In the azure waters of the Caroline Seamounts at a depth of 1240 meters, a red-orange dumbo octopus flutters through the water with its fins as wings.

A new study published by The Australian National University experts in Nature Astronomy reveals that stars in close binary systems – pairs of stars orbiting each other at close range – can exhibit unexpectedly high levels of magnetic activity. In this study, LAMOST has played a significant role.

Regarding to the precise measurement and control of time synchronization and carrier-envelope phase difference (ΔCEP) between pulses, a concise optical method based on the phase retrieval of spectral interference and quadratic function symmetry axis was proposed, which could fit to simultaneously measure the time synchronization and ΔCEP between few-cycle pulses. The control precision of our coherent beam combining system can achieve a time delay stability within 42 as and ΔCEP measurement precision of 40 mrad, enabling a maximum combining efficiency of 98.5%. This method can effectively improve the performance and stability of coherent beam combining systems for few-cycle lasers, which will facilitate the obtaining of high-quality few-cycle lasers with high energy.

The near-inertial internal wave is a significant energy source for deep-sea mixing. However, the energy source of deep near-inertial internal waves remains largely unknown. Recently, the research team led by Prof. WANG Fan from the Institute of Oceanology of the Chinese Academy of Sciences (IOCAS) has made new progress in the study of the generation mechanism of deep near-inertial kinetic energy.

researchers have discovered the deepest,most extensive chemosynthesis-based communities of organisms during an expedition to the Kuril-Kamchatka Trench and the western Aleutian Trench,according to a recent research article published in Nature.

Recently, the Free-Electron Laser (FEL) team at the Shanghai Advanced Research Institute (SARI), Chinese Academy of Sciences experimentally demonstrated their independently proposed concept of Direct-Amplification Enabled Harmonic Generation Free-Electron Laser (DEHG-FEL) for the first time, and successfully achieved its lasing and stable operation. This marks a key milestone toward realizing X-ray FEL sources operating at megahertz (MHz) repetition rates. The results were published in Physical Review Letters and were highlighted as an Editors’ Suggestion.

All-polymer solar cells (APSCs) possess excellent material flexibility, solution processability, and thermal stability, offering great potential for lightweight and large-area printed applications in wearable and stretchable devices. A critical factor in achieving high performance is the optimization of active layer morphology, especially the regulation of crystallization and phase separation of the donor. However, the real-time morphological evolution during post-treatment processes such as solvent vapor annealing (SVA) has remained unclear.

Researchers at the Institute of Modern Physics of the Chinese Academy of Sciences have recently confirmed that the fully stripped heavy ion-atom collision is an effective way to produce heavy hollow atoms in high yield

Recognizing these numbers helps scientists better understand the structure of nuclei.

A research team led by Prof. HUANG Chengdong from the University of Science and Technology of China, users of the Steady High Magnetic Field Facility (SHMFF), has uncovered a previously unknown mechanism by which intrinsically disordered regions (IDRs) remotely regulate protein function.
