Researchers discover latitude- and regolith-dependent distribution of lunar surface water

Chinese Academy of Sciences Headquarters
Peer-Reviewed Publication

A research team from the Institute of Geology and Geophysics of the Chinese Academy of Sciences (IGGCAS) has found that lunar soil samples brought back by China's Chang'e-6 mission (collected from the lunar farside) contain high concentrations of OH/H₂O and low deuterium-to-hydrogen (D/H) ratios. These characteristics align with lunar water originating from the solar wind, the team noted.

New study reveals southern ocean’s winter CO₂ outgassing underestimated by 40%

Chinese Academy of Sciences Headquarters
Peer-Reviewed Publication

A collaborative research team has discovered that the Southern Ocean releases substantially more carbon dioxide (CO₂) during the dark austral winter than previously thought. Their new study reveals that this winter outgassing has been underestimated by up to 40%.

Enhancing ocean wind observation accuracy: New rain correction approach for FY-3E WindRAD

Institute of Atmospheric Physics, Chinese Academy of Sciences
Peer-Reviewed Publication

A recent collaborative study led to the development of an innovative rain conceptual model using dual-frequency measurements from the WindRAD instrument aboard China’s FengYun-3E (FY-3E) satellite to quantify and correct rain-induced errors in wind measurements.

Massively parallel implementation of nonlinear functions using an optical processor

Light Publishing Center, Changchun Institute of Optics, Fine Mechanics And Physics, CAS
Peer-Reviewed Publication

UCLA researchers demonstrate diffractive optical processors as universal nonlinear function approximators using linear materials. They realized arbitrary sets of bandlimited nonlinear functions, including multi-variate and optically-cascadable complex-valued functions, as well as some of the activation functions used in neural networks. Researchers further demonstrated, through optical simulations, the parallel computation of one million distinct nonlinear functions, executed at wavelength-scale output density. An experimental validation was also demonstrated by executing tens of distinct nonlinear functions simultaneously.

"Can it?" vs. "did it?"— new study reveals the complex role of the Asian summer monsoon in the 2021 Pacific Northwest heatwave

Institute of Atmospheric Physics, Chinese Academy of Sciences
Peer-Reviewed Publication

A new study warns against oversimplifying the causes of extreme weather. While the Asian monsoon can influence North American climate, researchers found its usual effect is to cool the Pacific Northwest. However, during the 2021 heatwave, a uniquely strong jet stream acted as an "atmospheric waveguide," redirecting the monsoon's energy and amplifying the heat. This shows that a factor's general influence ("can it?") can differ from its role in a specific event ("did it?"), highlighting the need for detailed, case-by-case analysis.
