Blood Pioneer

In 1947, Marie Maynard Daly – born on this day in 1921 – became the first African-American woman to receive a PhD in chemistry in the US. She was inspired by her mother’s passion for books and father’s love of chemistry. He immigrated to New York from the West Indies to become a chemist before Marie was born, but left university when money became tight. Marie completed what her father could not. She studied at Queens College and Columbia University, both in her home city of New York. Daly is particularly renowned for her research on the damaging potential of high blood pressure and fatty deposits inside blood vessels, work which led to a better understanding of the cause of heart attacks. Alongside her research, Daly developed opportunities for students from minority backgrounds. She established a scholarship fund for minority African-American science students in honour of her father.

Neurons growing in a cell culture

These time lapse animations use phase contrast microscopy to show neural stem cells in a nutrient medium for 4 hours.  They reveal the dynamic growth and recycling of dendrites and synapses as neurons establish relationships with each other.  The social behavior of these cells creates the incredible properties of the mind and brain.
