An excellent lecture in an “Explain-Like-I’m-Five” format by Anna Urum about CRISPR/CAS and genome editing. Anna is a student at the Department of Genetics at the Faculty of Biology of Moscow State University, and a staff member of the Cell Biology Laboratory at the Russian Federal Research Clinical Center of Federal Medical-Biological Agency, and despite her limited experience, she is very commendable

Today I am presenting in Kyiv (remotely).

I was there exactly six years ago, on March 25, 2013. It snowed. There was an emergency. I didn’t get to see the city because there was no means of transportation – everything was out of order 🙂 APCs helped trolleys not to slide down the hill backwards and block the passage for the few SUVs. The ‘U’ in a triangle on the APC was amusing in itself)

An intriguing little life hack for calculating percentages:

X% of Y = Y% of X

So, for example, if you need to calculate 4% of 75 mentally, just swap the numbers and calculate 75% of 4, which is much easier.

Understandably, this is somewhat obvious from a mathematical point of view (100 in the denominator moves to the second factor), but nobody has been doing this in mental calculations, right?
