On the cover: The octopus uses its long, flexible arms to explore the seafloor for hidden prey. In this issue, van Giesen et al. (594–604) investigate this unique “taste by touch” sense to reveal that the octopus uses specialized chemotactile receptors to detect poorly soluble natural molecules and transmit specific signals among its distributed nervous system. The cover art shows Octopus bimaculoides exploring a coffee cup in its home tank. Image credit: Lena van Giesen....

    When I went on the job market, I tried to refine the list of positions to which I applied by assessing the racial and ethnic make-up of the faculty. This was a wishful exercise because most faculty were white and only a handful had even one Black faculty member. In retrospect, it should have been unsurprising, given that I was used to being the only, or one of a few, starting with my math and science interest in elementary school and persisting throughout my academic and professional career. However, I hope that my presence as a faculty member as well as the recruitment and retention activities I participate in change this experience for prospective Black faculty.

    Diversity is foundational for the fruition of technological advancement and scientific discovery. A diverse body of researchers is essential to tackle STEM in ways we cannot fully explore with a homogeneous workforce. Moreover, the lack of visible representation can often dissuade underrepresented students from pursuing careers in STEM. What sort of messages might someone subconsciously process when they see a homogeneous makeup of classes, scientists featured on presentations, lab personnel, or entire graduate programs?

Commentaries

  • To See a Face Like Mine

    • Esther A. Odekunle
    As an underrepresented scientist navigating her way through the field, I have either noticed or experienced barriers at key stages in the scientific journey that hinder the representation and visibility of diverse people in the community. To see a face like mine represented in science requires intentional action to turn a system not initially built to include all into a community that reflects, embraces, and celebrates people from all demographics.

    We identify problematic areas throughout the Science, Technology, Engineering and Mathematics (STEM) pipeline that perpetuate racial disparities in academia. Distinct ways to curtail these disparities include early exposure and access to resources, supportive mentoring networks and comprehensive training programs specifically for racially minoritized students and trainees at each career stage. These actions will revitalize the STEM pipeline.
  • Revising the a Priori Hypothesis: Systemic Racism Has Penetrated Scientific Funding

    • Kafui Dzirasa
    To manifest our sincerest aspirations to “enhance health, lengthen life, and reduce illness and disability,” the US biomedical research enterprise must directly confront the reality of structural racism in scientific funding and the widespread denial of its existence. I believe that moment in American history has, at long last, arrived. Black Americans have experienced disproportional morbidity and mortality from COVID19, exposing the tawdry underbelly of an American health enterprise that was reared to conceptualize blacks as 3/5ths of a person. Rather than extending Hippocrates’ dearly held promise to first do no harm, our nation’s medical system was seeded with this insidious notion of sub-humanity, facilitating the devaluation of black lives for the potential for scientific and clinical progress. Two centuries later, this persistent bias continues to infect our health care delivery systems. The heinous acts of Dr. J. Marion Sims, who performed gynecological surgical experiments on unanesthetized enslaved women to develop and perfect his clinical procedures, still echo in the unfounded belief that blacks have a higher pain tolerance and the striking incidence of maternal mortality in black women. The unethical Tuskegee study in which medical treatment was withheld from black men to evaluate the course of syphilis still echoes in the reflexive under participation of blacks in clinical trials for potential medical therapeutics.
  • Not All Champions Are Allies in Health Disparities Research

    • Leanne Woods-Burnham
    Responsible health-disparities research requires a multifaceted approach to address genetic, biological, socioeconomic, and lifestyle contributors to disease. For researchers dedicated to the cause, thorough experimental standards at the bench, in the clinic, and within the community must prioritize adequate representation and cultural competency. Not everyone is up for the challenge.
  • Starting Conversations toward Inclusion

    • Faith Karanja,
    • Raegan R. Bostic,
    • Danielle DaCrema,
    • Gustavo G. Pacheco
    Communal discussions on anti-racism and inclusion are crucial to addressing the history of racism in scientific communities. Unfortunately, universities are not universally implementing these conversations. We provide a blueprint for initiating and executing student-led discussions to empower young scientists to take action toward making science more welcoming and inclusive.

Previews

  • A Sucker for Taste

    • Rebecca D. Tarvin
    Biology is entering a new era in which techniques honed in model systems can be applied to the expanding array of organisms with sequenced genomes. In this issue of Cell, van Giesen et al. (2020) characterize the molecular foundation of the touch-taste sensory system in octopus suckers.
  • When Gut Microbiota Creep into Fat, the Fat Creeps Back

    • Sean P. Spencer,
    • Justin L. Sonnenburg
    Ha and colleagues describe a previously unappreciated diversity of microbes in the mesenteric adipose tissue (MAT) surrounding the GI tract. Viable bacteria that are mislocalized from the gut microbiota and metabolically adapted to the MAT contribute to the “creeping fat” of Crohn’s disease.
  • Strength in Numbers: Identifying Neoantigen Targets for Cancer Immunotherapy

    • Rigel J. Kishton,
    • Rachel C. Lynn,
    • Nicholas P. Restifo
    Targeting cancer neoantigens generated by tumor-exclusive somatic mutations is an attractive yet challenging strategy for the robust and specific elimination of tumor cells by cellular immunotherapy. In this issue of Cell, Wells et al. describe a consortium-based approach to optimize bioinformatics pipelines to sensitively and accurately predict immunogenic neoantigens from next-generation sequencing data.

    Ha et al. provide evidence that, in humans with inflammatory bowel disease, the phenomenon known as “creeping fat” is a protective response where mesenteric adipose tissue migrates (or “creeps”) to sites of gut barrier dysfunction to prevent systemic dissemination of potentially harmful bacterial antigens that have translocated across the barrier from the gut lumen.
