Tiny Cells Shape Memory, Mood, and Behavior

Scientists have uncovered a biological “blueprint” that shows how the brain’s smallest building blocks create the large networks that drive thought, emotion, and behavior. By combining brain imaging with genetic and molecular data, the team demonstrated that cellular and chemical patterns directly shape functional brain networks.

Supplement Mix Reverses Autism Traits

Researchers have made a major advance, discovering that a low-dose mixture of zinc, serine, and branch-chain amino acids (BCAAs) can successfully alleviate behavioral symptoms in three different mouse models of autism. This breakthrough lies in the synergy of the three common nutrients, which work together to restore normal neural communication and reduce hyperactivity in the brain's emotional center.

Genes Behind Dog Behaviors Also Shape Human Emotions

Researchers analyzed the genomes and behavioral profiles of 1,300 golden retrievers and found that several behavioral traits—such as trainability, fear of strangers, and aggression toward other dogs—are shaped by specific genetic variants. Remarkably, a dozen of these same genes also influence emotional and cognitive traits in humans, revealing shared biological roots across species.

Unexpected Superhero Cameos Make People Kinder

A new behavioral study demonstrates that sudden, unexpected events can significantly increase altruistic behavior in everyday environments. When a person dressed as Batman appeared on a Milan subway, passengers were nearly twice as likely to give up their seats to a pregnant woman compared to the normal routine condition.

Moving Away Makes Faces Seem Angrier

New research shows that our own physical movements can alter how we perceive emotions on others’ faces. In a virtual reality experiment, participants were more likely to judge a face as angry when they actively moved away from it, compared to when the face moved away from them.

Gut Microbes May Shape Brain and Behavior Through Hidden Mutations

In a groundbreaking study using Merino sheep, researchers uncovered that tiny genetic variations within gut microbes can influence brain-related behavior. By sequencing over 5,000 microbial genomes—including 3,500 never before reported—they linked single nucleotide variations (SNVs) in microbes to neurobehavioral traits and plasma metabolites tied to brain function.

Prenatal Endocannabinoid Disruption Impacts Brain Wiring, Behavior

A new study shows that prenatal disruption of the endocannabinoid system can have long-lasting effects on brain structure and behavior. When scientists lowered the activity of an endocannabinoid receptor in the developing mouse brain, neurons failed to migrate properly, and key genes involved in brain development were altered.

When Machines Become Our Moral Loophole

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.

Loneliness Drives Teens to Seek Rewards

A new study reveals that adolescents are highly sensitive to even brief periods of social isolation, showing a sharp increase in motivation to seek rewards after just a few hours alone. This heightened drive can encourage reconnection but may also lead to risky behaviors if social contact isn’t available.

Aggression Is Contagious: Observing Violence Primes the Brain for Aggression

A new study shows that observing violence can make individuals more likely to act aggressively later, but the effect depends on familiarity. Male mice who watched familiar peers attack others became more violent afterward, driven by amygdala neurons that “prime” aggression.

Environment Shapes Autism-Linked Social Behaviors

A new study shows that environment significantly affects social behavior in zebrafish carrying a mutation linked to autism. In stressful, white Styrofoam tanks, the fish displayed higher anxiety and less social contact, while in familiar Plexiglass tanks their sociability improved.

Autism Gene Found to Alter Brain’s Social Hormone Signals

A new study reveals how a mutation in the Shank3 gene, associated with autism, alters social behavior by disrupting vasopressin release in the brain. In mice, this mutation reduced sociability and defensive aggression by limiting vasopressin reaching the lateral septum.
