Jonathan the tortoise is 194 and thriving - his genes may help explain why

So, what can a tortoise who has lived for 194 years teach us about ageing? A new study identified 287 unusual gene variants in Jonathan that may help protect against DNA damage, inflammation and cancer, while supporting healthy insulin regulation. Researchers also found that switches controlling genes involved in DNA repair and energy production have stayed remarkably stable compared with those of younger tortoises. Genes alone do not explain his extraordinary longevity, but Jonathan’s biology offers a fascinating glimpse of how nature can help bodies stay resilient.
