Maybe you’ve heard about quantum in science class or maybe in a sci-fi book! No matter where you’ve come across it, you probably know it’s a bit strange, maybe confusing but also possibly an important part of the future. And all these things are true!

Nathan K. Long is a Participant in the 2024 Quantum Explained Challenge put on by the Australian Institute of Physics, Cosmos and Double Helix Extra. This entry impressed our panel of expert judges for making a quantum concept clear to a middle school audience in less than 250 words.

2024 is winding to a close and 2025 is just around the corner. What better way to celebrate than with a science quiz! This quiz contains (almost) all of the science trivia questions featured in Double Helix Extra throughout 2024. There’s over 100 science questions to discover!

Our Microscope column answers the most intriguing science, tech, engineering and maths queries you can throw at us. So, why do voices sound so different on voice recordings?

When astronomers first looked at the Moon through telescopes, they thought they were seeing great oceans. They gave the Moon’s big, dark patches names such as Oceanus Procellarum, and the Sea of Tranquillity. Now we know that these ‘seas’ are ancient lava flows, and that the Moon’s surface is very dry.

Have you ever wondered how water striders can walk on water? Wonder no longer!

Twinkle, twinkle, giant stars! Pairs of so-called ‘heartbeat’ stars change their brightness like the rhythm of a beating heart. For the first time, new models show that they also create gigantic waves.

From unstoppable scientists to terrifying natural phenomena, we’re taking on forces of nature. Naturally we hope you get a 5/5, but don’t force it!
