Butterflies and are some of the sky's most beautiful and colorful creatures, and although they might not seem all that special, they are. People are often surprised by the secrets these tiny insects hold.
During their earlier stages, butterflies and moths are caterpillars. Some caterpillars are poisonous, similar to how their older selves can be. Caterpillars build cocoons around themselves and then turn into butterflies and moths inside. This process is called metamorphosis.
Butterflies and moths do not have mouths to eat. Instead they have tubes. The tube is called a proboscis. These tubes are flexible allowing them to move to the blossom. The butterflies and moths extend their feeding tubes into the blossoms and extract the nectar. This is their food source. To these insects, blossoms are sweet and delicious, even though to humans nectar is bitter. [read more]

Although one might think the Arctic and Antarctic seem basically the same climate wise, they are actually noticeably different. Likewise, they are also affected differently by climate change. Both areas have melting ice, however the two poles have it for a different reason.
The main reason for the difference in climate is the positioning of land around the poles. The North Pole consists of an ocean surrounded by land, while the South Pole is the opposite, a land mass surrounded by ocean. Although this detail may seem meaningless, it actually has a drastic effect on the temperature of the poles.
The Southern Ocean is the only place where there is a ring of ocean, unbroken by land, surrounding the earth. This causes ocean currents to circle Antarctica in what is known as the Circumpolar Current. This current is one of the strongest in the world, and causes massive waves in the Southern Ocean. These waves make countries like South Africa and New Zealand ideal for surfing, but make reaching Antarctica a difficult ordeal. The Circumpolar Current also insulates the continent from warmer air farther north, making it much colder than the Arctic. [read more]

Cleopatra VII ruled as co-regent of Egypt for almost three decades. She was the last in a dynasty of Macedonian rulers founded by Ptolemy, whose family ruled Egypt for 300 years. Cleopatra is best known for being the last pharaoh of Ancient Egypt.
Cleopatra was born in 69 BC to the Pharoah Ptolemy XII and an unknown mother. During her childhood, she was brought up in the palace of Alexandria in Egypt and received a Greek education, as her family was of Greek descent. But she knew quite a few different languages; some of them being, Egyptian, Ethiopian, Hebrew, and Arabic. Cleopatra's family can be traced back to the Macedonian house of the Ptolemies, who took the throne after the death of Alexander the Great.
When she was eighteen years old, Cleopatra's father passed away, leaving his throne to her and her youngest brother, Ptolemy XIII. Right away, Cleopatra and her ten-year-old brother were married and began to co-rule Egypt. Since Cleopatra was much older than her brother, she took control as the main ruler; but once Ptolemy XIII was older, he wanted more power. Soon, he kicked Cleopatra out of the palace and took over as Pharaoh. [read more]

Are genetically modified foods safe to consume?
Over the last two decades, food that consumers have eaten contains genes from other plants that make them either grow faster, taste better or stay fresher for a longer period of time. Foods that have been altered this way are called “genetically modified foods.”
Some reasons companies may modify food is because they want it to look more appealing, or they are trying to give people the vitamins that their bodies need. Each year, for example, around half of a million children go blind, and one or two million children die from the lack of vitamin A. So scientists have developed vitamin A in rice and put it in other foods to help solve this problem. [read more]

Recently, a huge prehistoric Mayan city was uncovered using a revolutionary technology called LiDAR. This discovery may change the way that archeologists look at ancient Mayan civilization. LiDAR is a tool that can help archeologists map out areas and discover previously unnoticed ruins or structures; it helped a team of Mayan civilization experts uncover a huge Mayan city.
The city that they discovered, called the Megalopolis of the Mayan Snake Kings, stretches over an area twice the size of medieval England. It includes over 60,000 stone structures, hidden by the thick Guatemalan jungle, which were previously overlooked. The city was once filled with interconnected palaces, houses, highways, and temples.
This discovery means that archeologists will have to change their viewpoint on ancient Mayan civilization. With such a huge city having existed, the Mayan population must have been much larger than formerly thought: around 10 or 15 million, instead of the five million previously estimated. [read more]
