President’s Message

So What Does A President Do? I often get asked by students and colleagues some variation of the question: "What is it like to serve as President of the Biophysical So ciety?" A short answer is: "It is not a huge time commitment, but the President does have some power to enact positive changes." The

2. PUI Faculty Award. We want to honor excellence in academic research and mentoring by faculty at a primarily undergraduate institution (PUI), a source of a great number of current and future biophysicists. 3. Early Independent Career Award. This award is for those who have led their own independent research group for fewer than six years and will be based on their contributions during their independence. Accommodations will be made to account for pauses in careers due to child rearing or other reasons. 4. Outstanding Doctoral Research in Biophysics Award. Nominations will require an essay by the nominee explaining their thesis research to a broad audience with scientific inter est. One winner from a U.S.-based institution and one winner from a non-U.S.-based institution will be chosen. 5. Agnes Pockels Award in Lipids and Membrane Biophysics. The Avanti Award in Lipids, awarded since 1997, will be renamed after Agnes Pockels, who determined the size of single lipid molecules and built the precursor for the Lang muir-Blodgett trough. We hope you nominate yourself or other deserving candi dates for these awards (the deadline is May 1, 2024). Our most recent initiative is the Sustainable Future Task Force. President-Elect Gabriela Popescu kindly agreed to chair the task force, which will recommend steps that BPS should take to empower our members who would like to apply their skills and expertise to research related to a sustainable future. They will also look into how to align BPS activities with the goal of achieving a sustainable future. We look forward to taking concrete steps, based on their recommendations, to harness the full potential of biophysics to preserve the planet for future generations! Other responsibilities of the President I will mention are to name the BPS Lecturer and to appoint the Program Chairs for the next Annual Meeting. Elizabeth Villa and Ibrahim Cissé are the Program Chairs who put together an exciting and forward-looking program for the upcoming 2024 Annual Meeting in Philadelphia, and Carolyn Bertozzi , 2022 Nobel lau reate in Chemistry, will give the BPS Lecture. Her lecture on the Monday evening of the Annual Meeting will be followed by a dance and ice cream social (back for the first time since 2020!). Finally, at the Annual Meeting we will also present another exciting lineup of speakers at the President’s Sympo sium on Black in Biophysics. I cannot wait to welcome you to Philadelphia! — Taekjip Ha , President

President presides over BPS Council meetings, held three times a year. Because of the outstanding staff in

Taekjip Ha

the Society office who can turn our decisions into reality, the Council can focus on strategic thinking. We make a conscien tious effort at this by reminding ourselves, at the beginning of Council meetings, of our strategic plan objectives: foster a diverse and inclusive global community, invest in the future of biophysics, enhance the sharing of knowledge, and advocate for biophysics. A great example of a Council-directed initiative that has been put into practice during my term is the three programmatic changes to the Annual Meeting, all designed to increase pre sentation opportunities. First, we created a fifth speaking slot in our symposia, which in the past had four invited speakers for each. These 20+ "Symp Select" speakers are chosen from the abstracts submitted. The response from our member ship was incredible: more than 400 abstracts were submit ted for Symp Select talks from principal investigators of all career stages, from brand new professors to members of the National Academies. Second, those who give 15-minute platform talks are given the option of also presenting a post er. This year, it will add more than 200 presentations to the poster sessions. Third, we added flash talks to the platform sessions. This increased the number of platform speakers by 25%. We hope the additional scientific content will also add to the value of our annual meetings. The Council also just approved the creation of four new awards and the renaming of an existing award. Our motiva tion was to honor the scientific excellence of our members by more fully representing the diversity of research topics, career stages, and geographic locations of our members. The new and renamed awards are: 1. Klaus Schulten and Zaida Luthey-Schulten Computational Biophysics Lecture Award . We thank Zaida Luthey-Schulten, who donated funds to endow this award. This is the only award that comes with a speaking opportunity (as a Symp Select Speaker), which we hope will bring additional visibility.

Patricia O'Hara Area of Research Fluorescence spectroscopy of macromolecules

Institution Amherst College

At-a-Glance

Patricia O'Hara earned her PhD in the late 1970s and went on to be the first woman to be tenured in physical sciences at Amherst College, an institution that had been all male until 1976. Now, as she enters phased retirement, she is spending more time writing. Her textbook Food Chemistry in Small Bites will be published soon.

