A PKU-ZJU study reports the Spatial Harmonic-extended Generalized Snell's Law. This work shifts metasurface engineering from single- to multi-harmonic control, from local resonance to global symmetry, and from trial-and-error to physics-driven design. #Nanophotonics

A multinational PKU-led team found that these human activities and warming seas are speeding up mercury release from continental shelf sediments, threatening marine life and humans. Historical mercury buried for decades could be reactivated and re-enter the food chain, Dr. Liu Maodian warns.

🌊 “Continental shelves act like the ocean's kidney, filtering toxic mercury, but trawling and dredging are like a surgical knife,” said #PekingUniversity Prof. Wang Xuejun.

“A dramatic difference in temperature between the near and far side of the mantle has long been hypothesised, but our study provides the first evidence using real samples,” said geoscientist Li Yang of #PekingUniversity & UCL, who co-led the study published in Nature Geoscience. @uclnews.bsky.social

🌗The Moon has two faces—and the difference runs deeper than we ever knew.

Analyzing historic samples from Chang’e-6, PKU researchers and collaborators found that the lunar farside’s interior is about 100°C cooler than the nearside.

#Emoji in Crisis Communication: A Cultural Twist 🤔

A new #PKUResearch led by Soojin Roh reveals how emojis shape public response in corporate crises. In China, they reduce anger and improve company image, but in the US, they often backfire, especially when used by CEOs.

Accurate lesion segmentation is key for diagnosis and treatment, but labeled data are scarce.

A #PKUResearch team developed a semi-supervised, multi-modal method that enables high-precision automatic segmentation of complex tumors with only a few labeled scans.
