Observations of explosions from an ultra-powerful magnetic neutron star playing hide-and-seek with astronomers suggest that these exotic objects called magnetars — capable of stripping a credit card clean 100,000 miles away — are far more common than previously thought.
Scientists from the United States and Canada present this result today at the meeting of the American Astronomical Society in Atlanta . The work is based on observations with the European Space Agencys XMM-Newton observatory and NASAs Rossi X-ray Timing Explorer.
"We only know of about ten magnetars in the Milky Way galaxy," said the investigations leader, Dr. Peter Woods of NASAs Marshall Space Flight Center in Huntsville , Ala. , based at the National Space Science and Technology in Huntsville . "If the antics of the magnetar we are studying now are typical, turning on and off but never getting exceptionally bright, then there very well could be hundreds more out there."

New proton record: Researchers measure magnetic moment with greatest possible precision

High-precision measurement of the g-factor eleven times more precise than before / Results indicate a strong similarity between protons and antiprotons
The magnetic moment of an individual proton is inconceivably small, but can still be quantified. The basis for undertaking this measurement was laid over ten...

The WHO reports an estimated 429,000 malaria deaths each year. The disease mostly affects tropical and subtropical regions and in particular the African continent. The Fraunhofer Institute for Silicate Research ISC teamed up with the Fraunhofer Institute for Molecular Biology and Applied Ecology IME and the Institute of Tropical Medicine at the University of Tübingen for a new test method to detect malaria parasites in blood. The idea of the research project “NanoFRET” is to develop a highly sensitive and reliable rapid diagnostic test so that patient treatment can begin as early as possible.
Malaria is caused by parasites transmitted by mosquito bite. The most dangerous form of malaria is malaria tropica. Left untreated, it is fatal in most cases....
The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.
Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...
Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.
That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...
