Time for an Easter trick! There are lots of eggs around at this time of year, but this one is sure to raise some eyebrows. And when you’re finished, you can get your parents to help you cook your green egg, so you can gross out your entire family!
Safety: Use clean equipment when handling food. Younger readers should ask an adult to help cook eggs.

Welcome to the four newest members of the periodic table!
The periodic table doesn’t change very often, which is why it’s worth celebrating when it does. This month, three new elements were inaugurated at a ceremony in Russia. And in Tokyo, a fourth was welcomed to the world. Say hello to moscovium, tennessine, oganessson and nihonium!
Let’s back up a bit: what is an element? Elements are the different types of atoms that exist. So oxygen is an element, and hydrogen is an element, but water is not – it’s a chemical made of oxygen and hydrogen atoms. Continue Reading →

Is there life on other planets? It may seem like we’re alone in the universe, but there’s still hope. The race is on to find signs of life on Earth-like planets, which have atmospheres and liquid water on the surface.
Recently, it was announced that scientists have discovered seven planets orbiting nearby star TRAPPIST-1, each with the possibility of liquid water. Continue Reading →
The numbers that we use are not the only way to write numbers. You might know how to count with tally marks, or read Roman numerals. But there are plenty of other ways to write numbers. This one comes from the Maya people.
CSIRO scientist Amalia Berna and her team are developing a new way to diagnose malaria.
It’s really annoying to get bitten by a mosquito. Your skin often swells, and the bite can itch for days. But in many places in the world, that small bite isn’t just annoying. It can cause a life-threatening disease: malaria.
Malaria is a very tricky disease. Once you are infected, it can take weeks before you start to feel sick. Even then, malaria feels just like the ‘flu. Blood tests are expensive, and it can take several days to get the results, so most people don’t get tested. They just stay home and wait to get better. Sadly, not everyone recovers – malaria kills almost half a million people worldwide each year. Continue Reading →
Can tomato breeders make tomatoes tasty again? Image: Penny Greb, USDA ARS
They’re bright red, a bit crunchy, and they don’t really taste like much. The standard tomatoes you can buy in a supermarket are a bit boring to eat. But if you’ve ever grown tomatoes yourself, you’ll know how sweet and full of flavour they can be. So what’s happened to the humble tomato?
It’s not just your imagination. For years, supermarket tomatoes have been getting less and less delicious. But now, an international team of scientists is on the case, trying to bring back tasty tomatoes. Continue Reading →
