About GYSTB 2020

The Finals of the Global Youth Science and Technology Bowl 2020 (GYSTB 2020) was successfully held online on August 1 2020 (Sat).

The competition attracted a total of 122 teams from 22 countries and regions. With 92 shortlisted secondary school teams from around the world, this was an exciting event, with presentations of innovative science and technology solutions to tackle every day challenges.

A "Study on the Anti-reflux ability of Chinese Yam using Novel Gastro-oesophageal Model " by Hong Kong's Heep Yunn School took the Gold Prize in the Biology and Chemistry category. The team discovered that Chinese yam could replace existing medicine for anti-acid-reflux using an innovative oesophageal experimental model.

In the Physical and Engineering category, Ruth Madden from Ireland won the Gold Prize for her "Microplastic Filter - A Small Solution to a Global Problem ". Ruth and her team designed and built a standalone filtration unit to intercept microplastic particles emanating from a domestic washing machine prior to their entry into the public wastewater system and the wider environment.
