Vascular topology and hemodynamics define tissue perfusion boundaries, providing essential information for surgical margin planning, vessel preservation, and postoperative functional assessment. Scientists in China developed PAATAM, a real-time photoacoustic tracking and mapping strategy that fuses vascular geometry and signal-intensity features to estimate six-degree-of-freedom handheld probe motion. The method reconstructs globally consistent panoramic 3D vascular maps with 99.67% registration accuracy, opening new avenues for photoacoustic surgical navigation and functional vascular assessment.

A novel interpenetrated RuO₂/Co₃O₄ heterostructure catalyst is developed, which synergistically couples the traditional adsorbate evolution mechanism (AEM) with the more efficient oxide pathway mechanism (OPM) for acidic oxygen evolution, achieving exceptional activity and stability that far surpass commercial RuO₂.

All eyes were on Quaise Energy at the 2026 Geothermal Rising Conference, the flagship conference for the geothermal industry, in late September. The news related to Quaise included: the announcement of up to $25 million funding from the US Department of Energy, a talk on the company’s progress to date on what it believes will be the world’s first commercial superhot geothermal power plant, and major awards to two employees.
