A new study has revealed that chronic exposure to artificial light at night can trigger depression-like behaviors by activating a specific neural pathway in the brain. The study, conducted on tree shrews -- diurnal mammals genetically close to primates, offers critical insights into how nighttime light may disrupt mood regulation. It has been published in the journal Proceedings of the National Academy of Sciences.
A group of Chinese researchers has developed a cocktail hydrogel that can promote the regeneration of the neurovascular unit and repair damaged brain tissue, providing an important theoretical basis and novel strategies for cell replacement therapy for cortical brain injuries. Researchers at the Chinese Academy of Sciences' Guangzhou Institutes of Biomedicine and Health developed the new cocktail hydrogel, which exhibits a three-dimensional scaffold structure with biomimetic properties.
For fifteen years, scientists had grappled with a fundamental mystery about Denisovans, human beings' ancient cousins. They wondered what Denisovans looked liked. The answer to this question held special significance for East Asian and Oceanian communities, who carry distinct traces of Denisovan DNA. Now, two landmark studies published Wednesday in Science and Cell, respectively, present molecular evidence confirming that a remarkably preserved 146,000-year-old hominin skull, discovered near Harbin in northeast China, represents a definitive Denisovan fossil.
A new study has unveiled the key mechanism for alpine grassland carbon sink on the Qinghai-Tibet Plateau in western China, providing scientific underpinning for ecological security. The study, conducted by researchers from the Northwest Institute of Plateau Biology (NWIPB), under the Chinese Academy of Sciences, has been published in the journal Agricultural and Forest Meteorology.
China has released its most detailed map yet of grassland vegetation on the Qinghai-Tibet Plateau, using a scale of 1:500,000. The map, developed by a team led by Wang Yanfen, a professor at the University of Chinese Academy of Sciences (UCAS), was officially unveiled on Tuesday during an academic seminar on grassland vegetation mapping.
Scientists from northwest China's Xinjiang Uygur Autonomous Region are working to help African countries transform the sandy regions into greener, arable land with more trees and productive agricultural practices. As June 17 marks the World Day to Combat Desertification and Drought, these efforts are gaining increased attention and are expected to yield fruitful outcomes.
