Changes in Gut Microbiomes of Astronauts May be Linked to Bone Loss

In space, the bone density of both the human astronauts and rodent variety decreases. Scientists published this study on April 19th, 2023, in the journal Cell Reports. It says that alterations to the gut microbiomes of space travelers may be linked to this bone loss.

Hair-Coloring Stem Cells in the Hair Germ Compartment Trigger Pigmentation

Some stem cells have a special capacity to mobilize among growth compartments in hair follicles; however, they get stuck with age in people. Hence, they lose their capacity to mature and retain hair color, as per new research.
