India, June 30 -- The Axiom-4 mission crew, including Indian astronaut Shubhanshu Shukla, has begun active research aboard the International Space Station (ISS) following their successful arrival. Their initial focus includes "microgravity acclimation" as they engage in a series of experiments aimed at advancing medicine, agriculture, and space science.

Among the key investigations is the "Cancer in LEO-3" study, led by veteran astronaut Peggy Whitson. This research explores how cancer cells behave in microgravity, with a specific focus on tumour organoids and a new model of triple-negative breast cancer. Scientists are analysing how these cells respond to drug treatments in space, with the objective of confirming previous findings and p...
