Nagoya University researchers have developed gallium-doped zinc oxide (GZO) nanosheets that may enhance camera-resolution in compact devices such as smartphones and medical endoscopes. These nanosheets enable a single pixel to detect the intensity of red, green, and blue (RGB) light while remaining nearly transparent, unlike conventional optical sensors. They are ultrathin, lightweight, and can withstand temperatures up to 400 degrees Celsius, making them suitable for extreme environments such as space hardware and automotive systems.

Sub-Neptunes are among the most common type of close-in planets found in our Galaxy, yet their bulk composition remains largely uncertain; H-rich envelopes overlaying rocky cores, volatile-rich planets, and carbon-rich interiors all remain viable configurations for members of this population. Atmospheric characterization has been proposed as a means of distinguishing between these scenarios, but growing evidence suggests that sub-Neptunes may host molten atmosphere–mantle interfaces that could alter the composition of their atmosphere

A compact 300-GHz-band 4×4 bi-directional phased-array transceiver in 65-nm CMOS has been developed, as reported by researchers from Institute of Science Tokyo. While free space path loss is a significant challenge for the 300-GHz-band in wireless systems, this development can mitigate the problem, resulting in significant advancement in 6G wireless communication. 

Chinese scientists have identified five major fundamental scientific questions for extreme complex geological disaster chains: “disaster gestation through multi-sphere interactions, disaster regulation by multi-interface control, disaster propulsion by multi-dynamic coupling, disaster initiation by extreme events, and disaster amplification through multi-disaster chain interactions.” They further reveal the core characteristics of disaster chains from the three dimensions of time, space, and human activities, and construct a coherent “mechanism–prediction–prevention and control” research framework.
