Putting it on ice – Extremely low temperatures are also used in cryotherapy -- a medical treatment that has gained currency with a number of international sports teams. Here, French soccer player Franck Ribery is immersed in a cryotherapy tank, subjecting the body to temperatures as low as minus 256 degrees Fahrenheit (minus 160 Celsius). Cryotherapy aims to decrease pain and inflammation and aid healing.
Small problems, big solutions – Nanotechnology is a relatively new discipline that some scientists hope will have multiple applications to healthcare. Ray Kurzweil, an American futurist says that in his view by the 2020s, it may become possible to deploy tiny robots (or 'nanobots') through the body to overcome the problems of incorrect DNA replication -- one of the central causes of aging. In this photo, a student in the nanotechnology research and education center at the University of South Florida, looks through a microscope.
Hormone treatment – Early research into the effects of growth hormones on mice suggests various kinds of hormonal treatment may help to increase life expectancy. It is not yet known whether the results will be transferable to humans, but some hormone therapies have already made it to market.
Fresh-faced – According to a report by Global Industry Analysts the global anti-aging products market will be worth $291.9 billion by 2015. Every year in the U.S. alone, those fearing the inevitable signs of aging invest over $50 billion in skin care solutions. One of the more effective services is skin rejuvenation therapy or photorejuvenation in which a laser is used to induce controlled wounds on the skin, which then heals by creating new, wrinkle-free cells.
