It's called "Naia" and 12,000 years ago lived in the Yucatan Peninsula. It is one of the oldest skeletons found to date in the Americas and by far the most comprehensive. His remains were submerged 40 meters below sea level, in the depths of a cave flooded called Black Hole. Their genetic analysis yielded enlightening data on the origins of the first American inhabitants, crossed from Asia in the last ice age via a land bridge from what is now the Bering Strait.

Summary

Planarian (class of Turbellaria) are worms that can be found in fresh water, oceans and wetlands. For his incredible ability to regenerate, the Scottish naturalist John Dalyell defined them as the "immortal worm under the blade of a knife" in the early nineteenth century. Since then, scientists have done all sorts of dirty tricks to planarians: they've cut the head, tail, both longitudinally and have dissected into pieces. It always survives.

But its algorithm has not only successfully replicated what humans have done. In one of the earliest examples of science done by robot (not to be confused with robotics), this system of artificial intelligence discovered at least two new elements to the puzzle of regeneration of these worms. "He predicted the existence of two proteins that should be part of the network," said Levin.



Opinion

In my opinion, if a machine discovers the algorithm of the Turbellaria and confirm the discovery of this system of artificial intelligence, it would be one of the first discoveries made by a machine. There are already robot surgeons, algorithms that outperform humans in an increasing number of activities. Achievements like the human genome would not have been possible without the assistance of powerful computers and no less powerful artificial agents. But finding something new is another thing. The advantage of robotic systems is that they can work out cheaper, faster and with greater accuracy and longer than humans, but we have to thing on the inconvinients it can produce to humns.

Glossary
Dissect: To cut open something, especially a dead body or a plant, and study its structure.
Blade: The flat part on a knife or similar tool or weapon, with a very thin edge used for cutting.

Summary

About 10 years ago, the Canadian geologist Peter Hewes found something looming on a cliff overlooking the Oldman River in southwestern Alberta, Canada. Today the scientific journal Current Biology published the study on what proved to be an almost complete skull of a new and unusual species of horned dinosaur, a close relative of Triceratops known. The researcher Caleb Brown Royal Tyrrell Museum of Paleontology is the study author that comes now to light and that brings a new perspective about ceratópsidos, the gender of the horned dinosaurs. "The specimen was found in a region of Alberta where horned dinosaurs had never met before, so from the beginning we knew it was an important finding," says Brown. "But it was not until we were slowly removing the specimen from the rocks in the laboratory when the whole anatomy of the skull was discovered, along with its strange characteristics," he adds.

Opinion

In my opinion, the most discoveries the science do, the most we would know about the animales which had lived before the humans. Dinosaurs are a very interesting thing to learn something about them because it has to be with the way the life in the Earth have been evolutioning since the creation till nowadays.
The 'Hellboy' is a very coriuos and insteresting animal and also it is the reconstruction of it. It is always amazing how science progress so fast in discoveries...

Glossary

Horn: A hard, pointed, often curved part that grows from the top of the head of some animals, or the hard substance of which a horn is made.
Looming: To appear as a large, often frightening or unclear shape or object.
Cliff: A high area of rock with a very steep side, often on a coast.

Summary

Google has activated a tool which is very useful: it helps you locate your lost phone through a computer. Its functioning is easy. The user only has to search their mobile using their computer and, after this operation, the phone will ring as if it was a call. Thanks to Google Maps, you will also be able to see where it is in case it's not near you.

Opinion

I think this is one of the most useful tools for our phones that has been created. Every day lots of new apps are made and most of them are useless whereas this one is frankly profitable. How many times have we lost our phone and we couldn't find it? Of course, at the end we found it but after a lot of time searching it. Now we won't lose our time seeking for them. But I think the most effective custom of this implement is in robbery terms. This will let us find where our phones are in case it has been robbed and report it to the police. In conclusion, it is my belief that this kind of app is going to be very helpful and useful in our lives.

Glossary

User: a person who uses a computer.
Tool: anything used to accomplish a task. An instrument for some purpose or work.

Corner of Scientist. (Manel's Part)

ISAAC NEWTON.

What has he done?

WORKS ON LIGHT
Between 1670 and 1672 he worked extensively on issues related to optics and the nature of light. Newton showed that white light was formed by a band of colors (red, orange, yellow, green, cyan, blue and violet) that could be separated by a prism. As a result of these studies concluded that any refractor suffer a type currently known as chromatic aberration, which is the scattering of light in different colors through a lens aberration. To avoid this problem invented a reflecting telescope (known as a Newtonian telescope).

LAWS OF UNIVERSAL GRAVITATION.
Bernard Cohen says that "The highlight of the Scientific Revolution was the discovery by Isaac Newton's law of universal gravitation." With a simple law, Newton gave to understand the most important physical phenomena of the observable universe, explaining the three laws of Kepler

THE LAWS OF DYNAMICS.

These laws are three, and talk and study the inertia force and action-reaction of a particle.


TEOLOGY.
Newton was deeply religious all his life. Son of Puritan parents spent more time studying the Bible to science. An analysis of everything that Newton wrote reveals that some 3.6 million words only one million were devoted to science, while 1.4 million had to do with theology. A list of fifty-eight sins that wrote to the 19 years in which you can read "Threatening my father and mother Smith to burn them and the house with them," known.

SUM UP.
Researchers at the Gregorio Maranon hospital in Madrid have been working on a new source of hearts for transplant years. The project consists of empty hearts of cardiac cells from deceased donors and leave them in the internal structure.

They have managed to sow small pieces of stem cell matrix and develop in the laboratory samples of heart tissue the size of a two Euro coin similar to those of the heart itself capable of beating synchronously properties. "They ordered electrical activity and proper contraction," said Francisco Fernández-Avilés, head of the cardiology department of the Madrid hospital and project coordinator.

OPINION.
As I said in other news, progress in health appears to me something indispenasble, because life is the most precious thing and we should learn to keep it.

I do not know a lot about stem cells, but the little I know, have the ability to regenerate tissues and cells.

VOCABULARY.

Stem cells = Células madre.

SUM UP.

A herpes virus genetically modified can stop the progression of more aggressive skin cancer, by selective elimination of tumor cells and activating the body's defenses, according to results of a clinical trial involving 436 patients published today.

Melanoma is the most serious type of skin cancer. Each year 132,000 new cases worldwide occur, according to the World Health Organization. In Spain, 90% of women and 74% of men survive more than five years to this type of malignancy.

OPINION.

Personally, I think all the economic funds must be dedicated to finding cures for terminal diseases and no end.
I think a breakthrough discovery of the variant of herpes that can solve the problem.
