Summary: New research shows that extracellular vesicles (EVs)—tiny, membrane-bound particles released by cells—are active and precise messengers during human brain development. These vesicles carry proteins, lipids and transcription factors that can alter recipient cells’ behavior, even influencing nuclear activity and gene expression. The study examined EVs across multiple brain cell types and developmental stages, finding … Read more

A multi-institutional team led by Freda Patterson of the University of Delaware found that … Read more

What makes life worth living? It’s a profound and essential question that stretches across philosophy, psychology, and everyday life. For much of its history, psychology concentrated on mental illness—diagnosing and treating what goes wrong—while paying far less attention to the conditions that allow people and communities to thrive (Seligman, 2011; Kellerman & Seligman, 2023). Positive … Read more

Assertiveness is a skill anyone can learn. Improving it helps us communicate more clearly, relate to others more effectively, and ensure our needs are respected. Increasing assertiveness can be life-changing for people who tend to be shy, passive, or overly accommodating (Hill, 2020). Training reduces the fear around speaking up and supports standing up for … Read more

Summary: A new parent-report questionnaire can help detect signs of autism in children aged 18 to 30 months, though it does not identify every child who will later receive a diagnosis. Source: University of Cambridge New research led by the University of Cambridge shows that the Quantitative Checklist for Autism in Toddlers (Q-CHAT) can identify … Read more

Summary: New Northwestern University research shows that deep, uninterrupted sleep can strengthen memory for faces and names when specific memories are reactivated during slow-wave sleep. Source: Northwestern University Struggling to remember names while faces stay familiar? The solution might be a better nap. A study from Northwestern University provides the first clear evidence that reactivating … Read more

Throughout our lives we pass through many different stages and transitions. As we grow, we often leave the family home, establish our own households, and see our needs shift. Some basic needs remain—shelter, clean water, food—but our emotional and psychological needs evolve. How we understand and respond to those needs strongly shapes our sense of … Read more

Approach developed at UCLA holds promise for 60 percent of patients with the deadly disease. Researchers at the UCLA Eli and Edythe Broad Center of Regenerative Medicine and Stem Cell Research and the Center for Duchenne Muscular Dystrophy at UCLA have developed a stem cell gene‑editing approach that could one day treat a majority of … Read more

Summary: In mice, opioid withdrawal disrupts serotonin signaling to the nucleus accumbens, causing pronounced reductions in sociability and increased social avoidance. Source: Stanford Opioid withdrawal is not only physically painful but also sharply reduces social motivation, a change that undermines recovery by driving isolation at precisely the time when social support is most needed. “Self-isolation … Read more
