A new study suggests that microbiome remodeling is a mechanism behind age-related cognitive decline, with one particular bacterial species identified as the likely culprit. In mice, antibiotics seem to reverse this effect [1]. The gut-brain axis and the microbiome Memory decline is a common and debilitating feature of aging, but its mechanisms remain poorly understood....

In a new study, researchers have vitrified mouse brain slices and then a complete brain with encouraging results: upon rewarming, much of the neuronal function was preserved [1]. The bumpy road to cryopreservation Successful cryopreservation is a coveted prize in medicine, as cryopreserving organs and tissues can make transplantation more accessible. It is also a...

Scientists have found that the ratio between poly- and monounsaturated fatty acids affects the viability of T cells as well as both humoral and anti-tumor immunity [1]. The iron death Some fats are broadly recognized as healthy while others are considered unhealthy, but the reality might be more complicated than that. Poly- and monounsaturated fats...

Scientists have discovered that ATP deficiency disrupts dopamine processing in synapses, leading to the accumulation of the harmful protein species that characterize Parkinson’s disease. ATP supplementation helps, but the road to the clinic might be long [1]. Parkinson’s and dopamine Parkinson's disease is defined by two hallmarks: the death of dopamine-producing neurons in a midbrain...

Cellular reprogramming is one of the technologies most associated with longevity. The field was created in 2006, when Shinya Yamanaka showed that a cocktail of four transcription factors, commonly known as OSKM, can cause de-differentiation and massive rejuvenation of a cell, creating an iPSC (induced pluripotent stem cell). About a decade later, partial reprogramming was...

João Pedro de Magalhães, professor at the University of Birmingham, is known as a prominent geroscientist who has been in the field forever, enriching it with top-tier research. He is also a skilled longevity advocate who has long taken interest in the ethics of longevity, first offering his perspective as far back as 2003. Prof....
