Aging

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.  

Sunshine is out. If you aren't slathering yourself in SPF 150 chemicals to keep it off of you, you're going to get skin cancer and no one will feel bad.

It's not that simple. As we grow older our bones become more fragile and a team of researchers have shown that this bone-aging process can be significantly accelerated through deficiency of vitamin D - which we naturally get from sunshine.

Vitamin D deficiency is a widespread medical condition that has been linked to the health and fracture risk of human bone on the basis of low calcium intake and reduced bone density. Working at Berkeley Lab's Advanced Light ALS , the international team demonstrated that vitamin D deficiency also reduces bone quality.  


Gerovital H3, one of the "fountain of youth" miracles drugs that crop up once a generation, was banned in the United States in 1982, but the alternative medicine crowd that never let go of homeopathy after hundreds of years is reviving it. Anti-aging and longevity clinics now promote Gerovital H3 in pill form and as intravenous infusions.

Gerovital H3 is the dental anesthetic procaine hydrochloride (novocaine) but in the 1950s it was abused, unsurprisingly, by the Hollywood elites who gravitate toward fad diets and miracle treatments.

We constantly grow new skin and shed the old but no one is sure exactly how it works. New research says they may provide the answer. 

Engineers and biologists at the University of Sheffield say a recent hypothesis - that skin has 'sleeping' stem cells which can be woken up when required - best explains how our skin constantly regrows. The research, conducted by The Procter&Gamble Company (P&G), makers of Olay, and the University of Sheffield and published in Nature Scientific Reports, may have implications for combating the effects of aging.
