Researchers at NYU Abu Dhabi (NYUAD) have developed an innovative tool that enhances surgeons' ability to detect and remove cancer cells during cryosurgery, a procedure that uses extreme cold to destroy tumors. This breakthrough technology involves a specialized nanoscale material that illuminates cancer cells under freezing conditions, making them easier to distinguish from healthy tissue and improving surgical precision.

In a new study published in Engineering, researchers have developed an analytical framework integrating ecological security assessment, prediction, and zoning management. Using the Daqing River Basin as a case study, they found its ecological security improved from 2000~2020, but with spatial differences. The framework offers valuable insights for similar regions and sets a basis for further ecological security research.

For decades, scientists have relied on electrodes and dyes to track the electrical activity of living cells. Now, UC San Diego engineers have discovered that quantum materials just a single atom thick can do the job with high speed and resolution—using only light.

Scientists from Southeast University and Guangzhou University have developed a new design paradigm for reconfigurable intelligent surfaces (RISs). Published in Engineering, this approach addresses challenges in traditional RIS design, such as high data costs and inefficient pattern design. It combines a novel topological representation method with a separate design architecture, offering a more efficient way to design RISs for applications in wireless communication and sensing.

Customized 3D-printed medical implants are becoming more common, and a new study has taken this technology to the next level. Researchers at Naton Biotechnology have developed the world’s first laser 3D-printed total knee implant, which has received official approval from China’s National Medical Products Administration as an innovative medical device.

The study focused on improving the strength and consistency of cobalt-chromium-molybdenum (CoCrMo) alloy implants made using laser powder bed fusion (LPBF), a 3D printing process. The team discovered and corrected inconsistencies in the structure of the material by optimizing heat treatment, ensuring the final implants are stronger, more reliable, and safer for patients.

This research provides key insights into how 3D printing affects metal implants and lays the foundation for better quality control in orthopedic manufacturing, helping to advance the future of customized medical implants.

This research was led by Professor Changhui Song from South China University of Technology and Professor Jia-Kuo Yu from Beijing Tsinghua Changgung Hospital as co-corresponding authors. The study was conducted in collaboration with Senior Engineer Renyao Li from Naton Biotechnology (Beijing) Co., Ltd and other members of the team.
