Recycled rubber granulate made from used car tires is widely promoted as a sustainable material for playgrounds, sports fields, and running tracks. However, new research suggests that the smallest rubber particles may release harmful chemicals into the environment and pose risks to soil organisms, plants, and potentially human health.

In an innovative study, researchers apply cross-modal interaction and selection mechanisms to robotic visual–inertial trajectory localization. This approach not only improves localization accuracy for robots under GNSS-denied conditions but also effectively enhances the robustness of the algorithm in complex environments.

Researchers at the Ningbo Institute of Materials Technology and Engineering (NIMTE) of the Chinese Academy of Sciences (CAS) have made an important breakthrough by developing a three-dimensional (3D) electrical imaging technique that directly reveals how defect passivation treatments work in perovskite films.

Beijing’s metro could quietly carry freight during off-peak hours without new tunnels, a joint timetable–rolling-stock model shows. Flexible train compositions and selective skip-stop patterns cut operating costs by up to 25% while keeping passenger delays minimal.

A new potassium-containing copper-zeolite catalyst, Cu-SSZ-39-K, enables major progress in low-temperature diesel NO_xemission control. Its higher fraction of Al in 8-memberedringspromotes the formation of more active [Cu(OH)]⁺-Z species, nearly doubling NO_x conversion at 150-225°C compared with conventional Cu-SSZ-39. The catalyst also maintains highly stable and excellent performance after 800°C hydrothermal ageing.With its enhanced activity and high-yield synthesis, Cu-SSZ-39-K offers a scalable route to cleaner diesel emissions.

Researchers have developed a low-cost visible light communication (VLC) system using commercially available hardware that enables stable data transmission even under strong ambient light. By implementing a newly designed 8B13B coding scheme on an FPGA and interfacing it with a Raspberry Pi, the team achieved reliable outdoor VLC at data rates of up to 3.48 Mbit/s over distances of several meters. The approach addresses key challenges in VLC, including pulse distortion and sunlight interference, and offers a practical path toward intelligent transportation system (ITS) applications.

Scientists have created a groundbreaking, fully implantable neurostimulator made entirely of soft hydrogel to treat inflammatory bowel disease (IBD). Unlike traditional rigid and wired implants, this wireless device gently wraps around the splenic nerve. It receives power through the skin to deliver electrical pulses that calm gut inflammation by rebalancing the immune system. In animal studies, the device significantly alleviated colitis symptoms without causing scar tissue formation, paving the way for a new class of soft, bioelectronic therapies for chronic diseases.
