Today my @nytimes.com colleagues and I are launching a new series called Lost Science. We interview US scientists who can no longer discover something new about our world, thanks to this year‘s cuts. Here is my first interview with a scientist who studied bees and fires. Gift link: nyti.ms/3IWXbiE

Awesome science!

Happy to be back @princeton.edu , where I received fabulous PhD training, to give a talk in MolBio and serve as a Health Science panelist for the Many Minds Many Stripes 125th Graduate Anniversary celebration!

Rutgers peeps: David Katz is presenting this exciting work tomorrow Oct 8 at 2pm in Waksman 1001. #celegans

Very excited to share our very exciting story on how misinherited chromatin affects individual cells to cause a behavior defect in C. elegans (a thread👇) www.pnas.org/doi/10.1073/...

If the same thing is true in the corresponding human patients, might it be possible to revert cognitive/behavior deficits in the human patients also?

So, expressing germline genes in neurons can block their function in a way that is reversible if you shut off the inappropriate transcription

Turning off the ectopic germline gene expression in the neurons of worms that already have a chemotaxis behavior defect, reverses the behavior back to normal

So, could the chemotaxis behavior defect be due to an ongoing defect in an intact nervous system? If so, might it be possible to reverse the chemotaxis behavior defect even after the nervous system has fully formed?

The invariant C. elegans lineage and adult nervous system provide the perfect opportunity to find out how every cell responds to inappropriately inherited chromatin and altered transcription

David Katz @katzlab.bsky.social · 7d

Ever wonder how something as broad as a chromatin mutant causes cell specific phenotypes?

So proud of my graduate student Monica Reeves for winning program student of the year in the Genetics and Molecular Biology program at Emory University @emory-gmb.bsky.social

Really cool. Looking forward to reading it. The Peters’ lab publishes amazing science.

David Katz @katzlab.bsky.social · Sep 9

A lot of important views expressed here. I am just curious how the potential to flood the zone with fake papers feeds into all of this?

Stand up for science. Stand up as if our lives and our economy depend on it. Because, actually, they do. #standupforscience

Thank you. I will put my head down and continue to do the best science that I can.
