Scientists at the U.S. Naval Research Laboratory (NRL) have completed a spaceflight biology investigation aboard the International Space Station (ISS) that reveals how microgravity fundamentally alters microbial metabolism, limiting the efficiency of biological manufacturing processes critical to future long-duration space missions. The findings were recently published in the journal npj Microgravity.
Scientists at MDI Biological Laboratory use the fast-aging African turquoise killifish to uncover how a widely prescribed class of drugs helps protect the aging kidney. The study published by Kidney International establishes the fish as a powerful model for kidney aging and shows that SGLT2 inhibitors preserve capillaries, maintain cellular energy balance, and reduce inflammatory changes during aging—offering a mechanistic basis for the vascular-protective effects of SGLT2 inhibition during renal aging.
Skeletal muscle stem cells in hibernating Syrian hamsters preserve their ability to function by suppressing their activation during the hibernation period, a research team led by Hiroshima University has shown. This insight may lead to a broader understanding of the maintenance of muscle tissue under prolonged low temperature conditions and may eventually lead to therapeutic applications.
