When sex chromosomes turnover, they can reset the rules of genomic conflict.
New preprint exploring how turnover reshapes barriers to gene flow through an “escape-hatch” model for mitonuclear conflict.

New today: We're petitioning NSF to revert GRFP eligibility criteria to last year's terms, to avoid pulling the rug out from under the earliest of early-career scientists who had every reason to think they'd be able to apply this year. Sign and spread the word!

The GRFP announcement from NSF cuts out an entire cohort of 2nd year students from consideration, without warning. This is so deeply unfair that it warrants a formal protest from the scientific community. If someone wants to work with me to craft an open letter and solicit signatures, LMK.

As others have pointed out, the fellowship is now available only to 1st year grad students. (Left is last year, right is this year)
Be a U.S. citizen, national, or permanent resident Intend to enroll or be enrolled full-time in a research-based Master's or doctoral degree program in an eligible Field of Study in STEM or STEM education (See Appendix and Section IV.3 for eligible Fields of Study Never previously accepted a Graduate Research Fellowship Declined any previously offered Graduate Research Fellowship by the acceptance deadline Never previously applied to GRFP while enrolled in a graduate degree program Never earned a doctoral or terminal degree in any field Have completed no more than one academic year (according to institution's academic calendar) while enrolled in a graduate degree program (non-degree coursework must be clearly identified in the transcript and does not count toward this limit) Individuals holding joint Bachelor's-Master's degrees who did not apply while enrolled in the joint program, may apply as second-year graduate applicants if enrolled in an eligible doctoral program the beginning of the academic year immediately following the academic award year of the joint degree Individuals with prior graduate enrollment who have: (i) completed more than one academic year in any graduate degree-granting program, (ii) earned a previous master's degree of any kind (see guidance for joint Bachelor's-Master's degree-holders above), or (iii) earned a professional degree must meet the following requirements: not enrolled in a graduate degree program at application deadline two or more consecutive years past graduate degree enrollment or completion at the application deadline Not be a current NSF employee. Must, at the time of submission, be a U.S. citizen, national, or a permanent resident (“green-card” holder) Must intend to enroll or be enrolled in an eligible research-based master's or doctoral degree program in an eligible field of study in STEM, including STEM education (See Appendix and Section IV.3 for eligible Fields of Study); Never have previously accepted a Graduate Research Fellowship; Have declined any previously offered Graduate Research Fellowship by the declination deadline (if applicable); Have completed less than one academic year in a graduate degree program (according to the institution’s academic calendar; non-degree coursework must be clearly identified in the transcript and does not count toward this limit). This means individuals in the following statuses at the time of application are eligible: Undergraduate in the final (senior) year of a bachelor’s degree program Bachelor’s degree-holder with NO enrollment in a graduate degree program (non-degree graduate coursework allowed) Individual enrolled in a joint bachelor’s-master’s degree program with at least three undergraduate years completed First-year graduate student in their first graduate degree program with less than one academic year completed in the degree program (according to institution’s academic calendar) Individuals enrolled in joint bachelor’s-master’s degree programs are considered graduate students. For GRFP, joint bachelor’s-master’s degrees are defined as degrees concurrently pursued and awarded. Not be a current NSF employee.

First pop gen paper from our lab! We find repeated evolutionary turn over of sex chromosomes in darters contributes to reproductive isolation. Turnover may be an escape hatch to resolve mitonuclear conflict & neo sex chromosomes evolved via a rare recessive mutation. www.biorxiv.org/content/10.1...
Top left: Results of genome-wide association study (GWAS) for sex in E. caeruleum, E. radiosum, and E. spectabile showing sex chromosome turnover has occurred repeatedly. Top right: Phylogeny showing sex chromosome turnover in darters and non-darter percids. Chromosome 9 is the putative ancestral sex chromosome, shared by Perca flavescens and multiple members of the orangethroat darter complex (e.g., E. spectabile, E. pulchellum). Bottom: Schematic depicting repeated turnover of sex chromosomes as a mechanism to resolve mitonuclear conflict and promote speciation.

Trump admin planning to change student visas from lasting for duration of academic program to fixed 4-yr term, and then much harder to renew
Could destroy US ability to attract global talent, particularly those seeking advanced degrees in STEM. The median time to complete a PhD is 5.7 yrs per NSF.

Why do males and females often differ in traits?
The expected answer: selection.
But our new paper in GENETICS shows that genetic drift alone can generate sexual dimorphism — even when male & female optima are the same

Not sure how many scientists here have tried Claude Code or similar command line coding assistants. I had a complicated family property tax problem that was best solved by a brute force Monte Carlo simulation approach, so I spent a few days coding up and analyzing a model with Claude Code.
