Seaweeds in the Mediterranean 200 thousand years old!!


Seaweeds in the Mediterranean 200 thousand years old!!

 Recently, Australian scientists have detects the genetic material of samples of seaweeds huge scientific name (Busadonaa Ohinnika Posidonia oceanica) located along the distance amounting to more than 3,200 km in the Mediterranean Sea between Spain west and Cyprus to the east and is likely to scientists that the age of these herbs are nearly200 thousand years and is thus the oldest living organism on earth.

These herbs that have been discovered recently lived much longer than its predecessor colony (Bando Pando) and located in the U.S. state of Utah, which scientists estimated age of 80 thousand years. (For more on this and other plants of the longest-lived organisms, Read: Tour of the longest and shortest ages organisms that live on the planet). Previous image to Bando colony.

Says the world (Carlos Duarte Carlos Duarte) from the University of Western Australia that the reason for offering these weeds in a lifetime back to being multiply manner asexual by reproducing itself as it produces new branches of large-size large numbers slowly storing food that they can continue to live inin bad conditions.

Scientists say this weed with a mass of more than 6000 tons threatened with extinction dramatically from several factors, the most important of drilling operations and construction taking place in addition to the coast in terms of global warming over the Earth's temperature forcing organisms to move to higher altitudes in the water inside to escapeof increased temperature at the bottom, but in the case of the Mediterranean basin, it becomes difficult because it is a closed basin as Europe is bordered to the north and from the south Asia, and also threatening the lives of these herbs also poor quality of water also caused by global warming.

Colonial receive daily large numbers of fibrous balls, these balls are made ​​of dead leaves and you can see all these balls on the shores of countries overlooking the Mediterranean basin. Perhaps this is the way the old seaweed in the notification of humans to their environment at risk. The following picture to a number of these balls.



Astronomers discover a planet at least three of diamonds


Astronomers discover a planet at least three of diamonds

Astronomers discovered a planet twice the size of the diamond planet is the main ingredient which revolves around a star can be seen with the naked eye.

And spins planet rock dubbed astronomers name "Kankera 55" around a star like the sun on a 40 light-years away, and the light-year is the distance light travels in a year and an estimated 9.46 trillion miles, and no planet in a range of cancer and spins very quickly make the year in which expire within 18 hours, only accounts for the planet.

He discovered a research team of U.S. French planet that has a diameter twice the diameter of the Earth and reach mass to eight times the mass, and gives the planet the same density of the Earth, although planets diamond observed by the thought denser much, and is characterized by the planet also strongly temperature as the temperature reaches the surfaceto 1648 degrees Celsius.

And said Nico Madehosodhan the researcher at Yale University who is due to publish the results of his research in the journal (Astrophysics), "the surface of this planet probably covered with graphite and diamonds no water and granite."

The study estimated that participated in Olivier Muasis, a researcher at the Institute of Astrophysics in Toulouse, France, that a third of the mass of the planet, at least - an estimated three times the mass of the earth - a diamond may be, according to the reported news agency "Reuters".

And discovered by diamond planets was the key element, but this is the first time where discovers a planet orbiting a star like the sun, which is subject to a detailed study of this form.

8 million bat migration from Kanasa Park African Republic of Zambia


8 million bat migration from Kanasa Park African Republic of Zambia

It's hard to see the sky amid a scene repeated only once a year, and this scene appears when you fly more than 8 million bat in one of the largest migrations of mammals in Africa and also the most exciting.


Did not find a bat fruit that reaches over the wings to 6 feet of any meters and eighty centimeters, but to live on a patch of land small an area of ​​about 4050 square meters in a small corner of the park, "Kanasa" national, after the return of the bat to her home after caught daily, carrying every treeup to 10 tons of bats, making the area one of the most densely crowded warm-blooded mammals in the world.


This has been found "Lucas" that bats leave her home in the tops of the trees when the sun to come back with the dawn to sleep. He believes that the number of bats that are involved in the migration is more than the number of bulls and zebras African collected. It is worth mentioning that this kind of color bat like a straw, a subspecies of "fruit bat" found in most parts of sub-Saharan Africa. The large amount of fruit that feed on these organisms allow them access to the weight of 311 grams. And live for about 30 years.
