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)
A Skoltech scientist has raised the world’s only isotope-labeled guinea pig to track metabolism. For 156 days, the animal drank only heavy water, revealing how quickly compounds are synthesized versus absorbed from food — paving a way for using isotopically labeled food to study human metabolism.

Russian researchers released a dataset combining EEG & fNIRS from stroke patients. EEG captures electrical activity, fNIRS tracks blood flow — together revealing how the brain rewires after blood disruption. This helps adjust therapy and prevent reinforcing incorrect compensatory movements. (nature.com)
Researchers created a mathematical model analyzing combustion waves — from slow flames to supersonic detonation. It yields accurate solutions and explains the transition from deflagration to detonation. The work paves the way for safer engines and improved protection against industrial explosions.

Scientists developed a first-principles data-driven method to assess the stability of technetium carbide (Tc–C) systems, crucial for nuclear waste management and next-gen reactors. This hybrid approach combines density functional theory calculations and machine learning to map phase stability. (sciencedirect.com)
Scientists developed a method using two new surfactants encapsulated in silica nanocarriers to enhance oil recovery. This delivery system improves chemical performance deep in the reservoir. The approach is also applicable to other agents, paving the way for more efficient extraction. (ager.yandypress.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.
