South China Morning Post published this video item, entitled “Magnetic-slime robot created by Hong Kong researchers” – below is their description.
A magnetic slime robot has been developed by researchers at the Chinese University of Hong Kong in the hope of using it in surgery. The slime contains magnetic particles which can be manipulated when external magnets are applied to it. Although the magnetic particles are toxic, a protective coating is being developed that may soon make it safe to use in the human digestive system. One practical application would be to retrieve accidentally-swallowed objects.

In This Story: Hong Kong
Hong Kong, officially the Hong Kong Special Administrative Region of the People’s Republic of China (HKSAR), is a metropolitan area and special administrative region of the People’s Republic of China on the eastern Pearl River Delta of the South China Sea. With over 7.5 million residents of various nationalities in a 1,104-square-kilometre (426 sq mi) territory, Hong Kong is one of the most densely populated places in the world.
Hong Kong became a colony of the British Empire after the Qing Empire ceded Hong Kong Island at the end of the First Opium War in 1842. The colony expanded to the Kowloon Peninsula in 1860 after the Second Opium War and was further extended when Britain obtained a 99-year lease of the New Territories in 1898. The whole territory was transferred to China in 1997. As a special administrative region, Hong Kong maintains separate governing and economic systems from that of mainland China under the principle of “one country, two systems”.
