Dear Readers, As you look forward to your summer holidays, we hope that you will have time to explore ideas that are presented in this issue of Science Focus. After all, we have articles that are related to one of the biggest events this year, the World Cup. Are you intrigued about the design of the football that will be used in this year’s competition? You may want to take it into consideration when you cry about incredible goals scored against your favorite team. Interestingly, the tears you shed are going to be quite different from the ones triggered by pollutants. For those of you who are interested in chemistry, we treat you with a story on chirality beyond the textbook. Do you know what is in common between wine crystals and amino acids? While none of us can live in “seas within the sea” in the SpongeBob cartoon, can you imagine there are living things that can? Finally, we return from deep ocean to the lab and consider how organoids can be used to advance research and medical treatments. We would like to thank those of you who participated in our recent “Science in Transportation” Design Competition. We were very happy to see your creativity and artistry. Please head over to our Instagram page to see the winning entries. Yours faithfully, Prof. Ho Yi Mak Editor-in-Chief 親愛的讀者： 在盼待暑假來臨的同時，希望您能善用假期了解今期《科言》探索 的主題，當中的文章與今年最大盛事世界盃有關。 您對今年比賽用球的設計感興趣嗎？也許您為愛隊失球而痛哭時 應該好好考慮這點，有趣的是那時的眼淚並不會與因污染物觸發的相 同。對於喜愛化學的同學，我們會告訴您一個教科書沒有提及，關於手 性的故事，而您又知道葡萄酒結晶與氨基酸之間的共通之處嗎？此外， 雖然沒有人能在《海綿寶寶》中的「海中之海」存活，但您能想像竟然 有生物可以？最後，我們從深海回到實驗室，探討類器官如何有助推進 科研及疾病治療發展。 我們亦希望感謝最近參加過「交通工具的科學」設計比賽的同學， 大家的創意和藝術才能令我們眼前一亮。請瀏覽我們的 Instagram 專頁查看得獎作品。 主編 麥晧怡教授 敬上 Message from the Editor-in-Chief 主編的話 Copyright © 2026 HKUST E-mail: sciencefocus@ust.hk Homepage: https://sciencefocus.hkust.edu.hk Scientific Advisors 科學顧問 Prof. Jiying Li 黎吉映教授 Prof. Adrian Po 傅凱駿教授 Prof. Kenward Vong 黃敬皓教授 Editor-in-Chief 主編輯 Prof. Ho Yi Mak麥晧怡教授 Managing Editor 總編輯 Daniel Lau 劉劭行 Student Editorial Board學生編委 Editors 編輯 Charlotte Chau 周逸之 Ian Cheng 鄭朗健 Sam Fan 樊潤璋 Roshni Printer Jane Yang 楊靜悠 Daria Zaitseva Social Media Editor 社交媒體編輯 Inushi Dinethsa Galappaththi Graphic Designers 設計師 Nicole Lau 劉芯 Ashley Sia 佘恩萱 Winkie Wong 王穎琪 Contents Science Focus Issue 033, 2026 What’s Happening in Hong Kong? 香港科技活動 "Science in Transportation" Visual Explainer Challenge 1 2026 – Result Announcement 圖解「交通工具的科學」設計比賽 2026 — 結果公佈 Hong Kong Science Museum 35th Anniversary Exhibition 香港科學館 35 周年展覽 Science Today 今日科學 Organoids – An Alternative to Lab Rats? 2 類器官 — 實驗老鼠的替代方案？ Amusing World of Science 趣味科學 The Science of Tears 7 淚之科學 Do “Seas Within the Sea” Like in SpongeBob 12 Really Exist? 《海綿寶寶》中的「海中之海」真的存在嗎？ Decoding the Aerodynamics of Incredible Shots 16 Across the Sport Arena 劃過賽場上空的變幻球：空氣動力學 From Grapes to Diamonds: The Fascinating World 20 of Wine Crystals 從葡萄到鑽石：葡萄酒結晶的奇妙世界
