Margay (Leopardus wiedii)

The Margay is a solitary and nocturnal animal that prefers remote sections of the rainforest. Although it was once believed to be vulnerable to extinction, the IUCN now lists it as “Near Threatened”. The margay is found from southern Mexico, through Central America and in northern South America east of the Andes. The southern edge of its range reaches Uruguay and northern Argentina. They are found almost exclusively in areas of dense forest, ranging from tropical evergreen forest to tropical dry forest and high cloud forest. They are hunted mainly for their fur and this has resulted in a large population decrease - around 14,000 are killed a year. They also suffer from a loss of habitat, which is also a significant part of this decline.Of all of the felines, the Margay is most adapted for a true arboreal life. It is the only cat to possess the ability to rotate its hind legs 180° , enabling it to run head first down trees like squirrels. It can also hang from a branch by one hind foot! This cat eats small mammals (sometimes including monkeys), birds, eggs, lizards and tree frogs. It may also eat grass and other vegetation, most likely to help digestion.

MATH MYTHS: (from Mind over Math)
1. MEN ARE BETTER IN MATH THAN WOMEN. Research has failed to show any difference between men and women in mathematical ability. Men are reluctant to admit they have problems so they express difficulty with math by saying, “I could do it if I tried.” Women are often too ready to admit inadequacy and say, “I just can’t do math.”
2. MATH REQUIRES LOGIC, NOT INTUITION.  Few people are aware that intuition is the cornerstone of doing math and solving problems. Mathematicians always think intuitively first. Everyone has mathematical intuition; they just have not learned to use or trust it. It is amazing how often the first idea you come up with turns out to be correct.
3. MATH IS NOT CREATIVE.  Creativity is as central to mathematics as it is to art, literature, and music. The act of creation involves diametrical opposites—working intensely and relaxing, the frustration of failure and elation of discovery, satisfaction of seeing all the pieces fit together. It requires imagination, intellect, intuition, and aesthetic about the rightness of things.
4. YOU MUST ALWAYS KNOW HOW YOU GOT THE ANSWER. Getting the answer to a problem and knowing how the answer was derived are independent processes. If you are consistently right, then you know how to do the problem. There is no need to explain it.
5. THERE IS A BEST WAY TO DO MATH PROBLEMS.  A math problem may be solved by a variety of methods which express individuality and originality-but there is no best way. New and interesting techniques for doing all levels of mathematics, from arithmetic to calculus, have been discovered by students. The way math is done is very individual and personal and the best method is the one which you feel most comfortable.
6. IT’S ALWAYS IMPORTANT TO GET THE ANSWER EXACTLY RIGHT. The ability to obtain approximate answer is often more important than getting exact answers. Feeling about the importance of the answer often are a reversion to early school years when arithmetic was taught as a feeling that you were “good” when you got the right answer and “bad” when you did not.
7. IT’S BAD TO COUNT ON YOUR FINGERS. There is nothing wrong with counting on fingers as an aid to doing arithmetic. Counting on fingers actually indicates an understanding of arithmetic-more understanding than if everything were memorized.
8. MATHEMATICIANS DO PROBLEMS QUICKLY, IN THEIR HEADS. Solving new problems or learning new material is always difficult and time consuming. The only problems mathematicians do quickly are those they have solved before. Speed is not a measure of ability. It is the result of experience and practice.
9. MATH REQUIRES A GOOD MEMORY. Knowing math means that concepts make sense to you and rules and formulas seem natural. This kind of knowledge cannot be gained through rote memorization.
10. MATH IS DONE BY WORKING INTENSELY UNTIL THE PROBLEM IS SOLVED. Solving problems requires both resting and working intensely. Going away from a problem and later returning to it allows your mind time to assimilate ideas and develop new ones. Often, upon coming back to a problem a new insight is experienced which unlocks the solution.
11. SOME PEOPLE HAVE A “MATH MIND” AND SOME DON’T. Belief in myths about how math is done leads to a complete lack of self-confidence. But it is self-confidence that is one of the most important determining factors in mathematical performance. We have yet to encounter anyone who could not attain his or her goals once the emotional blocks were removed.
12. THERE IS A MAGIC KEY TO DOING MATH.  There is no formula, rule, or general guideline which will suddenly unlock the mysteries of math. If there is a key to doing math, it is in overcoming anxiety about the subject and in using the same skills you use to do everything else.

Kea (Nestor notabilis)

The Kea is a large species of parrot found in forested and alpine regions of the South Island of New Zealand. The Kea is the world’s only alpine parrot. Its omnivorous diet includes carrion, but consists mainly of roots, leaves, berries, nectar, and insects. Kea are known for their intelligence and curiosity, both vital to their survival in a harsh mountain environment. Kea can solve logical puzzles, such as pushing and pulling things in a certain order to get to food, and will work together to achieve a certain objective. Called “the clown of the mountains”, it will investigate backpacks, boots, or even cars, often causing damage or flying off with smaller items. Despite being classified as Nationally Endangered in the New Zealand Threat Classification System and Vulnerable in the IUCN Red List and protected by law, Kea are still deliberately shot. photo credits: User:Chmehl ,Dilaudid ,keabiz

They’re also the most intelligent parrot, and possibly even the most intelligent bird overall.

Yes, infact It’s actually quite common. Mostly the changes are subtle and cannot be noticed, but sometimes it is quite severe. About 15% of caucasians change eye color at puberty.
So what causes it?
Well it has to do with how the different colors are created in the first place, it’s all to do with the Amount of pigment. Lots of pigment makes your eyes brown, little pigment makes it blue, and the others are in between. But pigment isnt permanent, it decays and is replaced all the time, so it all has to do with decay rate Vs replacement rate, which can be influenced by lots of things such as hormones (hence the puberty changes,) diet, and environment.
so in reality it would actually be rare to have the exact same eye color constantly.

Hoatzin (Opisthocomus hoazin)

The Hoatzin, also known as the Stinkbird, or Canje Pheasant, is a species of tropical bird found in swamps, riparian forest and mangrove of the Amazon and the Orinoco delta in South America. It is notable for having chicks that possess claws on two of their wing digits. The Hoatzin is pheasant-sized, with a total length of 65 centimetres (26 in). The Hoatzin eats the leaves and to a lesser degree fruits and flowers of the plants which grow in the marshy and riverine habitats where it lives. It clambers around clumsily among the branches, and being quite tame (though they become stressed by frequent visits), often allows close approach and is reluctant to flush. Because of aromatic compounds in the leaves they consume and the bacterial fermentation, the bird has a disagreeable, manure-like odor and is only hunted by humans for food in times of dire need.

Random Fact of the Day: Binary, Trinary, and Larger Star Systems

It’s actually almost rare for a star to be on its own. More than 2/3rds of all stars are in a multiple system, with 2, 3, or more stars all orbiting the systems centre of mass.

Blow your mind with these brain myths you’ve always thought were true.

It’s a drill that shoots frickin’ laser beams 

by Michael Keller

And it was built by a company called Foro Energy with funding assistance from the Department of Energy’s advanced research projects agency, ARPA-E. The agency says the innovation makes drilling for petroleum and geothermal sources of energy faster and cheaper.

Foro engineers overcame major physical obstacles to make their high-powered lasers. They can now deliver laser energy through fiber optic cable over long distances because they figured out how to counter an effect called stimulated Brillouin scattering. This physics problem occurs when the electric field of a high-energy laser triggers vibrations in the fiber that interfere with the movement of photons. The vibrations cause the photons to scatter, often back in the direction from which they traveled.
