The inside of an igloo isn’t cold—they can get up to 60 degrees! Find out how!

Usually when people picture an igloo, they imagine a dome with a little tunnel attached. This is surprisingly accurate! Igloos are surprisingly hospitable, and it all comes down to science.

Snow makes a surprisingly good insulator. When combined with ice to make the walls of the dome sturdy, it creates a cozy little environment. With the occupant’s body heat and perhaps the use of oil lamps or candles, the walls of the igloo melt a little, but then are soon frozen by the temperatures outside. Several days of this melting and refreezing process creates a nice insulation, sometimes of up to 60 degrees Fahrenheit, which is incredibly welcome when the weather outside is -50 degrees Fahrenheit!

The human eye can spot a candle flame from 30 miles away! Learn more about this amazing organ

The human eye can spot a candle flame from 30 miles away! Learn more about this amazing organ

Think about this next time you complain that you have bad eyesight! The human eye is incredibly sensitive. It’s theoretically possible to see a candle flame from 30 miles away, and the farthest visible light we can see with the naked eye is the Andromeda galaxy, which is 2.6 million light years away!

Of course, there are some limitations. In order to see a candle flame from so far away, it would have to be completely dark and the Earth would have to be flat—or you’d have to look at it from on top of a mountain during a pitch black night!

Dragonflies are the most effective predator in the animal world. How do other predators stack up?

Dragonflies are the most effective predator in the animal world. How do other predators stack up?

The world can be a rough place for some animals. The capture of prey is necessary for survival, obviously, but not all species are in the same league in terms of effectiveness.

The dragonfly stands above the rest in this category. They have earned the distinction of successfully snatching about 95% of their targeted food. As if that weren’t a difficult enough task, the fact that their prey is usually captured in midair adds another reason to be in awe of the dragonfly’s unmatched effectiveness.

For some fresh perspective, compare the lion, for instance. It struggles to catch a quarter of all the prey it pursues. To take another example, look at the great white shark. For all its fearsomeness, it still manages to catch only about half the prey it goes after.

So what is the key to the dragonfly’s success? Scientists have found that they possess a nervous system that allows them to focus sharply on a single object. The neurons that connect the dragonfly’s brain to its flight motor center create a unique ability to follow a moving target, calculate its future position, skillfully change flight paths, and finally, capture a meal.

Then the process starts over again. Dragonflies go beyond having the capacity to capture prey just once. They have an appetite that can seem nearly impossible to satisfy.

Octopi are so intelligent that they’re considered honorary vertebrates in animal cruelty laws!

Octopi are so intelligent that they’re considered honorary vertebrates in animal cruelty laws!

The octopus isn’t the first animal that comes to mind when most people think of intelligent animals. That may make sense given that octopi are classified are invertebrates and belong to the mollusk family. In fact, there are some mollusks that do not have brains at all, such as the clam.

To say that Octopi are intelligent animals requires some definition of what is meant by “intelligence.” Well, they are capable of having emotions, displaying individual personalities, playing with toys, and can even form relationships with people.

These traits are rare among animals, being that only a few species have those abilities to any great extent. Chimpanzees are one example, but that’s hardly unexpected, since they are closely related to humans. In contrast, Octopi are not at all closely related to human beings.

An octopus has a brain about the size of a walnut, which is the largest brain of any invertebrate. It contains an estimated 130 million neurons. Though many are stored in the arms, they are a good indicator of an animal’s intelligence.

Researchers are aware that we cannot know with complete certainty how various animals perceive the world, but we are discovering new things all the time that we never expected.

Locusts are not a separate species of insect. What are they then?

Locusts are not a separate species of insect. What are they then?

If you thought locusts were a species in their own right, you would be far from alone. It is quite a common misconception.

In reality, what we call locusts are really grasshoppers during a certain phase of their life cycles called the swarming phase. The polymorphic grasshopper (a grasshopper that has the ability to change its physical form) may go through a swarming phase. This phase can be brought on by chemicals or overcrowding. It is during that time when they are called locusts.

