Young adults who are not motivated to eat healthily can still be engaged with the right type of communication, according to new research from the European Food Information Council (EUFIC). Young adults often face unique dietary challenges, from limited resources and time constraints to social and emotional barriers to healthy eating. The study, “Healthy Eating for Young Adults: Communication in Early Stages of Behaviour Change,” published in the Journal of Nutrition Education and Behavior, explored how 18- to 25-year-olds in the U.K. respond to infographics about healthy eating designed for those not yet committed to changing their diets.

Long-acting antiviral medications are transforming HIV prevention and care, requiring only minimalistic dosing. But as the use of lenacapavir expands, scientists are probing a critical question: If the virus evolves resistance, does it also pay a cost?

Tiny RNA molecules carried by extracellular vesicles in the bloodstream can accurately predict kidney function decline and cardiovascular risk in chronic kidney disease (CKD), as reported by researchers from Science Tokyo. By analyzing blood samples from a large cohort, the team identified multiple microRNAs linked to disease progression and built a model to distinguish high-risk patients with CKD. Clinically applying this risk score model can contribute to improved patient outcomes.

Ketamine is a powerful anesthetic used for surgery and acute pain management. But in recent years, it has also gained a reputation as a potential treatment for certain mental health conditions like stress and anxiety. In a new study published in the journal Physiology & Behavior, scientists suggest another possible use for ketamine as a protective shield for the brain during turbulent adolescent years.

Adults age 65 and older who completed five to six weeks of cognitive speed training—in this case, speed of processing training, which helps people quickly find visual information on a computer screen and handle increasingly complex tasks in a shorter time period—and who had follow-up sessions about one to three years later were less likely to be diagnosed with dementia, including Alzheimer’s disease, up to two decades later, according to new findings published today in Alzheimer’s & Dementia: Translational Research and Clinical Interventions.
