Hourglass X
The tenth Hourglass blog carnival is up: "As we age, we all suffer from some level of neurodegeneration, though in most cases this falls below the threshold of a clinical pathology. Slow chronic change isn't the only form of age-related brain damage: let's not forget about strokes, which can wipe out otherwise healthy neurons in macroscopic regions of the brain. While the risk factors for stroke and neurodegeneration are distinct, therapies might ultimately be quite similar - since in both cases, the goal is to regrow neurons to replace those that have been lost. At Brain Stimulant, Mike tell us about a clinical trial that will use stem cells to treat stroke ... Colin Farrelly of In Search of Enlightenment has submitted two long, thoughtful articles, the first about the clinical and social importance of tackling aging, the second about the cognitive biases that affect the way we think about risk and the significance of aging as a cause of mortality ... In a rational world, aging research would be at the forefront of a global collaborative initiative to improve the health and economic prospects of today's aging populations (and all future generations). But humans are not rational. We suffer many cognitive biases."
