With coronavirus outbreaks at different stages around the world, in many countries lockdowns are being carefully eased off while urging citizens to keep on practicing the social distancing rules. Singapore is trying a new way of carrying it out—a robot dog.

The government has arranged Spot, a yellow and black robotic dog made by Boston Dynamics Company, at one local park. The same robot has been previously seen dancing to hit song “Uptown Funk.”However, 2020 is an extremely difficult year and the company is trying to assist the national coronavirus-control effort. In turn, the job has been handed over to Spot.

The four-legged robot dog patrols(巡查) the park and broadcasts a pre-recorded message to encourage visitors to observe safe distancing measures. As it walks around the park, the dog says in a female voice, “Let's keep Singapore healthy. For your own safety and for those around you, please stand at least one meter apart. Thank you.”

Spot is one of the world's most advanced robots and unlike wheeled robots, it is capable of going pretty much anywhere a dog can go and can walk up to three miles per hour over different areas, making it ideal for operation in public parks and gardens. Furthermore, it is remotely controlled and has cameras with 360-degree vision and analytic tools to scan the surroundings and help officials estimate the number of people gathering in the park.

For now, the pilot project is currently set to run in a limited trial for two weeks at one park during off-peak(非高峰)hours. But if all goes well, authorities will consider expanding the program to improve enforcement(强制)of social distance throughout on Singapore

Spot is also being used in other ways during the public health crisis beyond just patrolling a park. The government says it's also using Spot in another capacity- at a local isolation facility where the robot helps bring medicine to patients.

For the first time, the World Health Organization has included Traditional Chinese Medicine (TCM) in its globally influential medical compendium(手册), according to an international science journal.

An article published by Nature on Wednesday said that TCM will be included in the latest version of the International Classification of Diseases (ICD)set to be released next year. Starting from the 1800s, the ICD has been improved and published in a series of editions,reflecting the advances in health and medical science over time. It serves as the foundation for the identification of global health trends, and the international standard for diseases and health conditions.

The latest ICD is based largely on the work of the International Classification of Traditional Medicine   (ICTM) project's experts from around the world. These experts had been working on traditional medicine research and practices for years.

China has been promoting the modernization of TCM and pushing for TCM to gain acceptance worldwide. Tu Youyou, a Chinese expert focusing on the scientific study of drugs and medicines, was awarded the Nobel Prize in Medicine in 2015 for her research in TCM. Her discovery has saved millions of lives in developing countries in South Asia, Africa and South America. TCM is sure to grow in popularity globally.

Though the application of traditional Chinese medicine, acupuncture(针灸) and other traditional medical practices has been on the rise, there's still a shortage of global classification and terminology(术语) tools for traditional medicine, according to officials of the WHO.

“The decision is to promote the safe and effective use of traditional medicine by regulating, researching and combining traditional medicine products, practitioners and practice into health systems, where appropriate," the WHO was quoted as saying by Nature.

Education appears to protect older adults especially women, against memory loss, according to a study by investigators at Georgetown University Medical Center.

The Study tested declarative memory in 704 older adults (58-98 years of age). Declarative memory refers to our ability to remember events facts and words, such as where you put your keys or the name of that new neighbor. The investigators found that their memory performance became progressively worse with aging. However, more years of early-life education countered these Tosses, especially in women.

For example, the declarative memory abilities of an 80-year-old woman with a bachelor’s degree would be as good as those of a 60-year-old woman with a high school education. So, four extra years of education make up for the memory losses from 20 years of aging.

“Simply said, learning brings about learning.” says the study’s senior investigator, Michael Unman. “Since learning new information in declarative memory is easier if it is related to knowledge we already have, more knowledge from more education should result in better memory abilities, even years later,” adds the study’s lead author, Jana Reifegerste.

“Evidence suggests that girls often have better declarative memory than boys, so education may lead to greater knowledge gains in girls,” says Ullman. “Education may thus particularly benefit memory abilities in women, even years later in old age.”

The study tested individuals in a non-Western population. Participants varied in the number of years of education, from none at all to graduate studies. Future research is needed to test whether the findings generalize to other populations, Ullman says.

“These findings may be important, especially considering the rapidly aging population globally,” Reifegerste says. “The results argue for further efforts to increase access to education.”

“Education has also been found to delay the beginning of Alzheimer’s disease,” Ullman says. “We believe that our findings may shed light on why this occurs.”
