Could a cooler room help you burn more calories? scientists investigate.
Knowledge-focused CompletedThis study looked at how being in different temperatures (from about 61°F to 88°F) affects how many calories healthy adults burn. Researchers also checked for brown fat activity, a type of fat that burns energy to keep you warm. 104 healthy men and women stayed in a hospital unit…

Brain scans reveal dopamine disruption in opioid addiction
Knowledge-focused CompletedThis completed study looked at how opioid use disorder changes dopamine signaling in the brain. Researchers used PET and MRI scans to compare people with opioid use disorder (some on medication, some not) to healthy volunteers. The goal was to understand differences in dopamine r…

Does sleep clean your brain? new study investigates
Knowledge-focused CompletedThis study looked at whether sleep helps the brain clear out a waste product called amyloid-beta, which is linked to Alzheimer's disease. Twenty-two healthy adults had brain scans after a full night's sleep and after being kept awake all night. The goal was to see if sleep affect…

Healthy brains scanned twice to test reliability of imaging methods
Knowledge-focused CompletedThis study looked at how consistent brain scans are when repeated in healthy adults. 112 volunteers had MRI and PET scans to measure brain connections and activity. The goal was to improve future research on brain diseases by understanding normal brain function and scan reliabili…

Antibiotics may do more than fight infection – new study investigates hidden effects
Knowledge-focused CompletedThis study looked at how two common antibiotics (amoxicillin and azithromycin) affect the trillions of microbes living in healthy people. Researchers measured changes in metabolism, immune markers, and energy use before, during, and after a short course of antibiotics. The goal w…

Brain scan study reveals how rest helps lock in new skills
Knowledge-focused CompletedThis study looked at how different layers of the brain's motor cortex help us learn and remember new movement skills. Forty healthy, right-handed adults practiced typing sequences and had their brains scanned with MRI. The goal was to see which brain layers are most active during…

Scientists test brain zapping methods on healthy volunteers
Knowledge-focused CompletedThis study tested different ways to apply non-invasive brain stimulation (like magnetic pulses) in 83 healthy adults aged 18-65. The goal was to learn how to make these techniques more effective for diagnosing and treating brain disorders. Participants completed tasks, had brain …
