Cotton candy is a fluffy mass of sugary delight and a popular carnival treat that's been exciting children for more than a century. But how does cotton candy get its fine, downy texture?
You might argue we have scientists to thank for our own survival. What breakthroughs have kept the human race from dying out?

Even if you don't operate a scanning electron microscope all that frequently, you might want to brush up on these 10 scientific laws and theories. After all, they're some of our best tools for describing how the universe works.
Seven million (and counting) YouTube viewers can't be wrong. Nano quadrotors are tiny, autonomous flying machines that have the Internet buzzing.

Bend but don't break: That's the idea behind many of these temblor-thwarting technologies. They may even allow a building's inhabitants to walk out unharmed and start picking up the pieces after the earthquake subsides.
Most loss of life in earthquakes comes from people being trapped inside crumbling buildings. And engineers have come up with many techniques to lessen the structural damage. But is there a way to make a building completely earthquake-proof?

Surprisingly, the date stamped on your unopened can of tuna doesn't really have much to do with how safe it is to eat. So what does it mean, and how can you decide whether to eat it or chuck it?
You might have heard of George Washington Carver and Neil deGrasse Tyson. But what about Patricia Bath? Or Percy Julian? Meet 10 African American scientists who have made the world a better place for everyone.
Before the scientific method came along, science dabbled in some pretty far-out ideas in its youth. Remember miasmas? And spontaneous generation? And the four elements?
If you step on a crack, you'll break your mother's back. Surely you know this jingle from childhood. It's a silly example of a correlation with no causation. But there are some real-world instances that we often hear, or maybe even tell?

After the success of craft breweries, it was perhaps inevitable that moonshine would get its own day in the sun. But while you can make both beer and whiskey at home, there are some major differences between them – starting with legality.
Beer is quickly becoming a trendy mixer for more adventurous cocktail drinkers. However, this acidic ingredient doesn't always play well with others. Why can't beer and milk just get along?
The age of a beer can dramatically influence its flavor, and usually not for the better. But what about its alcohol content? Does a decade-old barley pop still pack the same wallop as one bottled the week before?
A quickly poured beer or soda can create a layer of foam -- also known as a "head" -- toward the top of the glass. But while a soda head rapidly disappears, a beer head lingers even after you've begun to drink the beer. How can this be possible?

Few would argue that lab rats lead an easy life. Add to it the assertion that they are prone to cancer just by being lab rats, and we've found a whole new level of depressing. But is it true?
Rats! They're just like family. Evolutionarily, anyway. So when it comes to research and biomedical study, what can they do for us?
The Hybrid Sports Bike, still in its prototype stage, is a three-in-one: a pedal-powered bicycle souped-up with both a gas engine and an electric motor. But how could a gas-powered bike be environmentally friendly?

If you thought that all NASA did was send shuttles into space, prepare to think again. Whether in the doctor's office, hospital or home medicine cabinet, you probably don’t go a day without bumping into some NASA technology.
You might be familiar with space blankets -- those lightweight blankets worn by marathon runners or spectators in a football stadium. The technology was invented by NASA and is just one spinoff in the area of insulation. What are some others?
