The importance of tobacco mosaic virus in the history of viruses cannot be overstated. It was the first virus to be discovered, and the first to be crystallised and its structure shown in detail. The first X-ray diffraction pictures of the crystallised virus were obtained by Bernal and Fankuchen in 1941.
The tobacco mosaic virus was the first to be crystallised and its structure could, therefore, be elucidated in detail. The first X-ray diffraction pictures of the crystallised virus were obtained by Bernal and Fankuchen in 1941. Based on her X-ray crystallographic pictures, Rosalind Franklin discovered the full structure of the virus in 1955. [21]
The viruses that cause epidemic jaundice were not discovered until the middle of the 20th century. [217] The names for epidemic jaundice, hepatitis A, and for blood-borne infectious jaundice, hepatitis B, were first used in 1947, [218] following a publication in 1946 giving evidence that the two diseases were distinct.

(In 1931, Beach had discovered the virus of infectious laryngotracheitis, now called Gallid alphaherpesvirus 1. [9]) They concluded that: It was found that chickens that recovered from an infection with one of the two strains of virus were refractory to further infection with either strain.
Marburg virus, first discovered in 1967, attracted widespread press attention in April 2005 for an outbreak in Angola. [131] Ebola virus disease has also caused intermittent outbreaks with high mortality rates since 1976 when it was first identified. The worst and most recent one is the 2013–2016 West Africa epidemic. [132]
The existence of the eerily-nicknamed viruses has been known to researchers for decades, but this is the first time traces of the viruses have been discovered in the US. Vampire viruses prey on ...
By the end of that decade, the miasma theory was struggling to compete with the germ theory of disease. Viruses were initially discovered in the 1890s. Eventually, a "golden era" of bacteriology ensued, during which the germ theory quickly led to the identification of the actual organisms that cause many diseases. [2]
The internet feels depressingly bleak these days: AI slop and bots are all over social media. We all exist in our own little online echo chambers.
