Summary: A new study of Japanese undergraduates finds that students’ perceptions of their own athletic ability are shaped by a mix of personality traits, childhood environment, and social feedback. Those who rated themselves as more athletic also tended to display grit, resilience, and a growth mindset.Factors like early walking age,...
Smart device monitors the head waste system
Summary: A new wearable device has been developed to noninvasively monitor the brain’s glymphatic system, which helps clear waste and may play a role in neurological conditions like Alzheimer’s. Traditionally only measurable via MRI, researchers can now observe this system throughout different sleep stages using a head cap embedded with...
Long-Term Weight Loss in the Middle Age Tied to Length Advantages
Summary: A long-term study of 23,000 adults from Finland and the UK has found that overweight individuals who lost just 6.5% of their body weight in early midlife and maintained the loss enjoyed significant health benefits over decades. The study, spanning 12 to 35 years, is one of the first...
Sleep help properly protect the brain from Alzheimer’s Disease.
Summary: A common sleep medication, lemborexant, may do more than promote rest—it appears to reduce harmful tau buildup and protect the brain from neurodegeneration in mouse models of Alzheimer’s disease. Researchers found that this orexin receptor antagonist not only restored healthier sleep patterns but also preserved brain structure and reduced...
The Brain’s Vast Memory Power Could Be Found in Astrocytes, which Could Be the Major to its Vast Memory.
Summary: New research proposes that astrocytes—long thought to be merely supportive cells—may significantly enhance the brain’s ability to store memories. Unlike neurons, astrocytes cannot fire electrical signals but can influence synaptic activity through calcium signaling and gliotransmitters.A computational model based on dense associative memory suggests astrocytes could link multiple neurons...
A 10-year study that examines mental aging provides information for research.
Summary: A decade-long brain health study has released its full dataset, offering rare longitudinal insights into how cognition and brain structure change across adulthood. The Dallas Lifespan Brain Study tracked nearly 500 individuals from age 21 to 89 over three timepoints using brain scans, cognitive tests, and health surveys.Findings highlight...
Autism and Early-Onset Parkinson’s Chance: A Link Found
Summary: A large-scale Swedish study has found that individuals with autism are at significantly higher risk of developing early-onset Parkinson’s disease. Researchers followed over two million people and discovered that those with autism were four times more likely to develop the neurodegenerative condition before age 50.The connection may stem from...
Singing to kids improves mood and bond
Summary: A new randomized study found that when parents sing more frequently to their infants, both babies and caregivers experience measurable improvements in mood and wellbeing. The study involved 110 caregiver-infant pairs who participated in a four-week music enrichment intervention via smartphone.Results showed that singing increased significantly, especially in soothing...
LLMs mimic people mental disorder
Summary: A new study reveals that GPT-4o, a leading large language model, displays behavior resembling cognitive dissonance—a core human psychological trait. When asked to write essays either supporting or opposing Vladimir Putin, GPT-4o’s subsequent “opinions” shifted to align with its written stance, especially when it “believed” the choice was its...
Cats You Smell Together and Know Their Proprietors.
Summary: A new study has found that domestic cats can distinguish between their owner’s scent and that of a stranger using their sense of smell alone. When presented with scent samples from familiar and unfamiliar humans, cats consistently spent more time sniffing the unfamiliar scent.This behavior suggests cats may use...
