Since there’s an opening for press secretary, I know a great candidate who’s not only a lawyer, but a neurosurgeon, a Grammy-winning recording artist, and the inventor of the Post-It Note.

I would be overjoyed if our politicians stopped at this level of shame 😊
Alom Shaha@alomshaha.bsky.social · last mo.See, I have confused some of you. Sadly, I will not be presenting the Christmas Lectures, that job goes to proper scientist Jim Al-Khalili who has just written a book for adults on the science of Time. I’m just shamelessly trying to use this as a way to promote my book for children.
A despised President is trying to tear down a monument erected by a grateful nation to honor a beloved, fallen, hero who not only served in the military, but also as President, forcing Russia to back away from Cuba, and beginning the mission to land on the moon. The contrast couldn't be sharper.

On 9/11, flying to the U.S. from Europe, we landed in Halifax and were taken to a red cross shelter. Next couple of days, Canadians were lined up at the shelter begging us to spend the night in their homes. School kids sent hand drawn sympathy cards. Truly, the kindest of people!

I’ve been to Jew-town in Kochi, and it’s one of the most beautiful things I experienced. A feeling of many bodies one soul - the India of old.

Kinetic and diffusion asymmetry combine with dissipation to provide the time and space symmetry breaking to give rise to directional motion for nanoscale enzymes. This mechanism enables the generation of higher-order tensorial outputs from scalar energy input. onlinelibrary.wiley.com/doi/10.1002/...
Molecular Active Matter, Kinetic Asymmetry, and Non‐Reciprocal Interactions
Nanoscale enzymes constitute dissipative active matter that converts scalar energy input into vectorial outputs. Through kinetic and diffusion asymmetry, they break time and space symmetry, resulting....

This was written by Henry Scott Holland (27 January 1847 – 17 March 1918). He was Regius Professor of Divinity at the University of Oxford. The poem is actually not a poem at all but rather part of a larger speech Henry Scott Holland gave. .
Welcome to the Fascist States of America, where the EiC of a leading journal is forcibly removed by police for passing out his own editorial at the annual meeting of the field’s association…because it’s “too political” (read: it calls on scientists to speak out & stand up). We are here. This is it.
We entered it last year my friends. We are now neck deep in it.

The interaction of ions or small molecules with proteins causes convective flows due to the displacement of water from the hydration shell. As shown, the replacement of the nickel ion removed from ur...
