The Shenzhou XVI mission crew returned to Earth on Tuesday morning, concluding a historic, five-month mission.


The Shenzhou XVI spacecraft's reentry capsule, carrying the three astronauts — mission commander Major General Jing Haipeng, Colonel Zhu Yangzhu and Professor Gui Haichao — touched down at 8:11 am at the Dongfeng Landing Site in Gobi Desert in the Inner Mongolia autonomous region.
神舟十六号载人飞船的返回舱载着三名宇航员——指令长景海鹏 、航天飞行工程师朱杨柱、载荷专家桂海潮,于当日上午8点11分在内蒙古的沙漠戈壁区东风着陆场成功着陆。


Following safety checks outside the capsule, ground recovery personnel opened the hatch of the bell-shaped vehicle and conducted a preliminary examination of the astronauts' condition.


Sitting inside the capsule, Jing told ground controllers in Beijing via radio that his team had landed safely and were "feeling pretty good".


Jing's team entered the Tiangong station on May 30.


Their journey was China's 11th manned spaceflight and the fifth crewed mission to the Tiangong space station. The journey was the debut flight of China's third generation of astronauts.


For the next six months, Tiangong will be manned by the Shenzhou XVII crew, who arrived at the space station on Thursday evening.


> Getting less slow-wave sleep as you age may increase your risk of dementia



Loss of slow-wave sleep as you age may increase your risk of developing dementia, according to a new study.


"We found that aging was associated with a decline in the amount of the deepest stages of sleep, known as slow wave sleep,” said Matthew P. Pase, senior author of the study published Monday in the journal JAMA Neurology, via email. Pase is an associate professor of psychology and neurology at Monash University in Australia.


"We then found that persons with greater declines in slow wave sleep over time had a higher risk of getting dementia over the next 17 years of follow-up,” said Pase via email.


Slow-wave sleep is the third stage of sleep, which is important for brain health.


During this stage, the body removes unwanted, or potentially harmful, materials from the brain — including beta-amyloid protein, a hallmark sign of Alzheimer’s disease.


The researchers studied 346 people who were aged 69 on average and had participated in the Framingham Heart Study and completed two overnight sleep studies — one between 1995 and 1998 and the second between 1998 and 2001 — during which their sleep was monitored.


Launched by the US National Heart, Lung and Blood Institute in 1948, the Framingham Heart Study identifies common factors contributing to cardiovascular disease.


The authors also investigated whether any changes in the amount of slow-wave sleep that participants got was associated with developing dementia up to 17 years after they completed the sleep studies.


By that time, 52 participants had been diagnosed with dementia.


Each percentage decrease in slow-wave sleep per year was linked with a 27% increased risk of developing dementia and a 32% higher risk of Alzheimer’s disease dementia.


The rate of slow-wave sleep loss accelerated from age 60, peaked from ages 75 to 80 and slowed afterward.


Those who experienced declines in this deep sleep were more likely to have cardiovascular disease, take medications that affect sleep and carry a gene that makes people more at risk for Alzheimer’s (the APOE ε4 allele).
深睡眠减少的人群更可能患上心血管疾病,以及服用影响睡眠的药物,携带阿尔茨海默病高风险基因APOE ε4 allele的人也更可能出现深睡眠减少。
