Other groups of physicists such as theAlpha Collaborationat CERN are working at much lower energies to see if the properties of antimatter really are the mirror of their matter partners. Theirlatest resultsshow that an anti-hydrogen atom (made up of an anti-proton and an anti-electron, or po...
Theantiprotonwas discovered in 1955. Unlike a proton (which has a charge of +1), an antiproton has a charge of -1. It is different from an electron because although an electron also has a charge of -1, electrons have a tiny relative mass whereas antiprotons have a relative mass of ...
An proton-antiproton pair is produced by a 2.00 x 10^3 MeV photon. What is the kinetic energy of the antiproton if the kinetic energy of the proton is 82.53 MeV? if an electron and a proton (both initially at rest and far apart) come to...

Electron micrographs were analyzed blinded, where endosomes and endoplasmic reticulum were separately identified and labeled using Fiji Software (ImageJ, NIH). The percentage of endosomes with an ER contact site were quantified as described previously...
AioE belongs to TrkA family corresponding the electron transport function with the generation of NADH and H+. An aioE in-frame deletion strain showed a null AsIII oxidation and a reduced AsIII resistance, while a cytC mutant only reduced AsIII oxidation efficiency. With AsIII, aioE was ...
Cells were grown at 37 °C in a Varioskan Flash (Thermo 399 Electron Corporation) luminometer and relative luminescence units (RLU) and OD492 values were recorded throughout incubation. To calculate the XA and XB values, the theoretical regression of each slope before and during the first ...
