Before true cells existed on the earth, organic molecules floated freely in water. The first cell membrane created a compartment so that useful molecules like RNA and proteins could stay close enough to interact with each other, leading to more complex biological functions. However, an important question remains: how did the first protocells on early … Read more

Plastics have revolutionised modern living with their convenience and affordability, but this same ubiquity is spawning an invisible, long-term health crisis. Beyond choking oceans and clogging landfills, plastics are now infiltrating our bodies through microplastic particles and a cocktail of endocrine-disrupting chemicals (EDCs). The evidence is clear and deeply concerning: these substances are interfering with … Read more

If we tried the same thing, the result would be… well, shocking. So what makes birds different? Let’s understand how electricity works. Electricity flows through metal wires, just like water flows through pipes. It moves from a place with high voltage (electric pressure) to a place with low voltage. For electricity to flow, it needs … Read more

Ever imagined seeing a golf ball on the surface of the moon in an image taken from the earth? This is now possible with the Vera C.
