Fight Aging! provides a weekly digest of news and commentary for thousands of subscribers interested in the latest longevity science: progress towards the medical control of aging in order to prevent age-related frailty, suffering, and disease, as well as improvements in the present understanding of what works and what doesn’t work when it comes to…

To my mind far too much effort is expended on trying to figure out the epidemiology of the tiny fraction of humans who manage to live a fair way past one hundred years of age. For one, there just aren’t enough of them to generate truly robust data from which conclusions can be drawn. People…

Funding is pouring into the commercial development of the first rejuvenation therapies, largely meaning senolytic treatments at the present time, alongside various ways of upregulating beneficial stress responses in order to modestly slow aging. As this progresses, we will see an accompanying growth in advocacy for the treatment of aging as a medical condition. The…

Since ketosis is argued to be a component of the effects of calorie restriction, responsible in some part for the reliable benefits to health and longevity that result, some research groups have investigated ways to induce ketosis via treatment rather than via diet. This is a subset of broader efforts to produce calorie restriction mimetic…

Today’s open access paper is well worth reading through completely; the middle sections are a good consideration of how specific mechanisms and diseases in aging feed upon themselves to progress ever faster over time. Aging is a process of damage accumulation. The damage itself is comparatively simple; aging is complex because cellular biology is complex,…

14 Feb 2019 14 Feb 2019 Oglionucleotides that Interfere in Telomerase Activity Without Killing Cells Loading… Loading… It seems reasonable to think that sabotaging the lengthening of telomeres might prove to be the basis for a universal cancer therapy, capable of shutting down all cancers. Unfettered telomere lengthening is required by all cancers in order…

Hematopoietic stem cell transplant (HSCT) is, in essence, a way to replace a person’s immune system. These stem cells give rise to all of the immune cells in the body. There are numerous reasons why HSCT is a traumatic procedure, with a comparatively high risk of death, and thus only widely used for very severe…

Farming animals is morally dubious, to say the least, but we live in a world in which most people are accepting of this practice. That doesn’t make it right, and I think that this will change in the future. For now, however, anyone who finds farming animals for meat ethical should also consider it ethical…

The role of oxidized lipids in aging is often studied in the context of comparative biology, comparing different species with divergent life spans in order to try to identify the properties of cellular metabolism that are most influential on life span. It appears that the degree to which lipids are resistant to oxidative reactions is…

13 Feb 2019 13 Feb 2019 More on Fibrinogen and Blood-Brain Barrier Leakage in the Aging Brain Loading… Loading… The blood-brain barrier lines the blood vessels of the brain, and only very selectively allows passage of molecules to and from the brain. As is the case for all tissue structures, it fails with age. Molecular…
