Oxytocin May Treat the Social Deficits of Psychopathy

Psychopathy impairs the ability to recognize and respond appropriately to emotional facial expressions, often disrupting empathy and social behavior. A new review explores whether oxytocin—a neuropeptide known to promote social bonding—can help compensate for these deficits.

How the Brain Reactivates Emotional Experiences

A new study using direct recordings from human brains reveals how the amygdala and hippocampus coordinate to form and retrieve emotional memories. During aversive memory encoding, high-frequency gamma activity in the amygdala shapes hippocampal responses, which are later reactivated in the hippocampus—but not the amygdala—during memory recall.

Inflammation Influences Cannabis’s Effects on Anxiety and Sleep

A new study shows that inflammation levels influence how cannabis affects anxiety and sleep quality. Researchers found no overall change in inflammatory markers after 4 weeks of cannabis use, but baseline inflammation moderated outcomes.

Synaptic Tau and Astrocytes Drive PSP Progression

ew research uncovers how tau pathology spreads and damages synapses in progressive supranuclear palsy (PSP). Using human postmortem tissue and live brain slice models, scientists showed tau accumulates in both pre- and postsynaptic terminals, likely propagating neuron-to-neuron.

Hunger Sharpens Sleep Rhythms That Solidify Memories

New research shows that the brain’s slow oscillations and sleep spindles — key rhythms that consolidate memories during sleep — can be shaped by more than just age. While these rhythms have long been thought of as stable traits, studies reveal that metabolic state, like fasting before sleep, can enhance their timing and co-occurrence.

Why the Psychopathic Brain Struggles With Emotion and Control

New research reveals how structural brain connectivity shapes psychopathic traits and externalizing behaviors. Using advanced connectome modeling, scientists identified two key networks: one tied to impaired emotional processing, the other to poor attentional control.

Pregnancy Stress Disrupts Baby’s Microbiome, Increasing Depression Risk

Prenatal stress in mothers can leave a lasting imprint on their offspring, predisposing them to depression-like behaviors. Researchers found that maternal stress disrupts the gut microbiome and metabolite production, which are vertically transmitted to the young.

FoMO and Dark Personalities Drive Online Political Engagement

A large cross-national study examined how psychopathy, narcissism, fear of missing out (FoMO), and cognitive ability influence online political participation. Across eight countries, people high in psychopathy and FoMO consistently engaged more in digital political activities, while narcissism predicted participation only in some contexts.

Youthful Blood Restores Aging Retina and Vision

Researchers demonstrated that systemic factors from young mice can rejuvenate the aging retina by alleviating cellular senescence and restoring function. Using heterochronic parabiosis and single-cell RNA sequencing, the study identified AdipoR1 and its downstream AMPK signaling as key drivers of retinal rejuvenation.

Study Reveals Biological Bias in Baby Boy or Girl Odds

A massive study of over 58,000 women shows that families may have their own subtle biological bias toward having boys or girls, rather than offspring sex being purely random. Researchers found that older maternal age at first birth and specific maternal genetic variants were linked to having only sons or only daughters.

Genetic Link Between Cannabis Use Disorder and Mental Health

A large genetic study reveals that cannabis use disorder (CanUD) is strongly linked to increased risk for multiple psychiatric disorders, including depression, PTSD, ADHD, and schizophrenia. By analyzing global and local genetic correlations, colocalization, Mendelian randomization, and structural equation modeling, researchers showed CanUD has distinct genetic signatures compared to casual cannabis use.

More Than Serotonin: How Psychedelics Engage the Whole Brain

Classical psychedelics like LSD, psilocybin, and mescaline are known for activating the 5-HT2A serotonin receptor, but a new study reveals their effects go far beyond. Researchers profiled 41 psychedelics against over 300 human receptors and found potent activity at serotonin, dopamine, and adrenergic sites.
