Bacteriophages
Researchers publishing in Nature Microbiology have determined that the viruses populating the intestines of centenarians are slightly different from those of the merely old. Viruses for bacteria, not people We have written previously about a study showing that centenarians have youthful bacterial gut compositions (enterotypes) similar to those of younger people. This study looks more...
Elderly intestines
Research published today in Nature Aging has illustrated how the gut microbiomes of the longest-lived people are more likely to have bacterial populations associated with youth. A known difference This is far from the first study showing a connection between a healthy, youthful microbiome and enhanced longevity. In most people, the gut microbiome gradually transitions...

Scientists publishing in Nature have found that compounds produced by some types of gut bacteria can influence dopamine levels in the brain and, as a result, might influence motivation to go on a morning run [1]. We’ve got company We tend to think of ourselves as single organisms, but every human body serves as a...

According to a new study, the age-related increase in intestinal permeability that drives inflammation can be alleviated by inhibiting the enzyme arginase, a regulator of nitric oxide production [1]. Gut feeling While age-related sterile inflammation (inflammaging) is considered one of the hallmarks of aging and a major cause of age-related diseases [2], scientists still don't...

Researchers publishing in Nutrients have shown that adding a strain of lactic acid bacteria to the gut flora of older, memory-impaired people partially alleviates their memory problems. A specific anti-inflammatory bacterium The researchers begin their paper by noting that mild cognitive impairment (MCI) is associated with memory loss and is frequent precursor of Alzheimer's disease...
Intestines
In ESC Heart Failure, researchers have commented about the correlation between a poor gut microbiome and aging of the heart [1]. The microbiome is important in aging Research increasingly suggests that the quality and composition of the gut microbiome may play a role as important as exercise on health. The gut microbiome is a living...
