News of "fracture putty," an evolution in the use of scaffold material for bone regeneration: recent studies "show promise to significantly shorten the healing time and revolutionize the course of fracture treatment. ... Healing of critical-size defects is a major challenge to the orthopedic research community. Large-bone defects must be stabilized and necessitate technologies that induce rapid bone formation in order to replace the missing tissue and allow the individual to return to rapid function. To date, no single material can suffice. ... In our experiences with large animal models, following the guidelines established by our animal care and use...

As you might imagine, exercise affects the behavior of muscle stem cells: "researchers determined that an adult stem cell present in muscle is responsive to exercise, a discovery that may provide a link between exercise and muscle health. The findings could lead to new therapeutic techniques using these cells to rehabilitate injured muscle and prevent or restore muscle loss with age. Mesenchymal stem cells (MSCs) in skeletal muscle have been known to be important for muscle repair. ... Since exercise can induce some injury as part of the remodeling process following mechanical strain, we wondered if MSC accumulation was a...

As I mentioned the other day, there are more economic benefits to enhanced human longevity than just the obvious ones. Some of these benefits emerge from systematic changes in the interactions and relationships that make up society: the willingness to consider longer time horizons changes the way in which people value all sorts of things, both in the present and for the future. If fifty years from now is someone else's problem in your eyes, you are unlikely to be a good steward of fifty-year bonds - but if you are going to be alive, vocal and very much in...

Osteoporosis is a pervasive issue in the old, and potential methods for reversing its effects are welcome: scientists have "developed a novel technique to enhance bone growth by using a molecule which, when injected into the bloodstream, directs the body's stem cells to travel to the surface of bones. Once these cells are guided to the bone surface by this molecule, the stem cells differentiate into bone-forming cells and synthesize proteins to enhance bone growth. ... There are many stem cells, even in elderly people, but they do not readily migrate to bone. Finding a molecule that attaches to stem...

It is not unreasonable to regard a cell as a machine that is constantly rebuilding itself - organelles and protein machinery are constantly torn down and replaced. It is also not unreasonable to regard tissue as a collection of cells that is constantly rebuilding itself: cells destroy themselves or are destroyed by watchdog systems, and new cells are created to replace them. This sort of thing happens rapidly indeed in some parts of the body, such as the blood and stomach lining, but there are portions of your nervous system where cells will never be replaced under normal circumstances -...

An advance in the methodologies of nerve repair: "scientists believe a new procedure to repair severed nerves could result in patients recovering in days or weeks, rather than months or years. The team used a cellular mechanism similar to that used by many invertebrates to repair damage to nerve axons. ... We have developed a procedure which can repair severed nerves within minutes so that the behavior they control can be partially restored within days and often largely restored within two to four weeks. If further developed in clinical trials this approach would be a great advance on current procedures...

Researches find another way in which the brain declines with age: "New findings [reveal] a novel mechanism through which the brain may become more reluctant to function as we grow older. ... researchers examined the brain's electrical activity by making recordings of electrical signals in single cells of the hippocampus, a structure with a crucial role in cognitive function. In this way they characterised what is known as "neuronal excitability" - this is a descriptor of how easy it is to produce brief, but very large, electrical signals called action potentials; these occur in practically all nerve cells and are...
