Mice exhibit altruistic rescue behavior driven by oxytocin

Chinese Academy of Sciences Headquarters
Peer-Reviewed Publication

Researchers led by Dr. HU Li from the Institute of Psychology of the Chinese Academy of Sciences and Dr. CHEN Zhoufeng from Washington University School of Medicine and the Shenzhen Medical Academy of Research and Translation have found that mice can instinctively exhibit rescue-like behavior toward anesthetized conspecifics—without any prior training or external rewards. The study, published in PNAS, offers compelling evidence that prosocial behavior may be deeply rooted in biology, extending even to small mammals like mice.

Peer-Reviewed Publication

Free electron lasers have unique advantages of high power, wide frequency tunablility and et al, however, they face challenge in narrowing the spectral linewidth. Scientists in China proposed and realized the pump-induced stimulated superradiant Smith-Purcell radiation (PIS-SPR) and achieved an ultra-narrow spectral linewidth of 0.3 kHz at ~0.3 THz in a compact device. The mechanism and technique provides a way to further narrow the spectral linewidth of free electron radiation and broaden its applications.
