Aging

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.

Art is forever was true in the case of internationally renowned sculptor Mary Hecht.

Despite an advanced case of vascular dementia, Hecht was able to draw spur-of-the moment and detailed sketches of faces and figures, including from memory and her case study shows that the ability to draw spontaneously as well as from memory may be preserved in the brains of artists long after the deleterious effects of vascular dementia have diminished their capacity to complete simple, everyday tasks.


Biotechnology company Quantec Ltd has presented the results of its US clinical trial of its patented complex of bioactive milk proteins product - called IDP - which was conducted at clinical research facility in California and completed in February of 2013.

IDP was the active ingredient in a specially formulated skin cream that went head-to-head in a double blind study against a premium, US-based clinical brand of acne treatment cream (containing 2% salicylic acid plus retinal). Results were presented at the New Zealand Dermatological Society Annual Meeting in Coolum, Australia last week.
