How to treat opioid use disorder in health systems

A new study from Ohio State University suggests that routinely offering and initiating medication-based treatment for opioid use disorder can lead to improved patient outcomes. The program, which expanded access to care in emergency, inpatient, and outpatient settings, saw over 4,900 medication initiations in its first four years.

New study shows young adults who use high strength cannabis do not ‘titrate’ to less risky levels of use

A new study found that young adults using high-strength cannabis in California tend to consume more and experience greater symptoms of cannabis use disorder. The study, which surveyed over 400 participants, showed a significant association between THC potency and cannabis consumption frequency and quantity.

Do you want to freeze a cloud? Desert dust might help

Researchers at ETH Zurich found that mineral dust particles can trigger freezing of cloud droplets, particularly important in northern regions where clouds form below freezing temperatures. This process affects sunlight reflection and precipitation generation, with major implications for climate models.

Saliva testing may reveal early signs of diabetes and obesity

Researchers at UBC Okanagan have found that measuring insulin levels in saliva can detect early metabolic changes linked to obesity and Type 2 diabetes. The study suggests that waist circumference may be a more reliable indicator of hyperinsulinemia than age or overall body weight.

Study pinpoints key mechanism of brain aging

A new study by Stanford researchers reveals that declining proteostasis in the brain leads to increased protein aggregation, which is linked to neurodegenerative diseases. The findings were made using the turquoise killifish model, and shed light on the fundamental molecular principles of aging.

Protecting your beating heart

A team of researchers is using NCSA resources to simulate the long-term progression of atrial fibrillation, a type of irregular heartbeat. By modeling the heart's electrical activity, they have uncovered a vicious cycle where adaptations to maintain calcium balance lead to continued arrhythmias and eventually a permanent condition.

The clinical practice guideline update on adult sinusitis emphasizes patient education, shared decision-making, and evidence-based treatment options

The updated guideline emphasizes watchful waiting as the preferred approach for most bacterial sinus infections, while also providing clearer guidance on antibiotic use. The new recommendations aim to reduce unnecessary antibiotic prescriptions and promote effective symptomatic treatments.

MXene‑Ti3C2Tx‑based neuromorphic computing: physical mechanisms, performance enhancement, and cutting‑edge computing

This review highlights the potential of MXene-Ti3C2Tx as a universal platform for neuromorphic devices, offering sub-femtojoule synaptic events and nanosecond response times. The material enables flexible, multimodal, and biocompatible systems that classical silicon cannot match.

Pediatric investigation study identifies the optimal dose of methylprednisolone for treating severe mycoplasma pneumoniae pneumonia

Researchers conducted a randomized clinical trial to compare low- and high-dose methylprednisolone with azithromycin for treating severe Mycoplasma pneumoniae pneumonia. The study found that lower dose regimen of glucocorticoids is sufficient, equally effective, and safer than the high dose regimen.

Not all low-grade prostate cancers are low risk

A new study found that one in six men with low-grade prostate cancer (GG1) actually have intermediate- or high-risk cancer when other clinical features are considered. This suggests that relying on biopsy grade alone can lead to underestimating disease risk and misclassifying individuals who may benefit from definitive treatment.

Researchers reveal spatiotemporal coordination between pre-rRNA processing and nucleolar architecture

The study reveals a spatiotemporal separation in the processing of distinct pre-rRNAs within the nucleolus, contradicting traditional models. The findings suggest that small subunit (SSU) pre-rRNA is predominantly processed within the inner FC–PDFC regions, while large subunit (LSU) pre-rRNA matures gradually in the outer PDFC–GC regions.

Modified near-infrared annealing enabled rapid and homogeneous crystallization of perovskite films for efficient solar modules

Researchers have developed a modified near-infrared annealing process that turns blade-coated perovskite films into record-performing solar modules in just 20 seconds. The process slashes processing time by 30 times and halves energy use while delivering superior film quality.
