On this programme, we first look at the latest Global Innovation Index as the Shenzhen-Hong Kong-Guangzhou cluster retains its top spot in 2026 for the second-straight year.
Then, we hear from a doctor on why members of the public who have had sex should undergo HIV antibody testing at least once to prevent HIV transmission in the community.
After the break, a scholar from the Hong Kong University of Science and Technology will tell us how he and his team have developed an innovative testing platform that could transform highly sensitive nucleic acid testing from a laboratory-based procedure into a simple, single-step test that can be performed at home.
And to wrap up the show, we learned why the United Nations General Assembly has backed a resolution spearheaded by several African countries to adopt a map that makes their continent bigger while shrinking North America and Europe.
