The study urges parents, educators, and clinicians to pay attention to why young people turn to chatbots.
A new kinetic model reconciles field observations and laboratory experiments, showing that temperature dependence and multiphase kinetics resolve observed growth rates. The model considers reactivity, diffusivity, and concentration gradients of chemical species across gas and condensed phases.
Dr. Emily Flanagan's five-year NIH grant will investigate how energy intake and expenditure influence infant growth and future obesity risk. The study aims to improve energy-intake standards for infants and identify critical periods for interventions promoting healthy growth.
Researchers found lead levels were 7 times higher near airports compared to other areas of Portland, with aviation fuel as the dominant source. The study highlights the need for soil testing to address lead exposure risks for children.
A recent study from the Dog Aging Project found that dogs with five or more chronic diseases were more than twice as likely to die as dogs living with only one diagnosed condition. Chronic diseases can dramatically shorten a dog's lifespan, highlighting the importance of managing multiple diseases together rather than individually.
The American Academy of Neurology has launched BrainHealth.com, a public resource providing expert-reviewed information, tools, and stories to improve brain health. The website offers trustworthy guidance, practical resources, and personal stories to help people navigate brain health with confidence.
A new study from the University of California San Diego reveals that the brain tracks subtle variations in breathing to decode neural activity patterns. Researchers found a precise connection between breathing patterns and brain activity, offering new avenues for understanding disorders like SUDEP and SIDS.
Research reveals individual breaths at rest create unique brain wave patterns, affecting mental processes such as thinking, attention, and emotional regulation. The study suggests that brain-body interactions are crucial for assessing and treating neuropsychiatric patient populations.
Researchers developed tools to compare tumor microenvironments and predict treatment response by analyzing spatial transcriptomic data. The new tools provide a detailed map of tumor cell organization, enabling clinicians to quickly analyze and compare tumor 'floor plans' and determine the best course of treatment.
