Pleased to share my first preprint from my postdoc, where I ask what drives mobile DNA movement between bacterial cells in complex communities like the gut microbiome. To answer this, we built a way to capture mobile DNA in the act of moving between cells, using short-read metagenomics. 🧵

Department of Education FAFSA changes are open for public comment. The changes include requiring trans students to misgender themselves and removes the nonbinary option on forms. Note: comment period is 60 days, and comments are publicly visible. Form here: www.federalregister.gov/documents/20...
WASHINGTON – Today, the U.S. Department of Education published the information collection for the 2026-27 Free Application for Federal Student Aid ( FAFSA®) form in the Federal Register, the first public step in the FAFSA development process. The Department is on track to launch the 2026-27 FAFSA by Oct. 1, 2025 as mandated by the FAFSA Deadline Act.

The Department also announced that current and future FAFSA forms will rightfully reflect the biological reality that there are only two sexes: male and female. Department officials will remove “nonbinary” as a gender identification option from the current year’s FAFSA form.  

“The Trump Administration will correct the failures of the last Administration and ensure students and families can easily access the FAFSA form in a timely manner,” said Acting Under Secretary James Bergeron. “Resolving ongoing problems with the 2024-25 form, reflecting biological reality by referencing sex identifiers, and beginning the process for the 2026-27 form on-time will allow the Department to earn back the trust of the American people. Families and students depend on the FAFSA  form to plan their futures, and any release delays or unnecessary politicization of the form is wholly unacceptable.” Screenshot showing open comment form on federal register site
