The eyes on the wings of a butterfly can look kind of strange, but they're not looking at you, they're just a deflecting mechanism. Like a lot of butterfly species, the African satyrid butterfly's eyespots make predators more likely to attack its wings rather than the more vital parts of its body.

Scientists have noticed that global precipitation tends to drop after a volcanic eruption, but they haven't known all the factors that can influence this effect. Now, thanks to a new study, a group of researchers thinks the missing link is El Niño, the weather pattern we normally see every 2 to 7 years.

You're in a line at a cafeteria. You take a plate off the top of a stack of plates. The other plates in the stack rise from below just far enough to present the next plate at the same height as the one you just took. This system reflects a general principle of springs: if you put twice as much force on a spring, it compresses, or stretches, twice as far.

In order to fight climate change, we need to find new ways of generating electricity that don't involve burning fuels and generating greenhouse gases. Physicists know that there is energy available in the temperature difference between a hot object and its cooler surroundings. A thermoelectrice device is made of special materials that can capture this energy and convert it directly into electricity, without any moving parts.

People who listen to music a lot can perceive the similarity between two of the same notes in different octaves. This may not seem like such a unique ability, since most people in Western countries are able to do this. Still, scientists have long wondered whether it's innate knowledge or learned through exposure.

While the first human civilizations grew in Mesopotamia, and the ancient Egyptians were building the pyraminds, there were still woolly mammoths living on a remote arctic island.
The Apollo 11 mission that landed the first humans on the moon famously blasted off from Florida, but NASA was in Arizona, too. In 1967, two years before Neil Armstrong left his footprint in the lunar dust, engineers figured out a way to recreate the moon's surface . . . on Earth.
Voices often indicate thoughts and emotions indirectly. Cues in the form of pitches, tones and pauses are qualities of voices that listeners use to make inferences about a speaker's mind. But those cues aren't always represented in content that we read, like in a transcript or a text message.
Last time on A Moment Of Science we learned about plants that disperse their seeds via zoochory, meaning they've evolved various ways to hitch rides with animals. A particularly interesting case of this latter form of zoochory is mistletoe, the holiday smooching plant.
Just as animals are often driven to great lengths, literally and figuratively, to propagate their species, plants too are driven to reproduce. To do this, plants need to disperse their seeds, so that they have space to germinate and grow.
Seeds aren't as dangerous as some urban legends might lead you to believe, but they also aren't very good for you, either.
When making plans for the weekend, some people like to be by themselves, while others prefer to be go out and be social. To learn more about these two types of people, sometimes called introverts and extroverts, researchers tried to see what would happen if one type tried to act like the other.

In the midst of winter, one of the best ways to combat the effects of cold weather is a hot beverage. A new study out of the University of London shows that we're not the only species that likes a hot drink. In fact, bumblebees prefer warm nectar to cool.
Things are not always as they seem, and this little demonstration will prove it. All you need is a cup of black coffee and an overhead light.
The Northern Lights, also known as the Aurora Borealis, are waving ribbons of green, red and purple in the sky. These curtains of light can be seen as far south as the South Pole. In the southern hemisphere, however, they're called the Aurora Australis. They can also sometimes be seen in New Zealand or Chile.
