Aging

Ignoring meaningless platitudes like 'age is all in your mind', age is more than a number of years. 'You are as young as you feel' may be more apt because factors such as health, cognitive function and disability rates are important ways to measure age in all its dimensions.

International Institute for Applied Systems Analysis
population researchers Warren Sanderson and Sergei Scherbov seek to reorient the way demographers study population aging, providing a new toolbox of methodologies for demographers to better understand the impacts of an aging population on society, by measuring based instead on characteristics of people that change with age, including life expectancy, health, cognitive function, and other measures. 


The concept of permanent neurological injury is so 20th century.

Instead, there has been gradual recognition of the brain's potential for long-term regeneration and reorganization and so rehabilitations strategies are undergoing radical changes. The potential for five new translational interventions was examined in an recent Neurology Clinical Practice article.


It's said that being an astronaut is no longer a bold endeavor. The job works program nature of NASA and a no-risk approach to missions by government has meant a drop in prestige among the public. It used to be risky and that captured the public's imagination.

Some day, if presidents stop canceling the space programs of their predecessors, man may leave orbit again, and astronauts will gain some new respect, because even if the mission is successful astronauts are paying a price - their cells are aging faster in microgravity.


Engaging in some Do It Yourself projects or gardening can cut the risk of a heart attack/stroke and prolong life by as much as 30 per cent among the 60+ age group, indicates a new paper. 

They might seem like routine activities but they are as good as exercise, and more fun, which is ideal for older people who don't often do that much formal exercise, according to the scholars who based their findings on almost 4,000 sixty-year-olds in Stockholm, Sweden, who had their cardiovascular health tracked for around 12 years. At the start of the study, participants took part in a health check, which included information on lifestyle, such as diet, smoking, and alcohol intake, and how physically active they were.


A new paper says that babies can tell when something is wrong — as early as 18 months.


Neurons that process sensory information such as touch and vision are arranged in precise, well-characterized maps that are crucial for translating perception into understanding.  A new study finds that, in mice brains, the actual act of birth in mice causes a reduction in serotonin, triggering sensory maps to form.


A small pilot study has found that changes in diet, exercise and stress management may result in longer telomeres, the parts of chromosomes that affect aging - the first controlled trial to show that any intervention might lengthen telomeres over time.

Telomeres are the protective caps on the ends of chromosomes that affect how quickly cells age. They are combinations of DNA and protein that protect the ends of chromosomes and help them remain stable. As they become shorter, and as their structural integrity weakens, the cells age and die quicker.

In recent years, shorter telomeres have become associated with a broad range of aging-related diseases, including many forms of cancer, stroke, vascular dementia, cardiovascular disease, obesity, osteoporosis and diabetes.


New thinking about the evolutionary nature of biological aging will profoundly affect medical research on age-related diseases – here’s why.

Research into the role of proteins called sirtuins in enhancing longevity has yielded contradictory results from many different scientists - while it's been fine for mouse studies, weaning human babies on a diet near starvation isn't possible. As a result, the benefits of a low-calorie diet are accepted by people who want to believe it.
