Seems we have to lean on operationalizing for a lot of animal work.

How would you propose to improve on this e.g for the rodent attention or fly sleep task you mentioned?

Each of the types of papers
in this list are useful in their own right, just a tongue in cheek comment :)

the explosion of any technique inevitably brings an avalanche of papers that misuse, over-claim, or rediscover things.

State them clearly and in direct response to pre selected RFK quotes, preferably ones that have been repeated many times.

Second half should be about making NIHs financial payoff (dollar in vs dollar out) extremely clear to the public

Jonna Singh @jonnasingh.bsky.social · Jun 11

Reach out to the top 25 scientists in the main “contention” areas (vaccines / autism / chronic diseases / cancer / neurodegeneration) and collect the list of findings/citations that most clearly contradict RFKs previous statements and policies (there is a wealth of these that are widely agreed upon)

to what degree are people *actually* excited about a copy paste approach to learning from these connectors?

Most of the interest I see is the high level interest you mention, or neuroscientists excited about modeling the brain more accurately.

Wild!

Stephen, Praneel and their team use fluorescence lifetime imaging and various manipulations to show that, in male mice, both mating drive and hypothalamic tonic dopamine release drop after a successful mating and gradually recover over the next week, paralleling the recovery in sperm count.

I am excited to share our preprint on how hypothalamic dopamine neurons govern slow changes in motivation over days! Below are our findings:

Slow-Timescale Regulation of Dopamine Release and Mating Drive over Days

The rise and fall of motivational states may take place over timescales as long as many days. We used mouse mating behavior to model how the brain orchestrates slow-timescale changes in motivation. Ma...

P.S: Praneel will be applying to MD PhD and is an absolute beast. Systems neuro labs don’t miss out!!

I know it's not very helpful, but I find myself thinking about those who criticized Nature's and Scientific American's Harris endorsement on the grounds that "science should stay out of politics." I think about those people quite a lot.

It’s is practically guaranteed that what is happening to Harvard WILL happen to your favorite R1 institution if we don’t continue to engage our local representatives.

Reminder: Bluesky is an echo chamber.

As useful as it is to get informed and feel support on here, it’s time to get uncomfortable and speak up *in real life*.

Talk to those who are not here. Be ready to explain these catastrophes. Add YOUR grain of salt to the mobilization process. It matters.

The tone is not nearly alarming enough to be reflective of reality. It’s a full blown blood bath that has torn down decades of progress.

This should be front and center as the biggest sacrilege committed by these braindead bigots.

Delighted that our work on positional memory is now published. We asked how axolotl cells 'know' which part of the limb to regenerate after injury.

Under 65 years old? No Novovax COVID vaccine for you this year.

As expected, the Republicans have enabled RFK Jr. and his coterie of antivax grifters to take away your right to make your own medical decisions in consultation with your doctor.

Gift Link: www.nytimes.com/2025/05/17/h...

The new restriction will sharply limit access to the Novavax vaccine for people under 65 who are in good health. It may leave Americans who do not have underlying conditions at risk if a more virulent version of the coronavirus were to emerge. It could also limit options for people who want the vaccine for a wide array of reasons, including to protect a vulnerable loved one.

Dozens of responses to my essay summarized.

1. Why aren’t scientists in an uproar?
2. Most Americans don't know that defunding science will make their lives worse.

Bluesky, tell your neighbors, science matters. Scientists, roar.
