New study shows unstructured time drives teenage delinquent behavior

A study involving more than 58,000 adolescents from 21 countries found that "unstructured free time" – defined as periods without adult supervision or activities guided by educational, cultural, or athletic goals – is strongly associated with delinquent behavior and exposure to violence among young people.

Microcurrent stimulation shows immediate reduction in surgical scar depth

A newly accepted pilot study in the Journal of Bodywork & Movement Therapies reports that direct-current (DC) microcurrent stimulation was associated with a statistically significant reduction in measured postsurgical scar depth immediately following a single treatment.

Shared cellular pathway drives neurodegeneration in rare childhood dementia and Alzheimer’s

Researchers at University of California San Diego and their colleagues have identified a key cellular pathway that drives brain degeneration in both a rare childhood disorder and the far more common Alzheimer's disease.

LVIS stent-assisted coiling effectively treats wide-necked intracranial aneurysms

Intracranial aneurysms are weakened, bulging areas of cerebral arteries that can rupture, causing subarachnoid hemorrhage and, in turn, significant disability or death.

Adolescents using nicotine face higher risks of mental health problems

Adolescents who use nicotine are more likely to report symptoms of anxiety, depression, and other mental health problems than their peers who do not use nicotine.

New review urges proteostatic fitness standards for stem cell therapies

Stem cell therapies have expanded rapidly, with more than 115 clinical trials involving over 1,200 patients approved by late 2024. The U.S. Food and Drug Administration (FDA) recently approved Ryoncil (remestemcel‑L) for children with steroid‑refractory acute graft‑versus‑host disease, signaling a major shift toward routine clinical use.

Early-life stress rewires brain epigenetics to heighten sensitivity to future stress

. Early-life stress increased SETD7 and H3K4me1 in the ventral tegmental area of mice, creating an epigenetically primed state that heightened later transcriptional, neuronal, and behavioral responses to stress. Reducing Setd7 during development lowered H3K4me1 and weakened these stress-sensitizing effects, identifying a mechanism that may help explain how early adversity leaves lasting biological effects.

Rising marine heatwaves create growing challenges for human health

The devastating impacts of marine heatwaves extend far beyond dying coral reefs and declining fisheries, with new research warning these extreme ocean warming events are posing a growing threat to humans' physical and mental health.

Natural hormone activates brain-to-liver signaling pathway to suppress liver inflammation

Researchers at McMaster University have discovered that a naturally occurring hormone best known for suppressing appetite and promoting weight loss also helps protect the liver from inflammation through a previously unknown signalling pathway, opening new possibilities for treating advanced fatty liver disease.

Newly discovered protein pathway limits spinal cord injury damage

Spinal cord injury begins with immediate mechanical damage, but much of the lasting neurological loss develops during the secondary phase, when inflammation, oxidative stress and disrupted metabolism continue to injure surviving tissue.

Why pulses could play a bigger role in healthy and sustainable diets

A narrative review finds that pulses may support gut and metabolic health through their fiber, protein, phytochemicals, and interactions with the gut microbiota, while offering a lower environmental footprint than many animal protein sources. Human evidence is strongest for selected cardiometabolic outcomes, while many microbiome and fermentation-related benefits remain supported mainly by animal and laboratory studies.

Fine particle pollution raises rheumatoid arthritis flare risk and disease activity

Higher ambient PM2.5 exposure was associated with increased rheumatoid arthritis disease activity and a greater likelihood of flares in a four-year South Korean cohort of 1,070 patients. The association appeared stronger with sustained exposure over approximately two weeks or longer, while women and nonsmokers showed more pronounced links between PM2.5 and DAS28-CRP.
