Squash preparation of stained onion root tip cells showing various stages of mitosis. Differential interference contrast optics on a Leica microscope, Image taken with the X40 objective lens.  Depth of focus is extremely shallow (just a few microns).  Differential interference contrast results in an optical slice horizontally through the specimen providing maximum possible resolution at this magnification and good contrast. Chromatic abberation is inevitable in light microscopy, but has been kept to a minimum in this image.
Monosodium glutamate, MSG or sodium glutamate molecules. MSG is used in cooking as a flavor enhancer with an umami taste 3d rendering
A ball and stick model of a Polytetrafluoroethylene molecule, also known as PTFE or most commonly Teflon. It is a polymer consisting of only carbon and fluorine atoms. It is used as a non-stick coating for cookware, as a lubricant, and it is also used to contain highly reactive chemicals as it is extremely non-reactive.
Biological protein and molecule, 3d rendering. 3D illustration.
Infection disease - 3d rendered image. Abstract pathogen scene. Microscopic view. Infection, disease microbiology concept. Fungal, mold, mushroom, spore, yeast, bacteria, yeast image.  SEM (TEM) view.
From left to right: the NMDA and  AMPA receptors transport calcium cations into neurons after being activated by the neurotransmitter glutamate and  the GABA receptor (right) transport chloride anions after the activation by gamma aminobutyrate. PDB entries: 6wht,  3kg2, 6d6u
Vegan burger ingredients isolated on a  table (bell pepper and peas)
The model shows the 30S ribosome RNA (blue), three tRNA (top), and ribosomal proteins. 3D Gaussian surface model, white background
This footage shows the translation initiation complex, which consists of the ribosomal small subunit, transfer RNA (tRNA), and translation initiation factors. The golden ribbon represents the RNA.
