L is Smooth, R is Rough: Our Brains Link Sounds to Sensations

A new study reveals a near-universal association between the trilled R sound and rough textures or jagged shapes, while the L sound aligns with smooth textures or straight lines. Researchers tested over 1,000 participants speaking 28 languages and found that 94% matched the trilled R to jagged lines and 84% matched L to smooth lines, even among speakers of languages without a trilled R.

Chimpanzees Show Friendly Behaviors Are Contagious

Grooming and play behaviors in chimpanzees are contagious, fostering social bonds and harmony within their groups. Conducted at a wildlife orphanage, the research shows how observing others’ positive actions encourages similar behaviors, with grooming occurring more often among close partners and play thriving among younger chimps.

Mapping Memory: Unveiling Molecular Signals in the Hippocampus

A recent study uncovers molecular mechanisms driving memory formation in the hippocampus, focusing on mossy fiber synapses. Researchers observed key proteins, Cav2.1 and Munc13, rearrange during memory processing, enhancing synapse precision and power.

Neurology News Articles

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

AI Improves Brain Tumor Detection

AI models trained on MRI data can now distinguish brain tumors from healthy tissue with high accuracy, nearing human performance. Using convolutional neural networks and transfer learning from tasks like camouflage detection, researchers improved the models’ ability to recognize tumors.

Earpiece Tech Detects Early Alzheimer’s Through Eye Movement Signals

Researchers are exploring how earpiece microphones, or "hearables," could detect early signs of Alzheimer’s disease by monitoring subtle eye movement changes. Alzheimer’s impacts motor and cognitive functions, with slowed or delayed eye movements (saccades) being an early indicator.

Early-Onset Diabetes Linked to Increased Dementia Risk

New research reveals that individuals diagnosed with type 2 diabetes at a younger age face a higher risk of developing dementia, particularly those with obesity. The study found that for each year earlier type 2 diabetes is diagnosed, dementia risk increases by 1.9%.

AI News Articles

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

Human Cell Atlas Transforms Understanding of Disease

The Human Cell Atlas (HCA) consortium has published over 40 studies revealing groundbreaking insights into human biology through large-scale mapping of cells. These studies cover diverse areas such as brain development, gut inflammation, and COVID-19 lung responses, while also showcasing the power of AI in understanding cellular mechanisms.

How AI Could Shape Human Evolution in Subtle Yet Profound Ways

Artificial intelligence is becoming a pivotal force in human lives, prompting questions about its evolutionary effects. A new study explores how AI may influence human evolution through everyday interactions, likening human-AI dynamics to ecological relationships such as predation or competition. Potential evolutionary shifts include changes in brain size, attention spans, personality traits, and social behaviors, particularly through AI's impact on relationships and decision-making.

AI Outpaces Humans in Rapid Disease Detection

A deep learning AI model developed by researchers significantly accelerates the detection of pathology in animal and human tissue images, surpassing human accuracy in some cases. This AI, trained on high-resolution images from past studies, quickly identifies signs of diseases like cancer that typically take hours for pathologists to detect.

Psychology News Articles

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

War Impacts Child Development, Alters DNA

War exposure in Syrian refugee children triggered unique DNA methylation changes, marking genes involved in brain development and stress responses. These epigenetic changes suggest potential long-term effects on health and development, distinct from other traumas like poverty.

How Podcasts Inspire Positive Healthy Changes

Podcasts are increasingly popular, with people spending over five hours weekly listening to them. A new study reveals health-related podcasts can significantly improve health knowledge, boost physical activity, and encourage healthier eating habits.

Leveling Up: How Gaming Boosts Decision Making and Cooperation

A new study reveals that multiplayer online gaming can enhance workplace skills such as teamwork, problem-solving, and leadership. Researchers found that gamers with years of experience apply their in-game behaviors to professional settings, developing patience, self-confidence, and coaching abilities.

NMDA Stabilizes Brain Activity

Researchers have discovered that the NMDA receptor (NMDAR), known for its role in learning and memory, also stabilizes brain activity by setting baseline neural network activity. This stabilization supports the brain’s adaptability amid constant environmental and physiological changes.

Toddlers Learn Best After Experiencing Impossible Events

Young children grasp possibilities and distinctions between improbable and impossible events well before they can explain them in words. In a new study, two- and three-year-olds were found to learn more effectively after witnessing impossible events, which seem to trigger an intense curiosity.

Cannabis Use Linked to Epigenetic Changes, Cancer Risk

Research indicates that cannabis use causes cellular damage that increases the risk of highly cancerous tumors by disrupting mitochondria and damaging DNA. This genotoxicity can result in mutations, accelerated aging, and birth defects, with potential to be passed on to future generations through egg and sperm. Insights from broader mitochondrial research provide a mechanistic understanding of how cannabis affects genetic stability.

Exercise Spurs Nerve Growth Through Biochemical and Physical Impact

Researchers found that exercise promotes neuron growth through both biochemical signals (myokines) and physical stretching. Muscle cells, when contracted, release myokines that boost neuron growth and maturity.

Menopausal Hormone Therapy’s Effects on Brain Health

Menopausal hormone therapy (MHT) has nuanced effects on brain health, influenced by factors like age, treatment duration, and past surgical history. The study found that current MHT users had higher brain age gaps and smaller hippocampal volumes, while past users showed no significant differences compared to non-users.
