By now, most people are probably aware of the therapeutic value of stem cells, as they can become any other type of cell in the human body. One of their main duties, in fact, is to replace those other cells as they degrade. Once people reach an advanced age, however, even the stem cells themselves start to get old and nonfunctional - when the cells that are supposed to replace the other cells can't do their job anymore, age-related tissue problems start occurring. A team of researchers from the Buck Institute for Research on Aging in collaboration with the Georgia Institute of Technology, however, may be on the way to solving that problem. They have succeeded in reversing the aging process in human adult stem cells.  Read More

A new study raises questions about one of the favored theories of aging involving increasi...

A recent study suggests that, at least for worms, free radicals may not be the "bad guys" after all. It turns out that if you are a bacteria-eating worm of the species C. elegans, genetic modifications that raise your free radical levels don't have the negative effect expected, but instead serve to lengthen lifespan.  Read More

Nylstar has developed a new nanomaterial that is claimed to have moisturizing, protective ...

For as long as I can remember, keeping skin young and fresh has generally involved the liberal application of various moisturizing and nourishing creams with strange-sounding ingredients and an even greater number of anti-aging claims. Spain's Nylstar has managed to bind an important component of skin with 24K gold at a nanoscale level to create NYG nanoparticles. The new nanomaterial is then integrated with nylon fibers to make something called Nylgold dermawear, which is said to have a nourishing and protective effect on the skin of the wearer.  Read More

The aging process - it's undignified, unwanted, and many would say unnecessary. After all, the cells in your body are constantly replacing themselves - why can't they do it without causing progressive degradation of organs that lead to discomfort, weakness and death? Well, perhaps they can. Harvard scientists have discovered that by controlling certain genetic processes in mice, they can not only slow down the aging process, but "dramatically" reverse it throughout the body. It's a massive discovery, but it won't be able to be used in humans yet without some pretty scary consequences.  Read More

For many scientists who know about such things, the question isn’t whether the first person to live forever has been born, but how old they are. The basis for this belief is that, if a person can survive the next 20 or 30 years, then breakthroughs in biotechnology will easily allow them to extend their lifespan – not to mention their quality of life – to 125 years. From that point, the advances will keep coming to allow the prolonging of life indefinitely. One of the first steps towards such a reality has just been announced by a group of researchers who have discovered the first compound that activates an enzyme called telomerase in the human body.  Read More

The FDA has finally approved a miniature eye telescope that will aid sufferers of end-stag...

After five years, the U.S. Food and Drug Administration has finally given approval to an eye telescope that treats macular degeneration, the leading cause of blindness in the U.S. The Implantable Miniature Telescope (IMT) has been developed by VisionCare Ophthalmic Technologies, Inc. as part of Centrasight, a new patient care system which treats end-stage age-related macular degeneration (AMD).  Read More

Twendy-One helps out with a spot of cooking

Japan, like many other countries, faces a rapidly aging population sparking concerns about how the elderly will be cared for in their twilight years. Japan being Japan has turned to robotics with researchers developing robots to assist the elderly with everything from exercise and independent living to shopping. Twendy-One is the latest robotic helper to join the fray designed to support aging people in their daily activities.  Read More

Older drivers - Safe or unsafe?

The world's population is aging rapidly, with implications in numerous areas, not the least of which is that the number of male drivers over the age of 70 will double in the next 20 years, and the number of female drivers over 70 will treble. Does this pose a greater risk on the roads? A new in-depth report released today by the UK's IAM (Institute of Advanced Motorists contradicts the common assumption that older drivers are a danger on the roads, comprehensively proving that drivers over 70 are no more likely to cause crashes than any other driver, and are indeed, considerably safer than younger drivers.  Read More

The US$40,000 Robotic Bed

One of the stand-outs amongst a stellar field of automated and autonomous ingenuity on show at the IRex robotics expo in Japan this week was the Yurina Care Robot from Japan Logic Machine. Essentially a robotic bed, the 3.5 million Yen (around US$41,000) Yurina reconfigures electronically, on-the-fly, can be controlled by the user or a carer into many different configurations, has four separate sections which can all be angled differently, and can lift and make comfortable, a disabled person of up to 120 kilograms in almost any position. It gets along at 4kmh, can lower you into the bath and get you out again without giving anyone a hernia and comes with a range of optional extras you could only dream about if you are in need of such a device.  Read More

Researchers at Mount Sinai School of Medicine have unraveled a molecular puzzle to reveal why a lower-calorie diet slows the development of some age-related conditions such as Alzheimer’s disease, as well as the aging process itself. In their search for an answer they discovered that it doesn’t seem to matter how the diet is restricted – whether fats, proteins or carbohydrates are cut – to produce protective effects against aging and disease.  Read More
