How do noise cancelling headphones work?
Just by covering your ears, headphones help block the sounds around you. But active noise cancellation takes a little bit more work. Different sounds have different waveforms. And a microphone on noise cancelling headphones registers the waveforms coming from the sounds aro...

Why are lakes freshwater and oceans saltwater?
It has something to do with this leaky faucet. You see, rain falls on the land as fresh water. As this water flows downward, it ever so slightly erodes the rocks and soil. This causes an ever so slight amount of salt and minerals to dissolve in the water and continue downstream. Ev...

Is fire a solid, a liquid or a gas?
The answer is none of the above. Contrary to what the ancient Greeks thought, not only is fire not one of four basic elements that make up everything in the universe, fire isn’t even a substance. It’s a process. As any good Boy Scout knows, to light a fire, you need thre...

What happens to you in space without a space suit?
Bad things happen, my friends. Lots of bad things. Our bodies depend on Earth's atmosphere to survive. Not just for oxygen. The atmosphere protects us from ultraviolet radiation. It regulates temperatures. And it wraps us in a cocoon of lovely, lovely air pressure. In the v...

New frogs found. And they “dance.”
Fourteen new species of dancing frogs have been found in the jungle mountains of southern India. The tiny amphibians earned their name with the unusual kicks they use to attract mates. One problem, though. The species declined in number during the 12 years in which Indian sc...

Can you make a man out of a monkey?
Humans share ninety eight percent of their DNA with chimpanzees, so could you genetically engineer the rest to make it into a human? Settle down, we’re not making any human-animal hybrids around here. Even if we wanted to, it doesn’t mean we can. See, the important thin...

Does the 5-second rule really work?
The 5-second rule states that food dropped on the floor for less than 5 seconds is still safe to eat. But to really answer the question, we need to ask another – how lucky do you feel? It can take less than 5 seconds for 150 to 8,000 bacteria like Salmonella to hop a ride...

Which animal lives longest?
Sticking with recorded history, the answer might surprise you. It’s not elephants, which live for about 30 or 40 years. It’s not giant tortoises either, even though they often ripen to be well over 100 years old. It’s not even that record-breaking, 507-year-old Arctic clam na...
