World Best 10 of Discovery Science 2010

Scientists from various fields such as chemistry, astronomy, biology, archeology, and paleontology have managed to find the facts in science spectacular. Here is the best scientific discoveries during the year 2010.

1.       Horned dinosaur in September this year, scientists officially named a new group of dinosaurs called Cosmoceratops. Weight class of dinosaurs reached 2500 pounds. And, that makes it unique is the presence of 15 units of horns on his head.
Cosmoceratops actually been discovered in 2007, but scientists can identify him this year. Group was allegedly living dinosaurs 76 million years ago in what is now known as Utah, USA.

2.       Muons and the Formation of the Universe, Scientists say that the amount of matter and anti matter produced before the big bang should be different. Only difference is what allows the creation of universe.
Previously, the difference was only possible in theory. Until this year, experiments at the Fermilab particle found that muons (sub-atomic particles such as electrons) generated a surplus of 1% anti-muons.
Differences muons and anti-muons are indeed not too much. However, the scientists said the amount was enough to spur the creation of the universe.

3.       Months More Than Wet Sahara, Lunar Crater Observation Mission and Sensing Satellite (LCROSS) successfully found the presence of water on the moon, precisely in the moon's south pole region. The amount of water on the surface of the moon which is found in such research is surprising, more than 50% of the expected.
Water contained in the moon's south pole is contained in the form of ice mixed with other materials. The researchers said the ice that can be processed into pure water. It can save the cost of landing mission to the moon since there is no need to bring water from the earth.

4.       Teotihuacan Pyramids Mexico, Archaeologists who examined the Teotihuacan Pyramids Mexico managed to find a corridor 12 feet wide complete with the roof. With the invention of the corridor, the archaeologists hope to find the road to the cemetery of the rabbi or religious leader in the Mexican civilization.

5.       Genes Cause Aging, Why do some people look older faster? Geneticists have found that it was caused by the act of TERC gene. The gene determines telomere length, a kind of cap found on the ends of chromosomes.
People carrying the gene will tend to experience more rapid aging because telomernya will shorten faster. People who carry one copy of the gene for example, will look the same old with people who are 3-4 years older than him.
Research on the TERC gene were published in the journal Genetics.

6.       Extra Solar Planet, The researchers found that there are many planets outside our solar system. One of them is HIP 13044b planet discovered by astronomers from Indonesia, Johny Setiawan. The planet is actually an extra-solar planets, but entered the Milky Way galaxy.
The discovery of extra-solar planets is the existence of seven planets orbiting the star HD 10180. Meanwhile, the discovery of other planets are also fascinating is Gliese 581g, extra-solar planets orbiting the star at a distance said that was not too cold nor PNAS, like the earth orbiting the sun.

7.     Metamaterial, This discovery made by Professor Martin McCall and Imperial College, London. Metamaterial made is said to be "stirred" the flow of electromagnetic energy. light passing through the metamaterial will be scattered unevenly, forming a gap between space and time.

8.       The discovery of Australopithecus sediba, Scientists have found fossils of Australopithecus sediba, an ancient human species in the region Malapa, South Africa. The fossil was probably derived from the 2 million years ago.
The palaentolog suspect, relates to the fossil hominid Homo erectus by evolutionary then evolved into Homo sapens or modern humans. The discovery of this species, according to the scientists, could complement the data of human evolution.

9.      Ununseptium, Unuseptium which is temporarily named Element 117 is a combination of isotope and calcium berkelium created by scientists at Dubna, Russia. The physicists say that these compounds could indicate "island of stability", where the heaviest element that can last for months.

10.    Cats Secret sipping milk, Scientists from the Massachusetts Institute of Technology (MIT), Virgiania Tech and Princeton University discovered the secret of how a cat slurping milk. They found that when the cat will drink, her tongue mebentuk first letter J.
Due to these capabilities, cats do not need to enter the entire tongue into a container of milk. A form letter allows the formation of milk in the lane between the tongue that moves with the liquid surface. When the cat's mouth shut, milk can be drunk without causing chin became wet.

The Most Voracious Plant in The World

What is the most voracious plant in the world? The answer is Nephentes alata. These plants can take 6000 termites each day to get nutrients.

Hah.., eat termites? Yup, Nephentes alata is a type of carnivorous plant, a plant species that not only absorbing nutrients from the soil, but also get it from animals, especially insects. One type of carnivorous insects that use plants, especially Nephentes alata, is a termite. Not just fly as often used as an example.

Nephentes alata has a shape like a cup with a hole in the middle. The lip of the cup containing the nectar that serves as a trap for insects. While the inside of the cup has a slippery surface, making the insects can easily fall into the cup.

In the wild, Nephentes alata strategy for food can get this to work well. Every day, thousands of insects come flocking Nephentes alata. They thronged the lips the cup to his feed on nectar and in the middle density, some termite-crossed forced to fall into the inside of the cup.

If it falls, then finished already. Nephentes alata Cup will shut, do not allow insects to escape. The termites have to give him a meal for Nephentes alata. Nephentes alata will absorb the nitrogen in termites, and then use them as nutrients.

Marine Algae

Marine algae which belong to a group of plants called algae. Many algae are plants that are very small and consists of a single cell. They are simple plants, without flowers, leaves, or stems that remain. Algae can live in almost all places, a tree trunk, in the pool, and at sea. Marine algae are the largest type of algae. The algae can grow to 65 feet in length. Marine algae growing along the rocky shore or meet the surface water with air in the bag on his strand. This plant can not live more deeply, because not enough light to perform photosynthesis.

Marine algae that live along the coast often have a heavy vacuum. The vacuum is also called a fast catcher. This fast catcher is the anchor of this plant. Therefore, marine algae are not washed away by high tides.

In some countries, like Japan and Ireland, at certain times, these marine algae will be harvested. This plant is widely used as food, fertilizer plants, and to make shampoo, toothpaste, and ice cream.

Age of Earth

Scientists say that the earth was about 4600 million years. Earth is the only place that is different from the planets we know today. Earth covered volcano spewing hot gas, rock, and water vapor into the air. During the cold surface of the earth, the rocks to harden and form the soil. Water vapor gets cold, then condenses and falls as rain storms are great. Most of the rain drying on hot surfaces. Some were filling the first sea that is almost boiling and such as acetic acid. In place of the oxygen we breathe now, the air filled with toxic gases, like carbon dioxide, ammonia, hydrogen sulfide, and methane.

Scientists who study rocks called geologists. In 1984, the oldest known rocks on Earth discovered by geologists in Canada. These stones are more than 3690 million years. The objects of the first life is very small cells that lived about 3200 million years ago. While the dinosaur lived about 200 to 60 million years ago, but our ancestors who first is gone up to about 4 million years ago.
