electrons. the number of electrons is equal to the number of protons thus resulting in a neutral atom of an element. the electronic arrangements determine the chemical properties of an element whereas the nuclear structure dictates the stability and radioactive transformation of the atom. fundamental...
Timeline: The Discovery Of Elements, Chemical Element TIMELINE: The Discovery of Elements Early history The elements carbon, sulfur, iron, tin, lead, copper, mercury, silver, and gold are known to humans. Pre-a.d. 1600: The elements arsenic, antimony, bismuth, and zinc are known to human...
Allure and romance are rarely expected in an article presented under the bulky headline “Criteria that must be satisfied for the discovery of a new chemical element to be recognized.” However, the members of the Transfermium Working Group (TWG) worked out a most fascinating publication on a ...
Factor analysis decomposes single-cell gene expression data into a minimal set of gene programs that correspond to processes executed by cells in a sample. However, matrix factorization methods are prone to technical artifacts and poor factor interpretability. We address these concerns with Spectra, an...

Osteoarthritis causes debilitating pain and disability, resulting in a considerable socioeconomic burden, yet no drugs are available that prevent disease onset or progression. Here, we develop, validate and use rapid-throughput imaging techniques to iden
The current number of gene calls for Pgt is 20,567, 18,241 when disregarding many transposable element- (TE) related calls, and will likely be similar for Pt (and Pst). We have only compared a partial Pt gene set, based on the EST unigenes, but, assuming we can extrapolate the ...
Metals are classified into two categories based on the presence of other elements: pure metal and alloy. Pure metal is made up of only one element: the pure element. The metal kinds listed in the previous category are all pure metals based on the periodic table. In contrast, an alloy ...
These results are consistent with the models for IS605 TnpB function proposed by the Siksnys lab23 and experimentally confirmed by the Sternberg lab,68 indicating the putative function of IS607 TnpB in the life cycle of the mobile element. Methods Plasmid construction Genes encoding IS607 TnpB...
