It was a chilly winter afternoon when I was visiting a friend’s house. As I absentmindedly left the window ajar, my friend exclaimed, “Close the window! You’re letting the cold in!” We shared a good laugh, but it got me thinking: is cold something that actually “comes in”, or are we, in fact, letting the heat out?

Imagine a vast, shimmering lake, brimming with life. Birds soar above, fish dart below the water’s surface, and children play gleefully along the shore. Fast forward a few decades, and that same spot has become a barren desert, with cracked earth where water once flowed.

When your child first learns about cells, it’s easy to marvel at these tiny building blocks of life. Cells are where the magic of life happens, and recent scientific advancements have put a particular kind of cellular machinery – mRNA – under the limelight. Let’s embark on a journey to understand this exciting domain of science, and how it’s revolutionizing the world of medicine, particularly vaccines.

Unraveling the difference between plant and animal cells isn’t just fascinating; it’s foundational in STEM. By understanding these basic cellular differences, we lay the groundwork for more complex scientific explorations. And it’s through questions like your child’s that we rediscover the wonder of the world around us.
