A study published by researchers at the University of Illinois Chicago describes a new method for analyzing pyroptosis — the process of cell death that is usually caused by infections and results in excess inflammation in the body — and shows that process, long thought to be irreversible once initiated, […]

The blood-brain barrier wraps blood vessels where they pass through the central nervous system, controlling the passage of cells and molecules into and out of the brain. The blood-brain barrier becomes disrupted with age, allowing unwanted molecules into the brain, where they can spur chronic inflammation and dysfunction contributing to […]

70% of astronauts who spend time on the International Space Station (ISS) experience swelling at the back of their eyes, causing blurriness and impaired eyesight both in space and when they return to Earth.

With age, the immune system becomes every more overactive and inflammatory, reacting to signals created by the damaged environment of the body. This background of chronic […]

Mutations affecting growth hormone metabolism and insulin metabolism, and that lead to extended life, are comparatively well studied in mammals. The longest lived mice are those in which growth hormone receptor is knocked out. Unfortunately, this, like many interventions related to growth, nutrient sensing, and the like, produces a much […]

The practice of calorie restriction improves long-term health and slows near all aspects of aging assessed to date. In humans, the beneficial effects of calorie restriction on healthy people are larger than any enhancement technology is yet proven to supply; it remains to be seen as to how the first […]
