This deceptively simple image revolutionised molecular biology. It also represents one of the most notorious controversies in science. ‘Photo 51’ was taken by Rosalind Franklin, who was born on this day in 1920. It is an x-ray crystallography image of DNA, created by bombarding a tiny DNA sample with x-rays for more than 60 hours. To most of us, this striped cross might not mean much, but to a few scientists in 1953 it held the secret to the structure of DNA. The controversy surrounds the instant Maurice Wilkins, who worked in Franklin’s lab, showed the photo to Francis Crick, a molecular biologist at Cambridge University, without Franklin’s knowledge. Crick published a paper with his colleague James Watson describing DNA’s double-helix structure. Wilkins, Crick and Watson shared the Nobel Prize in 1962. Franklin, whose peers never accepted her, died of cancer four years earlier, and couldn’t receive the prize posthumously.

Chikungunya virus

betterknowamicrobe:

Let’s discuss another alphavirus, shall we? Chikungunya, or CHIKV, is a mosquito-borne pathogen on the move.

The virus is carried by Aedes mosquitoes, just like many other arboviruses. Arboviruses are arthropod-borne and include things like yellow fever, dengue fever, West Nile…

…Something to remember, or become aware of…
There are  greater than 200 known human viruses that have at one time or another been linked to patients with signs and symptoms that defined an ‘influenza-like illness.” (VDU’s blog)
