Main mutation site of the coronavirus variant B.1.531 emerged in South Africa. The spike protein (red) is bound to the angiotensin converting enzyme 2 (blue). The mutation is at the amino acid position 484 (yellow). Source: PDB entry 6cs2.
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.

Wet rough asphalt black bitumen road pavement surface abstract grunge texture close-up top view background banner.\nBitumen is a sticky, black, highly viscous liquid or semi-solid form of petroleum. In the U.S., it is commonly referred to as asphalt. It may be found in natural deposits or may be a refined product, and is classed as a pitch. Before the 20th century, the term asphaltum was also used.\nTarmacadam is a road surfacing material made by combining crushed stone, sand, and tar. It is a more durable and dust-free enhancement of simple compacted stone macadam surfaces. The terms \

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.
