Cell models need information-rich data and useful inductive bias
“So what I think is possible now is an information theoretic model of the cell.”
at 16:38 - 26:12
A laser phase plate reveals molecules inside living cells
“what this really gets you is the ability to look. And so the big application is cryo-electron tomography, which is basically sectioning the cell”
at 26:52 - 48:56
Health records alone may reveal correlations, not causes
“because if you don't have the right basis, basically what you're going to learn is a bunch of correlations.”
at 50:07 - 22:47
Biohub's initiative targets hundreds of billions of cells
“be able to do that at the scale of hundreds of billions or more cells.”
at 25:06 - 30:25
Biohub is building imaging tools across biological scales
“track a developing zebrafish embryo over time and actually see and track every single cell”
at 34:48 - 38:37
Protein models benefit from training across evolution
“And so there's, I think, something really powerful in this idea of generalization and transfer.”
at 41:02 - 45:58
A coordinated effort could map cellular health and disease in five years
“within five years with a really focused coordinated effort, we can have, you know, a pretty comprehensive map there.”
at 47:51 - 42:17
Biology models need lab-based verification loops
“ask the question perform the experiment learn from the experiment improve its understanding propose a better experiment”
