The biology of uncontrolled aggression: How does early-life trauma shape brain circuit function?

Virginia Tech
Grant and Award Announcement

Sora Shin, a neuroscientist at the Fralin Biomedical Research Institute at VTC, received a five-year, $3.2 million grant from the National Institutes of Health to study how early-life trauma alters brain circuits that control aggression and attention. Her research could lead to novel treatment strategies to ease the burden of trauma-related aggression on individuals, families, and communities.

Matches in online dating illuminated in study of Czech app

PLOS
Peer-Reviewed Publication

Per analysis of heterosexual users of a Czech dating app, men tended to pursue women who were more desirable than themselves, but most instances of reciprocated interest occurred between men and women with more similar levels of desirability. Renata Topinkova of the Ludwig Maximilian University of Munich, Germany, and Tomas Diviak of the University of Manchester, U.K., present these findings in the open-access journal PLOS One on July 23, 2025.

California Latino GDP surges past $1 trillion, as Latinos help power state economy

University of California - Los Angeles
Reports and Proceedings

Earlier this year, the latest U.S. Latino GDP Report from UCLA and Cal Lutheran revealed that the direct economic output of the country’s Latino population exceeded $4 trillion for the first time. Now, new findings from the research team that a quarter of that came from Latinos in one state: California. The California Latino GDP Report shows that the state’s Latino GDP surpassed $1 trillion in 2023.

Trajectories of physical activity before and after cardiovascular disease events in CARDIA participants

JAMA Network
Peer-Reviewed Publication

About The Study: In this cohort and nested case-control study among CARDIA (Coronary Artery Risk Development in Young Adults; a prospective study) participants, moderate to vigorous–intensity physical activity (MVPA) declined from early adulthood to midlife then plateaued, with notable demographic differences; cases experienced steep declines before cardiovascular disease (CVD), and gaps compared to controls persisted afterward. Black women had the lowest MVPA across adulthood and the highest risk of low MVPA post-CVD, underscoring the need to support lifelong physical activity and address group differences.

Study of now-submerged migration routes redraws map of how humans settled beyond Africa

University of Kansas
Peer-Reviewed Publication

A University of Kansas researcher recently published a reexamination of ancient human migratory routes from Africa, where homo sapiens first evolved, based on a newly improved glacial isostatic adjustment (GIA) model of historical sea levels along with DNA and archaeological data. An improved simulation of ancient sea levels can reveal how melting glaciers — continuing long after the Last Glacial Maximum — may have transformed migration pathways and shaped the rise of civilizations in Africa.
