Success after refractive surgery is often measured by visual acuity, but patients also care about how comfortable their vision feels in daily life. Glare, halos, haze, blurred vision, and night-vision discomfort can shape the early postoperative experience even when the eye chart looks excellent. A new prospective cohort study published in Eye Discovery by researchers from the Eye and ENT Hospital of Fudan University and collaborating institutions provides a detailed early picture of both objective and subjective visual quality after keratorefractive lenticule extraction using the VISUMAX 800 platform.

Diabetic foot ulcers can remain open for weeks or months, leaving patients at risk of infection, hospitalization, and amputation.

A research paper by scientists from Tsinghua University presented a novel text sequence stimulation paradigm that combines periodic visual stimulation with orthographic information and elicits distinct occipital and occipitotemporal scalp response patterns relative to conventional brightness flicker.

The new research paper, published on Jun. 15 in the journal Cyborg and Bionic Systems, developed a novel text sequence stimulation paradigm that dramatically improves user comfort without sacrificing performance.

A review paper by scientists from Shenzhen University compared 2 complementary technology paths: “tethered” catheter systems designed for rapid and operator-controlled reopening of large vessels, and “untethered” micro/nanoscale systems, including injectable carrier-based platforms and actively actuated micro/nanorobots, that can be actuated and guided by magnetic, ultrasound, or light energy to seek, penetrate, and disrupt clots at the microscale.

The new research paper, published on Jun. 5 in the journal Cyborg and Bionic Systems, compared two complementary technology paths – “tethered” catheter systems and “untethered” micro/nanorobotic platforms – and outlines how their integration under imaging guidance could transform thrombus recanalization.

Underwater landslides are a destructive force, putting vital submarine infrastructure at serious risk and can even generate damaging tsunamis. By analyzing research completed from 2000 to 2025, scientists tracked this phenomenon to better understand what triggers the landslides, how they move and generate tsunamis, and the dangers they pose.

A novel sprayable nanozyme dressing developed by Chinese researchers effectively treats aerobic vaginitis by combining antibacterial, anti-inflammatory, and microbiome-regulating properties. Tested in mice, the dressing not only alleviated infection and inflammation but also restored reproductive function and pregnancy rates, offering a promising non-antibiotic strategy for gynecological care.

Electronic devices capable of perceiving and responding to environmental changes are essential for applications in human–machine interaction, monitoring systems, and robotics. However, most existing devices suffer from the separation of sensing and actuation, leading to complex integration and limited responsiveness. In this study, the researchers introduce an intelligent thermoelectric device inspired by the interplay between sensory and muscle cells in sea anemones. The device seamlessly combines multimodal sensing with autonomous thermal actuation, enabling a closed-loop sensory–motor reflex. It demonstrates excellent temperature sensitivity (0.2 ℃) and pressure resolution (0.03 mm), owing to its three-dimensional architecture and hierarchical conductive network. Molecular dynamics simulations show that its dynamic hydrogen-bonding network enhances stress dissipation and interfacial adhesion, resulting in exceptional mechanical stability over 140,000 cycles. Furthermore, the device exhibits thermal self-adaptation, actively initiating a protection mechanism through thermoresponsive deformation to avoid high-temperature stimuli, with an adjustable actuation threshold. This work represents a significant advancement toward intelligent electronics capable of real-time decision-making and active environmental interaction.

Harvesting low-grade heat from both human metabolism and environmental waste through thermoelectric fabrics offers a sustainable pathway for wearable power generation. However, a critical challenge exists in establishing substantial temperature differentials for continuous thermoelectric generation while maintaining physiologically comfortable skin temperatures in dynamically variable environments.

With the quick development of flexible electronic devices such as foldable phones and wearable sensors, the demand for high-performance flexible transparent conductors (TCs) surges. Thin films of indium tin oxide (ITO), the traditional TCs, are increasingly constrained by their brittleness, limited indium sources, and high fabrication cost. The researchers at Hunan University and Xiamen University, China, have developed a supersaturation modulation strategy, enabling the efficient synthesis of ultra-long silver nanowires (Ag NWs) with high yield. The synthesized Ag NWs exhibit exceptional electrical conductivity, optical transparency, and mechanical flexibility, offering a promising alternative to ITO for next-generation TCs.
