40 Chinese University Bulletin No.2, 2019 R esearch State-of-the-art Screening for Babies-to-be The Department of Obstetrics and Gynaecology introduced fetal DNA sequencing at genome-wide resolution for prenatal invasive genetic diagnosis. The technique optimizes detections of microdeletions and microduplications in fetus to offer augmented accuracy in diagnosing lethal congenital disorders, such as Down syndrome. Goodbye to Malicious Click Interception A research team led by Prof. Meng Wei of the Department of Computer Science and Engineering developed a browser-based analysis framework Observer capable of detecting three different techniques for intercepting web user clicks. These include the modification of hyperlinks, the insertion of event listeners, and visual deception. The framework’s source code will be released to the public to help browser vendors design defense mechanisms and put in place a more salutary web ecosystem. Diamond Quantum Sensor Research groups led by Prof. Goh Swee-kuan and Prof. Yang Sen of the Department of Physics have developed an observation technique for quantum materials based on nano-diamonds. Under low temperatures and high pressure, quantum materials display such interesting characteristics as becoming a superconductor. Unfortunately, it was difficult to observe these characteristics given the extreme environment. Using nano-diamonds, the research team has developed a method of sensing magnetic fields of quantum superconductors that works under extreme conditions. This method makes it easier for researchers to study and improve quantum materials, while enhancing Hong Kong’s capability in the fields of metrology and high- precision instrumentation.
