How nostalgic music helps minds remember

A new study from USC Dornsife's Brain and Creativity Institute found that nostalgic music engages the brain's default mode network linked to memory and self-reflection, as well as its reward circuitry. This discovery could support emotional well-being and cognitive function in individuals with memory impairments.

How changing L.A.’s tree rules could cool more neighborhoods

A new study suggests that easing L.A.'s outdated tree planting rules could significantly grow the city's urban tree canopy without compromising safety. By relaxing restrictions near intersections, utility poles, gas lines, and other infrastructure, tree coverage in lower-income neighborhoods like Boyle Heights could increase by up to 26%.

While most Americans strongly support civics education in schools, partisan divide on DEI policies and free speech on college campuses remains

A new USC report reveals that most Americans support civics education in schools, with high levels of bipartisan agreement on issues like teaching about racism and promoting critical thinking. However, sharp partisan divisions persist on issues like diversity, equity, and inclusion policies and student free speech on college campuses.

Scientists unlock clues to new treatments for muscular dystrophy

Researchers at USC Dornsife College of Letters, Arts and Sciences have made a breakthrough discovery about how tiny protein clusters form in cells. These nanoclusters play a crucial role in mechanotransduction, a process that fails in people with Emery-Dreifuss muscular dystrophy, leading to muscle weakness and heart problems.

Despite high employment rates, Black immigrants in the United States more likely to be uninsured, USC study shows

A recent USC study found that Black immigrants in the United States have a 9% higher likelihood of being uninsured compared to U.S.-born white adults, despite having a 70.2% employment rate. The disparity is attributed to wage penalties and systemic barriers related to race and immigration status.

Who carries and uses Naloxone in the U.S.?

A new study provides the first nationwide picture of who knows about, carries, and uses naloxone to reverse deadly opioid overdoses. The survey found that people's perception of overdose risk correlates with their decision to carry naloxone, and those with high-risk profiles are more likely to carry the drug.

Long before the L.A. fires, America’s housing crisis displaced millions

A new USC study reveals that the US is facing a shortage of 4.5 million homes due to policy missteps in the early 2000s, which led to a historic housing bubble and subsequent Great Recession. The crisis has disproportionately affected millennials and people of color, with racial and ethnic disparities in homeownership widening over time.

How one state’s repeal of a prison ‘pay-to-stay’ law could guide national reform

A new study by USC Dornsife researchers reveals how Illinois' repeal of the 'pay-to-stay' law, charging inmates for room and board, can inform national reform efforts. The study found that lawmakers used a pragmatic approach to reform, highlighting the importance of data-driven decision making in advancing criminal justice reform.

Most Medicare beneficiaries do not compare prescription drug plans – and may be sticking with bad plans

A USC Schaeffer study found that over half of Medicare beneficiaries with stand-alone Part D plans did not switch due to lack of plan comparisons, with many unaware of how to change plans or missing out on better coverage options. This complacency allows insurers to exploit beneficiaries' inattention and boost profits.

The Salton Sea — an area rich with lithium — is a hot spot for child respiratory issues

A USC study found that children living closest to the Salton Sea experience more respiratory issues due to airborne dust, triggering asthma, coughing, and disrupted sleep. The study also suggests that dust events have a greater impact on wheezing and sleep disturbances among children in these areas.

Exposure to particular sources of air pollution is harmful to children’s learning and memory, a USC study shows

A USC study involving 8,500 children found that exposure to certain sources of air pollution, particularly ammonium nitrate, is linked to poor learning and memory performance in 9- and 10-year-olds. This study contributes to the mounting evidence that fine particulate matter PM2.5 can cause neurocognitive harm across the lifespan.
