Dogs Can Sniff Out Parkinson’s Disease

Trained detection dogs can identify Parkinson’s disease (PD) with remarkable accuracy by sniffing skin swabs, according to a new study. In double-blind trials, the dogs achieved up to 80% sensitivity and 98% specificity, even when samples came from patients with other health conditions.

This shows the outline of a person and a brain.

Immune System Tied to Mental Health Disorders

New research reveals that immune system activity may play a causal role in conditions like schizophrenia, depression, and Alzheimer’s disease. Using Mendelian randomisation, scientists linked 29 immune-related proteins to seven neuropsychiatric disorders, suggesting the brain is not the only organ involved in mental health.

Eating Seafood Linked to Kinder, More Socially Skilled Young Children

Children who regularly eat seafood at age 7 exhibit more positive social behaviors—such as sharing, helping, and interacting kindly—by ages 7 and 9, compared to those who rarely consume seafood. This finding, from a large study tracking nearly 6,000 children, underscores seafood’s role in supporting behavioral and social development during childhood.

Mosaic Brain Evolution Drives Learning in Tropical Butterfly

Researchers have discovered that Heliconius butterflies, known for feeding on both nectar and pollen, show mosaic brain evolution with specialized neural expansions linked to enhanced learning and memory abilities. This expansion occurs in specific brain structures called mushroom bodies, which are key for long-term visual memory and spatial learning.

Critical Brain Development in Toddlers at 16 Months

Researchers found that 16-month-old toddlers engage more brain regions to develop cognitive skills like inhibitory control. Using functional near-infrared spectroscopy (fNIRS), the study showed increased brain activity in the prefrontal and parietal cortex. Despite no observable improvement in skills, significant brain changes were noted between 10 and 16 months. This highlights 16 months as a crucial period for developing the ability to follow instructions and control impulses.

Happiness Takes Practice

Happiness can indeed be learned through courses like their 'Science of Happiness', which educates students on evidence-informed habits for well-being. However, a follow-up study indicates that the initial boost in well-being requires sustained effort and continued practice of these habits, such as gratitude and meditation, to maintain long-term benefits.

Genetic Driver of Anxiety Discovered

An international team of scientists has identified a gene in the brain responsible for anxiety symptoms and found that modifying the gene can reduce anxiety levels, offering a novel drug target for anxiety disorders. The discovery highlights a new amygdala miR483-5p/Pgap2 pathway that regulates the brain's response to stress and provides a potential therapeutic approach for anxiety disorders.
