New discovery at Jupiter could help protect Earth-orbit satellites
Radio waves accelerate electrons within Jupiter's magnetic field in the same way as they do on Earth, according to new research published in Nature Physics this week. The discovery overturns a theory that has held sway for more than a generation and has important implications for protecting Earth-orbiting satellites. view more (2008-03-10)
Mechanism Behind Stuttering Revealed (p 380)
Stuttering is caused by a structural abnormality in the left hemisphere of the brain, according to an article in this week's LANCET. Dr Martin Sommer and colleagues from the Universities of Hamburg and Göttingen in Germany report that persistent developmental stuttering results from a disconnection of speech-related areas in the cortex.... view more...

Are tumors causing stricture of bile duct always malignant?
The benign biliary tract tumor is rarely found in clinical practice. One case of bile duct adenomyoma was recently reported in the January 28 issue of the World Journal of Gastroenterology. view more (2008-02-22)
Delft University of Technology rotates electron spin with electric field
Researchers at the Delft University of Technology's Kavli Institute of Nanoscience and the Foundation for Fundamental Research on Matter (FOM) have succeeded in controlling the spin of a single electron merely by using electric fields. view more (2007-11-02)
Magnetism shapes beauty in the heavens
Using a technique based on the work of the 1902 Nobel Prizewinner, Pieter Zeeman, an international team of astronomers have, for the first time, provided conclusive proof that the magnetic field close to a number of aging stars is 10 to 100 times stronger than that of our own Sun. These observations suggest a solution to the long outstanding... view more... (2002-11-01)
Penn research shows transcranial magnetic stimulation effective in treating major depression
Researchers at the University of Pennsylvania School of Medicine and other study sites have found that transcranial magnetic stimulation (TMS) - a non-invasive technique that excites neurons in the brain via magnetic pulses passed through the scalp - is a safe and effective, non-drug treatment with minimal side effects for patients with major... view more...

Scientists get new facility to study materials
A new scientific research instrument on the Isis Facility at the CLRC Rutherford Appleton Laboratory was officially inaugurated today, Friday 6 October. The Osiris spectrometer will provide scientists with the unrivalled combination of a spectrometer and a diffractometer in the same instrument. Using this they will be able to measure where the... view more... (2000-10-06)
Neurobiology of dread gives scientists clues about human decision making
In order to better understand how people make decisions when the outcomes are known to be unpleasant, a team of Emory neuroscientists led by Gregory Berns, MD, PhD, used functional magnetic resonance imaging (fMRI) to determine the areas of the brain that are activated when someone experiences dread. view more (2006-05-05)
Noninvasive Screening Test May Detect Narrowing in Intracranial Stents According to Study by Rush University Medical Center
Great advances have been made in treating blockages in the arteries of the brain using angioplasty to widen the narrowed artery and a stent to hold the artery open. view more (2009-02-12)
Scientists Discover Magnetic Superatoms
A team of Virginia Commonwealth University scientists has discovered a 'magnetic superatom' - a stable cluster of atoms that can mimic different elements of the periodic table - that one day may be used to create molecular electronic devices for the next generation of faster computers with larger memory storage. view more (2009-06-16)
Chronic drinking and smoking cause both separate and interactive brain injury
Most alcoholics in North America are chronic smokers. While much is known about the adverse effects of chronic smoking on cardiac, pulmonary and vascular function as well as the risk for various cancers, little is known about its effects on brain neurobiology and function. view more (2006-01-25)
Giant eruption reveals 'dead' star
An enormous eruption has found its way to Earth after travelling for many thousands of years across space. Studying this blast with ESA's XMM-Newton and Integral space observatories, astronomers have discovered a dead star belonging to a rare group: the magnetars. view more (2009-06-17)
Trial raises doubts over alternative pain therapy for arthritis
Copper bracelets and magnetic wrist straps are ineffective in relieving arthritis pain, according to a new study led by a University of York academic. view more (2009-10-16)
Neurological differences support dyslexia subtypes
Parts of the right hemisphere of the brains of people with dyslexia have been shown to differ from those of normal readers. view more (2009-06-25)
Newborn brains grow vision and movement regions first
The regions of the brain that control vision and other sensory information grow dramatically in the first few months following birth, while the area that controls abstract thought experiences very little growth during the same period, University of North Carolina at Chapel Hill researchers have found. view more (2007-02-09)
New Graphene-Based Material Clarifies Graphite Oxide Chemistry
A new "graphene-based" material that helps solve the structure of graphite oxide and could lead to other potential discoveries of the one-atom thick substance called graphene, which has applications in nanoelectronics, energy storage and production, and transportation such as airplanes and cars, has been created by researchers at The... view more...

University of Miami physicist develops battery using new source of energy
Researchers at the University of Miami and at the Universities of Tokyo and Tohoku, Japan, have been able to prove the existence of a "spin battery," a battery that is "charged" by applying a large magnetic field to nano-magnets in a device called a magnetic tunnel junction (MTJ). view more (2009-03-12)
Mate or hibernate? That's the question worm pheromones answer
If worms could talk, they might tell potential suitors, "I like the way you wriggle," complete with that telltale come slither look. view more (2008-07-25)
Microwires: replacement for the CD-ROM?
A ballpoint that detects if we are forging a signature or a substitute in miniature for the CD-ROM are some of the applications that can be carried out using microwires. view more (2005-03-07)
Morning people and night owls show different brain function: University of Alberta study
Are you a "morning person" or a "night owl?" Scientists at the University of Alberta have found that there are significant differences in the way our brains function depending on whether we're early risers or night owls. view more (2009-06-24)
