Interested in teaching your kids or students about bacteria and how they interact to collectively respond to antibiotics? The @sj4k.bsky.social worked with us to adapt our recent paper into an article to help teens think about social interactions in bacterial communities:

Researchers show how bacteria living close together form patterns, share protection, and respond to antibiotics in surprising ways.

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

Evolution of antibiotic resistance #AMR can lead to collateral resistance/sensitivity to other drugs; @jeffmaltas.bsky.social &co show that these effects can fluctuate over time, needing precise timing & stochastic control models to optimize treatment strategies 🧪 @plosbiology.org plos.io/3C2Ao1y
Success of switching to a second antibiotic is contingent on temporally dynamic collateral effects. Top: Twenty replicate populations of E. faecalis V583 were exposed to increasing concentrations of the antibiotic ceftriaxone over the course of 14 days via serial passage. At the end of each day, a sample of the population was isolated and cultured in a range of doxycycline concentrations for 24 h. Middle: Density (OD) after 24 h versus drug (DOX) concentration for all 20 populations (light gray), and the mean over the 20 populations (dark black) at different days of the evolution experiment. Bottom left: Average sensitivity over 20 populations (error bar standard error of the mean) at different time points. Bottom right: Collateral effects; dashed region highlights a transient six-day window where collateral sensitivity is more pronounced.
