "weak link" in regenerative decline.
• Work done at Agharkar Research Institute (ARI), Pune, an autonomous institute of DST, using Drosophila melanogaster ovary as a model.
• Relevant for UPSC under GS-III (Sci & Tech: biotechnology, R&D) and feeds into the global WHO UN Decade of Healthy Ageing 2021-2030 agenda.
