How Rosalind Franklin’s story was rewritten

In this episode:

00:57 Franklin’s real role

When it comes to the structure of DNA, everyone thinks they know Rosalind Franklin’s role in its discovery. The story goes that her crucial data was taken by James Watson without her knowledge, helping him and Francis Crick solve the structure. However, new evidence has revealed that this wasn’t really the case. Rosalind Franklin was not a ‘wronged heroine’, she was an equal contributor to the discovery.

16:06 Why multisensory experiences can make stronger memories

It’s recognized that multisensory experiences can create strong memories and that later-on, a single sensory experience can trigger memories of the whole event, like a specific smell conjuring a visual memory. But the neural mechanisms behind this are not well understood. Now, a team has shown that rich sensory experiences can create a direct neural circuit between the memory regions of fruit fly brains. This circuit increases memory strength in the flies, and helps explain how sense and memories are interlinked.
