A new study shows that fluoxetine, better known as Prozac, does more than increase serotonin—it changes how brain cells handle energy and rebuild connections. After two weeks of treatment, parvalbumin interneurons in the prefrontal cortex became less rigid, with mitochondrial energy genes reduced and plasticity genes upregulated.
A large Swedish study of 1.8 million pregnancies found that mental ill health around pregnancy has risen in recent years, with risks spiking after childbirth. While depression and psychosis rates drop during pregnancy, postpartum depression is 20% more likely within weeks 5–15, and psychosis risk is up to seven times higher in the first 20 weeks.
A new study shows that sugary drinks don’t just affect physical health—they may also raise the risk of depression in women by disrupting the gut microbiome. Researchers found that high consumption of soft drinks was linked to both a greater likelihood of major depressive disorder and more severe symptoms, particularly among women.
A new study reveals that recalling positive memories before stepping on stage can significantly boost musicians’ performance. Professional wind instrumentalists who reflected on positive experiences showed higher nervous system activity, greater emotional positivity, and stronger arousal compared to those recalling negative or no memories.
For the first time, lab-grown mini brains have revealed how neurons misfire in schizophrenia and bipolar disorder. Using machine learning to analyze electrical activity, researchers identified distinct firing patterns that served as biomarkers, distinguishing patient-derived organoids from healthy ones with over 90% accuracy.
A new study shows that both mothers and fathers significantly shape their adolescent children’s social anxiety, but in different ways. Warmth, affection, and acceptance from either parent reduce anxiety, while rejection, coldness, and controlling behaviors heighten it.
A new study demonstrates that some highly gifted dogs can categorize objects not just by appearance, but by how they are used. When taught words like “pull” or “fetch,” these dogs later applied the concepts to brand-new toys through natural play, without training or explicit labeling.
A new study shows that fetal movement frequency in late pregnancy is directly tied to stronger maternal-fetal attachment. Using an actocardiograph, researchers objectively measured movements and found that higher activity was associated with greater emotional bonding, even when controlling for other factors like maternal mood or gestational age.
A large study across 13 experiments with over 8,000 participants shows that people are far more likely to act dishonestly when they can delegate tasks to AI rather than do them themselves. Dishonesty rose most when participants only had to set broad goals, rather than explicit instructions, allowing them to distance themselves from the unethical act.
