    molpigs Team: 4 years in the sty

    On this episode of the molpigs Podcast we introduce the new members of the molpigs team and re-introduce the long-term hosts, Boya Wang and Erik Poppleton. Hannah and Georgeos have stepped down from the podcast team, though Hannah continues to support us from behind the scenes. Joining us today are our two new members, Spencer Winter and Anuhya Edupuganti. On this episode we interview each other about why we're here, our strengths, our dreams, and why you should host boardgame nights at DNA conferences. A couple of factual errata:When Erik is talking about annealing ramps for DNA origami crystal assemblies, he says that they use a zigzag temperature around the nucleation temperature. In fact, they just ran extremely slow annealing ramps around the nucleation temperature (see the SI of the paper linked below)The word for the plant cellular structure that Erik can't remember is plasmodesmata, not desmosome. Links to the papers discussed in this episode:Anuhya's favorite paper: Isothermal self-assembly of multicomponent and evolutive DNA nanostructures by Rossi-Gendron et. al. (2023) https://www.nature.com/articles/s41565-023-01468-2Spencer's favorite paper: A deoxyribozyme-based molecular automaton by Stojanovic & Stefanovic (2003) https://www.nature.com/articles/nbt862Boya's favorite paper: Scaling Up Digital Circuit Computation with DNA Strand Displacement Cascades by Qian & Winfree (2011) https://www.science.org/doi/10.1126/science.1200520Erik's favorite paper: Binding to nanopatterned antigens is dominated by the spatial tolerance of antibodies by Shaw et. al.

    Jacob Majikes: The boring, basic details of molecular programming

    On this episode the molpigs team talks with Jacob Majikes, the ‘boring materials physics’ expert of the DNA origami field. We discuss the incentive structures of the field, Hatch Act violations*, and how guinea pig bedding relates to biologics production. He explains to us how the National Institute of Standards and Technology became interested in DNA origami and how defining ‘yield’ of a structure is a more challenging problem than you would expect. He also shares the excitement and challenges of organizing FNANO, one of DNA origami’s annual conferences, and how he thinks the conferences will develop into the future. * Jacob is not entirely sure on his description of the Hatch Act! --- Jacob Majikes is a Research Scientist in the Microsystems and Nanotechnology Division of NIST. He received his B.S. and Ph.D. in materials science and engineering from North Carolina State University. His doctoral research focused on probing the folding/assembly of DNA origami nanostructures. Jacob is working with Alex Liddle to develop metrics to quantify the yield of discrete DNA nanostructures and to understand the effect of structure design on yield. ---Find more information at the episode page here:https://podcast.molpi.gs/media/majikes-j-24e8817ee9f1e8e6/

    Erika DeBenedictis

    This week’s podcast is with Erika DeBenedictis, a new principal investigator who is founding her lab at the Crick Institute in London. Her lab will focus around the broad field of bioautomation, but before talking about any of that, we delve into her past. Erika is just another one in a long string of podcast guests who has had an unconventional entry into the field of molecular programming! She started her scientific career interested in space science, telling us that her interest was kindled as a child because of the accessibility of this field to anyone. This led her to work at NASA’s Jet Propulsion Laboratory. Afterwards she talks about her time as a PhD student in Kevin Esvelt’s lab working on massively parallelised directed evolution, harnessing the power of robotics in order to develop her technique known as PRANCE. She talks about the use of these techniques in expanding the genetic code, and the main hurdles in doing so. We then move on to her post-doc at David Baker’s lab in Washington, where she worked on using machine learning for de novo protein engineering. At the same time we talk about the place of robots in modern laboratories, whether they will replace all hand pipettes (and wet lab scientists!), and the feasibility of cloud laboratories in making science more accessible. Finally we move on to the start of Erika’s new lab at the Crick Institute, her vision for what she wants to do, and ultimately the bioautomation challenge, which is a programme spearheaded by her to get bioautomation equipment into more laboratories to accelerate research. --- Erika began her science career as a computational physicist and astronomer and worked on space mission design at NASA’s Jet Propulsion Laboratory. She received a BS in Computer science from Caltech in 2014. She then worked at Dropbox as a software engineer and at D. E. Shaw Research on computational biophysics. She received a PhD in Biological Engineering from MIT in 2020, working with Kevin Esvelt. Erika’s research focused on developing techniques for robotics-accelerated evolution (PRANCE) and applying these techniques to quadruplet codon genetic code expansion and origin of life research in E. coli. Her postdoc in David Baker’s lab at the Institute for Protein Design at the University of Washington focused on using machine learning techniques to systematically engineer de novo proteins. In 2022, she launched the Bioautomation Challenge, a program designed to make experimental life science more reproducible, scalable and sharable by giving researchers access to programmable experiments. She now leads the Biodesign Laboratory at the Francis Crick Institute in London, UK. ---Find more information at the episode page here:https://podcast.molpi.gs/media/debenedictis-e-59f6feebc1495d48/

    Grigory Tikhomirov

    In this episode the molpigs team talks with Greg Tikhomirov about his experience starting a new molecular programming lab and his visions for “a new nanotechnology”. We learn about his journey from wanting to build large, beautiful molecules to his work at the interface between molecular design and material science. Greg Tikhomirov is an assistant professor in Electrical Engineering and Computer Sciences, with a background in chemistry, bioengineering, medicine, and nanotechnology. He has a longstanding dream to engineer life-like artificial systems, motivated by the realization that incomprehensible natural complexity arises from comprehensible fundamental laws. Ti Lab at Berkeley is pursuing the design and fabrication of devices with atomic precision by combining the strengths of rational top-down engineering and bottom-up biomolecular assembly. A key goal is to adopt the powerful but still proof-of-concept self-assembly approaches of DNA nanotechnology to engineer new, useful devices. ---Find more information at the episode page here:https://podcast.molpi.gs/media/tikhomirov-g-cb5ef2637de05b5b/
