Silly Walking for Serious Exercise

Researchers have shown that a particular walking style that many people immediately recognize can count as high-intensity exercise [1]. Does exercise have to be boring? In the fight against aging,

Targeting Cdc42 Improves Stem Cells in Old Mice

Researchers publishing in the Nature journal npj Regenerative Medicine have zeroed in on a major reason behind stem cell exhaustion and determined that inhibiting it has significantly rejuvenative effects. A

Senescent Cells Harm Muscle Regeneration in Mice

New research published in Nature has shown that senescent cells hamper muscle regeneration through inflammation and fibrosis [1]. Cellular senescence is one of the hallmarks of aging. However, there is

Changes To The Lamina Contribute To Heart Weakness

A paper just published in Nature Aging has explained how changes to the lamina contribute to heart weakness in model organisms. A protective enclosure for genetic stability Lamin proteins enclose

Transcriptome-Wide Organization Changes in Aging

In a new study published in Nature Aging, researchers have shown that aging is associated with a decreased expression of long transcripts over multiple tissues across several animal species [1].

Fighting Osteoporosis Through Cellular Signaling

A paper published in Experimental Gerontology has detailed how a bacterially derived compound may be useful in fighting osteoporosis. Osteoblasts and osteoclasts Osteoblasts are cells that build bone, and osteoclasts

Obesity Shown to Affect Brain Aging in Mice

Research published in Immunity & Ageing has shown that obesity has significant, aging-associated effects on behavior and immunity in the brains of mice. Known effects on humans and mice The researchers introduce this study by discussing human studies. It is well known that obesity is a

NAD+ Supplement Protects Intestines from Alcohol in Mice

Scientists have shown that the NAD+ precursor nicotinamide riboside (NR) alleviates symptoms of leaky gut caused by ethanol consumption in mice by improving mitochondrial function [1]. Leaky gut drives inflammation The permeability of the epithelial intestinal barrier is known to increase with age. The resulting condition,

The Hallmarks of Aging’s Original Authors Offer a Fresh View

The year 2023 started with the publication of two remarkable review papers in Cell and Cell Metabolism by researchers addressing the hallmarks of aging and their interplay with the hallmarks of cancer [1,2]. These papers were authored by the same team that published the original 2013

Aubrey de Grey on LEVF and Robust Mouse Rejuvenation

Dr. Aubrey de Grey is a legend in the longevity field who has been steadfastly promoting the idea of life extension since well before it became mainstream. While with SENS Research Foundation, de Grey made significant contributions to geroscience, and at Longevity Summit Dublin last year,

Gene Therapy to Induce Epigenetic Reprogramming

A preprint published in bioRxiv by scientists working at Rejuvenate Bio has described how gene therapy that allows for OSKM expression can be used to increase the lifespans of mice. A new handle on old problems The researchers begin this study with a discussion of the

Targeting Cdc42 Improves Stem Cells in Old Mice

Researchers publishing in the Nature journal npj Regenerative Medicine have zeroed in on a major reason behind stem cell exhaustion and determined that inhibiting it has significantly rejuvenative effects. A protein that suppresses stem cells In both humans and mice, the protein Cdc42 increases with aging.

Senescent Cells Harm Muscle Regeneration in Mice

New research published in Nature has shown that senescent cells hamper muscle regeneration through inflammation and fibrosis [1]. Cellular senescence is one of the hallmarks of aging. However, there is a growing understanding that, just like aging itself, senescence is a complex and heterogeneous phenomenon [2].

Fighting Osteoporosis Through Cellular Signaling

A paper published in Experimental Gerontology has detailed how a bacterially derived compound may be useful in fighting osteoporosis. Osteoblasts and osteoclasts Osteoblasts are cells that build bone, and osteoclasts are cells that consume it. These two processes happen consistently and naturally in the human body.

Short Bouts of Vigorous Activity May Reduce Mortality Risk

In a study published in Nature Medicine, scientists have shown that short bouts of everyday vigorous physical activity, such as stair climbing, are associated with a considerable reduction in mortality risk, especially in cardiovascular mortality [1].
