Biophysical Society Feb 22 2026 As space agencies prepare for human missions to the Moon and Mars, scientists need to understand how the absence of gravity affects living cells. Now, a team of researchers has built a rugged, affordable microscope that can image cells in real time during the chaotic conditions of zero-gravity flight-and they're making the design available to the broader scientific community. The research, previously published in npj Microgravity , will be presented at the 70th
