Rejuvenating the Brain with Transplanted Astrocytes: A new study published in Stem Cell Research and Therapy has shown that rejuvenating the astrocyte niche in the aged brains of mice leads to improved nervous system function at both the cellular and organismal levels.

Vascular brainMetformin, Rapamycin, NMN, and Vascular Cognitive Impairment: A study published in Frontiers in Neurology has detailed how three well-known longevity-associated compounds affect vascular cognitive impairment (VCI) in a rat model that mimics arterial occlusion in human beings.

Fruits and Vegetables Linked to Fewer Cognitive Disorders: A meta-analysis published in Frontiers in Nutrition has found that intake of fruits and vegetables is negatively correlated with cognitive decline in older adults. Sixteen different studies were used for this meta-analysis, and not all of them measured fruit and vegetable comsuption the same way or measured the same endpoints.

Red grapesShort-Term Resveratrol Reverses Ovarian Aging in Mice: Researchers have shown that resveratrol reverses several features of ovarian aging in mice while activating most sirtuins and boosting mitochondrial health. In many mammals, including humans, ovarian aging is premature compared to other systems.

AI-Powered Novel Therapeutic Target Discovery: A new study conducted by Insilico Medicine in collaboration with leading aging research institutions has identified novel therapeutic targets for amyotrophic lateral sclerosis, a devastating age-associated neurodegenerative disease.

OrgansDifferent Tissues’ Proteins Age in Different Ways: An in-depth preprint published in bioRxiv has thoroughly described how separate tissues lose proteostasis in different ways. The researchers compared protein accumulation between old and young killifish, examining the brain, gut, heart, liver, muscle, skin, and testis.

Mild COVID Can Cause Protracted Neurological Problems: Researchers have shown that even mild SARS-CoV-2 infection can cause lingering neurological symptoms. These findings might shed light on the infamous “long COVID”. COVID survivors sometimes experience cognitive symptoms, such as “brain fog”, that can linger for months.

Standing mouseThe Importance of Mitochondria in Joint Health: Publishing in Aging, a team of Spanish researchers has found that changing the mitochondria of standard Black 6 mice, without any other modifications, leads to marked improvements in joint health.

Bioreactor-Grown Mitochondria for Potential Anti-Aging: Researchers from the University of Connecticut, Stanford University, Université Laval Quebec, and NSU Florida have helped test large-scale exogenous mitochondrial transplants in animal disease models and in-vitro human cells. The results suggest broad efficacy for targeting the immune system, brain, retina, liver, skin, and systemic anti-aging.

Diet and exerciseExercise and Healthy Diet Cannot Replace Each Other: In a large-scale study, scientists have shown that exercise and good diet affect mortality independently, showing that you need both to stay healthy. Exercise is good for you, and so is a healthy diet. Moreover, those are probably the only currently available interventions with a proven effect on healthspan and lifespan.

Fighting Muscle Atrophy with Gene Editing: In a new study published in Journal of Nanobiotechnology, researchers prevented muscle atrophy both in vitro and in vivo by delivering a CRISPR-Cas9 gene editing system packaged in engineered extracellular vesicles.

Old politicianPoliticians Live Longer Than Most People: By analyzing historical data, scientists have shown that politicians, an example of an elite group, have enjoyed longer than average life expectancy since about 1950.

Social Frailty Is Correlated with All-Cause Mortality: Scientists have shown that social frailty – a composite index based on income level, household status, and social activity – significantly affects all-cause mortality in the elderly, with poverty being the predominant factor.

GlutamineGlutamine Supplementation Has Anti-Aging Potential: A new study published in Frontiers of Pharmacology has shown that glutamine deprivation might speed up aging while glutamine supplementation reduces oxidative stress-induced senescence in mice.

Loss of IGF-1 May Contribute to Neurovascular Aging: Researchers publishing in GeroScience have reported that the age-related decline in IGF-1 levels is associated with neurovascular aging. However, given the weak correlations, even if there is a causal relationship, it is likely to be only one of many factors.

Future ClockEpigenetic Age Acceleration Is Correlated with Mortality: In an important step for the longevity field, scientists have found that epigenetic age acceleration, as measured by four popular methylation clocks, is correlated with aging and mortality in humans.

Acetyl-cholinesterase-inhibitors slow cognitive decline and decrease overall mortality in older patients with dementia: Among older people with dementia, treatment with these drugs was associated with a slower cognitive decline and with reduced mortality, after a mean follow-up of almost eight years.

Targeted Plasmalogen Supplementation in Cognitively Impaired Persons: Changes in cognition and mobility were statistically significant versus a random outcome. Baseline DHA-containing plasmalogen levels were not predictive of clinical response. DHA-plasmalogens were well tolerated at all dosages, and no adverse reactions were observed.
