Researchers developed the first comprehensive brain map showing activity in prairie voles during mating and bonding, uncovering 68 brain regions involved in forming enduring monogamous relationships. This study challenges previous assumptions that male and female brains operate differently during these processes, revealing nearly identical patterns of brain activity in both sexes.
Researchers unveiled significant findings on the production of 11-cis-retinal, a molecule crucial for vision in both humans and insects. By studying the NinaB protein in insects and comparing it to the human RPE65 protein, both essential for synthesizing 11-cis-retinal, the team discovered key differences in their operational mechanisms despite their structural similarities.
Children living in violent neighborhoods exhibit increased amygdala reactivity, signaling heightened sensitivity to threats, which can affect mental health and socioemotional functioning. However, nurturing parenting can protect against these adverse effects, reducing exposure to community violence and its impact on the brain.

Neurology news articles cover neurology, brain cancer, traumatic brain injuries, neurosurgery, neuroanatomy, brain research and neurological disorders.

Researchers uncovered how stress can significantly increase cancer metastasis through the activation of white blood cells known as neutrophils, which create web-like structures promoting cancer spread. By simulating chronic stress in mice, the team observed a dramatic increase in metastatic lesions, linking stress hormones to the formation of neutrophil extracellular traps (NETs) that foster a metastasis-friendly environment.
Researchers made a groundbreaking discovery in the study of Long COVID, identifying that the integrity of blood vessels in the brain is compromised in patients experiencing brain fog and cognitive decline. The study utilized a novel MRI technique to reveal "leakiness" in the brain's blood vessels, providing an objective method to distinguish patients with neurological symptoms of Long COVID.
Researchers have developed an AI method that can predict Alzheimer's Disease up to seven years before the onset of symptoms, utilizing machine learning to analyze patient records. Their study highlights high cholesterol and osteoporosis—particularly in women—as key predictors, showcasing AI's potential to unveil complex disease patterns and biological drivers.

AI news articles cover science articles about artificial intelligence including ChatGPT, Bard, Dalle, neural networks, machine learning, LLMs, AGI and other AI related topics.

Researchers developed an artificial intelligence model that accurately determines the sex of individuals based on brain scans, with over 90% success. This breakthrough supports the theory that significant sex differences in brain organization exist, challenging long-standing controversies.
Researchers developed an innovative AI tool, DeepGO-SE, that excels in predicting the functions of unknown proteins, marking a significant advance in bioinformatics. Leveraging large language models and logical entailment, this tool can deduce molecular functions even for proteins without existing database matches, offering a groundbreaking approach to understanding cellular mechanisms.
Dr. Roman V. Yampolskiy, an AI Safety expert, warns of the unprecedented risks associated with artificial intelligence in his forthcoming book, AI: Unexplainable, Unpredictable, Uncontrollable. Through an extensive review, Yampolskiy reveals a lack of evidence proving AI can be safely controlled, pointing out the potential for AI to cause existential catastrophes.

Science research articles cover psychology, depression, mental health, schizophrenia, mental disorders, happiness, stress, PTSD, autism, psychiatry and therapy.

Genetic factors account for approximately 33% of the variation in trust levels between individuals, highlighting the heritable nature of this crucial social trait. The research utilized data from twins and a comprehensive analysis of previous studies to explore the genetic and environmental influences on trust.
Researchers discovered that a brief, electrically induced smile can make neutral faces seem happier, a revelation that holds promise for understanding emotional perception and potentially treating affective disorders. The study utilized facial electrical stimulation, a technique inspired by Charles Darwin's work, to produce quick, involuntary smiles in participants.
A new study highlights the critical link between sleep, circadian rhythms, and psychiatric disorders, suggesting that disturbances in sleep and internal body clocks can trigger or exacerbate mental health issues. The research underscores the prevalence of sleep-circadian disturbances across all psychiatric disorders, pointing to the need for holistic treatments that address these factors.

A new study reveals that adolescent girls who ruminate show distinct brain activity patterns when facing social rejection. Using fMRI scans, the research demonstrates increased activity in brain areas related to self-concept and emotional states in girls prone to rumination.
Researchers developed the world's first 3D-printed brain tissue that grows and behaves similarly to natural brain tissue, marking a significant leap forward for neurological and neurodevelopmental disorder research. This novel 3D-printing technique uses a horizontal layering approach and a softer bio-ink, allowing neurons to interconnect and form networks akin to human brain structures.
Researchers achieved a significant advancement in robotics by replicating human-like variable speed walking using a musculoskeletal model. This model, steered by a reflex control method akin to the human nervous system, enhances our understanding of human locomotion and sets new standards for robotic technology.
Researchers have discovered a molecular complex crucial for the transport of mitochondria within neurons, offering new insights into preventing neurodegenerative diseases. The complex, identified as Alex3/Gαq, is pivotal for distributing energy-producing mitochondria throughout neurons, essential for neurotransmission and neuronal functions.
