Cockroaches make group decisions. When 50 cockroaches are presented with 3 shelters that can only house 40, they'll split up "perfectly"


Humans aren’t the only organisms that communicate to each other. In fact, a lot of them do.

One of these organisms is the cockroach who use chemical and tactile communication to organize themselves.

"[Cockroaches] can also use vision [to communicate]," says Dr José Halloy, a scientist in the Department of Social Ecology at the Free University of Brussels in Belgium. "When they encounter each other they recognize if they belong to the same colony thanks to their antennae that are 'nooses', that is, sophisticated olfactory organs that are very sensitive," he says.

This communication is fairly intelligent as well. When testing how they communicate, it was found that cockroaches will divide themselves up perfectly after much “consultation”.

For example, if 50 insects were placed in a dish with three shelters, each with a capacity for 40 bugs, 25 roaches huddled together in the first shelter, 25 gathered in the second shelter, and the third was left vacant.When the researchers altered this set-up so that it had three shelters with a capacity for more than 50 insects, all the cockroaches moved into the first "house".

There is a tiny island with 825 unique species on it! Where is it?


Socotra is a small cluster of four island in the Indian Ocean, off the coast of Yemen. In this cluster of islands, the largest island is also called Socotra, and this island contains 825 species of plants that don’t exist anywhere else in the world! The explanation as to how this happened is actually very simple. Around 250 million years ago, whenever all major landmasses were joined, most life forms were able to roam freely from one region to another!

However, Socotra was already an island by itself at that point. This isolation from the other land masses meant that for the existing life forms on Scootra, the evolutionary process that would happen to these species wouldn’t spread anywhere else!

Next time you want to repel mosquitoes, drink Green Tea. This is why that helps.


Mosquitoes are so pesky. We spend so much on citronella candles and sprays to keep the things away from us.

To keep them out of your house, make sure all sugary items are sealed well. Open cans of pop and fruit lying around are havens for mosquitoes and other pests like gnats.

Bounce dryer sheets repel a number of pests from mosquitoes to wasps and even mice. Place them around the house and by windows and the chemicals in the dryer sheets repel them.

Well brewed and unsweetened green tea repels mosquitoes from your skin. Drinking green tea instead of pop or juice is a much better option.

The chemicals in the green tea are excreted through your pores. It acts as a natural mosquito repellent.

The less sugar in your system, the better, because mosquitoes are attracted to sugar. So, there you have it. Cut out the sugar and drink green tea. It's healthier, anyways.

Some awesome lists!

Real scientists published a paper called 'The Effects of Peanut Butter on the Rotation of the Earth.' Want to know the result?


While one or two people work on things like perfecting male birth control or creating date rape combatting tools, it took hundreds of people to author a study on just how peanut butter affects Earth’s rotation. Even sillier than this notion? The list of co-authors is longer than the result of the study. 

There are literally hundreds of authors on the study all working together to come up with a result. And what is that result? “So far as we can determine, peanut butter has no effect on the rotation of the earth.” That’s the entire result of the study that took more than 250 people to come up with and research. Perhaps George Washington Carver would be proud. Who said scientists don't have a sense of humor?

There's a Lightning storm in Venezuela that's been going on since at least the 16th century!


Relámpago del Catatumbo (Catatumbo Lightning) is an atmospheric phenomenon that occurs where the Catatumbo River meets the Lake Maracaibo, in Venezuela.

How do they happen? The winds blowing accross the Maracaibo lake and other swampy plains around the area meet with the Andes mountain ridges. These winds carry a lot of heat and moisture, which are perfect for creating electric charges. The result? Lightning for 280 times an hour, 10 hours a day for 160 nights a year!

It is believed that the phenomenon has been going around since at least the 16th century (and most likely, even more than that). The first time this storm was reported in writing was an epic poem called "la Dragontea," by Lope de Vega in 1597, which told of the defeat of Sir Francis Drake at this site. Drake tried to attack the city of Maracaibo, but the lightning gave away his position and the city was able to respond in time.

All the electric activity makes the Catatumbo Lightning the largest single generator of Ozone in the planet. The lightning is visible up to 400 km away! Because of this, it's also called as the Maracaibo Beacon.