As locusts, grasshoppers become much stronger, more active, and interact more with each other. Perhaps that is why locusts are associated with huge swarms more so than grasshoppers. As swarms, their superior numbers give them a great advantage when compared with grasshoppers that live as individuals.

It is because of their activity as swarms that locusts have gained such a bad reputation. They have been known to cause millions of dollars in damage to crops. In the 19th century, Rocky Mountain locusts caused trouble across the Western U.S. When 12 trillion locusts devastated nearly 200,000 square miles of agriculture. It was possibly the largest concentration of animals in the history of the world!

If you ever get tired of trading on Wall Street, Somalia has its own pirate stock exchange anyone can participate in!

If you ever get tired of trading on Wall Street, Somalia has its own pirate stock exchange anyone can participate in!

Looking to make it rich in Somalia? Chances are, you’re going to have to get involved with pirates. Luckily, you don’t have to go and risk your neck swashbuckling the modern military forces patrolling the seas. Simply invest in a pirate group and wait for your returns—or you can try to get an honest job, which we recommend.

Pirates need money and supplies to get their scummy, illegal job done. But you can’t walk into a bank and ask for a business loan to get your pirate’s den off the ground—you have to secure capital another way. That’s where the pirate stock exchange comes in, which was established in 2009 in Harardheere. Successful heists can bank up to $10 million against Western commercial vessels, and the pirates are allowing investors to get into the action.

The town of Harardheere has transformed from a small fishing village into a vibrant pirate’s “Wall Street” complete with luxury cars and suits. The district government collects on every dollar which is put toward schools, hospitals and other public needs.

So, if you’re looking for the next hot investment and you don’t care if your business partners are violently stealing stuff, Somalia may be the place for you.

Humans could fly on Saturn’s moon Titan by flapping attached wings.

Humans could fly on Saturn’s moon Titan by flapping attached wings.

Titan, the moon of Saturn, is one of a few candidates for a human colony in the future. The surface gravity on Titan is 0.14g, which is slightly less than the gravity on the Moon. Such low gravity would obviously have long term effects on human health, and would probably be an ongoing issue of high significance. 

Long exposure to low gravity can cause a loss in bone density, muscle density, and a weakened immune system. Similar things have happened to astronauts who have remained in space for long periods of time. Still, the best countermeasure to this is frequent exercise. 

It’s been hypothesized that children born on Titan would adapt to the low gravity atmosphere and therefore would not be able to live a normal life on Earth. The atmospheric pressure on Titan is also one and a half times that of Earth. That means crafts would have a much easier time landing compared to bodies like Mars or the Moon. Titan’s atmosphere, however, contains hydrogen cyanide, which isn’t too good for humans to breathe. In this respect it would require severe terraforming. 

But because of the gravity and atmospheric pressure, the wingspan needed for a craft to fly is much smaller. In fact, it’s so much smaller that a human could, in theory, strap on wings and fly through the air with ease.

The grandson of the designer of Hitler’s bunker built Saddam Hussein’s bunker. Apparently it runs in the family!

The grandson of the designer of Hitler’s bunker built Saddam Hussein’s bunker. Apparently it runs in the family!

Lots of people share their craft with their son or daughter in an attempt to pass on their legacy and the skill that they practice.

However, not many pass on the trade of building bunkers for infamous public enemies. Such appears to be the legacy of the woman who designed Adolf Hitler’s bunker.Two generations later, her grandson would go on to be the designer of Saddam Hussein’s bunker.

One can only guess how a family gets in such a business, but there is no guesswork in regards to why the grandson was asked to build the bunker. Simply put: He was good at his job. Massive bombs created for the purpose of reaching and tearing apart underground bunkers were unable to even scratch the man’s creation.

Layers of concrete in its construction were put in place above the bunker for the purpose of ‘tricking’ any bunker busting bombs that ‘detect’ the amount of levels or floors that it crashes through before it explodes. The palace above the bunker was almost completely mutilated by the explosions, showing just how defensible the designer’s layout turned out to be.
