Dear Readers, For your Easter holiday, we present to you a new issue of Science Focus. For those of you who are interested in evolution, we have two articles that may expand your views. In one, we consider the unexpected outcomes of evolution in cavefish, as they adapt to a habitat without sunlight. The second article describes the transfer of genetic material between different species, beyond the usual example of how antibiotics resistance spread among bacteria. For mathematics enthusiasts, we consider why a coastline cannot be measured accurately. Finally, three generations of chemists share their stories about studying as undergraduates in HKUST. The School of Science has organized a variety of on-campus STEAM activities in the coming weeks, including workshops and information sessions. I hope that some of you will have the opportunity to visit us at these events. Yours faithfully, Prof. Ho Yi Mak Editor-in-Chief 親愛的讀者： 為著這個復活節假期，我們向大家呈獻最新一期《科言》。 對進化有興趣的讀者，我們準備了兩篇或許可以使您拓闊視野的 文章。其中一篇探討洞穴魚在適應黑暗環境時意外演化出的不尋常特 徵；第二篇討論除了抗生素抗性在細菌間傳遞的典型例子外，遺傳物 質如何在物種間傳遞。此外，數學愛好者可以閱讀為何海岸線不能被 準確地量度一文。最後，三個於不同年代在科大就讀的化學家將向大 家分享他們就讀本科時的經歷。 理學院將於未來數週在科大校園舉辦不同的 STEAM活動，包括 工作坊和簡介會等。希望屆時有機會與大家碰面！ 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. Ivan Ip 葉智皓教授 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 Sam Fan 樊潤璋 Roshni Printer Devandhira Wijaya Wangsa Helen Wong 王思齊 Jane Yang 楊靜悠 Daria Zaitseva Social Media Editors 社交媒體編輯 Audrey Chan 陳皚慧 Daisy Yeung 楊于葶 Graphic Designers 設計師 Jacky Lau 劉重信 Yerim Song 宋禮林 Winkie Wong 王穎琪 Contents Science Focus Issue 032, 2026 What’s Happening in Hong Kong? 香港科技活動 Building a Dream Palace 1 築夢天宮 Desert Elephants: The Adventures of Little Foot 沙漠小象走天涯 Amusing World of Science 趣味科學 Survival of the Sightless: Why Did Cavefish Go Blind? 2 瞎者生存：洞穴魚為何失去視力？ Dimension Between Integers: Can We Measure the 6 Length of a Coastline? 整數之間的維度：我們能測量海岸線的長度嗎？ Does Life Evolve Like a Great Branching Tree? 12 演化樹真的是樹狀嗎？ Who’s Who 科言人語 Q&A with HKUST Chemistry Majors 17 讀化學的人：與科大學子對談
