    NMT4: Jane Panangaden
    May 7 2021
    In Chapter 4 of "Not My Thesis," Jane Panangaden explains the abstract world of pure math and the delights of exploring it, as well as her work advocating for tenants' rights in Pasadena. While dividing her time between writing proofs and legislation, Jane grapples with how we apply our skills, technical or otherwise, to bring a different world into existence. She asks us to consider: why do math? You can find out more about the Pasadena Tenants Union, including the ordinance they wrote, here (http://pasadenatenantsunion.org/). Read about what the Socialists of Caltech are up to here (https://socialistsofcaltech.com/). To learn more about the history of eugenics at Caltech, check out this Caltech Letters viewpoint article (https://caltechletters.org/viewpoints/rename-millikan). In recognition of this history, Caltech recently decided (https://www.caltech.edu/about/news/caltech-to-remove-the-names-of-robert-a-millikan-and-five-other-eugenics-proponents) to remove the names of some of the eugenicists from campus buildings.

    NMT 3: Mia de los Reyes
    Aug 7 2020
    In Chapter 3 of Not My Thesis, Mia de los Reyes discusses the galaxies lurking in the empty parts of space, the constraint of light, and how she’s helped expand the membership of the scientific community. Astronomy, Mia reminds us, may not always be useful. But it is certainly cool. You can find more information about galaxies eating each other here (https://www.universetoday.com/108696/vampire-galaxy-sucks-star-forming-gas-from-its-neighbors/) and read about our collision with Andromeda here (https://www.space.com/15949-milkyway-galaxy-crash-andromeda-hubble.html). If you want to hear Mia or her fellow astronomers amaze you even more with the wonders of the universe, check out Astronomy on Tap or other online events (https://www.astro.caltech.edu/outreach/). And if you are interested in making your scientific discipline more accepting, check out Mia’s write up on inclusivity (https://astrobites.org/2018/05/25/lgbtq-inclusivity-in-astronomy/). To read about mental health in academia, see this Nature article (https://www.nature.com/articles/nbt.4089) or this Caltech Letters one (https://caltechletters.org/viewpoints/mental-health). Caltech Letters has a number of articles by other astronomers. Check them out!

  • Biosphere 7: Mistakes

    Biosphere 7: Mistakes
    Jul 24 2020
    How does evolution give rise to new features of living things? Mistakes drive the vast diversity of life on earth through mutations (random errors in the information carrying molecules of a cell). A core question of evolutionary biology is how hard it is to make useful, new biological components via these random mutations and natural selection. Joined by special guest Heidi Klumpe, Caltech graduate student and host of the Not My Thesis podcast (https://caltechletters.org/podcasts/not-my-thesis/), we explore cases where mutation gives new function shockingly easily (https://doi.org/10.1038/s41467-018-04026-w), and others where success is harder to come by (https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4476321/). If you are an insect, one change might give you legs where your antenna should be. Heidi, Aditi, John, and Julian discuss how they deal with mistakes in professional settings and the disappointment and stress they can cause. Ever needed advice on how to handle a pipetting robot or the escape of a massive colony of vicious ants? We offer some tips, but mistakes may be a necessary, albeit painful, teacher. Note: this episode was recorded prior to the COVID-19 pandemic, in October of 2019.

  • Biosphere 6: Aggression and Fear

    Biosphere 6: Aggression and Fear
    May 8 2020
    In the current pandemic, many normally harmless activities like grocery shopping are suddenly frightening. But is fear a necessary, or even good, function of our nervous system? Where does it originate from in the brain? Can we directly control emotions like fear, and what consequences would that have for the human experience? Tomás Aquino, a fellow Caltech grad student and neuroscientist friend, joins us this week to discuss these questions and the double-edged role of fear in the graduate school experience. This episode was recorded before the pandemic began, so you will hear us all in a room together, but rest assured that right now we are all social-distancing. We could not have predicted how timely this topic would be or how much graver it is given current events. We wish you all the best and hope that this bit of interesting science gives you something fun to think about during such serious times. For more neuroscience news and research from Tomás Aquino, check out his Twitter: https://twitter.com/the_technetium In the episode we discuss how scientists manipulate aggression through the hypothalamus in mice using an advanced technique called optogenetics. For more details about optogenetics, and viruses like modified rabies that Tomás mentioned, check out this article in Scientific American: https://www.scientificamerican.com/article/optogenetics-controlling/ We also discuss the peculiar case of a patient who does not experience fear in her life due to a missing amygdala (for privacy, the patient’s name is abbreviated as just S.M.) For more on this patient, check out this article in Discover Magazine: https://www.discovermagazine.com/mind/meet-the-woman-without-fear Find us at https://caltechletters.org/podcasts/ Contact us at biospherepodcast@gmail.com Tweet Lev @LMT_spoon Upgoer5 editor: https://splasho.com/upgoer5/ ***Cover image: The Scream by Edvard Munch, one of the most famous artistic depictions of fear.
