Political comment sections can get ugly fast. New research suggests that subtle wording in the original post, such as broad claims about what “Democrats want,” is linked to how much partisan prejudice shows up in the replies. dlvr.​it/TW66TJ

People treated with ketamine or MDMA showed changes in chemical tags on genes related to brain plasticity, a small study found. The two drugs converged on similar biological pathways while affecting largely different genes. dlvr.​it/TW647P

Childhood maltreatment comes in many forms, and a new brain imaging study suggests those forms aren’t interchangeable. Physical abuse and emotional abuse were tied to different structural brain patterns in young adults seeking mental health help. dlvr.​it/TW623m

Psychology’s replication problems drew wide attention after 2015. A new study in Nature suggests the challenge is not unique to psychology: across economics, education, business, sociology, and political science, success rates were similar. dlvr.​it/TW5zv4

Beauty has long been described as something that makes us pause and look. Neuroscientists in Italy tested that idea by recording brain activity while people viewed nature photos, and found signs that liked images dampened movement preparation. dlvr.​it/TW5k52

With a mirror and some well-timed brushstrokes, researchers gave volunteers the sensation of a sixth finger. Afterward, people judged that their hand needed a wider opening to fit through and could grasp larger blocks. dlvr.​it/TW5RDH

People with higher intelligence scores tend to have slightly smaller families in American and British surveys. But when researchers wait until people finish having children and compare brothers from the same families, the link shrinks or even reverses. dlvr.​it/TW5NzL

A large study reveals that adolescents who experience a warm relationship with a mother figure and limit their sedentary screen time are more likely to demonstrate resilience in adulthood following childhood abuse. dlvr.​it/TW5LVS

Sex out of obligation is often treated as a red flag in relationships. But a new study suggests it may serve a purpose for some people, appearing most often when they sense their relationship could be under threat. dlvr.​it/TW5JKp

Fear tends to involve possible danger ahead, while horror often follows learning about something that shouldn’t happen. A new study suggests that graphic, extreme descriptions of harm push readers toward horror by making events feel abnormal. dlvr.​it/TW5G5p

Tomatoes are the main dietary source of lycopene, a red pigment that can reach the brain. In a new trial, daily tomato paste was linked to better attention and memory scores, along with preliminary changes in how certain brain networks communicate. dlvr.​it/TW4wvP

A disorganized home is often linked to poor academic performance, but a large twin study reveals that shared genetics and broader family environments are to blame, not the noise and clutter itself. dlvr.​it/TW4s6G
