Dimitri Mendeleev, a Russian, and Lothar Meyer, a German, published early versions of periodic tables in 1869 and 1870, respectively. Well, roll over, Mendeleev, tell Meyer the news: Washington Universitys Katharina Lodders has developed an innovative periodic table, slanted toward astronomy, thats definitely not your fathers periodic table.

Revised periodic table slanted toward astronomers
The periodic table isn’t what it used to be, thanks to innovations by a planetary chemist at Washington University in St. Louis.
Katharina Lodders, Ph.D., Washington University research associate professor in Earth and Planetary Sciences in Arts & Sciences, has evalutated data from numerous studies including her own and arranged the data into a periodic table slanted toward astronomers and cosmochemists. It’s the Cosmochemical Periodic Table of the Elements in the Solar System. Instead of atomic number, atomic weights, and melting- and boiling points, for example, Lodders provides elemental abundances and condensation temperatures. And it’s color-coded to indicate host phases of the elements - the phase where the element condenses into metal, sulfide, or silicate rock.

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...
