Thematic examination of how the Soviet Union changed from 1957 to 1968. Some chapters were on topics I knew well - like the space program and dissidents - but others - like the changes in housing and consumer goods were completely new. Enjoyed very much.

I’m sorry but there is still something to be learned in the stacks of a physical library.

I keep reposting myself - but #teammassspec doing #metabolomics - we would love for you to use your MS2 data to try out our identification model - which in our hands gives greater a higher number secure than other AI models and cosine similarity.

At Matterworks have introduced a new model for metabolomics MS2 identification which is has open early access. In our hands it outperforms existing AI and traditional techniques. We would love your feedback.

Congratulations to Devesh Shah and Gabriel Asher - two of my amazing ML colleagues @matterworks.bsky.social for their preprint on foundation models for both MS2 identification and rapid phenotype separation without feature annotation.
LSM-MS2: A Foundation Model Bridging Spectral Identification and Biological Interpretation
A vast majority of mass spectrometry data remains uncharacterized, leaving much of its biological and chemical information untapped. Recent advances in machine learning have begun to address this gap,...

My mother’s hero. The massive Tommy Douglas portrait in Leon’s office in Street Legal was a great touch of left wing Canadiana.
On this day in 1904, Tommy Douglas was born. From 1944 to 1961, he was the Premier of Saskatchewan. Among his accomplishments was creating North America's first single-payer universal healthcare program.
He led the federal NDP from 1961 to 1971.

Before they led their country’s revolutions, Lenin, Mao and Castro completed arduous journeys which ended their meeting American journalists who told, and perhaps romanticized, their story. Interesting use of the shared theme, and focusing on the journalists more than the revolutionaries.

#NoKings Boston featured endless people. A wide variety of ages, many families, and home made signs galore. Sheila Divine and Ayanna Pressley were highlights. Happy to hear Ed Markey and Elizabeth Warren speak.

Today is Persons Day.
This day honours The Persons Case, which ended in a victory for The Famous Five on Oct. 18, 1929. The ruling declared women to be persons under the law and qualified to sit in the Senate.
This is the story of that case.

Maud Menten was born in Canada in 1879 and completed her UG and MD education at University of Toronto. As a research assistant with Leonor Michaelis in 1912, they wrote the classic paper describing the “Michaelis-Menten” model of enzyme kinetics.. #WomenInScience

In 1990 I visited Zagreb, Yugoslavia - and both places are minor character in this wonderful novel - a single chapter of stream of consciousness written to unmet character - architecture, family, the fidelity of childhood memories - all make an appearance.
