The New York Times ran an obituary commemorating the life of Dr. Yvette Francis-McBarnette. I had never heard of her but found her life story inspirational, especially for budding minority scientists.

Dr Yvette Fay Francis-McBarnette

Yvette immigrated to New York City from Jamaica with her parents and at 14 years old she began studies at Hunter College. After completing a bachelor’s degree in physics, she began a master’s degree in chemistry at Columbia University. Then she went on to be come only the second black woman to earn a medical degree from Yale University.

As a physician, she made tremendous progress in studying and treating sickle cell anemia in young patients. Sickle cell disease deforms the shape of red blood cells, making them rigid and harder to pass through capillaries. It can lead to oxygen deprivation in organs and tissues and also severe pain. The disease is more prevalent in black and Mediterranean populations.Yvette pioneered new antibiotic treatments for the disease and established the Foundation for Research and Education in Sickle Cell Disease. And she did all of this work during the 1950s and 60s when women had fewer opportunities and less support than exists today, doubly so for black women.

 

2013 nobels

Nobel_medal

The 2013 Nobel prizes in medicine, physics, and chemistry were awarded this week, with the medals for literature, peace and economics are yet to come.

In medicine, James Rothman, Randy Schekman and Thomas Südhof received the prize for elucidating trafficking mechanisms within cells. Cells use vesicles (membrane enclosed bubbles) to transport different cargo between cellular compartments or to other cells. The three researchers won the award for discovering how these vesicles get directed to their intended target and how the cargo is eventually delivered. The Nobel summary can be found here.

In physics, the award goes to François Englert and Peter Higgs. Admittedly, I understand next to nothing about the Higgs boson, except that it is a subatomic particle that was confirmed to exist earlier this year. Particle physics is astonishing. You can read the summary here.

And in chemistry the prize goes to three scientists, Martin Karplus, Michael Levitt and Arieh Warshel. These three chemists, have developed computational models for complex chemical systems. The researchers are being recognized for basically pioneering this whole field. The computations are relevant to multiple areas of chemistry including protein folding, electron transfer and catalysis. The Nobel report is here.

Congratulations to the newly minted laureates.
