Researchers from Rice University discovered that iron corrodes even in presence of supercritical CO2 with trace amount of water. Iron corrodes even in this ‘essentially inert’ fluid due to two reasons. Read more to find out what those reasons are! Credit: Evgeni Penev/Rice University

One of the major issues with quantum computing has been the ability to control and use a 3 qubit system efficiently. Other than silicon, two other main approaches to creating such a system have been used; superconductors and ions. This problem is important to solve as 3 is the lowest number of bits/qubits which allows for logic operations and error correction. Scientists from three universities, not one but three, have made it possible for a quantum computer to be 99% accurate by just using silicon which we already use in our daily devices. This is a huge milestone as it speeds up the reality of quantum computing. Read more in the article to find out how they did it! Credit: Tony Melov / UNSW

Summary: Indium is one of the rarest metals in the world and is running out due to its usage in mobile screens and computer screens in the form of Indium Tin Oxide (ITO). As expected, scientists have forever been trying to find a replacement as good as this in terms of electronic or optical properties. Researchers from Paragraf and Queen Mary University of London have recently published a paper proving that Graphene could be used instead for these OLED screens as well creating a much cheaper alternative for use. “Our paper is the first paper in the world to demonstrate that graphene can replace ITO in an electronic/optical device. We have shown that a graphene-OLED has identical performance to an ITO-OLED. ITO-OLEDs are widely used as the touch screens on our mobile phones", says Professor Colin Humphreys of Queen Mary and Paragraf. Credit: Unsplash/CC0 Public Domain

Wow…that was a great movie and so long ago too. But in reality, no terminator, although robots are being used in places like Japan in restaurants and hotels. However, soft materials and soft robots are what is being currently researched in many places including NUS MSE. As the title suggests, researchers from Southeast University, China have created a material that behaves like a starfish: changes its color, shape to camouflage and even self heals its tentacles.
