New machine learning framework enhances precision and efficiency in metal 3D printing, advancing sustainable manufacturing

University of Toronto Faculty of Applied Science & Engineering
Peer-Reviewed Publication

Researchers at University of Toronto Engineering, led by Professor Yu Zou, are leveraging machine learning to improve additive manufacturing, also commonly known as 3D printing. In a new paper, published in the journal of Additive Manufacturing, the team introduces a new framework they’ve dubbed the Accurate Inverse process optimization framework in laser Directed Energy Deposition (AIDED).

The new AIDED framework optimizes laser 3D printing to enhance the accuracy and robustness of the finished product. This advancement aims to produce higher quality metal parts for industries, such as aerospace, automotive, nuclear and health care, by predicting how the metal will melt and solidify to find optimal printing conditions.

Unlocking dopamine’s hidden role: Protective modification of Tau revealed

Peking University
Peer-Reviewed Publication

Peking University, March 19, 2025: The research group led by Prof. Wang Chu from the College of Chemistry and Molecular Engineering at Peking University published a research article entitled “Quantitative Chemoproteomics Reveals Dopamine’s Protective Modification of Tau” in Nature Chemical Biology (DOI:10.1038/s41589-025-01849-9). Using a novel quantitative chemoproteomic strategy, the team uncovered a protective role of dopamine (DA) in regulating the function of the microtubule-associated protein Tau. This discovery deepens our understanding of dopamine’s physiological and pathological roles in the human brain.

Breakthrough in deep ultraviolet laser technology

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

Researchers from the Chinese Academy of Sciences achieved a breakthrough in deep ultraviolet (DUV) laser technology by developing a compact, solid-state laser system that generates 193-nm coherent light. This system, operating at a repetition rate of 6 kHz, utilizes a Yb:YAG crystal amplifier and a combination of fourth-harmonic generation and optical parametric amplification. The resulting 193-nm laser, with an average power of 70 milliwatts and a linewidth of less than 880 MHz, is the highest power achieved using LBO crystals. Additionally, the team successfully generated a 193-nm vortex beam, marking the first demonstration of such a beam from a solid-state laser. This advancement holds significant potential for applications in semiconductor lithography, wafer processing, defect inspection, quantum communication, and optical micromanipulation.

Device enables direct communication among multiple quantum processors

Massachusetts Institute of Technology
Peer-Reviewed Publication

MIT researchers developed a scalable interconnect that facilitates all-to-all communication among many quantum processor modules by enabling each to send and receive quantum information on demand in a user-specified direction. They used the interconnect to demonstrate remote entanglement, a type of correlation that is key to creating a powerful, distributed network of quantum processors.

Breakthrough in rapid super-resolution imaging of multiple organelles in live cells

Peking University
Peer-Reviewed Publication

Peking University, April 2, 2025: A team from Peking University’s College of Future Technology, led by Professor Xi Peng, in collaboration with Professor Jin Dayong at the Eastern Institute of Technology, has achieved a major breakthrough in imaging 15 cellular structures simultaneously by using lipid membrane probes to label all membrane-bound organelles, combined with dual-color spinning-disk confocal microscopy and deep learning. Their study, titled "Fast Segmentation and Multiplexing Imaging of Organelles in Live Cells", published in Nature Communications (DOI:10.1038/s41467-025-57877-5), utilizes Nile Red dye, spinning-disk confocal microscopy, and deep learning to overcome limitations in traditional fluorescent imaging.

Nanotech-induced cooling improves crop yields in arid climates

King Abdullah University of Science & Technology (KAUST)
Peer-Reviewed Publication

cientists at King Abdullah University of Science and Technology (KAUST) have developed and combined a new nanoplastic and biodegradable mulch to passively cool greenhouses in hot, arid climates like those in the Middle East. Applying their technology, they lowered temperatures of miniature greenhouses by 25 degrees Celsius and increased crop yields of Chinese cabbage by nearly 200%.
