New computer model lets researchers simulate how brain circuits make decisions

Every day, your brain makes thousands of decisions under uncertainty. Most of the time, you guess right. When you don't, you learn. But when the brain's ability to judge context or assign meaning falters, thoughts and behavior can go astray.

Cannabis and tobacco co-use linked to shifts in brain's 'bliss molecule'

People who use both cannabis and tobacco show distinct brain changes compared to those who use cannabis alone, according to a new study led by McGill University researchers at the Douglas Research Centre.

Genetic inflammatory signature defines depression subtypes and treatment response

Researchers led by Prof. Alessandro Serretti at Kore University of Enna have identified a genetic inflammatory signature that defines specific depression subtypes and influences how patients respond to antidepressant medications, according to new peer-reviewed research published today in Genomic Psychiatry.

Neighborhood environments can influence a child's risk of developing type 2 diabetes

Type 2 diabetes (T2D), once considered an adult-onset disease, is increasing at alarming rates in children and adolescents. Before the mid-1990s, just 1% to 2% of youth with diabetes had T2D.

Molecular evidence connects higher childhood cognitive function to longer lifespan

Researchers led by Dr. W. David Hill at the University of Edinburgh have identified a significant genetic correlation between childhood cognitive function and longevity, providing the first molecular genetic evidence that intelligence measured in youth shares genetic factors with lifespan.

Food allergy diagnoses plummet after guideline implementation

Peanuts represent one of the most common causes of immunoglobulin E (IgE)-mediated, or anaphylactic, food allergies in children, yet a landmark study found that early introduction of peanut to infants may lower their risk of developing this allergy.

Heavy drinking fuels Alzheimer’s disease by igniting brain inflammation and protein damage

Chronic alcohol use accelerates Alzheimer’s disease (AD) progression by intensifying oxidative stress, neuroinflammation, and amyloid-tau pathology through shared molecular pathways. The review highlights emerging therapies, targeting TLR4, GSK-3β, and metabolic dysfunction, that may mitigate alcohol-induced neurodegeneration.

Common hospice medications may carry major unintended risks for people with dementia

Hospice care aims to bring comfort, peace, and dignity to patients at the end of life. Yet for the growing number of Americans with dementia who enter hospice, their course is often long and unpredictable - making it especially important to ensure treatments align with each person's goals and stage of illness.
