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.

Interacting with a therapeutic robot companion made people with mid- to late-stage dementia less anxious and also had a positive influence on their quality of life, according to a pilot study

PARO, a robotic harp seal, was used to investigate the effect of interacting with an artificial companion compared with participation in a reading group. PARO is fitted with artificial intelligence software and tactile sensors that allow it to respond to touch and sound. It can show emotions such as surprise, happiness and anger, can learn its own name and learns to respond to words that its owner uses frequently.
Scientists have a new theory as to why a woman’s fertility declines after her mid-30s: As women age, their egg cells become riddled with DNA damage and die off because their DNA repair systems wear out. Defects in one of the DNA repair genes, BRCA1, have long been linked with breast cancer and now also appear to cause early menopause.
