3D cartoon and Gaussian surface models, PDB 2vtb, white background.

Cells in the body examined by endoscope

Bacterial multidrug efflux pumps (E-CmeB) expel antibiotics from inside the bacterium (bottom): ciprofloxacin (yellow), chloramphenicol (violet), ampicillin (red).

Micrograph of amoeba. Live specimen. Wet mount, 40X objective, transmitted brightfield illumination. Note - motion blur of live animal, very shallow depth of field, chromatic aberration and uneven focus are inherent in light microscopy.

Microscopic photo of a thin section of calcareous tufa of Holocene age.

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.

Dna structure digital concept

3D cartoon and Gaussian surface models, chain id color scheme, PDB 2y73, white background

Quantum Gravity 3d rendered image of a comprehensive exploration of Quantum Gravity theories. String theory, loop quantum gravity (LOG), causal dynamical triangulation, twistor theory, gravitational waves, spacetime, gravity waves, quantum mechanics, quantum entanglement concepts.

After dopamine binding, the dopamine receptor changes his shape and binds the inactive G protein.The G protein expels its GDP molecule replacing it by GTP. and falls into two pieces. The Galpha subunit binds to and activates the enzyme adenylyl cyclase, which produces then cyclic AMP spreading a signal through the cell.

Artificial Intelligence Sustainable Responsible Technology

Colorful, abstract micrograph of a fish scale, calico bass,Paralabrax clathratus, with polarization at 100x.

Green illuminate glitter bokeh for background for concept and more idea for creative

Calcidiol molecule, also called calcifediol, major circulating metabolite of vitamin D3 produced in liver, 3D illustration

Conceptual image of a polluted environment with plenty of plastic bottles, bags, microspheres and generic waste floating in blue water. Abstract plastic pollution background. Digitally generated image.

B-chain pentamer and A-chain subunit (green), 3D cartoon and Gaussian surface model, white background

DNA Helix - 3d rendered image. Genetic research concept. Complex spiral structure illustration. Medical, science, genetic biotechnology, gene cell, chromosome idea. DNA strands on dark background . Science nanotechnology.

3d rendered Gastric inhibitory polypeptide (GIP, glucose-dependent insulinotropic peptide) endocrine protein hormone, 3D illustration

Photomicrograph of flatworm,

Haematococcus pluvialis green and cyst algae under microscopic view, empty space - haematocyst, active and resting cells, strong antioxidant astaxanthin

A ball-and-stick plus ribbons molecular model of the hormone Orexin, also known as Hypocretin. Orexin is involved in the regulation of the sleep/wake cycle and it stimulates apetite, wakefulness and energy expenditure. It has been linked with Alzheimer's disease. Isolated on white.

Hyaluronan, hyaluronic acid, HA, hyaluronate molecule, short fragment. Molecular model. 3D rendering. Illustration

A conceptual image of an abstract network of multi-coloured organic strands arranged in a non regular pattern all connected together in a complex manner. The network is made from smaller multi-coloured squares and polyhedra, in vivid colours against a pastel toned background. Shows background and foreground elements to the structure.

3D cartoon and Gaussian surface models, PDB 2gjx, white background

Firing Neurons Hologram - 3d rendered image of Neuron cell network on black background. Conceptual medical illustration. Healthcare concept. SEM [TEM] view. Glowing neurons signals.

p53 (blue) tagged with ubiquitin (yellow) is degraded into small peptides by a proteasome (violett). p53 prevents cancer formation and acts as a guardian of the genome. Mutations in the p53 gene contribute to about half of the cases of human cancer.

Fatty liver disease (steatosis) is a common condition caused by having too much fat build up in your liver. A healthy liver contains a small amount of fat. It becomes a problem when fat reaches 5% to 10% of your liver's weight.
