I'm playing my part to support #biomanufacturing #biofabrication #biofoundry(ies) and bear witness to the birth of an industry. Working with 2 novel compounds to grow bone, cartilage & other types of cells. Turns out they also work for growing hearts @organamet.

Here's a first... I just got an email because ChatGPT suggested an article I wrote to somebody. Could I send them a copy? Except, I never wrote the article, it doesn't exist. PLEASE realize right now that this tool isn't pulling out cool references for you. It's making plausible titles and matching them to authors names.
@leafs_s they should / could switch left and right left so that the lines and dots don't cross giving a false impression of "distance" 😅(it's their central claim)

A team led by physicist Chien-Shiung Wu obtained the first experimental confirmation of parity violation in the decay of Cobalt-60, #OTD in 1956.

Her theory colleagues received a Nobel for predicting this phenomenon, but she was left off the prize.

@tonic Thank you very much for this explanation. I do believe this is also interesting for metabolic diseases. Mabe it is to early now, but i wil keep it in mind.

"The software is designed to build a record of care that can be translated into billing codes, and this sometimes diverges from the reali- ties of clinical care.29 Several of our respondents voiced the concern that there could be unintended consequences or biased analyses if precision medicine researchers fail to adequately recognize

that much of #EHR data is #BillingData, not #ClinicalData"

Can we bold that, please?

A great paper from @annagloyn and colleagues! Happy we were able to contribute.

Scientists had long assumed parity — that physics proceeds by the same rules for a system and its mirror image — was a fundamental symmetry of Nature. That’s true for electromagnetism and the strong nuclear force, but not for the weak interaction associated with nuclear decays.

Chien-Shiung Wu’s colleagues Chen Ning Yang and Tsung Dao Lee, the theorists who proposed the effect, were rightly awarded the Nobel Prize in 1957. She was left off the prize, of course. Another disappointing exclusion by the Nobel Committee.

At a 1964 MIT symposium, Chien-Shiung Wu commented: “I wonder whether the tiny atoms and nuclei, or the mathematical symbols, or the DNA molecules have any preference for either masculine or feminine treatment.”

Last year the USPS issued stamps featuring Chien-Shiung Wu. And even though they did not use my proposal for the sheet, shown below, you should still buy some.

My arrangement of portraits on the sheet is just a joke meant to remind the viewer that parity is violated — there are more stamps facing one way than the other.

But the USPS sheet (with all portraits facing the same direction) is perhaps a better representation of parity violation in the weak nuclear force. Let me explain.

When we say "parity is violated," it means that some physical process works differently under the sort of left-handed / right-handed swap you get in a mirror's reflection.

The weak nuclear force "maximally" violates parity, in that it only produces neutrinos that are (in a technical sense) left-handed, and never right-handed. This is why first signs of parity violation were first seen in nuclear decays mediated by the weak nuclear force.

So in that sense, you can’t fault USPS for printing a sheet where all the stamps have Chien-Shiung Wu tilting her head slightly to the left.

Chien-Shiung Wu Stamp | USPS.com

This new Forever¼ stamp from the U.S. Postal Service honors Dr. Chien-Shiung Wu (1912–1997), an influential nuclear physicists of the 20th century.

@mcnees how much to the left? Seven percent?
@mcnees (I seem to recall one of Feynman’s stories was about him waiting with baited breath to hear the results of Wu’s experiment, with the hope of finding how far off the measurements were compared to his theory)
@mcnees I have these stamps! Well, not these, but the ones where she’s all facing the same way.
@mcnees They want us to believe that The Past was purely the domain of rich, straight, “Christian” white men, so that they can try to make the future entirely the domain of rich, straight, “Christian” white men
 that is why they constantly try to erase the contributions of everyone else from history. It’s so important we don’t let them.
@mcnees
Is there a maryam mirzakhani like documentary abour Dr Wu?
@mcnees
I was going to post a link the the Wu experiment wiki, buuut I think you've got that covered! Glad I fortuitously stumbled upon the rest of your great thread instead of just favouriting the first post and moving on! đŸ€“
@mcnees The definite proof the #Nobel #Committee violated #GenderParity (equality).
