The accumulation of zombie-like cells seems to accelerate aging and promote aging-related disease. Researchers are trying to figure out how.

Oxidative stress associated with aging damages ovarian cells in both humans and nonhuman primates.

While the findings contradict previous studies that have linked human herpesvirus 6 to the neurodegenerative disease, they do not eliminate the possibility of a relationship.

Genes related to the immune system stay active throughout the tree’s life.

Suppressing the natural age-related increase in neuronal excitation lengthens the lives of worms, and there are indications that the same may be true for mice and humans.

The researchers intend for the tool to eventually help doctors make treatment decisions.

Mutations within the MS4A gene cluster have been linked to changes in protein levels that affect disease risk.

Lucie Low, a project leader for Tissue Chips in Space, describes the experiments that are slated to blast off later this week.

The agency warns that plasma treatments costing thousands of dollars, which supposedly treat the infirmities of old age, have not been proven “safe or effective.”
