Today’s STEM Girl is Esther Lederberg.  She was the first to solve the problem of reproducing bacterial colonies en masse with the same original geometry using a technique known as replica plating.  Her method was simple, using only a specific type of velvet.  Much of the credit for her discoveries went to her husband, Joshue.

The man who discovered Pluto is currently on his way there! Or at least his ashes are... Clyde Tombaugh discovered Pluto in February, 1930. He died at the age of 90 in 1997 and his ashes were placed inside a capsule inscribed with the writing that would normally go on one's gravestone. That capsule is currently on board the New Horizons space probe, which should pass Pluto in 2015.

Chien-Shiung Wu (1912-1997) was a Chinese-American scientist who made important contributions to the field of nuclear physics. She is best known for conducting the Wu experiment, and for separating uranium metal into isotopes. These achievements led to her two male colleagues winning the Nobel Prize in Physics in 1957.

How can we support Sarah? Sarah Robles is the strongest woman in America. She’s beaten every other competitor, male and female, to become the highest-ranked lifter in the USA. She’s an Olympian at 23. She could lift your entire nuclear family and throw them, and she lives on 400 bucks a month because for some mysterious reason she can’t get endorsement deals.

Dorothy Crowfoot Hodgkin (1910-1994) was a founder of protein crystallography.    Hodgkin and her mentor, J.D. Bernal, were the first to successfully apply X-ray diffraction to biological crystals. She identified the structures of cholesterol, lactoglobulin, ferritin, tobacco mosaic virus, penicillin, and vitamin B-12. She also described the structure of insulin in 1969, a problem on which she worked for 34 years.