Patricia O'Hara

Patricia O’Hara grew up in Long Island, New York, the child of an aeronautical engineer father and a mother who worked in the home, caring for the family’s five children. O’Hara’s father passed away when she was young, and her mother eventually remarried a man with eight children of his own. They had two more children together, making O’Hara the exact middle child in a family with 15 kids. She is the only scientist of the bunch and says she fell in love with science as a child through reading “How and Why” books belonging to her brothers. She graduated from Adelphi University in 1976 with a bache lor’s degree in chemistry. From there, she moved to Columbia University, where she earned a master’s degree and PhD in Biophysical Chemistry. “Biophysics wasn’t really a field when I started doing it in graduate school, where I worked with a wonderful physical chemist, Richard Bersohn ,” she shares. “I was part of a small subgroup of his working on proteins, doing laser-induced FRET [fluorescence resonance energy transfer]. My graduate work using lasers to measure FRET and ESR [electron spin resonance] to measure metal binding site prop erties ignited my interest in the broad array of nondestructive assays for looking at biological structure and function.” Upon completion of her PhD, O’Hara undertook a postdoctor al research assistant position with Steven Boxer at Stanford University. She explains, “At Stanford, I explored the effect of protein environment on chromophore properties in the central exon fragment of hemoglobin. I characterized the binding of chlorophyll to this protein subdomain by ESR, NMR [nuclear magnetic resonance], and CIDNIP [chemically induced dynamic nuclear polarization] and grew crystals for x-ray crystallogra phy.” In 1983 she finished her postdoc and started a position at Amherst College as an assistant professor, where she has been since then. “I am the first woman to get tenure in the Physical Sciences at Amherst College, which is a selective liberal arts college and was all male until 1976,” O’Hara remembers. “Being the first woman in an institution that had been all male for 150

years was a challenge, but my experience of having 10 brothers and being by nature very stubborn prepared me well.” She has been a member of the Biophysical Society for 30 years and found the community especially valuable as an early career scientist. She says, “The Biophysical Society Meetings were a lifeline to me at early stages of my career. It is where I met col leagues to collaborate with and where my students gave their first scientific talks and posters.” Employed at a primarily undergraduate institution, O’Hara has worked with many students over the years as they were expe riencing the joy of research for the first time. “I have mentored 75 undergraduate researchers in their senior honors projects and several hundred non-thesis undergraduates,” she reportss. “Watching students learn to love research is always its own reward.” The students’ love of research is matched—and enhanced— by her own. O’Hara says, “‘Turning on the Light’, the title of a paper I wrote for the Journal of Chemical Education and my most-downloaded publication, provides a metaphor for what I love in biophysics. I still feel the awe and wonder when the inner workings of molecular machines and biological processes are revealed.” To young scientists, O’Hara offers this advice: “Find yourself a community that is supportive and welcoming. Be open to getting help and advice from the least likely places.” These days, she is starting phased retirement, winding down four decades of research and doing more writing in its place. She shares, “My future plans involve writing science books at a level that those without technical training can understand. My first book was The Chemical Story of Olive Oil , and I am currently involved in writing about food chemistry—something that might seem far from biophysics but in reality is not. My textbook, Food Chemistry in Small Bites , will be published by the University of California Press in the near future.”

Sarah Rauscher

At a cocktail party of non-scientists, how would you explain what you do? We look at proteins as a machine, and we are aiming to describe in precise detail how this machine works, to develop a blueprint. Viruses and bacteria, for example, target specific proteins and bind with them, while protein mutations are involved in diseases like cancer. Treatment design, therefore, often starts with getting a clear understanding of the structure and dynamics of the pro teins involved in disease. We are using computer simulations to better understand disordered proteins—proteins without a fixed, static structure. Computational methods are perfectly suited to studying the molecular structures of disordered proteins, which cannot be fully investigated through experiments. By simulating these proteins, in collaboration with people who are working on them by using experimental approaches, we can develop a more complete picture of what they look like and how they move. These simulations are computationally challenging and can take on the order of hundreds to thousands of computers for, in some cases, a full year. It took me eight months to run all the simula tions for my first PhD paper. As computational power increases, we can simulate larger systems for longer times. What are you currently working on that excites you? Changes in proteins are at the root of many diseases, and the structure and dynamics of proteins are highly sensitive to even subtle perturbations. For example, disordered proteins are af fected by changes in solution conditions, while protein mutations underlie various diseases. Simulations offer a powerful tool to describe the effects of different types of perturbations at the mo lecular level. My lab is currently working on several projects along these lines. For example, we are studying the effect of molecular crowding on the structure and dynamics of fluorescent proteins in collaboration with Eitan Lerner at the Hebrew University of Jerusalem. We are simulating protein motion in a crystal environ ment in collaboration with Rama Ranganathan at the University of Chicago. Through collaboration, we can relate molecular mecha nisms deciphered by using computational and in vitro approaches to biological processes in vivo, allowing us to make more rapid progress than any of these approaches could make individually.

