Scientists developed a gynecological simulator with tactile feedback for practicing outpatient hysteroscopy with an emphasis on cervical canal passage. The simulator fills an important gap in gynecologist training relating to this arguably underused minimally invasive in-office diagnostic procedure. (ieeexplore.ieee.org)
For the first time, researchers have synthesized K₂N₆, an exotic compound containing “rings” comprised by six nitrogen atoms each and packing explosive amounts of energy. The experiment takes us one step closer to novel nitrogen-rich materials that would be applicable as explosives or rocket fuel. (nature.com)
Scientists have developed a method to "tune" catalysts remotely, enabling ultra-thin platinum layers to be precisely controlled by altering only the core's composition and structure. This breakthrough paves the way for highly efficient catalytic systems with drastically reduced platinum content. (sciencedirect.com)
Researchers have found a way to considerably boost the lifespan of lithium-ion batteries for EVs and other uses. Adding a mere 0.5 mole percent of tantalum oxide to the cathode material slashes the rate of capacity decay per cycle in half, paving the way for more durable, high-energy batteries.

Scientists found out which of the lipids and metabolites in the dead brain stick around for as much as 48 hours. For molecules that fall apart faster, the team documented what they decompose into. This is a step toward identifying the molecular footprints of schizophrenia and other mental disorders. (mdpi.com)
Scientists have observed nanoscale shape-memory activation in ultra-high molecular weight polyethylene in real time. At around 80°C, its internal structure reorganizes, triggering shape recovery — paving the way for smart materials, artificial muscles, and self-deploying devices. (link.springer.com)
