I'm stoked to have this long-term and highly collaborative effort out in the wild. We present an experimental evolution system to quantitatively study the rapid evolutionary dynamics of B-cell affinity maturation. These evolutionary mechanisms underpin antibody responses and immune memory formation.

Biophysicists are realizing that there is an undervalued element at play in early development: Aside from genes, mechanical forces also steer the growth of embryos. @annademming.bsky.social reports: www.quantamagazine.org/genes-have-h...
Genes Have Harnessed Physics to Help Grow Living Things | Quanta Magazine
The same pulling force that causes “tears” in a glass of wine also shapes embryos. It’s another example of how genes exploit mechanical forces for growth and development.

Some problems have simple solutions. This new “Compact for Academic Excellence in Higher Education” is one. The answer is simply saying no.
Simple does not mean easy. But Brown, Dartmouth, MIT, Vanderbilt, Univ of AZ, UPenn, USC, UT Austin & UVA must understand what they’ll lose if they sign on.

Here at UW Genome Sciences, PhD students take a summer course at the end of 1st year to write NSF GRFP proposals. They finished refining proposals on Wednesday, the first day of Autumn quarter, marking the start of their 2nd year. With NSF's announcement, the entire cohort is suddenly ineligible.
Today was a hard day for Ph.D. students who found out that they can no longer apply for NSF's prestigious Graduate Research Fellowship Program. "Devastating“ was how one student described it to me. #GradSchool #NSFGRFP

This piece proposes radical measures—equal and opposite to “put AI in everything” initiatives at UW and elsewhere—to emulate the college experience at the turn of the millennium. Nostalgia aside, I think I benefited from slowly titrated tech, encountering AI tools only after learning how to think.

The term 'affinity maturation' understates the influence of somatic hypermutation
