Living fungus-based building material repairs itself for over a month

Cell Press
Peer-Reviewed Publication

Engineers have developed a building material that uses the root-like mycelium of a fungus and bacteria cells. Their results, publishing April 16 in the Cell Press journal Cell Reports Physical Science, show that this material—which is manufactured with living cells at low temperatures—is capable of self-repairing and could eventually offer a sustainable alternative for high-emission building materials like concrete.

From disorder to order: scientists rejuvenate aging batteries

Chinese Academy of Sciences Headquarters
Peer-Reviewed Publication

A team of scientists led by Prof. LIU Zhaoping at the Ningbo Institute of Materials Technology and Engineering (NIMTE) of the Chinese Academy of Sciences, in collaboration with researchers from the University of Chicago and other institutions, has developed zero thermal expansion (ZTE) materials. This innovation has achieved nearly 100% voltage recovery in aging lithium-ion batteries (LIBs), as detailed in a study published in Nature.

A compact, mid-infrared pulse generator

Harvard John A. Paulson School of Engineering and Applied Sciences
Peer-Reviewed Publication

Physicists in the Harvard John A. Paulson School of Engineering and Applied Sciences have created a compact laser that emits extremely bright, short pulses of light in a useful but difficult-to-achieve wavelength range, packing the performance of larger photonic devices onto a single chip.

Pushing the limits of brain imaging: A new tool for targeted delivery of imaging agents and drugs

SPIE--International Society for Optics and Photonics
Peer-Reviewed Publication

Repeated administration of imaging agents to the mouse brain during live multiphoton microscopy is enabled by a newly developed delivery system. This low-profile cannula, implanted at a shallow angle, preserves optical access for high-resolution imaging while allowing direct infusion of compounds. The new approach was validated through experiments tracking fluorescent markers, degenerating neurons in Alzheimer's disease mice, and measuring brain tissue oxygen levels over time. This advancement promises to enhance longitudinal brain imaging studies, providing valuable insights into brain function and disease progression.

ECNU Review of Education unveils the evolution of LLMs in intelligent Chinese composition tutoring

ECNU Review of Education
Peer-Reviewed Publication

Grading Chinese compositions is often time-consuming and inconsistent. A recent study explores the ELion system, a collaboration between East China Normal University and Microsoft Research Asia, developed to enhance automated essay scoring and feedback generation. It examines the system’s evolution through multiple stages, integrating AI-driven assessment tools. By addressing key challenges in composition grading, this study provides insights into the transformative potential of AI in Chinese language education.
