Requiescat in pace...

[Weizmann Institute @WeizmannScience]

We, the Weizmann Institute of Science community, deeply mourn the passing of Prof. Ada Yonath of the Institute’s Chemical and Structural Biology Department. Prof. Yonath pioneered the study of the ribosome, the cell’s protein factory, and was awarded the 2009 Nobel Prize in Chemistry for her research in this field. Her decades-long scientific journey led to an understanding of how various antibiotics work, helping pave the way for the development of new antibiotics and the fight against antibiotic-resistant bacteria.
Yonath, the first Israeli woman scientist to win a Nobel Prize, also received dozens of other awards and honors, including the Israel Prize in Chemistry and the Wolf Prize in Chemistry. Prof. Yonath exemplified how scientific vision, the courage to choose a major scientific question and unwavering dedication to its pursuit can lead to extraordinary achievements and expand the boundaries of knowledge for the future of humanity.
May her memory be a blessing.

[RNA @RNAJournal]

Loss of a base (A3027) in the sarcin/ricin loop (PDB 4V7R) of 25S rRNA is sensed by factors detecting slow-moving ribosomes. Ubiquitination of the small subunit occurs, despite large subunit damage. https://t.co/GOHSjaRmq1

"La ignorancia engendra confianza con más frecuencia que el conocimiento: son los que saben poco, no los que saben mucho, los que afirman tan positivamente que tal o cual problema nunca será resuelto por la ciencia."

Stephen Hawking was born on the 300th anniversary of Galileo Galilei and died 7 years ago Today, at the age of 76, on the birthday of Albert Einstein and π day.

Did you know?

NASA only uses 15 digits of π for calculating interplanetary travel.

At 40 digits, you could calculate the circumference of a circle the size of the visible universe with an accuracy that'd fall off by less than the diameter of a hydrogen atom.

One of the most iconic #PDB50structures is the ribosome, the molecular machine responsible for protein production, which earned Ramakrishnan, Steitz and Yonath the 2009 Nobel Prize in Chemistry. View the bacterial ribosome: https://t.co/doD6rekMRq

Hans Krebs identified the citric acid cycle - also known as the Krebs cycle. The cycle is a series of reactions that convert nutrients into other molecules with a large amount of chemical energy.

Do you know why it is so important?
