A research paper by scientists at Peking University Third Hospital proposed a parameter-adjustable photobiomodulation (PBM) therapy apparatus to screen for the optimal PBM parameters for treating ischemic stroke and preventing post-stroke cognitive impairment (PSCI).

The new research paper, published on May. 6 in the journal Cyborg and Bionic Systems, provide a PBM therapy apparatus with custom parameters. By evaluating the treatment effect, we identified that 755 nm was the optimal light wavelength for ischemic stroke in rats with transient middle cerebral artery occlusion/reperfusion.

Two BeiDou-3 satellites, once plagued by puzzling orbit errors, are now operating with newfound precision thanks to a breakthrough modeling strategy. 

As cancer neuroscience continues to evolve, this review delves into the pivotal role of neurotransmitter receptors at the intersection of neurobiology and tumor biology. By analyzing involvement in key signaling pathways such as β-adrenergic and GABAergic, the study uncovers how these receptors drive cancer progression, modulate immune responses, and contribute to therapy resistance. Highlighting emerging NR-targeted therapies, the review sets the stage for more personalized, precision-based cancer treatments and marks a promising direction for future research. 

Precision in droplet formation is key to advancing lab-on-a-chip technologies.

Achieving unidirectional signal flow—where information travels in only one direction—is vital for next-generation communication systems.

Flexible organic near-infrared (NIR) sensors are gaining significant attention across various applications, particularly in clinical settings, where they hold the potential to significantly enhance human wellbeing. This review highlights recent advancements in flexible organic photodetectors (OPDs) and examines the opportunities and technical challenges in diverse fields such as environmental pollution monitoring, bioimaging, food testing, automotive applications, healthcare, artificial vision, wearable electronics, and optical communication.

Researchers have unveiled the first comprehensive analysis of China's urban expansion from 1990-2020, revealing how cities have adapted to their environments and faced varying disaster risks. The study found that while 83% of urban development occurred in suitable areas, 14% expanded into high-risk zones, with eastern regions facing water-related disasters, western regions threatened by earthquakes, and northeastern areas vulnerable to extreme cold.

In a paper published on aBIOTECH, the authors identified resistance-breaking Potato virus Y (PVY RB) isolates and emerging potyviruses (TVBMV and ChiVMV) in Yunnan tobacco fields, and revealed that combined inactivation of eIFiso4E-T in the va (lacking eIF4E1-S) genetic background confers durable resistance to PVY, while knockout of eIFiso4E-S in the va genetic background confers resistance to TVBMV and ChiVMV; pyramiding mutations in these genes achieved broad-spectrum potyvirus resistance without compromising plant growth, offering a novel strategy for engineering resistance crops.

Spin photonics enables precise optical manipulation but faces bandwidth constraints. Researchers in China developed a folded-path metasurface platform that achieves independent dispersion and phase control of two opposite spin states, overcoming this fundamental barrier. This innovation realizes achromatic focusing, spin Hall effects, and spatiotemporal vector fields using a single metasurface, opening new avenues for a wide range of innovations, from dynamic control of light-matter interactions to the development of next-generation spin-photonic devices.
