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.

Climate change is a looming threat to planet Earth, so scientists have been thinking of solutions. One of them is going to Mars in case Earth becomes inhabitable, as scientists think there might be water on Mars. But if someone asked me if I would move to Mars, I would always come out with a straight answer: no.

Can you imagine having a skeleton made of glass? The sea sponge known as Venus’ flower basket can! This glass skeleton has inspired Australian engineers to create a strong new material that could make buildings more sustainable.