Biophysical Reports Establishing Riboglow-FLIM to visualize noncoding RNAs inside live zebrafish embryos Nadia Sarfraz, Harrison J. Lee, Morgan K. Rice, Emilia Moscoso, Luke K. Shafik, Eric Glasgow, Suman Ranjit, Ben J. Lambeck, Esther Braselmann “The discovery of fluorescent proteins and subsequent engi neering efforts have revolutionized fields across biology, but comparable tools to visualize RNAs live are critically lacking. Here, the authors demonstrate that the RNA Riboglow-FLIM platform might fill this need. Of note, they establish that Riboglow-FLIM requires fluorescence lifetime imaging mi croscopy (FLIM). The fluorophore element in Riboglow-FLIM is variable, hence a far-red fluorophore for use in live multicel lular environments can be used after careful biophysical char acterization. The authors make use of the common strategy of injecting mammalian cells producing a fluorescence sensor into live embryos as a systematic step of introducing com plexity of a multicellular environment. The authors demon strate that different cellular conditions produce heteroge neous Riboglow-FLIM signatures that can be quantitatively differentiated.”

Around the World: Meet the Fifth Cohort of BPS Ambassadors The Biophysical Society Ambassador Program was created to both enhance BPS content for the global biophysical com munity and provide new pathways into biophysics in home countries. These Ambassadors work in conjunction with BPS committees and staff to offer increased content, program ming, and voice to the international biophysical community. BPS would like to thank the members of our second cohort— Gonzalo de Prat Gay of Argentina, Siti Ngalim of Malaysia, Irep Gozen of Norway, and Canan Atilgan of Turkey—for their dedi cation and service to the international biophysical community. Kumiko Hayashi Japan What do you do professionally? statistical physics and, after completing my PhD, I have applied this knowledge to biological systems, including motor proteins. I have a passion for both programming and experimental work, so I aim to create an environment in my lab where both theoretical and experimental research can coexist and complement each other. I previously held a position as a Council member of the Biophysi cal Society from 2021 to 2023. In Japan, I have extensively orga nized bilateral symposiums with nations including China, Taiwan, Australia, and the United States. At present, I am part of the Executive Organizing Committee for the 21st IUPAB (Internation al Union for Pure and Applied Biophysics) Congress, scheduled to take place in Kyoto this June. What led you to apply for the BPS Ambassador Program? During my tenure on Council, I had limited opportunities to inter act with young researchers and students from Japan, and thus couldn't involve the younger generation in BPS activities as much as I'd have liked. I aspire to play a role in connecting young Japa nese researchers and students not only with the United States but also with many other countries around the world. I believe it would be beneficial to see an increased participation of young Japanese researchers and students in BPS. Kumiko Hayashi I am a professor at the University of Tokyo in Japan. I earned my degree in non-equilibrium

What are your Ambassador Program Goals? My goal is for young researchers and students from Japan to feel closer to BPS. To achieve this, I plan to utilize Zoom meetings to foster interactions between BPS members from around the world and young Japanese researchers and students. I also intend to collaborate with the Japanese Student Chapter. Tell us something fun about yourself? I love coffee. I collect Starbucks City Mugs. Whenever I attend the Annual Meeting, I look forward to buying a new mug!

