We are pleased to announce that the submission site is now open for BUCLD 50! Please read below for important announcements and submission instructions. Request for Donations for the Diversity Travel Fellowship: In March, the NIH grant that funded our Diversity Travel Fellowship was terminated. This grant provided $10,000 annually, which we used to support approximately eight student fellowship recipients. The fellowship covered all travel costs for recipients, who are also invited to special events and networking opportunities. We have submitted an appeal to NIH that argues for a reversal of their termination decision. Unfortunately, a reversal is unlikely, and so we are also seeking community support in hopes that we can continue to offer the travel fellowship this year. If you would like to provide support, please make a donation here: https://www.bu.edu/bucld/donations/ Commemorate BUCLD 50: Share your Photos, Videos, and other Memories! To mark BUCLD’s 50th anniversary, we will be putting together some retrospective material that will be displayed during the conference. If you have photos, videos, or other digital material regarding BUCLD that you would like to contribute, please upload them here: https://tinyurl.com/BUCLD50-memories Call for Submissions for Talks and Posters: Submissions are open for 500-word abstracts for 20-minute talks and posters. Submissions that present work related to language acquisition from any theoretical perspective will be fully considered. Abstracts are limited to 500 words and must not exceed two pages. A suggested format and style for abstracts is available here<http://www.bu.edu/bucld/abstracts/abstract-format/>. Please submit your abstracts starting on April 1, 2025 using this submission portal<https://www.bu.edu/bucld/abstracts/abstract-submission/> on our website.

BUCLD 50 Call for Special Symposium Proposals: To commemorate our 50th anniversary, we are seeking 1000-word proposals for 90-minute symposia of two kinds: retrospective or prospective. Retrospective proposals should reflect on how language development research has grown over the years and where we have made substantial progress. Prospective proposals should address evidence of how the field is currently changing and discuss how the field is likely to continue evolving. Prospective symposia could focus on new methods afforded by technology, inclusion of expanded and more diverse populations in research, theory building, or other areas of likely growth. All proposals should include a list of participants, topics, format, and at least one organizer. Send submissions to langconf@bu.edu<mailto:langconf@bu.edu> with the title “BUCLD 50 Special Symposium” in the subject line. All submissions are due June 1, 2025 by midnight anywhere on Earth. Symposia decisions will be made in July. BUCLD 50 Organizing Committee
