Bioengineering The 4th Annual Bioengineering Subgroup Symposium will be held Saturday, March 2, 2019, at the Baltimore Convention Center, beginning at 9:00 AM. The program will feature prominent speakers who use biophysical principles in various bioengineering applications. Invited speakers for this year include Ka Yee Lee (University of Chicago), Susan Daniel (Cornell University), Mark Uline (Univer- sity of South Carolina), Daniel Hammer (University of Penn- sylvania), and Jennifer Elisseeff (Johns Hopkins University). A trainee talk will also be featured from the abstracts submitted to the Bioengineering Subgroup. I would like to gratefully acknowledge the journal APL Bioengineering for their support of the subgroup symposium for the 2019 Annual Meeting. The Bioengineering Subgroup has made great strides over the past four years. The number of members has increased from 239 (44 paid members) in 2016 to 439 (126 paid mem- bers) by the end of November 2018. This year we have 16 posters in the Student Research Achievement Award poster competition, which is also a significant increase compared to our first year. All subgroup members are encouraged to attend the symposium and the poster session and I would encourage you to support the subgroup by becoming a paid member, if you have not already done so. Finally, I would like to point out that we are looking for candi- dates for the next president and treasurer for the subgroup. The list of candidates should be finalized by January 18. If you are interested in being involved in the subgroup in any of these roles, please feel free to email me (farnoud@ohio.edu) or Stacey Wendelbo (swendelbo@biophysics.org). If you have any questions regarding what these roles entail, feel free to contact us as well. Thank you for your ongoing support and I look forward to seeing you all in March! — Amir Farnoud , Bioengineering Subgroup Chair

Exocytosis/Endocytosis The 2019 Exocytosis/Endocytosis Subgroup Symposium is scheduled for Saturday, March 2, at the Baltimore Convention Center as part of the Biophysical Society Annual Meeting. The theme for this year’s symposium is, “From Molecule to Mechanism: New Insights into the Dynamics of Vesicle Fusion and Recycling.” Featured speakers are: Nils Brose , Max Planck Institute for Experimental Medicine Dynamic Control of Vesicle Priming in Synaptic Short-term Plas- ticity

Membrane Transport We look forward to our subgroup symposium on Saturday, March 2, 2019, in Baltimore, Maryland, during the Annual Meeting of the Biophysical Society. The symposium will be 1:25 PM to 5:00 PM; dinner starts at 6:30 PM. All members of the Biophysical Society are welcome. Don’t forget to show your support by registering for the subgroup. To give you a flavor of the upcoming talks, here are highlights from three of our symposium speakers: Tom Miller (Fig. 1), Michael Grabe (Fig. 2), and Crina Nimigean (Fig. 3). See the December BPS Bulletin for highlights from our other speakers: Chris Miller and Cristina Paulino . Also, congratulations to Chris Miller on winning the contest for the subgroup image. Check out the intriguing image he chose to represent the mechanism of ion permeation through fluoride ion channels at: https:/www.biophysics.org/sub- groups. Hope to see you on Saturday afternoon in Baltimore! — Susan Rempe , Chair; Ming Zhou , Vice Chair; Lucie Delemotte , Secretary and Treasurer

In addition, several short talks from trainees will be selected from the abstracts submitted for the Annual Meeting. A clos- ing banquet dinner will be held at Eat Bertha’s Mussels, 734 S. Broadway, Baltimore, and will allow for plenty of network- ing and scientific interactions after the symposium. The orga- nizers invite all members of the Biophysical Society to join us for what promises to be an outstanding day of cutting-edge science and camaraderie. — Amy Lee , Exo/Endo Subgroup Chair

Use Your Expertise to Make a Difference! Be an inspiration to your community and help change the lives of those interested in or studying science. The FaB Network is free and accessible by members and non- members, but only BPS members may add their names to FaB. The network is designed to provide the best match to users searching for a biophysicist for any of the afore- mentioned activities. To join FaB, login or create your myBPS account and get involved. Help build this new network by signing up today. For more information, visit biophysics.org/ get-involved.

NewMembership Benefit in 2019 Beginning in 2019, Society membership will include one complimentary BPS subgroup membership. Members may always join additional subgroups for $20 each. As before, emeritus and student members may join as many subgroups as they wish for no additional fee. BPS subgroups are an integral part of the Society, providing year-round opportunities for members to meet, work, network, and collaborate within their more focused communities while still enjoying the rich benefits of belonging to the broader biophysics world of the Biophysical Society. If you are interested in joining or learning more about additional subgroups, please visit www.biophysics.org/subgroups.

Fig. 1 A key step in delivery of cellular pro- teins to other compartments of the cell is the efficient transport, or translocation, of the newly synthesized proteins across phos- pholipid membranes. Protein translocation involves a delicate balance between process- es that range from atomistic interactions and fluctuations to macromolecular transport.