Part of my efforts are also dedicated to developing new biophysical tools. I have pioneered methods that allow precise single-molecule force measurements within living cells. What led you to apply for the BPS Ambassador Program? Upon moving to the United Arab Emirates (UAE) to join New York University Abu Dhabi (NYUAD) a few years ago, I came to realize that I have to proactively raise awareness about biophysics and its relevance. In contrast to my previous environments, where I was often part of a cohort of biophys icists, I found myself the only biophysicist within the program of physics among many astrophysicists and astroparticle physicists, with only a couple of other biophysicists scat tered within the various other programs. However, with the recruitment of three outstanding new faculty members over the past year, NYUAD is now establishing the foundation for a vibrant biophysics hub. What are your Ambassador Program Goals? In my role as a Biophysical Society Ambassador, I aim to ex tend my experience of promoting biophysics at my institution to a more regional effort and emphasize the unique oppor tunity in the UAE, where numerous higher education insti tutions are in close proximity, making collaborative efforts feasible and meaningful. The accelerating pace of interest in fundamental and applied research in the UAE, coupled with the agility in decision making due to minimal institutional inertia, provides a fertile ground for advancing biophysics. A stronger biophysics presence at this stage and stronger global connections with biophysicists will have a long-lasting impact. Tell us something fun about yourself?

At the UBA, my passion and expertise converge as I lead the development of cutting-edge tools encompassing hardware, software, and novel methodologies at the intersection of microscopy and spectrosco py. These innovations empower us to dissect intricate biological quandaries through a rigorous quantitative lens. What led you to apply for the BPS Ambassador Program? My journey with the BPS Ambassador Program is deeply rooted in my longstanding affiliation with the Biophysical Society. Since 2011, I've actively participated as a devoted student at the BPS Annual Meetings. This dedication to the field led me to take on a pivotal role within the local biophysical chapter of the National Biological Science Society in 2013. In this capacity, I zealously worked towards cultivating national and regional opportunities, providing young scientists with a broader platform to expand their horizons. My commitment extends to my involvement as the Uruguayan representative in the Latin American Federation of Biophysical Societies (LAFeBS) since 2020 and as a founding member and Executive Committee member of the Latin America Bioimaging Consortium (LABI). Through these initiatives, I aim to leverage my regional influence to amplify the presence and impact of the Biophysical Society in my geographical sphere. What are your Ambassador Program Goals? As a BPS Ambassador, I aspire to tighten ties between BPS and regional initiatives like LAFeBS and LABI. Through my extensive involvement with these organizations, I aim to create a favor able ecosystem that enhances young biophysicists’ prospects, helping them access the many BPS activities. My ultimate goal is to promote biophysics-related regional workshops and cours es, spotlighting the exceptional work of many Latin American biophysicists. Tell us something fun about yourself?

Not too long ago, the idea of digitizing lab experiments like we digitized computing would have been unthinkable. The advent of digital microfluidics (DMF) has made this possible by enabling the programming of discrete sample droplets. In recent years, there has been a notable surge in the development of miniaturized microfluidic devices, with the aim of consolidating entire analytical assays into a single chip-like platform to streamline and multiplex laborious conventional laboratory processes. Owing to its myriad advantages, including minimiz ing sample usage, reducing hands-on time, increasing instrument reliability, and eliminating user-to-user variation, DMF has been used to revolutionize processes across many industries. At Nicoya, we saw an opportunity to solve the challenges of label-free technology through integration with DMF, and developed Alto, our digital surface plasmon resonance (SPR) platform. The first of its kind, Alto enhances productivity in the lab for biotherapeutics characterization. From droplets to kinetics: Exploring the fundamentals of digital microfluidics and SPR

DMF is an innovative technology at the intersection of microfluidics and electronics, revolutionizing the way fluids are controlled on a miniature scale. By leveraging an array of individually controlled elec trodes to modulate droplet wettability, DMF trans forms droplets into discrete bits of data that can be programmed as desired. What is digital microfluidics?

