1. First the chicken or the egg?Surprisingly enough, the answer is chicken. The explanation is as follows:A British researcher, Colin Freeman of the University of Sheffield, doing research on a protein found in egg shells called ovocledidin-17. Using a supercomputer named Hector located in Edinburgh, Scotland, Mr. Colin and his team successfully performed the simulation process biomineralisasi the process of formation of minerals or solid organs in living beings as described in the scientific paper entitled "Structural Control of Crystal Nuclei by an Eggshell Protein". From there, it transpired that the protein ovocledidin-17 was also found in chicken ovarian cells. Protein ovocledidin-17 serves to accelerate the formation of the eggshell so within 24 hours, the eggs will be ready to be issued. Although not a primary objective of the research, which may provide an answer to the question "Where are forewarned or the egg? '. And the answer is chicken, eggs need to reason ovocledidin-17 protein contained in chicken ovaries in order to form.Hector supercomputer2. Why does hair turn white when older?A collection of scientists from Bradford University, UK in collaboration with a number of German scientists managed to find the answers to hair bleaching process. In a study in Mainz and Luebeck, Germany, known in his day the human body produces the so-called hydrogen peroxide (H2O2), a substance that is liquid bleach. When a person ages, these substances are produced more quickly and a lot. Because these substances are whitened, these substances are natural pigments hold a person's hair color so the hair will grow white.Bleached hair due to aging3. What's going on in the body of the moon?Using data transmitted by several seismometers left on the moon by the Apollo missions until 1977, a professor and his student in the School of Earth and Space Exploration in ASU's College of Liberal Arts and Sciences, Arizona State University named Ed Garnero and Peiying ( Patty) Lin, developed a method of analysis called array processing to figure out what exactly is contained in the belly of the month.Patty Lin was studying a material that comes from the moonBy way of stacking piles (layering) recording seismic signals and study at the same time, they are able to recognize the weak signals that were previously undetectable. The echo of the signal is used to map out what is in the stomach months. Their data provide evidence that most of the contents in the stomach consisting of a solid substance containing iron-rich core that is wrapped in liquid iron in the outer part. This gives a semblance of what is in the stomach the moon with what's in the bowels of the earth, because they are formed from a mixture of iron, nickel and other light elements such as sulfur.4. Why is the finger becomes wrinkled if soak too long?A question that has not been answered until recently this is why your fingers wrinkle if it is too long to be wading in water and why we are not crushed like skin tissue as it has absorbed so much water.Apparently there is a mathematical explanation behind it all.Shell gyroid structureKnown fiber and keratin that make up the human skin to form a structure called gyroids. With mathematical descriptions, this structure allows the skin stretched so wide up to seven times the size of the original because of the elements that make up the skin fibers interconnected with many other fiber elements in the skin.When our skin becomes wrinkled, it absorbs a lot of water so that the skin increases the volume becomes larger. And since the other parts (such as muscles and bones) not go bigger, it causes the skin to become wrinkled to adjust the proportion of the shape with the other hand.How does scratching relieve itching?A recent study found that the itching is not caused by the skin itself, and relieving itching scratching also not true. Rather, a sense of itching and scratching caused by uncomfortable governed by a group of neurons in the spinal nervous system. Here are the steps conducted by researchers at the University of Minnesota led by Glenn Giesler against a monkey to get the facts.Giving light anesthesia in monkeys to calm her down.Replacing electro-nodes in monkeys for detecting neural activity spine.Injecting histamine on foot ape to give itching.Observed increased activity of the spinal cord caused apes.Scratching foot ape, but not at the site of histamine injected.Observed decrease in activity of the spinal cord monkeys, apes in other words be quiet though not scratch the itch at the site.This gives evidence that the scratching works by affecting the spinal cord to provide comfortable effect, not on where the itch itself.5. How do cats drink?So far, people think that the way cats and dogs drink is the same, namely by "scooping" the water with his tongue. A joint study by the Massachusetts Institute of Technology, Virginia Polytechnic Institute in the United States, proving cats do not drink that way.Here's how cats drink:First his little cat will stick its tongue into the water, then with a lightning movement he pulled back which resulted in a number of water will spring up. And before the water fell back due to the force of gravity, the cat will "catch" with his mouth. It happens so fast that in a second cat was able to repeat it to 4 times / sip.
