Where health and energy conservation meet: Hong Kong’s California Fitness.

A health club here is hoping that a car battery, some StairMasters and dozens of gym rats can help ease the world’s energy problems.

Rita Wong is doing her part. One evening recently, the fit 27-year-old, dressed in black spandex, pedaled furiously on an elliptical machine at the California Fitness health club. As she worked up a sweat to a Madonna song blasting on the gym’s sound system, the energy she created was transformed into electricity and stored in a battery that powers some of the gym’s lights.

While we foolishly debate whether we should even research stem cells the Japanese are already using stem cells in cosmetic surgeries.

Women have grown their own breast implants through pioneering stem cell treatment, it emerged yesterday.

Scientists harvested the stem cells from the women’s own fat and encouraged them to form breast tissue.

The technique creates more natural looking breasts that don’t shrink over time and don’t have problems with leaky implants.
