Unexplained and severe tinnitus–a ringing or buzzing in the ears–can be temporarily reduced in some patients by “jamming” the brains electrical activity with focused magnetic stimulation, according to a preliminary study to be published December 23, 2002 in the online edition of the Annals of Neurology. The results confirm that some phantom sounds are generated by abnormal activity in the brain itself.
“Controlled clinical trials are now necessary to evaluate whether this method can
Don’t worry – you are not the only one who thought this was a nice amateur photo of planet Saturn, Lord of the Rings in our Solar System!
But then the relative brightness and positions of the moons may appear somewhat unfamiliar… and the ring system does look unusually bright when compared to the planetary disk…??
Well, it is not Saturn, but Uranus, the next giant planet further out, located at a distance of about 3,000 million km, or 20 times the distance between the Sun and t
Life expectancy and prosperity will continue to rise and food production should keep up with population growth, but the Kyoto agreement will have little effect on global warming according to this week’s Christmas issue of the BMJ.
Using official statistics and global trends, Bjørn Lomborg, Director of the Danish Environmental Assessment Institute and author of The Skeptical Environmentalist attempts to draw a reasonably good picture of the true state of the world.
Life expectancy fo
Research continues in an effort to determine if these neural cells can be transplanted to treat stroke, brain tumors and neurodegenerative disorders
Researchers at Cedars-Sinais Maxine Dunitz Neurosurgical Institute have for the first time demonstrated that stem cells from whole adult bone marrow can be differentiated into several types of cells of the central nervous system.
A long-term objective of this research is to determine if these neural stem cells can be trans
The Zeolite Crystal Growth (ZCG) experiment got off to a successful start this week aboard the International Space Station.
Hard as a rock, yet able to absorb liquids and gases like a sponge, zeolites form the backbone of the chemical processes industry. Virtually all the world’s gasoline is produced or upgraded using zeolites. Improving zeolites could make gasoline production more efficient or lead to ways of storing clean-burning hydrogen for fuel. Zeolites can also be applied to
Researchers at Washington University School of Medicine in St. Louis have discovered a possible new mechanism for regulating large groups of genes. While conducting yeast research on a potential new anticancer drug, the team identified a mechanism that enables the genome to silence large numbers of genes simultaneously, rather than each gene individually.
The finding emerged during research studying the molecular action of the drug rapamycin. Rapamycin currently is used to suppress the immu
