Researchers at the University of Electronic Science and Technology of China have developed a novel quantum algorithm that extends Grover's quadratic speedup to continuous search problems, including optimization and spectral analysis over infinite-dimensional spaces. The team rigorously proved the algorithm's optimality by establishing a matching lower bound on query complexity. They also proposed a general framework for constructing the required quantum oracle, enhancing adaptability to diverse applications.

Pituitary neuroendocrine tumors (PitNETs) are usually removed by endoscopic endonasal surgery (EES). However, surgical management of giant and irregular pituitary neuroendocrine tumors (GIPitNETs) with EES is often challenging, due to their large size and irregular shape. An alternative approach is combined endoscopic endonasal and transcranial surgery (CECS). Now, researchers compare the efficacy and outcome of both surgical techniques for treating GIPitNETs and found that CECS is safe and effective with comparable complication rates.

In a paper published in National Science Review, a research team led by Chinese scientists quantifies changes in dissolved carbon storage within China's lakes and reservoirs alongside dissolved carbon fluxes in rivers over the past three decades, systematically revealing how climate change, anthropogenic disturbances, and water chemistry factors collectively drive the dynamics of dissolved carbon in inland waters. The study finds that dissolved carbon storage across China's inland waters has increased significantly during this period, with riverine carbon fluxes primarily driven by climate and human factors, while lake and reservoir carbon storage is dominated by water chemistry controls.

A research team from Shaanxi Normal University developed a novel catalyst that transforms glycerol waste from bio-diesel production into high-value glyceric acid with remarkable 96.6% selectivity. The innovative Pt-Bi₂O₃ nanosheet catalyst achieves superior performance through a unique synergistic effect: bismuth oxide modifies platinum's electronic structure while controlling glycerol's adsorption orientation. This green upgrade path not only addresses industrial waste challenges but offers a sustainable route to valuable chemicals. The catalyst also shows promising versatility for converting other polyols, opening doors for broader industrial applications.

A recent study published in National Science Review has revealed a previously unknown separated two-phase structure in lithium-manganese-rich cathodes, a breakthrough that could revolutionize the design of high-performance batteries. The discovery allows researchers to precisely manipulate the internal structure of cathodes, offering new opportunities for developing batteries with significantly higher energy density.

Neuroform Atlas Stent (NAS) is used in treating localized dilation of blood vessels in the brain. The stent is designed for placement in vessels of 2.0─4.5 mm diameter. However, studies that assess whether NAS is equally effective in smaller blood vessels are limited. Researchers from China addressed this critical clinical question, and report that even in smaller vessels of diameter less than 2.5 mm, NAS-assisted coiling led to fewer complications and favorable short-term outcomes.
