Researchers from Mayo Clinic in Jacksonville, Fla., report wearing ionized bracelets for the treatment of muscle and joint pain was no more effective than wearing placebo bracelets in the November 2002 issue of Mayo Clinic Proceedings.

Authors of the published study randomly assigned 305 participants to wear an ionized bracelet for 28 days and another 305 participants to wear a placebo bracelet for the same duration.

The study volunteers were men and women 18 and older who had sel

A new optical antenna, developed by researchers at the University of Warwick, will bring significant benefits to credit card payments, wireless networks, household electronics and longer distance data transfer.

The device was developed by Professor Roger Green and Roberto Ramirez-Iniguez, in the University of Warwick`s Engineering Department. It applies techniques used to manipulate radio frequencies to select the incoming “signal frequencies” carried on infrared beams to produce the optica

The “island effect” is one of the main problems in photovoltaic compound solar systems.

The doctoral thesis of Pablo Sanchis, presented in the Public University of Navarre (Basque Country), proposes three main contributions: the first one is a new control strategy of a booster inverter for autonomous systems; the second one is a new implementation of impedance measurement method, and the third one, a new methodology for the design of drift method in frequency, which guarantees with t

A special place on the market of food supplements belongs to ecdysteroid-containing preparations that are helpful as a tonic for sportsmen during intensive training sessions, for people of various professions connected with physical and psychological stresses, and also for elderly people. Ecdysteroids heal wounds and burns.

A plant containing very high concentrations of ecdysteroids has been found by a team headed by Vladimir Volodin from the Institute of Biology in Syktyvkar. This is saw-w

An international team of astronomers, led by scientists at the University of Manchester have produced new evidence that most of the energy in the Universe is in the form of the mysterious “Dark Energy”. The new evidence comes from a 10-year census of the sky for examples of gravitational lenses, which are seen when a galaxy bends the light from a distant quasar to form several images of the same quasar. Linking the number of lenses they found with the latest information on the numbers of galaxies, th

A diet rich in flaxseed seems to reduce the size, aggressiveness and severity of tumors in mice that have been genetically engineered to develop prostate cancer, according to new research from Duke University Medical Center. And in 3 percent of the mice, the flaxseed diet kept them from getting the disease at all.

“We are cautiously optimistic about these findings,” said Wendy Demark-Wahnefried, Ph.D., associate professor, division of urology and senior author of the study that appears in t
