Early Autism Traits Show No Sex Differences in Toddlers

A large-scale study of over 2,500 toddlers found no significant clinical differences in autistic traits between males and females at the time of early diagnosis. Conducted over two decades, the study used comprehensive assessments across language, motor skills, cognitive traits, and social behaviors.

Amygdala Shapes Social Choices in Song-Learning Young Birds

Young zebra finches learn their birdsong by observing and imitating adult "tutor" birds, but they don’t follow just anyone. A new study shows that juvenile finches prefer tutors who sing longer but less often, suggesting social cues guide their choices.

Nitrous Oxide Unlocks Blood-Brain Barrier for Safer Gene Delivery

Researchers have discovered that nitrous oxide can safely enhance the delivery of gene therapy to the brain by making the blood-brain barrier (BBB) more permeable when paired with focused ultrasound (FUS). This method required significantly lower concentrations of microbubbles and ultrasound pressure than conventional techniques, reducing the risk of tissue damage.

Daylight Boosts Immune Defense

Researchers have discovered that daylight enhances the infection-fighting power of neutrophils, the most abundant white blood cells in the body. Using transparent zebrafish, scientists observed that these immune cells contain internal circadian clocks that are activated by light, boosting their bacterial-killing ability during the day.

Brainstem Neurons Hold Key to Semaglutide’s Weight Loss Effects

Researchers have identified a specific group of brainstem neurons that mediate the appetite-reducing and weight-loss effects of semaglutide without triggering side effects like nausea. In mice, activating these neurons led to reduced food intake and fat loss, mimicking the drug’s benefits.

The Nature of Nostalgia: How Time Transforms Emotion in Memory

New research reveals that nostalgic memories don’t remain emotionally static, they evolve over time. While these memories are typically rich in positive feelings at the time they occur, those feelings tend to fade, making space for rising negative emotions like regret and loneliness.

Boredom Is Good for You: Why Embracing It Calms the Brain

Boredom, often seen as a negative state to avoid, may actually serve an important role in emotional regulation and brain health. When we're bored, the brain shifts away from external attention networks and activates introspective systems like the default mode network, encouraging creativity and self-reflection.

Chronic Stress Quietly Raises Your Stroke Risk

Chronic stress is increasingly recognized as a contributor to stroke risk by intensifying conditions like high blood pressure, inflammation, and unhealthy lifestyle habits. While stress isn't as easily measured as cholesterol or blood pressure, long-term exposure to it can set the stage for vascular damage and increase both ischemic and, less commonly, hemorrhagic stroke risk.

Dementia Diagnoses Decline, But More Are Living Longer With the Disease

A new study of over 25 million Medicare recipients found that while dementia incidence in the U.S. is declining, more older adults are living longer with the condition. From 2015 to 2021, new diagnoses dropped from 3.5% to 2.8%, yet prevalence increased to nearly 12%.

ALS Drug Shows Unprecedented Recovery in Patients With Rare Mutation

A groundbreaking experimental therapy for a rare, aggressive form of ALS caused by FUS gene mutations has produced surprising clinical improvements in some patients, including restored mobility and extended survival. The treatment uses antisense technology to silence the FUS gene, reducing toxic protein buildup in motor neurons. Two patients in a recent case series showed remarkable responses—one regained the ability to walk and breathe unassisted, while another has remained symptom-free for three years.

Stress Hampers Emotional Regulation in Anxiety, Depression & BPD

New research reveals that acute stress can impair key brain functions involved in emotion regulation, particularly in individuals with distress-related disorders like depression, anxiety, and borderline personality disorder. The study found that executive functions—such as working memory, impulse control, and cognitive flexibility—are more likely to be disrupted in these individuals during high-stress moments.

Placebo Triggers Brain’s Opioid System to Relieve Pain

Researchers have successfully induced the placebo effect in rats, uncovering the neural mechanisms behind how belief in pain relief can reduce the perception of pain. Using conditioning, rats learned to associate injections with pain relief, and later exhibited reduced pain responses even when injected with saline.
