The global race for fifth generation supremacy is under way, with countries competing to be the first to provide 5G mobile broadband services. The ultra-fast network will prompt inventions, of which today we cannot even dream. Countries around the world have devoted much resources to developing, manufacturing and deploying the new equipment necessary for 5G transmissions. China, for instance, has recently become highly influential in the field with its ability to develop infrastructure for 5G systems worldwide. In Asia, Hong Kong has been blamed for being slow to launch the new service in comparison with the mainland, South Korea and Japan. Actually, a delay is not necessarily a bad thing, as it allows Hong Kong to have a longer testing period to ensure a more reliable and decent 5G mobile service. Hong Kong's privately-owned telecom market is very competitive and cautious.

香港科技大学（科大）水底机械人大赛小队於2019年MATE国际水底机械人大赛勇夺全场总冠军及工程演说冠军。这是队伍继2017年后，再次於是次比赛中获得全场总冠军，亦是目前唯一一支在比赛举办18年来获得这个最高荣誉的亚洲队伍。

Humans are creatures who often judge whether a dish is attractive or a stranger is friendly simply by their own eyes. But our sense of smell is just as important. We all may have the experience of eating with a stuffy nose and found a dish to be tasteless or using our nose to check whether it has gone bad. Moreover, people tend to keep their distance from a person with an unpleasant odor, while special odors like gas can alert us to dangers of a leak. As the old Chinese adage goes, "My shack is better than an emperor's bed." What makes our own shack better? Our smell, together with the smell of our family members, and pets as well if any, makes it unique and reassuring. To understand how smell impacts people, researchers at the University of British Columbia, Canada, invited 96 couples for a study last year.

Our fishery gave birth to a love of seafood, but it is also contributing to the global fish stocks decline. We degraded it through overfishing, pollution and reclamation before building a fleet to ravage fisheries in other places. Many cities have actually done the same. Ironically, calls to save global fish stocks come from cities that sacrificed their own fisheries. Yet, Hong Kong also shows the way to a solution. It retains a resilient population of people who fish, those with the expertise and toughness to build a sustainable fishery, that is, such as those where catch volume and fishing practices allow for continual regeneration of stock, while enabling fishers to achieve a decent standard of living. People in the industry will overfish and abuse the ecosystem to provide more income if they can't afford a living. But our highly adaptable fishermen can demonstrate a global model for sustainable fishery.

香港科技大学机械人竞赛团队—水底机械人小队在第14届MATE国际水底机械人大赛香港区赛成功卫冕，蝉联九届冠军。该支队伍将代表香港，参加在6月20至22日於美国田纳西州金斯波特水上运动中心举行的国际赛。

香港科技大学环境研究所今日推出崭新的流动应用程序 PRAISE-HK，旨在减少空气污染对用户的个人健康威胁。PRAISE-HK 全名是「个人化实时空气污染风险信息系统 」(英文：Personalized Real-time Air-quality Informatics System for Exposure – Hong Kong)，将有助香港成为世界级的智慧健康城市。PRAISE-HK 是汇丰150周年慈善计划自2016年11月起资助，为期五年的项目，流动应用程序和系统分三个阶段推进：(1)    第一阶段 - 今日发表的应用程序以高分辨率（达2米至20米）的街道级别地图提供室外空气质素信息；(2)    第二阶段 - 全面整合空气污染对个人健康威胁的信息，追踪个人由室内至室外（包括于交通工具内）所接触空气污染水平；(3)    第三阶段 - 完成互动应用程序及系统，根据个人对空气污染的反应提供健康预测警报。 什么是PRAISE-HK？PRAISE-HK是一款智能城市应用程序，提供最先进的街道级别实时空气质素和健康风险信息和48小时空气质素预报。PRAISE-HK 显示「空气质素健康指数」（AQHI）以及由四种空气污染物：二氧化氮（NO2）、臭氧（O3）、悬浮粒子（PM10 和PM2.5)）和二氧化硫（SO2） 所导致入院的个别健康风险增幅总和 (%AR)。用户可在 PRAISE-HK 应用程序获取上述的实用信息，然后采取相应措施，减少短期曝露于空气污染物的风险，对空气污染物敏感的人士会大大受益于此程序。PRAISE-HK应用程序是由香港科技大学环境研究所开发的全新系统，项目由跨学科专家领导，其高精准度可归功于以下重要技术： 

Unmanned aircraft systems started to gain attention in US military operations more than a decade ago, but nowadays, people enjoy flying drones for photography and videography purposes. Drones are also gaining widespread acceptance for goods delivery, surveying and scientific research. I have two recreational drones, so I was eager to examine the three-month drone regulation proposals put out by the Civil Aviation Department in late 2017. There are six recommendations for the UAS regulatory regime: a registration system; risk-based classification of operations; training and assessment requirements; drone maps; insurance requirements; and indoor operations. The recommendations are sound, but a number of salient issues were omitted. The first is the absence of regulations governing drone manufacturers.

非文科本科生经常抱怨被迫修读跟他们的主修范畴以及职业生涯毫无关系的人文学科。然而，人文学部副教授渡言并不认同这个想法。渡教授认为，科学家以及工程师也应该修读文科及人文学科，才能了解他们的发明能为社会和人类带来什么样的影响。渡教授希望更多学生能够透过她的课堂培养同理心、批判性和创意思维。 「人文学科是一种软实力。它对人类的影响有时甚至比科学发明更深远。」她以历史上的著名作家莎士比亚以及鲁迅为例子，后者为中国的文坛大师，因为坚信文字的力量远大于医学，故决定弃医从文。 现今的学生都喜欢追求视觉上的刺激，因此他们都无图像不欢。正如渡教授所言，电影和动画这个媒介比文学让人感觉更自由，亦比书本更受欢迎和更容易接近。 因此她认为，「电影和动画是灌输学生人道主义价值观一个很好的媒介。」 渡教授是研究中国动画的著名学者，她最先发现中国动画电影在二战时期的重要性，并且将其建立为一个主流研究范畴。渡教授醉心研究动画，源于她在美国攻读博士学位时发现动画可以成为一门独立的研究议题。但同时她亦对其友侪只谈论日本动画的行径感到好奇，促使她决定深入研究中国动画这一个前人未曾涉猎的研究领域。 渡教授于2012年完成她的博士论文，发表中国动画对日本动画的影响，以及中国动画在50至70年代毛泽东领导下蜚声国际。今年，渡教授出版了她的英文著作《Animated Encounters: Transnational Movements of Chinese Animation, 1940s-1970s》。 渡教授还认为，因为人们对科技的看法不断改变，所以现今不论修读什么科目的学生都应该修读人文学科。日本动画对科技的描述就是最佳例证—在60年代，科技在动画里头都是好帮手，造福人类。然而，近代动画却经常刻划疯狂科学家创造能够摧毁人类文明的怪兽机器，展现出对科技的恐惧。 她表示：「科学发展存在失控的可能性。虽然机械人能为人类带来便利，但同时也可能带来破坏。我希望学生以人道关怀和价值为做事原则，这样才可确保科学和技术用于正途。」
