Dr Anissa Widjaja, our SBS alumni and currently a senior research fellow at the Duke-NUS’ Cardiovascular and Metabolic Disorders Programme, was recently featured in The Straits Times. Read more
The Role of Gravity in Connecting Microscopic and Macroscopic World
The laws of physics, as we understand them, can be divided into two realms: classical physics, which describes objects at human size scales or larger, and quantum physics, which describes objects at the atomic scale. These two sets of laws are very different. Classical physics states that an object like a ball has a position and momentum that can both be determined to arbitrary precision. Read more
The Chemical Midas Touch – Combining Gold with Natural Products to Create Novel Antimalarial Drugs
Malaria is one of the worst scourges ever known to mankind. The deadly disease, which is caused by plasmodium parasites transmitted by the female anopheles mosquito, remains a global public health threat despite concerted efforts to eradicate it. In 2016 alone, it infected 194 million people in Africa and caused 445,000 deaths. Read more
SHA-1 collision attacks are now actually practical and a looming danger
Hash functions play important roles in information security, serving as the basic building blocks for many security protocols. They must possess one vital feature: it has to be mathematically hard for an attacker to find two inputs that map to the same output (called a “collision”). Read more
More childhood nature experiences could make Singaporeans more tolerant towards local wildlife
“I could climb trees like a young chimp and if challenged, could even swing upside down from branches.” The quote is from the book Kampong Spirit Gotong Royong. Life in Potong Pasir, 1955 – 1965 by Josephine Chia, (pp. 62), depicting life in a Singapore kampong during the years leading up to independence. Read more
The evolution of skyrmions in Ir/Fe/Co/Pt multilayers and their topological Hall signature
Magnetic skyrmions are tiny entities, manifesting in magnetic materials, that consist of localized twists in the magnetization direction of the medium. Each skyrmion is highly stable because eliminating it requires untwisting the magnetization direction of the material, just as a knot on a string can only be untied by pulling the rest of the string out of the knot.
