Brain Cells Observed Summoning a Memory
Scientists have for the first time recorded individual brain cells in the act of summoning a spontaneous memory, revealing not only where a remembered experience is registered but also, in part, how the brain is able to recreate it.

Liberal creationism and transhumanism
Overcoming nature through technology may turn out to be more empowering for academics and public policy makers than the average individual as it will generate a never ending stream of excuses (new or revised concepts of “market failure” and “public goods”) for government intervention.

Telomerase active protein region's structure revealed
Researchers at The Wistar Institute have deciphered the structure of the active region of telomerase, an enzyme that plays a major role in the development of nearly all human cancers.

Exercise and calorie restriction: Common mechanisms of longevity promotion?
The mitochondrial changes caused by exercise are very similar to the physiological consequences of calorie restriction (CR), an intervention that is known to extend lifespan in model organisms and to delay age-related disease in humans. This fits in nicely with other recent observations connecting exercise and CR.

A mitochondrial gene that slows brain aging
Researchers have delayed the onset of neurological decline in mice, by introducing a human gene involved in mitochondrial transcription. The paper provides further evidence that oxidative damage is an important causative factor in age-related deterioration of the brain.

Exercise mimetics? The benefits of working out, in pill form.
As a biologist of aging, one question I get asked frequently is: “What pills should I be popping?” My answer: Supplements are of questionable value, but the old advice is still good advice: Avoid tobacco, eat a reasonable diet, and get plenty of exercise. After all, I usually jest, they’re never going to turn exercise into a pill. Until, you know, they do.

Telomere dysfunction provides new biomarkers of aging
It would be nice to have access to a biological measurement (or series of measurements) that allowed us to determine an individual’s age. Until we have such a tool, questions like “how rapidly is this individual aging?” are meaningless. A new study identifies a new class of biomarkers: proteins produced by cells with shortened telomeres.

Can Novamente’s virtual dogs make a Nintendog look dumb?
A Nintendog’s behaviors were scripted, its personality restricted to a handful of breeds. On the other hand, Novamente, a company that aims eventually to develop a super-smart artificial intelligence (AI), says that its current technology will make such limitations remnants of the past.

Inflammation, aging and cancer
Centenarians tend to have less robust inflammatory responses. The reduction in inflammatory capacity isn’t large (not even two-fold at the level of primary cytokine output, though quantifying the difference depends ultimately on which endpoint one is measuring), so this gives credence to the idea that tailored anti-inflammatory drugs — perhaps targeted to individual tissues -- could help slow age-related onset of cancers.

Dietary supplements induce neurogenesis after stroke
