Pregnancy Reshapes Mom’s Brain, Reducing Gray Matter

Pregnancy leads to a 4.9% reduction in gray matter volume in 94% of the brain, with partial recovery postpartum, primarily in regions tied to social cognition. A groundbreaking neuroimaging study analyzed brain changes in 179 women, including non-gestational mothers, revealing that these changes are biologically driven by pregnancy hormones rather than the experience of motherhood.

Upper Body Strength Predicts Sexual Partner Count in Men and Women

A study revealed that both men and women with greater upper body strength report more lifetime sexual partners, challenging the sexual selection hypothesis, which emphasizes male physical competition for mates. While men’s strength is often linked to evolutionary advantages like hunting and mate competition, the findings also suggest stronger men are more likely to be in long-term relationships, supporting the "provisioning" theory.

Multifocal Lenses Reduce Myopia Risks

New research demonstrates that high-add multifocal contact lenses significantly slow myopia progression in children, with benefits that persist even after discontinuation. The lenses, designed to slow eye growth and reduce long-term myopia-related risks, showed no rebound effect after treatment stopped.

Neurology News Articles

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

Hearing Loss May Signal Increased Risk of Parkinson’s Disease

A new study has identified a potential link between hearing impairment and an increased risk of developing Parkinson’s disease. Researchers analyzed data from over 159,000 individuals, finding that every 10-decibel increase in hearing loss corresponded to a 57% higher risk of Parkinson’s.

Biodegradable Brain Electrodes Advance Neural Repair

Researchers have developed a flexible, biodegradable electrode capable of stimulating neural precursor cells (NPCs) in the brain, offering a safer and more precise alternative for neural repair. The electrode dissolves naturally after seven days, eliminating the need for surgical removal while promoting tissue regeneration.

Almost Half of Americans Over 55 Face Dementia Risk

New research finds that the lifetime risk of dementia after age 55 in Americans is 42%, significantly higher than previous estimates. Women face a higher risk (48%) than men (35%) due to their longer life expectancy. Risk factors include genetic predisposition, hypertension, diabetes, obesity, and limited physical activity.

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.

AI Reveals Gene Activity in Human Cells

Researchers have developed an AI model that accurately predicts gene activity in any human cell, providing insights into cellular functions and disease mechanisms. Trained on data from over 1.3 million cells, the model can predict gene expression in unseen cell types with high accuracy. It has already uncovered mechanisms driving a pediatric leukemia and may help explore the genome's "dark matter," where most cancer mutations occur.

AI Predicts Autoimmune Disease Progression with New Genetic Tool

Researchers have developed a Genetic Progression Score (GPS) using artificial intelligence to predict the progression of autoimmune diseases from preclinical symptoms to full disease. The GPS model integrates genetic data and electronic health records to provide personalized risk scores, improving prediction accuracy by 25% to 1,000% over existing models.

Revolutionizing Brain Diagnostics with Light and AI

A new "molecular lantern" technique allows researchers to monitor molecular changes in the brain non-invasively using a thin light-emitting probe. This innovative tool utilizes Raman spectroscopy to detect chemical changes caused by tumors, injuries, or other pathologies without altering the brain beforehand.

Psychology News Articles

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

Decoding Favoritism: How Parents Shape Sibling Bonds

New research sheds light on how parents subtly favor children based on birth order, personality, and gender, shaping family dynamics. Younger siblings often receive more favorable treatment, while older siblings are granted greater autonomy.

Delayed Brain Maturation Links Genetics and Eating Disorders

Over half of 23-year-olds display restrictive, emotional, or uncontrolled eating behaviors, with delayed brain maturation playing a significant role. The research linked structural brain differences, mental health challenges, and genetic predispositions to the development of disordered eating behaviors from adolescence to adulthood. MRI data showed delayed cortical thinning in unhealthy eaters, especially in regions like the cerebellum, which regulates appetite.

Physical Neglect Causes Lifelong Social Challenges in Children

A new study highlights how childhood physical neglect disrupts social development more than physical, emotional, or sexual abuse. Neglected children were less social, less popular, and less connected to cohesive friend groups, facing stigmatization and withdrawal.

Indoor Temperatures Affect Cognitive Function in Older Adults

A new study reveals that older adults experience the least attention difficulties when home temperatures remain between 68–75 ˚F (20–24 ˚C). Deviations beyond this range double the risk of attention lapses, highlighting how even current climate conditions may harm cognitive health.

Soundless Minds: When the Mind Hears No Inner Voice

Some people experience anauralia, a silent mind incapable of imagining sounds like voices or music. Scientists and creatives will explore this phenomenon at the "Mind’s Ear and Inner Voice" conference in April, hosted in Auckland.

Lithium Restores Brain Function and Behavior in Autism

Lithium, a drug widely used for bipolar disorder, may also treat autism spectrum disorder (ASD), according to new research. The study found that lithium restored brain function and reduced behavioral symptoms in mice with Dyrk1a gene mutations, a known ASD risk factor.

New Genetic Link to Autism Identified on X Chromosome

Researchers identified variants in the DDX53 gene, located on the X chromosome, as contributors to autism spectrum disorder (ASD). These genetic variants, found predominantly in males, provide critical insights into the biological mechanisms behind autism’s male predominance. The study also uncovered another potential gene, PTCHD1-AS, near DDX53, linked to autism, emphasizing the complexity of ASD’s genetic architecture.

Estrogen Drives Binge Drinking Behavior in Females

The hormone estrogen increases binge drinking in females by enhancing activity in neurons within the brain's BNST region. The effect is particularly strong during high-estrogen phases, leading to "front-loading," or rapid alcohol consumption within the first 30 minutes of availability.
