In all seriousness, lock her up. (Lock them all up, of course, but her too.)
Megyn Kelly: "I know somebody very close to this case…Jeffrey Epstein, in this person's view, was not a pedophile…He was into the barely legal type, like he liked 15 year old girls…He wasn't into like 8 year olds…There's a difference between a 15 year old and a 5 year old."

Just got an email from my SRO for the study section that was missed in October. Good news is that they are trying to reschedule ASAP (Dec/Jan). The bad news is that CSR is mandating that only the the top third (not half) of applications will get discussed for the next 2 rounds.

I just got an email from a former mentee telling me that one dinner conversation changed how he writes papers♥️
I told him: “just write the paper, get it out—the next one will be better, and the next even better.”
Perfectionism is a trap (and a way to procrastinate...:))

My takeaway from every new Epstein revelation is that some powerful people victimized many powerless young women, many more knew, some actively enabled it--and we're still being told that MeToo and accountability for sexual violence have gone too far

Said it before, will say it again, the Epstein Files are THE story.
Not the only story, but it's the story which can and will weaken and possibly bring down Trump and now the GOP and even many powerful man who have escaped accountability for years.
Keep pushing and digging.

Estrogen modulates reward prediction errors and reinforcement learning - Nature Neuroscience
Dopamine encoding of reward prediction errors naturally fluctuates over females’ reproductive cycles with estrogenic signaling due to reduced expression of dopamine reuptake proteins.

From street marches to court battles to the ballot box - we’ve challenged the power of this exceptionally unpopular president.
The lesson from each success we've had is that we need to ramp the political pressure up, always up, not back down, now more than ever.
