Wonders of the immune system!
Reading Time: 2 minutesBY PRAVEENA R.G. CHANDRASEGARAN How does the Immune system remember diseases? Did you know that your immune system has a memory? Once it encounters and fights off an infection, it doesn’t forget! If the same disease tries to infect you again, your body can spring into action much faster and more effectively. This memory is […]
SPM school leavers must embrace STEM, TVET courses
Reading Time: 2 minutesI have recently come across a concerning trend that I feel must be addressed. SPM school leavers might have been dissuaded from pursuing STEM (Science, Technology, Engineering, and Mathematics) and TVET (Technical and Vocational Education and Training) courses due to misconceptions about career prospects and income potential. I am sharing my perspective on this issue […]
A ‘sound byte’ on bioacoustics

How much does a cloud weigh?
Reading Time: < 1 minuteResearchers have calculated that an average cumulus cloud is about 500,000 kg. As we know, clouds are made up of water particles and air which both have mass. To determine the weight of a cumulus cloud, researchers need to determine the size and density of the cloud. They have found that the water density of […]
What is Triple Point?
Reading Time: < 1 minuteIn thermodynamics, the triple point of a substance is when the three phases known as solid, liquid, and gas co-exist in equilibrium at a certain point of temperature and pressure. The term “triple point” was given by James Thomson in 1873. There are many substances that have these conditions such as water, hydrogen, carbon dioxide, oxygen, […]
How important are coral reefs?
Reading Time: < 1 minuteCoral reefs, also known as “the rainforests of the sea”, are well known for their beauty and vibrant colours, but apart from that, they are extremely important, both ecologically and economically. Unlike other marine ecosystems, coral reefs support more species per unit area, including about 4,000 species of fish, 800 species of hard corals, and hundreds […]
