Killing in Combat Doesn’t Always Harm Soldiers’ Mental Health

A large study of over 14,000 Norwegian veterans reveals that taking a life in combat doesn't automatically damage a soldier’s mental health—context matters. Veterans from Afghanistan, where combat was expected and rules of engagement were clear, showed no long-term psychological harm from killing.

Pleasure Loss, Not Cravings, Drives Overeating in Obesity

A new study reveals that long-term high-fat diets reduce pleasure from eating by lowering neurotensin, a brain peptide that boosts dopamine response.

Stronger Bonds Before Birth Shape Healthier Mother-Child Futures

A new study reveals that young mothers who feel emotionally connected to their unborn babies are more likely to form healthy, positive relationships with their children later. Researchers tracked 160 racially diverse, low-income mothers from pregnancy to their child’s toddler years, showing that prenatal bonding plays a key role in early childhood development.

Type 2 Diabetes Rewires the Brain Like Early Alzheimer’s

New research reveals that Type 2 diabetes may impair the brain’s reward and memory processing in ways that mirror early Alzheimer’s disease. The study focuses on the anterior cingulate cortex (ACC), a brain region responsible for motivation and emotional regulation, and its interaction with the hippocampus.

How the Brain Learns to Reclassify Danger and Reward

The brain constantly evaluates whether stimuli are positive or negative, prompting approach or avoidance behaviors that are essential for survival. A new study reveals that two neuron types in the nucleus accumbens—D1 and D2 neurons—respond together to both rewarding and aversive stimuli, but in distinct ways.

Exercise Boosts Memory Across All Ages

New research finds that nearly any form of exercise can enhance brain function and memory across the lifespan. This large-scale umbrella review analyzed data from over 258,000 participants and found that low- to moderate-intensity activities like yoga, Tai Chi, and even exergames significantly benefit cognition.

Postpartum Moms Prefer Cooler Temps, Brain Changes Explain Why

Pregnancy and lactation trigger major physiological changes, including shifts in body temperature and environmental preferences. Researchers have now discovered that postpartum female mice develop a long-term preference for cooler environments, driven by brain changes.

ADHD May Raise Dementia Risk

A new study finds that adults with ADHD show brain changes similar to those seen in early-stage dementia, including higher iron accumulation and increased neurofilament light chain (NfL) levels in the blood. Using advanced MRI scans and blood tests, researchers identified elevated iron in key brain regions and signs of nerve damage in ADHD patients compared to healthy individuals.

How Sleep Rewrites the Brain to Strengthen and Optimize Memories

A new study reveals how the brain reprocesses and refines memories during sleep, particularly those related to spatial learning. Researchers tracked rats’ hippocampal neuron activity for up to 20 hours and found that memory patterns first echoed the learning phase and then gradually shifted to match the recollection phase upon waking.

Virtual Reality Reveals Hidden Brain Patterns in Kids With ADHD

Researchers used a virtual reality game and functional MRI to uncover how children's brains with ADHD respond differently during active tasks. Unlike traditional brain scans taken during rest, this immersive approach revealed distinct patterns of neural communication in ADHD, especially in deeper brain structures.

Targeting Brain’s Drainage Pathways Rejuvenates Memory

Rejuvenating the brain's lymphatic vessels can enhance memory in aging mice by improving the removal of waste products from the brain. This research suggests that targeting the meningeal lymphatics—vessels outside the brain—could be a novel approach to treating age-related cognitive decline without directly crossing the blood-brain barrier.

Dendrites Link Memories Formed Close in Time

A new study shows that our brains physically link memories formed close together in time through changes in the dendrites of neurons, rather than in the cell bodies. Using advanced imaging in mice, researchers found that the same dendritic branches are activated when closely timed experiences are encoded, effectively binding the memories.
