The breakthrough discovery enables real-time analysis of nano-light properties with exceptional spatial resolution.
A survey-based study found that exposure to news clips of immigrant deaths decreased white individuals' belief in the American dream, while increasing their views on systemic racism. In contrast, Latinx individuals increased their belief in the American dream and decreased their beliefs in systematic racism.
Scientists create 'μkiss' technique for precise delivery of materials to individual cells, offering new possibilities in single-cell science and next-generation therapeutic applications. The method provides full control over location, time, and scale of material application, enabling detailed studies of cellular processes.
Researchers discovered exceptionally high levels of PFAS in birds and mammals at Holloman Lake, contaminating thousands of species. The study found that even low concentrations of PFAS can cause harm to animals and people, highlighting the need for environmental action.
A study of 1,948 U.S. adults with lifetime suicide attempts found that nearly 20% had no prior psychiatric diagnosis, raising questions about suicide risk screening limits. This finding suggests a broader population is at risk and warrants further investigation into suicidal behavior.
Researchers at University of Alaska Fairbanks have developed a new detection method that can identify landslides within minutes and determine if they pose a tsunami hazard. The method uses seismic data to estimate a landslide's location, volume, and potential impact, with the goal of issuing warnings in under 5 minutes.
