Isn’t it interesting that at least once a week we say ומפני חטאינו גלינו מארצינו? Not מפני שאבותינו חטאו , not מפני שאויבינו חטאו The tefilla seems to encourage an internal locus of control

Make sure double check that patient’s name before giving a vaccine so it’s not a זריקה שלא לשמה

R. Meilich Biderman tells an awesome story about the Ruzhiner Rebbe that subverts the expectation of a miraculous happy ending

The Ruzhiner zt'l told his chasidim a story of a businessman who lost out on a lucrative business deal because he didn't want to do business before Shacharis. He had many animal skins, and he had a hard time selling them. A customer came to his home and wanted to buy all of them, but it was before Shacharis, and the businessman didn't want to wait. So he left and bought the skins elsewhere.

The chasidim were silent, waiting for the end of the story. The Ruzhiner told them, "I see that you want to hear the end of the story, but that is the end. He kept the halachah, he didn't sell before Shacharis, and he lost a lot of money."

Looks dire, but no worries! The rebbe gets a heavenly message that in the merit of his compassion the child will recover. It turns out that empathy is a potent mystical tool for getting good outcomes 2/n

I find this video fascinating youtube.com/watch?v=hrVQ... The Vurka Rebbe tells his chossid that he can’t perform a miracle to cure his child but he can he cry with him. That would be a lesson about the interpersonal power of empathy, BUT the chossid walks away dejected. 1/n

Here’s my top line overview:

Trump has signed a new EO that puts us firmly into authoritarian overreach territory.
Here's the top line:
1. Calls for political appointees--without science background--to approve all new funding opportunities and **every funded grant** to be sure it aligns with "the President's policy priorities".
2. Any grant that doesn't advance "agency priorities" can be cancelled at any time.
3. Funding cannot be given for research that: promotes "anti-American values", suggests sex isn't binary, and uses any selection for race. (Say good-bye to all c. elegans work!)
4. Funding will be prioritized to institutions that implement the "Gold Standard Science" and have the lowest indirect cost caps.
5. Grant peer-review is fine for now, but seems to be under threat for the future.

Today’s daf!

Herma of Demosthenes from the Athenian Agora, work by Polyeuktos, c. 280 BC, Glyptothek
^ Origin
In the earliest times Greek divinities were worshipped in the form of a heap of stones or a shapeless column of stone or wood. In many parts of Greece there were piles of stones by the sides of roads, especially at their crossings, and on the boundaries of lands. The religious respect paid to such heaps of stones, especially at the meeting of roads, is shown by the custom of each passer-by throwing a stone on to the heap or anointing it with oil. Later there was the addition of a head and phallus to the column,
which became quadrangular (the number four was sacred to Hermes).

Name and origin
The earliest form of the name Hermes is the Mycenaean Greek
*hermahãs, written e-ma-a2 (e-ma-ha) in the Linear B syllabic script. Other forms of the name of Hermes are Hermeias, Hermaön,
Hermãn, Hermaios, and
Hermayos. Most scholars derive Hermes from Greek (herma),
'stone heap’, Hermax, ('heap of stones'), hermaion, ('gift of Hermes'), hermaios hill were holy to Hermes.

Yeah dopamine encodes reward but what about when contingencies shift and behavior needs to be flexible? Turns out VTA GABA neuron activity plays a role, check it out in my first postdoctoral research article here!👇

Have you ever wondered why it’s called “The Three Weeks” but sefira isn’t called “The 7 weeks”? Sefira is literally about the 7 weeks, bain hamitzorim just happens to be 3 weeks long!

This FDA hearing is a sham. There is enough stigma and confusion about treatment for medically-based psychiatric issues. These lies will result in deaths of people who have treatable illnesses.

The group also attacked financial aid programs at Hopkins, including one given by alum Michael Bloomberg, making the medical school free to attend for those from families making under $300,000 a year. About two-thirds of Hopkins medical students, according to the university, qualify for the scholarship.
But the conservative group argued that "it is well recognized that race and ethnicity are inseparable from socioeconomic status," adding that "Johns Hopkins masks racial preferences behind income thresholds."
