The IUPAC/IUPAP Joint Working Party (JWP) on the priority of claims to the discovery of new elements has reviewed the relevant literature pertaining to several claims. In accordance with the criteria for the discovery of elements previously established by the 1992 IUPAC/IUPAP Transfermium Working Group (TWG), and reiterated by the 1999 and 2003 IUPAC/IUPAP JWPs, it was determined that the 1996 and 2002 claims by the Hofmann et al. research collaborations for the discovery of the element with…

Procedures for the Naming of a New Element
TLDR
The naming of new elements is carried out by IUPAC alone, which utilises its standard procedures for the recommendation of a suitable name and is then approved by the Council before being formally announced.
Chemistry of superheavy elements
Abstract The chemistry of superheavy elements - or transactinides from their position in the Periodic Table - is summarized. After giving an overview over historical developments, nuclear aspects…
Reexamination of the Claim of Marinov et al. on Discovery of Element 112
Marinov et al. have detected spontaneous fission events in sources separated from tungsten targets irradiated with 24 GeV protons. These fission events could not be attributed to actinides or to any…
Production and Identification of Transactinide Elements
Microscopic nuclear theories predict a region of superheavy elements (SHEs) at the next doubly magic shell closure above 208Pb. Early models locate the shell closure at Z = 114,more recent…

Comments on the question of the discovery of element 112 as early as 1971
Abstract There are two independent claims for the discovery of element 112: The claim by Hofmann et al. from 1996 and the older claim from 1971 by Marinov et al. This Comment will not challenge the…
The chemical separation of Eka-Hg from CERN W targets in view of recent relativistic calculations
Abstract In 1971 evidence for the production of element 112 via secondary reactions in CERN W targets was obtained. The evidence was mainly based on the observation of fission fragments in Hg sources…

Formation of spin-one mesons by photon-photon fusion.
TLDR
Whether the X(1420) could be the partner of the f/sub 1/(1285) in the J/sup P//sup C/ = 1/sup ++/ meson nonet is considered, and the width of each resonance was determined in several Q/sup 2/ bins.
Interactions of relativistic heavy ions in thick heavy element targets and some unresolved problems
Interactions of relativistic heavy ions with total energies above 30 GeV in thick Cu and Pb targets (≥ 2 cm) have been studied with various techniques. Radiochemical irradiation experiments using…
Tests of quantum electrodynamics with two-, three-, and four-photon final states from e+e- annihilation at sqrt s =29 GeV.
TLDR
High-precision measurements of electron-positron annihilation into final states of two, three, and four photons are presented and two events from the reaction e/sup +/e/sup -/..--> gamma Gamma gamma gamma gamma.. are found, in agreement with the QED prediction.

TLDR
I am writing with a simple plea to balance the voluminous articles about treatment in your journal with a modicum of information about nature and caring effects to rekindle the perception of physicians as healers, not only treaters, who relish the gifts of nature, and foster the humanistic aspect of medicine that has thrived for millennia.
