Intestinal bacteria
Transferring microbiota from young to aged mice helped to restore molecular signaling necessary for proper intestinal function and improved the regenerative capacity of intestinal stem cells [1]. Everyday companions Bacteria, viruses, and other microbes are well-known as agents that cause disease and should be avoided. However, the microbes that make us sick, while more noticeable,...
Sleep problems
A new study links sleep loss to the thinning of the myelin layer, which slows signal transmission in axons. Restoring cholesterol homeostasis reverses the damage [1]. Sleep loss hurts myelin Sleep quality is a strong extrinsic determinant of longevity [2]. Not only does sleep loss affect cognitive function [3], it has also been linked to...
Natural killer cells
In Aging Cell, researchers have described why older natural killer (NK) cells lose their ability to eliminate harmful cells and a potential treatment for this decline. Judgment and ability At the cellular level, there is no due process. Natural killer (NK) cells judge other cells' guilt or innocence by their surface proteins. They ruthlessly exterminate...
Optic nerve
Life Biosciences has announced that its trial of cellular reprogramming aimed at two age-related vision diseases has received a go-ahead from the FDA. We spoke with the company’s CSO to get more details. Life Biosciences, the biotech company based on Harvard professor David Sinclair’s research into cellular reprogramming, stunned everyone last year by announcing that...
Researchers publishing in Nature Aging have described how mitochondrial stress is a key part of why senolytics are effective. Finding targeted effectiveness What Are Senolytics? Senotherapeutics for Senescent CellsSenolytics work by targeting one of several pro-survival pathways that senescent cells use to evade apoptosis and cling onto life. One of the challenges in dealing with...
Vitamins and supplements
A recent study analyzed data from over 15,000 participants and their intake of 11 vitamins, and the results suggested that higher vitamin intake, particularly of Vitamins C and B2, is associated with slower biological aging [1]. Beneficial molecules One of the easiest and most accessible ways to improve health and lifespan is to consume a...
