In April, Double Helix reader, Owen Bardell, got the chance to write a review for a new book called Caution! This Book Contains Deadly Reptiles by Corey Tutt and illustrated by Ben Williams.

Catching prey can be a real chore when you’re a parasitic insect desperate to catch a meal for your babies. Sometimes it’d be easier to let your bum do all the work for you.

The chocolate season is here! Why not try a bit of clever chemistry to enjoy a bit of ice cream before the weather chills too much? In this delicious experiment, we combine different ingredients to change the melting point of chocolate.

From tiny viruses to the oldest of stars, everything science-y is on-topic in this quiz. Can you get a 5 out of 5? We think you’re all over it!

Focussing on a patch of sky covering roughly the same area as 100 full moons, the Square Kilometre Array (SKA) radio telescope in Western Australia has captured the bright glow of dozens of galaxies as they looked billions of years in the past.

We clap to get people’s attention, to say “congratulations” and even to make music. But have you noticed that everyone’s claps sound a little different? A team of physicists have now figured out why, and they think we might one day be able to tell who someone is just from their claps.

In this activity we are going to take a look at how some dinosaurs may have digested their food.

Australia’s Renewable Energy Agency (ARENA) recently launched its $100 million Solar ScaleUp Challenge and this could spell good news for climate change action. The challenge aims to connect solar technology engineers from across the country and make progress towards lowering carbon emissions.

A ground-breaking new study has linked high concentrations of PFAS – also known as ‘forever chemicals’ – with health impacts and population decline in freshwater turtles. The study was led by scientists from CSIRO, Australia’s national science agency, and the Queensland Department of the Environment, Tourism, Science and Innovation (DETSI).

Whether it’s stress and uncertainty from forced displacements from wildfires, rises in sea level, or fear and hunger from poor nutrition in places where people can’t grow food, climate change is one of Earth’s biggest threats. Indeed, recent scientific discoveries show that mosquito-induced dengue cases are set to double in the next 25 years, especially in warmer areas like the Americas and Asia, and could potentially affect over 250 million people.
