For the first time, researchers have shown that ketamine activates two separate mechanisms in the brain, one for pain relief and another for altering the state of consciousness.
The findings may help in developing treatments that provide the benefits of ketamine while reducing its psychological side effects.
Carbonate cerium and neodymium isotope records from South China show that low-oxygen waters invaded shallow habitats twice during the Late Ordovician Mass Extinction, with a brief recovery between the two pulses. Earth-system models suggest that rapid climate swings reorganized continental weathering and nutrient delivery, amplifying marine oxygen loss and ecological stress.
The research team from National University of Defense Technology systematically described the memory efficiency issues in the training process of large language models (LLMs) with Transformer architecture for scientific fields. As the scale of models continues to expand, memory requirements have become a key bottleneck restricting their applications in scientific fields such as biology, medicine, chemistry, and meteorology. The article systematically reviewed memory-efficient pre-training technologies at the algorithm level, system level, and software-hardware collaborative optimization, and combined with the AlphaFold 2 case, demonstrated how customized memory optimization methods can reduce storage overhead while maintaining prediction accuracy.
Coronary artery disease remains the top global cause of death, yet current clinical practice often targets advanced vessel narrowing and ischemia, missing opportunities for early prevention before heart attacks occur. This peer‑reviewed commentary, inspired by The Lancet Commission, synthesizes real‑world Chinese population data showing atherosclerotic plaques are common among middle‑aged and older adults, with coronary plaque prevalence reaching 44.9% in local community cohorts aged 50‑75 years. The authors outline a stepwise, risk‑stratified screening workflow for primary‑care settings to detect subclinical plaque, prioritize systemic medical therapy over routine stenting for non‑culprit unstable lesions, and integrate inflammation and environmental risk control. The authors note that robust long‑term randomized trial evidence is still needed to validate broad implementation of plaque‑guided care.
Summer break can bring changes in daily routines that make it harder for adolescents to maintain healthy habits. Researchers from Pennington Biomedical Research Center, FMOL Health | Our Lady of the Lake Children’s Health and LSU are exploring how technology can help keep adolescents engaged in healthy behaviors during and after a structured summer program.
A pilot study tested an eight-week summer health promotion program that combined an in-person camp with an AI-assisted mobile app, wearable activity trackers and personalized behavioral support.
