Overhead aerial drone view of oyster farm racks at low tide, flying at a low altitude to be able to see the detail of the oyster racks and seaweed. Located in a tidal estuary in Sutherland, Scotland. the low tides enable workers to access the racks for turning the oysters as they grow. Oysters have been farmed for many hundreds of years using this method. Seaweed has grown around the metal lines of racks.
Bacterial multidrug efflux pumps (E-CmeB) expel antibiotics  from inside the bacterium (bottom): ciprofloxacin (yellow), chloramphenicol (violet),  ampicillin (red).
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.

Glucose-6-phosphate dehydrogenase (G6PD) protein. Enzyme of the pentose phosphate pathway that generates co-enzyme NADPH. 3D illustration.
Endosomes - 3d rendered image of Endosomes are membrane-bound organelles. They are parts of endocytic membrane transport pathway.  Endomembrane system in cells. Bilayer Lipid Membrane. Abstract medical illustration. Microscopic view. Microbiologic research concept.
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.
