Humboldt Squid



Habitat

Humboldt squid live at depths of 660 to 2,300 meters in the eastern Pacific, from Tierra del Fuego north to California. They take their own names Humboldt, from where they lived off the coast of South America. Recently, the giant squid has appeared in the north, precisely in Sitka, in because of ecological problems which may underlie their migration north. Some oceanographers suggest that the warming of the oceans to make their native habitat is threatened, while others speculate that the number of squid predators was increased due to overfishing,

Why the Moon can be colored yellow?

"Yellow moon follow us! If we walk, he also runs, if we ran, he also ran." Is it true that the moon is following us all night long yellow from start to finish? Actually the moon is not always yellow, depending on the time and conditions when we see it, the color of the moon varies slightly. When the new moon appears and when the moon began to sink toward the south at dawn, he colored red.

Because at those times the distance that must be refracted sunlight from the atmosphere to the earth's surface very much, so that short wavelength light and blue will collide with the dust, clouds, and water vapor in the atmosphere so that light will be reflected back while wave lengths of light reddish color is refracted so that we will see more months of red and yellow.
On a clear day the moon is in the sky is blue. This occurs when the air cleaner so that the light that passes through Earth's atmosphere will not be reflected. However, due to air pollution, the sky grew dirty. That's why today we hardly see the moon is blue again. Instead it will be easy for us to see the yellow moon.

So we more often see the moon is yellow because of the increasingly severe air pollution causes the blue light of the moon colliding with objects in the air pollution so that the light is reflected and only the yellow light is refracted until it can be seen on earth.

Tardigrada, this animal can live in 151 Degrees C Temperature



Tardigrada / Tardigrade is also called as the Water Bear is a kind of microscopic animals who live in water, have eight feet and invertebrates. Tardigrade named (slow walkers) by Lazzaro Spallanzani in 1777. Dubbed as well as the Water Bear since limping like a bear. These animals vary in size, the smallest size of less than 0.1 mm, while the largest is only about 1.5 mm.

Tardigrada has a fat body like a caterpillar with the head on the front & 4 segments behind. In each segment there is a pair of clawed feet on the end. Based on observations on the inside of his body, Tardigrada known to have a simple organ systems. They are known to have no respiratory or circulatory systems such as high-level animals. Instead, they breathe with the skin & use gempalnya body to pump body fluids. Their digestive system is also very simple in which food is ingested flowed into a channel-like gut to be absorbed and then dumped the remains through the anus.

According to the Time Theory Physics Scientists



We know that time is a stream that flows from the past to the future. Every time there is change, there is distance, and also death. Time also becomes an omen when born, when birthdays and when the time comes until then extinct. The theory of physics says that time is not absolute, which means time show something relative to a reference.
Exemplified by Albert Einstein, the pioneer of the theory of relativity, for example when a car and look up the object outside the car is not moving, then the visible object is moving. Meanwhile, for those outside the car, then the person in the car said to move. Which is true, Einstein said that both are correct and this became known as the theory of special relativity.
Meanwhile, a more detailed explanation about the time that slows down, also presented in the theory of general relativity. Physicists describe the formula of three-dimensional space, it turns out there is still time referred to as another dimension. This means that in addition to the 3 D, the physicists to introduce the world's 4 D, with additional time. In other words can be guessed almost every place in the universe, has a different time and space with the earth or in any place lainn. To note is that time is also influenced by gravity. The greater the gravity, the slower time passes. From the theory of
