Are Glow-in-the-Dark watches a radiation hazard? Should you store your best timepiece in a lead lined box? Find the answer in this Question of the Week. Plus, we ask how smells travel underwater, and how a shark can smell a drop of blood in an entire ocean...
Does our memory have a limited capacity? In this Question of the Week, we'll find out if learning something new pushes out old information and why your brain needs a regular workout. We'll also ask whether glow in the dark watches give off dangerous radiation and should be kept in lead-lined boxes!
Do we drink the same water that dinosaurs drank? Has your water passed through the countless bladders of the past? In this Question of the Week, we find out if our drinking water has been repeatedly recycled. We also ask if the human brain has a limited capacity, and if so, do we forget the old to make space for the new?
How old is the oldest organism? In this Question of the Week we find out if any organism has found the secret of eternal life, and can truly live forever. Plus, we ask if all the water on Earth has been drunk before, and how much data can our brain take before it's full?
How does the Bornean Flat-Headed Frog breathe when it has no lungs? No, it's not a bad joke, it's our Question of the Week! We find out how this marvellous little frog survives, and ask if any animals live forever, and if the water we drink today was once drunk by dinosaurs?
Why are dreams so hard to remember? In this Question of the Week, we find out why your night time imagination slips away as you wake and is gone before your first coffee! Plus, we ask how certain frogs can breathe without lungs, and can anything truly live forever?
Why are copper compounds so colourful? In this week's Question of the Week we find out how one metal can have so many colourful compounds, as well as a distinctive green flame. Plus, we ask why dreams are so hard to remember, even the really good ones, and how can a frog can breathe through its skin, with no help from lungs or gills?
Being struck by lightning can be a heart-stopping experience - but could a second strike re-start your heart? In this question of the week, we find out if a bolt could act as a defibrillator, and if your body could take it! Plus, we ask why copper comes in different colours, and why we can't remember our dreams.
If you burn your Pizza to a crisp, are you're left with a low calorie (if not very tasty) meal? In this Question of the Week we find out whether cooking contributes calories to a dish, or turn your lunch into the slimmers option. Plus, we ask if a second bolt of lightning would act as a defibrillator and re-start your heart after A first strike had stopped it, and ask why copper comes in countless colours?
Most fish live in either freshwater or saltwater, but some live in both. In this Question of the Week we find out how these fish manage to avoid becoming too salty or too watery. Also, we ask if you burn your food, do the calories go up in smoke, and if a second lightning strike can act as a defibrillator, re-starting your heart after the first bolt stopped it?!
How do you make a didgeridoo do what it does do? For this week's QotW, we find out how the length and shape of the instrument and the skill of the player affects the sound of a didgeridoo. Plus, we ask how fish can cope with both fresh and salt water, and if burning your pizza can turn it into a low-calorie equivalent of its former self!
If we ever do find alien life around other stars, just how would E.T. phone home? We find out what technology we would need to communicate with our nearest stars, and the practical limitations. Plus, we seek the secrets of the didgeridoo, and ask if salt water fish have more permeable skin.
How long was a big dino's lifespan? On this week's Question of the Week, we find out how many candles a dinosaur birthday cake would have, and how we can tell from only fossilised remains. Also, we ask, what technology will we need to communicate with nearby stars (assuming we find anything to communicate with) and how does the shape of a didgeridoo affect it's sound?
Wearing earplugs may help to cut out external noises, but why does it make it impossible to eat crunchy crisps? In this Question of the Week, we find out why earbud headphones make internal noises so loud, and ask how long did a dinosaur live, and what technology will we need to communicate with life around other stars?
What keeps the Olympic torch alight, in flight? To keep the Olympic spirit burning, it must need to travel on aeroplanes, but how do you keep a naked flame burning, while keeping other passengers safe? We find out from one of the designers of the Sydney Olympic Torch. Plus, we ask why earplugs seem to amplify your internal noises, and they may have all died out, just how long did a dinosaur live?
