A Brief History of Clinical Electrocardiography: A Century After Einthoven's Nobel Prize.

The invention of the string galvanometer by Willem Einthoven in 1901 ushered in a new era of clinical investigation. Previous instruments were capable only of rudimentary measurements that were of limited utility. Advances in physiology and engineering allowed Einthoven to construct a device that was uniquely capable of recording the minute electrical currents of the heart.

Pursuing healthy homeownership: an evaluation of the neighborhood health trajectories of shared equity homeowners.

Background: Shared equity homeownership - a model in which low- and moderate-income households purchase homes at affordable prices on the condition that the houses remain affordable upon resale - has been shown to produce several health-enhancing housing outcomes. These include permanent affordability, housing stability, and modest wealth-building. However, studies suggest low- and moderate-income households may sacrifice neighborhood quality when becoming homeowners, which can undermine the health benefits of homeownership.

Tenant Right-to-Counsel and Adverse Birth Outcomes in New York, New York.

Importance: In 2017, New York, New York, launched the United States' first right-to-counsel program, guaranteeing lawyers to low-income tenants in select zip codes, which was associated with reducing eviction risk by half. Given documented associations between evictions during pregnancy and adverse birth outcomes, the right-to-counsel program may be associated with improved birth outcomes.

Objective: To measure associations between zip code-level right-to-counsel access and risk of adverse birth outcomes, including preterm birth and low birth weight, among infants born to Medicaid-insured birthing parents.

Attraction to politically extreme users on social media.

Political segregation is a pressing issue, particularly on social media platforms. Recent research suggests that one driver of segregation is -people's preference for others in their political group who have more extreme (rather than more moderate) political views. However, acrophily has been found in lab experiments, where people choose to interact with others based on little information.

Attraction by pairwise coherence explains the emergence of ideological sorting.

Political polarization has become a growing concern in democratic societies, as it drives tribal alignments and erodes civic deliberation among citizens. Given its prevalence across different countries, previous research has sought to understand under which conditions people tend to endorse extreme opinions. However, in polarized contexts, citizens not only adopt more extreme views but also become correlated across issues that are, a priori, seemingly unrelated.
