Chinese researchers have developed an on-chip integrated polarization photodetector (pol-PD), drawing inspiration from the unique polarization vision of desert ants. The study, recently published in the journal Science Advances, was conducted by researchers from the Technical Institute of Physics and Chemistry (TIPC) of the Chinese Academy of Sciences.
Chinese scientists have discovered dozens of human fossils dating back 300,000 years, which are the earliest ones found in East Asia in terms of the evolution process towards Homo sapiens, the species to which all modern human beings belong. The human fossils, along with a large number of fossilized animal bones and stone tools, have been unearthed at the Hualongdong site in Dongzhi County, east China's Anhui Province.
Chinese scientists have successfully assembled the chromosome-level genome of the rare Tibetan antelope, aiming to decode the secrets behind their survival at high altitudes. The Tibetan antelope plays a crucial role in biodiversity conservation on the Qinghai-Xizang Plateau. "So, this achievement not only represents a technical upgrade in the field of Tibetan antelope genetics research, but also provides an important genetic foundation for the conservation of plateau biodiversity," said Zhang Tongzuo, a researcher at the the Northwest Institute of Plateau Biology under the Chinese Academy of Sciences.
Several observatories in China have captured rare images of a falling near-Earth asteroid, formally designated as 2024 XA1. The images, along with the observation results of foreign observatories on the asteroid, mark the 11th successful early warning of an asteroid impacting Earth, and the 4th such prediction of 2024. The asteroid has an estimated diameter of between 75 centimeters and one meter. It was first discovered by a University of Arizona telescope at 5:55 a.m. (UTC) on Dec. 3.
Building on mature big data and artificial intelligence technologies, Chinese scientists have developed a targeted system for land degradation management on the Arabian Peninsula, which can be used to support governance decisions in the region, an expert said.
A collaborative study between Chinese and U.S. scientists has revealed that horned dinosaurs experienced a decline in intelligence, hearing and sense of smell as they evolved to larger sizes over 100 million years. By delving into the morphology of the cranial cavities of early ceratopsian dinosaurs, the scientists have shed light on the behavior of these ancient creatures.