The sample droplet and associated buffers are sandwiched between the plates and subjected to an electric field, while the electrode, capacitive dielectric layer, and droplet form the total impedance of the circuit. Droplets are then moved by activating the voltage supply to electrodes adjacent to the droplet and simultaneously deactivating the electrode under the droplet. Read our full blog post to learn more

This enables the execution of complex protocols on precise quantities of liquid on a micro- and nanoscale, while streamlining workflows, minimiz ing hands-on time and eliminating user-to-user variation. DMF devices leverage this simple concept through the intelligent stacking of multiple layers to form a simple circuit. The anatomy of a closed DMF system consists of two parallel plates. The bottom plate contains a substrate, a patterned array of individu ally controllable electrodes, a dielectric insulator to increase capacitance, and a hydrophobic layer to

Nicoya Alto digital SPR

Alto™ is the world’s first and only SPR platform to integrate DMF with nanotechnology-based biosensors, providing a revolutionary approach to real-time interaction analysis. Many common assay methods are automated using Alto’s soft ware, the Nicosystem, and executed within Alto’s self-contained cartridge. Small sample droplets are dispensed, serially diluted, and transported to the sensor surface to determine association kinetics, where they are moved back-and-forth to achieve strong mixing. To determine dissociation kinetics, bu er is transported to the sensor surface and moved back-and-forth. By automating and miniaturizing assays, Alto takes the complexity out of SPR, while equipping your pipeline with a solution that is:

Sample-friendly: Get full kinetics from 2 µL of purified or crude sample, 100-200X less than traditional SPR platforms.

User-friendly: Spend 70% less time at the bench with Alto’s automated sample manipulation and seamless user interface.

Budget-friendly: Minimize lab downtime and maintenance costs with Alto’s fluidics-free operation.

How DMF improves SPR

Minimizes impacts of depletion and accumulation: by using 30X less surface area than conventional SPR platforms, rapid mixing rates, and multiple droplet cycles. Lowers signal artifacts: through DMF-based delivery of samples to sensors. Instead of buffer blank subtraction, Alto uses a detrend ing algorithm to correct for any baseline drift.

Increases precision and accuracy: through automated sample manipulation. Alto demon strated superior precision and accuracy against mechanical pipettes and liquid handlers. Decouples interaction time from sample volume: with droplet

oscillation that enables unlimited sample interaction time without any sample dispersion.

Interested in learning more about Alto digital SPR? Contact us today!

Reduces mass transport limitations: by lower ing the diffusion boundary layer to be equiva lent to fast flow rates and confining the detec tion range to use lower amounts of ligand.

Career Development

Out of Academia and Back Many newly graduated PhDs decide to leave the traditional academic track for another type of job, be it in pharma/bio tech, government, teaching, or publish ing, just to name a few. Some continue

Apart from bench research, there are many other types of jobs in academia where the principles you learn in the private sector would be very useful. These include, but are not limited to, academic administration, scholarly communications, university publishing (often part of the university library), and technology transfer. Explore your options and keep an open mind! — Molly Cule Event Teaches PUI Professors about Useful Software Platform

their career paths within the work environment they chose, while others find their way back to academia. You might wonder how difficult it would be to go back to an academic job after be ing in the private sector or the government or somewhere else. Good news! You can go back. And you will find that the skills and experience you acquired during your time away are very useful in the academic setting, even more so than you imagined. One of my colleagues has an interesting and very convoluted career path. When she started her career, she assumed she would always stay in academia. She got her PhD from a large, well-respected institution, did a postdoc at another top-tier school, and managed to land two faculty positions. She was happy (enough) with her career, perhaps in part because she didn’t know much about other options, ones that don’t involve being at an academic institution. Then she noticed an ad in a scientific journal that a large publisher was looking for people with advanced degrees, no publishing experience necessary. My colleague applied on a whim and ended up getting a job as an editor, working with scientists on books and journals. Ultimately, it turned out to be a fantastic career choice for her. While she was never truly passionate about bench work, she really liked science and this job allowed her to able to contribute to science without actually doing research. Plus, she learned a lot about business, about how to deal with budgets, reading profit and loss statements, and to understand terms such as top and bot tom lines, financial accountability, and return on investment. As my colleague moved up the ranks in the publishing industry, she found that she was getting further and further away from the science. She missed the hands-on content and publishing work. So, she decided to leave her job and just do contract work. Ultimately, one of the contracts was with her alma mater, but in academic publishing, not in bench research. That eventually led to a full-time job at that university, managing a team of edi tors and instructional designers. The time in the private sector taught my colleague a lot about the business world. She often uses the same guiding principles in evaluating projects, devel oping workflows, and navigating organizational changes. She came full circle, returning to her academic roots and even at the same institution where she started her career, in a completely unexpected and very satisfying way, doing the type of work she loves.

