A recent study from Stanford University School of Medicine demonstrates the partial restoration of brain function in old mice with infusions of cerebrospinal fluid from younger mice.
Since the development of technologies that have allowed humanity to outlive the “normal” period an organism is fit to survive in the natural world, the tragedy of old age and decrepitude has frustrated researchers and driven them to seek out a root cause. Progress has been achieved, for the most part, by addressing the discrete age-related pathologies; however, taking a first-principles approach focused on temperature has allowed researchers to investigate a basic temperature-dependent facet of aging and perhaps affect an underlying driver of many, if not all, age-related phenomena.
Thinking of biological aging as analogous to a clock, research has given us two distinct avenues of lifespan-extending intervention: the clock can be either slowed down or wound back. Most research has with dealt the former, but the latter is very promising—especially for those whose clock has been winding for some time.
Obesity is highly correlated with and thought to contribute to an increased incidence of heart disease, stroke, type 2 diabetes, and certain cancers and is rapidly becoming the most prevalent driver of age-related pathologies in the modern world. The availability of novel pharmaceutical interventions might provide treatment to the increasingly common condition of intractable obesity.
Can vaccines be used to fight age-related disease and, ultimately, to extend lifespan? Research published in Nature Aging suggests that such a promising strategy could be a reality.
When analyzed, the hippocampus, a region of the brain highly involved in learning and memory, showed increased neurogenesis in mice given access to running wheels for 28 days. In line with the increased cellular proliferation in the hippocampus, sedentary mice treated with “runner” plasma showed improved memory and cognition when assessed via standard behavioral tests.

This retrospective case-control study revealed several drugs to be associated with decreased incidence of developing AD; sildenafil was by far the most promising candidate.
Research has uncovered evidence that adipose cells are highly susceptible to senescence, an irreversible state of non-proliferation, and the accumulation of senescent cells with age leads to the senescence-associated secretory phenotype (SASP)—a deleterious inflammatory condition thought to be a critical driver of age-related diseases. Obesity and age are top risk factors for developing type 2 diabetes, and it would seem that therapies aimed at reducing SASP would be an ideal approach to improve this condition.
In 1935 Clive McCay published a paper demonstrating the pro-longevity effects of caloric restriction that would come to shape the future of longevity research. In McCay’s study, a simple 30% reduction of normal caloric intake was shown to impart robust gains in...
