On February 15, 2005 of the Physics/Einstein Year, the complete story of the discovery of natural atom antihydrogen, started in 1985, was published on-line.
The antihydrogen problem has become a highly mediatic issue, both in the specialized physics and the more general press . A real hype started at the end of 2002 when rivalling CERN-based groups ATHENA and ATRAP both claimed the production of large quantities of artificial antihydrogen. Scientists, wondering about a signature for the presence of this mysterious species antihydrogen, were disappointed as no direct signature whatever was presented. In fact, a spectral identification of antihydrogen is impossible since measuring its spectrum is exactly the goal of ATHENA and ATRAP collaborations.
Strangely, the same media failed to report that on October 21 2002, a paper was published with a signature for the antihydrogen atom in the observed line spectrum of natural H , an essential step in the discovery of natural antihydrogen by G. Van hooydonk, science professor at and former Chief-Librarian of the Ghent University. This signature would not make sense if it was not confirming an earlier signature in the band spectrum of natural molecular hydrogen . Both types of complementary signatures for natural antihydrogen, as well as a Mexican hat-type potential , were left unnoticed since the time of Bohr.

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...
