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.

Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.
Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....
Physicists from the University of Würzburg are capable of generating identical looking single light particles at the push of a button. Two new studies now demonstrate the potential this method holds.
The quantum computer has fuelled the imagination of scientists for decades: It is based on fundamentally different phenomena than a conventional computer....
An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.
We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...
Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.
Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...
