Interdisciplinary approaches are fundamental to decode the biology of adversity.

The COVID-19 pandemic has highlighted structural inequalities and racism promoting health disparities among communities of color. Taking cardiovascular disease as an example, we provide a framework for multidisciplinary efforts leveraging translational and epidemiologic approaches to decode the biological impacts of inequalities and racism and develop targeted interventions that promote health equity.

To See a Face Like Mine.

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.

Starting Conversations toward Inclusion.

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.

Revising the a Priori Hypothesis: Systemic Racism Has Penetrated Scientific Funding.

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.

Not All Champions Are Allies in Health Disparities Research.

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.

Race Matters.

Despite their initial high interest in science, students who belong to excluded racial and ethnic groups leave science at unacceptably high rates. "Fixing the student" approaches are not sufficient at stemming the loss. It is time to change the culture of science by putting inclusive diversity at the center.

Voices on Diversity: Combating Racial Inequality to Increase Diversity.

As part of our commitment to amplifying the voices of underrepresented scientists, we are publishing the insights and experiences of a panel of underrepresented scientists in a series of questions and answers. Here, they discuss ways that the scientific community can combat racial inequality and increase diversity. These are the personal opinions of the authors and may not reflect the views of their institutions.

Black in Cancer: An interview with founders Sigourney Bell and Henry J. Henderson.

We talk to Sigourney Bell and Henry J. Henderson about what motivated them to found Black in Cancer, the importance of community and representation, as well as the resources the organization provides, future directions, and how we and our readers can provide support.

Social capital I: measurement and associations with economic mobility.

Social capital-the strength of an individual's social network and community-has been identified as a potential determinant of outcomes ranging from education to health1-8. However, efforts to understand what types of social capital matter for these outcomes have been hindered by a lack of social network data. Here, in the first of a pair of papers9, we use data on 21 billion friendships from Facebook to study social capital. We measure and analyse three types of social capital by ZIP (postal) code in the United States: (1) connectedness between different types of people, such as those with low versus high socioeconomic status (SES); (2) social cohesion, such as the extent of cliques in friendship networks; and (3) civic engagement, such as rates of volunteering. These measures vary substantially across areas, but are not highly correlated with each other. We demonstrate the importance of distinguishing these forms of social capital by analysing their associations with economic mobility across areas. The share of high-SES friends among individuals with low SES-which we term economic connectedness-is among the strongest predictors of upward income mobility identified to date10,11. Other social capital measures are not strongly associated with economic mobility. If children with low-SES parents were to grow up in counties with economic connectedness comparable to that of the average child with high-SES parents, their incomes in adulthood would increase by 20% on average. Differences in economic connectedness can explain well-known relationships between upward income mobility and racial segregation, poverty rates, and inequality12-14. To support further research and policy interventions, we publicly release privacy-protected statistics on social capital by ZIP code at https://www.socialcapital.org .

The Black Lives Matter movement mitigates bias against racial minority actors.

Watching movies is among the most popular entertainment and cultural activities. How do viewers react when a movie sequel increases racial minority actors in the main cast ("minority increase")? On the one hand, such sequels may receive better evaluations if viewers appreciate racially inclusive casting for its novel elements (the value-in-diversity perspective) and moral appeal (the fairness perspective on diversity). On the other hand, discrimination research suggests that if viewers harbor biases against racial minorities, sequels with minority increase may receive worse evaluations. To examine these competing possibilities, we analyze a unique panel dataset of movie series released from 1998 to 2021 and conduct text analysis of 312,457 reviews of these movies. Consistent with discrimination research, we find that movies with minority increase receive lower ratings and more toxic reviews. Importantly, these effects weaken after the advent of the Black Lives Matter (BLM) movement, especially when the movement's intensity is high. These results are reliable across various robustness checks (e.g., propensity score matching, random implementation test). We conceptually replicate the bias mitigation effect of BLM in a preregistered experiment: Heightening the salience of BLM increases White individuals' acceptance of racial minority increase in a movie sequel. This research demonstrates the power of social movements in fostering diversity, equality, and inclusion.

Antiracism and positive intergenerational (infant) outcomes: A county-level examination of low birth weight and infant mortality.

Racism is associated with negative intergenerational (infant) outcomes. That is, racism, both perceived and structural, is linked to critical, immediate, and long-term health factors such as low birth weight and infant mortality. Antiracism-resistance to racism such as support for the Black Lives Matter (BLM) movement-has been linked to positive emotional, subjective, and mental health outcomes among adults and adolescents. To theoretically build on and integrate such past findings, the present research asked whether such advantageous health correlations might extend intergenerationally to infant outcomes? It examined a theoretical/correlational process model in which mental and physical health indicators might be indirectly related to associations between antiracism and infant health outcomes. Analyses assessed county-level data that measured BLM support (indexed as volume of BLM marches) and infant outcomes from 2014 to 2020. As predicted, in the tested model, BLM support was negatively correlated with 1) low birth weight (Ncounties = 1,445) and 2) mortalities (Ncounties = 409) among African American infants. Given salient, intergroup, policy debates tied to antiracism, the present research also examined associations among White Americans. In the tested model, BLM marches were not meaningfully related to rates of low birth weight among White American infants (Ncounties = 2,930). However, BLM support was negatively related to mortalities among White American infants (Ncounties = 862). Analyses controlled for structural indicators of income inequality, implicit/explicit bias, voting behavior, prior low birth weight/infant mortality rates, and demographic characteristics. Theory/applied implications of antiracism being linked to nonnegative and positive infant health associations tied to both marginalized and dominant social groups are discussed.