In a prior primarily undergraduate insti tution (PUI) networking event summary, some of the challenges and potential solutions facing todays PUI professors were discussed. In an aim to expand the resources that these professors have available to them, Adam Schuyler , assistant professor at the University of Connecticut, was kind enough to present a tutorial and

Q&A session about NRMbox specifically tailored to PUI pro fessors at the most recent event. Developed by the National Center for Biomolecular NMR Data Processing and Analysis, NMRbox provides a comprehensive and integrated software platform that includes a variety of tools and software packag es for processing, analyzing, and interpreting data, and is ideal for biophysics research and education. NMRbox is completely free and can give each user access to a personal virtual desktop along with powerful, cloud-accessed computational resources. However, while extra processing power will always be useful, the heart of its appeal for re searchers in PUIs lies in its inclusive access to a diverse array of programs. The platform's arsenal includes, among other things, free access to powerful tools like MatLab, open ing educational avenues without the burden of prohibitive software costs. This can enable undergraduates to delve into complex structural investigations and can alleviate many of the issues that researchers face regarding replication in all computational fields. Additionally, NMRbox provides a wealth of educational resources that professors can utilize in both the classroom and the lab. These tools can help facilitate a smooth onboarding process, reducing the strain on labs that need to train new undergraduates each year. We hope that this information can help other PUI professors, and we look forward to exploring further resources in future

Student 2: It can depend on your principal investigator (PI). When doing lab rotations, pay attention to the environment and talk to the students in the lab to see what they think of the expectations and work-life balance. It’s not worth it to struggle through with a PI who will not be supportive or who will require too many working hours, even if the research is interesting. Student 3: Ask up front if a PI is hands-on or hands-off. Each person might have a different preference for which they would rather work with, but it is helpful to know if you should expect detailed weekly assignments with lots of check-ins, or a PI who is more hands-off and expects the lab to run. That can be challenging if you aren’t good at motivating yourself; you might not be very productive without structure and that can catch up to you. Know what works for you. Student 4: Having a good work-life balance does depend a lot on the PI. Be very careful when doing rotations to ask lab members, and if they’re not transparent about it that can show that the lab doesn’t have a good culture. It’s not just about them interviewing you—you’re also interviewing them. Be really picky about your mentor and PI—picking a mentor is almost like picking a spouse! Posanno: Your relationship with your PI does last longer than most marriages in the U.S.! This is great advice from the students. It’s important to know how to pick the right PI for you—it’s about chemistry and working styles. Remem ber that people don’t have access to the information inside your head. We think everything is so obvious, but if you work best first thing in the morning or late at night, no one will know unless you tell them. So many mismatches with labs and work-life balance come from not sharing information. In the absence of context, that’s when people form judgments. If you’re providing context or an explanation for things that people don’t see—that can help avoid some PI problems or judgments forming. There will be another similar session in the fall of 2024.

events. If you have a topic or tool that you think could benefit the members of the PUI Network, then please reach out to Ethan Rogers-Yosebashvili at eyosebashvili@biophysics.org. The PUI Network will be hosting its first ever Annual Meeting Mixer, and we would love to see you there! This event will be held Sunday, February 11, 2024 from 5:00 to 7:00 PM during the BPS Annual Meeting in Philadelphia. Virtual Graduate School Panel Answers Questions for Students The Membership Committee sponsored a Virtual Graduate School Panel Discussion on November 1. More than 150 students from 22 countries registered to attend. Three advi sor-level panelists participated: Melanie Cocco , Membership Committee Chair; Yadilette Rivera-Colón , Education Committee Chair, and Shana Posanno . Four graduate students also joined as panelists to answer questions from the audience. To keep things candid, the session was not recorded so that the cur rent students could speak openly about their experiences. The session was scheduled for one hour, but ended up lasting a half an hour longer because there were still so many ques tions being asked. There were more than 30 questions, many of which were answered in detail with advice from more than one panelist. One of the key questions and the answers from the panelists is summarized below. Q: Is it hard to find a good work-life balance? Student 1: Graduate school is like an endurance test—it is possible to wear out quickly. You may need to be at the lab late and that can be a big challenge in maintaining connec tions with people. As long as you have a schedule in mind, that can help maintain a balance. Make sure you’re making healthy decisions. It’s sometimes better to leave the lab ear lier rather than stay late; it’s better to not make mistakes and feel better the next day to start fresh.
