Frederick William Twort FRS [1] (22 October 1877 – 20 March 1950) was an English bacteriologist and was the original discoverer in 1915 of bacteriophages (viruses that infect bacteria). [4] He studied medicine at St Thomas's Hospital , London , was superintendent of the Brown Institute for Animals (a pathology research centre), and was a ...
The Vine–Matthews–Morley hypothesis, also known as the Morley–Vine–Matthews hypothesis, was the first key scientific test of the seafloor spreading theory of continental drift and plate tectonics. Its key impact was that it allowed the rates of plate motions at mid-ocean ridges to be computed.
1963: In a major advance in the development of plate tectonics theory, the Vine–Matthews–Morley hypothesis was independently proposed by Lawrence Morley, and by Fred Vine and Drummond Matthews, linking seafloor spreading and the symmetric "zebra pattern" of magnetic reversals in the basalt rocks on either side of mid-ocean ridges.

Pelagibacter ubique, the most abundant bacteria in the ocean, plays a major role in the global carbon cycle. Vibrio vulnificus, a virulent bacterium found in estuaries and along coastal areas Electron micrograph showing a species of the widespread cyanobacteria Synechococcus. Carboxysomes appear as polyhedral dark structures.
Martinus Beijerinck called the filtered, infectious substance a "virus" and this discovery is considered to be the beginning of virology. The subsequent discovery and partial characterization of bacteriophages by Frederick Twort and Félix d'Herelle further
The bacteria are found naturally in warm seawater, and can cause a severe and potentially life-threatening illness in humans called vibriosis. Some experts warn it could pose a growing threat.
These bacteria are commonly found in iron and manganese deposits on surfaces exposed intermittently to plumes of hydrothermal and bottom seawater. However, due to the rapid oxidation of Fe 2+ in neutral and alkaline waters (i.e. freshwater and seawater), bacteria responsible for the oxidative deposition of iron would be more commonly found in ...
A type of bacteria that causes dental plaque may be behind a treatment-resistant form of colorectal cancer, a study published Wednesday in the journal Nature found.. The particular bacterium ...
