Study Finds Magnetic Therapy Really Works

Can placing magnets on your skin cure aches, pains, and sprains? So-called "magnetic therapy" is often considered to be a hoax under the guise of "alternative medicine." But now a study by biomedical engineering researchers at the University of Virginia has found that magnets may really provide biological healing. The scientific evidence for the controversial therapy may lead to mainstream use of magnets for athletes, the elderly, and others. read more »

Salt Energy Meets Solar Energy

Using molten salt to store solar energy, researchers hope to implement large-scale solar power generation, with a single tower capable of producing up to 500 megawatts of peak power. read more »

Swedish Building Heated With Body Heat

More than 250,000 people pass through the Stockholm Central Station every day. In the past, the body heat they release has posed problems, requiring open windows to air it out. But soon, the excess heat will be used to provide heating for a new office building nearby. read more »
