Hafnia-based ferroelectric memories are emerging as promising candidates for next-generation nonvolatile memory because they combine excellent scalability with compatibility with CMOS technology. Further reducing the thickness of ferroelectric films can lower operating voltage and increase storage density, but maintaining reliability at high temperatures becomes increasingly challenging. Researchers at Fudan University have now shown that tailoring the size and orientation of ferroelectric grains can help address this challenge. Their ultrathin devices remain highly stable at 225 °C, pointing to a route toward dense and reliable ferroelectric memories for harsh thermal environments. The study was published in Science Bulletin.

Many women experience cognitive fog or memory impairment during pregnancy or while taking oral contraceptives. A new study published in Science Bulletin reveals that sustained high levels of estrogen disturb a specific neural circuit connecting the lateral hypothalamus to the hippocampus, leading to temporary memory loss. This discovery provides a long-sought biological explanation for "mom brain" and reconciles decades of conflicting data on estrogen's effects on memory

A phase 3 randomized controlled trial involving 614 patients with acute ischemic stroke who did not receive reperfusion therapy found that oral edaravone (TTYP01) initiated within 24 hours of symptom onset and continued for 28 days significantly improved functional outcomes. At 90 days, 65.4% of patients in the treatment group achieved excellent functional recovery (mRS 0–1) compared with 47.1% in the placebo group (OR 2.12, 95% CI 1.53–2.94, P <0.001). No significant differences in safety events were observed between the two groups.

Parkinson’s disease is expected to cause a substantial economic burden from 2020 to 2040, amounting to 473 billion CNY in constant 2024 prices, which represents 0.017% of projected GDP in China. Utilizing a health-augmented macroeconomic model across 31 provinces, researchers found that disease-induced reductions in physical capital accumulation outweigh labor supply declines in most regions. The findings support tailored prevention and long-term care strategies.

A new review in Medicine Plus traces a century of deep brain stimulation (DBS), explaining how the therapy alters pathological activity from local circuits to whole-brain networks, and mapping targets and clinical evidence across 16 neurological and psychiatric disorders. It also examines adaptive stimulation, directional leads, and biomarker-guided approaches that could make treatment more precise and personalized.
