BEIJING, July 25 (Xinhua) — The following are the highlights of China’s science news from the past week:
LINK BETWEEN SLEEP, ALZHEIMER’S
A Chinese study has found that people who go to bed around 10:00 p.m. and sleep about six to seven hours a night have a lower risk of developing Alzheimer’s disease.
The researchers from Fudan University and Qingdao University reported in the journal Alzheimer’s & Dementia that they found a U-shaped relation between nocturnal sleep habits and the level of amyloid-beta deposition in cerebrospinal fluid.
NEW FINDINGS ON DARK ENERGY
Chinese scientists have reported new findings based on astronomical observations, providing novel evidence for the existence of dark energy in the cosmos.
The studies were released on Monday by the international collaboration of the eBOSS, the biggest ongoing galaxy survey in the world.
Based on the eBOSS observations, astronomers at the National Astronomical Observatories of the Chinese Academy of Sciences (NAOC) measured the history of cosmic expansion and structural growth in a huge volume in a past universe that was never probed before, corresponding to a distance range of between 0.7 and 1.8 billion light years away.
AI RESEARCH FOR COVID-19 PATIENTS
Chinese researchers are now using artificial intelligence (AI) technologies to predict COVID-19 patients’ risk of developing critical illnesses, which will facilitate the early triage of these patients.
Based on the data of 1,590 patients from 575 medical centers, researchers developed a deep learning-based survival model that can predict the risk of COVID-19 patients developing critical illnesses within five, 10, and 30 days, based on their clinical characteristics at admission.
More than 70 percent of monitored lakes in China witnessed increasing water transparency between 2000 and 2018, which means that lakes in the country have became clearer, according to a new study.
The research was based on big data from remote sensing and was jointly conducted by experts from China, Italy, the United States and Britain. It analyzed monitoring results of a total of 412 lakes, covering most lakes with a water area of more than 20 square km. Enditem
